GDB/MI Data Manipulation
33 
========================
34 
 
35 
   This section describes the GDB/MI commands that manipulate data:
36 
examine memory and registers, evaluate expressions, etc.
37 
 
38 
The `-data-disassemble' Command
39 
-------------------------------
40 
 
41 
Synopsis
42 
........
43 
 
44 
      -data-disassemble
45 
         [ -s START-ADDR -e END-ADDR ]
46 
       | [ -f FILENAME -l LINENUM [ -n LINES ] ]
47 
       -- MODE
48 
 
49 
Where:
50 
 
51 
`START-ADDR'
52 
     is the beginning address (or `$pc')
53 
 
54 
`END-ADDR'
55 
     is the end address
56 
 
57 
`FILENAME'
58 
     is the name of the file to disassemble
59 
 
60 
`LINENUM'
61 
     is the line number to disassemble around
62 
 
63 
`LINES'
64 
     is the the number of disassembly lines to be produced.  If it is
65 
     -1, the whole function will be disassembled, in case no END-ADDR is
66 
     specified.  If END-ADDR is specified as a non-zero value, and
67 
     LINES is lower than the number of disassembly lines between
68 
     START-ADDR and END-ADDR, only LINES lines are displayed; if LINES
69 
     is higher than the number of lines between START-ADDR and
70 
     END-ADDR, only the lines up to END-ADDR are displayed.
71 
 
72 
`MODE'
73 
     is either 0 (meaning only disassembly) or 1 (meaning mixed source
74 
     and disassembly).
75 
 
76 
Result
77 
......
78 
 
79 
   The output for each instruction is composed of four fields:
80 
 
81 
   * Address
82 
 
83 
   * Func-name
84 
 
85 
   * Offset
86 
 
87 
   * Instruction
88 
 
89 
   Note that whatever included in the instruction field, is not
90 
manipulated directely by GDB/MI, i.e. it is not possible to adjust its
91 
format.
92 
 
93 
GDB Command
94 
...........
95 
 
96 
   There's no direct mapping from this command to the CLI.
97 
 
98

The `-data-evaluate-expression' Command
167 
---------------------------------------
168 
 
169 
Synopsis
170 
........
171 
 
172 
      -data-evaluate-expression EXPR
173 
 
174 
   Evaluate EXPR as an expression.  The expression could contain an
175 
inferior function call.  The function call will execute synchronously.
176 
If the expression contains spaces, it must be enclosed in double quotes.
177 
 
178 
GDB Command
179 
...........
180 
 
181 
   The corresponding GDB commands are `print', `output', and `call'.
182 
In `gdbtk' only, there's a corresponding `gdb_eval' command.
183 
 
184 
Example
185 
.......
186 
 
187 
   In the following example, the numbers that precede the commands are
188 
the "tokens" described in *Note GDB/MI Command Syntax: GDB/MI Command
189 
Syntax.  Notice how GDB/MI returns the same tokens in its output.

207 
Synopsis
208 
........
209 
 
210 
      -data-list-changed-registers
211 
 
212 
   Display a list of the registers that have changed.
213 
 
214 
GDB Command
215 
...........
216 
 
217 
   GDB doesn't have a direct analog for this command; `gdbtk' has the
218 
corresponding command `gdb_changed_register_list'.
219 
 
220 
Example
221 
.......
222 
 
223 
   On a PPC MBX board:
224 
 
225 
     (gdb)
226 
     -exec-continue
227 
     ^running
228 
 
229 
     (gdb)
230 
     *stopped,reason="breakpoint-hit",bkptno="1",frame={func="main",
231 
     args=[],file="try.c",line="5"}
232 
     (gdb)
233 
     -data-list-changed-registers
234 
     ^done,changed-registers=["0","1","2","4","5","6","7","8","9",
235 
     "10","11","13","14","15","16","17","18","19","20","21","22","23",
236 
     "24","25","26","27","28","30","31","64","65","66","67","69"]
237

239 
The `-data-list-register-names' Command
240 
---------------------------------------
241 
 
242 
Synopsis
243 
........
244 
 
245 
      -data-list-register-names [ ( REGNO )+ ]
246 
 
247 
   Show a list of register names for the current target.  If no
248 
arguments are given, it shows a list of the names of all the registers.
249 
If integer numbers are given as arguments, it will print a list of the
250 
names of the registers corresponding to the arguments.  To ensure
251 
consistency between a register name and its number, the output list may
252 
include empty register names.
253 
 
254 
GDB Command
255 
...........
256 
 
257 
   GDB does not have a command which corresponds to
258 
`-data-list-register-names'.  In `gdbtk' there is a corresponding
259 
command `gdb_regnames'.
260 
 
