pub unsafe fn _mm_maskz_and_epi64(k: __mmask8, a: __m128i, b: __m128i) -> __m128i
🔬 This is a nightly-only experimental API. (stdsimd #48556)
Available on x86-64 and target feature avx512f,avx512vl only.
Expand description

Compute the bitwise AND of packed 64-bit integers in a and b, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
