| d94dccc6 | 28 | ;; This mode acts as a graphical user interface to GDB. You can interact with |
| 1ffac268 NR |
29 | ;; GDB through the GUD buffer in the usual way, but there are also further |
| 30 | ;; buffers which control the execution and describe the state of your program. | |
| 614963ba | 31 | ;; It separates the input/output of your program from that of GDB, if |
| d94dccc6 | 32 | ;; required, and watches expressions in the speedbar. It also uses features of |
| 2101105e NR |
33 | ;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar |
| 34 | ;; (see the GDB Graphical Interface section in the Emacs info manual). | |
| 1ffac268 | 35 | |
| b6d0e4da NR |
36 | ;; By default, M-x gdb will start the debugger. However, if you have customised |
| 37 | ;; gud-gdb-command-name, then start it with M-x gdba. | |
| 38 | ||
| 39 | ;; This file has evolved from gdba.el that was included with GDB 5.0 and | |
| 40 | ;; written by Tom Lord and Jim Kingdon. It uses GDB's annotation interface. | |
| 41 | ;; You don't need to know about annotations to use this mode as a debugger, | |
| 42 | ;; but if you are interested developing the mode itself, then see the | |
| 43 | ;; Annotations section in the GDB info manual. | |
| f2f82fa4 | 44 | ;; |
| d94dccc6 | 45 | ;; GDB developers plan to make the annotation interface obsolete. A new |
| f2f82fa4 | 46 | ;; interface called GDB/MI (machine interface) has been designed to replace |
| d94dccc6 | 47 | ;; it. Some GDB/MI commands are used in this file through the CLI command |
| b6d0e4da NR |
48 | ;; 'interpreter mi <mi-command>'. A file called gdb-mi.el is included with |
| 49 | ;; GDB (6.2 onwards) that uses GDB/MI as the primary interface to GDB. It is | |
| 50 | ;; still under development and is part of a process to migrate Emacs from | |
| 51 | ;; annotations to GDB/MI. | |

| 53 | ;; Known Bugs: | |
| 54 | ;; | |
| b6d0e4da | 55 | ;; TODO: |
| 37ebd64b NR |
56 | ;; 1) Use MI command -data-read-memory for memory window. |
| 57 | ;; 2) Highlight changed register values (use MI commands | |
| 58 | ;; -data-list-register-values and -data-list-changed-registers instead | |
| 59 | ;; of 'info registers'. | |
| 60 | ;; 3) Use tree-widget.el instead of the speedbar for watch-expressions? | |
| 61 | ;; 4) Mark breakpoint locations on scroll-bar of source buffer? | |
| bf247b6e | 62 | ;; 5) After release of 22.1 use '-var-list-children --all-values' |
| 37ebd64b | 63 | ;; and '-stack-list-locals 2' which need GDB 6.1 onwards. |
