The 'frame' command is documented in two places. The 'select-frame'
command is only mentioned in one of these places.
Of the two places, having the description of 'frame' and 'select-frame'
in the section 'Selecting a Frame' seems like the most obvious choice,
which is where things like 'up' and 'down' are also documented.
This commit moves the documentation of 'frame' and 'select-frame' into
the 'Selecting a Frame' section, and removes the duplicate documentation
of the 'frame' command.
At the same time I have reordered the sections in the 'Examining the
Stack' chapter, moving the discussion of frame filters to the end of the
chapter; it feels odd that we talk about frame filters before such basic
things like navigating the stack, or examining stack frames in general.
gdb/doc/ChangeLog:
* gdb.texinfo (Frames): Remove 'frame' and 'select-frame'
description.
(Frame Filter Management): Move to later in the 'Examining the
Stack' chapter.
(Selection): Add entry for 'select-frame'.

Record targets behave as if scheduler-locking were on in replay mode. Add a
new scheduler-locking option "replay" to make this implicit behaviour explicit.
It behaves like "on" in replay mode and like "off" in record mode.
By making the current behaviour a scheduler-locking option, we allow the user
to change it. Since it is the current behaviour, this new option is also
the new default.
One caveat is that when resuming a thread that is at the end of its execution
history, record btrace implicitly stops replaying other threads and resumes
the entire process. This is a convenience feature to not require the user
to explicitly move all other threads to the end of their execution histories
before being able to resume the process.
We mimick this behaviour with scheduler-locking replay and move it from
record-btrace into infrun. With all-stop on top of non-stop, we can't do
this in record-btrace anymore.
Record full does not really support multi-threading and is therefore not
impacted. If it were extended to support multi-threading, it would 'benefit'
from this change. The good thing is that all record targets will behave the
same with respect to scheduler-locking.
I put the code for this into clear_proceed_status. It also sends the
about_to_proceed notification.

The previous manual change was wrong. The vfork parent thread ID
should be reported with the usual "thread" magic register:
Sending packet: $vCont;c:p7260.7260#1e...Packet received: OK
- Notification received: Stop:T05vforkdone:;
+ Notification received: Stop:T05vforkdone:;thread:p7260.7260
^^^^^^^^^^^^^^^^^
This is already how the parent is reported in the vfork/fork events,
and is actually what the fix made gdbserver do. Following the
documentation change, the event would have been reported like this
instead:
Notification received: Stop:T05vforkdone:p7260.7260

The vforkdone stop reply misses indicating the thread ID of the vfork
parent which the event relates to:
@cindex vfork events, remote reply
@item vfork
The packet indicates that @code{vfork} was called, and @var{r}
is the thread ID of the new child process. Refer to
@ref{thread-id syntax} for the format of the @var{thread-id}
field. This packet is only applicable to targets that support
vfork events.
@cindex vforkdone events, remote reply
@item vforkdone
The packet indicates that a child process created by a vfork
has either called @code{exec} or terminated, so that the
address spaces of the parent and child process are no longer
shared. The @var{r} part is ignored. This packet is only
applicable to targets that support vforkdone events.
Unfortunately, this is not just a documentation issue. GDBserver
is really not specifying the thread ID. I noticed because
in non-stop mode, gdb complains:
[Thread 6089.6089] #1 stopped.

This is not non-stop-mode-specific, however. Consider e.g., that in
all-stop, you may be debugging more than one process at the same time.
You continue, and both processes vfork. So when you next get a
T05vforkdone, there's no way to tell which of the parent processes is
done with the vfork.
Tests will be added later.
Tested on x86_64 Fedora 20.

