Diego Biurrun	15e35274d8	Rename SIGN macro to the more fitting UNFOLD. Originally committed as revision 6626 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Diego Biurrun	0bc2e7f081	BRANCHLESS_CABAD --> BRANCHLESS_CABAC_DECODER Originally committed as revision 6623 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Guillaume Poirier	ab5a1435ec	Move TRANSPOSE8 macro to dsputil_altivec.h. (was duplicated in libavcodec/ppc/vc1dsp_altivec.c nd libavcodec/ppc/mpegvideo_altivec.c, and will be used in upcoming routines for h264_altivec.c) Originally committed as revision 6621 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	9ed92c65f1	moving another bit&1 out, this is as fast as with it in there, but it makes more sense with it outside of the loop Originally committed as revision 6618 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	f1b37db48d	move the &1 out of the asm so gcc can optimize it away in inlined cases (yes this is slightly faster) Originally committed as revision 6616 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	ab0151d163	replace a few and/sub/... by cmov this is faster on P3, should be faster on AMD, and should be slower on P4 its disabled by default (benchmarks welcome so we know when to enable it) Originally committed as revision 6615 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	a6672acf45	reading 8bit mem into a 8bit register needs 2 uops on P4, 8bit->32bit with zero extension needs just 1 Originally committed as revision 6612 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
