Remove indirection from tui_data_window::regs_content
tui_data_window::regs_content is currently a vector of unique_ptr. However, due to the way this is managed now, there is no need to keep the pointers -- it can simply be a vector of the objects themselves. This patch removes this extra layer of indirection. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-regs.h (struct tui_data_window): Use DISABLE_COPY_AND_ASSIGN. <regs_content>: Change type, removing unique_ptr. <tui_data_window>: Add move constructor. * tui/tui-regs.c (tui_data_window::show_registers) (tui_data_window::show_register_group) (tui_data_window::display_registers_from) (tui_data_window::display_registers_from) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_data_window::rerender, tui_data_window::refresh_window) (tui_data_window::check_register_values): Update.
