--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alex Coplan <acop...@gcc.gnu.org>: https://gcc.gnu.org/g:aca1f9d7cab3dc1a374a7dc0ec6f7a8d02d2869a commit r14-6784-gaca1f9d7cab3dc1a374a7dc0ec6f7a8d02d2869a Author: Alex Coplan <alex.cop...@arm.com> Date: Thu Dec 21 10:52:44 2023 +0000 aarch64: Prevent moving throwing accesses in ldp/stp pass [PR113093] As the PR shows, there was nothing to prevent the ldp/stp pass from trying to move throwing insns, which lead to an RTL verification failure. This patch fixes that. gcc/ChangeLog: PR target/113093 * config/aarch64/aarch64-ldp-fusion.cc (latest_hazard_before): If the insn is throwing, record the previous insn as a hazard to prevent moving it from the end of the BB. gcc/testsuite/ChangeLog: PR target/113093 * gcc.dg/pr113093.c: New test.
