//===-- llvm/GlobalValue.h - Class to represent a global value ---*- C++ -*--=//
|
||
|
//
|
||
|
// This file is a common base class of all globally definable objects. As such,
|
||
|
// it is subclassed by GlobalVariable and by Method. This is used because you
|
||
|
// can do certain things with these global objects that you can't do to anything
|
||
|
// else. For example, use the address of one as a constant.
