[cfe-dev] Finding all references to a function overload or type.

[Holtgrewe, Manuel]

Dear all,

I would like to use the clang infrastructure (libclang, libtooling, ...) to find all references to a function overload or a type in a program. This should also work if the program has templates.

Consider the following example:

void f(int i)
{}

template <typename T>
void f(T x)
{
  X<T> y;
}

template <typename T>
struct X
{};

template <>
struct X<long>
{};

main ()
{
  f(3.0);
  f(1);
  f(1l);

  return 0;
}

For example, I would like to find all occurences of the overload "void f(int i)" (result should be the line with "f(1)" or all occurences of the specialization "X<long>" (in the line with "X<T> y" when f is called with a long value.

Is this possible with clang? If so, can anyone point me in the right direction?

Thanks,
Manuel
