/* All CRIS opcodes are 16 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 characters symbolically

     matching the operands of an instruction.  Used for both assembly

     and disassembly.

     Operand-matching characters:

     [ ] , space

        Verbatim.

     A        The string "ACR" (case-insensitive).

     B        Not really an operand.  It causes a "BDAP -size,SP" prefix to be

        output for the PUSH alias-instructions and recognizes a push-

        prefix at disassembly.  This letter isn't recognized for v32.

        Must be followed by a R or P letter.

     !        Non-match pattern, will not match if there's a prefix insn.

     b        Non-matching operand, used for branches with 16-bit

        displacement. Only recognized by the disassembler.

     c        5-bit unsigned immediate in bits <4:0>.

     C        4-bit unsigned immediate in bits <3:0>.

     d  At assembly, optionally (as in put other cases before this one)

        ".d" or ".D" at the start of the operands, followed by one space

        character.  At disassembly, nothing.

     D        General register in bits <15:12> and <3:0>.

     f        List of flags in bits <15:12> and <3:0>.

     i        6-bit signed immediate in bits <5:0>.

     I        6-bit unsigned immediate in bits <5:0>.

     M        Size modifier (B, W or D) for CLEAR instructions.

     m        Size modifier (B, W or D) in bits <5:4>

     N  A 32-bit dword, like in the difference between s and y.

        This has no effect on bits in the opcode.  Can also be expressed

        as "[pc+]" in input.

     n  As N, but PC-relative (to the start of the instruction).

     o        [-128..127] word offset in bits <7:1> and <0>.  Used by 8-bit

        branch instructions.

     O        [-128..127] offset in bits <7:0>.  Also matches a comma and a

        general register after the expression, in bits <15:12>.  Used

        only for the BDAP prefix insn (in v32 the ADDOQ insn; same opcode).

     P        Special register in bits <15:12>.

     p        Indicates that the insn is a prefix insn.  Must be first

        character.

     Q  As O, but don't relax; force an 8-bit offset.

     R        General register in bits <15:12>.

     r        General register in bits <3:0>.

     S        Source operand in bit <10> and a prefix; a 3-operand prefix

        without side-effect.

     s        Source operand in bits <10> and <3:0>, optionally with a

        side-effect prefix, except [pc] (the name, not R15 as in ACR)

        isn't allowed for v32 and higher.

     T  Support register in bits <15:12>.

     u  4-bit (PC-relative) unsigned immediate word offset in bits <3:0>.

     U  Relaxes to either u or n, instruction is assumed LAPCQ or LAPC.

        Not recognized at disassembly.

     x        Register-dot-modifier, for example "r5.w" in bits <15:12> and <5:4>.

     y        Like 's' but do not allow an integer at assembly.

     Y        The difference s-y; only an integer is allowed.

     z        Size modifier (B or W) in bit <4>.  */

/* Please note the order of the opcodes in this table is significant.

   The assembler requires that all instances of the same mnemonic must

   be consecutive.  If they aren't, the assembler might not recognize

   them, or may indicate an internal error.

   The disassembler should not normally care about the order of the

   opcodes, but will prefer an earlier alternative if the "match-score"

   (see cris-dis.c) is computed as equal.

   It should not be significant for proper execution that this table is

   in alphabetical order, but please follow that convention for an easy

   overview.  */
