--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note that "callgraph functions expansion" is all of the GIMPLE passes.  With
GCC 14.1.0 and release checking -O0 takes 10s with most time spent in RA
and IPA while with -O2 it takes 21s with a very flat profile, so IMO nothing
to see there?
