   All hppa opcodes are 32 bits.

   The match component is a mask saying which bits must match a

   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:

        '  "         -  /   34 678 :;    '

        '@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'
        '`abcdefghijklmnopqrstuvwxyz{|}~ '

/* The order of the opcodes in this table is significant:

   * The assembler requires that all instances of the same mnemonic be
     consecutive.  If they aren't, the assembler will bomb at runtime.

   * Immediate fields use pa_get_absolute_expression to parse the
     string.  It will generate a "bad expression" error if passed
     a register name.  Thus, register index variants of an opcode
     need to precede immediate variants.

   * The disassembler does not care about the order of the opcodes
     except in cases where implicit addressing is used.

   Here are the rules for ordering the opcodes of a mnemonic:

   1) Opcodes with FLAG_STRICT should precede opcodes without
      FLAG_STRICT.

   2) Opcodes with FLAG_STRICT should be ordered as follows:
      register index opcodes, short immediate opcodes, and finally
      long immediate opcodes.  When both pa10 and pa11 variants
      of the same opcode are available, the pa10 opcode should
      come first for correct architectural promotion.

   3) When implicit addressing is available for an opcode, the
      implicit opcode should precede the explicit opcode.

   4) Opcodes without FLAG_STRICT should be ordered as follows:
      register index opcodes, long immediate opcodes, and finally
      short immediate opcodes.  */
