--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Just for the record, my Ryzen machine periodic tester probably improved due to
the revision:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=158.377.0&plot.1=41.377.0&plot.2=70.377.0&plot.3=31.377.0

As seen, it's now about 5% faster than GCC8 branch.
