AMD 64 question

Sorry, I was hoping that somebody may know this:

I don't use 64 bit gentoo, but 32 bit mainly for convenience's sake. Emulating 32 bit linux inside of 64 bit linux is kind of backwards to me. I hope they clean it all up soon and make it all one package (it's hella fast though, I just can't get some of my proggys to work - anyway, off topic)...

Anyway, can I use the -march=k8 in my make.conf file in a 32 bit environment and build only 32 bit code? I'd love to optimize my build for the CPU...

Please, need help... Mid install at the moment.

to use the k8 flag you need gcc 3.4 before that it wasnt desighned for amd64s hence all the probs with people using Os but is fine now

So, it's okay to use in a 32 bit environment? It won't build any 64 bit code or nothin'?

no to build 64bit you would need CHOST=x86_64-pc-linux-gnu and probably most of the system including the kernel compiled as 64bit
