If the RISC-V prologue scanner finds a 6 or 8 byte instruction we
currently throw an internal error, which is not great for the user.
A mechanism already exists in the prologue scanner to leave
instructions marked as unknown so that we can stop the prologue scan
without raising an error, this is used for all 2 and 4 byte
instructions that are not part of the small set the prologue scanner
actually understands.
This commit changes GDB so that all 6 and 8 byte instructions are
marked as unknown, rather than causing an error.

Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

Factorizes the testing of the help output, by having a single place
that defines the common help trailer and/or prefix messages.
|
|
The "help" command can output long list of command names or classes.
Use the title style to style the command names or classes to make
the output more readable.
Similarly, change "apropos" command to also style the command names.
It is sometimes unclear why "apropos REGEXP" lists some commands,
and then the user has to manually do 'help command' for all commands
listed by "apropos" to see more details about the matching commands.
=> Add an optional flag -v so that "apropos -v REGEXP":
* outputs the full documentation of matching commands.
* highlights the documentation parts matching REGEXP.
|

Have 'show style' and its subcommands using a style to style its output.
This allows the GDB user or developer to use 'show style' to visually see
with one command how all the current styles look like.
Add 2 new styles highlight style, title style and fputs_highlighted function.
Highlight style is used by fputs_highlighted to highlight the parts of
its char *STR argument that match a HIGHLIGHT regexp.
This (and the title style) will be used in a following patch.

The pipe command allows to run a GDB command, and pipe its output
to a shell command:
(gdb) help pipe
Send the output of a gdb command to a shell command.
Usage: | [COMMAND] | SHELL_COMMAND
Usage: | -d DELIM COMMAND DELIM SHELL_COMMAND
Usage: pipe [COMMAND] | SHELL_COMMAND
Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND
Executes COMMAND and sends its output to SHELL_COMMAND.
The -d option indicates to use the string DELIM to separate COMMAND
from SHELL_COMMAND, in alternative to |. This is useful in
case COMMAND contains a | character.
With no COMMAND, repeat the last executed command
and send its output to SHELL_COMMAND.
(gdb)
For example:
(gdb) pipe print some_data_structure | grep -B3 -A3 something
The pipe character is defined as an alias for pipe command, so that
the above can be typed as:
(gdb) | print some_data_structure | grep -B3 -A3 something
If no GDB COMMAND is given, then the previous command is relaunched,
and its output is sent to the given SHELL_COMMAND.
This also defines convenience vars $_shell_exitcode and $_shell_exitsignal
to record the exit code and exit signal of the last shell command
launched by GDB e.g. by "shell", "pipe", ...

Currently, a previous command can be repeated when the user types an
empty line. This is implemented in handle_line_of_input by
returning saved_command_line in case an empty line has been input.
If we want a command to repeat the previous command, we need to save
the previous saved_command_line, as when a command runs, the saved_command_line
already contains the current command line of the command being executed.
As suggested by Tom, the previous_saved_command_line is made static.
At the same time, saved_command_line is also made static.
The support functions/variables for the repeat command logic are now all
located inside top.c.

Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1715008
On commit 7bede82892a06e6c26989803e70f53697392dcf9 ("Don't crash if
dwarf_decode_macro_bytes's 'body' is NULL"), I was too strict when
checking if 'body' is NULL: the check only comprised the case when
'is_define' is true. However, the corruption of .debug_macro by
rpmbuild's "debugedit" also affects the case when 'is_define' is
false, i.e., when the macro is being undefined.
This commit improves the check and covers both cases now. This has
been tested on Fedora 30 with a problematic debuginfo, and I don't see
a segfault anymore.
OK to push?

PR c++/20020 concerns a crash in cp_print_value_fields. The immediate
cause is that cp_print_value_fields does not handle the case where
value_static_field fails. This is fixed in this patch by calling
cp_print_static_field from the "try" block.
Digging a bit deeper, the error occurs because GCC does not emit a
DW_AT_const_value for a static constexpr member appearing in a
template class. I've filed a GCC bug for this.

