Neither of them? Ultimately, the same techniques of composing a vtable for the class are used, but how this is done varies way to wildly, since how it should be done is not at all set in stone. There is a decent explanation of solving the diamond-hierarchy problem here, but, like most of this, it is quite vendor-specific. It's an implementation detail, but no. If an implementation put pointers to non-virtual functions into a vtable it couldn't use these pointers for making function calls because it would often cause incorrect non-virtual functions to be called.
When a non-virtual function is called the implementation must use the static type of the object on which the function is being called to determine the correct function to call. A function stored in a vtable accessed by a vptr will be dependent on the dynamic type of the object, not any static type of a reference or pointer through which it is being accessed.

All good. How does the compiler know f's position in vtable Each vendor will have their own way of doing this, but I always think of the vtable as map of the member function signature to memory offset. A is a virtual base class of B and C The short answer?
Try this: params. Only authorized users can answer the question. Because there are only two virtual functions here, each virtual table will have two entries one for function1 and one for function2. Remember that when these virtual tables are filled out, each entry is filled out with the most-derived function an object of that class type can call. The virtual table for Base objects is simple. An object of type Base can only access the members of Base. Base has no access to D1 or D2 functions.
Consequently, the entry for function1 points to Base::function1 and the entry for function2 points to Base::function2. The virtual table for D1 is slightly more complex. An object of type D1 can access members of both D1 and Base. However, D1 has overridden function1 , making Dfunction1 more derived than Base::function1.
Consequently, the entry for function1 points to Dfunction1. The virtual table for D2 is similar to D1, except the entry for function1 points to Base::function1 , and the entry for function2 points to Dfunction2. The entries in the virtual table point to the most-derived version of the function objects of that class are allowed to call.
