Bug in documentation, TargetRegisterInfo.h

/// emitProlog/emitEpilog - These methods insert prolog and epilog code
into

  /// the function. The return value is the number of instructions

  /// added to (negative if removed from) the basic block (entry for
prologue).

  ///

  virtual void emitPrologue(MachineFunction &MF) const = 0;

  virtual void emitEpilogue(MachineFunction &MF,

                            MachineBasicBlock &MBB) const = 0;

There is no return type for these functions but the documentation states
that there should be.
