Diego Biurrun	e69364b700	Mark code parts that cannot work on AMD64 due to broken relocations as such.

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
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	1d7c111856	10l Originally committed as revision 6704 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
Michael Niedermayer	68a205edef	dehack *ps_state indexing in the branchless decoder Originally committed as revision 6683 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Guillaume Poirier	a0490b324a	adds some useful comments after some of the #else, #elseif, #endif preprocessor directives to make it clearer which code block depends on which #define xx Originally committed as revision 6668 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Diego Biurrun	c26abfa541	Rename ABS macro to FFABS. Originally committed as revision 6666 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	1f4d5e9f69	slightly faster on P3 slightly slower on athlon and probably faster on P4 Originally committed as revision 6663 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	2b5269b51c	moving lps state transition code a little up in the branched asm code (1% faster on P3) Originally committed as revision 6658 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	b99f3cabed	write cabac low and range variables as early as possible to prevent stalls from reading them before they where written, the P4 is said to disslike that alot, on P3 its 2% faster (START/STOP_TIMER over decode_residual) Originally committed as revision 6657 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d17faef011	use ecx instead of cl (no speed change on P3 but might avoid partial register stalls on some cpus) Originally committed as revision 6656 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d61c4e731e	make state transition tables global as they are constant and the code is slightly faster that way Originally committed as revision 6655 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	5f3eca121e	10l Originally committed as revision 6654 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	0fa352c7e6	make lps_range a global table its constant anyway (saves 1 addition for accessing it) Originally committed as revision 6653 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	3650b43959	enable CMOV_IS_FAST as its faster or equal speed on every cpu (duron, athlon, PM, P3) from which ive seen benchmarks, it might be slower on P4 but noone has posted benchmarks ... Originally committed as revision 6652 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
