Classes
class	llvm::SCEV
	This class represents an analyzed expression in the program. More...
struct	llvm::FoldingSetTrait< SCEV >
struct	llvm::SCEVCouldNotCompute
	An object of this class is returned by queries that could not be answered. More...
class	llvm::SCEVPredicate
	This class represents an assumption made using SCEV expressions which can be checked at run-time. More...
struct	llvm::FoldingSetTrait< SCEVPredicate >
class	llvm::SCEVComparePredicate
	This class represents an assumption that the expression LHS Pred RHS evaluates to true, and this can be checked at run-time. More...
class	llvm::SCEVWrapPredicate
	This class represents an assumption made on an AddRec expression. More...
class	llvm::SCEVUnionPredicate
	This class represents a composition of other SCEV predicates, and is the class that most clients will interact with. More...
class	llvm::ScalarEvolution
	The main scalar evolution driver. More...
struct	llvm::ScalarEvolution::ExitLimit
	Information about the number of loop iterations for which a loop exit's branch condition evaluates to the not-taken path. More...
struct	llvm::ScalarEvolution::LoopInvariantPredicate
class	llvm::ScalarEvolution::LoopGuards
class	llvm::ScalarEvolution::FoldID
class	llvm::ScalarEvolutionAnalysis
	Analysis pass that exposes the ScalarEvolution for a function. More...
class	llvm::ScalarEvolutionVerifierPass
	Verifier pass for the ScalarEvolutionAnalysis results. More...
class	llvm::ScalarEvolutionPrinterPass
	Printer pass for the ScalarEvolutionAnalysis results. More...
class	llvm::ScalarEvolutionWrapperPass
class	llvm::PredicatedScalarEvolution
	An interface layer with SCEV used to manage how we see SCEV expressions for values in the context of existing predicates. More...
struct	llvm::DenseMapInfo< ScalarEvolution::FoldID >
