Function core::arch::x86_64::_mm512_mask_cvtepi64_epi8

pub unsafe fn _mm512_mask_cvtepi64_epi8(
    src: __m128i, 
    k: __mmask8, 
    a: __m512i
) -> __m128i

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

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

Convert packed 64-bit integers in a to packed 8-bit integers with truncation, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
