| 149 | + | |
| 150 | + - The match component is a mask saying which bits must match a | |
| 151 | + particular opcode in order for an instruction to be an instance | |
| 152 | + of that opcode. | |
| 153 | + | |
| 154 | + - The args component is a string containing characters symbolically | |
| 155 | + matching the operands of an instruction. Used for both assembly | |
| 156 | + and disassembly. | |
| 157 | + | |
| 158 | + Operand-matching characters: | |
| 159 | + [ ] , space | |
| 160 | + Verbatim. | |
| 161 | + A The string "ACR" (case-insensitive). | |
| 162 | + B Not really an operand. It causes a "BDAP -size,SP" prefix to be | |
| 163 | + output for the PUSH alias-instructions and recognizes a push- | |
| 164 | + prefix at disassembly. This letter isn't recognized for v32. | |
| 165 | + Must be followed by a R or P letter. | |
| 166 | + ! Non-match pattern, will not match if there's a prefix insn. | |
| 167 | + b Non-matching operand, used for branches with 16-bit | |
| 168 | + displacement. Only recognized by the disassembler. | |
| 169 | + c 5-bit unsigned immediate in bits <4:0>. | |
| 170 | + C 4-bit unsigned immediate in bits <3:0>. | |
| 171 | + d At assembly, optionally (as in put other cases before this one) | |
| 172 | + ".d" or ".D" at the start of the operands, followed by one space | |
| 173 | + character. At disassembly, nothing. | |
| 174 | + D General register in bits <15:12> and <3:0>. | |
| 175 | + f List of flags in bits <15:12> and <3:0>. | |
| 176 | + i 6-bit signed immediate in bits <5:0>. | |
| 177 | + I 6-bit unsigned immediate in bits <5:0>. | |
| 178 | + M Size modifier (B, W or D) for CLEAR instructions. | |
| 179 | + m Size modifier (B, W or D) in bits <5:4> | |
| 180 | + N A 32-bit dword, like in the difference between s and y. | |
| 181 | + This has no effect on bits in the opcode. Can also be expressed | |
| 182 | + as "[pc+]" in input. | |
| 183 | + n As N, but PC-relative (to the start of the instruction). | |
| 184 | + o [-128..127] word offset in bits <7:1> and <0>. Used by 8-bit | |
| 185 | + branch instructions. | |
| 186 | + O [-128..127] offset in bits <7:0>. Also matches a comma and a | |
| 187 | + general register after the expression, in bits <15:12>. Used | |
| 188 | + only for the BDAP prefix insn (in v32 the ADDOQ insn; same opcode). | |
| 189 | + P Special register in bits <15:12>. | |
| 190 | + p Indicates that the insn is a prefix insn. Must be first | |
| 191 | + character. | |
| 192 | + Q As O, but don't relax; force an 8-bit offset. | |
| 193 | + R General register in bits <15:12>. | |
| 194 | + r General register in bits <3:0>. | |
| 195 | + S Source operand in bit <10> and a prefix; a 3-operand prefix | |
| 196 | + without side-effect. | |
| 197 | + s Source operand in bits <10> and <3:0>, optionally with a | |
| 198 | + side-effect prefix, except [pc] (the name, not R15 as in ACR) | |
| 199 | + isn't allowed for v32 and higher. | |
| 200 | + T Support register in bits <15:12>. | |
| 201 | + u 4-bit (PC-relative) unsigned immediate word offset in bits <3:0>. | |
| 202 | + U Relaxes to either u or n, instruction is assumed LAPCQ or LAPC. | |
| 203 | + Not recognized at disassembly. | |
| 204 | + x Register-dot-modifier, for example "r5.w" in bits <15:12> and <5:4>. | |
| 205 | + y Like 's' but do not allow an integer at assembly. | |
| 206 | + Y The difference s-y; only an integer is allowed. | |
| 207 | + z Size modifier (B or W) in bit <4>. */ | |

| 213 | + them, or may indicate an internal error. | |
| 214 | + | |
