* 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>

* x86/swr: replace sse4 instructions in pack_6ch with sse onesJames Almer2014-11-06
| | | | | | | | | There's no benefit from using blendps here except on CPUs with AVX, where it's faster than shufps according to Intel's documentation.

* swr: rewrite resample_common/linear_float_sse/avx in yasm.Ronald S. Bultje2014-06-28
| | | | | | | | | | | 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.

* swr: split out DSP functions.Ronald S. Bultje2014-06-14
| | | | | | | | | | DSP bits of swri_resample go into their own mini-DSP functions; DSP init goes from a per-call branch in multiple_resample to a proper DSP init routine; x86 bits go into x86/; swri_resample() moves out of resample_template.c into resample.c because it's independent of DSP code or sample type; multiple_resample() is simplified.
