[LLVMdev] Supporting Classes using OCaml.

[Frank White]

Hello all...

I'm trying to create a simple language that supports classes using the
OCaml API.

When I use the web page demo to produce the intermediate code for the
following C++ example ...

class MyClass {
 public:
   MyClass();
   int c;
};

MyClass::MyClass () {
 c=55;
}

...I get something like this ....

%class.MyClass = type { i32 }

@MyClass::MyClass() = alias void (%class.MyClass*)* @MyClass::MyClass()
define void @MyClass::MyClass()(%class.MyClass* %this) unnamed_addr
nounwind uwtable align 2 {
  %1 = alloca %class.MyClass*, align 8
  store %class.MyClass* %this, %class.MyClass** %1, align 8
  %2 = load %class.MyClass** %1
  %3 = getelementptr inbounds %class.MyClass* %2, i32 0, i32 0
  store i32 55, i32* %3, align 4
  ret void
}

...however I didn't see any function in the API that generates the named
type command that is produced in the result.

Is there an OCaml function which emits code for named structure types?  Or
this there a means of obtaining an equivalent result.  Any comments would
be greatly appreciated.

Thanks,
Frank
