Replace most calls to help_list and cmd_show_list
Currently there are many prefix commands that do nothing but call either help_list or cmd_show_list. I happened to notice that one such call, for "set print type", used the wrong command list parameter, causing incorrect output. Rather than fix this bug in isolation, I decided to eliminate this possibility by adding two new ways to add prefix commands, which simply route the call to help_list or cmd_show_list, as appropriate. This makes it impossible for a mismatch to occur. In some cases, a bit of output was removed; however, I don't think this output in general was very useful. It seemed redundant with what's already printed by help_list. A representative example is this hunk, removed from ada-lang.c: - printf_unfiltered (_(\ -"\"set ada\" must be followed by the name of a setting.\n")); This simplified the CLI style set/show commands quite a bit, and allowed the deletion of a macro. This also cleans up some unusual code in windows-tdep.c. Tested on x86-64 Fedora 30. Note that I have no way to build the go32-nat.c change. gdb/ChangeLog 2020-04-17 Tom Tromey <tromey@adacore.com> * auto-load.c (show_auto_load_cmd): Remove.

gdb/remote: do not check for null_ptid in stop reply
A gdbserver does not report a ptid in a 'W' or 'X' packet if multi-process extensions are not supported or turned off. See https://sourceware.org/gdb/current/onlinedocs/gdb/General-Query-Packets.html#multiprocess-extensions https://sourceware.org/gdb/current/onlinedocs/gdb/Stop-Reply-Packets.html#Stop-Reply-Packets GDB's remote packet parser checks for whether a stop-reply packet contains a ptid if the target is non-stop, and issues an error if no ptid is included: if (target_is_non_stop_p () && event->ptid == null_ptid) error (_("No process or thread specified in stop reply: %s"), buf); This leads to the following error when the non-stop mode is turned on but multi-process extensions are off: $ gdb (gdb) set non-stop on (gdb) set remote multiprocess-feature-packet off (gdb) target remote | gdbserver - ./foo Remote debugging using | gdbserver - ./foo stdin/stdout redirected Process ./foo created; pid = 3712 ... (gdb) continue Continuing. ... No process or thread specified in stop reply: W2a (gdb) Because the check is done for stop reply packets in general, a similar situation occurs if the 'T' or 'Tthread' packet is disabled in gdbserver (i.e. via --disable-packet=T). E.g: $ gdb (gdb) set non-stop on (gdb) target remote | gdbserver --disable-packet=Tthread - ./foo ... No process or thread specified in stop reply: T0506:0000000000000000;07:10e2ffffff7f0000;10:9060ddf7ff7f0000; or $ gdb (gdb) set non-stop on (gdb) target remote | gdbserver --disable-packet=T - ./foo ...

Make fputs_unfiltered use fputs_maybe_filtered
This patch redefines fputs_unfiltered in utils.c, with new behavior to
forward parameters to fputs_maybe_filtered. This makes
fputs_unfiltered identical to fputs_filtered, except filtering is
disabled.
Some callers of fputs_unfiltered have been updated to use ui_file_puts
where they were using other ui_file_* functions anyway for IO.
This fixes the problem I saw with \032\032post-prompt annotation being
flushed to stdout in the wrong order.

Implement 'set/show exec-file-mismatch'.
This option allows to tell GDB to detect and possibly handle mismatched exec-files. A recurrent problem with GDB is that GDB uses the wrong exec-file when using the attach/detach commands successively. Also, in case the user specifies a file on the command line but attaches to the wrong PID, this error is not made visible and gives a not user understandable behaviour. For example: $ gdb ...

(in this case, 31069 is the PID of a GDB, that has nothing to do with the first determined 'sleepers' executable). Similarly, if specifying an executable, but attaching to a wrong pid, we get: gdb /home/philippe/valgrind/git/trunk_untouched/gdbserver_tests/sleepers ...

