Folks, I am trying to compile the latest PPL on bluefire, an IBM Power6 running AIX 5.3, with IBM's compiler xlc/xlC (http://www.cisl.ucar.edu/docs/bluefire/be_quickstart.html#software)

Unfortunately, while the configure script is happy (see config.log for details), the compilation fails as described in the attached make.log and I have no clues about it.

Note that before it was failing with the following one, which I believe was due to a different make version being used, but might be the first culprit (I have the make.log for this too but I'm not sending it right now):

/usr/bin/sed -f ./ppl-config.sed >ppl-config.h "../ppl-config.h", line 1.0: 1540-0809 (W) The source file is empty.

Do you have any recommendations about what I can do to fix the issue?

PS: I speak Italian, but I'm not sure if this list is read just by Italian, despite its .it domain.

NAME xlc, xlc++, xlC, cc, c89, c99, xlCcore, xlc++core and related commands - invoke the IBM XL C/C++ compiler.

SYNTAX <invocation-command> [ <option> | <inputfile> ] ...

DESCRIPTION The invocation commands compile C and C++ source files. The commands and their recommended uses are described below.

Invocations Usage (supported standards) _________________________________________________________

xlc, xlc_r, xlc_r4, Compile C source files. xlc_r7, xlc128, xlc128_r, (ANSI C89, ISO C99, xlc128_r4, xlc128_r7 IBM language extensions)

xlc++, xlc++_r, xlc++_r4, Compile C++ source files. xlc++_r7, xlc++128, xlc++128_r, xlc++128_r4, xlc++128_r7, xlC, xlC_r, xlC_r4, xlC_r7, xlC128, xlC128_r, xlC128_r4, xlC128_r7

cc, cc_r, cc_r4, cc_r7, Compile legacy code that cc128, cc128_r, cc128_r4, does not conform to Standard cc128_r7 C. (pre-ANSI C)

c89, c89_r, c89_r4, Compile C source files with c89_r7, c89_128, c89_128_r, strict conformance to the c89_128_r4, c89_128_r7 C89 standard. (ANSI C89)

c99, c99_r, c99_r4, Compile C source files with c99_r7, c99_128, c99_128_r, strict conformance to the c99_128_r4, c99_128_r7 C99 standard. (ISO 99)

xlc++core, xlc++core_r, Compile C++ source files xlc++core_r7, xlc++core128, but the compiler will xlc++core128_r, link only to the core of xlc++core128_r7, xlCcore, the runtime library. xlCcore_r, xlCcore_r7, xlC128core, xlC128core_r, xlC128core_r7

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified. Default: o norsqrt at -O2 optimization. o rsqrt when when -qnostrict or -O3 or higher optimization level is in effect. single | nosingle Allows single-precision arithmetic instructions to be generated for single- precision floating-point values. All PowerPC processors support single-precision instructions; however, if you wish to preserve the behavior of applications compiled for earlier architectures, in which all floating- point arithmetic was performed in double- precision and then truncated to single- precision, you can use -qfloat=nosingle:norndsngl. This suboption provides computation precision results compatible with those provided by the deprecated options -qarch=com|pwr|pwrx|pwr2|p2sc|601|602|603. Default: single spnans | nospnans Detects signalling NaN on conversion from single-precision to double-precision. Default: nospnans

Default: -yn

For decimal floating-point types, <rounding_mode> is one of the following: di = round toward infinities (away from zero) dm = round toward minus infinity dn = round to the nearest representable number, ties to even dna = round to the nearest representable number, ties away from zero dnz = round to the nearest representable number, ties toward zero dp = round toward plus infinity dz = round toward zero

Default: -ydn

-qalias=<suboptions_list> Specifies the aliasing assertions to be applied to your compilation unit. <suboptions_list> is a colon-separated list of the following options:

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled. Specifying norestrict disables optimizations for restrict-qualified pointers. -qalias=restrict is independent from other -qalias suboptions. typeptr | notypeptr Pointers to different types are never aliased if typeptr is specified, but may be aliased if notypeptr is specified.

-qarch=<suboption> Specifies the general processor architecture for which the code (instructions) should be generated. In general, the -qarch option allows you to target a specific architecture for the compilation. For any given -qarch setting, the compiler defaults to a specific, matching -qtune setting, which can provide additional performance improvements. The suboptions are:

auto Automatically detects the specific architecture of the compiling machine. It assumes that the execution environment will be the same as the compilation environment. 403 Produces object code containing instructions that will run on the PowerPC 403 hardware platform. 604 Produces an object that contains instructions that run on PowerPC 604 systems. pwr3 Produces an object that contains instructions that run on the POWER3 hardware platforms. pwr4 Produces an object that contains instructions that run on the POWER4 hardware platforms. pwr5 Produces an object that contains instructions that run on the POWER5 hardware platforms. pwr5x Produces an object that contains instructions that run on the POWER5+ hardware platforms. pwr6 Produces object code containing instructions that will run on the POWER6 hardware platforms running in POWER6 architected mode.

Using -q64 with ppc upgrades the architecture to ppc64. ppc64 Produces object code that will run on any 64- bit PowerPC hardware platform. When compiled in 32-bit mode, the resulting object code may include instructions that are not recognized or behave differently when run on 32-bit PowerPC platforms. ppcgr In 32-bit mode, produces object code containing optional graphics instructions for PowerPC hardware platforms. In 64-bit mode, produces object code containing optional graphics instructions that will run on 64-bit PowerPC platforms, but not on 32-bit-only platforms. Using -q64 with ppcgr upgrades the architecture to ppc64gr. ppc64gr Produces object code that will run on any 64- bit PowerPC hardware platform that supports the optional graphics instructions. ppc64grsq Produces object code that will run on any 64- bit PowerPC hardware platform that supports the optional graphics and square root instructions. ppc64v Produces object code that will run on any 64- bit PowerPC hardware platform that supports the optional vector instructions, such as a PowerPC 970. ppc970 Generates instructions specific to PowerPC 970 processors. rs64a Produces an object that contains instructions that run on an RS64I hardware platform. rs64b Produces an object that contains instructions that run on an RS64II hardware platform. rs64c Produces an object that contains instructions that run on an RS64III hardware platform.

Default: -qarch=ppc

-qcache=<suboptions_list> Describes the cache configuration for a specific target execution machine, where <suboptions_list> is a colon-separated list of one or more of the following suboptions:

assoc=<number> Specifies the set associativity of the cache, where <number> is one of the following: 0 Direct-mapped cache 1 Fully associative cache (number > 1) n-way set associative cache auto Automatically detects the specific cache configuration of the compiling machine. It assumes that the execution environment will be the same as the compilation environment. cost=<cycles> Specifies the performance penalty, in CPU cycles, resulting from a cache miss. level=<level> Specifies which level of cache is affected, where level is one of the following:: 1 Basic cache 2 Level-2 cache 3 Table Lookaside Buffer (TLB) If a machine has more than one level of cache, use a separate -qcache option. line=<bytes> Specifies the line size of the cache. size=<Kbytes> Specifies the total size of the cache. type=<cache_type> The settings apply to the specified type of cache, where <cache_type> is one of the following: C or c = Combined data and instruction cache D or d = Data cache I or i = Instruction cache

Default: The -qtune setting determines the optimal default -qcache settings for most typical compilations. -O4, -O5, or -qipa must be specified with the -qcache option.

-qcompact | -qnocompact Reduces code size where possible, at the expense of execution speed. Code size is reduced by inhibiting optimizations that replicate or expand code inline. This option takes effect only if -O2 or higher is also used.

Default: -qnocompact

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata. (C++) Variable names must be specified using their mangled names.

-qtocdata | -qnotocdata Marks all data as local.

Default: -qnotocdata (marks all data as imported)

-qdirectstorage | -qnodirectstorage Informs the compiler that write-through-enabled or cache-inhibited storage may be referenced.

Default: -qnodirectstorage

-qenablevmx | -qnoenablevmx Enables the generation of vector instructions for processors that support them. These instructions can offer higher performance when used with algorithmic-intensive tasks such as multimedia applications. For -qenablevmx to have effect, the architecture specified by the -qarch option must support vector instructions. If -qnoenablevmx is in effect, -qaltivec, -qvecnvol, and -qhot=simd cannot be used.

Default: -qnoenablevmx

-qfdpr | -qnofdpr Collects information about programs for use with the IBM Feedback Directed Program Restructuring (FDPR) performance-tuning utility.

Default: -qnofdpr

-qhot[=<suboption>] | -qnohot Specifies whether or not to perform high-order transformations during optimization. The suboptions are:

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-qspill=<size> Specifies the size of the register allocation spill area in bytes.

Default: -qspill=512

-t<programs_list> Applies the prefix from the -B option to the specified programs in <programs_list>. <programs_list> is a chain (i.e: -tbcI) of one or more of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-W<program>,<options_list> Gives the specified option(s) to the compiler program, <program>. <options_list> is a comma- separated list of one or more options. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = c++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = linkage helper (C++ only) p = Preprocessor

NAME xlc, xlc++, xlC, cc, c89, c99, xlCcore, xlc++core and related commands - invoke the IBM XL C/C++ compiler.

SYNTAX <invocation-command> [ <option> | <inputfile> ] ...

DESCRIPTION The invocation commands compile C and C++ source files. The commands and their recommended uses are described below.

