--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Fri Dec 9 09:21:36 2016 New Revision: 243476 URL: https://gcc.gnu.org/viewcvs?rev=243476&root=gcc&view=rev Log: PR tree-optimization/78726 * tree-ssa-reassoc.c (make_new_ssa_for_def): Add OPCODE and OP argument. For lhs uses in debug stmts, don't replace lhs with new_lhs, but with a debug temp set to new_lhs opcode op. (make_new_ssa_for_all_defs): Add OPCODE argument, pass OPCODE and OP down to make_new_ssa_for_def. (zero_one_operation): Call make_new_ssa_for_all_defs even when stmts_to_fix is empty, if *def has not changed yet. Pass OPCODE to make_new_ssa_for_all_defs. * gcc.c-torture/execute/pr78726.c: New test. * gcc.dg/guality/pr78726.c: New test.
