# Function core::arch::x86_64::_mm512_alignr_epi8[−][src]

    pub unsafe fn _mm512_alignr_epi8(a: __m512i, b: __m512i, imm8: i32) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512bw` only.

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.
