--- Comment #9 from Filip Kastl <fkastl at suse dot cz> --- (In reply to Richard Biener from comment #8) > Does this still happen after r14-8413-g578c7b91f418eb? I think it doesn't happen anymore. I can confirm that both on aarch64 and zen3, both the SPEC2006 and SPEC2017, with -Ofast -march=native -mtune=native -flto perlbench compiles correctly now.
