Function core::arch::x86_64::_mm_mask_and_epi64

pub unsafe fn _mm_mask_and_epi64(
    src: __m128i, 
    k: __mmask8, 
    a: __m128i, 
    b: __m128i
) -> __m128i

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

This is supported on x86-64 and target feature avx512f,avx512vl only.

Compute the bitwise AND of 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).
