Function core::arch::x86_64::_mm256_mask_inserti32x4

pub unsafe fn _mm256_mask_inserti32x4(
    src: __m256i,
    k: __mmask8,
    a: __m256i,
    b: __m128i,
    const IMM8: i32
) -> __m256i

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

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

Copy a to tmp, then insert 128 bits (composed of 4 packed 32-bit integers) from b into tmp at the location specified by imm8. Store tmp to dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
