# Function core::arch::x86_64::_mm512_maskz_cvtepi8_epi32[−][src]

    pub unsafe fn _mm512_maskz_cvtepi8_epi32(k: __mmask16, a: __m128i) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.

Sign extend packed 8-bit integers in a to packed 32-bit integers, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
