2019-08-16Remove "noerror" parameter from some TUI functionsTom Tromey5-41/+22
A few TUI functions take a "noerror" parameter. This is only checked in one spot: in tui_set_source_content, if noerror is false, and if an error occurs, then the function will call print_sys_errmsg. This seems misguided to me, so this patch removes that code and this parameter. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_update_source_window) (tui_update_source_window_as_is): Remove "noerror" parameter. * tui/tui-winsource.c (tui_update_source_window) (tui_update_source_window_as_is): Remove "noerror" parameter.

2019-08-16Remove separate visibility flagTom Tromey8-25/+26
TUI windows keep track of their visibility in a boolean field. However, this is not needed, because a window is visible if and only if it has an underlying curses handle. So, we can remove this separate field. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_is_window_visible): Update. * tui/tui-wingeneral.c (tui_make_window) (tui_gen_win_info::make_visible, tui_refresh_all): Update. * tui/tui-win.c (window_name_completer, tui_refresh_all_win) (tui_set_focus_command, tui_all_windows_info, update_tab_width) (tui_set_win_height_command, parse_scrolling_args): Update. * tui/tui-source.c (tui_source_window::style_changed): Update. * tui/tui-regs.c (tui_show_registers) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_check_register_values, tui_reg_command): Update. * tui/tui-disasm.c (tui_show_disassem): Update. * tui/tui-data.h (struct tui_gen_win_info) <is_visible>: New method. <is_visible>: Remove field. * tui/tui-data.c (tui_next_win, tui_prev_win) (tui_delete_invisible_windows): Update.
2019-08-16Remove m_has_locatorTom Tromey2-9/+0
The previous patch removed the only use of m_has_locator, so this member can now be removed. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <m_has_locator>: Remove. * tui/tui-layout.c (show_source_disasm_command, show_data) (show_source_or_disasm_and_command): Update.
2019-08-15TUI resize unificationTom Tromey13-173/+86
The TUI currently has two different ways to resize a window: the resize method, and the methods make_invisible_and_set_new_height and make_visible_with_new_height. There's no deep reason to have two different ways to resize a window, so this patch unifies them, leaving just the "resize" method. This also changes the locator to be handled more like an ordinary window and less like an adjunct of the associated source window. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-io.c (tui_puts_internal): Check TUI_CMD_WIN before calling update_cmdwin_start_line. * tui/tui-winsource.h (struct tui_source_window_base) <do_make_visible_with_new_height, set_new_height>: Don't declare. <rerender>: Declare. * tui/tui-winsource.c (tui_source_window_base::update_tab_width): Call rerender.

2019-08-15TUI window resize should not need invisibilityTom Tromey3-23/+63
When resizing a window, the TUI currently first makes it invisible, then changes the size, and then restores its visibility. I think this is done because curses doesn't truly support resizing a window -- there is a "wresize" extension, but the man page says it isn't available in all versions of curses. First, this is probably not a major problem any more. I imagine most of those old systems are gone now. Second, I think it's a better API to have this detail hidden inside of the resize method. This patch changes the code to follow this idea, and changes the ordinary resize method to use wresize when it is available. The special case for the command window is also moved to methods on the command window. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (show_layout, show_source_disasm_command) (show_data): Don't change window visibility. (tui_gen_win_info::resize): Remove special case for command window. Use wresize, when available. (show_source_or_disasm_and_command): Don't change window visibility. * tui/tui-command.h (struct tui_cmd_window) <resize>: Declare. <make_visible>: New method. * tui/tui-command.c (tui_cmd_window::resize): New method.
2019-08-15Change TUI source window iterationTom Tromey6-51/+79
Currently the TUI does separate bookkeeping to track which source windows exist. It seems better to me to just refer to the list of windows for this, so this patch removes the special handling and instead adds a new iterator. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_iterator): New. (struct tui_source_windows): New. * tui/tui-winsource.c (tui_display_main): Update. * tui/tui-win.c (tui_resize_all, tui_adjust_win_heights) (new_height_ok, parse_scrolling_args): Update. * tui/tui-layout.c (show_layout, show_data): Update. * tui/tui-data.h (tui_source_windows, tui_clear_source_windows) (tui_add_to_source_windows): Don't declare. * tui/tui-data.c (source_windows, tui_source_windows) (tui_clear_source_windows, tui_add_to_source_windows): Remove.
