I've been looking for possible flags, optimizations, really anything
that would help me setup my laptop to use mmx and 3dnow. I've updated
/etc/make.conf to -march to the drum of a k6-2, but I'm not even sure
if mmx and 3dnow are being taken into consideration for compiling and
such, especially for Xorg.
I did some googling and found people who used CFLAGS like -mmmx and
-m3dnow, but when I run with those options, they fail and said to be
invalid. they don't appear in 'man gcc' which should have been the
first place i looked. I'm not finding anything in terms of compiling
or configuring Xorg to use 3dnow or mmx, or even how to check to see
if they are automatically detected and used.
