This file defines the BumpPtrAllocator interface.

This file defines DenseMapInfo traits for DenseMap<std::variant<Ts...>>.

This file implements a map that provides insertion order iteration.

This file implements a set that has insertion order iteration characteristics.

This file defines the SmallVector class.

ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...

Lightweight error class with error context and mandatory checking.

This class implements a map that also provides access to all stored values in a deterministic order.

typename VectorType::value_type value_type

A vector that has set insertion semantics.

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

StringRef - Represent a constant reference to a string, i.e.

Saves strings in the provided stable storage and returns a StringRef with a stable character pointer.

LLVM_ABI Error addKnownSymbolWithoutSamples(SymbolHandleRef SymbolID)

Add a symbol that's seen in the profiled binary without samples.

ArrayRef< StringToIndexMap::value_type > getStrToIndexMapRef() const

The following methods return array reference for various internal data structures.

Definition DataAccessProf.h:174

LLVM_ABI Error serialize(ProfOStream &OS) const

Serialize profile data to the output stream.

LLVM_ABI std::optional< DataAccessProfRecord > getProfileRecord(const SymbolHandleRef SymID) const

Returns a profile record for SymbolID, or std::nullopt if there isn't a record.

ArrayRef< MapVector< SymbolHandleRef, internal::DataAccessProfRecordRef >::value_type > getRecords() const

Definition DataAccessProf.h:179

LLVM_ABI Error deserialize(const unsigned char *&Ptr)

Deserialize this class from the given buffer.

ArrayRef< StringRef > getKnownColdSymbols() const

Definition DataAccessProf.h:182

LLVM_ABI bool isKnownColdSymbol(const SymbolHandleRef SymID) const

Returns true if SymID is seen in profiled binaries and cold.

bool empty() const

Definition DataAccessProf.h:188

LLVM_ABI Error setDataAccessProfile(SymbolHandleRef SymbolID, uint64_t AccessCount)

Methods to set symbolized data access profile.

This is an optimization pass for GlobalISel generic memory operations.
