|
| 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>. */
|
| 208 |
|
| 209 |
|
| 210 |
/* Please note the order of the opcodes in this table is significant.
|
| 211 |
The assembler requires that all instances of the same mnemonic must
|
| 212 |
be consecutive. If they aren't, the assembler might not recognize
|
| 213 |
them, or may indicate an internal error.
|
| 214 |
|
| 215 |
The disassembler should not normally care about the order of the
|
| 216 |
opcodes, but will prefer an earlier alternative if the "match-score"
|
| 217 |
(see cris-dis.c) is computed as equal.
|
| 218 |
|
| 219 |
It should not be significant for proper execution that this table is
|
| 220 |
in alphabetical order, but please follow that convention for an easy
|

overview. */
