Function core::arch::x86::_mm512_maskz_inserti64x4

pub unsafe fn _mm512_maskz_inserti64x4(
    k: __mmask8,
    a: __m512i,
    b: __m256i,
    const IMM8: i32
) -> __m512i

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

Available on (x86 or x86-64) and target feature avx512f only.

Copy a to tmp, then insert 256 bits (composed of 4 packed 64-bit integers) from b into tmp at the location specified by imm8. Store tmp to dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
