[x264-devel] Re: [PATCH] Altivec optimizations for quant4x4 and quant4x4dc

[Guillaume POIRIER]

Hi all,
Please find in attachment the altivec-optimized version of quant 
4x4(+dc) and quant 8x8. All now pass regression tests, so they are all 
activated
I've also found out that even though my 4x4 DC also pass regression 
tests, it doesn't seem to be called too often.
It's likely to be because I had to restrict its use to the cases where 
maxQdc < (1<<15).
That can hopefully be improved if I manage to understand why I can't use 
  my 4x4dc with maxQdc < (1<<16) or more.


I've also cleaned up the patch to put the unions as typedefs, and also 
fixed some indentation problems.

Sorry in advance if I can't be responsive to address any comment made to 
the code, as I don't have any Internet access where the PPC machine is :-(.

Guillaume
