# 1.27.0[−][src]Function core::arch::x86_64::_mm256_unpacklo_epi32

    pub unsafe fn _mm256_unpacklo_epi32(a: __m256i, b: __m256i) -> __m256i

This is supported on x86-64 and target feature `avx2` only.

Unpacks and interleave 32-bit integers from the low half of each 128-bit lane of `a` and `b`.

    #[cfg(target_arch = "x86")]
    use std::arch::x86::*;
    #[cfg(target_arch = "x86_64")]
    use std::arch::x86_64::*;

    let a = _mm256_setr_epi32(0, 1, 2, 3, 4, 5, 6, 7);
    let b = _mm256_setr_epi32(0, -1, -2, -3, -4, -5, -6, -7);

    let c = _mm256_unpacklo_epi32(a, b);

    let expected = _mm256_setr_epi32(0, 0, 1, -1, 4, -4, 5, -5);
    assert_eq!(_mm256_movemask_epi8(_mm256_cmpeq_epi8(c, expected)), !0);
