Function core::arch::x86::_mm_mask_compress_epi64

pub unsafe fn _mm_mask_compress_epi64(
    src: __m128i, 
    k: __mmask8, 
    a: __m128i
) -> __m128i

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

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

Contiguously store the active 64-bit integers in a (those with their respective bit set in writemask k) to dst, and pass through the remaining elements from src.