Nowadays, GDB only knows whether architecture supports hardware single
step or software single step (through gdbarch hook software_single_step),
and for a given instruction or instruction sequence, GDB knows how to
do single step (hardware or software). However, GDB doesn't know whether
the target supports hardware single step. It is possible that the
architecture doesn't support hardware single step, such as arm, but
the target supports, such as simulator. This was discussed in this
thread https://www.sourceware.org/ml/gdb/2009-12/msg00033.html before.
I encounter this problem for aarch64 multi-arch support. When aarch64
debugs arm program, gdbarch is arm, so software single step is still
used. However, the underneath linux kernel does support hardware
single step, so IWBN to use it.
This patch is to add a new target_ops hook to_can_do_single_step, and
only use it in arm_linux_software_single_step to decide whether or not
to use hardware single step. On the native aarch64 linux target, 1 is
returned. On other targets, -1 is returned. On the remote target, if
the target supports s and S actions in the vCont? reply, then target
can do single step. However, old GDBserver will send s and S in the
reply to vCont?, which will confuse new GDB. For example, old GDBserver
on arm-linux will send s and S in the reply to vCont?, but it doesn't
support hardware single step. On the other hand, new GDBserver, on
arm-linux for example, will not send s and S in the reply to vCont?,
but old GDB thinks it doesn't support vCont packet at all. In order
to address this problem, I add a new qSupported feature vContSupported,
which indicates GDB wants to know the supported actions in the reply
to vCont?, and qSupported response contains vContSupported if the
stub is able tell supported vCont actions in the reply of vCont?.
If the patched GDB talks with patched GDBserver on x86, the RSP traffic
is like this:
-> $qSupported:...+;vContSupported+
<- ...+;vContSupported+
...
-> $vCont?
<- vCont;c;C;t;s;S;r
then, GDB knows the stub can do single step, and may stop using software
single step even the architecture doesn't support hardware single step.
If the patched GDB talks with patched GDBserver on arm, the last vCont?
reply will become:
<- vCont;c;C;t
GDB thinks the target doesn't support single step, so it will use software
single step.
If the patched GDB talks with unpatched GDBserver, the RSP traffic is like
this:
-> $qSupported:...+;vContSupported+
<- ...+
...
-> $vCont?
<- vCont;c;C;t;s;S;r
although GDBserver returns s and S, GDB still thinks GDBserver may not
support single step because it doesn't support vContSupported.
If the unpatched GDB talks with patched GDBserver on x86, the RSP traffic
is like:
-> $qSupported:...+;
<- ...+;vContSupported+
...
-> $vCont?
<- vCont;c;C;t;s;S;r
Since GDB doesn't sent vContSupported in the qSupported feature, GDBserver
sends s and S regardless of the support of hardware single step.

This finally implements user-visible all-stop mode running with the
target_ops backend always in non-stop mode. This is a stepping stone
towards finer-grained control of threads, being able to do interesting
things like thread groups, associating groups with breakpoints, etc.
From the user's perspective, all-stop mode is really just a special
case of being able to stop and resume specific sets of threads, so it
makes sense to do this step first.
With this, even in all-stop, the target is no longer in charge of
stopping all threads before reporting an event to the core -- the core
takes care of it when it sees fit. For example, when "next"- or
"step"-ing, we can avoid stopping and resuming all threads at each
internal single-step, and instead only stop all threads when we're
about to present the stop to the user.
The implementation is almost straight forward, as the heavy lifting
has been done already in previous patches. Basically, we replace
checks for "set non-stop on/off" (the non_stop global), with calls to
a new target_is_non_stop_p function. In a few places, if "set
non-stop off", we stop all threads explicitly, and in a few other
places we resume all threads explicitly, making use of existing
methods that were added for teaching non-stop to step over breakpoints
without displaced stepping.
This adds a new "maint set target-non-stop on/off/auto" knob that
allows both disabling the feature if we find problems, and
force-enable it for development (useful when teaching a target about
this. The default is "auto", which means the feature is enabled if a
new target method says it should be enabled. The patch implements the
method in linux-nat.c, just for illustration, because it still returns
false. We'll need a few follow up fixes before turning it on by
default. This is a separate target method from indicating regular
non-stop support, because e.g., while e.g., native linux-nat.c is
close to regression free with all-stop-non-stop (with following
patches will fixing the remaining regressions), remote.c+gdbserver
will still need more fixing, even though it supports "set non-stop
on".
Tested on x86_64 Fedora 20, native, with and without "set displaced
off", and with and without "maint set target-non-stop on"; and also
against gdbserver.

