--- Comment #11 from Filip Kastl <pheeck at gcc dot gnu.org> --- And btw there is also this slowdown https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=1101.10.0 which is 20%! But I didn't manage to replicate this on another Zen4 machine. So it probably doesn't make sense to try to do anything about it. Anyway, I thought it might be worth to mention.
