--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Kyrylo Tkachov <ktkac...@gcc.gnu.org>: https://gcc.gnu.org/g:7f0ce82a4c033b78ec5131a27bac87271bb95185 commit r11-4382-g7f0ce82a4c033b78ec5131a27bac87271bb95185 Author: Kyrylo Tkachov <kyrylo.tkac...@arm.com> Date: Mon Oct 26 11:42:18 2020 +0000 PR tree-optimization/97546 Bail out of find_bswap_or_nop on non-INTEGER_CST sizes This patch fixes the ICE in the PR by bailing out of find_bswap_or_nop on poly_int sizes. I don't think it intends to handle them and from my reading of the code it's the most appropriate place to reject them here rather than in the callers. Bootstrapped and tested on aarch64-none-linux-gnu. gcc/ PR tree-optimization/97546 * gimple-ssa-store-merging.c (find_bswap_or_nop): Return NULL if type is not INTEGER_CST. gcc/testsuite/ PR tree-optimization/97546 * gcc.target/aarch64/sve/acle/general/pr97546.c: New test.
