--- Comment #13 from Martin Jambor <jamborm at gcc dot gnu.org> ---
there is still a 5% regression against gcc-10 on zen2 at (just) -Ofast:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=405.50.0&plot.1=414.50.0&plot.2=754.50.0&plot.3=300.50.0&;
4% at -Ofast -march=native:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=406.50.0&plot.1=421.50.0&plot.2=758.50.0&plot.3=301.50.0&;
13% on an Intel IceLake machine at -Ofast -march=native:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=805.50.0&plot.1=845.50.0&plot.2=820.50.0&plot.3=798.50.0&;
5.8% on zen3 at just -Ofast (targetting generic x86_64 ISA):
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=524.50.0&plot.1=504.50.0&plot.2=741.50.0&plot.3=466.50.0&;
