ARM patch -- extra info about cpsr register

Not at all.  It's not the implementation that's important; it's that the 
information be decoded for the user.  Mapping a hex number to a set of 
mnemonics is something a computer is good and and a human is not.   If 
your version allows the user to set the register mnemonically as well, 
then all the better.

Please keep me posted on your patch.
