pub unsafe fn _mm_testn_epi64_mask(a: __m128i, b: __m128i) -> u8🔬This is a nightly-only experimental API. (
stdarch_x86_avx512)Available on 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.
