Function core::arch::x86_64::_mm_maskz_cvtepi16_epi64

pub unsafe fn _mm_maskz_cvtepi16_epi64(k: __mmask8, a: __m128i) -> __m128i

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

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

Sign extend packed 16-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).
