Function core::arch::x86::_mm_mask_cvtepu16_epi64

pub unsafe fn _mm_mask_cvtepu16_epi64(
    src: __m128i, 
    k: __mmask8, 
    a: __m128i
) -> __m128i

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

Available on x86 and target feature avx512f,avx512vl only.

Zero extend packed unsigned 16-bit integers in the low 4 bytes of 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).
