* swresample/x86/resample: Remove obsolete MMXEXT functionsAndreas Rheinhardt2022-06-14
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT, SSE and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2). So given that the only systems which benefit from the MMXEXT resamplers (which are overridden by SSE2) are truely ancient 32bit x86s they are removed.

* swresample/x86: add support for exact_rationalMuhammad Faiz2016-06-21
| | | | | | | phase_shift and phase_mask is removed generally exact_rational=on is faster than exact_rational=off Signed-off-by: Muhammad Faiz <mfcc64@gmail.com>
* x86: move XOP emulation code back to x86incJames Almer2015-08-03
| | | | | | | | | | Only two functions that use xop multiply-accumulate instructions where the first operand is the same as the fourth actually took advantage of the macros. This further reduces differences with x264's x86inc. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>

Linear interpolation goes from 63 (llvm) or 58 (gcc) to 48 (yasm) cycles/sample on 64bit, or from 66 (llvm/gcc) to 52 (yasm) cycles/ sample on 32bit. Bon-linear goes from 43 (llvm) or 38 (gcc) to 32 (yasm) cycles/sample on 64bit, or from 46 (llvm) or 44 (gcc) to 38 (yasm) cycles/sample on 32bit (all testing on OSX 10.9.2, llvm 5.1 and gcc 4.8/9).
