  51    The match component is a mask saying which bits must match a
  52    particular opcode in order for an instruction to be an instance
  53    of that opcode.
  54
  55    The args component is a string containing one character
  56    for each operand of the instruction.
  57
  58    Bit positions in this description follow HP usage of lsb = 31,
  59    "at" is lsb of field.
  60
  61    In the args field, the following characters must match exactly:
  62
  63         '+,() '
  64
  65    In the args field, the following characters are unused:
  66
  67         '  "#$%    *+- ./   3      :; =   '
  68         ' B         L              [\] _'
  69         '    e gh   lm   qr        { } '
  70
  71    Here are all the characters:
  72
  73         ' !"#$%&'()*+-,./0123456789:;<=>?@'
  74         'ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'
