* avcodec/ac3dsp: Remove unused parameterAndreas Rheinhardt2022-09-291-1/+1
| | | | | | Forgotten in fd98594a8831ce037a495b6d7e090bd8f81e83a1. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/x86/ac3dsp_init: Remove obsolete 3dnow, MMX(EXT), SSE functionsAndreas Rheinhardt2022-06-221-18/+0
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/ac3: Move non-(de|en)coder-only parts out of ac3.hAndreas Rheinhardt2022-05-151-1/+0
| | | | | | | | | | Move AC3HeaderInfo into ac3_parser_internal.h and the rest into a new header ac3defs.h. This also breaks an include cycle of ac3.h and ac3tab.h (the latter now only needs ac3defs.h). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| * x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponentsDiego Biurrun2013-04-261-1/+0
| | | | | | | | | | | | | | The function requires increasing the fuzz factor for the ac3/eac3 encode tests and even so makes fate fail. It only provides a slight encoding speedup for legacy CPUs that do not support SS2. Thus its benefit is not worth the trouble it creates and fixing it would be a waste of time.

* | x86/ac3dsp_init: try to workaround ICC failure.Michael Niedermayer2012-12-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | The asm code is not valid for older compilers as it uses too many operands, ICC on x86_32 seems affected by this. This patch disables the affected code for ICC on x86_32 and should make it compileable again. A better fix would be to use fewer operands or to change this code to yasm, later is being worked on AFAIK so this is a temporary solution. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
