--- Comment #152 from Filip Kastl <pheeck at gcc dot gnu.org> ---
I've just noticed that this bug got worse. Running
time gcc -O2 all.i
for GCC 14.2 gets me
real 2m57.090s
user 2m36.641s
sys 0m20.309s
but running the same thing with trunk GCC gets me
real 25m36.666s
user 25m14.545s
sys 0m21.044s
gcc -v for my GCC 14.2:
