tree-ssa-alias.c (finalize_ref_all_pointers): Remove.
2008-04-29 Richard Guenther <rguenther@suse.de>
* tree-ssa-alias.c (finalize_ref_all_pointers): Remove.
(compute_may_aliases): Do not call finalize_ref_all_pointers.
(compute_flow_insensitive_aliasing): Do not treat
PTR_IS_REF_ALL pointers special.
(get_smt_for): Likewise.
(may_alias_p): Re-structure.
(is_escape_site): A ref-all pointer conversion is not an escape site.
* tree-ssa-structalias.c (find_what_p_points_to): Do not treat
PTR_IS_REF_ALL pointers special.
* tree-ssa-structalias.h (struct alias_info): Remove
ref_all_symbol_mem_tag field.
(PTR_IS_REF_ALL): Remove.
