What's the engineering reason for the ASM code as opposed to just
sticking with the C code?  It seems that for the vast majority of users,
there's no difference in performance between the C code and the
ASM-tuned code.  My guess (prejudice?) is that this would really only
make a big difference for high volume operations.
