 ===== Register Usage =====
-Registers can be classified as //dedicated//, //volatile// or //nonvolatile//. //Dedicated// are register with a special purpose, such as the stackpointer. //Volatile// means, that this register might be used any time. It does not have to be stored when another method is called. //Nonvolatile// registers must be saved in the prologue of a method before they can be used and after use they must be restored. The number of volatile and nonvolatile registers must be equal for all methods.
 | Register | State | Use |
 | R0 | volatile | method prologue, scratch register |
