Detailed Description

Encodes adjacency information for the deparser. Nodes represent fields or constants that get deparsed. A forward edge from n1 to n2 (and a back edge from n2 to n1) exists if n1 is deparsed right before n2 is deparsed.

Member Function Documentation

◆ addConst()

DeparseGraph::Node DeparseGraph::addConst ( const IR::Constant * c )

Returns: a fresh internal node for representing a deparsed constant.

◆ addEdge()

bool DeparseGraph::addEdge	(	Node	src,
		Node	dst )

Adds an edge from src to dst.

Returns: true if a new edge is created as a result.

◆ addField()

DeparseGraph::Node DeparseGraph::addField ( const PHV::Field * f )

Returns: the internal node corresponding to the given field, creating the node if one doesn't already exist.

◆ nodesBetween()

const std::vector< DeparseGraph::NodeInfo > DeparseGraph::nodesBetween	(	const PHV::Field *	f1,
		const PHV::Field *	f2 ) const

Returns: a description of all nodes that might be deparsed between f1 and f2.
