getModRefInfo() [1/2]

ModRefInfo ScopedNoAliasAAResult::getModRefInfo	(	const CallBase *	Call,
		const MemoryLocation &	Loc,
		AAQueryInfo &	AAQI )

invalidate()

bool llvm::ScopedNoAliasAAResult::invalidate ( Function & , const PreservedAnalyses & , FunctionAnalysisManager::Invalidator &  )

inline

Handle invalidation events from the new pass manager.

By definition, this result is stateless and so remains valid.
