Function core::arch::x86_64::_mm512_bitshuffle_epi64_mask

pub unsafe fn _mm512_bitshuffle_epi64_mask(b: __m512i, c: __m512i) -> __mmask64

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

This is supported on x86-64 and target feature avx512bitalg 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 the bits of the corresponding 64-bit integer. It then selects these bits and packs them into the output.
