--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
I see we're running pass_fold_mem_offsets on x86 which takes most of the time
but should be useless on that target? (and it misses a timevar)
Using -fno-fold-mem-offsets gets us to
TOTAL : 92.59 11.83 104.46
1027M
92.59user 11.86system 1:44.49elapsed 99%CPU (0avgtext+0avgdata

GCC 14.2 is
TOTAL : 95.59 15.26 110.88
1028M
95.59user 15.30system 1:50.93elapsed 99%CPU (0avgtext+0avgdata

so the culprit is identified.
