From 398fdd6086a290748afcce0efabaebb4e363278c Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 12 Jul 2019 18:18:10 -0600 Subject: Remove the TUI execution info window The TUI execution info window is unusual in that it is always linked to a source or disassembly window. Even updates of its content are handled by the source window, so it really has no life of its own. This patch removes this window entirely and puts its functionality directly into the source window. This simplifies the code somewhat. This is a user-visible change, because now the box around the source (or disassembly) window encloses the execution info as well. I consider this an improvement as well, though. Note that this patch caused ncurses to start emitting the "CSI Z" sequence, so I've added this to the test suite terminal implementation. gdb/ChangeLog 2019-08-16 Tom Tromey * tui/tui.h (enum tui_win_type) : Remove. * tui/tui-winsource.h (struct tui_exec_info_window): Remove.