Invocations Usage (supported standards) _________________________________________________________

xlc, xlc_r, xlc_r4, Compile C source files. xlc_r7, xlc128, xlc128_r, (ANSI C89, ISO C99, xlc128_r4, xlc128_r7 IBM language extensions)

xlc++, xlc++_r, xlc++_r4, Compile C++ source files. xlc++_r7, xlc++128, xlc++128_r, xlc++128_r4, xlc++128_r7, xlC, xlC_r, xlC_r4, xlC_r7, xlC128, xlC128_r, xlC128_r4, xlC128_r7

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified. Default: o norsqrt at -O2 optimization. o rsqrt when when -qnostrict or -O3 or higher optimization level is in effect. single | nosingle Allows single-precision arithmetic instructions to be generated for single- precision floating-point values. All PowerPC processors support single-precision instructions; however, if you wish to preserve the behavior of applications compiled for earlier architectures, in which all floating- point arithmetic was performed in double- precision and then truncated to single- precision, you can use -qfloat=nosingle:norndsngl. This suboption provides computation precision results compatible with those provided by the deprecated options -qarch=com|pwr|pwrx|pwr2|p2sc|601|602|603. Default: single spnans | nospnans Detects signalling NaN on conversion from single-precision to double-precision. Default: nospnans

Default: -yn

For decimal floating-point types, <rounding_mode> is one of the following: di = round toward infinities (away from zero) dm = round toward minus infinity dn = round to the nearest representable number, ties to even dna = round to the nearest representable number, ties away from zero dnz = round to the nearest representable number, ties toward zero dp = round toward plus infinity dz = round toward zero

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled. Specifying norestrict disables optimizations for restrict-qualified pointers. -qalias=restrict is independent from other -qalias suboptions. typeptr | notypeptr Pointers to different types are never aliased if typeptr is specified, but may be aliased if notypeptr is specified.

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata. (C++) Variable names must be specified using their mangled names.

-qtocdata | -qnotocdata Marks all data as local.

Default: -qnotocdata (marks all data as imported)

-qdirectstorage | -qnodirectstorage Informs the compiler that write-through-enabled or cache-inhibited storage may be referenced.

Default: -qnodirectstorage

-qenablevmx | -qnoenablevmx Enables the generation of vector instructions for processors that support them. These instructions can offer higher performance when used with algorithmic-intensive tasks such as multimedia applications. For -qenablevmx to have effect, the architecture specified by the -qarch option must support vector instructions. If -qnoenablevmx is in effect, -qaltivec, -qvecnvol, and -qhot=simd cannot be used.

Default: -qnoenablevmx

-qfdpr | -qnofdpr Collects information about programs for use with the IBM Feedback Directed Program Restructuring (FDPR) performance-tuning utility.

Default: -qnofdpr

-qhot[=<suboption>] | -qnohot Specifies whether or not to perform high-order transformations during optimization. The suboptions are:

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

NAME xlc, xlc++, xlC, cc, c89, c99, xlCcore, xlc++core and related commands - invoke the IBM XL C/C++ compiler.

SYNTAX <invocation-command> [ <option> | <inputfile> ] ...

DESCRIPTION The invocation commands compile C and C++ source files. The commands and their recommended uses are described below.

Invocations Usage (supported standards) _________________________________________________________

xlc, xlc_r, xlc_r4, Compile C source files. xlc_r7, xlc128, xlc128_r, (ANSI C89, ISO C99, xlc128_r4, xlc128_r7 IBM language extensions)

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time.

Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-qspill=<size> Specifies the size of the register allocation spill area in bytes.

Default: -qspill=512

-W<program>,<options_list> Gives the specified option(s) to the compiler program, <program>. <options_list> is a comma- separated list of one or more options. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = c++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = linkage helper (C++ only) p = Preprocessor

NAME xlc, xlc++, xlC, cc, c89, c99, xlCcore, xlc++core and related commands - invoke the IBM XL C/C++ compiler.

SYNTAX <invocation-command> [ <option> | <inputfile> ] ...

DESCRIPTION The invocation commands compile C and C++ source files. The commands and their recommended uses are described below.

Invocations Usage (supported standards) _________________________________________________________

xlc, xlc_r, xlc_r4, Compile C source files. xlc_r7, xlc128, xlc128_r, (ANSI C89, ISO C99, xlc128_r4, xlc128_r7 IBM language extensions)

xlc++, xlc++_r, xlc++_r4, Compile C++ source files. xlc++_r7, xlc++128, xlc++128_r, xlc++128_r4, xlc++128_r7, xlC, xlC_r, xlC_r4, xlC_r7, xlC128, xlC128_r, xlC128_r4, xlC128_r7

cc, cc_r, cc_r4, cc_r7, Compile legacy code that cc128, cc128_r, cc128_r4, does not conform to Standard cc128_r7 C. (pre-ANSI C)

c89, c89_r, c89_r4, Compile C source files with c89_r7, c89_128, c89_128_r, strict conformance to the c89_128_r4, c89_128_r7 C89 standard. (ANSI C89)

c99, c99_r, c99_r4, Compile C source files with c99_r7, c99_128, c99_128_r, strict conformance to the c99_128_r4, c99_128_r7 C99 standard. (ISO 99)

xlc++core, xlc++core_r, Compile C++ source files xlc++core_r7, xlc++core128, but the compiler will xlc++core128_r, link only to the core of xlc++core128_r7, xlCcore, the runtime library. xlCcore_r, xlCcore_r7, xlC128core, xlC128core_r, xlC128core_r7

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified. Default: o norsqrt at -O2 optimization. o rsqrt when when -qnostrict or -O3 or higher optimization level is in effect. single | nosingle Allows single-precision arithmetic instructions to be generated for single- precision floating-point values. All PowerPC processors support single-precision instructions; however, if you wish to preserve the behavior of applications compiled for earlier architectures, in which all floating- point arithmetic was performed in double- precision and then truncated to single- precision, you can use -qfloat=nosingle:norndsngl. This suboption provides computation precision results compatible with those provided by the deprecated options -qarch=com|pwr|pwrx|pwr2|p2sc|601|602|603. Default: single spnans | nospnans Detects signalling NaN on conversion from single-precision to double-precision. Default: nospnans

This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled. Specifying norestrict disables optimizations for restrict-qualified pointers. -qalias=restrict is independent from other -qalias suboptions. typeptr | notypeptr Pointers to different types are never aliased if typeptr is specified, but may be aliased if notypeptr is specified.

For -qenablevmx to have effect, the architecture specified by the -qarch option must support vector instructions. If -qnoenablevmx is in effect, -qaltivec, -qvecnvol, and -qhot=simd cannot be used.

Default: -qnoenablevmx

-qfdpr | -qnofdpr Collects information about programs for use with the IBM Feedback Directed Program Restructuring (FDPR) performance-tuning utility.

Default: -qnofdpr

-qhot[=<suboption>] | -qnohot Specifies whether or not to perform high-order transformations during optimization. The suboptions are:

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-qspill=<size> Specifies the size of the register allocation spill area in bytes.

NAME xlc, xlc++, xlC, cc, c89, c99, xlCcore, xlc++core and related commands - invoke the IBM XL C/C++ compiler.

SYNTAX <invocation-command> [ <option> | <inputfile> ] ...

DESCRIPTION The invocation commands compile C and C++ source files. The commands and their recommended uses are described below.

Invocations Usage (supported standards) _________________________________________________________

xlc, xlc_r, xlc_r4, Compile C source files. xlc_r7, xlc128, xlc128_r, (ANSI C89, ISO C99, xlc128_r4, xlc128_r7 IBM language extensions)

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified.

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled.

Using -q64 with ppc upgrades the architecture to ppc64. ppc64 Produces object code that will run on any 64- bit PowerPC hardware platform. When compiled in 32-bit mode, the resulting object code may include instructions that are not recognized or behave differently when run on 32-bit PowerPC platforms. ppcgr In 32-bit mode, produces object code containing optional graphics instructions for PowerPC hardware platforms. In 64-bit mode, produces object code containing optional graphics instructions that will run on 64-bit PowerPC platforms, but not on 32-bit-only platforms.

Default: The -qtune setting determines the optimal default -qcache settings for most typical compilations. -O4, -O5, or -qipa must be specified with the -qcache option.

-qcompact | -qnocompact Reduces code size where possible, at the expense of execution speed. Code size is reduced by inhibiting optimizations that replicate or expand code inline. This option takes effect only if -O2 or higher is also used.

Default: -qnocompact

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata.

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-qspill=<size> Specifies the size of the register allocation spill area in bytes.

Default: -qspill=512

-W<program>,<options_list> Gives the specified option(s) to the compiler program, <program>. <options_list> is a comma- separated list of one or more options. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = c++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = linkage helper (C++ only) p = Preprocessor

xlc++core, xlc++core_r, Compile C++ source files xlc++core_r7, xlc++core128, but the compiler will xlc++core128_r, link only to the core of xlc++core128_r7, xlCcore, the runtime library. xlCcore_r, xlCcore_r7, xlC128core, xlC128core_r, xlC128core_r7

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified. Default: o norsqrt at -O2 optimization. o rsqrt when when -qnostrict or -O3 or higher optimization level is in effect. single | nosingle Allows single-precision arithmetic instructions to be generated for single- precision floating-point values. All PowerPC processors support single-precision instructions; however, if you wish to preserve the behavior of applications compiled for earlier architectures, in which all floating- point arithmetic was performed in double- precision and then truncated to single- precision, you can use -qfloat=nosingle:norndsngl. This suboption provides computation precision results compatible with those provided by the deprecated options -qarch=com|pwr|pwrx|pwr2|p2sc|601|602|603. Default: single spnans | nospnans Detects signalling NaN on conversion from single-precision to double-precision. Default: nospnans

-qldbl128 | -qnoldbl128 Specifies whether to increase the long double size from 64 to 128 bits. This is equivalent to -qlongdouble.

Default: -qnoldbl128

-qlongdouble | -qnolongdouble Specifies whether to increase the long double size from 64 to 128 bits. This is equivalent to -qldbl128.

Default: -qnolongdouble

-qlonglit | -qnolonglit Makes unsuffixed literals into the long type in 64-bit mode.

Default: -qnolonglit

-y<rounding_mode> Specifies the compile-time rounding mode of constant floating-point expressions.

For binary floating-point types, <rounding_mode> is one of the following: m = round toward minus infinity n = round to the nearest representable number, ties to even p = round toward plus infinity z = round toward zero

Default: -yn

For decimal floating-point types, <rounding_mode> is one of the following: di = round toward infinities (away from zero) dm = round toward minus infinity dn = round to the nearest representable number, ties to even dna = round to the nearest representable number, ties away from zero dnz = round to the nearest representable number, ties toward zero dp = round toward plus infinity dz = round toward zero

Default: -ydn

Object code control options -q32, -q64 Selects either 32-bit or 64-bit compilation mode. Use the -q32 and -q64 options, along with the -qarch and -qtune compiler options, to optimize the output of the compiler to the architecture on which that output will be used.

