Changes much prior to version 2.0 are lost in the mists of time.
Richard Stallman, assisted at various times by Peter TerMaat, Chris
Hanson, and Richard Mlynarik, handled releases through 2.8.
-Michael Tiemann is the author of most of the @sc{gnu} C++ support in GDB,
-with significant additional contributions from Per Bothner. James
-Clark wrote the @sc{gnu} C++ demangler. Early work on C++ was by Peter
-TerMaat (who also did much general update work leading to release 3.0).

@table @code
@item -symbols @var{file}

Read symbol table from file @var{file}.
@item -exec @var{file}
@itemx -e @var{file}
+@cindex @code{--exec}
+@cindex @code{-e}
Use file @var{file} as the executable file to execute when appropriate,
and for examining pure data in conjunction with a core dump.
@item -se @var{file}

@item -core @var{file}

@item -c @var{number}
@item -command @var{file}
@itemx -x @var{file}

+@cindex @code{-x}
Execute @value{GDBN} commands from file @var{file}. @xref{Command

@item -directory @var{directory}

+@cindex @code{-d}
Add @var{directory} to the path to search for source files.
@item -m
@itemx -mapped
+@cindex @code{--mapped}
+@cindex @code{-m}
@emph{Warning: this option depends on operating system facilities that are not
supported on all systems.}@*
If memory-mapped files are available on your system through the @code{mmap}
system call, you can use this option
to have @value{GDBN} write the symbols from your
program into a reusable file in the current directory. If the program you are debugging is
-called @file{/tmp/fred}, the mapped symbol file is @file{./fred.syms}.
+called @file{/tmp/fred}, the mapped symbol file is @file{/tmp/fred.syms}.
Future @value{GDBN} debugging sessions notice the presence of this file,
and can quickly map in symbol information from it, rather than reading
the symbol table from the executable program.
@item -r
@itemx -readnow
+@cindex @code{--readnow}
+@cindex @code{-r}
Read each symbol file's entire symbol table immediately, rather than
the default, which is to read it incrementally as it is needed.
This makes startup slower, but makes future operations faster.
@table @code
@item -nx
@itemx -n
+@cindex @code{--nx}
+@cindex @code{-n}
Do not execute commands found in any initialization files (normally
called @file{.gdbinit}, or @file{gdb.ini} on PCs). Normally,
@value{GDBN} executes the commands in these files after all the command
files}.
@item -quiet
+@itemx -silent
@itemx -q
+@cindex @code{--quiet}
+@cindex @code{--silent}
+@cindex @code{-q}
``Quiet''. Do not print the introductory and copyright messages. These
messages are also suppressed in batch mode.
@item -batch
+@cindex @code{--batch}
Run in batch mode. Exit with status @code{0} after processing all the
command files specified with @samp{-x} (and all commands from
initialization files, if not inhibited with @samp{-n}). Exit with
@item -nowindows
@itemx -nw
+@cindex @code{--nowindows}
+@cindex @code{-nw}
``No windows''. If @value{GDBN} comes with a graphical user interface

