------- Comment #29 from hubicka at gcc dot gnu dot org 2005-10-31 19:15 -------
Actually I have to reopen this. When playing around on pentiumM or opteron, I
still get roughly 20% regression (6s to 8s), 4.1 and 4.0 scores are about the
same on both machines. For some reason this don't reproduce on my Athlon.
This however don't seem to be related to inlining limits as ramping them up so
everything gets inlined still won't make the testcase work better, so someone
would probably have to oprofile it and figure out what is still regressing.
I think it is non-critical tough.
