GCC mainline gets an ICE compiling crafty from SPEC CPU2000 on
powerpc64-linux:
elm3b149% /home/janis/tools/gcc-mline-20050421/bin/gcc -m64 -O2 -ftree-vectorize
-maltivec -c crafty_bug.c
crafty_bug.c: In function ?main?:
crafty_bug.c:31: internal compiler error: tree check: expected ssa_name, have
var_decl in ssa_mark_def_sites, at tree-into-ssa.c:3055
The test case, extracted from crafty's main.c, is still pretty big,
but taking out anything else made it work. I tried it on another
system where it got a segfault instead, and some small changes caused
segfaults with the compiler which I was reducing it.
I first see the ICE with this patch from law but it might merely be
a latent bug, particularly since the test case is so touchy:
