pub unsafe fn _mm256_testn_epi64_mask(a: __m256i, b: __m256i) -> __mmask8🔬This is a nightly-only experimental API. (
stdarch_x86_avx512 #111137)Available on (x86 or x86-64) and target feature
avx512f,avx512vl and x86 only.Expand description
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 if the intermediate value is zero.
