Debian sparc is 32bit userland. The ppl build as found in the archive is unaffected (gcc -m32). I'll look at the backport of this patch to 4.3.

Hi there,

we are going through the list of architectures supported by Debian, looking for problems affecting the Parma Polyhedra Library. We need advice concerning this bug (we have just added it to GCC Bugzilla):

 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37661

Apparently something is wrong with the default -msoft-quad-float. Should we:

1. do nothing, because (say) Debian will always ship binaries compiled with optimizations turned on;
2. compile with -mhard-quad-float on the sparc64 (would make sense only if SPARC implementations that don't have hardware support for the quad-word floating point instructions are not targeted by Debian);
3. apply a (yet to be identified) workaround;
4. disable support for long doubles on sparc64;
5. do something else.

Thanks for any suggestion. All the best,

Roberto
