--- Comment #11 from Jeffrey A. Law <law at gcc dot gnu.org> --- Author: law Date: Fri May 9 04:54:00 2014 New Revision: 210254 URL: http://gcc.gnu.org/viewcvs?rev=210254&root=gcc&view=rev Log: 2014-05-08 Jeff Law <l...@redhat.com> PR tree-optimization/61009 * tree-ssa-threadedge.c (thread_through_normal_block): Return a tri-state rather than a boolean. When a block is too big to thread through, inform caller via negative return value. (thread_across_edge): If a block was too big for normal threading, then it's too big for a joiner too, so remove temporary equivalences and return immediately. PR tree-optimization/61009 * g++.dg/tree-ssa/pr61009.C: New test. Added: trunk/gcc/testsuite/g++.dg/tree-ssa/pr61009.C Modified: trunk/gcc/ChangeLog trunk/gcc/testsuite/ChangeLog trunk/gcc/tree-ssa-threadedge.c
