The following revision refers to this bug:
https://chromium.googlesource.com/libyuv/libyuv.git/+/cc33dc68c7ce7e20e820b5519989ea18a73f5113
commit cc33dc68c7ce7e20e820b5519989ea18a73f5113
Author: Frank Barchard <fbarchard@google.com>
Date: Fri Feb 12 18:26:10 2016
Port I411ToARGBRow to AVX2.
An SSSE3 version already exists, and an AVX2 version is available for
Visual C. This ports the function to AVX2 completing the AVX2 ports of
all YUV to RGB functions for AVX2 on gcc.