2019-08-15Rename the "reset" method to "resize"Tom Tromey4-47/+47
tui_gen_win_info::reset really just resizes the window. This patch renames it to reflect this. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <resize>: Rename from reset. * tui/tui-winsource.c (tui_source_window_base::resize): Rename. * tui/tui-layout.c (show_source_disasm_command, show_data): Update. (tui_gen_win_info::resize): Rename. (show_source_or_disasm_and_command): Update. * tui/tui-data.h (struct tui_gen_win_info) <resize>: Rename from reset.
2019-08-15Remove tui_initialize_static_dataTom Tromey3-18/+0
tui_initialize_static_data is not needed, because locator moving and resizing is already handled in the layout code. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_initialize_static_data): Remove. * tui/tui-interp.c (tui_interp::init): Don't call tui_initialize_static_data. * tui/tui-data.h (tui_initialize_static_data): Don't declare.
2019-08-15Minor simplification in tui_default_win_viewport_heightTom Tromey1-1/+1
tui_default_win_viewport_height doesn't need to look at tui_win_list; it can simply check the type directly. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (tui_default_win_viewport_height): Don't examine tui_win_list.
2019-08-15Remove tui_clear_source_contentTom Tromey3-24/+4
tui_clear_source_content is not needed. Instead, the callers can call erase_source_content, which is also changed to clear the content vector. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_clear_source_content): Don't declare. * tui/tui-winsource.c (tui_update_source_window_as_is): Don't call tui_clear_source_content. (tui_clear_source_content): Remove. (tui_source_window_base::do_erase_source_content): Hoist call to content.clear(). * tui/tui-stack.c (tui_show_frame_info): Don't call tui_clear_source_content.
2019-08-15Turn tui_erase_source_content into a methodTom Tromey5-30/+37
This changes tui_erase_source_content into a method on tui_source_window_base. The bulk of the work is moved into a helper method, so that the callers can each pass the string appropriate to the particular window class. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <do_erase_source_content>: New method. <erase_source_content>: New method. (tui_erase_source_content): Don't declare. * tui/tui-winsource.c (tui_clear_source_content): Update. (tui_source_window_base::do_erase_source_content): Rename from tui_erase_source_content. (tui_source_window_base::show_source_content): Update. * tui/tui-win.c (tui_resize_all, tui_adjust_win_heights): Update. * tui/tui-source.h (struct tui_source_window) <erase_source_content>: New method. * tui/tui-disasm.h (struct tui_disasm_window) <erase_source_content>: New method.
2019-08-15Remove tui_alloc_source_bufferTom Tromey4-26/+11
There is no longer any need for tui_alloc_source_buffer. The two callers of this function immediately change the contents of the window, undoing the work done by this function. This required adding a move constructor to tui_source_element -- a mildly surprising find, but without this, resizing the vector will cause crashes. This issue was masked earlier because tui_alloc_source_buffer handled this. Note that a patch for this bug was submitted here: https://sourceware.org/ml/gdb-patches/2019-08/msg00094.html That patch is better, IMO, but the author as yet hasn't responded to a request for a ChangeLog entry. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_alloc_source_buffer): Don't declare. (struct tui_source_element): Add DISABLE_COPY_AND_ASSIGN, and move constructor. * tui/tui-winsource.c (tui_alloc_source_buffer): Remove. * tui/tui-source.c (tui_set_source_content): Update. * tui/tui-disasm.c (tui_set_disassem_content): Update.
2019-08-15Change tui_line_is_displayed to be a methodTom Tromey4-32/+24
This changes tui_line_is_displayed to be a method on tui_source_window, now that it is obvious that it can only be called for this type. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_line_is_displayed): Don't declare. * tui/tui-winsource.c (tui_line_is_displayed): Move to tui-source.c. * tui/tui-source.h (struct tui_source_window) <line_is_displayed>: Declare. * tui/tui-source.c (tui_source_window::line_is_displayed): New method. (tui_source_window::maybe_update): Update.