-qalias=<suboptions_list> Specifies the aliasing assertions to be applied to your compilation unit. <suboptions_list> is a colon-separated list of the following options:

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled. Specifying norestrict disables optimizations for restrict-qualified pointers. -qalias=restrict is independent from other -qalias suboptions. typeptr | notypeptr Pointers to different types are never aliased if typeptr is specified, but may be aliased if notypeptr is specified.

Using -q64 with ppc upgrades the architecture to ppc64. ppc64 Produces object code that will run on any 64- bit PowerPC hardware platform. When compiled in 32-bit mode, the resulting object code may include instructions that are not recognized or behave differently when run on 32-bit PowerPC platforms. ppcgr In 32-bit mode, produces object code containing optional graphics instructions for PowerPC hardware platforms. In 64-bit mode, produces object code containing optional graphics instructions that will run on 64-bit PowerPC platforms, but not on 32-bit-only platforms.

Default: The -qtune setting determines the optimal default -qcache settings for most typical compilations. -O4, -O5, or -qipa must be specified with the -qcache option.

-qcompact | -qnocompact Reduces code size where possible, at the expense of execution speed. Code size is reduced by inhibiting optimizations that replicate or expand code inline. This option takes effect only if -O2 or higher is also used.

Default: -qnocompact

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata.

-qhot[=<suboption>] | -qnohot Specifies whether or not to perform high-order transformations during optimization. The suboptions are:

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

NAME xlc, xlc++, xlC, cc, c89, c99, xlCcore, xlc++core and related commands - invoke the IBM XL C/C++ compiler.

SYNTAX <invocation-command> [ <option> | <inputfile> ] ...

DESCRIPTION The invocation commands compile C and C++ source files. The commands and their recommended uses are described below.

Invocations Usage (supported standards) _________________________________________________________

xlc, xlc_r, xlc_r4, Compile C source files. xlc_r7, xlc128, xlc128_r, (ANSI C89, ISO C99, xlc128_r4, xlc128_r7 IBM language extensions)

xlc++, xlc++_r, xlc++_r4, Compile C++ source files. xlc++_r7, xlc++128, xlc++128_r, xlc++128_r4, xlc++128_r7, xlC, xlC_r, xlC_r4, xlC_r7, xlC128, xlC128_r, xlC128_r4, xlC128_r7

cc, cc_r, cc_r4, cc_r7, Compile legacy code that cc128, cc128_r, cc128_r4, does not conform to Standard cc128_r7 C. (pre-ANSI C)

c89, c89_r, c89_r4, Compile C source files with c89_r7, c89_128, c89_128_r, strict conformance to the c89_128_r4, c89_128_r7 C89 standard. (ANSI C89)

c99, c99_r, c99_r4, Compile C source files with c99_r7, c99_128, c99_128_r, strict conformance to the c99_128_r4, c99_128_r7 C99 standard. (ISO 99)

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop.

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled.

-qcompact | -qnocompact Reduces code size where possible, at the expense of execution speed. Code size is reduced by inhibiting optimizations that replicate or expand code inline. This option takes effect only if -O2 or higher is also used.

Default: -qnocompact

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata.

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-qspill=<size> Specifies the size of the register allocation spill area in bytes.

Default: -qspill=512

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-W<program>,<options_list> Gives the specified option(s) to the compiler program, <program>. <options_list> is a comma- separated list of one or more options. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = c++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = linkage helper (C++ only) p = Preprocessor

gxlc Accepts GNU C options, maps them to their equivalent XL C option, then invokes xlc.

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified. Default: o norsqrt at -O2 optimization. o rsqrt when when -qnostrict or -O3 or higher optimization level is in effect. single | nosingle Allows single-precision arithmetic instructions to be generated for single- precision floating-point values. All PowerPC processors support single-precision instructions; however, if you wish to preserve the behavior of applications compiled for earlier architectures, in which all floating- point arithmetic was performed in double- precision and then truncated to single- precision, you can use -qfloat=nosingle:norndsngl. This suboption provides computation precision results compatible with those provided by the deprecated options -qarch=com|pwr|pwrx|pwr2|p2sc|601|602|603. Default: single spnans | nospnans Detects signalling NaN on conversion from single-precision to double-precision. Default: nospnans

-qldbl128 | -qnoldbl128 Specifies whether to increase the long double size from 64 to 128 bits. This is equivalent to -qlongdouble.

Default: -qnoldbl128

-qlongdouble | -qnolongdouble Specifies whether to increase the long double size from 64 to 128 bits. This is equivalent to -qldbl128.

Default: -qnolongdouble

-qlonglit | -qnolonglit Makes unsuffixed literals into the long type in 64-bit mode.

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled.

Using -q64 with ppc upgrades the architecture to ppc64. ppc64 Produces object code that will run on any 64- bit PowerPC hardware platform. When compiled in 32-bit mode, the resulting object code may include instructions that are not recognized or behave differently when run on 32-bit PowerPC platforms. ppcgr In 32-bit mode, produces object code containing optional graphics instructions for PowerPC hardware platforms. In 64-bit mode, produces object code containing optional graphics instructions that will run on 64-bit PowerPC platforms, but not on 32-bit-only platforms.

Default: The -qtune setting determines the optimal default -qcache settings for most typical compilations. -O4, -O5, or -qipa must be specified with the -qcache option.

-qcompact | -qnocompact Reduces code size where possible, at the expense of execution speed. Code size is reduced by inhibiting optimizations that replicate or expand code inline. This option takes effect only if -O2 or higher is also used.

Default: -qnocompact

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata.

-qhot[=<suboption>] | -qnohot Specifies whether or not to perform high-order transformations during optimization. The suboptions are:

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = C++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = Linkage helper (C++ only) p = Preprocessor

-qspill=<size> Specifies the size of the register allocation spill area in bytes.

-W<program>,<options_list> Gives the specified option(s) to the compiler program, <program>. <options_list> is a comma- separated list of one or more options. <program> can be one of the following:

a = Assembler b = Low-level optimizer c = Compiler front end C = C++ compiler front end d = Disassembler E = CreateExportList utility f = c++filt utility I = High-level optimizer - compile step L = High-level optimizer - link step l = Linker m = linkage helper (C++ only) p = Preprocessor

gxlc++, gxlC Accepts GNU C/C++ options, maps them to their equivalent XL C++ option,then invokes xlc++.

The main difference between these commands is that they use different default options (which are set in the configuration file /etc/vac.cfg.XX, where XX represents the AIX version). See the Compiler Reference for more information on these invocation commands.

All invocations with a suffix of _r allow for thread-safe compilation. Use these commands to create threaded applications or to link programs that use multi-threading.

These commands also process assembler source files and object files. The compiler calls the link editor to produce a single executable or shared library, unless you specify the compiler options that prevent object files from being linked.

The input file may have any of the following suffixes:

.C, .cpp, .cxx, C++ source file .cc, .cp, .c++

.c C source file

.i Preprocessed C or C++ source file

.a Archive file

.o Object file for ld command

.s Assembler source file

.S Assembler source file that needs preprocessing

.so Shared object file

OPTIONS Compiler options are categorized by their functions and may be used to set the compiler behavior. Options can be flag options or keyword options.

Keyword options are specified in one of the following ways: -q<option> -q<option>=<suboption> -q<option>=<suboption>:<suboption>

Keyword options with no suboptions represent switches that may be either on or off. -qx turns the switch on, and -qnox turns the switch off. For example, -qsource tells the compiler to produce a source listing and -qnosource tells the compiler not to produce a source listing.

Output control options -c Instructs the compiler to pass source files to the compiler only. The compiled source files are not sent to the linker. This option produces an object file, file_name.o, for each valid source file.

-C | -C! Preserves or removes comments in preprocessed output. When -C is used with the -E option, comments are written to standard output; with the -P option, comments are written to an output file. When -C! is in effect, comments are removed.

-E Instructs the compiler to preprocess the source files named in the compiler invocation and creates an output preprocessed source file.

-G Tells the linkage editor to create a shared object enabled for runtime linking.

-M Creates an output file that contains information to be included in a "make" description file. This is equivalent to specifying -qmakedep without a suboption.

-qmakedep[=gcc] Creates an output file that contains targets suitable for inclusion in a description file for the make command that describes the dependencies of the main source file in the compilation. Specifying 'gcc' changes the format of the generated dependency file. Specifying -qmakedep without 'gcc' is equivalent to specifying -M.

-MF<path> Specifies the target for the output generated by the -qmakedep or -M options, where <path> can be a full directory path or file name. Note that "-MF <path>" (with a space before the argument) is also acceptable. This option only has effect when specified with -qmakedep or -M.

(C)-qmkshrobj, (C++)-qmkshrobj[=<priority>] Creates a shared object from the generated object files. The optional number specifies the priority level for initialization of all static objects in the file. <priority> may be any number from -214782623 (highest priority-initialized first) to 214783647 (lowest priority-initialized last). If no priority is specified, the default priority of 0 is used. The priority is not used when linking shared objects (using the xlc command) written in C. Specifying -qmkshrobj implies -qpic. See related options, -e <name> and -o <path>.

-o <path> Specifies an output location for the object, assembler, or executable files created by the compiler. When the -o option is used during compiler invocation, <path> can be the name of either a file or a directory.

Default: -o a.out

-P Preprocesses the C or C++ source files named in the compiler invocation and creates an output preprocessed source file for each input source file. The preprocessed output file has the same name as the output file, with a .i suffix.

-S Generates an assembler language file (.s) for each source file. The resulting .s files can be assembled to produce object .o files or an executable file (a.out).

Input control options -+ (C++) Compiles any file, <file_name.nnn>, as a C++ language file, where <nnn> is any suffix other than .a, .so, .o, .s, or .S. This option is equivalent to the -qsourcetype=c++ option and should not be used together with the -qsourcetype option.

-qcinc=<directory_path> | -qnocinc (C++) Instructs the compiler to place an extern "C" { } wrapper around the contents of an include file, where <directory_path> is the location of that include file.

Default: -qnocinc

-I<directory_path> Specifies an additional search path for include file names that do not specify an absolute path.

Default: The following directories are searched, in the following order, after any paths that are specified by the -I option: 1) The current directory. 2) The directory where the source file is located. 3) /usr/include.

