--- Comment #13 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:7890836de20912bd92afaf5abbeaf9d8c5b86542 commit r14-9316-g7890836de20912bd92afaf5abbeaf9d8c5b86542 Author: Richard Biener <rguent...@suse.de> Date: Tue Mar 5 10:55:56 2024 +0100 tree-optimization/114231 - use patterns for BB SLP discovery root stmts The following makes sure to use recognized patterns when vectorizing roots during BB SLP discovery. We need to apply those late since during root discovery we've not yet done pattern recognition. All parts of the vectorizer assume patterns get used, for the testcase we mix this up when doing live lane computation. PR tree-optimization/114231 * tree-vect-slp.cc (vect_analyze_slp): Lookup patterns when processing a BB SLP root. * gcc.dg/vect/pr114231.c: New testcase.
