PR gdb/28155 notes a crash in "finish" that occurs with a particular
source file compiled by clang.
The bug is the typical gdb problem of a missing call to check_typedef.
clang emits a function whose return type is a typedef to void.
get_return_value asserts that the return type is not void, but the
callers were not using check_typedef first.

[Inferior 1 (process 684960) exited normally]
(gdb) run
Segmentation fault
The crash happens while processing the CREATE_PROCESS_DEBUG_EVENT
for the second run; in particular, we have in get_windows_debug_event:
| case CREATE_PROCESS_DEBUG_EVENT:
| [...]
| if (main_thread_id)
| windows_delete_thread (ptid_t (current_event.dwProcessId, 0,
| main_thread_id),
| 0);
The problem is that main_thread_id is the TID of the main thread from
the *previous* inferior, and this code is trying to delete that
thread. The problem is that it is constructing a PTID by pairing
the TID of the previous inferior with the PID of the new inferior.
As a result, when we dig inside windows_delete_thread to see
how it would handle that, we see...
| delete_thread (find_thread_ptid (ptid));
Since the PTID is bogus, we end up calling delete_thread with
a NULL thread_info. It used to be harmless, turning the delete_thread
into a nop, but the following change...
| commit 080363310650c93ad8e93018bcb6760ba5d32d1c
| Date: Thu Nov 22 16:09:14 2018 +0000
| Subject: Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.
... changed delete_thread to get the list of threads from
the inferior, which itself is now accessed via the given
thread_info. This is the corresponding diff that shows the change:
| - for (tp = thread_list; tp; tpprev = tp, tp = tp->next)
| + for (tp = thr->inf->thread_list; tp; tpprev = tp, tp = tp->next)
As a result of this, passing a NULL thread_info is no longer
an option!
Stepping back a bit, the reason behind deleting the thread late
could be found in a patch from Dec 2003, which laconically explains:
| commit 87a45c96062d658ca83b50aa060a648bf5f5f1ff
| Date: Fri Dec 26 00:39:04 2003 +0000
|
| * win32-nat.c (get_child_debug_event): Keep main thread id around
| even after thread exits since Windows insists on continuing to
| report events against it.
A look at the gdb-patches archives did not provide any additional
clues (https://www.sourceware.org/ml/gdb-patches/2003-12/msg00478.html).
It is not clear whether this is still needed or not. This patch
assumes that whatever isue there was, the versions of Windows
we currently support no longer have it.
With that in mind, this commit fixes the issue by deleting the thread
when the inferior sends the exit-process event as opposed to deleting it
later, while starting a new inferior.
This also restores the printing of the thread-exit notification for
the main thread, which was missing before. Looking at the transcript
of the example shown above, we can see 4 thread creation notifications,
and only 3 notifications for thread exits. Now creation and exit
notifications are balanced.
In the handling of EXIT_THREAD_DEBUG_EVENT, the main_thread_id
check is removed because deemed unnecessary: The main thread was
introduced by a CREATE_PROCESS_DEBUG_EVENT, and thus the kernel
is expected to report its death via EXIT_PROCESS_DEBUG_EVENT.
And finally, because the behavior of delete_thread did change
(albeit when getting a value we probably never expected to receive),
this patch also adds a gdb_assert. The purpose is to provide some
immediate information in case there are other callers that mistakenly
call delete_thread with a NULL thread info. This can be useful
information when direct debugging of GDB isn't an option.
gdb/ChangeLog:
* thread.c (delete_thread_1): Add gdb_assert that THR is not
NULL. Initialize tpprev to NULL instead of assigning it
to NULL on the next statement.
* windows-nat.c (windows_delete_thread): Remove check for
main_thread_id before printing thread exit notifications.

valgrind pointed out that the string copy in tui_set_source_content
was not allocating space for the trailing \0:
==3941== Invalid write of size 1
==3941== at 0x4C3239F: strcpy (vg_replace_strmem.c:512)
==3941== by 0x72036B: strcpy (string_fortified.h:90)
==3941== by 0x72036B: tui_set_source_content(symtab*, int, int) (tui-source.c:203)
Looking closer, I don't think there's a need to check the line width
here, so this patch changes it to use xstrdup.
Tested by re-running the TUI under valgrind. There are still other
valgrind reports from TUI code, but this one is gone.

This introduces a new class that wraps PyErr_Fetch and PyErr_Restore,
and then changes all the callers in gdb to use it. This reduces the

This patch moves the per-inferior data related to displaced stepping to
be directly in the inferior structure, rather than in a container on the
side.
On notable difference is that previously, we deleted the state on
inferior exit, which guaranteed a clean state if re-using the inferior
for a new run or attach. We now need to reset the state manually.
At the same time, I changed step_saved_copy to be a gdb::byte_vector, so
it is automatically freed on destruction (which should plug the leak
reported here [1]).

When using remote debugging server, and when debuggee filename is
inferred via qXfer:exec-file:read request, or sysroot starts with
"target:", this "target:" prefix of filepaths is not treated correctly
during debug file search - it appears in the middle of the looked up
paths.
In the following example, unpatched GDB can't find separate debug files for

The year range in the copyright header of that file was incorrect:
// Copyright (C) 3 Free Software Foundation, Inc.
Tracing the origin of this file down, I found that it was copied
from GCC's libstdc++-v3 testsuite:
Adapt and integrate string_view tests
https://www.sourceware.org/ml/gdb-patches/2018-04/msg00113.html
Looking at the version in GCC, I found the same issue, so sent
a fix there:
https://gcc.gnu.org/ml/gcc-patches/2019-01/msg00000.html
Now that the fix is in GCC, this commit applies the same fix
to our copy.

