--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:9f35d8cd767155e9c24f5ef0944168711d38bc6b commit r14-5518-g9f35d8cd767155e9c24f5ef0944168711d38bc6b Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Nov 16 08:32:24 2023 +0100 slp: Fix handling of IFN_CLZ/CTZ [PR112536] We ICE on the following testcase now that IFN_C[LT]Z calls can have one or two arguments (where 2 mean it is well defined at zero). The following patch makes us create child node only for the first argument and compatible_calls_p ensures the other argument is the same, which at least according to the testcase seems sufficient because of vect patterns. 2023-11-16 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/112536 * tree-vect-slp.cc (arg0_map): New variable. (vect_get_operand_map): For IFN_CLZ or IFN_CTZ, return arg0_map. * gcc.dg/pr112536.c: New test.
