Yeah, pretty much any large (>1kb) buffer copy algorithm runs fastest through SSE2 ever since 128-bit came out.  The raw power overcomes the need for tweaking the loop instead of just using rep movsd.

I think the asm guys have the best code we could hope for already written up on a few pages.  Agner Fog, Paul Hsieh et al.  If we could leech their strategy (if meaning legal) then I can see a good use for such a thing.  I guess we just ought to wait for AST reflection.
