Function core::arch::x86::_mm512_mask_add_epi64

pub unsafe fn _mm512_mask_add_epi64(
    src: __m512i, 
    k: __mmask8, 
    a: __m512i, 
    b: __m512i
) -> __m512i

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

Available on x86 and target feature avx512f only.

Add packed 64-bit integers in a and b, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
