Function core::arch::x86::_mm_mask_cvtsepi64_storeu_epi8

pub unsafe fn _mm_mask_cvtsepi64_storeu_epi8(
    mem_addr: *mut i8, 
    k: __mmask8, 
    a: __m128i
)

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

This is supported on x86 and target feature avx512f,avx512vl only.

Convert packed signed 64-bit integers in a to packed 8-bit integers with signed saturation, and store the active results (those with their respective bit set in writemask k) to unaligned memory at base_addr.
