-@node Reverse Debugging
-@subsubsection Reverse Debugging
-
- The GDB tool bar shares many buttons with the other GUD debuggers
-for tasks like stepping and printing expressions. It also has a
-further set of buttons that allow reverse debugging (@pxref{Process
-Record and Replay, , ,gdb, The GNU debugger}). This is useful when it
-takes a long time to reproduce the conditions where your program fails
-or for transient problems, like race conditions in multi-threaded
-programs, where a failure might otherwise be hard to reproduce.
-
-To use reverse debugging, set a breakpoint slightly before the
-location of interest and run your program to that point. Enable
-process recording by clicking on the record button. At this point, a
-new set of buttons appear. These buttons allow program execution in
-the reverse direction. Run your program over the code where the
-problem occurs, and then use the new set of buttons to retrace your
-steps, examine values, and analyze the problem. When analysis is
-complete, turn off process recording by clicking on the record button
-again.
+@node Multithreaded Debugging
+@subsubsection Stopping and Starting Multi-threaded Programs
+@cindex Multithreaded debugging in GDB
+
+@subsubheading All-stop Debugging
+
+In all-stop mode, whenever your program stops, @emph{all} threads of
+execution stop. Likewise, whenever you restart the program, all
+threads start executing. @xref{All-Stop Mode, , All-Stop Mode, gdb,
+The GNU debugger}. You can enable this behaviour in Emacs by setting
+@code{gdb-non-stop-setting} to @code{nil} before starting a debugging
+session.
+
+@subsubheading Non-stop Debugging
+@cindex Non-stop debugging in GDB
+
+For some multi-threaded targets, GDB supports a further mode of
+operation in which you can examine stopped program threads in the
+debugger while other threads continue to execute freely.
+@xref{Non-Stop Mode, , Non-Stop Mode, gdb, The GNU debugger}.
+This is referred to as @dfn{non-stop} mode.
+
+Versions of GDB prior to 7.0 do not support non-stop mode and it does
+not work on all targets. In such cases, Emacs uses all-stop mode
+regardless of the value of @code{gdb-non-stop-setting}.
+
+@vindex gdb-non-stop-setting
+If the variable @code{gdb-non-stop-setting} is non-@code{nil} (the
+default value), Emacs tries to start GDB in non-stop mode. Note that
+GDB debugging session needs to be restarted for change of this setting
+to take effect.
+
+@vindex gdb-switch-when-another-stopped
+When a thread stops in non-stop mode, Emacs automatically switches to
+that thread. It may be undesirable to allow switching of current
+thread when some other stopped thread is already selected. Set
+@code{gdb-switch-when-another-stopped} to @code{nil} to prevent this.
+
+@vindex gdb-switch-reasons
+Emacs can decide whether or not to switch to the stopped thread
+depending on the reason which caused the stop. Customize
+@code{gdb-switch-reasons} to select stop reasons which make Emacs
+switch thread.
+
+@vindex gdb-stopped-hooks
+The variable @code{gdb-stopped-hooks} allows you to execute your
+functions whenever some thread stops.
+
+ In non-stop mode, you can switch between different modes for GUD
+execution control commands.
+
+@vindex gdb-gud-control-all-threads
+@table @dfn
+@item Non-stop/A
+
+When @code{gdb-gud-control-all-threads} is @code{t} (the default
+value), interruption and continuation commands apply to all threads,
+so you can halt or continue all your threads with one command using
+@code{gud-stop-subjob} and @code{gud-cont}, respectively. The
+@samp{Go} button is shown on the toolbar when at least one thread is
+stopped, whereas @samp{Stop} button is shown when at least one thread
+is running.
+
+@item Non-stop/T
+
+When @code{gdb-gud-control-all-threads} is @code{nil}, only the
+current thread is stopped/continued. @samp{Go} and @samp{Stop}
+buttons on the GUD toolbar are shown depending on the state of current
+thread.
+@end table
+
+You can change the current value of @code{gdb-gud-control-all-threads}
+from the tool bar or from @samp{GUD->GDB-MI} menu.
