Classes
struct	llvm::FunctionHashInfo

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

Typedefs
using	llvm::IndexPair = std::pair< unsigned, unsigned >
	The pair of an instruction index and a operand index.
using	llvm::IndexInstrMap = MapVector< unsigned, Instruction * >
	A map from an instruction index to an instruction pointer.
using	llvm::IndexOperandHashMapType = DenseMap< IndexPair, stable_hash >
	A map from an IndexPair to a stable hash.
using	llvm::IgnoreOperandFunc = std::function< bool(const Instruction *, unsigned)>
	A function that takes an instruction and an operand index and returns true if the operand should be ignored in the function hash computation.

Functions
stable_hash	llvm::StructuralHash (const Function &F, bool DetailedHash=false)
	Returns a hash of the function F.
stable_hash	llvm::StructuralHash (const GlobalVariable &G)
	Returns a hash of the global variable G.
stable_hash	llvm::StructuralHash (const Module &M, bool DetailedHash=false)
	Returns a hash of the module M by hashing all functions and global variables contained within.
FunctionHashInfo	llvm::StructuralHashWithDifferences (const Function &F, IgnoreOperandFunc IgnoreOp)
	Computes a structural hash of a given function, considering the structure and content of the function's instructions while allowing for selective ignoring of certain operands based on custom criteria.
