Function serde::lib::core::arch::x86_64::_mm256_mask_alignr_epi64

pub unsafe fn _mm256_mask_alignr_epi64<const IMM8: i32>(
    src: __m256i,
    k: u8,
    a: __m256i,
    b: __m256i
) -> __m256i

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

Available on x86-64 only.

Concatenate a and b into a 64-byte immediate result, shift the result right by imm8 64-bit elements, and store the low 32 bytes (4 elements) in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
