Function core::arch::x86::_mm_mask_cmp_epu64_mask

pub unsafe fn _mm_mask_cmp_epu64_mask(
    k1: __mmask8,
    a: __m128i,
    b: __m128i,
    const IMM3: _MM_CMPINT_ENUM
) -> __mmask8

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

Available on (x86 or 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).
