#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub const fn _mm256_testn_epi32_mask(a: __m256i, b: __m256i) -> __mmask8Compute 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 if the intermediate value is zero.
