public abstract class IREnumeration extends Object
It simply serves as a place to collect the implementation of primitive IR enumerations.
None of these functions are meant to be called directly from anywhere except IR, Instruction, and BasicBlock.
General clients should use the higher level interfaces provided by those classes.

NB: start and last _must_ be in the same basic block and must be in the proper relative order. This code does _not_ check this invariant, and will simply fail by eventually thowing a NoSuchElementException if it is not met. Caller's must be sure the invariants are met.
