void CallGraph::getAnalysisUsage ( AnalysisUsage & ) const

virtual

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job. If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.

Reimplemented from llvm::Pass.

Definition at line 65 of file CallGraph.cpp.

Definition at line 135 of file CallGraph.h.

CallGraphNode* llvm::CallGraph::getExternalCallingNode ( ) const

inline

Returns the CallGraphNode which is used to represent undetermined calls into the callgraph.

Module& llvm::CallGraph::getModule ( ) const

inline

getModule - Return the module the call graph corresponds to.

Definition at line 112 of file CallGraph.h.

CallGraphNode * CallGraph::getOrInsertFunction ( const Function * F )

getOrInsertFunction - This method is identical to calling operator[], but it will insert a new CallGraphNode for the specified function if one does not already exist.

Definition at line 173 of file CallGraph.cpp.

References F(), and llvm::GlobalValue::getParent().

CallGraphNode* llvm::CallGraph::getRoot ( )

Return the root/main method in the module, or some other root node, such as the externalcallingnode.

void CallGraph::print	(	raw_ostream &	O,
		const Module *	M
	)		const

virtual

print - Print out the internal state of the pass. This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

Reimplemented from llvm::Pass.

Referenced by dump().

void CallGraph::releaseMemory ( )

virtual

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed. The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.

Optionally implement this function to release pass memory when it is no longer used.

CallsExternalNode is not in the function map, delete it explicitly.

Reimplemented from llvm::Pass.

Function * CallGraph::removeFunctionFromModule ( CallGraphNode * CGN )

removeFunctionFromModule - Unlink the function from this module, returning it. Because this removes the function from the module, the call graph node is destroyed. This is only valid if the function does not call any other functions (ie, there are no edges in it's CGN). The easiest way to do this is to dropAllReferences before calling this.

bool CallGraph::runOnModule ( Module & M )

virtual

runOnModule - Virtual method overriden by subclasses to process the module being operated on.

Implements llvm::ModulePass.
