Function core::arch::x86_64::_mm256_mask_compress_epi64

pub unsafe fn _mm256_mask_compress_epi64(
    src: __m256i,
    k: __mmask8,
    a: __m256i
) -> __m256i

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

Available on (x86 or x86-64) 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.
