------- Comment #3 from pinskia at gcc dot gnu dot org 2006-06-04 20:03 -------
This was a P2 before P3 became default.
It would also be nice if we can get numbers for 4.1.1.

------- Comment #4 from rguenth at gcc dot gnu dot org 2006-07-10 12:32 -------
Numbers for -static -O3 -march=pentium4 -fomit-frame-pointer (on a P4)
3.4.6: 8.1s
4.0.3: 7.3s
4.1.1: 13.5s
4.2.0: 4.2s
(is there a correctness check inside the benchmark?)
with FDO:
3.4.6: 5.8s
4.0.3: 9.8s
4.1.1: 10.5s
4.2.0: 4.2s
indeed interesting that we loose on FDO for 4.0, and bad
that we're that much slower for 4.1. Good for mainline though.
