SubjectMMX for kernel
Date

I don't think mmx does really speed up anything real :) well,
gfx maybe, but its much better getting a real cpu (powerpc..)
than getting mmx.

But stop.. 16 bit checksums.. hmm.. well, that may be an option..
anyboidy interested in trying that?

It may even be possible to give gcc these new insns, but I doubt
that it will optimize loops into the required forms.

If you want to profit from MMX, you currently have to write assembler.

for a pentium-optimizing gcc, look at http://www.goof.com/pcg
