Convert PQ 4 bit code to dynamic dispatch

Open mdouze opened this issue 8 months ago • 4 comments

Summary: Migration of the 4-bit codecs to dynamic dispatch.

The migration consists in:

  • templatizing the SIMD ResultHandlers to the SIMDLevel
  • instantiating the AVX2 and AVX512 code in their own files (compile units)
  • removing any SIMD dependency from IndexFastScan and IndexIVFFastScan
  • adding dispatching code for the SIMD code
