Function _mm512_alignr_epi8

Source
pub unsafe fn _mm512_alignr_epi8<const IMM8: i32>(
    a: __m512i,
    b: __m512i,
) -> __m512i
🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Expand description

Concatenate pairs of 16-byte blocks in a and b into a 32-byte temporary result, shift the result right by imm8 bytes, and store the low 16 bytes in dst. Unlike _mm_alignr_epi8, _mm256_alignr_epi8 functions, where the entire input vectors are concatenated to the temporary result, this concatenation happens in 4 steps, where each step builds 32-byte temporary result.