The documentation for the 'frame' command has gotten a little out of
date, it still mentions architecturally specific details that are no
longer relevant.
This commit removes the old details that no longer apply, and tries to
expand the existing text a little to make the usage clearer for some
cases.
gdb/doc/ChangeLog:
* gdb.texinfo (Selection): Update documentation for 'frame'
command.

Changes the documentation for the layout and focus commands.
Instead of documenting each layout (or focus) sub-command as a separate
command, document a single layout (and focus) command which takes a
parameter, then list the possible parameters in a table nested under
each command.
The documentation for the layout command has been extended little to
make it clearer which windows are shown in each layout.
gdb/ChangeLog:
* doc/gdb.texinfo (TUI): Restructure documentation on TUI layout
and focus commands.

This patch implements the new option "history remove-duplicates", which
controls the removal of duplicate history entries ("off" by default).
The motivation for this option is to be able to reduce the prevalence of
basic commands such as "up" and "down" in the history file. These
common commands crowd out more unique commands in the history file (when
the history file has a fixed size), and they make navigation of the
history file via ^P, ^N and ^R more inconvenient.
The option takes an integer denoting the number of history entries to
look back at for a history entry that is a duplicate of the latest one.
"history remove-duplicates 1" is equivalent to bash's ignoredups option,
and "history remove-duplicates unlimited" is equivalent to bash's
erasedups option.
[ I decided to go with this integer approach instead of a tri-state enum
because it's slightly more flexible and seemingly more intuitive than
leave/erase/ignore. ]
gdb/ChangeLog:
* NEWS: Mention the new option "history remove-duplicates".
* top.c (history_remove_duplicates): New static variable.
(show_history_remove_duplicates): New static function.
(gdb_add_history): Conditionally remove duplicate history
entries.
(init_main): Add "history remove-duplicates" option.
gdb/doc/ChangeLog:
* gdb.texinfo (Command History): Document the new option
"history remove-duplicates".

... by mentioning in the manual that setting GDBHISTSIZE to the empty
string disables truncation, like the NEWS entry does.
gdb/doc/ChangeLog:
* gdb.texinfo (Command History): Mention that setting
GDBHISTSIZE to the empty string disables history truncation.

When GDB reads a nonsensical value for the GDBHISTSIZE environment
variable, i.e. one that is non-numeric or negative, GDB then sets its
history size to 0. This behavior is annoying and also inconsistent
with the behavior of bash.
This patch makes the behavior of invalid GDBHISTSIZE consistent with how
bash handles HISTSIZE. When we encounter a null or out-of-range
GDBHISTSIZE (outside of [0, INT_MAX]) we now set the history size to
unlimited instead of 0. When we encounter a non-numeric GDBHISTSIZE we
do nothing.
gdb/ChangeLog:
PR gdb/16999
* NEWS: Mention new GDBHISTSIZE behavior.
* top.c (init_history): For null or out-of-range GDBHISTSIZE,
set history size to unlimited. Ignore non-numeric GDBHISTSIZE.

The HISTSIZE environment variable is generally expected to be read by
shells, not by applications. Some distros for example globally export
HISTSIZE in /etc/profile -- with the intention that it only affects
shells -- and by doing so it renders useless GDB's own mechanism for
setting the history size via .gdbinit. Also, annoyances may arise when
HISTSIZE is not interpreted the same way by the shell and by GDB, e.g.
PR gdb/16999. That can always be fixed on a shell-by-shell basis but it
may be impossible to be consistent with the behavior of all shells at
once. Finally it just makes sense to not confound shell environment
variables with application environment variables.
gdb/ChangeLog:
* NEWS: Mention that GDBHISTSIZE is read instead of HISTSIZE.
* top.c (init_history): Read from GDBHISTSIZE instead of
HISTSIZE.
(init_main): Refer to GDBHISTSIZE instead of HISTSIZE.
gdb/doc/ChangeLog:
* gdb.texinfo (Command History): Replace occurrences of HISTSIZE

