Function core::arch::x86_64::_mm256_mask_max_epu64

pub unsafe fn _mm256_mask_max_epu64(
    src: __m256i,
    k: __mmask8,
    a: __m256i,
    b: __m256i
) -> __m256i

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

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86-64 only.

Compare packed unsigned 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).
