   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.

   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:

	'  "#$%    *+- ./          :;    '
	'                          [\]  '
	'                          { } '

   Here are all the characters:

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

Kinds of operands:

	low_sign_ext)

	(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)
   |	shift/extract/deposit conditions when used in a conditional branch
