Hi folks,
Attached is my Altivec l1 matmul kernel. I think I did the scases file
correctly. This is really only a preliminary version, but it may turn
out that I can't do any better than this! Using this kernel, I get 1620
Mflops peak SGEMM on my 533 G4 vs. 670 Mflops for the scalar SGEMM.
These results are for Mac OS X (I have linux but don't have the
Altivec-enabled compiler so I didn't try it there).
