Function _mm512_mask_inserti64x4

pub unsafe fn _mm512_mask_inserti64x4<const IMM8: i32>(
    src: __m512i,
    k: u8,
    a: __m512i,
    b: __m256i,
) -> __m512i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 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 writemask k (elements are copied from src when the corresponding mask bit is not set).
