Function core::arch::x86::_mm512_mask_cvtsepi64_epi8

pub unsafe fn _mm512_mask_cvtsepi64_epi8(
    src: __m128i, 
    k: __mmask8, 
    a: __m512i
) -> __m128i

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

This is supported on (non-crate feature miri-test-libstd or test or doctest) and x86 and target feature avx512f only.

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