2019-08-15Change tui_addr_is_displayed into a methodTom Tromey4-32/+24
This changes tui_addr_is_displayed to be a method on tui_disasm_window, now that it is obvious that it can only be called for this type. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_addr_is_displayed): Don't declare. * tui/tui-winsource.c (tui_addr_is_displayed): Move to tui-disasm.c. * tui/tui-disasm.h (struct tui_disasm_window) <addr_is_displayed>: Declare. * tui/tui-disasm.c (tui_disasm_window::addr_is_displayed): New method. (tui_disasm_window::maybe_update): Update.
2019-08-15Move contents of tui_show_frame_info to new methodTom Tromey6-57/+72
This moves much of the body of tui_show_frame_info to a new method on tui_source_window_base. This removes a check for the type of a window. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <maybe_update>: Declare. * tui/tui-stack.c (tui_show_frame_info): Call maybe_update method. * tui/tui-source.h (struct tui_source_window) <maybe_update>: Declare. * tui/tui-source.c (tui_source_window::maybe_update): New method. * tui/tui-disasm.h (struct tui_disasm_window) <maybe_update>: Declare. * tui/tui-disasm.c (tui_disasm_window::maybe_update): New method.
2019-08-15Avoid string_file in tui_make_status_lineTom Tromey1-5/+3
tui_make_status_line uses string_file where a simple std::string constructor would do. This makes this change. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_make_status_line): Use string constructor.
2019-08-15Move locator code to tui-stack.cTom Tromey5-50/+53
The locator is mostly implemented in tui-stack.c. This moves the remaining bits to tui-stack.c and tui-stack.h, as appropriate. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c: Include tui-stack.h. * tui/tui-stack.h (MAX_LOCATOR_ELEMENT_LEN) (struct tui_locator_window): Move from tui-data.h. * tui/tui-stack.c (_locator, tui_locator_win_info_ptr) (tui_initialize_static_data): Move from tui-data.c. * tui/tui-data.h (MAX_LOCATOR_ELEMENT_LEN) (struct tui_locator_window): Move to tui-stack.c. * tui/tui-data.c (_locator, tui_locator_win_info_ptr) (tui_initialize_static_data): Move to tui-stack.c.
2019-08-15Remove FIXMEs from tui-layout.cTom Tromey2-10/+2
An earlier patch added a couple of FIXME comments to tui-layout.c. This removes them. This is possible due to the previous patch that changed how boxing works in the TUI -- now, no special case for the command window is needed in box_win. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (show_source_disasm_command) (show_source_or_disasm_and_command): Use make_visible method, not tui_make_window. * tui/tui-command.h (struct tui_cmd_window) <make_visible>: Remove.
2019-08-15Simplify TUI boxingTom Tromey6-15/+23
In the TUI, whether or not a window can be boxed is a property of the window's type. This adds a can_box method to the window classes, and changes tui_make_window to defer to this, removing the "box_it" paramter. This also lets us remove "enum tui_box", as it is no longer used. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_window): Update. * tui/tui-wingeneral.c (tui_make_window): Remove "box_it" parameter. (tui_gen_win_info::make_visible): Update. * tui/tui-regs.c (tui_data_window::display_registers_from): Update. * tui/tui-layout.c (show_source_disasm_command) (show_source_or_disasm_and_command): Update. * tui/tui-data.h (struct tui_gen_win_info) <can_box>: New method. (enum tui_box): Remove. (struct tui_win_info) <can_box>: New method. * tui/tui-command.h (struct tui_cmd_window) <can_box>: New method.
2019-08-13Remove tui_gen_win_info::last_visible_lineTom Tromey2-4/+1
The last_visible_line field of tui_gen_win_info is not used, so remove it. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-data.h (struct tui_gen_win_info) <last_visible_line>: Remove. * tui/tui-data.c (tui_initialize_static_data): Update.
