Function core::arch::x86::_mm_mask_cvtepi32_epi64

pub unsafe fn _mm_mask_cvtepi32_epi64(
    src: __m128i,
    k: __mmask8,
    a: __m128i
) -> __m128i

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

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

Sign extend packed 32-bit integers in a to packed 64-bit integers, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