+
+ Stepping commands always apply to the current thread.
+
+@subsubheading Fine Thread Control
+
+ In non-stop mode, you can interrupt/continue your threads without
+selecting them. Hitting @kbd{i} in threads buffer interrupts thread
+under point, @kbd{c} continues it, @kbd{s} steps through. More such
+commands may be added in the future.
+
+Combined with creating bound buffers for any thread, this allows you
+to change and track state of many threads in the same time.
+
+ Note that when you interrupt a thread, it stops with @samp{signal
+received} reason. If that reason is included in your
+@code{gdb-switch-reasons} (it is by default), Emacs will switch to
+that thread.

+;;; Credits:
+
+;; This file was written by by Nick Roberts following the general design
+;; used in gdb-ui.el for Emacs 22.1 - 23.1. It is currently being developed
+;; by Dmitry Dzhus <dima@sphinx.net.ru> as part of the Google Summer
+;; of Code 2009 Project "Emacs GDB/MI migration".
+
+;;; Commentary:
+
+;; This mode acts as a graphical user interface to GDB. You can interact with
+;; GDB through the GUD buffer in the usual way, but there are also further
+;; buffers which control the execution and describe the state of your program.
+;; It separates the input/output of your program from that of GDB and displays
+;; expressions and their current values in their own buffers. It also uses
+;; features of Emacs 21 such as the fringe/display margin for breakpoints, and
+;; the toolbar (see the GDB Graphical Interface section in the Emacs info
+;; manual).
+
+;; M-x gdb will start the debugger.
+
+;; This file uses GDB/MI as the primary interface to GDB. It is still under
+;; development and is part of a process to migrate Emacs from annotations (as
+;; used in gdb-ui.el) to GDB/MI. It runs gdb with GDB/MI (-interp=mi) and
+;; access CLI using "-interpreter-exec console cli-command". This code works
+;; without gdb-ui.el and uses MI tokens instead of queues. Eventually MI
+;; should be asynchronous.
+
+;; This mode will PARTLY WORK WITH RECENT GDB RELEASES (status in modeline
+;; doesn't update properly when execution commands are issued from GUD buffer)
+;; and WORKS BEST when GDB runs asynchronously: maint set linux-async on.
+;;
+;; You need development version of GDB 7.0 for the thread buffer to work.
+
+;; This file replaces gdb-ui.el and is for development with GDB. Use the
+;; release branch of Emacs 22 for the latest version of gdb-ui.el.
+
+;; Windows Platforms:
+
+;; If you are using Emacs and GDB on Windows you will need to flush the buffer
+;; explicitly in your program if you want timely display of I/O in Emacs.
+;; Alternatively you can make the output stream unbuffered, for example, by
+;; using a macro:
+
+;; #ifdef UNBUFFERED
+;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
+;; #endif
+
+;; and compiling with -DUNBUFFERED while debugging.
+
+;; If you are using Cygwin GDB and find that the source is not being displayed
+;; in Emacs when you step through it, possible solutions are to:
+
+;; 1) Use Cygwin X Windows and Cygwin Emacs.
+;; (Since 22.1 Emacs builds under Cygwin.)
+;; 2) Use MinGW GDB instead.
+;; 3) Use cygwin-mount.el
+
+;;; Mac OSX:
+
+;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made
+;; some changes to the version that they include as part of Mac OSX.
+;; This requires GDB version 7.0 or later (estimated release date Aug 2009)
+;; as earlier versions don not compile on Mac OSX.
+
+;;; Known Bugs:
+
+;; 1) Stack buffer doesn't parse MI output if you stop in a routine without
+;; line information, e.g., a routine in libc (just a TODO item).
+
+;; TODO:
+;; 2) Watch windows to work with threads.
+;; 3) Use treebuffer.el instead of the speedbar for watch-expressions?
+;; 4) Mark breakpoint locations on scroll-bar of source buffer?

-
-;;; Commentary:
-
-;; This mode acts as a graphical user interface to GDB. You can interact with
-;; GDB through the GUD buffer in the usual way, but there are also further
-;; buffers which control the execution and describe the state of your program.
