|
||
|
||
;;; 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. However, if you have customised
|
||
;; gud-gdb-command-name, then start it with M-x gdba.
|
||
|
||
;; 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, then 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>'. 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.
|
||
|
||
;; This mode SHOULD WORK WITH GDB 5.0 onwards but you will NEED GDB 6.0
|
||
;; onwards to use watch expressions. It works best with GDB 6.4 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.
|
||
|
||
;;; 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
|
||
;; e.g "call myproc ()", "p mysquare (5)" then use level 2 annotations
|
||
;; "gdb --annotate=2 myprog" to keep source buffer/selected frame fixed.
|
||
|
||
;;; 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?
|
||
;; 3) Mark breakpoint locations on scroll-bar of source buffer?
