The threshold for > fatigue.f90 was322 before revision 169136 and is now 1520 (~x5). Interesting. Do you know what function we fail to inline? Can you attach ipa-inline dump from both settings? I know that also c-ray wants to increase inline limits. I can increase them a bit, but not by factor of 5, since that would cause code size explosion at -O3. (I did some tests on this two weeks ago) Honza
