Detailed Description
Declaration of InstructionReferenceManager class.
The instruction reference handles references to instructions.
The design consists of 3 classes:
InstructionReferenceManager: a single high-level object. Contains the external interface, maps to locate a reference to an instruction based on instruction, and ways to iterate over all instruction references.
InstructionReference: The class which is shown to a client. Encapsulates a reference into a single instruction. Multiple InstructionReferences may point to a single instruction and these can be freely copied etc. You should not use pointers to these classes, but always copy your existing objects with copy constructor/assignment into the new one when returning from functions etc.
InstructionReferenceImpl: This is internal intermediate implementation class. It is not shown to the user. There is always exactly one InstructionReferenceImpl per target instruction. If two instruction references that originally pointed to different instructions (and so had different InstructionReferenceImpl objects), these objects are automatically merged and all the internal pointers and bookkeeping updated accordingly.
Multiple instructionreferences typically point to InstructionReferenceImpl, and instructionReferenceImpl contains pointers to all of these, so it can notify them in case the instructionReferenceImpl is merged with another.
