Function core::arch::x86::_mm512_mask_cmpunord_pd_mask

pub unsafe fn _mm512_mask_cmpunord_pd_mask(
    k1: __mmask8, 
    a: __m512d, 
    b: __m512d
) -> __mmask8

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

Available on x86 and target feature avx512f only.

Compare packed double-precision (64-bit) floating-point elements in a and b to see if either is NaN, and store the results in mask vector k using zeromask k1 (elements are zeroed out when the corresponding mask bit is not set).