A user wanted to be able to disable the display of the value when
using "finish" -- but still have the value entered into the value

We found a case where a "bt" was very slow with Ada code. Profiling
with callgrind showed this to be primarily due to calls to
find_old_style_renaming_symbol. Because new-style renaming symbols
were implemented in 2007, it seems safe enough to remove this old
code.
A "-batch -ex bt" test on a large Ada program improves from:
13.23user 0.57system 0:13.82elapsed 99%CPU (0avgtext+0avgdata 571408maxresident)k

This solves an assertion failure when a remote provides a target
description which only refers to floating point registers by their
hardware name (e.g. f0), rather than their ABI name (e.g. ft0). GDB

it would contain a register called ft0.
The floating point length is now instead determined by searching for

commit 34d11c682fd96c7dbe3ebd6cd9033e65d51ec7a3
Date: Fri May 3 15:23:55 2019 +0100
gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
GDB was changed such that the Fortran's 16-byte float format was
obtained by calling gdbarch_floatformat_for_type instead of just using
gdbarch_long_double_format as it was before.
The problem with this default_floatformat_for_type can return NULL in
some cases, and the code introduced in 34d11c682f didn't consider
this.
This commit introduces several alternative strategies for finding a
suitable 16-byte floating point type. First GDB calls
gdbarch_floatformat_for_type (this was what 34d11c682f added), if this
returns null GDB will use gdbarch_long_double_format if it is the
correct size (this was the format used before 34d11c682f). Finally,
if neither of the above provides a suitable type then GDB will create
a new dummy type.
This final dummy type is unlikely to provide an correct debug
experience as far as examining the 16-byte floats, but it should
prevent GDB crashing.

* f-lang.c (build_fortran_types): Handle the case where
gdbarch_floatformat_for_type returns a nullptr.

PR gdb/18644 is caused by GDB using the wrong floating point format
for gfortran's 16-byte floating point type, including when the 16-byte
float is used as the component of a 32-byte complex type.
This commit addresses the issue in two places, first in i386-tdep.c,
there is already some code to force the use of floatformats_ia64_quad
for specific named types, this is extended to include the type names
that gfortran uses for its 16-byte floats.
Second, the builtin 16-byte float type (in f-lang.c) is changed so it
no longer uses gdbarch_long_double_format. On i386 this type is not
16-bytes, but is smaller, this is not what gfortran is expecting.
Instead we now use gdbarch_floatformat_for_type and ask for a
16-byte (128 bit) type using the common gfortran type name. This is
then spotted in i386-tdep.c (thanks to the first change above) and we
again get floatformats_ia64_quad returned.
This patch was tested on X86-64/GNU-Linux using '--target_board=unix'
and '--target_board=unix/-m32', and resolves all of the known failures
associated with PR gdb/18644. I've also added the test case from the
original bug report.

Adds a constructor to 'struct cu_partial_die_info' and disables the
default constructor, preventing partially initialised instances from
being created.
Update 'find_partial_die' to return a const struct.
Users of 'find_partial_die' are updated to take account of the above
two changes.
There should be no user visible changes after this commit.

* dwarf2read.c (struct cu_partial_die_info): Add constructor,
delete default constructor.
(find_partial_die): Update to return const struct.
(partial_die_parent_scope): Move variable declaration into scope
of its use and change its type to auto.

find_and_open_source casts away const, but hasn't needed to in a

Add "replay" to the list of GDBSERVER_DEBUG options. This will
cause a gdbserver.replay file to be written to the test output
directory.
At the same time switch this to a comma separated list in order
to easily handle all possible options.
The replay log is created by GDB, but has been added to
GDBSERVER_DEBUG as it is only required for gdbserver tests. To
enable it, the gdb_debug_init is overridden to allow the additional
checking, before calling the original function.
gdb/testsuite/ChangeLog:
* README (Testsuite Parameters): Add replay logging to
GDBSERVER_DEBUG.
(gdbserver,debug): Refer to GDBSERVER_DEBUG.
* lib/gdbserver-support.exp (gdbserver_start): Treat gdbserverdebug
as a comma separated list.
(gdb_debug_init): Override procedure.

