Function _mm256_maskz_expand_epi64

pub unsafe fn _mm256_maskz_expand_epi64(k: u8, a: __m256i) -> __m256i

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

Available on x86-64 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).
