Function core::arch::x86::_mm256_mask_testn_epi32_mask

pub unsafe fn _mm256_mask_testn_epi32_mask(
    k: __mmask8, 
    a: __m256i, 
    b: __m256i
) -> __mmask8

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

Available on x86 and target feature avx512f,avx512vl only.

Compute the bitwise NAND of packed 32-bit integers in a and b, producing intermediate 32-bit values, and set the corresponding bit in result mask k (subject to writemask k) if the intermediate value is zero.
