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.

static void ssa_unfiltered_cfg::DefsAndUsesTraversal::CollectDefsAndUses	(	SgNode *	traversalRoot,
		CFGNodeToVarsMap &	defs,
		std::map< SgNode , std::set< SgVarRefExp > > &	uses
	)

static

Call this method to collect defs and uses for a subtree.

The additional defs and uses discovered in the tree will be inserted in the passed data structures.

virtual ChildUses ssa_unfiltered_cfg::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.
