The previous MMX bitslicer (the one which was used during the DES-II
contest) was a mixture of C and assembly. Bruce Ford modified it and
rewrote it in assembly language.
The RC5 MMX core is already entierely in assembly language. This
doesn't mean it's optimal for all processors, I think it was
specifically targeted for Pentium processors. Later we will try to
optimize it for K6-2 processors and perhaps others as well.
