yasm 1.2 build of libyuv #199

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
yasm version of libyuv has 2 advantages

1. 64 bit Windows support.
Visual C does not support inline 64 bit.
64 bit Windows is currently unoptimized C.
Intel C should work, but is untested.
GCC/Clang on Windows should work, but also untested.  MinGW cross build from 
Linux is another way to build 64 bit Windows and get 64 bit assembly.

2. AVX2 support.
AVX2 requires Visual Studio 2012, or GCC 4.7.  With older compilers it is 
unavailable.
Yasm upgrade may be easier for some projects.
