--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Guenther <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:37e27de43133b87ceb529d863f0d1f54d87cf2d8 commit r10-5982-g37e27de43133b87ceb529d863f0d1f54d87cf2d8 Author: Richard Biener <rguent...@suse.de> Date: Wed Jan 15 13:29:25 2020 +0100 middle-end/93273 - fix sinking clobbers across backedges The previous work to fix PR93199 didn't take into account backedges when defering insertion. The following simply avoids to defer in that case since we know we'll not take secondary opportunities there. 2020-01-15 Richard Biener <rguent...@suse.de> PR middle-end/93273 * tree-eh.c (sink_clobbers): If we already visited the destination block do not defer insertion. (pass_lower_eh_dispatch::execute): Maintain BB_VISITED for the purpose of defered insertion. * g++.dg/torture/pr93273.C: New testcase.
