Unify the behavior of source buffer display for gdb-mi. Before this change, stepping and other gdb command handlers use 'gud-display-line', and 'gdb-goto-breakpoint' uses 'gdb-display-source-buffer'. Now whenever gdb-mi code tries to open a source buffer, 'gdb-display-source-buffer' is used. Also, simplify the logic in 'gdb-display-source-buffer' and add a feature to limit the maximum number of source windows. * doc/emacs/building.texi (GDB User Interface Layout): Explain source file display in GDB. * etc/NEWS (gdb-mi): Add news about source display. * lisp/progmodes/gdb-mi.el (gdb-source-window): Remove variable, change to 'gdb-source-window-list'. (gdb-source-window-list): New variable. (gdb-display-source-buffer-action, gdb-max-source-window-count): New options. (gdb-init-1, gdb-setup-windows, gdb-load-window-configuration, gdb-restore-windows): Use 'gdb-source-window' rather than 'gdb-source-window-list'. (gdb-save-window-configuration): Use 'gdb-source-window' rather than 'gdb-source-window-list'. And consider any buffer that is not a command or function buffer as a source buffer. (gdb-display-source-buffer): Use new logic. (gdb-goto-breakpoint): Remove 'display-buffer' call and don't set 'gdb-source-buffer' anymore. * lisp/progmodes/gud.el (gud-display-line): If used by gdb-mi, use 'gdb-display-source-buffer' rather than 'display-buffer'. Don't set 'gdb-source-buffer' anymore. |
