--- Comment #11 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:938a02a589dc22cef65bba2b131fc9e4874baddb commit r13-128-g938a02a589dc22cef65bba2b131fc9e4874baddb Author: Richard Biener <rguent...@suse.de> Date: Mon Feb 21 11:05:58 2022 +0100 tree-optimization/104595 - vectorization of COND_EXPR with bool load The following fixes an omission in bool pattern detection that makes it fail when check_bool_pattern fails for COND_EXPR. That's not what it should do, instead it should still pattern recog to var != 0 even if no further adjustments to the def chain are necessary when var is not a mask already. 2022-02-21 Richard Biener <rguent...@suse.de> PR tree-optimization/104595 * tree-vect-patterns.cc (vect_recog_bool_pattern): For COND_EXPR do not fail if check_bool_pattern returns false. * gcc.dg/vect/pr104595.c: New testcase.