261 
Example
262 
.......
263 
 
264 
   For the PPC MBX board:
265 
     (gdb)
266 
     -data-list-register-names

282 
Synopsis
283 
........
284 
 
285 
      -data-list-register-values FMT [ ( REGNO )*]
286 
 
287 
   Display the registers' contents.  FMT is the format according to
288 
which the registers' contents are to be returned, followed by an
289 
optional list of numbers specifying the registers to display.  A
290 
missing list of numbers indicates that the contents of all the
291 
registers must be returned.
292 
 
293 
   Allowed formats for FMT are:
294 
 
295 
`x'
296 
     Hexadecimal
297 
 
298 
`o'
299 
     Octal

     the same as for GDB's `print' command (*note Output formats:
389 
     Output Formats.).
390 
 
391 
`WORD-SIZE'
392 
     The size of each memory word in bytes.
393 
 
394 
`NR-ROWS'
395 
     The number of rows in the output table.
396 
 
397 
`NR-COLS'
398 
     The number of columns in the output table.
399 
 
400 
`ASCHAR'
401 
     If present, indicates that each row should include an ASCII dump.
402 
     The value of ASCHAR is used as a padding character when a byte is
403 
     not a member of the printable ASCII character set (printable ASCII
404 
     characters are those whose code is between 32 and 126,
405 
     inclusively).
406 
 
407 
`BYTE-OFFSET'
408 
     An offset to add to the ADDRESS before fetching memory.
409 
 
410 
   This command displays memory contents as a table of NR-ROWS by
411 
NR-COLS words, each word being WORD-SIZE bytes.  In total, `NR-ROWS *
412 
NR-COLS * WORD-SIZE' bytes are read (returned as `total-bytes').
413 
Should less than the requested number of bytes be returned by the
414 
target, the missing words are identified using `N/A'.  The number of
415 
bytes read from the target is returned in `nr-bytes' and the starting
416 
address used to read memory in `addr'.
417 
 
418 
   The address of the next/previous row or page is available in
419 
`next-row' and `prev-row', `next-page' and `prev-page'.

Program termination
674 
...................
675 
 
676 
   As a result of execution, the inferior program can run to
677 
completion, if it doesn't encounter any breakpoints.  In this case the
678 
output will include an exit code, if the program has exited
679 
exceptionally.
680 
 
681 
Examples
682 
........
683 
 
684 
Program exited normally:
685 
 
686 
     (gdb)
687 
     -exec-run
688 
     ^running
689 
     (gdb)
690 
     x = 55
691 
     *stopped,reason="exited-normally"
692 
     (gdb)

694 
Program exited exceptionally:
695 
 
696 
     (gdb)
697 
     -exec-run

     *stopped,reason="exited",exit-code="01"
702 
     (gdb)
703 
 
704 
   Another way the program can terminate is if it receives a signal
705 
such as `SIGINT'.  In this case, GDB/MI displays this:
706 
 
707 
     (gdb)

1456 
 
1457 
      -stack-list-arguments SHOW-VALUES
1458 
         [ LOW-FRAME HIGH-FRAME ]
1459 
 
1460 
   Display a list of the arguments for the frames between LOW-FRAME and
1461 
HIGH-FRAME (inclusive).  If LOW-FRAME and HIGH-FRAME are not provided,
1462 
list the arguments for the whole call stack.
1463 
 
1464 
   The SHOW-VALUES argument must have a value of 0 or 1.  A value of 0
1465 
means that only the names of the arguments are listed, a value of 1
1466 
means that both names and values of the arguments are printed.

   GDB does not have an equivalent command.  `gdbtk' has a
1472 
`gdb_get_args' command which partially overlaps with the functionality
1473 
of `-stack-list-arguments'.

      -stack-list-frames [ LOW-FRAME HIGH-FRAME ]
1533 
 
1534 
   List the frames currently on the stack.  For each frame it displays
1535 
the following info:
1536 
 
1537 
`LEVEL'
1538 
     The frame number, 0 being the topmost frame, i.e. the innermost
1539 
     function.
1540 
 
1541 
`ADDR'
1542 
     The `$pc' value for that frame.
1543 
 
1544 
`FUNC'
1545 
     Function name.
1546 
 
1547 
`FILE'
1548 
     File name of the source file where the function lives.
1549 
 
1550 
`LINE'
1551 
     Line number corresponding to the `$pc'.
1552 
 
1553 
   If invoked without arguments, this command prints a backtrace for the
1554 
whole stack.  If given two integer arguments, it shows the frames whose
1555 
levels are between the two arguments (inclusive).  If the two arguments
1556 
are equal, it shows the single frame at the corresponding level.
