* 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. 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).

* 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.

* swr: move compensation_distance handling to swri_resample caller.Ronald S. Bultje2014-06-02
| | | | | | | | | | | I think there's an off-by-one in terms of the switchpoint where we switch from dst_incr to ideal_dst_incr, I don't think that's a massive issue, but just be aware of that. It's probably trivial to prevent but I don't care. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> I could not reproduce any off by 1 error, results are bit exact (michael)

* Rewrite main resampling loop (common and linear).Ronald S. Bultje2014-06-02
| | | | | | | | | | | | | | | | | This removes a branch at a performance-sensitive point (in the middle of the loop). In fate-swr-resample-s32p-8000-2626, this makes the code about 10% faster. It also simplifies the loops, allowing us to rewrite it in yasm at some later point. The compensation_distance != 0 code and index < 0 code are still kind of hairy. For compensation_distance != 0, this should likely be handled in the caller, so that it calls swri_resample twice (once until the dst_incr switch-point, and once with the remainder of the samples). For index < 0, the code should probably be rewritten to break out of the loop once sample_index >= 0, and then resume (e.g. as a tail-call) to the common or linear resampling loops.
