Function core::arch::x86_64::_mm512_mask_cvtepu8_epi64

pub unsafe fn _mm512_mask_cvtepu8_epi64(
    src: __m512i, 
    k: __mmask8, 
    a: __m128i
) -> __m512i

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

This is supported on x86-64 and target feature avx512f only.

Zero extend packed unsigned 8-bit integers in the low 8 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).
