[FFmpeg-devel] [PATCH 0/5] Provide optimized neon implementation

[Hubert Mazur]

Fix minor issues in the patches.
Regarding vsse16 I didn't change saba & umlal to sub & smlal.
It doesn't affect the performance, so left it as it was.
The majority of changes refer to nsse16:
 - fixed indentation (thanks for pointing out),
 - applied the patch from Martin which fixes the balance
   within instructions,
 - interleaved instructions - apparently this helped a little
   to achieve better benchmarks.

I have also updated the benchmark results for each function -
not a huge performance improvement, but worth the effort.
For nsse and vsse are shown below (these are the biggest changes).
 - vsse16 asm from 64.7 to 59.2,
 - nsse16 asm from 120.0 to 116.5.
