Honza,
Your patch seems to make --param max-inline-insns-auto= ineffective:
gfc -Ofast -funroll-loops -ftree-loop-linear -fomit-frame-pointer --param max-inline-insns-auto=4000 -fwhole-program -fstack-arrays ac.f90
8.105u 0.005s 0:08.11 99.8% 0+0k 0+5io 0pf+0w
while the timing was ~2.7s with a 125 threshold before the patch.
Cheers,
Dominique
