Function core::arch::x86_64::_mm_alignr_epi32

pub unsafe fn _mm_alignr_epi32(
    a: __m128i, 
    b: __m128i, 
    const IMM8: i32
) -> __m128i

🔬 This is a nightly-only experimental API. (stdsimd #48556)

Available on x86-64 and target feature avx512f,avx512vl only.

Concatenate a and b into a 32-byte immediate result, shift the result right by imm8 32-bit elements, and store the low 16 bytes (4 elements) in dst.
