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).
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.
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.
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.
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.
58 ;;; Windows Platforms:
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
66 ;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
69 ;; and compiling with -DUNBUFFERED while debugging.
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!).
80 ;;; Problems with watch expressions, GDB/MI:
81 ;; 1) They go out of scope when the inferior is re-run.
82 ;; 2) -stack-list-locals has a type field but also prints type in values field.
83 ;; 3) VARNUM increments even when variable object is not created
87 ;; 1) M-x gdb doesn't work with "run" command in .gdbinit, use M-x gdba instead.
90 ;; 1) Use MI command -data-read-memory for memory window.
91 ;; 2) Use tree-widget.el instead of the speedbar for watch-expressions?
92 ;; 3) Mark breakpoint locations on scroll-bar of source buffer?
93 ;; 4) With gud-print and gud-pstar, print the variable name in the GUD
94 ;; buffer instead of the value's history number.
