--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Miscompilation started with r15-6464-gc86e1c54c6f8771d08a8c070717b80607f990f8a Not sure if we can consider it a regression though, as the -favoid-store-forwarding option has only been added in r15-5640-g1d8de1e93ea00f7797f61cf8e05c47ca86f21f8c
