  - Calling conventions, i.e., caller-saves versus callee-saves
      registers, parameter-transfer registers and registers used for
      return address and stack/frame pointer.


  - Special-purpose registers, such as multiplication using specific
      registers for arguments and results.


  - Register types such as address/integer/FP registers.
