Heavily munged by me to:
- reduce table size significantly.
- follow various opcode tables in the Sparc Architecture Manual (V9)
more closely.
- recognise V8 priviliged instructions.
- fit the DDB interface.
- fix many typos.
Todo:
- get a number of FP ops right (unimportant until V9 is here).
- opcode aliases (`mov',`cmp',`set') for simple instructions.
- better template matching; current method is sloppy and is prone to spurious
matches.