The goal of this commit is to allow RV64 binaries compiled for the 'F'
extension to run on a target that supports both the 'F' and 'D'
extensions.
The 'D' extension depends on the 'F' extension and chapter 9 of the
RISC-V ISA manual implies that running a program compiled for 'F' on
a 'D' target should be fine.
To support this the gdbarch now holds two feature sets, one represents
the features that are present on the target, and one represents the
features requested in the ELF flags.
The existing error checks are relaxed slightly to allow binaries
compiled for 32-bit 'F' extension to run on targets with the 64-bit
'D' extension.
A new set of functions called riscv_abi_{xlen,flen} are added to
compliment the existing riscv_isa_{xlen,flen}, and some callers to the
isa functions now call the abi functions when that is appropriate.
In riscv_call_arg_struct two asserts are removed, these asserts no
longer make sense. The asserts were both like this:
gdb_assert (TYPE_LENGTH (ainfo->type)
<= (cinfo->flen + cinfo->xlen));
And were made in two cases, when passing structures like these:
struct {
integer field1;
float field2;
};
or,
struct {
float field1;
integer field2;
};
When running on an RV64 target which only has 32-bit float then the
integer field could be 64-bits, while if the float field is 32-bits
the overall size of the structure can be 128-bits (with 32-bits of
padding). In this case the assertion would fail, however, the code
isn't incorrect, so its safe to just remove the assertion.
This was tested by running on an RV64IMFDC target using a compiler
configured for RV64IMFC, and comparing the results with those obtained
when using a compiler configured for RV64IMFDC. The only regressions
I see (now) are in gdb.base/store.exp and are related too different
code generation choices GCC makes between the two targets.
Finally, this commit does not make any attempt to support running
binaries compiled for RV32 on an RV64 target, though nothing in here
should prevent that being supported in the future.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

The layout for 'help set address|variable' is strange, e.g.:
(gdb) help set style address
style address
List of show Address display styling
Configure address colors and display intensity subcommands:
show Address display styling
Configure address colors and display intensity background -- Set the background color for this property
show Address display styling
Configure address colors and display intensity foreground -- Set the foreground color for this property
show Address display styling
Configure address colors and display intensity intensity -- Set the display intensity color for this property
Type "help show Address display styling
Configure address colors and display intensity" followed by show Address display styling
Configure address colors and display intensity subcommand name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.
(gdb)
The help for 'set style function|filename' gives help for 'Show':
(gdb) help set style filename
Filename display styling
Configure filename colors and display intensity.
List of show style filename subcommands:
show style filename background -- Set the background color for this property
show style filename foreground -- Set the foreground color for this property
show style filename intensity -- Set the display intensity color for this property
The help for 'show style function|filename' is equally strange, as it speaks
about commands, instead of sub commands:
(gdb) help show style filename
Filename display styling
Configure filename colors and display intensity.
List of commands:
background -- Show the background color for this property
foreground -- Show the foreground color for this property
intensity -- Show the display intensity color for this property
Type "help" followed by command name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.
(gdb)
This patch fixes all this.
Note that the 'set style' and 'show style' have the same prefix_doc:
(gdb) help show style
Style-specific settings
Configure various style-related variables, such as colors
...
(gdb) help set style
Style-specific settings
Configure various style-related variables, such as colors
...
Other similar commands (such as set|show history) have typically
a more specific prefix:
(gdb) help show history
Generic command for showing command history parameters.
...
(gdb) help set history
Generic command for setting command history parameters.
...
This could be fixed by having set_prefix_doc and show_prefix_doc instead of
the single prefix_doc argument to cli_style_option::add_setshow_commands.
That could be improved if deemed better.
2018-12-29 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* cli/cli-style.c (cli_style_option::add_setshow_commands):
Initialize m_set_prefix with "set", instead of re-assigning

variable_name_style.add_setshow_commands and
address_style.add_setshow_commands calls.

PR tui/14126 notes that ANSI terminal escape sequences don't affect
the colors shown in the TUI. A simple way to see this is to try the
extended-prompt example from the gdb manual.
Curses does not pass escape sequences through to the terminal.
Instead, it replaces non-printable characters with a visible
representation, for example "^[" for the ESC character.
This patch fixes the problem by adding a simple ANSI terminal sequence
parser to gdb. These sequences are decoded and those that are
recognized are turned into the appropriate curses calls.
The curses approach to color handling is unusual and so there are some
oddities in the implementation.
Standard curses has no notion of the default colors of the terminal.
So, if you set the foreground color, it is not possible to reset it --
you have to pick some other color. ncurses provides an extension to
handle this, so this patch updates configure and uses it when
available.
Second, in curses, colors always come in pairs: you cannot set just
the foreground. This patch handles this by tracking actually-used
pairs of colors and keeping a table of these for reuse.
Third, there are a limited number of such pairs available. In this
patch, if you try to use too many color combinations, gdb will just
ignore some color changes.
Finally, in addition to limiting the number of color pairs, curses
also limits the number of colors. This means that, when using
extended 8- or 24-bit color sequences, it may be possible to exhaust
the curses color table.
I am very sour on the curses design now.
I do not know how to write a test for this, so I did not.

This adds style support for variable names. For the time being, this
is only done in backtraces, not in ptype or print; those places do not
use ui-out and so would need ad hoc changes.
This also adds styling to the names printed for local variables in
"backtrace full". This code does not use ui-out, so the styling is
done using the low-level API.

This adds a function that can be used to reset terminal styles,
regardless of what style the low-level output routines currently think
is applied.
This is used to make "echo" and "printf" work properly when emitting
ANSI terminal escapes -- now gdb will reset the style at the end of
the command.
