re PR tree-optimization/36327 (SCCVN should look through struct copies)
2009-05-25 Richard Guenther <rguenther@suse.de>
PR tree-optimization/36327
* tree-ssa-alias.c (walk_non_aliased_vuses): Add second walker
callback for reference translation or lookup at the point
of may-defs.
* tree-ssa-alias.h (walk_non_aliased_vuses): Adjust prototype.
* tree-ssa-sccvn.c (get_ref_from_reference_ops): Bail out
for union COMPONENT_REFs.
(vn_reference_lookup_3): New callback. Lookup from memset
and CONSTRUCTOR assignment, translate through struct copies.
(vn_reference_lookup_pieces): Make sure to not free the
passed operands array. Adjust walk_non_aliased_vuses call.
(vn_reference_lookup): Adjust walk_non_aliased_vuses call,
make sure we do not leak memory.