-qidirfirst | -qnoidirfirst Specifies the search order for files included with the #include "<file_name>" directive. Use -qidirfirst with the -I option. If -qidirfirst is specified, the directories specified by the -I<directory_path> option are searched before the directory in which the current file resides.

Default: -qnoidirfirst

-qinclude=<file_path> Specifies additional header files that are included before the first line of a source file in a compilation unit and ahead of any headers which may be specified by an #include statement on the first line of the source file.

-qsourcetype=<type> Determines whether to treat all recognized source files as if they are of the source type specified by <type> (regardless of file name suffix), or whether to use the file name suffix to determine the programming language. Note that the option only affects files that are specified on the command line following the option, but not those that precede the option. The -qsourcetype option should not be used together with the -+ option. The suboptions are:

default The compiler assumes that the programming language of a source file will be implied by its file name suffix. c The compiler compiles all source files following this option as if they are C language source files. assembler The compiler compiles all source files following this option as if they are assembler language source files. assembler-with-cpp The compiler compiles all source files following this option as if they are assembler language source files that need preprocessing.

Default: -qsourcetype=default

-qstdinc | -qnostdinc Specifies whether the standard directories are searched for files included by the #include <file_name> and #include "file_name" directives. The -qnostdinc option excludes the standard include directories from the search path.

Default: -qstdinc

Language element control options -qaltivec | -qnoaltivec Instructs the compiler to support vector data types and operators and is accepted when the architecture specified by the -qarch option supports vector instructions and -qenablevmx is enabled.

Default: -qnoaltivec

-qasm[=<sub>] | -qnoasm[=<sub>] Controls the interpretation of, and subsequent generation of code for, asm statements. In (C), <sub> can only be 'gcc'. In (C++), <sub> can be: gcc Interprets asm statements using GCC syntax. stdcpp Interprets asm statements using stdcpp syntax.

Default: (C++) -qnoasm=stdcpp in compat366 or strict98 modes, and -qasm=gcc otherwise. (C) -qasm=gcc

-qcpluscmt | -qnocpluscmt (C) Permits the usage of "//" to introduce a comment that lasts until the end of the current source line, as in C++.

Default: o -qcpluscmt when you invoke the compiler with xlc, xlc_r, cc, or cc_r, or when -qlanglvl is set to stdc99 or extc99. o -qnocpluscmt otherwise.

-D<name>[=[<def>]] Defines <name> as in the #define directive. <def> is an optional definition or value assigned to <name>. Specifying -D<name>= (with no <def>) is equivalent to #define <name>; specifying -D<name> is equivalent to #define <name> 1.

-qdbcs | -qnodbcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qmbcs.

Default: -qnodbcs

-qdfp | -qnodfp Enables compiler support for decimal floating-point types and literals.

Default: -qnodpf

-qdigraph | -qnodigraph Allows usage of digraph key combinations or keywords to represent characters not found on some keyboards.

Default: (C) -qdigraph when -qlanglvl is extc89, extended, extc99 or stdc99, and -qnodigraph otherwise. (C++) -qdigraph

-qdollar | -qnodollar Allows the '$' symbol to be used in the names of identifiers. When -qdollar is in effect, the dollar symbol '$' in an identifier is treated as a base character. If the options -qnodollar and -qlanglvl=ucs are both enabled, the dollar symbol is treated as an extended character.

Default: -qnodollar

-qignprag=<option> Instructs the compiler to ignore certain pragma statements. The options are:

disjoint Ignores all #pragma disjoint directives in the source file. isolated_call Ignores all #pragma isolated_call directives in the source file. all Ignores all #pragma isolated_call directives and #pragma disjoint directives in the source file. omp Ignores all OpenMP parallel processing directives in the source file. ibm (C) Ignores all #pragma ibm snapshot directives and all IBM SMP directives in the source file.

-qkeyword=<keyword> | -qnokeyword=<keyword> Controls whether the specified name is treated as a keyword or as an identifier whenever it appears in a program source. By default, all the built-in keywords defined in the C and C++ language standards are reserved as keywords. You cannot add keywords to the language with this option. However, you can use -qnokeyword=<keyword> to disable built-in keywords, and use -qkeyword=<keyword> to reinstate those keywords.

(C) This option can also be used with the following C keywords: restrict, typeof, asm and inline. (C++) This option can be used with all C++ built-in keywords.

-qlanglvl=<suboptions_list> Selects the language level and language options for the compilation. <suboptions_list> is a colon- separated list of suboptions.

(C) For C language programs, <suboptions_list> is {classic|extended|saa|saa12|stdc89|stdc99|extc89|extc99}:{ucs|noucs}. classic Allows the compilation of non-stdc89 programs, and conforms closely to the K&R level preprocessor. extended Provides compatibility with the RT compiler and classic. This language level is based on C89. saa Compilation conforms to the current SAA(R) C CPI language definition. This is currently SAA C Level 2. saal2 Compilation conforms to the SAA C Level 2 CPI language definition, with some exceptions. stdc89 Compilation conforms to the ANSI C89 standard, also known as ISO C90. stdc99 Compilation conforms to the ISO C99 standard. extc89 Compilation conforms to the ANSI C89 standard, and accepts implementation-specific language extensions. extc99 Compilation conforms to the ISO C99 standard, and accepts implementation-specific language extensions. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in program source code. Default: o -qlanglvl=ucs under language levels stdc99 and extc99. o -qlanglvl=noucs for all other language levels.

(C++) The suboptions for C++ language programs are: compat366 Compilation conforms to some, but not all, IBM C and C++ Compilers V3.6 features. extended Compilation is based on the strict98, with some differences to accommodate extended language features. strict98 Compilation conforms to the ISO C++ standard for C++ programs. anonstruct | noanonstruct This suboption controls whether anonymous structs and anonymous classes are allowed in your C++ source. By default, the compiler allows anonymous structs. anonunion | noanonunion This suboption controls what members are allowed in anonymous unions. When this suboption is set to anonunion, anonymous unions can have members of all types that standard C++ allows in non-anonymous unions. ansifor | noansifor This suboption controls whether scope rules defined in the C++ standard apply to names declared in for-init statements. By default, standard C++ rules are used. ansisinit | noansisinit This suboption can be used to select between old (v3.6 or earlier) and current (v5.0 or later) compiler object compatibility. c99__func__ | noc99__func__ This suboption instructs the compiler to recognize the C99 __func__ identifier. The c99__func__ suboption is enabled by default when -qlanglvl=extended is enabled. It can be enabled for any language level by specifying -qlanglvl=c99__func__, or disabled by specifying -qlanglvl=noc99__func__. c99complex | noc99complex This suboption instructs the compiler to recognize C99 complex data types and related keywords. It is set by default for -qlanglvl=extended. c99complexheader | noc99complexheader This suboption instructs the compiler to use the C99 complex.h header file. c99compoundliteral | noc99compoundliteral This suboption instructs the compiler to support the C99 compound literal feature. It is set by default for -qlanglvl=extended. c99hexfloat | noc99hexfloat This suboption enables support for C99-style hexadecimal floating constants in C++ applications. It is on by default for -qlanglvl=extended. c99vla | noc99vla When c99vla is enabled, the compiler will support the use of C99-type variable length arrays in your C++ applications. It is set by default for -qlanglvl=extended. compatzea | nocompatzea The -qlanglvl=compatzea option is a compatibility option that lets you continue to use a zero extent array with dimension of 1. Default: -qlanglvl=nocompatzea Specifying -qlanglvl=compatzea has effect only if -qlanglvl=zeroextarray is also enabled. dependentbaselookup | nodependentbaselookup Provides the ability to specify compilation in conformance with issue 213 of TC1 of the C++ standard. Default: -qlanglvl=dependentbaselookup gnu_assert | nognu_assert Enables or disables support for the following GNU C system identification assertions: '#assert', '#unassert', '#cpu', '#machine', '#system'. gnu_complex | nognu_complex This suboption instructs the compiler to recognize GNU complex data types and related keywords. gnu_computedgoto | nognu_computedgoto Enables support for computed gotos. This suboption is enabled for -qlanglvl=extended. gnu_explicitregvar | nognu_explicitregvar (C) Allows you to control whether the compiler accepts and ignores the specification of explicit registers for variables. gnu_externtemplate | nognu_externtemplate This suboption enables or disables extern template instantiations. Default: gnu_externtemplate is enabled by default when compiling to the extended language level. gnu_include_next | nognu_include_next Enables or disables support for the GNU C #include_next preprocessor directive. Default: gnu_include_next is enabled by default for -qlanglvl=extended. gnu_labelvalue | nognu_labelvalue Enables or disables support for labels as values. Default: gnu_labelvalue is enabled by default for -qlanglvl=extended. gnu_locallabel | nognu_locallabel Enables or disables support for locally- declared labels. gnu_membernamereuse | nognu_membernamereuse Enables or disables reusing a template name in a member list as a typedef. gnu_suffixij | nognu_suffixij Enables or disables support for GCC style complex numbers. If gnu_suffixij is specified, a complex number can be ended with suffix i/I or j/J. Default: gnu_suffixij is enabled by default for -qlanglvl=extended. gnu_varargmacros | nognu_varargmacros This option is similar to -qlanglvl=varargmacros. For the list of the main differences, refer to the Compiler Reference. Default: gnu_varargmacros is set by default for -qlanglvl=extended. gnu_warning | nognu_warning Enables or disables support for the GNU C #warning preprocessor directive. illptom | noillptom This suboption controls what expressions can be used to form pointers to members. C/C++ can accept some forms that are in common use, but do not conform to the C++ standard. The compiler allows these forms by default. implicitint | noimplicitint This suboption controls whether the compiler will accept missing or partially specified types as implicitly specifying 'int'. This is no longer accepted in the standard but may exist in legacy code. With the suboption set to noimplicitint, all types must be fully specified. With the suboption set to implicitint, a function declaration at namespace scope or in a member list will implicitly be declared to return int. newexcp | nonewexcp This suboption determines whether or not the C++ new operator throws an exception. If the -qlanglvl=newexcp option is specified, the standard exception std::bad_alloc is thrown when the requested memory allocation fails. This option does not apply to the nothrow versions of the new operator. The standard implementation of the new operators fully support exceptions. For compatibility with previous versions of VisualAge C++, these operators return 0 by default. offsetnonpod | nooffsetnonpod This suboption controls whether the offsetof macro can be applied to classes that are not data-only. By default, the compiler allows offsetof to be used with non-POD classes. olddigraph | noolddigraph This option controls whether old-style digraphs are allowed in your C++ source. It applies only when -qdigraph is also set. By default, the compiler supports only the digraphs specified in the C++ standard. oldfriend | nooldfriend This option controls whether friend declarations that name classes without elaborated class names are treated as C++ errors. By default, the compiler lets you declare a friend class without elaborating the name of the class with the keyword class. oldmath | nooldmath This suboption controls which versions of math function declarations in <math.h> are included when you specify math.h as an included or primary source file. By default, the new standard math functions are used. Build with -qlanglvl=nooldmath for strict compliance with the C++ standard. For compatibility with modules that were built with earlier versions of VisualAge C++ and predecessor products, you may need to build with -qlanglvl=oldmath. oldtempacc | nooldtempacc This suboption controls whether access to a copy constructor to create a temporary object is always checked, even if creation of the temporary object is avoided. By default, the compiler suppresses the access checking. oldtmplalign | nooldtmplalign Controls whether alignment rules specified for nested templates are ignored. When the default, -qlanglvl=nooldtmplalign, is in effect, these alignment rules are not ignored. Specify -qlanglvl=oldtmplalign for compatibility with VisualAge C++ 4.0 and predecessor products. oldtmplspec | nooldtmplspec This suboption controls whether template specializations that do not conform to the C++ standard are allowed. By default, the compiler allows these old specializations (-qlanglvl=nooldtmplspec). redefmac | noredefmac Specifies whether a macro can be redefined without a prior #undef or undefine() statement. trailenum | notrailenum This suboption controls whether trailing commas are allowed in enum declarations. By default, the compiler allows one or more trailing commas at the end of the enumerator list. typedefclass | notypedefclass This suboption provides backwards compatibility with previous versions of VisualAge C++ and predecessor products. ucs | noucs This suboption controls whether Unicode characters are allowed in identifiers, string literals and character literals in C++ sources. Default: -qlanglvl=noucs varargmacros | novarargmacros This C99 feature allows the use of a variable argument list in function-like macros in your C++ applications. zeroextarray | nozeroextarray This suboption controls whether zero-extent arrays are allowed as the last non-static data member in a class definition. By default, the compiler allows arrays with zero elements.

