--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:fbf5f5bd00de543868e05ca20a8db6c2bc1c21db commit r13-9323-gfbf5f5bd00de543868e05ca20a8db6c2bc1c21db Author: Richard Biener <rguent...@suse.de> Date: Mon Oct 28 09:52:08 2024 +0100 tree-optimization/117307 - STMT_VINFO_SLP_VECT_ONLY mis-computation STMT_VINFO_SLP_VECT_ONLY isn't properly computed as union of all group members and when the group is later split due to duplicates not all sub-groups inherit the flag. PR tree-optimization/117307 * tree-vect-data-refs.cc (vect_analyze_data_ref_accesses): Properly compute STMT_VINFO_SLP_VECT_ONLY. Set it on all parts of a split group. * gcc.dg/vect/pr117307.c: New testcase. (cherry picked from commit 19722308a286d9a00eead8ac82b948da8c4ca38b)
