[FFmpeg-devel] [PATCH 00/11] AVX-512 support (v.2)

[James Darnley]

A few changes from last time.  A couple of the patches have notes on them.

I've dropped the patch which added Nasm's smartalign feature which was causing
problems building rv34dsp.asm.  I don't know why.  Eventually I try to look at
it again.

I've also added 3 functions that acutally use ZMM registers.

Henrik Gramner (1):
  x86inc: AVX-512 support

James Darnley (10):
  configure: test whether x86 assembler supports AVX-512
  avutil: add AVX-512 flags
  avutil: detect when AVX-512 is available
  avutil: add alignment needed for AVX-512
  avcodec: add stride alignment needed for AVX-512
  checkasm: support for AVX-512 functions
  avcodec/v210enc: add AVX-512 10-bit line pack function
  avcodec/blockdsp: roll-up x86asm preprocessor loop
  avcodec/blockdsp: add AVX-512 version of clear_block(s)
