;; 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.
;; 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>'. A file called gdb-mi.el is included with
-;; GDB (6.2 onwards) that 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 to GDB/MI.
+;; 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
;; 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
+
;;; Known Bugs:
-;; 1) Strings that are watched don't update in the speedbar when their
-;; contents change unless the first character changes.
-;; 2) Cannot handle multiple debug sessions.
-;; 3) M-x gdb doesn't work with "run" command in .gdbinit, use M-x gdba instead.
-;; 4) M-x gdb doesn't work if the corefile is specified in the command in the
-;; minibuffer, use M-x gdba instead (or specify the core in the GUD buffer).
-;; 5) If you wish to call procedures from your program in GDB
+;; 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.
-;; 6) After detaching from a process, clicking on the "GO" icon on toolbar
+;; 3) After detaching from a process, clicking on the "GO" icon on toolbar
;; (gud-go) sends "continue" to GDB (should be "run").
-;;; Problems with watch expressions, GDB/MI:
-
-;; 1) They go out of scope when the inferior is re-run.
-;; 2) -stack-list-locals has a type field but also prints type in values field.
-;; 3) VARNUM increments even when variable object is not created
-;; (maybe trivial).
-
;;; TODO:
;; 1) Use MI command -data-read-memory for memory window.
-;; 2) Use tree-widget.el instead of the speedbar for watch-expressions?
+;; 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?
