[LLVMdev] Accessing a function's arguments

[Brian Ensink]

I am trying to generate a simple wrapper function: 

    Function* pWrapper = m_module.getOrInsertFunction(name, 
       FunctionType::get(Type::VoidTy, 
	 vector<const Type*>(1, PointerType::get(Type::IntTy)), false));

How do I actually get the Value* for the one argument to this function?
The pWrapper->getArgumentList().size() is 0. Shouldn't the argument list  
contain the Value* for the parameter?

    DEBUG(pWrapper->dump(););
    DEBUG(pWrapper->getFunctionType()->dump());
    DEBUG(cerr << "number of arguments: " << pWrapper->getArgumentList().size() << endl;);

The debug code above prints as below:

    declare void %foo(int*)
    void (int *)
    number of arguments: 0
