Function core::arch::x86_64::_mm256_mask_max_epi64

pub unsafe fn _mm256_mask_max_epi64(
    src: __m256i, 
    k: __mmask8, 
    a: __m256i, 
    b: __m256i
) -> __m256i

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

This is supported on x86-64 and target feature avx512f,avx512vl only.

Compare packed signed 64-bit integers in a and b, and store packed maximum values in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
