◆ collectSubRegionBindings() [1/2]

static void collectSubRegionBindings	(	SmallVectorImpl< BindingPair > &	Bindings,
		SValBuilder &	SVB,
		const ClusterBindings &	Cluster,
		const SubRegion *	Top,
		BindingKey	TopKey,
		bool	IncludeAllDefaultBindings
	)

static

Collects all bindings in Cluster that may refer to bindings within Top.

Each binding is a pair whose first is the key (a BindingKey) and whose second is the value (an SVal).

The IncludeAllDefaultBindings parameter specifies whether to include default bindings that may extend beyond Top itself, e.g. if Top is an aggregate within a larger aggregate with a default binding.
