Version ppl-0.10.2-1 of the Parma Polyhedra Library (PPL) has been released.

PACKAGE DESCRIPTION ===================

Homepage: http://www.cs.unipr.it/ppl/ License : GNU GPL 3 or later

The Parma Polyhedra Library (PPL) provides numerical abstractions specially targeted at applications in the field of analysis and verification of complex systems. These abstractions include convex polyhedra, defined as the intersection of a finite number of (open or closed) halfspaces, each described by a linear inequality (strict or on-strict) with rational coefficients; some special classes of polyhedra shapes that offer interesting complexity/precision tradeoffs; and grids which represent regularly spaced points that satisfy a set of linear congruence relations.

This package is needed to build GCC 4.4 with the Graphite loop optimizations - http://gcc.gnu.org/install/prerequisites.html. The package includes > 4 MB of documentation, which is packaged separately

The cygwin PPL release comprises four packages libppl - the run time libraries ppl-devel - the headers and link libraries ppl - man pages, licenses, etc ppl-doc - 4 MB of documentation

INSTALL OR UPGRADE NOTES ========================

Standard install built with gcc-4.3.2 and g++-4.3.2. For correct functionality, users may need to link applications with LDFLAGS=-Wl,--enable-auto-import. The majority of the PPL tests fail when built without this option.

PPL was built with the C++ and C interfaces. Other interfaces may be provided, if requested, in future Cygwin releases.
