Turning various calls into methods has made it possible to now change
some tui_data_window methods to be private.
2019-08-20 Tom Tromey <tom@tromey.com>
* tui/tui-regs.h (struct tui_data_window) <last_regs_line_no,
line_from_reg_element_no, first_reg_element_no_inline,
display_all_data, delete_data_content_windows,
erase_data_content>: Now private.

This removes the HILITE and NO_HILITE defines from tui-data.h, in
favor of simply passing a bool to box_win.
2019-08-20 Tom Tromey <tom@tromey.com>
* tui/tui-wingeneral.c (box_win): Change type of highlight_flag.
(tui_unhighlight_win, tui_highlight_win)
(tui_win_info::make_window): Update.
* tui/tui-data.h (HILITE, NO_HILITE): Remove.

Some #defines in tui-data.h are only used in tui-stack.c, so move them
there.
2019-08-20 Tom Tromey <tom@tromey.com>
* tui/tui-data.h (PROC_PREFIX, LINE_PREFIX, PC_PREFIX)
(MIN_LINE_WIDTH, MIN_PROC_WIDTH, MAX_TARGET_WIDTH)
(MAX_PID_WIDTH): Move to tui-stack.c.
* tui/tui-stack.c (PROC_PREFIX, LINE_PREFIX, PC_PREFIX)
(MIN_LINE_WIDTH, MIN_PROC_WIDTH, MAX_TARGET_WIDTH)
(MAX_PID_WIDTH): Move from tui-data.h.

I combined several small changes into one patch here. I believe I
started by noticing that the "title" is not needed by tui_gen_win_info
and could be self-managing (i.e. std::string). Moving this revealed
that "can_box" is also a property of tui_win_info and not
tui_gen_win_info; and this in turn caused the changes to
tui_make_window and box_win.
2019-08-20 Tom Tromey <tom@tromey.com>
* tui/tui-wingeneral.h (tui_make_window): Don't declare.

There's no need for tui_data_window::display_regs any more (if there
ever was). All the paths through data window construction will end up
setting this to true. This patch removes the member.

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.

This changes tui_check_register_values to be a method on
tui_data_window. An additional check in tui_register_changed is

This moves tui_reg_layout later in tui-regs.c, closer to where it is
used.
It also changes tui_show_registers not to enable the TUI or change the
layout -- this is already done by this point by all the callers.

* tui/tui-regs.c (tui_reg_layout): Move later.
(tui_show_registers): Don't enable TUI mode or change layout.

This changes tui_data_item_window::content to be a unique_xmalloc_ptr
and fixes up the fallout. It also removes a parameter from
tui_expand_tabs, as it was only ever given one value.
This also removes some tab-handling code from
tui_data_window::display_registers_from. Because the content can only
be set by tui_register_format, and because that calls tui_expand_tabs,
it's not possible to see a tab here.

The TUI has a few #defines that hold user-visible strings. As these
are only used in a single spot, this patch removes the defines,
preferring direct use of the string where needed. Furthermore, now
the strings are wrapped in _(), which is friendlier for i18n purposes.

We currently use a padding NOP after a Thumb to Arm interworking veneer (BX pc).
The NOP is never executed but may result in a performance penalty on some cores.

When running a pascal test with the stabs target board:
...
$ test=gdb.pascal/case-insensitive-symbols.exp
$ cd build/gdb/testsuite
$ make check RUNTESTFLAGS="$test --target_board=stabs"
...
we get:
...
nr of untested testcases 1
nr of unsupported tests 1
...
due to:
...
Error: Illegal parameter: -gstabs+^M
Error: /usr/bin/ppcx64 returned an error exitcode^M
...
OTOH, when running the same pascal test without the stabs target board:
...
$ make check RUNTESTFLAGS="$test"
...
we get:
...
nr of expected passes 20
...
But when subsequently again running with the stabs target board:
...
$ make check RUNTESTFLAGS="$test --target_board=stabs"
...
we now get:
...
nr of expected passes 20
...
The problem is that gdb_compile_pascal determines success based on existence
of the exec after compilation:
...
if ![file exists $destfile] {
unsupported "Pascal compilation failed: $result"
return "Pascal compilation failed."
}
...
without removing the exec before compilation, which allows a stale exec to
make it seem as if compilation has succeeded.
Fix this by removing the stale exec before compilation.

For remotes which do not support btrace at all, we can save several
round trips for each thread. This is especially significant when your
remote is a kernel with 100s or 1000s of threads and latency is
intercontinental.
Previously, with target, remote, and infrun debugging enabled, one
might see:
Sending packet: $Hg18aee#43...Ack
Packet received: OK
Sending packet: $Hg186f7#eb...Ack
Packet received: OK
remote:target_xfer_partial (24, , 0x805454000, 0x0, 0x0, 4096) = -1, 0
repeated for all non-exited threads.
Afterwards, if the remote does not specify 'qXfer:btrace-conf:read+'
in qSupported stub features, these unnecessary thread switches are
avoided.

* remote.c (remote_target::remote_btrace_maybe_reopen): Avoid
unnecessary thread walk if remote doesn't support the packet.

Sergio pointed out that commit commit aa3b6533 ("Allow nested function
displays") regressed a few gdb.fortran tests. I was able to reproduce
these failures with gcc head.
The bug is that some spots calling contained_in will in fact do the
wrong thing if nested functions are considered as contained. In the
particular case of the Fortran regression, it was the call in
block_innermost_frame, being called from get_hosting_frame -- in this
case, the caller is specifically trying to avoid the nested case.
This patch fixes the problem by adding an "allow_nested" parameter to
contained_in, essentially reverting the change for most callers.

Currently, no release of GNU Source Highlight supports Rust. However,
I've checked in a patch to do so there, and I plan to make a new
release sometime this summer.
This patch prepares gdb for that by adding support for Rust to the
source highlighting code.
Because Source Highlight will throw an exception if the language is
unrecognized, this also changes gdb to ignore exceptions here. This
will cause gdb to fall back to un-highlighted source text.
This updates gdb's configure script to reject the combination of
Source Highlight and -static-libstdc++. This is done because it's not
possible to use -static-libstdc++ and then catch exceptions from a
shared library.
Tested with the current and development versions of Source Highlight.

gdb should normally not be linked with -static-libstdc++. Currently
this has not caused problems, but it's incompatible with catching an
exception thrown from a shared library -- and a subsequent patch
changes gdb to do just this.
This patch adds a new --with-static-standard-libraries flag to the
top-level configure. It defaults to "auto", which means enabled if
gcc is being built, and disabled otherwise.

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.

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.

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.

Add a new print_pc which prints both the PC and a new field addr_flags.
Call this wherever the PC is printed in stack.c.
Add a new gdbarch method get_pc_address_flags to obtain the addr_flag
contents. By default returns an empty string, on AArch64 this returns
PAC if the address has been masked in the frame.
Document this in the manual and NEWS file.

* NEWS (Other MI changes): New subsection.
* aarch64-tdep.c (aarch64_get_pc_address_flags): New function.