2019-08-13Don't track the contents of the execution info windowTom Tromey2-70/+8
The curses library keeps track of the contents of each window, and can redraw the screen as needed. This means that in most cases is no need for the TUI windows to also keep track of their contents. This patch removes content tracking from the execution window, leaving that to curses. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_exec_info_window) <~tui_exec_info_window, maybe_allocate_content, get_content, m_content>: Remove. (struct tui_source_window_base) <set_exec_info_content, show_exec_info_content>: Don't declare. * tui/tui-winsource.c (tui_exec_info_window::maybe_allocate_content): Remove. (tui_source_window_base::update_exec_info): Rename from set_exec_info_content. (tui_source_window_base::show_exec_info_content) (tui_source_window_base::update_exec_info): Remove.
2019-08-13Remove tui_clear_exec_info_contentTom Tromey2-18/+7
After the previous patch, all calls to tui_clear_exec_info_content come just after a call to tui_clear_source_content. Because these two windows are linked, I think it makes sense to have tui_clear_source_content simply do the work. So, this patch removes tui_clear_exec_info_content. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_clear_exec_info_content): Don't declare. * tui/tui-winsource.c (tui_update_source_window_as_is) (tui_update_source_windows_with_addr, tui_erase_source_content): Update. (tui_clear_exec_info_content): Remove.
2019-08-13Remove tui_erase_exec_info_contentTom Tromey2-9/+1
One call to tui_erase_exec_info_content can be removed. This call is not needed because the function in question then immediately sets the execution info window contents. Once this is done, tui_clear_exec_info_content is just a wrapper for the only call to tui_erase_exec_info_content, so tui_erase_exec_info_content can be renamed and the wrapper function removed. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_erase_exec_info_content): Don't declare. * tui/tui-winsource.c (tui_source_window_base::refresh_all): Don't call tui_erase_exec_info_content. (tui_clear_exec_info_content): Rename from tui_erase_exec_info_content. (tui_clear_exec_info_content): Delete.
2019-08-13Turn tui_show_exec_info_content into a methodTom Tromey2-7/+9
This changes tui_show_exec_info_content to be a method on tui_source_window_base. As it is only called by other methods on this class, it can be private. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <show_exec_info_content>: Declare. (tui_show_exec_info_content): Don't declare. * tui/tui-winsource.c (tui_source_window_base::show_exec_info_content): Rename from tui_show_exec_info_content. (tui_source_window_base::update_exec_info): Update.
2019-08-13Move code to tui-winsource.hTom Tromey2-41/+41
This moves code related to the execution info window from tui-data.h to tui-winsource.h. It fits better here because the execution info is conceptually part of the source and disassembly windows, and tui-winsource.h is where this common class lives. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-data.h (enum tui_bp_flag, tui_bp_flags, struct tui_source_element) (TUI_BP_HIT_POS, TUI_BP_BREAK_POS, TUI_EXEC_POS) (TUI_EXECINFO_SIZE, tui_exec_info_content): Move ... * tui/tui-winsource.h (enum tui_bp_flag, tui_bp_flags, struct tui_source_element, TUI_BP_HIT_POS, TUI_BP_BREAK_POS) (TUI_EXEC_POS, TUI_EXECINFO_SIZE, tui_exec_info_content): ... here.
2019-08-13Change tui_update_exec_info to be a methodTom Tromey3-9/+9
This changes tui_update_exec_info to be a method on tui_source_window_base. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <update_exec_info>: Declare.

(tui_source_window_base::update_exec_info): Rename from tui_update_exec_info. * tui/tui-stack.c (tui_show_frame_info): Update.
2019-08-13Change tui_set_exec_info_content to be a methodTom Tromey2-9/+10
This changes tui_set_exec_info_content to bea method on tui_source_window_base. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <set_exec_info_content>: Declare. (tui_set_exec_info_content): Don't declare. * tui/tui-winsource.c (tui_source_window_base::set_exec_info_content): Rename from tui_set_exec_info_content. (tui_update_exec_info): Update.
2019-08-13Change tui_show_source_content to be a methodTom Tromey3-13/+14
This changes tui_show_source_content to be a method on tui_source_window_base. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <show_source_content>: Declare.