The default depends on the invocation command used:

Command Default _____________________________________________

xlC/xlc++ extended xlc extc99 cc extended c89 stdc89 c99 stdc99

-qlonglong | -qnolonglong Allows IBM-style long long integers. This option cannot be used with -qlanglvl=stdc99 or -qlanglvl=extc99.

Default: o -qlonglong when compiling with xlc, xlc++, xlC or cc. o -qnolonglong when compiling with c89 or c99.

-qmacpstr | -qnomacpstr Converts Pascal string literals into null- terminated strings where the first byte contains the length of the string.

Default: -qnomacpstr

-qmbcs | -qnombcs Specifies that string literals and comments can contain multi-byte characters. This is equivalent to -qdbcs.

Default: -qnombcs

-qstaticinline | -qnostaticinline (C++) Controls whether inline functions are treated as static or extern. Specifying -qnostaticinline means the inline functions are treated as having extern linkage.

Default: -qnostaticinline

-qtabsize=<size> Changes the length of tabs as perceived by the compiler, where <size> is the number of character spaces representing a tab in the source program.

Default: -qtabsize=8

-qtrigraph | -qnotrigraph Allows trigraph key combinations to represent characters not found on some keyboards.

Default: -qtrigraph

However, if -qlanglvl=classic is enabled or implied, the trigraphs are not recognized by default.

-U<name> Undefines the identifier <name> defined by the compiler or by the -D<name> option.

-qutf | -qnoutf Enables recognition of UTF literal syntax.

Default: o (C) -qnoutf o (C++) -qutf for all language levels except -qlanglvl=strict98 o (C++) -qnoutf when -qlanglvl=strict98 is in effect

Template control options (C++ only) -qtempinc[=<directory_path>] | -qnotempinc (C++) Generates separate template include files for template functions and class declarations, and places these files in a directory which can be optionally specified.

Default: -qnotempinc

-qtemplatedepth=<number> (C++) Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler. <number> can be a value between 1 and INT_MAX.

Default: -qtemplatedepth=300

-qtemplaterecompile | -qnotemplaterecompile (C++) Helps manage dependencies between compilation units that have been compiled using the -qtemplateregistry compiler option.

Default: -qnotemplaterecompile

-qtemplateregistry[=<filename>] | -qnotemplateregistry (C++) Maintains records of all templates as they are encountered in the source and ensures that only one instantiation of each template is made.

Default: -qnotemplateregistry

-qtempmax=<number> (C++) Specifies the maximum number of template include files to be generated by the -qtempinc option for each header file.

Default: -qtempmax=1

-qtmplinst=<suboption> (C++) Allows you to manage implicit template instantiations. <suboption> is one of the following:

none Instantiates only the inline functions. If this is specified, -qtempinc and -qtemplateregistry are ignored. noinline Suppresses all implicit instantiations. auto Handles the implicit instantiations according to the -qtempinc and -qtemplateregistry options. If both options are off, then implicit instantiations are always performed. always Always perform implicit instantiations. This will ignore the -qtempinc and -qtemplateregistry options.

Default: -qtmplinst=auto

-qtmplparse=<option> (C++) Controls whether parsing and semantic checking are applied to template definition implementations or only to template instantiations. The compiler has the option to produce warning or error messages. The suboptions are:

no Does not parse, to reduce the number of errors issued in code written for previous versions of the compiler. warn Parses template definitions and issues warning messages for semantic errors. error Treats problems in template definitions as errors, even if the template is not instantiated.

Default: -qtmplparse=no

Floating-point and integer control options -qbitfields={signed|unsigned} Specifies whether bit fields will be signed or unsigned.

Default: -qbitfields=unsigned

-qchars={signed|unsigned} Specifies whether the data type char will be signed or unsigned.

Default: -qchars=unsigned

-qenum=<suboption> Specifies the amount of storage occupied by enumerations, where <suboption> can be:

small Specifies that enumerations occupy the smallest amount of space (1, 2, 4, or 8 bytes) that can accurately represent the range of values in the enumeration. Signage is unsigned, unless the range of values includes negative values. int Specifies that enumerations occupy 4 bytes and are represented by int. intlong Specifies that enumerations occupy 8 bytes of storage if the range of values in the enumeration exceeds the limit for int. Otherwise, the enumerations occupy 4 bytes of storage and are represented by int. 1 Specifies that enumerations occupy 1 byte. Type is signed or unsigned char. 2 Specifies that enumerations occupy 2 bytes. Type is signed or unsigned short. 4 Specifies that enumerations occupy 4 bytes. Type is signed or unsigned int. 8 Specifies that enumerations occupy 8 bytes. Type is signed or unsigned long long in 32-bit mode, and signed or unsigned long in 64-bit mode.

Default: -qenum=intlong

-qfloat=<suboptions_list> Specifies various floating-point suboptions. This provides different strategies for speeding up or improving the accuracy of floating-point calculations. <suboptions_list> is a colon- separated list of one or more of the following:

dfpemulate | nodfpemulate Specifies whether decimal floating-point computations are implemented in hardware instructions or emulated in software by calls to library functions. -qdfp must be enabled for either suboption to have any effect. nodfpemulate is only valid on a system that supports decimal floating-point instructions; that is, on AIX 5.3 and higher, and with -qarch=pwr6 in effect. dfpemulate is required for all other -qarch values. Default: dfpemulate fenv | nofenv Specifies whether the code depends on the hardware environment and whether to suppress optimizations that could cause unexpected results due to this dependency. When nofenv is in effect, the compiler assumes that the program does not depend on the hardware environment, and that aggressive compiler optimizations that change the sequence of floating-point operations are allowed to be performed. When fenv is in effect, such optimizations are suppressed. Default: nofenv fltint | nofltint Speeds up floating-point-to-integer conversions by using faster inline code that does not check for overflows. -qfloat=nofltint checks floating-point-to-integer conversions for out-of-range values. Default: o nofltint at -O2 optimization. o fltint when -qnostrict or -O3 or higher optimization level is in effect. fold | nofold Specifies that constant floating-point expressions are to be evaluated at compile time rather than at run time. Default: fold hscmplx | nohscmplx Speeds up operations involving complex division and complex absolute value. This suboption, which provides a subset of the optimizations of the hsflt suboption, is preferred for complex calculations. Default: nohscmplx hsflt | nohsflt The hsflt option speeds up calculations by truncating instead of rounding computed values to single precision before storing and on conversions from floating-point to integer. The nohsflt suboption specifies that single- precision expressions are rounded after expression evaluation and that floating- point-to-integer conversions are to be checked for out-of-range values. Default: nohsflt hssngl | nohssngl The hssngl option specifies that single- precision expressions are rounded only when the results are stored into float memory locations. The nohssngl option specifies that single-precision expressions are rounded after expression evaluation. Using hssngl can improve runtime performance and is safer than using -qfloat=hsflt. Default: nohssngl maf | nomaf Makes floating-point calculations faster and more accurate by using floating-point multiply-add instructions where appropriate. Default: maf nans | nonans Generates extra instructions to detect signalling NaN when converting from single- precision to double-precision at run time. The option nonans specifies that this conversion need not be detected. Default: nonans relax | norelax Relaxes the strict IEEE-conformance slightly for greater speed, typically by removing some trivial, floating-point arithmetic operations, such as adds and subtracts involving a zero on the right. Default: norelax rndsngl | norndsngl Specifies that the result of each single- precision (float) operation is to be rounded to single precision. -qfloat=norndsngl specifies that rounding to single-precision happens only after full expressions have been evaluated. Default: rndsngl rngchk | norngchk Specifying norngchk instructs the compiler to skip range checking, allowing for increased performance where division and sqrt operations are performed repeatedly within a loop. When rngchk is specified, range checking is performed for input arguments for software divide and inlined sqrt operations. When -qstrict is active, the setting of this option is forced to -qfloat=rngchk. When -qnostrict is active, the setting of this option is -qfloat=norngchk unless the -qfloat=rngchk option is explicitly set by the user. Default: rngchk rrm | norrm Prevents floating-point optimizations that are incompatible with runtime rounding to plus and minus infinity modes. Default: norrm rsqrt | norsqrt Specifies whether a sequence of code that involves division by the result of a square root can be replaced by calculating the reciprocal of the square root and multiplying. Allowing this replacement produces code that runs faster. -qfloat=rsqrt has no effect unless -qignerrno is also specified. Default: o norsqrt at -O2 optimization. o rsqrt when when -qnostrict or -O3 or higher optimization level is in effect. single | nosingle Allows single-precision arithmetic instructions to be generated for single- precision floating-point values. All PowerPC processors support single-precision instructions; however, if you wish to preserve the behavior of applications compiled for earlier architectures, in which all floating- point arithmetic was performed in double- precision and then truncated to single- precision, you can use -qfloat=nosingle:norndsngl. This suboption provides computation precision results compatible with those provided by the deprecated options -qarch=com|pwr|pwrx|pwr2|p2sc|601|602|603. Default: single spnans | nospnans Detects signalling NaN on conversion from single-precision to double-precision. Default: nospnans

-qldbl128 | -qnoldbl128 Specifies whether to increase the long double size from 64 to 128 bits. This is equivalent to -qlongdouble.

