+ /* 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:
+ 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. 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 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>
+ 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. Used only for the BDAP
+ prefix insn.
+ P Special register in bits <15:12>.
+ p Indicates that the insn is a prefix insn. Must be first
+ character.
+ 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.
+ 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.
+ 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 and 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. */
