Function core::arch::x86_64::_mm_mask_cvtsepi64_epi8

pub unsafe fn _mm_mask_cvtsepi64_epi8(
    src: __m128i,
    k: __mmask8,
    a: __m128i
) -> __m128i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

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