pub unsafe fn _mm256_maskz_conflict_epi64(k: __mmask8, a: __m256i) -> __m256i
🔬This is a nightly-only experimental API. (stdsimd #48556)
Available on (x86 or x86-64) and target feature avx512cd,avx512vl and x86 only.
Expand description

Test each 64-bit element of a for equality with all other elements in a closer to the least significant bit using zeromask k (elements are zeroed out when the corresponding mask bit is not set). Each element’s comparison forms a zero extended bit vector in dst.
