GCC 4.0.0 Performance Regressions?

[Jason Bucata]

Is anybody collecting information on performance regressions in 4.0.0 (vs.
3.4.3)?  I've got some results on POVRAY and BYTEmark, and BYTEmark saw some
performance regression, particularly with profiled optimization
(-fprofile-{generate,use}):

I looked at the Bugzilla bug posting guidelines, but I don't know how to
boil this down to a tight testcase that fits those guidelines... and most of
what I saw in Bugzilla pertained to actual breakage anyway.

I'm willing to help out with this if I can get some pointers on what would
be useful to you--and if I can get the time away from my Real Work(TM) to
fiddle with this...
