Subject: RE: MD5 Generic improvements

separately or not?

Yes. 

The md5-gen code is SSE-intrinsic 'ready' and is separate FROM that patch.
However, to get any benefit of the intrinsic functionality, you will have to
have that intrinsic patch applied to the source.  The intrinsic patch will
not touch the md5-gen code. However, once you apply THAT patch, the md5-gen
will operate using the faster intrinsic.

So, if you updated your source to the new md5-gen code, and had not applied
the intrinsic patch, then there is no way to build USING intrinsic.
However, the md5-gen would build properly (all of the intrinsic code would
be #defined 'out' of the build).

Jim.
