Detailed Description
LLVM Argument representation.A class to represent an incoming formal argument to a Function. An argument is a very simple Value. It is essentially a named (optional) type. When used in the body of a function, it represents the value of the actual argument the function was called with.

Constructor & Destructor Documentation
Argument ctor - If Function argument is specified, this argument is inserted at the end of the argument list for the function.