-;; It separates the input/output of your program from that of GDB, if
-;; required, and watches expressions in the speedbar. It also uses features of
-;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar
-;; (see the GDB Graphical Interface section in the Emacs info manual).
-
-;; By default, M-x gdb will start the debugger.
-
-;; This file has evolved from gdba.el that was included with GDB 5.0 and
-;; written by Tom Lord and Jim Kingdon. It uses GDB's annotation interface.
-;; You don't need to know about annotations to use this mode as a debugger,
-;; but if you are interested developing the mode itself, see the Annotations
-;; section in the GDB info manual.
-
-;; GDB developers plan to make the annotation interface obsolete. A new
-;; interface called GDB/MI (machine interface) has been designed to replace it.
-;; Some GDB/MI commands are used in this file through the CLI command
-;; 'interpreter mi <mi-command>'. To help with the process of fully migrating
-;; Emacs from annotations to GDB/MI, there is an experimental package called
-;; gdb-mi in the Emacs Lisp Package Archive ("http://tromey.com/elpa/"). It
-;; comprises of modified gud.el and a file called gdb-mi.el which replaces
-;; gdb-ui.el. When installed, this overrides the current files and invoking
-;; M-x gdb will use GDB/MI directly (starts with "gdb -i=mi"). When deleted
-;; ('d' followed by 'x' in Package Menu mode), the files are deleted and old
-;; functionality restored. This provides a convenient way to review the
-;; current status/contribute to its improvement. For someone who just wants to
-;; use GDB, however, the current mode in Emacs 22 is a much better option.
-;; There is also a file, also called gdb-mi.el, a version of which is included
-;; the GDB distribution. This will probably only work with versions
-;; distributed with GDB 6.5 or later. Unlike the version in ELPA it works on
-;; top of gdb-ui.el and you can only start it with M-x gdbmi.
-
-;; This mode SHOULD WORK WITH GDB 5.0 or later but you will NEED AT LEAST
-;; GDB 6.0 to use watch expressions. It works best with GDB 6.4 or later
-;; where watch expressions will update more quickly.
-
-;;; Windows Platforms:
-
-;; If you are using Emacs and GDB on Windows you will need to flush the buffer
-;; explicitly in your program if you want timely display of I/O in Emacs.
-;; Alternatively you can make the output stream unbuffered, for example, by
-;; using a macro:
-
-;; #ifdef UNBUFFERED
-;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
-;; #endif
-
-;; and compiling with -DUNBUFFERED while debugging.
-
-;; If you are using Cygwin GDB and find that the source is not being displayed
-;; in Emacs when you step through it, possible solutions are to:
-
-;; 1) Use Cygwin X Windows and Cygwin Emacs.
-;; (Since 22.1 Emacs builds under Cygwin.)
-;; 2) Use MinGW GDB instead.
-;; 3) Use cygwin-mount.el
-
-;;; Mac OSX:
-
-;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made
-;; some changes to the version that they include as part of Mac OSX.
-;; This requires GDB version 7.0 or later (estimated release date June 2009)
-;; as earlier versions don not compile on Mac OSX.
-
-;;; Known Bugs:
-
-;; 1) Cannot handle multiple debug sessions.
-;; 2) If you wish to call procedures from your program in GDB
-;; e.g "call myproc ()", "p mysquare (5)" then use level 2 annotations
-;; "gdb --annotate=2 myprog" to keep source buffer/selected frame fixed.
-;; 3) After detaching from a process, clicking on the "GO" icon on toolbar
-;; (gud-go) sends "continue" to GDB (should be "run").
-
-;;; TODO:
-
-;; 1) Use MI command -data-read-memory for memory window.
-;; 2) Use tree-buffer.el (from ECB) instead of the speedbar for
-;; watch-expressions? Handling of watch-expressions needs to be
-;; overhauled to work for large arrays/structures by creating variable
-;; objects for visible watch-expressions only.
-;; 3) Mark breakpoint locations on scroll-bar of source buffer?
