tree-ssa-structalias.c (set_uids_in_ptset): Use the pointed-to type for TBAA pruning.
2007-11-15 Richard Guenther <rguenther@suse.de>
* tree-ssa-structalias.c (set_uids_in_ptset): Use the pointed-to
type for TBAA pruning.
(find_what_p_points_to): Call set_uids_in_ptset with the original
pointer, not the decl of the solution we collapsed to.
