--- Comment #7 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:af4ccaa7515b8e72449448c509916575831e6292 commit r12-284-gaf4ccaa7515b8e72449448c509916575831e6292 Author: Richard Biener <rguent...@suse.de> Date: Thu Apr 29 11:52:08 2021 +0200 tree-optimization/100253 - fix bogus aligned vectorized loads/stores At some point DR_MISALIGNMENT was supposed to be -1 when the access was not element aligned. That's obviously not true at this point so this adjusts both store and load vectorizing to no longer assume this which in turn allows simplifying the code. 2021-04-29 Richard Biener <rguent...@suse.de> PR tree-optimization/100253 * tree-vect-stmts.c (vectorizable_load): Do not assume element alignment when DR_MISALIGNMENT is -1. (vectorizable_store): Likewise. * g++.dg/pr100253.C: New testcase.
