[Bug middle-end/42339] New: [graphite] Autopar on SPEC 2006 fails

[grosser at gcc dot gnu dot org]

gcc.gnu.org/svn/gcc/trunk@154983

Linux 2.6.22.17-0.1-default #1 SMP x86_64 x86_64 x86_64 GNU/Linux

../../git_trunk/configure --disable-bootstrap --enable-languages=c,c++,fortran
--with-cloog=/home/grosser/gcc/tools/bin/cloog-ppl-old
--with-ppl=/home/grosser/gcc/tools/bin/ppl --with-gmp=/usr/local
--with-mpfr=/home/grosser/gcc/tools/bin/mpfr
--prefix=/home/grosser/gcc/gcc/install/trunk-old 

base flags:
-O2 -fno-loop-block -fno-loop-strip-mine

peak flags:
-O2 -fno-loop-block -fno-loop-strip-mine -ftree-parallelize-loops=4
-floop-parallelize-all 


What I get:
1. perlbench and cactusADM have a runtime error with autopar enabled
2. gcc goes in an invinite loop.

All the other benchmarks work, but do not have any performance differences.
