/* 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.  */
