re PR middle-end/71062 (r235622 and restrict pointers)
2016-05-12 Richard Biener <rguenther@suse.de>
PR tree-optimization/71062
* tree-ssa-alias.h (struct pt_solution): Add vars_contains_restrict
field.
* tree-ssa-structalias.c (set_uids_in_ptset): Set vars_contains_restrict
if the var is a restrict tag.
* tree-ssa-alias.c (ptrs_compare_unequal): If vars_contains_restrict
do not disambiguate pointers against it.
(dump_points_to_solution): Re-structure and adjust for new
vars_contains_restrict flag.
* gimple-pretty-print.c (pp_points_to_solution): Likewise.
* gcc.dg/torture/pr71062.c: New testcase.
