Hi all,
While we're on the subject of AMD processors...
Has anyone considered adding Pentium 2/3/4/Athlon/Athlon XP support
to the low level string/bytecopy routines? If we just supported SSE (1)
that'd get us (okay, me) a pretty nice performance boost on the P2, P3,
P4 and Athlon XP, all in one hit. These days, the "average" new computer
supports SSE, and since the GCC 3.x/binutils folk are on their way to
supporting this stuff in a Standard way (e.g. '-msse', '-march=athlon'
etc.) maybe it's time to code something up?
Hmmm.
Duraid
(P.S. Apologies if there's already SSE/3dnow bcopy stuff in the kernel -
I couldn't see it!)