+(GUI) built in, then this option tells @value{GDBN} to only use the command-line
interface. If no GUI is available, this option has no effect.
@item -windows
@itemx -w
+@cindex @code{--windows}
+@cindex @code{-w}
If @value{GDBN} includes a GUI, then this option requires it to be
used if possible.
@item -cd @var{directory}
+@cindex @code{--cd}
Run @value{GDBN} using @var{directory} as its working directory,
instead of the current directory.
@item -fullname
@itemx -f
+@cindex @code{--fullname}
+@cindex @code{-f}
@sc{gnu} Emacs sets this option when it runs @value{GDBN} as a
subprocess. It tells @value{GDBN} to output the full file name and line
number in a standard, recognizable fashion each time a stack frame is
@samp{\032} characters as a signal to display the source code for the
frame.
+@item -epoch
+@cindex @code{--epoch}
+The Epoch Emacs-@value{GDBN} interface sets this option when it runs
+@value{GDBN} as a subprocess. It tells @value{GDBN} to modify its print
+routines so as to allow Epoch to display values of expressions in a
+separate window.
+
+@item -annotate @var{level}
+@cindex @code{--annotate}
+This option sets the @dfn{annotation level} inside @value{GDBN}. Its
+effect is identical to using @samp{set annotate @var{level}}
+(@pxref{Annotations}).
+Annotation level controls how much information does @value{GDBN} print
+together with its prompt, values of expressions, source lines, and other
+types of output. Level 0 is the normal, level 1 is for use when
+@value{GDBN} is run as a subprocess of @sc{gnu} Emacs, level 2 is the
+maximum annotation suitable for programs that control @value{GDBN}.
+
+@item -async
+@cindex @code{--async}
+Use the asynchronous event loop for the command-line interface.
+@value{GDBN} processes all events, such as user keyboard input, via a
+special event loop. This allows @value{GDBN} to accept and process user
+commands in parallel with the debugged process being
+run@footnote{@value{GDBN} built with @sc{djgpp} tools for
+MS-DOS/MS-Windows supports this mode of operation, but the event loop is
+suspended when the debuggee runs.}, so you don't need to wait for
+control to return to @value{GDBN} before you type the next command.
+(@emph{Note:} as of version 5.0, the target side of the asynchronous
+operation is not yet in place, so @samp{-async} does not work fully
+yet.)
+@c FIXME: when the target side of the event loop is done, the above NOTE
+@c should be removed.
+
+When the standard input is connected to a terminal device, @value{GDBN}
+uses the asynchronous event loop by default, unless disabled by the
+@samp{-noasync} option.
+
+@item -noasync
+@cindex @code{--noasync}
+Disable the asynchronous event loop for the command-line interface.
+
@item -baud @var{bps}
@itemx -b @var{bps}
+@cindex @code{--baud}
+@cindex @code{-b}
Set the line speed (baud rate or bits per second) of any serial
interface used by @value{GDBN} for remote debugging.
@item -tty @var{device}
+@itemx -t @var{device}
+@cindex @code{--tty}
+@cindex @code{-t}
Run using @var{device} for your program's standard input and output.
@c FIXME: kingdon thinks there is more to -tty. Investigate.
@c resolve the situation of these eventually
@c @item -tui
+@c @cindex @code{--tui}
@c Use a Terminal User Interface. For information, use your Web browser to
@c read the file @file{TUI.html}, which is usually installed in the
@c directory @code{/opt/langtools/wdb/doc} on HP-UX systems. Do not use
@c @value{GDBN} under @sc{gnu} Emacs}).
@c @item -xdb
+@c @cindex @code{--xdb}
@c Run in XDB compatibility mode, allowing the use of certain XDB commands.
@c For information, see the file @file{xdb_trans.html}, which is usually
@c installed in the directory @code{/opt/langtools/wdb/doc} on HP-UX
@c systems.
+@item -interpreter @var{interp}
+@cindex @code{--interpreter}
+Use the interpreter @var{interp} for interface with the controlling
+program or device. This option is meant to be set by programs which
+communicate with @value{GDBN} using it as a back end. For example,
+@samp{--interpreter=mi} causes @value{GDBN} to use the @dfn{gdbmi
+interface}.
+@c FIXME: There should be an @xref here to the GDB/MI docs, but
+@c gdbmi.texi doesn't have a single node to reference!
+
+@item -write
+@cindex @code{--write}
+Open the executable and core files for both reading and writing. This
+is equivalent to the @samp{set write on} command inside @value{GDBN}
+(@pxref{Patching}).
+
+@item -statistics
+@cindex @code{--statistics}
+This option causes @value{GDBN} to print statistics about time and
+memory usage after it completes each command and returns to the prompt.
+
+@item -version
+@cindex @code{--version}
+This option causes @value{GDBN} to print its version number and
+no-warranty blurb, and exit.

+@code{@value{GDBN}} has another special command to set the communications
speed: @samp{speed @var{bps}}. This command also is only used from Unix
hosts; on DOS hosts, set the line speed as usual from outside @value{GDBN} with
the DOS @code{mode} command (for instance,
@kindex target hms@r{, and serial protocol}
Now that serial communications are set up, and the development board is
connected, you can start up @value{GDBN}. Call @code{@value{GDBP}} with
-the name of your program as the argument. @code{@value{GDBP}} prompts
+the name of your program as the argument. @code{@value{GDBN}} prompts
you, as usual, with the prompt @samp{(@value{GDBP})}. Use two special
commands to begin your debugging session: @samp{target hms} to specify
cross-debugging to the Hitachi board, and the @code{load} command to
@cindex floating point, MIPS remote
If your target board does not support the MIPS floating point
coprocessor, you should use the command @samp{set mipsfpu none} (if you

file). This tells @value{GDBN} how to find the return value of
functions which return floating point values. It also allows
@value{GDBN} to avoid saving the floating point registers when calling
each value is printed in its own window.
