--- Comment #3 from Jeffrey A. Law <law at gcc dot gnu.org> --- Author: law Date: Thu Jun 5 18:25:02 2014 New Revision: 211287 URL: http://gcc.gnu.org/viewcvs?rev=211287&root=gcc&view=rev Log: PR tree-optimization/61289 * tree-ssa-threadedge.c (invalidate_equivalences): Remove SRC_MAP and DST_MAP parameters. Invalidate by walking all the SSA_NAME_VALUES looking for those which match LHS. All callers changed. (record_temporary_equivalences_from_phis): Remove SRC_MAP and DST_MAP parameters and code which manipulated them. All callers changed. (record_temporary_equivalences_from_stmts_at_dest): Remove SRC_MAP and DST_MAP parameters. Simplify invalidation code by just calling invalidate_equivalences. All callers changed. (thread_across_edge): Simplify now that we don't need to maintain the map of equivalences to invalidate. PR tree-optimization/61289 * g++.dg/pr61289.C: New test. * g++.dg/pr61289-2.C: New test.