(tui_source_window_base::refresh_all): Update. * tui/tui-layout.c (show_source_disasm_command) (show_source_or_disasm_and_command): Update.
2019-08-13Change tui_check_and_display_highlight_if_needed to be a methodTom Tromey6-15/+15
This changes tui_check_and_display_highlight_if_needed to be a method on tui_win_info. This makes it clear that the NULL check in that function is not needed, so it is removed here. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_erase_source_content) (tui_show_source_content, tui_source_window_base::refresh_all): Update. * tui/tui-wingeneral.h (tui_check_and_display_highlight_if_needed): Don't declare. * tui/tui-wingeneral.c (tui_win_info::check_and_display_highlight_if_needed): Rename from check_and_display_highlight_if_needed. * tui/tui-win.c (tui_rehighlight_all) (tui_win_info::make_visible_with_new_height): Update. * tui/tui-regs.c (tui_data_window::display_registers_from_line) (tui_data_window::erase_data_content) (tui_data_window::display_all_data): Update. * tui/tui-data.h (struct tui_win_info) <check_and_display_highlight_if_needed>: Declare.
2019-08-13Delete invisible TUI windowsTom Tromey4-13/+32
This changes the TUI so that when the layout changes, any windows that are invisible are now deleted. This makes it simpler to understand window lifetimes. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_resize_all): Call tui_delete_invisible_windows. * tui/tui-layout.c (show_layout): Call tui_delete_invisible_windows. * tui/tui-data.h (tui_delete_invisible_windows): Declare. * tui/tui-data.c (tui_delete_invisible_windows): New function.
2019-08-13Simplify tui_show_disassemTom Tromey1-1/+2
tui_show_disassem does not need to call tui_add_win_to_layout, because the callers that could change the layout have already ensured that it exists. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-disasm.c (tui_show_disassem): Add assertion. Don't call tui_add_win_to_layout.

tui_default_win_height is only used in tui-layout.c, so make it static. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-layout.h (tui_default_win_height): Don't declare. * tui/tui-layout.c (tui_default_win_height): Now static.
2019-08-13Two simplifications in tui-layout.cTom Tromey1-119/+109
This patch simplifies some code in tui-layout.c. In show_layout, all the layout settings can be handled by a single switch statement. In show_source_disasm_command and show_source_or_disasm_and_command, there is no need to check the current layout, as the caller has already done so. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (show_layout): Unify all layout cases into a single switch. (show_source_disasm_command, show_source_or_disasm_and_command): Don't check current layout.
2019-08-13Simplify tui_make_all_invisibleTom Tromey3-16/+9
This simplifies the implementation of tui_make_all_invisible. Also, because show_data is only called by show_layout, this hoists the call to tui_make_all_invisible and removes the call from show_data. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (make_all_visible): Remove. (tui_make_all_invisible): Simplify. * tui/tui-layout.c (tui_make_all_invisible): Move from tui-wingeneral.c; simplify. (show_layout): Hoist call to tui_make_all_invisible. (show_data): Don't call tui_make_all_invisible.

2019-08-13Move current_layout to tui-layout.cTom Tromey3-21/+12
This moves the current_layout global to tui-layout.c. This allows for the removal of an accessor function; but also it just seems clearer to have it here. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-layout.c (current_layout, tui_current_layout): Move from tui-data.c.

2019-08-07Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers1-3/+3
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

2019-08-06Add file offsets to the source cacheTom Tromey1-1/+3
Currently, gdb stores the number of lines and an array of file offsets for the start of each line in struct symtab. This patch moves this information to the source cache. This has two benefits. First, it allows gdb to read a source file less frequently. Currently, a source file may be read multiple times: once when computing the file offsets, once when highlighting, and then pieces may be read again while printing source lines. With this change, the file is read once for its source text and file offsets; and then perhaps read again if it is evicted from the cache. Second, if multiple symtabs cover the same source file, then this will share the file offsets between them. I'm not sure whether this happens in practice. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * annotate.c (annotate_source_line): Use g_source_cache. * source-cache.c (source_cache::get_plain_source_lines): Change parameters.
