Here is the call graph for this function:

DepDFSet & OA::Activity::DepDFSet::compose ( DataFlow::DataFlowSet & other )

If <a,b> in *this and <b,c> in other then add <a,c> to *this.

Composes dep pairs in this with other DepDFSet and stores result in this.

Examples: let <b,b> has been removed from set2 with removeDep this other result set1 set2 <use1,def1> <use2,def2> <a,b> <b,a> <a,a> explicitly represented but marked as implicitly blocked <a,b> shouldn't have <a,b> unless <b,b> is explicit in set 2 Unions mImplicitRemoves for this and other

Assumes that getDefsIterator and getUsesIterator handles the mImplicitRemoves correctly. In other words those iterators will return reflexive uses and defs unless the given parameters overlap with something in the implicitRemoves list.

A use or def must be in both for them to be in a result. In the sets, an intersection is done as well.

Here is the call graph for this function:

void OA::Activity::DepDFSet::insertDep	(	OA_ptr< Location >	use,
		OA_ptr< Location >	def
	)

Inserts a dep pair <use,def> into the set of Deps.

The reflexive pairs (eg. <a,a>) are implicitly assumed in the datastructure unless they have been explicitly removed with removeImplicitDep. If they have, calling this routine will take them out of removeImplicitDep. This comes about when a statement such as (a = a + b) occurs. a still depends on itself because it is on the rhs and lhs.
