void LPPassManager::cloneBasicBlockSimpleAnalysis	(	BasicBlock *	From,
		BasicBlock *	To,
		Loop *	L
	)

SimpleAnalysis - Provides simple interface to update analysis info maintained by various passes. Note, if required this interface can be extracted into a separate abstract class but it would require additional use of multiple inheritance in Pass class hierarchy, something we are trying to avoid. cloneBasicBlockSimpleAnalysis - Invoke cloneBasicBlockAnalysis hook for all passes that implement simple analysis interface.

cloneBasicBlockSimpleAnalysis - Invoke cloneBasicBlockAnalysis hook for all loop passes.
