--- Comment #1 from Filip Kastl <pheeck at gcc dot gnu.org> ---
I looked at this in more detail. Actually, only some of the slowdowns I listed
look like regressions. Here they are (with a comparison to GCC 14):
https://lnt.opensuse.org/db_default/v4/SPEC/graph?&plot.8=1069.70.0&plot.9=577.70.0&;
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.8=1042.70.0&plot.9=580.70.0&;
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.8=1066.70.0&plot.9=578.70.0
Sorry, I was a bit too hasty.
Also, I am not even sure if these graphs show a recent regression. Notice the
orange vertical lines in the graph. Those represent that we updated the system
of the benchmarking machine at that time. They unfortunately coincide with
r15-6661-gc5db3f50bdf34e (the commit r15-7871-gf870302515d5fc is fixing). This
means that the graph is hard to read. There definitely is a regression of
433.milc between GCC 14 and GCC 15. However, I now don't feel confident saying
that it must be between
r15-7846-gda8aaa7784810e
r15-7877-g888e70b3226225
I'll suspend this bug for now and think about this some more.
