Function core::arch::x86::_mm256_mask_bitshuffle_epi64_mask

pub unsafe fn _mm256_mask_bitshuffle_epi64_mask(
    k: __mmask32,
    b: __m256i,
    c: __m256i
) -> __mmask32

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512bitalg,avx512vl only.

Considers the input b as packed 64-bit integers and c as packed 8-bit integers. Then groups 8 8-bit values from cas indices into the bits of the corresponding 64-bit integer. It then selects these bits and packs them into the output.

Uses the writemask in k - elements are zeroed in the result if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
