(handle_lhs_call): Process return constraints. Add escape constraints if necessary. (handle_const_call): Fill out return constraints. Make nested case more precise. Avoid consttmp if possible. (handle_pure_call): Fill out return constraints. Avoid callused if possible. (find_func_aliases): Simplify call handling. * gcc.c-torture/execute/pr39120.c: New testcase. 2009-03-27 Richard Guenther <rguent...@suse.de> PR tree-optimization/39120 * tree-ssa-structalias.c (do_sd_constraint): Do not use CALLUSED as a representative. (solve_graph): Do propagate CALLUSED. (handle_pure_call): Use a scalar constraint from CALLUSED for the return value. (find_what_p_points_to): CALLUSED shall not appear in poins-to solutions. * gcc.dg/torture/pta-callused-1.c: New testcase.
