Whilst I am aware that we can now use the single line C++ comment,
would it perhaps be a better idea to stick with the C style comments
just for uniformity?
+ if (arg->ts.type == BT_CLASS)
+ tmp = gfc_vtable_size_get (TREE_OPERAND (argse.expr, 0));
+ tmp = fold_convert (result_type, tmp);
+ goto done;
Is there any possibility that the class object will be adorned by any
kind of reference here? In which case, you should drill down through
the TREE_OPERANDS to find it.
Otherwise, this is OK for trunk.
Thanks for the patch

The knack of flying is learning how to throw yourself at the ground and miss.
