--- Comment #2 from Martin Jambor <jamborm at gcc dot gnu.org> ---
Reconfirmed in 2021 too, also on LNT.  The best way to see current
status is probably to go to
https://lnt.opensuse.org/db_default/v4/SPEC/spec_report/branch?sorting=3Dgc=
c-7%2Cgcc-8%2Cgcc-9%2Cgcc-10%2Cgcc-11%2Cgcc-trunk
and then enter "554.roms" into the "test name filter" edit field.

On Zen3 we now regress by 5.63% compared to GCC 7 at -O2.

On Zen2 we now regress by 8.35% compared to GCC 7 at -O2.

On Zen1 we now regress by 11.15% compared to GCC 7 at -O2.

On s Kabylake "client" CPU we now regress by 9.06% compared to GCC 7 at -O2.

On a Cascadelake "server" CPU we now regresss by 7.84% compared to GCC 7 at
-O2.=
