--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:c2ab46f377313da5336748eb4fdc20020c047445 commit r12-9409-gc2ab46f377313da5336748eb4fdc20020c047445 Author: Richard Biener <rguent...@suse.de> Date: Tue Mar 21 12:49:36 2023 +0100 tree-optimization/109219 - avoid looking at STMT_SLP_TYPE The following avoids looking at STMT_SLP_TYPE apart from the only place needing it - transform and analysis of non-SLP loop stmts. In particular it doesn't have a reliable meaning on SLP representatives which are also passed as stmt_vinfo to vectorizable_* routines. The proper way to check in those is to look for the slp_node argument instead. PR tree-optimization/109219 * tree-vect-loop.cc (vectorizable_reduction): Check slp_node, not STMT_SLP_TYPE. * tree-vect-stmts.cc (vectorizable_condition): Likewise. * tree-vect-slp.cc (vect_slp_analyze_node_operations_1): Remove assertion on STMT_SLP_TYPE. * gcc.dg/torture/pr109219.c: New testcase. (cherry picked from commit 26adc870e3675591050f37edab46850b97a3c122)
