Can you use a different name. Register is almost an intptr_t.

 
   // Inlined allocation of an instance of class 'cls', code has no runtime
   // calls. Jump to 'failure' if the instance cannot be allocated here.
   // Allocated instance is returned in 'instance_reg'.
   // Only the tags field of the object is initialized.
   void TryAllocate(const Class& cls,
                    Label* failure,
                    bool near_jump,
                    Register instance_reg,
                    Register temp_reg);
