--- Comment #15 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Fri May 20 08:51:06 2016 New Revision: 236497 URL: https://gcc.gnu.org/viewcvs?rev=236497&root=gcc&view=rev Log: 2016-05-20 Richard Biener <rguent...@suse.de> Backport from mainline 2016-02-01 Bin Cheng <bin.ch...@arm.com> PR tree-optimization/67921 * fold-const.c (split_tree): New parameters. Convert pointer type variable part to proper type before negating. (fold_binary_loc): Pass new arguments to split_tree. * c-c++-common/ubsan/pr67921.c: New test. 2016-05-06 Richard Biener <rguent...@suse.de> PR middle-end/70941 * fold-const.c (split_tree): Always convert to the original type before negating. * gcc.dg/torture/pr70941.c: New testcase. 2016-05-06 Jakub Jelinek <ja...@redhat.com> PR middle-end/70941 * gcc.dg/torture/pr70941.c (abort): Remove prototype. (a, b, c, d): Change type from char to signed char. (main): Compare against (signed char) -1634678893 instead of hardcoded -109. Use __builtin_abort instead of abort. 2016-05-06 Richard Biener <rguent...@suse.de> PR middle-end/70931 * dwarf2out.c (native_encode_initializer): Skip zero-sized fields. * gfortran.dg/pr70931.f90: New testcase. 2016-04-14 Richard Biener <rguent...@suse.de> PR tree-optimization/70623 * tree-ssa-pre.c (changed_blocks): Make global ... (compute_antic): ... local here. Move and fix worklist handling here. Do not clear EDGE_DFS_BACK. (compute_antic_aux): Add dumping for MAX assumed succs. Remove worklist handling, dump when ANTIC_IN changed. (compute_partial_antic_aux): Remove worklist handling. (init_pre): Do not compute post dominators. Add a comment about the CFG order chosen. (fini_pre): Do not free post dominators. * gcc.dg/torture/pr70623.c: New testcase. * gcc.dg/torture/pr70623-2.c: Likewise. 2016-04-25 Richard Biener <rguent...@suse.de> PR tree-optimization/70780 * tree-ssa-pre.c (compute_antic_aux): Also return true if the block wasn't visited yet. (compute_antic): Mark blocks with abnormal preds as visited as they have a final empty antic-in solution already. * gcc.dg/torture/pr70780.c: New testcase.
