From 5104fe361d818a46b262b5d504f3d293c9a2b44a Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Tue, 2 Jul 2019 17:07:02 -0600 Subject: [PATCH] Move source window common to code to tui-winsource.[ch] Like the previous rearranging patches, this moves the source and disassembly window base class code to tui-winsource.[ch]. The execution info window is also moved, because it is associated with this base class. gdb/ChangeLog 2019-07-17 Tom Tromey * tui/tui-winsource.h (struct tui_exec_info_window) (struct tui_source_window_base): Move from tui-data.h. * tui/tui-winsource.c: Move many method definitions from elsewhere. Remove "structuring" comments. * tui/tui-wingeneral.c (tui_source_window_base::make_visible) (tui_source_window_base::refresh_window): Move to tui-winsource.c. * tui/tui-win.c (tui_source_window_base::refresh_all) (tui_source_window_base::update_tab_width) (tui_source_window_base::set_new_height) (tui_source_window_base::do_make_visible_with_new_height): Move to tui-winsource.c. * tui/tui-source.h: Update. * tui/tui-source.c (tui_source_window_base::reset): Move to tui-winsource.c. * tui/tui-disasm.h: Update. * tui/tui-data.h (struct tui_exec_info_window): Move to tui-winsource.h. (struct tui_source_window_base): Likewise. * tui/tui-data.c (tui_source_window_base::clear_detail) (tui_source_window_base, ~tui_source_window_base): Move to tui-winsource.c. --- gdb/ChangeLog | 25 +++++++ gdb/tui/tui-data.c | 27 +------ gdb/tui/tui-data.h | 85 +--------------------- gdb/tui/tui-disasm.h | 1 + gdb/tui/tui-source.c | 9 --- gdb/tui/tui-source.h | 3 + gdb/tui/tui-win.c | 90 ----------------------- gdb/tui/tui-wingeneral.c | 18 ----- gdb/tui/tui-winsource.c | 149 +++++++++++++++++++++++++++++++++++++-- gdb/tui/tui-winsource.h | 82 ++++++++++++++++++++- 10 files changed, 256 insertions(+), 233 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 3c263816fd1..77a9f9e86eb 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,28 @@ +2019-07-17 Tom Tromey + + * tui/tui-winsource.h (struct tui_exec_info_window) + (struct tui_source_window_base): Move from tui-data.h. + * tui/tui-winsource.c: Move many method definitions from + elsewhere.
