[FFmpeg-devel] [PATCH 00/11] DCA DSP changes

[Christophe Gisquet]

There are 3 main modifications that have impact beyond x86:
- int8x8_fmul_int32 can either be an inline function or
  called through the dsp context;
- lfe_dir cases have been split because it is overly complex
  to optimize otherwise;
- synth filter float is rewritten so that the imdct calls are done
  in C, as function calls are overly complex using x86 asm

All patches pass fate-dts. Simple cherry-picking of the libav-based
code to validate with fate, license boiler-plate & co not updated.

Christophe Gisquet (11):
  dcadsp: add int8x8_fmul_int32 to dsp context
  x86: dcadsp: implement int8x8_fmul_int32
  dcadsp: split lfe_dir cases
  x86: dcadsp: implement SSE lfe_dir
  dca dsp C: factorize scaling in lfe_fir
  dcadsp: scan linearly coeffs instead.
  x86: synth filter float: implement SSE2 version
  dcadsp: split synth_filter_float
  dca: replace some memcpy by AV_COPY128
  dca: factorize scaling in inverse ADPCM
  x86: float dsp: unroll SSE versions
