[x264-devel] [PATCH] AltiVec implementation of hadamard_ac routines

[Takashi Mochizuki]

Guillaume-san,
I have made a test binary of my QuickTime Component x264Encoder, using  
r1096 with your hadamard_ac altivec patch.

To build with your patch, gcc does warn some printf with %vhd. I have  
cut them all.
Tried with 15sec VGA sample, and it runs well. No binary diff found in  
each video stream.

On my G4 1.67GHz(MacOS X 10.5.6), it shows pretty positive performance  
gain. (+1.8% overall)
  r1096 + patch : 165.5 sec
