Function _mm_maskz_expand_epi64

pub unsafe fn _mm_maskz_expand_epi64(k: __mmask8, a: __m128i) -> __m128i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86 only.

Load contiguous active 64-bit integers from a (those with their respective bit set in mask k), and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
