Detailed Description

An iterator to transparently surface an operation's def-use dependences from the SSA subgraph (induced by the registered operations), as well as auxiliary, operation-to-operation dependences explicitly provided by the client.

Constructor & Destructor Documentation

DependenceIterator()

DependenceIterator::DependenceIterator	(	Problem &	problem,
		Operation *	op,
		bool	end = false
	)

Construct an iterator over the op's def-use dependences (i.e.

result values of other operations registered in the scheduling problem, which are used by one of op's operands), and over auxiliary dependences (i.e. from other operation to op).

Definition at line 480 of file Problems.cpp.
