   All hppa opcodes are 32 bits.

   The match component is a mask saying which bits must match a
   particular opcode in order for an instruction to be an instance
   of that opcode.

   The args component is a string containing one character for each operand of
   the instruction.  Characters used as a prefix allow any second character to
   be used without conflicting with the main operand characters.

   Bit positions in this description follow HP usage of lsb = 31,
   "at" is lsb of field.

   In the args field, the following characters must match exactly:

	'+,() '

   In the args field, the following characters are unused:

	' !"#$%&   *+- ./          :;< > @'
	'            M       U     [\]  '
	'a  d                      {|}~'

   Here are all the characters:

	' !"#$%&'()*+-,./0123456789:;<=>?@'
	'ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'
	'abcdefghijklmnopqrstuvwxyz{|}~'

Kinds of operands:
   x    integer register field at 15.
   b    integer register field at 10.
   t    integer register field at 31.
   y    floating point register field at 31
   5    5 bit immediate at 15.
   s    2 bit space specifier at 17.
   S    3 bit space specifier at 18.
   c    indexed load completer.
   C    short load and store completer.
   Y	Store Bytes Short completer
   V    5 bit immediate value at 31
   i    11 bit immediate value at 31
   j    14 bit immediate value at 31
   k    21 bit immediate value at 31
   n	nullification for branch instructions
   N	nullification for spop and copr instructions
   w    12 bit branch displacement
   W    17 bit branch displacement (PC relative)
   z    17 bit branch displacement (just a number, not an address)

Condition operands all have '?' as the prefix:

   ?f   Floating point compare conditions (encoded as 5 bits at 31)

   ?a	add conditions
   ?A	64 bit add conditions
   ?@   add branch conditions followed by nullify
   ?d	non-negated add branch conditions

   ?y   shift/extract/deposit conditions followed by nullify for conditional
        branches

   ?u   unit conditions
   ?U   64 bit unit conditions

Also these:

        31-p
   P    5 bit bit position at 26
   T    5 bit field length at 31 (encoded as 32-T)

	(for 0xe format FP instructions)
   G    Destination Floating Point Operand Format Completer encoded 2 bits at 18

   s    2 bit space specifier at 17.
   b    register field at 10.
   r	5 bit immediate value at 31 (for the break instruction)
	(very similar to V above, except the value is unsigned instead of
	low_sign_ext)
   R	5 bit immediate value at 15 (for the ssm, rsm, probei instructions)
	(same as r above, except the value is in a different location)
   Q	5 bit immediate value at 10 (a bit position specified in
	the bb instruction. It's the same as r above, except the
        value is in a different location)

And these (PJH) for PA-89 F.P. registers and instructions:

   v    a 't' operand type extended to handle L/R register halves.
   E    a 'b' operand type extended to handle L/R register halves.
   X    an 'x' operand type extended to handle L/R register halves.

   8    5 bit register field at 20 (used in 'fmpyadd' and 'fmpysub')
   9    5 bit register field at 25 (used in 'fmpyadd' and 'fmpysub')
   H    Floating Point Operand Format at 26 for 'fmpyadd' and 'fmpysub'
        (very similar to 'F')
