Subject: [RFA v2 13/24] Replace tui_restore_gdbout with scoped_restore
Date: Tue, 25 Jul 2017 17:27:00 -0000 [thread overview]
Message-ID: <20170725172107.9799-14-tom@tromey.com> (raw)
In-Reply-To: <20170725172107.9799-1-tom@tromey.com>
This patch replaces tui_restore_gdbout (a cleaup function) with a use
of scoped_restore. This one is broken out into its own patch because
it might slightly change the behavior of gdb: it saves and restores
pagination_enabled, whereas the tui_restore_gdbout unconditionally set
pagination_enabled to 1; and I think this warrants closer review.
ChangeLog
2017-07-25 Tom Tromey <tom@tromey.com>
* tui/tui-regs.c (tui_restore_gdbout): Remove.
(tui_register_format): Use scoped_restore.
