Function core::arch::x86::_mm512_mask_testn_epi64_mask

pub unsafe fn _mm512_mask_testn_epi64_mask(
    k: __mmask8,
    a: __m512i,
    b: __m512i
) -> __mmask8

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

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

Compute the bitwise NAND of packed 64-bit integers in a and b, producing intermediate 64-bit values, and set the corresponding bit in result mask k (subject to writemask k) if the intermediate value is zero.
