class DDGEdge

Declaration

class DDGEdge : public DGEdge { /* full declaration omitted */ };

Description

Data Dependency Graph Edge. An edge in the DDG can represent a def-use relationship or a memory dependence based on the result of DependenceAnalysis. A rooted edge connects the root node to one of the components of the graph.
