I think it is better to set sse on a USE flag so if a program is made
to use them (i.e. X.org), it can, but it doesn't affect the other

And, directly from the X.org ebuild,
I was looking over the internet for some CFLAGS for athlon XP and I
didn't found any. Does someone knows what are the best C and CXXFLASG
for athlon XP ?

You'll want the usual -O2 -pipe -fomit-frame-pointer, but also use
I know the safe ones:
-march=athlon-xp -O3 -fomit-frame-pointer -pipe
You can use -02 if you don't want to take much time in compiling and
in some cases the binary is actually faster than -O3 (I heard this
from others, I'm testing it now).
Also -pipe is only supposed to make compile time

Fine, but no need to add mmx, 3dnow!, sse or sse2, as these are
implied by
You're welcome. By the way, look for something about using sse
instruction for math. It speeds things up a bit. And put mmx and sse
in you USE variable

Yes, as long as it's the Socket A version. Not sure about the socket
754 version, which may (or may not) use amd64.

Oh, Raphael, concerning what you said: By the way, look for something

speaking of -mfpmath=sse.

I believe the way mtune and march is like this:
Think of mtune as 'optional' tuning and march as 'required' tuning,
meaning: compile for athlon-xp with the mtune option, it will run
better on an athlon xp but will also run in i386 (just slower),
whereas march will compile for athlon-xp and will

You might want to specify -mfpmath=sse,387 instead. SSE is capable of