New in v3:
* Change RSP documentation as well. The m, M and X packets now use
lengths in addressable memory units.
New in v2:
* Change wording: use byte for 8-bits chunks and addressable memory unit
for the unit of data associated to a single address.
* Introduce definition of addressable memory unit in the Memory
section.
This patch modifies the manual to clarify the MI, RSP and Python APIs in
regard to reading/writing memory on architectures with addressable
memory unit that are not 8 bits.
Care is taken to use the word "addressable memory unit" or "memory unit"
when referring to one piece of the smallest addressable size on the
current architecture and the word "byte" when referring to an 8-bits
data piece.
For MI, -data-{read,write}-memory are not modified, since they are
deprecated.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Data Manipulation): Clarify usage of
bytes and memory units for -data-{read,write}-memory-bytes.
(Packets): Same for m, M and X packets.
* python.texi (Inferiors In Python): Same for read_memory and
write_memory.

This promotes BFD's struct elf_build_id to the generic struct bfd_build_id,
populated when an ELF or PE BFD is read.
gdb is updated to use that, and to use the build-id to find symbols for PE files
also.
There is currently no generic way to extract the build-id from an object file,
perhaps an option to objdump to do this might make sense?
On x86_64-pc-cygwin, gdb's sepdebug.exp changes:
-# of unsupported tests 1
+# of expected passes 90
I don't seem to get consistent testsuite runs on i686-linux-gnu, but there
don't appear to be any regressions.

We previously specified a few known register groups for the 'tui reg'
command. Other register groups could be accessed, but only by using the
'tui reg next' command and cycling through all the groups.
This commit removes the hard coded sub-commands of 'tui reg' and instead
adds dynamic completion of sub-commands based on the architecturally
defined register groups, giving immediate access to all available
register groups.
There is still the 'next' and 'prev' commands for cycling through the
register groups if that's wanted.
The new code maintains the ability to only enter partial names for
register groups, which is something we got for free when using the
standard sub-command mechanism.
The register (and register group) completer has been changed to use
get_current_arch rather than using the architecture of the currently
selected frame. When the target is running, this is equivalent,
however, when the target is not running, using get_current_arch will
provide results from the default architecture.
gdb/ChangeLog:
* completer.c: Add arch-utils.h include.
(enum reg_completer_targets): New enum.
(reg_or_group_completer_1): New function containing old

Types used for some variables could not be used for 32 bits, causing a
compilation failure.
This patch adds a cast to force a quite compilation, but at the same
time it bails out in the case that the cast performed is not safe, i.e.
in the case where the debuggee is 64bit and debugger is 32bit.
Documentation was also affected, once a different version of texinfo the
docs could not be build.

Intel(R) Memory protection bound information are located in register
to be tested using the MPX new instructions. Since the number of
bound registers are limited a table is used to provide storage for
bounds during run-time.
In order to investigate the contents of the MPX bound table two new
commands are added to GDB. "show mpx bound" and "set mpx bound" are
used to display and set values on the MPX bound table.

It is planned the existing GDB command 'print' will be able to evaluate its
expressions using the compiler. There will be some option to choose between
the existing GDB evaluation and the compiler evaluation. But as an
intermediate step this patch provides the expression printing feature as a new
command.
I can imagine it could be also called 'maintenance compile print' as in the
future one should be able to use its functionality by the normal 'print'
command.
There was a discussion with Eli about the command name:
https://sourceware.org/ml/gdb-patches/2015-03/msg00880.html
As there were no other comments yet I haven't renamed it yet, before there is
some confirmation about settlement on the final name.
Support for the GDB '@' operator to create arrays has been submitted for GCC:

This commit allows GDB to determine filenames of main executables
when debugging using remote stubs without multiprocess extensions.
The qXfer:exec-file:read packet is extended to allow an empty
annex, with the meaning that the remote stub should supply the
filename of whatever it thinks is the current process.
gdb/ChangeLog:
* remote.c (remote_add_inferior): Call exec_file_locate_attach
for fake PIDs as well as real ones.
(remote_pid_to_exec_file): Send empty annex if PID is fake.
gdb/doc/ChangeLog:
* gdb.texinfo (General Query Packets): Document
qXfer:exec-file:read with empty annex.
gdb/gdbserver/ChangeLog:
* server.c (handle_qxfer_exec_file): Use current process
if annex is empty.
