Function no_std_compat::arch::x86_64::_mm256_maskz_alignr_epi8

pub unsafe fn _mm256_maskz_alignr_epi8<const IMM8: i32>(
    k: u32,
    a: __m256i,
    b: __m256i,
) -> __m256i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 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 zeromask k (elements are zeroed out when the corresponding mask bit is not set).
