(gdb-source-info): Check for preprocessor info. (gdb-tooltip-print-1): New function. Don't print tooltip if it is a macro for a function. found (user might have used GDB dir command). (gdb-info-breakpoints-custom): Try to find file again if not already (gdb-get-location): Update gdb-location-alist correctly for change to gdb-info-breakpoints-custom.

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