Function core::arch::x86_64::_mm256_mask_cmp_epu64_mask

pub unsafe fn _mm256_mask_cmp_epu64_mask(
    k1: __mmask8, 
    a: __m256i, 
    b: __m256i, 
    const IMM3: _MM_CMPINT_ENUM
) -> __mmask8

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

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

Compare packed unsigned 64-bit integers in a and b based on the comparison operand specified by imm8, and store the results in mask vector k using zeromask k1 (elements are zeroed out when the corresponding mask bit is not set).
