当我编译以下测试代码时，我收到此警告：
test.cu(49): warning: missing return statement at end of non-void function "AllocateSize<T,D>(size_t) noexcept [with T=int, D=Device::GPU]"
detected during instantiation of "Pointer<T, D> AllocateSize<T,D>(size_t) noexcept [with T=int, D=Device::GPU]"
(61): here
我应该担心吗，这是预期的吗？我该怎么做才能让它消失？这看起来很奇怪，因为 cuda 确实支持 C++17。提前致谢！
编译： nvcc -std=c++17 test.cu -o test
测试代码（test.cu）：
enum class Device { CPU, GPU }; // Device
template <typename T, Device D>
class Pointer {
private:
T* m_raw = nullptr;
public:
__host__ __device__ inline Pointer(T* const p) noexcept { this->SetPointer(p); }
__host__ __device__ inline void SetPointer(const …
