Detailed Description

This class collects all the defs and uses associated with each node in the traversed CFG.

Note that this does not compute reachability information; it just records each instance of a variable used or defined.

Definition at line 996 of file VariableRenaming.h.

virtual ChildUses VariableRenaming::DefsAndUsesTraversal::evaluateSynthesizedAttribute	(	SgNode *	node,
		SynthesizedAttributesList	attrs
	)

virtual

Called to evaluate the synthesized attribute on every node.

This function will handle passing all variables that are defined and used by a given operation.

Parameters

node	The node being evaluated.
attr	The attributes from the child nodes.

void VariableRenaming::DefsAndUsesTraversal::addUsesToNode	(	SgNode *	node,
		std::vector< SgNode * >	uses
	)

private

Mark all the uses as occurring at the specified node.

void VariableRenaming::DefsAndUsesTraversal::addDefForVarAtNode	(	SgVarRefExp *	currentVar,
		SgNode *	defNode
	)

private

Mark the given variable as being defined at the node.
