Michael Niedermayer	d3e7c5c35b	1 instruction less Originally committed as revision 6743 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Guillaume Poirier	e7768fc512	Add x86 conditionnal mov (CMOV) "detection" (based on the cpu passed by --cpu=xx) Sets HAVE_CMOV define so we can protect relevant code with #ifdef HAVE_CMOV Originally committed as revision 6742 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	a616db285a	reordering instructions a little in decode_significance_x86() -> 2 instructions less / 1% faster decode_residual on P3 Originally committed as revision 6741 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	13404b2e98	factorize get_cabac asm (0.5% slower but its much cleaner) Originally committed as revision 6740 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Alex Beregszaszi	1e4051aaa0	correct signaling of palette change Originally committed as revision 6739 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Bernhard Rosenkränzer	ba9fb5da3a	Fix PIC compilation, some defines were under #ifdef !PIC but used in the PIC case nevertheless. patch by Bernhard Rosenkranzer, bero arklinux org Originally committed as revision 6738 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d72bc32389	unused variable Originally committed as revision 6737 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Guillaume Poirier	1c5d830c25	10l: Revert bogus use of GCC's -march=xx: Almost all CPU targets use -mcpu=xx to set architecture type, register usage, choice of mnemonics, and instruction scheduling parameters, except x86, MIPS, HPPA which uses -march=xx Originally committed as revision 6736 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	143bf7d7c3	dont mess with ByteIOContext internal variables (fixes showdown2.mov) Originally committed as revision 6733 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
Baptiste Coudurier	99fd05cbdd	use AVFormatContext to log Originally committed as revision 6731 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Guillaume Poirier	38d0a8aad8	rename --tune to --cpu and make --cpu pass the apropriate -march=xx option to the compiler. Note that previous implementation (--tune) wasn't consistent with regards to setting -march/-mcpu/-mtune whereas current --cpu now is Original thread: Date: Oct 17, 2006 3:20 PM (patch) \|\| Date: Oct 13, 2006 12:03 PM (suggestion of configure clean-up) Subject: Re: [Ffmpeg-devel] [PATH] test if cpu supports CMOV Originally committed as revision 6729 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	eb73bf723d	x86 asm version of the decode significance loop (not 8x8) of decode_residual() 5% faster decode_residual() on P3 Originally committed as revision 6724 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
