re PR tree-optimization/54498 (incorrect code generation from g++ -O)
2012-09-06 Richard Guenther <rguenther@suse.de>
PR tree-optimization/54498
* tree-ssa-alias.h (get_continuation_for_phi): Add flag to
abort when reaching an already visited region.
* tree-ssa-alias.c (maybe_skip_until): Likewise. And do it.
(get_continuation_for_phi_1): Likewise.
(walk_non_aliased_vuses): When we translated the reference,
abort when we re-visit a region.
* tree-ssa-pre.c (translate_vuse_through_block): Adjust.
