Function core::arch::x86::_mm_bitshuffle_epi64_mask

pub unsafe fn _mm_bitshuffle_epi64_mask(b: __m128i, c: __m128i) -> __mmask16

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

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