--- Comment #13 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:fbcbbfe2bf83eb8b1347144eeca37b06be5a8bb5 commit r15-7331-gfbcbbfe2bf83eb8b1347144eeca37b06be5a8bb5 Author: Richard Biener <rguent...@suse.de> Date: Mon Feb 3 09:55:50 2025 +0100 tree-optimization/118717 - store commoning vs. abnormals When we sink common stores in cselim or the sink pass we have to make sure to not introduce overlapping lifetimes for abnormals used in the ref. The easiest is to avoid sinking stmts which reference abnormals at all which is what the following does. PR tree-optimization/118717 * tree-ssa-phiopt.cc (cond_if_else_store_replacement_1): Do not common stores referencing abnormal SSA names. * tree-ssa-sink.cc (sink_common_stores_to_bb): Likewise. * gcc.dg/torture/pr118717.c: New testcase.