When debugging testsuite failures, it can be awkward parsing gdb.log to
obtain all the commands run in order to manually re-run the test.
This patch adds the functionality to save all gdb commands to the file gdb.in
when the testsuite is run. The file is saved in the directory for the test and
if gdb is restarted then .1, .2, .3 etc is added to the filename.
Once a test has been run, the .in file can be used to re-run the test in the
following way:
gdb -x outputs/gdb.store/gdb.in outputs/gdb.store/store
The code works by intercepting send_gdb. I've added a TYPE to ensure that any
commands that would destroy the playback are kept from the log (for example the
Y from an answer to a y/n question).
Adds library function standard_output_file_with_gdb_instance to open a file
postfixed with count of the gdb instance. Ensure this count is reset when a new
.exp script is run.
I've re-run a random selection of .in files to check they do not error. Logs with
commands such as "attach <pid>" will not directly work when re-run.

Fix up all failures encountered when running the testsuite with
GDB_DEBUG="infrun".
Some tests rely on enabling debugging for various components. With
debugging on, this will be lost to the debug file.
Disable separate tty for mi tests when debugging. This currently
does not work.
disasm.c should send errors to the stderr instead of the logfile.
Note that enabling debug for other components might still cause
additional errors above what has been fixed here.

* disasm.c (set_disassembler_options): Send errors to stderr.

Add both board option and environment variable which enables gdb
debug via a comma separated list and sends it to the file gdb.debug,
located in the output directory for the current test. Document this.
Add support for the environment variable in the Makefile.
The testsuite can be run with gdb debug enabled in the following way:
make check GDB_DEBUG="infrun,target,remote"
A Test with multiple invocations of GDB will all append debug to the
same log file.
gdb/testsuite/ChangeLog:
* Makefile.in: Pass through GDB_DEBUG.
* README (Testsuite Parameters): Add GDB_DEBUG.
(gdb,debug): Add board setting.
* lib/gdb.exp (default_gdb_start): Start debugging.
(gdb_debug_enabled): New procedure.
(gdb_debug_init): Likewise.

Currently, when logging is enabled, output will be sent to both a
logfile and standard terminal output. The redirect option sends output
only to the logfile. This includes all debug output.
Add the option to redirect debug output seperately to normal
output, using the cli command:
set logging debugredirect on
By setting this and enabling logging, all output and debug will
be sent to the logfile. The user will still see all output but
no debug output.
This causes a change in behaviour for anyone currently using
logging redirect, as now only output will be redirected. Users
will have to issue the additional command above to also redirect
debug.
Expand ui-redirect.exp cover the changes.
gdb/ChangeLog:
* cli/cli-interp.c (struct saved_output_files): Add saved entry.
(cli_interp_base::set_logging): Check debug_redirect.
* cli/cli-interp.h (set_logging): Add debug_redirect parameter.
* cli/cli-logging.c (debug_redirect): Add static variable.

* interps.c (current_interp_set_logging): Add debug_redirect
parameter.

Instead of using two bools to decide if the files should close when tee_file
is closed, make file one stay open and file two close. This simplifies the
use cases for it.
Inline the make_logging_output into the calling functions (the logic here
looks ugly in order to simplify a later change).
Expand ui-redirect.exp to cover the changes, similar to mi-logging.exp.
gdb/ChangeLog:
* cli/cli-interp.c (cli_interp_base::set_logging): Create tee_file
directly.
* cli/cli-interp.h (make_logging_output): Remove declaration.
* cli/cli-logging.c (make_logging_output): Remove function.
* mi/mi-interp.c (mi_interp::set_logging): Create tee_file
