--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:439cd07b51676996889b1277afd46c1053d24ebc commit r17-3856-g439cd07b51676996889b1277afd46c1053d24ebc Author: Richard Biener <[email protected]> Date: Wed Sep 2 11:41:23 2026 +0200 tree-optimization/127190 - ICE in vectorizable_lane_reducing The following properly fails analyzing a lane-reducing reduction when vect_get_num_copies_for_invariant fails instead of asserting it does not. While analysis later verifies we can create the constant we use the info here for costing, so we have to fail early. PR tree-optimization/127190 * tree-vect-loop.cc (vectorizable_lane_reducing): Fail when vect_get_num_copies_for_invariant does.
