  50    All hppa opcodes are 32 bits.
  51
  52    The match component is a mask saying which bits must match a
  53    particular opcode in order for an instruction to be an instance
  54    of that opcode.
  55
  56    The args component is a string containing one character
  57    for each operand of the instruction.
  58
  59    Bit positions in this description follow HP usage of lsb = 31,
  60    "at" is lsb of field.
  61
  62    In the args field, the following characters must match exactly:
  63
  64         '+,() '
  65
  66    In the args field, the following characters are unused:
  67
  68         '  "#$%    *+- ./   3      :; =  @'
  69         ' B         L N            [\] _'
  70         '    e gh   lm   qr      yz{|} '
  71
  72    Here are all the characters:
  73
  74         ' !"#$%&'()*+-,./0123456789:;<=>?@'
  75         'ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'
