Please elaborate. I admit the info I got was from 2004, but it was
from AMD.
What is the situation with processor-specific compilation options?
I'm simply trying to find out if it's worth re-compiling with mmx
support on a 64-bit amd64 system. It seemed wrong to me that Gentoo
would not permit this, which is why I asked the question in the first
place.
I'd greatly appreciate any info.
