Michael Niedermayer	e08f580644	decode_significance_8x8_x86() 8% faster decode_cabac_residual() (8x8 case only) on P3 Originally committed as revision 6750 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Guillaume Poirier	94e4c3a333	Protect code that uses CMOV instructions with HAVE_CMOV, Make configure set CMOV_IS_FAST on arches on which cmov has a low latency (typically non-Netburst based processor) Originally committed as revision 6749 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	f624f029f0	slightly faster decode_cabac_mb_mvd() Originally committed as revision 6735 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	aa1da263aa	1 variable less in decode_cabac_residual() no speed change (but less vars means less things gcc can load and store redundantly) Originally committed as revision 6734 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	ebd624b662	optimize sign decoding code in decode_residual() x86 is 4% faster on P3 C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C) ... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all Originally committed as revision 6732 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	faff3a7ad0	this code will not work with PIC as it needs 7 registers and gcc doesnt support that in PIC Originally committed as revision 6703 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	f24a515931	shift CABACContext.range right, this reduces the number of shifts needed in get_cabac() and is slightly faster on P3 (and should be much faster on P4 as the P4 except the more recent variants lacks an integer shifter and so shifts have ~10 times longer latency then simple operations like adds) Originally committed as revision 6702 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
