143 /* All CRIS opcodes are 16 bits.
145 - The match component is a mask saying which bits must match a
146 particular opcode in order for an instruction to be an instance
149 - The args component is a string containing characters symbolically
150 matching the operands of an instruction. Used for both assembly
153 Operand-matching characters:
156 A The string "ACR" (case-insensitive).
157 B Not really an operand. It causes a "BDAP -size,SP" prefix to be
158 output for the PUSH alias-instructions and recognizes a push-
159 prefix at disassembly. This letter isn't recognized for v32.
160 Must be followed by a R or P letter.
161 ! Non-match pattern, will not match if there's a prefix insn.
162 b Non-matching operand, used for branches with 16-bit
163 displacement. Only recognized by the disassembler.
164 c 5-bit unsigned immediate in bits <4:0>.
165 C 4-bit unsigned immediate in bits <3:0>.
166 d At assembly, optionally (as in put other cases before this one)
167 ".d" or ".D" at the start of the operands, followed by one space
168 character. At disassembly, nothing.
169 D General register in bits <15:12> and <3:0>.
170 f List of flags in bits <15:12> and <3:0>.
171 i 6-bit signed immediate in bits <5:0>.
172 I 6-bit unsigned immediate in bits <5:0>.
173 M Size modifier (B, W or D) for CLEAR instructions.
174 m Size modifier (B, W or D) in bits <5:4>
175 N A 32-bit dword, like in the difference between s and y.
176 This has no effect on bits in the opcode. Can also be expressed
178 n As N, but PC-relative (to the start of the instruction).
179 o [-128..127] word offset in bits <7:1> and <0>. Used by 8-bit
181 O [-128..127] offset in bits <7:0>. Also matches a comma and a
182 general register after the expression, in bits <15:12>. Used
183 only for the BDAP prefix insn (in v32 the ADDOQ insn; same opcode).
184 P Special register in bits <15:12>.
185 p Indicates that the insn is a prefix insn. Must be first
187 Q As O, but don't relax; force an 8-bit offset.
188 R General register in bits <15:12>.
189 r General register in bits <3:0>.
190 S Source operand in bit <10> and a prefix; a 3-operand prefix
192 s Source operand in bits <10> and <3:0>, optionally with a
193 side-effect prefix, except [pc] (the name, not R15 as in ACR)
194 isn't allowed for v32 and higher.
195 T Support register in bits <15:12>.
196 u 4-bit (PC-relative) unsigned immediate word offset in bits <3:0>.
197 U Relaxes to either u or n, instruction is assumed LAPCQ or LAPC.
198 Not recognized at disassembly.
199 x Register-dot-modifier, for example "r5.w" in bits <15:12> and <5:4>.
200 y Like 's' but do not allow an integer at assembly.
201 Y The difference s-y; only an integer is allowed.
202 z Size modifier (B or W) in bit <4>. */
205 /* Please note the order of the opcodes in this table is significant.
206 The assembler requires that all instances of the same mnemonic must
207 be consecutive. If they aren't, the assembler might not recognize
208 them, or may indicate an internal error.
210 The disassembler should not normally care about the order of the
211 opcodes, but will prefer an earlier alternative if the "match-score"
212 (see cris-dis.c) is computed as equal.
