Subject: Fix MI output for multi-location breakpoints
... which mistakenly added NEWS entries in the "in gdb-8.3" section,
rather than in the "since gdb-8.3" one.
gdb/ChangeLog:
* NEWS: Move entries about default MI version now being
version 3, and about the GDB/MI fix for multi-location
breakpoints to the "since GDB 8.3" section.
For the lui and auipc relaxations, since the symbol value of an undefined weak
symbol is always be zero, we can optimize the patterns into a single LI/MV/ADDI
instruction.
bfd/
* elfnn-riscv.c (riscv_pcgp_hi_reloc): Add new field undefined_weak.
(riscv_record_pcgp_hi_reloc): New parameter undefined_weak.
Set undefined_weak field from it.
(relax_func_t): New parameter undefined_weak.
(_bfd_riscv_relax_call): New ignored parameter undefined_weak.
(_bfd_riscv_relax_tls_le): Likewise.
(_bfd_riscv_relax_align): Likewise.
(_bfd_riscv_relax_delete): Likewise.
(_bfd_riscv_relax_lui): New parameter undefined_weak. If true,
allow relaxing. For LO12* relocs, set rs1 to x0 when undefined_weak.
(_bfd_riscv_relax_pc): New parameter undefined_weak. For LO12* relocs,
set undefined_weak from hi_reloc. If true, allow relaxing. For LO12*
relocs, set rs1 to x0 when undefined_weak and change to non-pcrel
reloc.
(_bfd_riscv_relax_section): New local undefined_weak. Set for
undef weak relocs that can be relaxed. Pass to relax_func call.
ld/
* testsuite/ld-riscv-elf/weakref32.s: Add relaxable undef weak code.
* testsuite/ld-riscv-elf/weakref64.s: Likewise.
* testsuite/ld-riscv-elf/weakref32.d: Updated.
* testsuite/ld-riscv-elf/weakref64.d: Updated.
The TUI window-related commands like "focus" are case insensitive.
This is not the norm in gdb, and I don't see a good reason to have it
here. This patch changes the TUI to be case sensitive, like the rest
of gdb.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* NEWS: Mention case-sensitivity of TUI commands.
* tui/tui-win.c (tui_set_focus_command): Now case-sensitive.
(tui_set_win_height_command, parse_scrolling_args): Likewise.
* tui/tui-layout.c (tui_layout_command): Now case-sensitive.
This changes a couple of spots in the TUI to use make_unique_xstrdup.
This simplifies the code slightly.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-source.c (tui_source_window::set_contents): Use
make_unique_xstrdup.
* tui/tui-disasm.c (tui_disasm_window::set_contents): Use
make_unique_xstrdup.
This removes various separator comments from the TUI. These aren't
used elsewhere in gdb, and they were incorrect in some cases as well.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>

An earlier patch in the series removed the last call to strcat_to_buf,

* tui/tui-source.c (tui_source_window::set_contents)
(tui_source_window::location_matches_p)
(tui_source_window::maybe_update): Update.
As Pedro suggested, this patch renames the private data members of
tui_data_window to use the "m_" prefix.

