- Subject: Tracking down gcc-4.0 performance regressions
I recently worked with a UCLA student to boil down
a reported openssl performance regression with gcc-4.0
to a small standalone case (see http://gcc.gnu.org/PR19923).
We have a bit more followup to do there, but it seems
to have been a good use of an student's time.
So, I'm looking around for other reports of performance
regressions in gcc-4.0. So far, the only other ones I've
heard of are those reported in http://www.coyotegulch.com/reviews/gcc4/
I'm tempted to have a student try reproducing and boiling down the POV-Ray
performance regession first. Has anyone else already done that?
I'd hate to repeat work.
Thanks,
Dan
