This adds a new command, "tui new-layout". This command can be used
to define a new TUI window layout.
The command is used like:
(gdb) tui new-layout name src 1 regs 1 status 0 cmd 1
The first argument is the name of the layout. In this example, it is
"name", so the new layout could be seen by "layout name".
Subsequent arguments come in pairs, where the first item in a pair is
the name of a window, and the second item in a pair is the window's
weight. A weight is just an integer -- a window's allocated size is
proportional to the total of the weights given. So, in the above
example, all windows will have the same size (the status windows's
weight does not matter, because it has fixed height).

This changes the TUI so that the available layouts are no longer
completely hard-coded. "enum tui_layout_type" is removed, and then
all the fallout from this is fixed up.
This patch also reimplements the "layout" command to be a prefix
command. The concrete layouts are simply sub-commands now. This
provides completion and correct abbreviation behavior for free.
Finally, this also changes the name of the locator window to "status".
This matches the documentation and will be exposed to the user in a
subsequent patch.

This reimplements the low-level layout function that is used by the
"tui reg" command. Now it simply calls into the existing "layout"
command, though this will be changed again in a subsequent patch. The
rationale for this patch is that it makes it simpler to remove
"enum tui_layout_type".

The TUI "C-x 1" key binding removes TUI windows, based on the current
layout. With user-defined layouts, this is no longer easy to do.
This patch changes "C-x 1" to simply delete windows, leaving just the

The TUI "C-x 2" binding tries to switch to a different layout based on
the current layout. Once user-defined layouts are available, this
won't really make sense. I wasn't entirely sure how to handle this.
This patch changes the binding to simply cycle through the existing
layouts. I considered this a reasonable, though not ideal,
compromise.

tui_data_window creates new curses windows, but does not pass in
coordinates relative to the data window's origin. This means that the
data window could only ever be displayed as the topmost window in a
layout. This is not a currently problem, because all the existing
layouts do this; but a subsequent patch will add user-defined layouts,
which could do otherwise.

The source_cache::ensure method may throw an exception through
the invocation of source_cache::get_plain_source_lines. This
happens when the source file is not found. The expected behaviour
of "ensure" is only returning "true" or "false" according to the
documentation in the header file.
So far, if gdb is in source layout and a file is missing, you see
some outputs like below:
,---------------------------------------------.
| test.c file is loaded in the source window. |
| |
| int main() |
| ... |
|---------------------------------------------|
| Remote debugging using :1234 |
| __start () at /path/to/crt0.S:141 |

| (gdb) p/x $pc |
| $2 = 0x128 |
| (gdb) [pressing arrow-down key] |
| (gdb) terminate called after throwing an |
| instance of 'gdb_exception_error' |
`---------------------------------------------'
Other issues have been encountered as well [1].
The patch from Pedro [2] which is about preventing exceptions
from crossing the "readline" mitigates the situation by not
causing gdb crash, but still there are lots of errors printed:
,---------------------------------------------.
| test.c file is loaded in the source window. |
| |
| int main() |
| ... |

| /path/to/crt0.S: No such file or directory. |
| (gdb) [pressing arrow-up key] |
| /path/to/crt0.S: No such file or directory. |
`---------------------------------------------'
With the changes of this patch, the behavior is like:
,---------------------------------------------.
| initially, source window is empty because |
| crt0.S is not found and according to the |
| program counter that is the piece of code |
| being executed. |
| |
| later, when we break at main (see commands |
| below), this window will be filled with the |
| the contents of test.c file. |

There is no crash and the error message is completely
gone. Maybe it is good practice that the error is
shown inside the source window.
I tested this change against gdb.base/list-missing-source.exp
and there was no regression.

