  27 ;;; Commentary:
  28
  29 ;; This mode acts as a graphical user interface to GDB.  You can interact with
  30 ;; GDB through the GUD buffer in the usual way, but there are also further
  31 ;; buffers which control the execution and describe the state of your program.
  32 ;; It separates the input/output of your program from that of GDB, if
  33 ;; required, and watches expressions in the speedbar.  It also uses features of
  34 ;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar
  35 ;; (see the GDB Graphical Interface section in the Emacs info manual).
  36
  37 ;; By default, M-x gdb will start the debugger. However, if you have customised
  38 ;; gud-gdb-command-name, then start it with M-x gdba.
  39
  40 ;; This file has evolved from gdba.el that was included with GDB 5.0 and
  41 ;; written by Tom Lord and Jim Kingdon.  It uses GDB's annotation interface.
  42 ;; You don't need to know about annotations to use this mode as a debugger,
  43 ;; but if you are interested developing the mode itself, then see the
  44 ;; Annotations section in the GDB info manual.
  45
  46 ;; GDB developers plan to make the annotation interface obsolete.  A new
  47 ;; interface called GDB/MI (machine interface) has been designed to replace
  48 ;; it.  Some GDB/MI commands are used in this file through the CLI command
  49 ;; 'interpreter mi <mi-command>'.  A file called gdb-mi.el is included with
  50 ;; GDB (6.2 onwards) that uses GDB/MI as the primary interface to GDB.  It is
  51 ;; still under development and is part of a process to migrate Emacs from
  52 ;; annotations to GDB/MI.
  53
  54 ;; This mode SHOULD WORK WITH GDB 5.0 onwards but you will NEED GDB 6.0
  55 ;; onwards to use watch expressions.  It works best with GDB 6.4 where
  56 ;; watch expressions will update more quickly.
  57
  58 ;;; Windows Platforms:
  59
  60 ;; If you are using Emacs and GDB on Windows you will need to flush the buffer
  61 ;; explicitly in your program if you want timely display of I/O in Emacs.
  62 ;; Alternatively you can make the output stream unbuffered, for example, by
  63 ;; using a macro:
  64
  65 ;;           #ifdef UNBUFFERED
  66 ;;           setvbuf (stdout, (char *) NULL, _IONBF, 0);
  67 ;;           #endif
  68
  69 ;; and compiling with -DUNBUFFERED while debugging.
  70
  71 ;;; Known Bugs:
  72
  73 ;; 1) Strings that are watched don't update in the speedbar when their
  74 ;; contents change unless the first character changes.
  75 ;; 2) Cannot handle multiple debug sessions.
  76 ;; 3) Initially, the assembler buffer does not display the cursor at the
  77 ;; current line if the line is not visible in the window (but when testing
  78 ;; gdb-assembler-custom with a lisp debugger it does!).
  79
  80 ;;; Problems with watch expressions, GDB/MI:
  81
  82 ;; 1) They go out of scope when the inferior is re-run.
  83 ;; 2) -stack-list-locals has a type field but also prints type in values field.
  84 ;; 3) VARNUM increments even when vairable object is not created (maybe trivial).
  85
  86 ;;; TODO:
  87
  88 ;; 1) Use MI command -data-read-memory for memory window.
  89 ;; 2) Use tree-widget.el instead of the speedbar for watch-expressions?
  90 ;; 3) Mark breakpoint locations on scroll-bar of source buffer?
  91 ;; 4) With gud-print and gud-pstar, print the variable name in the GUD
  92 ;;    buffer instead of the value's history number.

 212 If `gdb-many-windows' is nil (the default value) then gdb just
 213 pops up the GUD buffer unless `gdb-show-main' is t.  In this case
 214 it starts with two windows: one displaying the GUD buffer and the
 215 other with the source file with the main routine of the inferior.
 216
 217 If `gdb-many-windows' is t, regardless of the value of
 218 `gdb-show-main', the layout below will appear unless
 219 `gdb-use-separate-io-buffer' is nil when the source buffer
 220 occupies the full width of the frame.  Keybindings are shown in
 221 some of the buffers.
 222
 223 Watch expressions appear in the speedbar/slowbar.
 224
 225 The following commands help control operation :
 226
 227 `gdb-many-windows'    - Toggle the number of windows gdb uses.
 228 `gdb-restore-windows' - To restore the window layout.
