Classes
class	llvm::FoldingSetBase
	FoldingSetBase - Implements the folding set functionality. More...
class	llvm::FoldingSetBase::Node
	Node - This class is used to maintain the singly linked bucket list in a folding set. More...
struct	llvm::FoldingSetBase::FoldingSetInfo
	Functions provided by the derived class to compute folding properties. More...
struct	llvm::DefaultFoldingSetTrait< T >
	DefaultFoldingSetTrait - This class provides default implementations for FoldingSetTrait implementations. More...
struct	llvm::FoldingSetTrait< T, Enable >
	FoldingSetTrait - This trait class is used to define behavior of how to "profile" (in the FoldingSet parlance) an object of a given type. More...
struct	llvm::DefaultContextualFoldingSetTrait< T, Ctx >
	DefaultContextualFoldingSetTrait - Like DefaultFoldingSetTrait, but for ContextualFoldingSets. More...
struct	llvm::ContextualFoldingSetTrait< T, Ctx >
	ContextualFoldingSetTrait - Like FoldingSetTrait, but for ContextualFoldingSets. More...
class	llvm::FoldingSetNodeIDRef
	FoldingSetNodeIDRef - This class describes a reference to an interned FoldingSetNodeID, which can be a useful to store node id data rather than using plain FoldingSetNodeIDs, since the 32-element SmallVector is often much larger than necessary, and the possibility of heap allocation means it requires a non-trivial destructor call. More...
class	llvm::FoldingSetNodeID
	FoldingSetNodeID - This class is used to gather all the unique data bits of a node. More...
class	llvm::FoldingSetImpl< Derived, T >
	FoldingSetImpl - An implementation detail that lets us share code between FoldingSet and ContextualFoldingSet. More...
class	llvm::FoldingSet< T >
	FoldingSet - This template class is used to instantiate a specialized implementation of the folding set to the node class T. More...
class	llvm::ContextualFoldingSet< T, Ctx >
	ContextualFoldingSet - This template class is a further refinement of FoldingSet which provides a context argument when calling Profile on its nodes. More...
class	llvm::FoldingSetVector< T, VectorT >
	FoldingSetVector - This template class combines a FoldingSet and a vector to provide the interface of FoldingSet but with deterministic iteration order based on the insertion order. More...
class	llvm::FoldingSetIteratorImpl
	FoldingSetIteratorImpl - This is the common iterator support shared by all folding sets, which knows how to walk the folding set hash table. More...
class	llvm::FoldingSetIterator< T >
class	llvm::FoldingSetBucketIteratorImpl
	FoldingSetBucketIteratorImpl - This is the common bucket iterator support shared by all folding sets, which knows how to walk a particular bucket of a folding set hash table. More...
class	llvm::FoldingSetBucketIterator< T >
class	llvm::FoldingSetNodeWrapper< T >
	FoldingSetNodeWrapper - This template class is used to "wrap" arbitrary types in an enclosing object so that they can be inserted into FoldingSets. More...
class	llvm::FastFoldingSetNode
	FastFoldingSetNode - This is a subclass of FoldingSetNode which stores a FoldingSetNodeID value rather than requiring the node to recompute it each time it is needed. More...
struct	llvm::FoldingSetTrait< T * >
struct	llvm::FoldingSetTrait< std::pair< T1, T2 > >
struct	llvm::FoldingSetTrait< T, std::enable_if_t< std::is_enum< T >::value > >

Detailed Description

This file defines a hash set that can be used to remove duplication of nodes in a graph.

This code was originally created by Chris Lattner for use with SelectionDAGCSEMap, but was isolated to provide use across the llvm code set.
