--- Comment #13 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:66c879571ab1fbdb4b119b8b0a1a30ebc7160057 commit r16-2450-g66c879571ab1fbdb4b119b8b0a1a30ebc7160057 Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Tue Jul 22 10:26:54 2025 -0700 aarch64: Fix fma steering when rename fails [PR120119] Regrename can fail in some case and `insn_rr[INSN_UID (insn)].op_info` will be null. The FMA steering code was not expecting the failure to happen. This started to happen after early RA was added but it has been a latent bug before that. Build and tested for aarch64-linux-gnu. PR target/120119 gcc/ChangeLog: * config/aarch64/cortex-a57-fma-steering.cc (func_fma_steering::analyze): Skip if renaming fails. gcc/testsuite/ChangeLog: * g++.dg/torture/pr120119-1.C: New test.
