--- Comment #12 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I can once again confirm the slowdown on a zen1-based machine (commit
6e1e0decc9e vs gcc 7.5) but it is not present on a zen2-based one. I wonder
whether the bug should me marked as WONTFIX.

--- Comment #17 from Martin Jambor <jamborm at gcc dot gnu.org> ---
Looking LNT (and excluding machines which are no longer active), the worst
regression is now 4% and that only at -O2 -Ofast. Probably not a very high
priority then (do we want to close this?).
