--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
I can confirm on LNT znver2 machine, but the bisection points to a different
commit:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=324.387.0&plot.1=311.387.0&plot.2=348.387.0&plot.3=280.387.0&plot.4=297.387.0&

while LNT znver1 machine is not affected and the speed is similar to GCC 9:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=145.387.0&plot.1=49.387.0&plot.2=79.387.0&plot.3=259.387.0&plot.4=29.387.0&