Default: -qnoldbl128

-qlongdouble | -qnolongdouble Specifies whether to increase the long double size from 64 to 128 bits. This is equivalent to -qldbl128.

Default: -qnolongdouble

-qlonglit | -qnolonglit Makes unsuffixed literals into the long type in 64-bit mode.

Default: -qnolonglit

-y<rounding_mode> Specifies the compile-time rounding mode of constant floating-point expressions.

For binary floating-point types, <rounding_mode> is one of the following: m = round toward minus infinity n = round to the nearest representable number, ties to even p = round toward plus infinity z = round toward zero

Default: -yn

For decimal floating-point types, <rounding_mode> is one of the following: di = round toward infinities (away from zero) dm = round toward minus infinity dn = round to the nearest representable number, ties to even dna = round to the nearest representable number, ties away from zero dnz = round to the nearest representable number, ties toward zero dp = round toward plus infinity dz = round toward zero

Default: -ydn

Object code control options -q32, -q64 Selects either 32-bit or 64-bit compilation mode. Use the -q32 and -q64 options, along with the -qarch and -qtune compiler options, to optimize the output of the compiler to the architecture on which that output will be used.

Default: -q32

-qalloca (C) Substitutes inline code for calls to function alloca, as if #pragma alloca directives were in the source code.

-ma (C) Substitutes inline code for calls to function alloca.

-qeh[={v5|v6}] | -qnoeh (C++) Controls whether exception handling is enabled in the module being compiled.

v5 Instructs the compiler to generate exception- handling code that is compatible with VisualAge C++ V5.0. v6 Instructs the compiler to generate new exception-handling code, compatible with VisualAge C++ V6.0, that correctly handles try-catch blocks nested within other catch blocks.

-qlistopt | -qnolistopt Produces a compiler listing that displays all the options that were in effect when the compiler was invoked.

Default: -qnolistopt

-qphsinfo | -qnophsinfo Reports the time taken in each compilation phase. Phase information is sent to standard output.

Default: -qaggrcopy=nooverlap

-qalias=<suboptions_list> Specifies the aliasing assertions to be applied to your compilation unit. <suboptions_list> is a colon-separated list of the following options:

addrtaken | noaddrtaken Variables are disjoint from pointers unless their address is taken. allptrs | noallptrs Pointers are never aliased if allptrs is specified, but may be aliased if noallptrs is specified. -qalias=allptrs implies -qalias=typeptr. ansi | noansi If ansi is specified, type-based aliasing is used during optimization, which restricts the lvalues that can be safely used to access a data object. This option has no effect unless you also specify the -O option. Specifying -qalias=noansi turns off type-based aliasing completely. global | noglobal When global is in effect, type-based aliasing rules are enabled during IPA link-time optimization across compilation units. Both -qipa and -qalias=ansi must be enabled for -qalias=global to have an effect. Specifying noglobal disables type-based aliasing rules across compilation units. restrict | norestrict When restrict is in effect, optimizations for pointers qualified with the restrict keyword are enabled. Specifying norestrict disables optimizations for restrict-qualified pointers. -qalias=restrict is independent from other -qalias suboptions. typeptr | notypeptr Pointers to different types are never aliased if typeptr is specified, but may be aliased if notypeptr is specified.

Using -q64 with ppc upgrades the architecture to ppc64. ppc64 Produces object code that will run on any 64- bit PowerPC hardware platform. When compiled in 32-bit mode, the resulting object code may include instructions that are not recognized or behave differently when run on 32-bit PowerPC platforms. ppcgr In 32-bit mode, produces object code containing optional graphics instructions for PowerPC hardware platforms. In 64-bit mode, produces object code containing optional graphics instructions that will run on 64-bit PowerPC platforms, but not on 32-bit-only platforms.

Default: The -qtune setting determines the optimal default -qcache settings for most typical compilations. -O4, -O5, or -qipa must be specified with the -qcache option.

-qcompact | -qnocompact Reduces code size where possible, at the expense of execution speed. Code size is reduced by inhibiting optimizations that replicate or expand code inline. This option takes effect only if -O2 or higher is also used.

Default: -qnocompact

-qdataimported[=<variable_names>] Specifies variables that the compiler can assume are imported. <variable_names> is a colon-separated list of variables. Specifying -qdataimported without <variable_names> instructs the compiler to assume that all variables are imported. This is equivalent to specifying -qnotocdata. (C++) Variable names must be specified using their mangled names.

-qdatalocal[=<variable_names>] Specifies variables that the compiler can assume are local. <variable_names> is a colon-separated list of variables. Specifying -qdatalocal with no variables instructs the compiler to assume that all variables are local. This is equivalent to specifying -qtocdata.

Default: -qnofdpr

-qhot[=<suboption>] | -qnohot Specifies whether or not to perform high-order transformations during optimization. The suboptions are:

arraypad[=<number>] | noarraypad When <number> is specified, the compiler will pad every array in the code. The pad amount must be a positive integer value. Otherwise, the compiler will pad any arrays where it infers that there may be a benefit. level={0|1} Specifies the level of high-order transformation to perform during compilation. 0 The compiler performs a subset of the high-order transformations. Some of these include early distribution, loop interchange, and loop tiling, as examples. Optimization level -O3 implies -qhot=level=0. 1 At level=1, full high-order transformation is performed. -qhot=level=1 is equivalent to -qhot and the compiler options that imply -qhot also imply -qhot=level=1, unless -qhot=level=0 is explicitly specified. simd | nosimd Converts certain operations in a loop that apply to successive elements of an array into a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. If you specify -qhot=nosimd, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with vector instructions. To enable -qhot=simd, you must specify an architecture that supports vector instructions. vector | novector When specified with -qnostrict and -qignerrno, or an optimization level of -O3 or higher (otherwise -qhot=vector has no effect), the compiler converts certain operations in a loop that apply to successive elements of an array into a call to a routine in the Mathematical Acceleration Subsystem (MASS) library, part of the libxlopt.a library. If you specify -qhot=novector, the compiler performs optimizations on loops and arrays, but avoids replacing certain code with calls to vector library routines.

Specifying -qhot without suboptions implies -qhot=nosimd, -qhot=noarraypad, -qhot=vector and -qhot=level=1. The -qhot option is also implied by -qsmp, -O4, and -O5.

Default: -qnohot

-qignerrno | -qnoignerrno Allows the compiler to perform optimizations that assume errno is not modified by system calls.

Default: -qnoignerrno

-qipa[=<suboptions_list>] | -qnoipa Turns on or customizes a class of optimizations known as interprocedural analysis (IPA). <suboptions_list> is a colon-separated list of the following suboptions:

clonearch=<arch_name> | noclonearch Specifies the architectures for which multiple versions of the same instruction set are produced, where <arch_name> is a comma- separated list of architecture names. Use this suboption if you require optimal performance on multiple differing machines running the same copy of your application. cloneproc=<function_name> | nocloneproc=<function_name> Specifies the name of the functions to clone for the architectures specified by the clonearch suboption, where <function_name> is a comma-separated list of function names. exits=<procedures> Specifies names of functions which represent program exits. <procedures> is a comma- separated list of procedures. infrequentlabel=<procedures> Specifies a comma-separated list of user- defined labels that are likely to be called infrequently during a program run. inline[=<suboption>] Specifying 'inline' with no suboption asserts that all appropriate procedures will be inlined. <suboption> can be one of the following: auto|noauto Enables or disables automatic function inlining by the high-level optimizer. When -qipa=inline=auto is in effect, the compiler considers all functions that are under the maximum size limit (see below) for inlining. When -qipa=inline=noauto is in effect, only procedures listed in the <procedures> suboption are considered for inlining. <procedures> Specifies a comma-separated list of procedures to attempt to inline. limit=<num> Specifies a limit on the size of a calling function after inlining. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 8192 by default. threshold=<num> Specifies the upper size limit on procedures to inline. This only takes effect when inline=auto is on. If you do not specify a value for <num>, <num> is 1024 by default. Default: auto noinline[=<procedures>] Specifies a comma-separated list of procedures which are not to be inlined. Specifying noinline without <procedures>, asserts that no procedures are to be inlined. isolated=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and do not directly refer to any global variable. level=<level> Determines the amount of IPA analysis and optimization performed, where <level> can be equal to: 0 Performs only minimal interprocedural analysis and optimization. 1 Turns on inlining, limited alias analysis, and limited call-site tailoring. 2 Full interprocedural data flow and alias analysis. Default: 1 list[={<file_name>|short|long}] Specifies an output listing file name during the link phase. The default name is "a.lst". Specifying 'long' or 'short' can be used to request more or less information in the listing file to determine which listing sections will be included. Default: short lowfreq=<procedures> Specifies a comma-separated list of procedures that are likely to be called infrequently during the course of a typical program run. malloc16 | nomalloc16 Informs the compiler that the dynamic memory allocation routines will return 16-byte aligned memory addresses. The compiler can then optimize the code based on that assertion. Default: -qipa=malloc16 missing={unknown|safe|isolated|pure} Specifies the default assumption for procedures not compiled with -qipa. unknown Greatly restricts the amount of interprocedural optimization for calls to unknown functions. safe Functions which do not indirectly call a visible (not missing) function either through direct call or function pointer. isolated Functions which do not directly reference global variables accessible to visible functions. pure Functions which are safe and isolated and which do not indirectly alter storage accessible to functions. Default: missing=unknown object | noobject Specifies whether to include standard object code in the object files. Specifying 'noobject' can substantially reduce overall compile time by not generating object code during the first IPA phase. partition={small|medium|large} Specifies the size of program sections that are analyzed together. Larger partitions may produce better analysis but require more storage. Default: partition=medium pure=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that are "isolated", "safe", and do not modify any data objects that are visible to the caller. safe=<procedures> Specifies a comma-separated list of procedures not compiled with -qipa and that do not call any other part of the program. threads[=<suboption>] | nothreads Runs portions of the IPA optimization process during pass 2 in parallel threads, which can speed up the linking process on multi- processor systems. <suboption> can be one of the following: auto | noauto When auto is in effect, the compiler selects a number of threads heuristically based on machine load. When noauto is in effect, the compiler spawns one thread per machine processor. <number> Instructs the compiler to use a specific number of threads. <number> can be any integer value in the range of 1 to 32767. However, <number> is effectively limited to the number of processors available on your system. Specifying threads with no suboptions implies threads=auto. Default: -qipa=threads unknown=<procedures> Specifies a comma-separated list of procedures that are not compiled with -qipa and that may update global variables and dummy arguments and call other parts of the program compiled with -qipa. <file_name> Specifies the name of a file that contains suboption information in a special format.

