Additional Inherited Members
Protected Member Functions inherited from llvm::ThunkInserter< RetpolineThunkInserter >
void	createThunkFunction (MachineModuleInfo &MMI, StringRef Name, bool Comdat=true, StringRef TargetAttrs="")
	Create an empty thunk function.
void	doInitialization (Module &M)
	Initializes thunk inserter.
const char *	getThunkPrefix ()
	Returns common prefix for thunk function's names.
bool	mayUseThunk (const MachineFunction &MF)
	Checks if MF may use thunks (true - maybe, false - definitely not).
bool	insertThunks (MachineModuleInfo &MMI, MachineFunction &MF, bool ExistingThunks)
	Rewrites the function if necessary, returns the set of thunks added.
void	populateThunk (MachineFunction &MF)
	Populate the thunk function with instructions.