() (gdb) And it is unclear to the user what has happened/what is going wrong. This patch series implements a new option: (gdb) apropos exec-file-mismatch set exec-file-mismatch -- Set exec-file-mismatch handling (ask|warn|off). show exec-file-mismatch -- Show exec-file-mismatch handling (ask|warn|off). (gdb) help set exec-file-mismatch Set exec-file-mismatch handling (ask|warn|off). Specifies how to handle a mismatch between the current exec-file name loaded by GDB and the exec-file name automatically determined when attaching to a process: ask - warn the user and ask whether to load the determined exec-file. warn - warn the user, but do not change the exec-file. off - do not check for mismatch. "ask" means: in case of mismatch between the current exec-file name and the automatically determined exec-file name of the PID we are attaching to, give a warning to the user and ask whether to load the automatically determined exec-file. "warn" means: in case of mismatch, just give a warning to the user. "off" means: do not check for mismatch. This fixes PR gdb/17626. There was a previous trial to fix this PR. See https://sourceware.org/ml/gdb-patches/2015-07/msg00118.html This trial was however only fixing the problem for the automatically determined executable files when doing attach. It was differentiating the 'user specified executable files' ("sticky") from the executable files automatically found by GDB. But such user specified sticky executables are in most cases due to a wrong manipulation by the user, giving unexpected results such as backtrace showing no function like in the above example.

The default value of "ask" is chosen instead of e.g. "warn" as in most cases, switching of executable will be the correct action, and in any case, the user can decide to not load the executable, as GDB asks a confirmation to the user to load the new executable. For settings "ask" and "warn", the new function validate_exec_file () tries to get the inferior pid exec file and compares it with the current exec file. In case of mismatch, it warns the user and optionally load the executable. This function is called in the attach_command implementation to cover most cases of attaching to a running process.

gdb: add back declarations for _initialize functions
I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:

Add "info connections" command, "info inferiors" connection number/string
This commit extends the CLI a bit for multi-target, in three ways. #1 - New "info connections" command. This is a new command that lists the open connections (process_stratum targets). For example, if you're debugging two remote connections, a couple local/native processes, and a core dump, all at the same time, you might see something like this: (gdb) info connections Num What Description 1 remote 192.168.0.1:9999 Remote serial target in gdb-specific protocol 2 remote 192.168.0.2:9998 Remote serial target in gdb-specific protocol * 3 native Native process 4 core Local core dump file #2 - New "info inferiors" "Connection" column You'll also see a new matching "Connection" column in "info inferiors", showing you which connection an inferior is bound to: (gdb) info inferiors Num Description Connection Executable 1 process 18526 1 (remote 192.168.0.1:9999) target:/tmp/a.out 2 process 18531 2 (remote 192.168.0.2:9998) target:/tmp/a.out 3 process 19115 3 (native) /tmp/prog1 4 process 6286 4 (core) myprogram * 5 process 19122 3 (native) /bin/hello #3 - Makes "add-inferior" show the inferior's target connection "add-inferior" now shows you the connection you've just bound the inferior to, which is the current process_stratum target: (gdb) add-inferior [New inferior 2] Added inferior 2 on connection 1 (extended-remote localhost:2346) gdb/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add target-connection.c. * inferior.c (uiout_field_connection): New function.