In TUI mode, if the disassembly output for the program is less than
one screen long, then currently if the user scrolls down until on the
last assembly instruction is displayed and then tries to scroll up
using Page-Up, the display doesn't update - they are stuck viewing the
last line.
If the user tries to scroll up using the Up-Arrow, then the display
scrolls normally.
What is happening is on the Page-Up we ask GDB to scroll backward the
same number of lines as the height of the TUI ASM window. The back
scanner, which looks for a good place to start disassembling, fails to
find a starting address which will provide the requested number of new
lines before we get back to the original starting address (which is
not surprising, our whole program contains less than a screen height
of instructions), as a result the back scanner gives up and returns
the original starting address.
When we scroll with Up-Arrow we only ask the back scanner to find 1
new instruction, which it manages to do, so this scroll works.
The solution here is, when we fail to find enough instructions, to
return the lowest address we did manage to find. This will ensure we
jump to the lowest possible address in the disassembly output.

GDB has some commands ('+', '-', '<', and '>') for scrolling the SRC
and ASM TUI windows from the CMD window, however the help text for
these commands lists the arguments in the wrong order.
This commit updates the help text to match how GDB actually works, and
also extends the text to describe what the arguments mean, and what
the defaults are.
There should be no change in GDBs functionality after this commit.

This started as a patch to enable the asm window to handle attempts to
disassemble invalid memory, but it ended up expanding into a
significant rewrite of how the asm window handles scrolling. These
two things ended up being tied together as it was impossible to
correctly test scrolling into invalid memory when the asm window would
randomly behave weirdly while scrolling.
Things that should work nicely now; scrolling to the bottom or top of
the listing with PageUp, PageDown, Up Arrow, Down Arrow and we should
be able to scroll past small areas of memory that don't have symbols
associated with them. It should also be possible to scroll to the
start of a section even if there's no symbol at the start of the
section.
Adding tests for this scrolling was a little bit of a problem. First
I would have liked to add tests for PageUp / PageDown, but the tuiterm
library we use doesn't support these commands right now due to only
emulating a basic ascii terminal. Changing this to emulate a more
complex terminal would require adding support for more escape sequence
control codes, so I've not tried to tackle that in this patch.
Next, I would have liked to test scrolling to the start or end of the
assembler listing and then trying to scroll even more, however, this
is a problem because in a well behaving GDB a scroll at the start/end
has no effect. What we need to do is:
- Move to start of assembler listing,
- Send scroll up command,
- Wait for all curses output,
- Ensure the assembler listing is unchanged, we're still at the
start of the listing.
The problem is that there is no curses output, so how long do we wait
at step 3? The same problem exists for scrolling to the bottom of the
assembler listing. However, when scrolling down you can at least see
the end coming, so I added a test for this case, however, this feels
like an area of code that is massively under tested.

In some cases, the TUI flickers when redrawing. This can be seen
mostly easily when switching layouts.
This patch fixes the problem by exploiting the double buffering that
curses already does. In some spots, the TUI will now disable flushing
the curses buffers to the screen; and then flush them all at once when
the rendering is complete.

I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:
commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
Author: John Baldwin <jhb@FreeBSD.org>
Date: Sat Sep 9 11:02:37 2017 -0700

I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

When adding support for styling the TUI borders, I neglected to have
this code check cli_styling. As a result, "set style enabled off"
does not affect the borders.
This patch fixes this oversight. While doing this, I found that
running gdb without an executable, enabling the TUI, and then trying
"set style enabled off" would fail with the mysterious "No registers".
The fix for this is to use deprecated_safe_get_selected_frame in
tui_source_window_base::refill.

Until recently when the source window was scrolled the assembler
window would scroll in sync - keeping the disassembly for the current
line in view.
This was broken in commit:
commit b4b49dcbff6b437fa8b4e2fc0c3f27b457f11310
Date: Wed Nov 13 16:47:58 2019 -0700
Don't call tui_show_source from tui_ui_out
This commit restores the synchronised scrolling and also maintains the
horizontal scroll within the source view when it is vertically
scrolled, something that was broken before.
This commit does not mean that scrolling the assembler view scrolls
the source view. The connection this way never existed, though maybe
it should, but I'll leave adding this feature for a separate commit.

* tui/tui-source.c (tui_source_window::do_scroll_vertical): Update
all source windows, and maintain horizontal scroll status while
doing so.

