# Function core::arch::x86_64::_mm256_mask_alignr_epi8
[−][src]

    pub unsafe fn _mm256_mask_alignr_epi8(
        src: __m256i,
        k: __mmask32,
        a: __m256i,
        b: __m256i,
        imm8: i32
    ) -> __m256i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512bw,avx512vl` 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 using writemask k (elements are copied from src when the corresponding mask bit is not set).
