--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
On trunk we're back to performance before that specific regression (but
performance goes up and down a lot).  For released GCCs:

https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=1028.10.0&plot.1=1145.10.0&plot.2=469.10.0&

(the zen4 numbers have to little variance to show me a graph)

So I declare it fixed.
