That block of text was written by me. Jim's mail client and mine
sometimes disagree about line wrapping so the quoting ended up a little
broken. By the way I'm *now* quoting from the mail archive, I never got
the mail I'm quoting here - or perhaps I accidentally deleted it somehow.

OT, what I meant is that it's very easy to add mdfourmmx() to a format
that already supports intrinsics.

No, I don't mind keeping them although I have no use of them myself.
Since they use the same buffer layout as the intrinsics, there is
practically no extra work. I already have a working patch that adds
Simons's MD4 .S as posted here (but modified a little):
