Constructor & Destructor Documentation

◆ SymbolUserMap()

SymbolUserMap::SymbolUserMap	(	SymbolTableCollection &	symbolTable,
		Operation *	symbolTableOp
	)

Build a user map for all of the symbols defined in regions nested under 'symbolTableOp'.

A reference to the provided symbol table collection is kept by the user map to ensure efficient lookups, thus the lifetime should extend beyond that of this map.

Member Function Documentation

◆ getUsers()

ArrayRef<Operation *> mlir::SymbolUserMap::getUsers ( Operation * symbol ) const

inline

Return the users of the provided symbol operation.

◆ replaceAllUsesWith()

void SymbolUserMap::replaceAllUsesWith	(	Operation *	symbol,
		StringAttr	newSymbolName
	)

Replace all of the uses of the given symbol with newSymbolName.
