Synopsis

Declared in <llvm/Analysis/DDG.h>

class DDGEdge
    : public DDGEdgeBase

Description

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.

Name	Description
`DDGEdge` [constructor]	Copy-construct a DDG edge from `E.`
`DDGEdge` [constructor]	Move-construct a DDG edge from `E.`
`DDGEdge` [constructor] [deleted]	Deleted constructor; every edge must specify a kind.
`DDGEdge` [constructor]	Construct an edge to `N` of kind `K.`
`operator=`	Copy-assign this DDG edge from `E.`
`operator=`	Move-assign this DDG edge from `E.`
`getKind`	Get the edge kind.
`isDefUse`	Return true if this is a def-use edge, and false otherwise.
`isMemoryDependence`	Return true if this is a memory dependence edge, and false otherwise.
`isRooted`	Return true if this is an edge stemming from the root node, and false otherwise.
