Can we see the template instantiated code by C++ compiler

Question

is there a way to know the compiler instantiated code for a template function or a class in C++

Assume I have the following piece of code

template &l         


        

Answer 1

I think c++ Insights is what you want.

Answer 2

Now there is an on-line tool which does this for you: https://cppinsights.io/ For example, this code

template<class X, class Y> auto add(X x, Y y) {
  return x + y;
}

int main()
{
  return add(10, 2.5);
}

Is translated to

template<class X, class Y> auto add(X x, Y y) {
  return x + y;
}

/* First instantiated from: insights.cpp:9 */
#ifdef INSIGHTS_USE_TEMPLATE
template<>
double add<int, double>(int x, double y)
{
  return static_cast<double>(x) + y;
}
#endif


int main()
{
  return static_cast<int>(add(10, 2.5));
}
