Function _mm_mask_alignr_epi8

pub unsafe fn _mm_mask_alignr_epi8<const IMM8: i32>(
    src: __m128i,
    k: u16,
    a: __m128i,
    b: __m128i,
) -> __m128i

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

Available on x86 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).
