Member Function Documentation

◆ begin()

iterator mlir::CallGraph::begin ( ) const
inline

◆ dump()

void CallGraph::dump ( ) const

Dump the graph in a human readable format.

Definition at line 174 of file CallGraph.cpp.

References print().

◆ end()

iterator mlir::CallGraph::end ( ) const
inline

◆ eraseNode()

void CallGraph::eraseNode ( CallGraphNode node)

Erase the given node from the callgraph.

◆ getExternalCallerNode()

CallGraphNode* mlir::CallGraph::getExternalCallerNode ( ) const
inline

Return the callgraph node representing an external caller.

Referenced by llvm::GraphTraits< const mlir::CallGraph * >::getEntryNode(), and print().

◆ getOrAddNode()

CallGraphNode * CallGraph::getOrAddNode ( Region region,
CallGraphNode parentNode 
)

Get or add a call graph node for the given region.

parentNode corresponds to the direct node in the callgraph that contains the parent operation of region, or nullptr if there is no parent node.

CallGraphNode* mlir::CallGraph::getUnknownCalleeNode ( ) const
inline

Return the callgraph node representing an indirect callee.

◆ lookupNode()

CallGraphNode * CallGraph::lookupNode ( Region region) const

Lookup a call graph node for the given region, or nullptr if none is registered.

Definition at line 135 of file CallGraph.cpp.

◆ print()

void CallGraph::print ( raw_ostream &  os) const

◆ resolveCallable()

CallGraphNode * CallGraph::resolveCallable ( CallOpInterface  call,
SymbolTableCollection symbolTable 
) const

Resolve the callable for given callee to a node in the callgraph, or the external node if a valid node was not resolved.

Resolve the callable for given callee to a node in the callgraph, or the unknown callee node if a valid node was not resolved.

The provided symbol table is used when resolving calls that reference callables via a symbol reference.
