[x264-devel] [PATCH] Align dct arrays (Altivec optimization, step 0)

[Guillaume POIRIER]

Hello folks,
In order to reduce the size of my Altivec optimizations patchset, here's 
a patch that just forces the alignment of dct arrays found in 
encoder/macroblock.c
As you probably know, un-aligned memory access are are not implemented 
in hardware, so handling them requires to re-align data in software, 
which is both slower, and undesirable if the data can be aligned.
Note that proper alignment usually improves performance on other archs too.

It also aligns the test arrays as found in tool/checkasm.c.


Please review and comment.

Guillaume
