--- Comment #6 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:c7cb0dd94589ab501bca27f93641b4074e5a2e99 commit r15-1670-gc7cb0dd94589ab501bca27f93641b4074e5a2e99 Author: Richard Biener <rguent...@suse.de> Date: Wed Jun 26 19:23:26 2024 +0200 tree-optimization/115652 - amend last fix The previous fix breaks in the degenerate case when the discovered last_stmt is equal to the first stmt in the block since then we undo a required stmt advancement. PR tree-optimization/115652 * tree-vect-slp.cc (vect_schedule_slp_node): Only insert at the start of the block if that strictly dominates the discovered dependent stmt.
