Detailed Description
A user defined p-code op that has a dynamically defined procedure.
The behavior of this op on constant inputs can be dynamically defined. This class defines a unify() method that picks out the input varnodes to the operation, given the root PcodeOp. The input varnodes would generally just be the input varnodes to the raw CALLOTHER after the constant id, but skipping, reordering, or other tree traversal is possible.
This class also defines an execute() method that computes the output given constant inputs (matching the format determined by unify()).
