Function core::arch::x86::_mm_mask_cmpeq_epi64_mask

pub unsafe fn _mm_mask_cmpeq_epi64_mask(
    k1: __mmask8, 
    a: __m128i, 
    b: __m128i
) -> __mmask8

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

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

Compare packed 64-bit integers in a and b for equality, and store the results in mask vector k using zeromask k1 (elements are zeroed out when the corresponding mask bit is not set).