(tui_data_window::erase_data_content)
(tui_data_window::do_scroll_vertical)
(tui_data_window::refresh_window)
(tui_data_window::check_register_values): Update.
This changes two members of tui_locator_window to have type
std::string. This removes a static limit.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-stack.h (MAX_LOCATOR_ELEMENT_LEN): Remove define.
(struct tui_locator_window) <full_name, proc_name>: Now
std::string.
* tui/tui-stack.c (tui_locator_window::make_status_line)
(tui_locator_window::set_locator_fullname)
(tui_locator_window::set_locator_info): Update.
* tui/tui-source.c (tui_source_window::set_contents)
(tui_source_window::showing_source_p): Update.
Commit e594a5d1 ("Turn two locator functions into methods") turned
set_locator_fullname into a method on tui_locator_window. I missed it
at the time, but this change allows for the removal of a call to
tui_locator_win_info_ptr.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-stack.c (tui_locator_window::set_locator_fullname):
Don't call tui_locator_win_info_ptr.
There's no reason to call refresh in tui_resize_all. This call
flushes the curses window contents to the terminal -- but, because
we're about the resize all the windows, we're going to be sending more
data to the terminal momentarily. This patch removes the call.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-win.c (tui_resize_all): Don't call refresh.
The TUI has long had code to resize the locator, using 2 as the
height. However the code has "1" in a comment, like:
locator->resize (2 /* 1 */ ,
This patch fixes the resizing code to set the height to 1. Doing this
revealed what was probably the reason for setting the height to 2 in
the first place: this caused the locator window to scroll. However,
this is easily handled by calling scrollok on the locator window.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-win.c (tui_resize_all, tui_adjust_win_heights): Use 1 as
height for locator.
* tui/tui-stack.c (tui_locator_window::rerender): Call scrollok.
* tui/tui-layout.c (show_source_disasm_command, show_data)
(show_source_or_disasm_and_command): Use 1 as height for locator.
This changes the "win_resized" global to be a bool and then updates
the uses.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui.c (tui_enable): Update.
* tui/tui-win.c (tui_sigwinch_handler, tui_async_resize_screen):
Update.
* tui/tui-data.h (tui_win_resized, tui_set_win_resized_to):
Update.
* tui/tui-data.c (win_resized): Now bool.
(tui_win_resized): Return bool.
(tui_set_win_resized_to): Accept a bool.
This changes tui_data_window::show_register_group to use "bool" rather
than "int".
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-regs.h (struct tui_data_window) <show_register_group>:
Change type of "refresh_values_only".
* tui/tui-regs.c (tui_data_window::show_register_group): Change
type of "refresh_values_only".
tui_source_window_base::show_source_content is not used outside the
class any more, so this makes it private. Examining the callers shows
that it can't be called without source contents, so it can be
simplified as well.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-winsource.h (struct tui_source_window_base)
<show_source_content>: Now private.
* tui/tui-winsource.c
(tui_source_window_base::show_source_content): Don't handle empty
content case.
A couple of spots in tui-layout.c still call the show_source_content
method. However, now that re-rendering is done by the resize method,
these calls are no longer needed.
gdb/ChangeLog
2019-09-20 Tom Tromey <tom@tromey.com>
* tui/tui-layout.c (show_source_disasm_command)
(show_source_or_disasm_and_command): Don't call
show_source_content.
This changes tui_make_status_line to be a method on
tui_locator_window. This is a minor cleanup.
This also changes the new method to use the locator's width, rather
than the terminal width. This is important if we ever want to allow
windows to be made more narrow.

* tui/tui-stack.c (tui_locator_window::make_status_line): Rename

(tui_locator_window::rerender): Update.
This changes tui_make_status_line to return std::string. This cleans
it up a bit, and removes some explicit memory management.

to be a unique_xmalloc_ptr.

The calls to tui_clear_source_windows_detail in tui_add_win_to_layout
aren't needed, because (after the resize unification) resizing will
update the window contents. Removing these calls lets us remove
several other things as well.

If gdb_test is used with fewer than five arguments, then the question_string

if [llength $args]==5 {
set question_string [lindex $args 3]

} else {

This can however match "FOOBAR", so perhaps "\$FOOBAR^" would have been a
better choice.

Currently in source_cache::ensure we catch the exception that triggers when
highlighter->highlight is called:
...
try

std::ostringstream output;
highlighter->highlight (input, output, lang_name, fullname);
...
and the file used earlier in the construction of the highlighter:
...
highlighter = new srchilite::SourceHighlight ("esc.outlang");
...
is missing.
The fact that this exception triggers when highlighter->highlight is called is
an implementation artefact of libsource-highlight.so though, and this could be
different for older or newer versions.
Make things more robust by also catching exceptions thrown during construction
of the highlighter. This makes the handling on master equivalent with what

commit 677052f2a5
Author: Sergio Durigan Junior <sergiodj@redhat.com>
Date: Thu May 16 16:23:24 2019 -0400
Subject: Make stap-probe.c:stap_parse_register_operand's "regname"
an std::string
Readline 8.0 has a feature that lets an application name a keymap.
This in turn makes it simpler for users to bind keys in keymaps in
their .inputrc.
This patch gives a name to the TUI SingleKey keymap, so that
additional bindings can be made there. For example:
$if gdb
set keymap SingleKey
"X": "echo hello\\n\n"
$endif
The call to rl_initialize, in tui_initialize_readline, had to be
removed so that .inputrc was not read too early. Note that Readline
explicitly documents that this call is not needed.

0x55555b25d441 is located 0 bytes to the right of global variable 'cli_styling' defined in '/home/simark/src/binutils-gdb/gdb/cli/cli-style.c:31:6' (0x55555b25d440) of size 1
The reason of this is that we have this declaration of cli_styling in cli/cli-style.h:
extern bool cli_styling;
but ui-file.c uses its own local declaration:
extern int cli_styling;
Because of that, the code in ui-file.c thinks the variable is 4 bytes
long, when it is actually 1 byte long, so the generated code reads past
the variable.
Fix it by removing the declaration and making ui-file.c include
cli/cli-style.h.
gdb/ChangeLog:
* ui-file.c: Include cli/cli-style.h.
(term_cli_styling): Remove cli_styling declaration.
Give a test an actual name in order to avoid having a directory name
in the .sum file.
gdb/testsuite/ChangeLog:
* gdb.base/source-dir.exp: Avoid having directory names in test
names.
