--- Comment #10 from Martin Liška <marxin at gcc dot gnu.org> ---
I can't confirm that on a Ryzen 5 machine, it's actually faster on trunk:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=154.477.0&plot.1=65.477.0&plot.2=82.477.0&plot.3=35.477.0&;

Out of all configurations, the benchmark is actually faster on trunk than on
GCC-8. Thus I'm closing that.
