Detailed Description

This file contains the declarations for the subclasses of Constant, which represent the different flavors of constant values that live in LLVM.

Note that Constants are immutable (once created they never change) and are fully shared by structural equivalence. This means that two structurally equivalent constants will always have the same address. Constants are created on demand as needed and never deleted: thus clients don't have to worry about the lifetime of the objects.
