--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:87da0caaec663bd427147c04e5784d7843ede96a commit r8-10806-g87da0caaec663bd427147c04e5784d7843ede96a Author: Richard Biener <rguent...@suse.de> Date: Thu Oct 1 09:29:32 2020 +0200 tree-optimization/97255 - missing vector bool pattern of SRAed bool SRA tends to use VIEW_CONVERT_EXPR when replacing bool fields with unsigned char fields. Those are not handled in vector bool pattern detection causing vector true values to leak. The following fixes this by turning those into b ? 1 : 0 as well. 2020-10-01 Richard Biener <rguent...@suse.de> PR tree-optimization/97255 * tree-vect-patterns.c (vect_recog_bool_pattern): Also handle VIEW_CONVERT_EXPR. * g++.dg/vect/pr97255.cc: New testcase.
