CallGraph (Module &M)
CallGraph (CallGraph &&Arg)
~CallGraph ()
void print (raw_ostream &OS) const
void dump () const

Returns the module the call graph corresponds to.

const CallGraphNode * operator[] (const Function *F) const
Returns the call graph node for the provided function.
CallGraphNode * operator[] (const Function *F)
Returns the call graph node for the provided function.
CallGraphNode * getExternalCallingNode () const
Returns the CallGraphNode which is used to represent undetermined calls into the callgraph.
CallGraphNode * getCallsExternalNode () const
void ReplaceExternalCallEdge (CallGraphNode *Old, CallGraphNode *New)
Old node has been deleted, and New is to be used in its place, update the ExternalCallingNode.
Function * removeFunctionFromModule (CallGraphNode *CGN)
Unlink the function from this module, returning it.
CallGraphNode * getOrInsertFunction (const Function *F)
Similar to operator[], but this will insert a new CallGraphNode for F if one does not already exist.
void populateCallGraphNode (CallGraphNode *CGN)
Populate CGN based on the calls inside the associated function.
void addToCallGraph (Function *F)
Add a function to the call graph, and link the node to all of the functions that it calls.

The basic data container for the call graph of a [Module](classllvm%5F1%5F1Module.html "A Module instance is used to store all the information related to an LLVM module.") of IR.

This class exposes both the interface to the call graph for a module of IR.

The core call graph itself can also be updated to reflect changes to the IR.
