--- Comment #13 from CVS 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:08f263e703c4100fa7b9f08cb26cee6c0bd75e4a commit r12-7764-g08f263e703c4100fa7b9f08cb26cee6c0bd75e4a Author: Richard Biener <rguent...@suse.de> Date: Tue Mar 22 12:28:30 2022 +0100 tree-optimization/105012 - fix ICE from local DSE of if-conversion The following guards dse_classify_store with the same condition as the DSE pass does - availability of a virtual definition. For the PR we run into the fortran frontend generating a clobber for a FUNCTION_DECL lhs which is ignored by the operand scanner and has no virtual operands assigned. Apart from fixing the frontend the following fixes the ICE by adjusting if-conversion. 2022-03-22 Richard Biener <rguent...@suse.de> PR tree-optimization/105012 * tree-if-conv.cc (ifcvt_local_dce): Only call dse_classify_store when we have a VDEF.
