CPUTYPE= athlon-xp CFLAGS= -O2 -pipe -fomit-frame-pointer -mmmx -msse -m3dnow -mfpmath=sse COPTFLAGS= -O -pipe
Now what I'm wondering is if those extras like mmmx msse actually do anything. The
only reason they're in there is because I saw them on a website about what people
use to optimize gentoo. I had nothing better to do so I recompiled the world with
them. I didn't really notice anything good or bad happening after that. I did have
to mess around with a couple of makefiles to get around the strict-aliasing problem
that O2 introduces. Besides that, though, are there any advantages or disadvantages
to compiling with those optimizations and switches?
Does -mfpmath=sse actually do anything relevent for the FreeBSD world? I know
what the GCC manual says about it but I'd rather hear some real world info.
An enquiring mind wants to know.
