[FFmpeg-devel] [PATCH] fix for roundup issue 2127

[Daniel Kang]

I am a Google Code-In student, and as part of a task, I have written a
fix for: https://roundup.ffmpeg.org/issue2127. The patch compiles with
32/64-bit and --disable-optimizations. It passes "make fate" with and
without --disable-optimizations.

I have ran several timings with and without my patch. The
START/STOP_TIMER was placed around the actual "asm" block in the
transpose4x4 function.
With my patch: 21.32 +/- 0.04 clocks
Without my patch: 21.58 +/- 0.04 clocks

Are there any comments on my patch? If not, can this be committed?
