Ok, so its not elegant, but it is more mature than writing something
from scratch. The assembler is there for obvious performance reasons;
even gstreamer includes some x86/MMX assembler. But I agree that there
should pure C equivalents for any assembler routines. The question is
whether a cleanup or a complete rewrite is in order. In the case of a
rewrite, surely some implementation details of the spec can be be more
quickly understood from its source. Also, for the purposes I outlined,
compatibility with the Heroine Warrior implementation is desirable.
