--- Comment #1 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:95aecacc8d9c40100f01433ba214103e756dc984 commit r16-2709-g95aecacc8d9c40100f01433ba214103e756dc984 Author: Richard Biener <rguent...@suse.de> Date: Fri Aug 1 13:06:51 2025 +0200 Avoid representing SLP mask by scalar op The following removes the scalar mask output from vect_check_scalar_mask and deals with the fallout, eliminating uses of it. That's mostly replacing checks on 'mask' by checks on 'mask_node' but also realizing PR121349 and fixing that up a bit in check_load_store_for_partial_vectors. PR tree-optimization/121349 * tree-vect-stmts.cc (check_load_store_for_partial_vectors): Get full SLP mask, reduce to uniform scalar_mask for further processing if possible. (vect_check_scalar_mask): Remove scalar mask output, remove code conditional on slp_mask. (vectorizable_call): Adjust. (check_scan_store): Get and check SLP mask. (vectorizable_store): Eliminate scalar mask variable. (vectorizable_load): Likewise.
