--- Comment #4 from CVS 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:323209cd73bf1d81d91637677db5883afc8ae5f6 commit r14-4682-g323209cd73bf1d81d91637677db5883afc8ae5f6 Author: Richard Biener <rguent...@suse.de> Date: Tue Oct 17 13:42:59 2023 +0200 tree-optimization/111846 - put simd-clone-info into SLP tree The following avoids bogously re-using the simd-clone-info we currently hang off stmt_info from two different SLP contexts where a different number of lanes should have chosen a different best simdclone. PR tree-optimization/111846 * tree-vectorizer.h (_slp_tree::simd_clone_info): Add. (SLP_TREE_SIMD_CLONE_INFO): New. * tree-vect-slp.cc (_slp_tree::_slp_tree): Initialize SLP_TREE_SIMD_CLONE_INFO. (_slp_tree::~_slp_tree): Release it. * tree-vect-stmts.cc (vectorizable_simd_clone_call): Use SLP_TREE_SIMD_CLONE_INFO or STMT_VINFO_SIMD_CLONE_INFO dependent on if we're doing SLP. * gcc.dg/vect/pr111846.c: New testcase.
