Public Member Functions
DataAccessProfData ()
LLVM_ABI Error serialize (ProfOStream &OS) const
Serialize profile data to the output stream.
LLVM_ABI Error deserialize (const unsigned char *&Ptr)
Deserialize this class from the given buffer.
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.
LLVM_ABI bool isKnownColdSymbol (const SymbolHandleRef SymID) const
Returns true if SymID is seen in profiled binaries and cold.
LLVM_ABI Error setDataAccessProfile (SymbolHandleRef SymbolID, uint64_t AccessCount)
Methods to set symbolized data access profile.
LLVM_ABI Error setDataAccessProfile (SymbolHandleRef SymbolID, uint64_t AccessCount, ArrayRef< SourceLocation > Locations)
Similar to the method above, for records with Locations representing the filename:line where this symbol shows up.
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.
