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 ? -- gentoo-user@gentoo.org mailing list

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

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 2005/6/13, Allan Spagnol Comar [EMAIL PROTECTED]: thak you all On 6/13/05, Raphael Melo de Oliveira Bastos Sales [EMAIL PROTECTED] wrote:

Yes, as long as it's the Socket A version. Not sure about the socket 754 version, which may (or may not) use amd64. On 6/13/05, Raphael Melo de Oliveira Bastos Sales [EMAIL PROTECTED] wrote: By the way, Sempron accepts athlon-xp, right? 2005/6/13, Bruno Lustosa [EMAIL PROTECTED]: On

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