Hannes Domani pointed out that my previous patch to fix the "list"
command in the TUI instead broke vertical scrolling. While looking at
this, I found that do_scroll_vertical calls print_source_lines, which
seems like a very roundabout way to change the source window. This
patch removes this oddity and fixes the bug at the same time.
I've added a new test case. This is somewhat tricky, because the
obvious approach of sending a dummy command after the scroll did not
work -- due to how the TUI works, sennding a command causes the scroll
to take effect.

Currently if a user starts the tui with 'layout asm' then they will be
presented with the 'src' layout.
What happens is:
1. Layout command enables TUI, selecting the SRC layout by default.
2. As part of tui_enable we call tui_display_main, which calls
tui_get_begin_asm_address, which calls
set_default_source_symtab_and_line. This changes core GDBs
current symtab and line, which triggers a call to the symtab
changed hook tui_symtab_changed, which sets the flag
from_source_symtab.
3. Back in the layout command, the layout is changed from SRC to
ASM. After this the layout command completes and we return to
core GDB which prints the prompt, however...
4. The before prompt hook is called which sees the
from_source_symtab flag is set and forces the SRC window to be
displayed. This switches us back to SRC view.
The solution I propose here is to delay installing the hooks into core
GDB until after we have finished setting up the tui and selecting the
default frame to view. In this way we effectively ignore the first
symtab changed event triggered when making main the default symtab.

tui_display_main.

In tui_disasm_window::addr_is_displayed(), there can be situations
where "content" is empty. For instance, it can happen when the
"content" was not filled in tui_disasm_window::set_contents(),
because tui_disassemble() threw an exception. Usually this exception
is the result of fetching invalid PC addresses like the ones beyond
the end of the program.
Having "content.size ()" zero leads to an overflow in this condition
check inside tui_disasm_window::addr_is_displayed():
int i = 0;
while (i < content.size () - threshold ...) {
... content[i] ...
}
"threshold" is 2 and there are times that "content.size ()" is 0.
This results into an overflow and the loop is entered whereas it
should have been skipped. Finally, "content[i]" access leads to
a segmentation fault.
Same problem applies to tui_source_window::line_is_displayed().
The issue has been discussed at length in bug 25345:
https://sourceware.org/bugzilla/show_bug.cgi?id=25345
This commit avoids the segmentation faults with an early check:
if (content.size () < SCROLL_THRESHOLD)
return false;
Moreover, those functions have been overhauled to a leaner code.

When calling tui_add_win_to_layout, use tui_set_layout not show_layout
so that window focus is correctly updated. If the focus is not
correctly maintained then GDB can be crashed like this:
start
tui enable
layout asm
list SOME_FUNCTION
At this point GDB will have "popped up" the source window to
display SOME_FUNCTION. Previously no window would have focus at this
point, and so if the user now does 'focus next' or 'focus prev', then
GDB would crash.
Calling tui_set_layout ensures that focus is correctly calculated as
the source window is "popped up", and this fixes the issue.

This removes the call to tui_show_source from tui_ui_out. This always
seemed like a hack, and now that the TUI is using the proper
observers, it seems not to be needed.
The rest of the logic remains, unfortunately, because it is needed to
suppress some gdb output in the TUI case. We could probably find a
nicer way to do this (maybe a ui_out_flag), but I haven't attempted
this.
This was the last caller of tui_show_source, so this is removed as
well.

PR tui/18932 notes that "list" no longer works in the TUI. At some
point in the past, it switched the TUI source window to show the
specified source; but now this source briefly flashes before the TUI
reverts to showing the current stack frame's source.
This patch fixes this bug by introducing a new observer that notices
when the user selected context has changed. Then, the existing
before-prompt observer is updated to request the correct update:
either one based on the current stack frame, or one based on the
user's source symtab_and_line.

tui_get_begin_asm_address looks for the inferior's "main" to display
it. I think this is incorrect in two ways.
First, it should probably instead use the user's most recent source
context, if one has been set.
Second, it uses a hard-coded list of "main" names, but gdb already has
a better approach to handling this.