Multi-target support
This commit adds multi-target support to GDB. What this means is that
with this commit, GDB can now be connected to different targets at the
same time. E.g., you can debug a live native process and a core dump
at the same time, connect to multiple gdbservers, etc.
Actually, the word "target" is overloaded in gdb. We already have a
target stack, with pushes several target_ops instances on top of one
another. We also have "info target" already, which means something
completely different to what this patch does.
So from here on, I'll be using the "target connections" term, to mean
an open process_stratum target, pushed on a target stack. This patch
makes gdb have multiple target stacks, and multiple process_stratum
targets open simultaneously. The user-visible changes / commands will
also use this terminology, but of course it's all open to debate.
User-interface-wise, not that much changes. The main difference is
that each inferior may have its own target connection.
A target connection (e.g., a target extended-remote connection) may
support debugging multiple processes, just as before.
Say you're debugging against gdbserver in extended-remote mode, and
you do "add-inferior" to prepare to spawn a new process, like:
(gdb) target extended-remote :9999
...
(gdb) start
...
(gdb) add-inferior
Added inferior 2
(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]
(gdb) file a.out
...
(gdb) start
...
At this point, you have two inferiors connected to the same gdbserver.
With this commit, GDB will maintain a target stack per inferior,
instead of a global target stack.
To preserve the behavior above, by default, "add-inferior" makes the
new inferior inherit a copy of the target stack of the current
inferior. Same across a fork - the child inherits a copy of the
target stack of the parent. While the target stacks are copied, the
targets themselves are not. Instead, target_ops is made a
refcounted_object, which means that target_ops instances are
refcounted, which each inferior counting for a reference.
What if you want to create an inferior and connect it to some _other_
target? For that, this commit introduces a new "add-inferior
-no-connection" option that makes the new inferior not share the
current inferior's target. So you could do:
(gdb) target extended-remote :9999
Remote debugging using :9999
...
(gdb) add-inferior -no-connection
[New inferior 2]
Added inferior 2
(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]
(gdb) info inferiors
Num Description Executable
1 process 18401 target:/home/pedro/tmp/main
* 2 <null>
(gdb) tar extended-remote :10000
Remote debugging using :10000
...
(gdb) info inferiors
Num Description Executable
1 process 18401 target:/home/pedro/tmp/main
* 2 process 18450 target:/home/pedro/tmp/main
(gdb)
A following patch will extended "info inferiors" to include a column
indicating which connection an inferior is bound to, along with a
couple other UI tweaks.
Other than that, debugging is the same as before. Users interact with
inferiors and threads as before. The only difference is that
inferiors may be bound to processes running in different machines.
That's pretty much all there is to it in terms of noticeable UI
changes.
On to implementation.
Since we can be connected to different systems at the same time, a
ptid_t is no longer a unique identifier. Instead a thread can be
identified by a pair of ptid_t and 'process_stratum_target *', the
later being the instance of the process_stratum target that owns the
process/thread. Note that process_stratum_target inherits from
target_ops, and all process_stratum targets inherit from
process_stratum_target. In earlier patches, many places in gdb were
converted to refer to threads by thread_info pointer instead of
ptid_t, but there are still places in gdb where we start with a
pid/tid and need to find the corresponding inferior or thread_info
objects. So you'll see in the patch many places adding a
process_stratum_target parameter to functions that used to take only a
ptid_t.
Since each inferior has its own target stack now, we can always find
the process_stratum target for an inferior. That is done via a
inf->process_target() convenience method.
Since each inferior has its own target stack, we need to handle the
"beneath" calls when servicing target calls. The solution I settled
with is just to make sure to switch the current inferior to the
inferior you want before making a target call. Not relying on global
context is just not feasible in current GDB. Fortunately, there
aren't that many places that need to do that, because generally most
code that calls target methods already has the current context
pointing to the right inferior/thread. Note, to emphasize -- there's
no method to "switch to this target stack". Instead, you switch the
