  54    All hppa opcodes are 32 bits.
  55
  56    The match component is a mask saying which bits must match a
  57    particular opcode in order for an instruction to be an instance
  58    of that opcode.
  59
  60    The args component is a string containing one character
  61    for each operand of the instruction.
  62
  63    Bit positions in this description follow HP usage of lsb = 31,
  64    "at" is lsb of field.
  65
  66    In the args field, the following characters must match exactly:
  67
  68         '+,() '
  69
  70    In the args field, the following characters are unused:
  71
  72         '  "#$%    *+- ./   3      :; =  @'
  73         ' B         L              [\] _'
  74         '    e gh   lm   qr        { } '
  75
  76    Here are all the characters:
  77
  78         ' !"#$%&'()*+-,./0123456789:;<=>?@'
  79         'ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'
