johnplatts commented 2 months ago

The BitShuffle op was added as AVX3_DL/PPC8/PPC9/PPC10/Z14 have instructions that can extract the bits at specified indices from each lane of an U64 or I64 vector.

The BitShuffle op can be used to speed up the Pack operation in hwy/contrib/bit_pack/bit_pack-inl.h on AVX3_DL/PPC/Z14.
