[x264-devel] Re: [patch] SSE2 pixel routines - new patch!

[Alexander Izvorski]

Hello,

I tried to post a new SSE2 patch to the list but I think the message
is not getting through (possibly the attachment is too large?).  The
patch is here:

http://www.geocities.com/x264hack/sse2-pixel-routines-v4.diff.txt

and the message I had sent originally is below.  Sorry if it ends up
posting twice.

Regards,
-Alex Izvorski