Regular expressions are supported when specifying procedure names for these suboptions: cloneproc, nocloneproc, exits, inline, noinline, isolated, lowfreq, pure, safe, unknown. (C++) In C++ programs, procedure names must be given in mangled form.

Default: -qnoipa -qipa=inline=auto:level=1:missing=unknown:partition=medium:threads=auto when -O4 is in effect. -qipa=inline=auto:level=2:missing=unknown:partition=medium:threads=auto when -O5 is in effect. -qipa=inline=auto:level=0:missing=unknown:partition=medium:threads=auto when -qpdf1 or -qpdf2 is in effect.

-qisolated_call=<procedures> Informs the compiler that specific functions do not have or rely on side effects, other than those implied by their parameters. <procedures> is a colon-separated list of function names.

-qlargepage | -qnolargepage Indicates that a program, designed to execute in a large page memory environment, can take advantage of large 16 MB pages provided on POWER4 and later systems.

Default: -qnolargepage

-qlibansi | -qnolibansi Assumes that all functions with the name of an ANSI C defined library function are, in fact, the library functions.

Default: -qnolibansi

-qmaxmem=<size> Limits the amount of memory used by certain memory-intensive optimizations to <size> kilobytes. When <size> is -1, the optimizer will use as much memory as needed.

Default: o -qmaxmem=8192 when -O2 level optimization is set. o -qmaxmem=-1 when -O3 level or greater optimization is set.

-qminimaltoc | -qnominimaltoc Avoids Table of Contents (TOC) overflow conditions by placing TOC entries into a separate data section for each object file. By default, the compiler will allocate at least one TOC entry for each unique non-automatic variable reference in your program.

Default: -qnominimaltoc

-O[<level>] Optimizes code at a choice of levels during compilation. This is equivalent to -qoptimize[=<level>]. <level> can be:

0 Performs only quick local optimizations such as constant folding and elimination of local common subexpressions. 2 Performs optimizations that the compiler developers considered the best combination for compilation speed and runtime performance. The optimizations may change from product release to release. 3 Performs some memory and compile-time intensive optimizations in addition to those executed with -O2. The -O3 specific optimizations have the potential to alter the semantics of a program. The compiler guards against these optimizations at -O2 and the option -qstrict is provided at -O3 to turn off these aggressive optimizations. Specifying -O3 implies -qhot=level=0. 4 This option is the same as -O3, but also: o sets the -qarch and -qtune options to the architecture of the compiling machine. o sets the -qcache option most appropriate to the characteristics of the compiling machine. 5 Equivalent to -O4 -qipa=level=2.

Specifying -O with no <level> is equivalent to specifying -O2.

Default: -O0

-qoptimize[=<level>] | -qnooptimize The long form of the -O option. -qoptimize=<level> is equivalent to -O<level>. See the -O option.

Default: -qnooptimize

-p, -pg, -qprofile={-p|-pg} Sets up the object files produced by the compiler for profiling. -pg is like -p, but it produces more extensive statistics.

-qpdf1[=pdfname=<file_path] | -qnopdf1 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf1 produces an object that is instrumented to collect runtime execution information. This is phase 1 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf1

-qpdf2[=pdfname=<file_path>] | -qnopdf2 Tunes optimizations through profile-directed feedback (PDF), where results from sample program execution are used to improve optimization near conditional branches and in frequently executed code sections. Used with a minimum optimization level of -O2, -qpdf2 tunes application performance using the data generated by running a program compiled with -qpdf1. This is phase 2 of the profile-directed feedback optimization process.

pdfname=<file_path> Specifies the location and name of the profile data file containing the PDF profiling information. Default: If you do not specify <file_path>, the default file name is ._pdf and the file is saved in the current working directory, or in the directory named by the PDFDIR environment variable, if it is set.

Default: -qnopdf2

-qprefetch | -qnoprefetch Enables generation of prefetching instructions such as dcbt and dcbz in compiled code.

Default: -qprefetch

-qprocimported[=<procedures>] | -qnoprocimported Specifies functions that the compiler can assume are imported. Imported functions are dynamically bound with a shared portion of a library. Code generated for calls to functions marked as imported may be larger, but is faster than the default code sequence generated for functions marked as unknown. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qproclocal[=<procedures>] | -qnoproclocal Specifies functions that the compiler can assume are local. Local functions are statically bound with the functions that call them; smaller, faster code is generated for calls to such functions. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-qprocunknown[=<procedures>] | -qnoprocunknown Specifies functions that the compiler can assume are unknown. Unknown functions are resolved to either statically or dynamically bound objects during linking. <procedures> is a colon-separated list of function identifiers. (C++) In C++ programs, function names must be specified using their mangled names.

-Q[<suboption>] (C++) Instructs the compiler to try to inline functions. Inlining is performed if possible but, depending on which optimizations are performed, some functions might not be inlined.

(C) Specifies which specific functions the compiler should attempt to inline. You must specify at least an optimization level of -O2 for inlining to take effect with -Q. To turn on inline expansion for calls to procedures in different scopes, you must also use the -qipa=inline.

(C++) In the C++ language, this option can take the form:

-Q Compiler inlines all functions that it can. -Q! Compiler does not inline any functions.

(C) In the C language, this option can take the form:

-Q Attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to the setting of any of the suboptions to the -Q option. If -Q is specified last, all functions are inlined. -Q! Does not inline any functions. If -Q! is specified last, no functions are inlined. -Q-<names> Does not inline functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. The option implies -Q. -Q+<names> Attempts to inline the functions listed in <names>, where <names> is a colon-separated list. All other appropriate functions are inlined. -Q=<threshold> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <threshold> for the function to be inlined.

Default: -Q!

-qinline[<suboption>] | -qnoinline Specifies whether to attempt to inline functions instead of generating calls to a function.

(C++) In C++, you cannot specify any suboptions. -qinline specifies that all appropriate functions should be inlined, and -qnoinline specifies that no functions should be inlined.

(C) In C, this option can take the following forms:

-qinline The compiler attempts to inline all appropriate functions with 20 executable source statements or fewer, subject to any other settings of the suboptions to the -qinline option. -qinline+<procedures> Attempts to inline the functions listed in <procedures> and any other appropriate functions, where <procedures> is a colon- separated list. -qinline-<procedures> Specifies that functions listed in <procedures> do not get inlined, where <procedures> is a colon-separated list. -qnoinline Does not inline any functions. -qinline=threshold=<num> Sets a size limit on the functions to be inlined. The number of executable statements must be less than or equal to <num> for the function to be inlined. <num> must be a positive integer.

Default: The default is to treat inline specifications as a hint to the compiler, and the result depends on other options that you select. If you specify the -g option (to generate debug information), inlining may be affected.

-qshowpdf | -qnoshowpdf Used with -qpdf1 and a minimum optimization level of -O2 to add additional call and block count profiling information to an executable.

Default: -qnoshowpdf

-qsmallstack | -qnosmallstack Reduces the size of the stack frame. This option is only valid when used together with IPA (-qipa, -O4, -O5 compiler options).

Default: -qnosmallstack

-qsmp[=<suboptions_list>] | -qnosmp Enables parallelization of program code. <suboptions_list> is a colon-separated list of one or more of the following suboptions:

auto | noauto Enables automatic parallelization and optimization. If noauto is specified, automatic parallelization of program code is disabled; only program code explicitly parallelized with OpenMP directives is optimized. Default: auto nested_par | nonested_par If nested_par is specified, prescriptive nested parallel constructs are parallelized by the compiler. Default: nonested_par omp | noomp Enables strict OpenMP compliance. Only OpenMP parallelization pragmas are recognized. Default: noomp opt | noopt Enables automatic parallelization but disables optimization of parallelized program code. If noopt is specified, optimization of parallelized program code is disabled. Default: opt rec_locks | norec_locks Specifies whether to use recursive locks. Default: norec_locks schedule=<type> Specifies what kinds of scheduling algorithms and chunking are used for loops to which no other scheduling algorithm has been explicitly assigned in the source code. <type> can be: o affinity[=<num>] o dynamic[=<num>] o guided[=<num>] o runtime o static[=<num>], where <num> is the number of loop iterations. Default: schedule=runtime stackcheck | nostackcheck Causes the compiler to check for stack overflow by slave threads at run time, and issue a warning if the remaining stack size is less than the number of bytes specified by the stackcheck option of the XLSMPOPTS environment variable. This suboption is intended for debugging purposes, and only takes effect when XLSMPOPTS=stackcheck is also set. Default: nostackcheck threshold[=<num>] When -qsmp=auto is in effect, controls the amount of automatic loop parallelization that occurs. The value of <num> represents the lower limit allowed for parallelization of a loop, based on the level of "work" present in a loop. Default: <num> must be a positive integer of 0 or greater. If you specify threshold with no suboption, the program uses a default value of 100.

