GDB/MI Program control
======================
Program termination
...................
As a result of execution, the inferior program can run to
completion, if it doesn't encouter any breakpoints. In this case the
ouput will include an exit code, if the program has exited
exceptionally.
Examples:
.........
Program exited normally:
(gdb)
-exec-run
^running
(gdb)
x = 55
*stopped,reason="exited-normally"
(gdb)
Program exited exceptionally:
(gdb)
-exec-run
^running
(gdb)
x = 55
*stopped,reason="exited",exit-code="01"
(gdb)
Another way the program can terminate is if it receives a signal
such as `SIGINT'. In this case, GDB/MI displays this:
(gdb)
*stopped,reason="exited-signalled",signal-name="SIGINT",
signal-meaning="Interrupt"
The `-exec-abort' Command
-------------------------
Synopsis
........
-exec-abort
Kill the inferior running program.
GDB Command
...........
The corresponding GDB command is `kill'.
Example

N.A.
The `-exec-arguments' Command
-----------------------------
Synopsis
........
-exec-arguments ARGS
Set the inferior program arguments, to be used in the next
`-exec-run'.

...........
The corresponding GDB command is `set args'.
Example
.......

The `-exec-continue' Command
----------------------------
Synopsis
........
-exec-continue
Asynchronous command. Resumes the execution of the inferior program
until a breakpoint is encountered, or until the inferior exits.
GDB Command
...........
The corresponding GDB corresponding is `continue'.
Example
.......
-exec-continue
^running
(gdb)
@Hello world
*stopped,reason="breakpoint-hit",bkptno="2",frame={func="foo",args={},
file="hello.c",line="13"}
(gdb)
The `-exec-finish' Command
--------------------------
Synopsis
........

until the current function is exited. Displays the results returned by
the function.

...........
The corresponding GDB command is `finish'.
Example
.......
Function returning `void'.
-exec-finish
^running
(gdb)
@hello from foo
*stopped,reason="function-finished",frame={func="main",args={},
file="hello.c",line="7"}
(gdb)
Function returning other than `void'. The name of the internal GDB
variable storing the result is printed, together with the value itself.
-exec-finish
^running
(gdb)
*stopped,reason="function-finished",frame={addr="0x000107b0",func="foo",
args={{name="a",value="1"},{name="b",value="9"}},

(gdb)
The `-exec-interrupt' Command
-----------------------------
Synopsis
........
-exec-interrupt
Asynchronous command. Interrupts the background execution of the
target. Note how the token associated with the stop message is the one
for the execution command that has been interrupted. The token for the
interrupt itself only appears in the '^done' output. If the user is
trying to interrupt a non-running program, an error message will be
printed.

(gdb)
The `-exec-run' Command
-----------------------
Synopsis
........
-exec-run
Asynchronous command. Starts execution of the inferior from the
beginning. The inferior executes until either a breakpoint is
encountered or the program exits.
GDB Command
...........
The corresponding GDB command is `run'.
Example
.......
(gdb)
-break-insert main
^done,bkpt={number="1",addr="0x0001072c",file="recursive2.c",line="4"}

(gdb)
The `-exec-step-instruction' Command
------------------------------------
Synopsis
........
-exec-step-instruction
Asynchronous command. Resumes the inferior which executes one
machine instruction. The output, once GDB has stopped, will vary
depending on whether we have stopped in the middle of a source line or
not. In the former case, the address at which the program stopped will
be printed as well.
GDB Command
...........
The corresponding GDB command is `stepi'.
Example
.......
(gdb)

The `-exec-until' Command
-------------------------
Synopsis
........
-exec-until [ LOCATION ]
Asynchronous command. Executes the inferior until the LOCATION
specified in the argument is reached. If there is no argument, the
inferior executes until a source line greater than the current one is
reached. The reason for stopping in this case will be
"location-reached".
GDB Command
...........
The corresponding GDB command is `until'.
Example
.......
(gdb)
-exec-until recursive2.c:6
^running
(gdb)
x = 55

file="recursive2.c",line="6"}
(gdb)
The `-file-exec-and-symbols' Command
------------------------------------
Synopsis
........
-file-exec-and-symbols FILE
Specify the executable file to be debugged. This file is the one
from which the symbol table is also read. If no file is specified, the
command clears the executable and symbol information. If breakpoints
are set when using this command with no arguments, gdb will produce
error messages. Otherwise, no output is produced, except a completion
notification.
GDB Command
...........
The corresponding GDB command is `file'.
Example
.......
(gdb)
-file-exec-and-symbols /kwikemart/marge/ezannoni/TRUNK/mbx/hello.mbx
^done
(gdb)
The `-file-exec-file' Command
-----------------------------
Synopsis
........
-file-exec-file FILE
Specify the executable file to be debugged. Unlike
`-file-exec-and-symbols', the symbol table is _not_ read from this
file. If used without argument, GDB clears the information about the
executable file. No output is produced, except a completion
notification.
GDB Command
...........
The corresponding GDB command is `exec-file'.
Example
.......
(gdb)
-file-exec-file /kwikemart/marge/ezannoni/TRUNK/mbx/hello.mbx
^done
(gdb)
The `-file-list-exec-sections' Command
--------------------------------------
Synopsis
........
-file-list-exec-sections
List the sections of the current executable file.
GDB Command
...........
The GDB command `info file' shows, among the rest, the same
information as this command. `gdbtk' has a corresponding command
`gdb_load_info'.
Example
.......
N.A.
The `-file-list-exec-source-files' Command
------------------------------------------
Synopsis
........
-file-list-exec-source-files
List the source files for the current executable.
GDB Command
...........
There's no GDB command which directly corresponds to this one.
`gdbtk' has an analogous command `gdb_listfiles'.
Example
.......
N.A.
The `-file-list-shared-libraries' Command
-----------------------------------------
Synopsis
........
-file-list-shared-libraries
List the shared libraries in the program.

The corresponding GDB command is `info file' (part of it).
Example
.......
N.A.
The `-file-symbol-file' Command
-------------------------------
Synopsis
........
-file-symbol-file FILE
Read symbol table info from the specified FILE argument. When used
without arguments, clears GDB's symbol table info. No output is
produced, except for a completion notification.
GDB Command
