virtual void llvm::LoopPass::cloneBasicBlockAnalysis	(	BasicBlock *	F,
		BasicBlock *	T,
		Loop *	L
	)			[inline, virtual]

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. Each loop pass can override these simple analysis hooks to update desired analysis information. cloneBasicBlockAnalysis - Clone analysis info associated with basic block.
