miscompiled tree-ssa-structalias.ii on AIX
It looks like tree-ssa-structalias.c is being miscompiled, particularly
build_pred_graph. If I add __attribute__((optimize("-O0"))) to
build_pred_cgraph's definition and rebuild stage2's cc1 we have a
non-segfaulting cc1.
I wonder if we can now build a cross (with attachment 40673) to
--target=powerpc-ibm-aix7.2.0.0 and use the attached tree-ssa-structalias.ii to
compare before and after dumps.
