# Date Author Comment
b9c7f66e 01/20/2011 01:34 AM Ronald S. Bultje

Fix horizontal/horizontal_up 8x8l intra prediction x86/simd functions.
The original functions did not work correctly for edge pixels, e.g.
when CODEC_FLAG_EMU_EDGE is set, leading to corrupt output in e.g. VLC.
Based on a patch by Daniel Kang <daniel d kang gmail com>....

ef4a6514 01/18/2011 08:48 PM Mans Rullgard

Replace ASMALIGN with .p2align

This macro has unconditionally used .p2align for a long time and
serves no useful purpose.

19fb234e 01/14/2011 09:34 PM Jason Garrett-Glaser

H.264: split luma dc idct out and implement MMX/SSE2 versions
About 2.5x the speed.

NOTE: the way that the asm code handles large qmuls is a bit suboptimal.
If x264-style dequant was used (separate shift and qmul values), it might
be possible to get some extra speed....

004357a1 01/03/2011 11:30 AM Daniel Kang

Fix compilation on x86-32 with --disable-optimizations,
fixes issue 2127.
