# Function core::arch::x86_64::_mm512_alignr_epi64[−][src]

    pub unsafe fn _mm512_alignr_epi64(a: __m512i, b: __m512i, imm8: i32) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.

Concatenate a and b into a 128-byte immediate result, shift the result right by imm8 64-bit elements, and store the low 64 bytes (8 elements) in dst.
