[cfe-dev] Incorrect location of a friend declaration

    Through testing I found out that Clang considers the entity at line 11 a function redeclaration so I am able to get the correct line number by iterating through redeclarations. I guess it's not a bug after all.

 If I understand correctly you think that FunctionDecl at line 8 should point to line 11? That doesn't seem right, what you have at line 8 really is a function declaration. What you have at line 11 is the definition of previously declared function.

    Hi all,
    I have the following header:

    class Class1

    class Class2
        friend inline const Class1 operator+(const Class1& f1, const Class1& f2);

    inline const Class1 operator+(const Class1& f1, const Class1& f2)
        return Class1();

    Decl::getLocation() returns line 8 for the friend - that's correct. But it returns 8 for the friend declaration, that is, the function itself, too, while the function is actually located at line 11. If the friend is deleted, then the correct location is reported.
    I think it's a bug so I filed it at https://llvm.org/bugs/show_bug.cgi?id=23401 . But I may me wrong so I'd appreciate your opinion.
