// Test new aarch64 intrinsics with poly128
// FIXME: Currently, poly128_t equals to uint128, which will be spilt into
// two 64-bit GPR(eg X0, X1). Now moving data from X0, X1 to FPR128 will
// introduce 2 store and 1 load instructions(store X0, X1 to memory and
// then load back to Q0). If target has NEON, this is better replaced by
// FMOV or INS.