Specifying -qsmp without suboptions is equivalent to -qsmp=auto:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100 or -qsmp=opt:explicit:noomp:norec_locks:nonested_par:schedule=runtime:nostackcheck:threshold=100.

Default: -qnosmp

-qspeculateabsolutes | -qnospeculateabsolutes Works with the -qtocmerge -bl:file for non-IPA links and with the -bl:file for IPA links to disable speculation at absolute addresses. The bl:file is necessary for the compiler to know which addresses are absolutes.

Default: -qspeculateabsolutes

-qstrict | -qnostrict Turns off aggressive optimizations which have the potential to alter the semantics of your program. -qstrict sets -qfloat=nofltint:norsqrt. -qnostrict sets -qfloat=rsqrt. This option is only valid with -O2 or higher optimization levels.

Default: o -qnostrict at -O3 or higher. o -qstrict otherwise.

-qstrict_induction | -qnostrict_induction Turns off loop induction variable optimizations that have the potential to alter the semantics of your program.

Default: o -qnostrict_induction at -O2 or higher. o -qstrict_induction otherwise.

-qtocmerge | -qnotocmerge Enables TOC merging to reduce TOC pointer loads and improves the scheduling of external loads. Reads from the file specified in -bImportfile linker option and merges the address information to access ranges of external addresses using a single table of contents entry.

Default: -qnotocmerge

-qtune=<suboption> Specifies the architecture system for which the executable program is optimized. <suboption> must be one of the following:

403 Generates object code optimized for all the PowerPC 403 processors. 604 Generates object code optimized for all the PowerPC 604 processors. auto Generates object code optimized for the hardware platform on which the program is compiled. balanced Optimizations are tuned across a selected range of recent hardware. ppc970 Generates instructions specific to PowerPC 970 hardware platforms. pwr3 Generates object code optimized for the POWER3 hardware platforms. pwr4 Generates object code optimized for the POWER4 hardware platforms. pwr5 Generates object code optimized for the POWER5 hardware platforms. pwr6 Generates object code optimized for the POWER6 hardware platforms. rs64a Generates object code optimized for the RS64I processor. rs64b Generates object code optimized for the RS64II processor. rs64c Generates object code optimized for the RS64III processor.

Default: -qtune=balanced when the default -qarch setting is in effect. Otherwise, the default depends on the effective -qarch setting.

-qunroll[=<suboption>] | -qnounroll Unrolls inner loops in the program. This can help improve program performance. The suboptions are:

auto Instructs the compiler to perform basic loop unrolling. yes Instructs the compiler to search for more opportunities for loop unrolling than that performed with auto. In general, this suboption is more likely to increase compile time or program size than auto processing, but it may also improve your application's performance. no Instructs the compiler to not unroll loops.

Default: -qunroll=auto

If -qunroll is specified with no suboptions, the compiler assumes -qunroll=yes. -qnounroll is equivalent to -qunroll=no.

-qunwind | -qnounwind Informs the compiler that the stack can be unwound while a routine in the compilation is active. Specifying -qnounwind can improve the optimization of non-volatile register saves and restores.

Default: -qunwind

Linking options -b{dynamic|shared|static} Controls how shared objects are processed by the linkage editor. The suboptions are:

dynamic, shared Causes the linker to process subsequent shared objects in dynamic mode. In dynamic mode, shared objects are not statically included in the output file. Instead, the shared objects are listed in the loader section of the output file. -bdynamic and -bshared are synonymous. static Causes the linker to process subsequent shared objects in static mode. In static mode, shared objects are statically linked in the output file.

Default: -bshared

-bmaxdata:<bytes> Specifies the maximum amount of space to reserve for the program data segment for programs where the size of these regions is a constraint. Combined data space is slightly less than 256MB, or lower, depending on the limits for the user ID.

Default: -bmaxdata:0

-brtl Controls runtime linking for the output file.

-qcrt | -qnocrt Instructs the linker to use the standard system startup files at link time.

Default: -qcrt

-e <name> Sets the entry name for a shared executable and is only used together with -qmkshrobj.

-f<file_name> Names a file to store a list of object files for the compiler to pass to the linker. The <file_name> file should contain only the names of object files. There should be one object file per line.

-L<dir> Searches the path directory for library files specified by the -l<key> option.

Default: The default is to search only the standard directories.

-l<key> Searches the file lib<key>.so and then lib<key>.a for dynamic linking, or only lib<key>.a for static linking.

Default: The default is to search only some of the compiler runtime libraries.

-qlib | -qnolib Specifies whether the compiler should use the standard system libraries at link time. -qnolib is similar to the gcc option nostdlib; the driver will not pass the standard system startup files or libraries when linking.

Default: -qlib

-qtwolink | -qnotwolink (C++) Links twice in order to minimize the number of static constructors included from libraries and object files.

Default: -qnotwolink

-Z<prefix> This linker option specifies a prefix for the library search path. This is useful when developing a new version of a library.

Portability and migration options -qalign=<suboption> Specifies what aggregate alignment rules the compiler uses for file compilation, where the alignment suboptions are:

bit_packed The compiler uses the bit_packed alignment rules. full The compiler uses the RISC System/6000 alignment rules. This is the same as power. mac68k The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the twobyte suboption. natural The compiler maps structure members to their natural boundaries. packed The compiler uses the packed alignment rules. power The compiler uses the RISC System/6000 alignment rules. twobyte The compiler uses the Macintosh alignment rules. This suboption is valid only for 32-bit compilations. It is the same as the mac68k suboption.

Default: -qalign=full

-qalignrulefor=power=[no]typedefrespectsrule (C++) When used with -qalign=power, determines whether a 4-byte alignment ceiling is applied to non-first members of structures that are of type typedef to array of element type that exceeds the alignment ceiling.

typedefrespectsrule | notypedefrespectsrule When typedefrespectsrule is in effect, the member follows the normal alignment rules for -qalign=power. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V6.0 and earlier. When notypedefrespectsrule is in effect, a member that exceeds the alignment ceiling of 4 bytes is aligned on 4-byte boundaries. This suboption provides compatibility with code compiled with -qalign=power with XL C++ V7.0 and V8.0.

Default: -qalignrulefor=power=typedefrespectsrule

-qgenproto[=parmnames] | -qnogenproto (C) Generates ANSI prototypes from K&R function definitions and displays them on standard output. Specifying -qgenproto without '=parmnames' will cause prototypes to be generated without parameter names.

Default: -qnogenproto

-qnamemangling=<scheme> (C++) Chooses the name mangling scheme for external symbol names generated from C++ source code. The <scheme> can be:

ansi Fully supports the most recent language features of Standard C++. v9 Compatible with XL C++ V9.0. v8 Compatible with XL C++ V8.0. v7 Compatible with XL C++ V7.0. v6 Compatible with VisualAge C++ V6.0. v5 The scheme for VisualAge C++ V5.0. v4 The scheme for VisualAge C++ V4.0. v3 The scheme for VisualAge C++ releases before V4.0. compat Same as v3.

Default: -qnamemangling=ansi

-qobjmodel={classic|ibm} (C++) Specifies the object model.

classic This object model is compatible with version 3.6 of the IBM C and C++ compilers. ibm Uses the object model introduced with version 5.0 of VisualAge C++ for AIX. Objects compiled with this object model will use less memory and have better performance for deep inheritance with virtual bases.

Default: -qobjmodel=classic

-qoldpassbyvalue | -qnooldpassbyvalue (C++) Specifies how classes containing const or reference members are passed in function arguments. All classes in the compilation unit are affected by this option. When -qoldpassbyvalue is specified, the compiler mimics the IBM C/C++ compilers v3.6 compiler in that when a class containing a const or reference member is passed as a function argument, it is not passed by value. All such classes in the compilation unit are affected.

Default: -qnooldpassbyvalue

-qupconv | -qnoupconv (C) Preserves the unsigned specification when performing integral promotions.

Default: o -qupconv when -qlanglvl={extended|classic}. o -qnoupconv otherwise.

-qvecnvol | -qnovecnvol Specifies whether to use volatile or non-volatile vector registers. Volatile vector registers are registers whose value is not preserved across function calls or in the context of save, jump or switch system library functions. If -qnoenablevmx is enabled, this option is ignored.

Default: -qnovecnvol

Compiler customization options -qasm_as=<asm_path> [<flags_list>] Specifies the path and flags used to invoke the assembler in order to handle assembler code in an asm statement. <asm_path> is the full path to the assembler to be used, and <flags_list> is a series of one or more flags (and their arguments), separated by spaces. Single quotes (or double quotes) are required around the string of arguments if any spaces exist.

-B[<prefix>] Determines substitute path names for programs used during compilation, such as the compiler, assembler, linkage editor, and preprocessor, where <prefix> can be any program name recognized by the -t compiler option. The optional <prefix> defines part of a path name to the new programs. The -t parameter, <program>, specifies the program to which the <prefix> is to be appended. When specifying <prefix>, there must be a slash (/) after the folder name.

-qc_stdinc=<paths_list> (C) Changes the standard search location for the XL C headers. <paths_list> is a colon-separated list of paths to search.

-qcpp_stdinc=<paths_list> (C++) Specifies the standard search directories for the XL C++ headers, where <paths_list> is a colon- separated list of paths.

-F[<config_file>][:<stanza>] Names an alternative configuration file (.cfg) for the compiler. <config_file> is the name of a compiler configuration file. <stanza> is the name of the command used to invoke the compiler. This directs the compiler to use the entries under <stanza> in the <config_file> to set up the compiler environment. At least one of the arguments must be supplied.

-qpath=<program>:<path> Constructs alternate program names for compiler components. The program and directory path specified are used in place of the regular program. <program> can be one of the following:
