2008-06-04 Richard Guenther <rguenther@suse.de>
* tree-flow-inline.h (is_global_var): Do not check TREE_STATIC
on MTAGs.
(is_call_clobbered): Always check var_ann->call_clobbered.
(mark_call_clobbered): Always set var_ann->call_clobbered.
(clear_call_clobbered): Always clear var_ann->call_clobbered.
* tree-ssa-alias.c (mark_non_addressable): Use clear_call_clobbered.
(reset_alias_info): Clear call clobbering info on MTAGs and
globals as well.
(set_pt_anything): Set pt_global_mem.
(create_tag_raw): Adjust comment.
(may_be_aliased): Do not check TREE_PUBLIC on MTAGs.
