Function core::arch::x86::_mm512_maskz_cvtepi32_epi64

pub unsafe fn _mm512_maskz_cvtepi32_epi64(k: __mmask8, a: __m256i) -> __m512i

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

Available on x86 and target feature avx512f only.

Sign extend packed 32-bit integers in 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).
