Detailed Description

A class for uniquely labelling and comparing PcodeOps.

Different PcodeOps generated by a single machine instruction can only be labelled with a single Address. But PcodeOps must be distinguishable and compared for execution order. A SeqNum extends the address for a PcodeOp to include:
