Context:
I'm working on a more correct implementation of the C++ name
mangling for Linux/OSX. This is needed for the integration with
C++/STL.
------------------------------------------------------------
Problem 1:
----------
In the following D code 'Expression' is a D class, 'foo' is a C++
function, its argument must be mangled as a pointer to Expression
because D has reference semantic (whereas C++ has value semantic).
class Expression;
extern(C++) void foo(Expression);
Question:
---------
- How to I get the linkage for Expression from a FunDeclaration?
This will ensure the added indirection is put only for the D
classes, not the C++ ones. I tried looking at Parameter,
ClassDeclaration or TypeClass but couldn't find it.
------------------------------------------------------------
Problem 2:
----------
Template arguments that are of basic types are mangled in a
special way which requires to understand which 'int' is which.
extern(C++) A foo(A, B)(B, A, B);
static assert(foo!(int,int).mangleof ==
"_Z3fooIiiET_T0_S0_S1_");
In the example above the first 'int' is not the same as the
second one, it's a distinct substitution.
Question:
---------
- How can I know which is which since from the AST perspective,
the FunDeclaration's Parameters are just TypeBasic 'int'?
------------------------------------------------------------
Thx in advance!
