[x264-devel] [PATCH] SSE2 motion compensation [from before] + MMX/SSE2/SSSE3 frame_lowres_init

[Jason Garrett-Glaser]

Correction to my previous patch.  Line:

+    for( x = 0; width - x >= 2; x++ )\

should be

+    for( ; width - x >= 2; x++ )\

A quick test of the code yields:

SSSE3: 2.23m clocks
SSE2: 3.36m clocks
MMX: 7.46m clocks
Scalar/C: 7.5m clocks

for 1280x720 input on a Core 2 Merom.
