pub unsafe fn _mm_maskz_expand_epi8(k: __mmask16, a: __m128i) -> __m128i
🔬 This is a nightly-only experimental API. (stdsimd #48556)
Available on x86 and target feature avx512vbmi2,avx512vl only.
Expand description

Load contiguous active 8-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).
