Test 183.equake from SPEC CPU2000 gets wrong results on powerpc64-linux (-m32
or -m64) when compiled with either "-O2 -fgraphite-identity" or "-O2
-floop-parallelize-all". I'll attach an executable testcase that demonstrates
the failure. Test 178.galgel fails with the same options but I haven't
investigated it.
The failure starts with the merge from the Graphite branch for r150301. With
options "-O2 -fgraphite-identity" the minimized testcase and the two CPU2000
tests pass with r150248, the last revision before that merge that builds on
powerpc64-linux. They also pass with GCC 4.4.2 with "-O2 -fgraphite-identity".
