pub unsafe fn _mm_bitshuffle_epi64_mask(b: __m128i, c: __m128i) -> __mmask16🔬This is a nightly-only experimental API. (
stdarch_x86_avx512 #111137)Available on (x86 or x86-64) and target feature
avx512bitalg,avx512vl and x86-64 only.Expand description
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.