current inferior, and that implicitly switches the target stack.
In some spots, we need to iterate over all inferiors so that we reach
all target stacks.
Native targets are still singletons. There's always only a single
instance of such targets.
Remote targets however, we'll have one instance per remote connection.
The exec target is still a singleton. There's only one instance. I
did not see the point of instanciating more than one exec_target
object.
After vfork, we need to make sure to push the exec target on the new
inferior. See exec_on_vfork.
For type safety, functions that need a {target, ptid} pair to identify
a thread, take a process_stratum_target pointer for target parameter
instead of target_ops *. Some shared code in gdb/nat/ also need to
gain a target pointer parameter. This poses an issue, since gdbserver
doesn't have process_stratum_target, only target_ops. To fix this,
this commit renames gdbserver's target_ops to process_stratum_target.
I think this makes sense. There's no concept of target stack in
gdbserver, and gdbserver's target_ops really implements a
process_stratum-like target.
The thread and inferior iterator functions also gain
process_stratum_target parameters. These are used to be able to
iterate over threads and inferiors of a given target. Following usual
conventions, if the target pointer is null, then we iterate over
threads and inferiors of all targets.
I tried converting "add-inferior" to the gdb::option framework, as a
preparatory patch, but that stumbled on the fact that gdb::option does
not support file options yet, for "add-inferior -exec". I have a WIP
patchset that adds that, but it's not a trivial patch, mainly due to
need to integrate readline's filename completion, so I deferred that
to some other time.
In infrun.c/infcmd.c, the main change is that we need to poll events
out of all targets. See do_target_wait. Right after collecting an
event, we switch the current inferior to an inferior bound to the
target that reported the event, so that target methods can be used
while handling the event. This makes most of the code transparent to
multi-targets. See fetch_inferior_event.
infrun.c:stop_all_threads is interesting -- in this function we need
to stop all threads of all targets. What the function does is send an
asynchronous stop request to all threads, and then synchronously waits
for events, with target_wait, rinse repeat, until all it finds are
stopped threads. Now that we have multiple targets, it's not
efficient to synchronously block in target_wait waiting for events out
of one target. Instead, we implement a mini event loop, with
interruptible_select, select'ing on one file descriptor per target.
For this to work, we need to be able to ask the target for a waitable
file descriptor. Such file descriptors already exist, they are the
descriptors registered in the main event loop with add_file_handler,
inside the target_async implementations. This commit adds a new
target_async_wait_fd target method that just returns the file
descriptor in question. See wait_one / stop_all_threads in infrun.c.
The 'threads_executing' global is made a per-target variable. Since
it is only relevant to process_stratum_target targets, this is where
it is put, instead of in target_ops.
You'll notice that remote.c includes some FIXME notes. These refer to
the fact that the global arrays that hold data for the remote packets
supported are still globals. For example, if we connect to two
different servers/stubs, then each might support different remote
protocol features. They might even be different architectures, like
e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a
host/controller scenario as a single program. That isn't going to
work correctly today, because of said globals. I'm leaving fixing
that for another pass, since it does not appear to be trivial, and I'd
rather land the base work first. It's already useful to be able to
debug multiple instances of the same server (e.g., a distributed
cluster, where you have full control over the servers installed), so I
think as is it's already reasonable incremental progress.
Current limitations:
- You can only resume more that one target at the same time if all
targets support asynchronous debugging, and support non-stop mode.
It should be possible to support mixed all-stop + non-stop
backends, but that is left for another time. This means that
currently in order to do multi-target with gdbserver you need to
issue "maint set target-non-stop on". I would like to make that
mode be the default, but we're not there yet. Note that I'm
talking about how the target backend works, only. User-visible
all-stop mode works just fine.
- As explained above, connecting to different remote servers at the
same time is likely to produce bad results if they don't support the
exact set of RSP features.

