--- Comment #3 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:6ce7008cfa1a240895ecca0898e7dbaecd975567 commit r14-8280-g6ce7008cfa1a240895ecca0898e7dbaecd975567 Author: Richard Biener <rguent...@suse.de> Date: Fri Jan 19 09:23:48 2024 +0100 tree-optimization/113494 - Fix two observed regressions with r14-8206 The following handles the situation where we lack a loop-closed PHI for a virtual operand because a loop exit goes to a code region not having any virtual use (an endless loop). It also handles the situation of edge redirection re-allocating a PHI node in the destination block so we have to re-lookup that before populating the new PHI argument. PR tree-optimization/113494 * tree-vect-loop-manip.cc (slpeel_tree_duplicate_loop_to_edge_cfg): Handle endless loop on exit. Handle re-allocated PHI.
