--- 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.
