--- Comment #1 from Martin Jambor <jamborm at gcc dot gnu.org> ---
The same revision also regressed SPEC 2017 INTrate benchmark x264_r by
about 10% at -Ofast -march=native with and without LTO on zen3:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=471.377.0
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=475.377.0
and I suspect (unlike the above, I have not actually verified it) also
on zen2:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=295.377.0
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=287.377.0
