Function core::arch::x86::_mm512_mask_testn_epi8_mask

pub unsafe fn _mm512_mask_testn_epi8_mask(
    k: __mmask64, 
    a: __m512i, 
    b: __m512i
) -> __mmask64

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

This is supported on x86 and target feature avx512bw only.

Compute the bitwise NAND of packed 8-bit integers in a and b, producing intermediate 8-bit values, and set the corresponding bit in result mask k (subject to writemask k) if the intermediate value is zero.
