How to verify that templated code is copy pasted with type

Question

Hi

I have a template function. I just need to verify what compiler generates (both functions with called type) in some intermediate output files of compile process.

How to verify this ?

Ketan Lalcheta Try checking these posts on Stackoverflow. Sounds like you may want some combination of type_traits and/or concepts
👉 std::invocable
👉 std::is_invocable<Callable, Args...>
👉 std::is_convertible<std::function<Signature>, ...>
👉 std::is_same or std::enable_if with decltype() or declvalue()

Nope Shardis Wolfe

I was not looking for this.

Let me describe what I am looking for.

I have a template function as below:

template <typename T>
void display(T arg)
{
cout << arg << endl;
}

Now , I want to verify( by looking into some generated file by compilers ) that
1. This function is not available until display is not called
2. This function with T as int is available only if display(1) is called.
3. This function with T as double is available only if display(1.2) is called.

Is there an option to verify the intermediate files which compiler generates ?
