Classes
struct	llvm::IRSimilarity::IRInstructionData
	This provides the utilities for hashing an Instruction to an unsigned integer. More...
struct	llvm::IRSimilarity::IRInstructionDataList
struct	llvm::IRSimilarity::IRInstructionDataTraits
struct	llvm::IRSimilarity::IRInstructionMapper
	Helper struct for converting the Instructions in a Module into a vector of unsigned integers. More...
struct	llvm::IRSimilarity::IRInstructionMapper::InstructionClassification
	Custom InstVisitor to classify different instructions for whether it can be analyzed for similarity. More...
class	llvm::IRSimilarity::IRSimilarityCandidate
	This is a class that wraps a range of IRInstructionData from one point to another in the vector of IRInstructionData, which is a region of the program. More...
struct	llvm::IRSimilarity::IRSimilarityCandidate::OperandMapping
struct	llvm::IRSimilarity::IRSimilarityCandidate::RelativeLocMapping
	A helper struct to hold the candidate, for a branch instruction, the relative location of a label, and the label itself. More...
class	llvm::IRSimilarity::IRSimilarityIdentifier
	This class puts all the pieces of the IRInstructionData, IRInstructionMapper, IRSimilarityCandidate together. More...
class	llvm::IRSimilarityIdentifierWrapperPass
	An analysis pass based on legacy pass manager that runs and returns IRSimilarityIdentifier run on the Module. More...
class	llvm::IRSimilarityAnalysis
	An analysis pass that runs and returns the IRSimilarityIdentifier run on the Module. More...
class	llvm::IRSimilarityAnalysisPrinterPass
	Printer pass that uses IRSimilarityAnalysis. More...

Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Typedefs
typedef DenseMap< IRSimilarityCandidate *, DenseMap< unsigned, DenseSet< unsigned > > >	llvm::IRSimilarity::CandidateGVNMapping
typedef std::vector< IRSimilarityCandidate >	llvm::IRSimilarity::SimilarityGroup
typedef std::vector< SimilarityGroup >	llvm::IRSimilarity::SimilarityGroupList

Enumerations
enum	llvm::IRSimilarity::InstrType { llvm::IRSimilarity::Legal , llvm::IRSimilarity::Illegal , llvm::IRSimilarity::Invisible }
	This represents what is and is not supported when finding similarity in Instructions. More...

Functions
bool	llvm::IRSimilarity::isClose (const IRInstructionData &A, const IRInstructionData &B)
	Compare one IRInstructionData class to another IRInstructionData class for whether they are performing a the same operation, and can mapped to the same value.
