Function core::arch::x86::_mm256_maskz_cvtepu8_epi64

pub unsafe fn _mm256_maskz_cvtepu8_epi64(k: __mmask8, a: __m128i) -> __m256i

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

Available on x86 and target feature avx512f,avx512vl only.

Zero extend packed unsigned 8-bit integers in the low 4 bytes of a to packed 64-bit integers, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
