--- Comment #1 from Filip Kastl <pheeck at gcc dot gnu.org> ---
This is actually not a regression against GCC 15.
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=1294.477.0&plot.1=1359.477.0&plot.2=1288.477.0&;
Our graphs for Zen5 sadly don't go that far back but I'm guessing that the
introduction of the rrvl pass in r16-271-gd1cada7481420a got us the speedup
which we now lost.