Fix reconnecting to a gdbserver already debugging multiple processes, II
Another bug exposed by gdb.server/extended-remote-restart.exp in the
multi-target work is that remote_target::start_remote can leave
inferior_ptid and current_inferior() out of sync:
(top-gdb) p current_inferior_->pid
$1 = 29541
(top-gdb) p inferior_ptid
$2 = {m_pid = 29540, m_lwp = 29540, m_tid = 0}
This is caused by writing to inferior_ptid directly instead of using
switch_to_thread. Also, "inferior_list->thread_list->ptid" assumes
that we want the first thread of the first inferior, but that inferior
may not have threads, or with multi-target, that target may be
connected to some other target.
gdb/ChangeLog:
2020-01-10 Pedro Alves <palves@redhat.com>
* remote.c (remote_target::start_remote): Don't set inferior_ptid
directly. Instead find the first thread in the thread list and
use switch_to_thread.

Fix reconnecting to a gdbserver already debugging multiple processes, I
The multi-target patch will change the remote target's behavior when:
- the current inferior is connected to an extended-remote target.
- the current inferior is attached to any process.
- some other inferior than than the current one is live.
In current master, we get:
(gdb) tar extended-remote :9999
A program is being debugged already. Kill it? (y or n)
While after multi-target, since each inferior may have its own target
connection, we'll get:
(gdb) tar extended-remote :9999
Already connected to a remote target. Disconnect? (y or n)
That change made gdb.server/extended-remote-restart.exp expose a gdb
bug, because it made "target remote", via gdb_reconnect, just
disconnect from the previous connection, while in current master that
command would kill the inferior before disconnecting. In turn, that
would make a multi-target gdb find processes already running under
control of gdbserver as soon as it reconnects, while in current master
there is never any process around when gdb reconnects, since they'd
all been killed prior to disconnection.
The bug this exposed is that remote_target::remote_add_inferior was
always reusing current_inferior() for the new process, even if the
current inferior was already bound to a process. In the testcase's
case, when we reconnect, the remote is debugging two processes. So
we'd bind the first remote process to the empty current inferior the
first time, and then bind the second remote process to the same
inferior again, essencially losing track of the first process. That
resulted in failed assertions when we look up the inferior for the
first process by PID. The fix is to still prefer binding to the
current inferior (so that plain "target remote" keeps doing what you'd
expect), but not reuse the current inferior if it is already bound to
a process.
This patch tweaks the test to explicitly disconnect before
reconnecting, to avoid GDB killing processes, thus making current GDB
behave the same as it will behave when the multi-target work lands.
That change alone without the GDB fix exposes the bug like so:
(gdb) PASS: gdb.server/extended-remote-restart.exp: kill: 0, follow-child 0: disconnect
target extended-remote localhost:2350
Remote debugging using localhost:2350
src/gdb/thread.c:93: internal-error: thread_info* inferior_thread(): Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The original bug that the testcase was written for was related to
killing, (git

Avoid another inferior_ptid reference in gdb/remote.c
The multi-target patch makes inferior_ptid point to null_ptid before calling into target_wait, which catches bad uses of inferior_ptid, since the current selected thread in gdb shouldn't have much relation to the thread that reports an event. One such bad use is found in remote_target::remote_parse_stop_reply, where we handle the 'W' or 'X' packets (process exit), and the remote target does not support the multi-process extensions, i.e., it does not report the PID of the process that exited. With the multi-target patch, that would result in a failed assertion, trying to find the inferior for process pid 0. gdb/ChangeLog: 2020-01-10 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> Pedro Alves <palves@redhat.com> * remote.c (remote_target::remote_parse_stop_reply) <W/X packets>: If no process is specified, return null_ptid instead of inferior_ptid.

Tweak handling of remote errors in response to resumption packet
With current master, on a Fedora 27 machine with a kernel with buggy
watchpoint support, I see:
(gdb) PASS: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: hardware breakpoints work
continue
Continuing.
warning: Remote failure reply: E01
Remote communication error. Target disconnected.: Connection reset by peer.
(gdb) FAIL: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: watchpoints work
continue
The program is not being run.
(gdb) FAIL: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: breakpoint after the first fork (the program is no longer running)
The FAILs themselves aren't what's interesting here. What is
interesting is that with the main multi-target patch applied, I was getting this:
(gdb) PASS: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: hardware breakpoints work
continue
Continuing.
warning: Remote failure reply: E01
/home/pedro/brno/pedro/gdb/binutils-gdb-2/build/../src/gdb/inferior.c:285: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: watchpoints work (GDB internal error)
The problem is that in remote_target::wait_as, we're hitting this:
switch (buf[0])
{
case 'E': /* Error of some sort. */
/* We're out of sync with the target now. Did it continue or
not? Not is more likely, so report a stop. */
rs->waiting_for_stop_reply = 0;
warning (_("Remote failure reply: %s"), buf);
status->kind = TARGET_WAITKIND_STOPPED;
status->value.sig = GDB_SIGNAL_0;
break;
which leaves event_ptid as null_ptid. At the end of the function, we then reach:
else if (status->kind != TARGET_WAITKIND_EXITED
&& status->kind != TARGET_WAITKIND_SIGNALLED)
{
if (event_ptid != null_ptid)
record_currthread (rs, event_ptid);
else
event_ptid = inferior_ptid; <<<<< here
}
and the trouble is that with the multi-target patch, we'll get here
with inferior_ptid as null_ptid too. That is done exactly to find
these implicit assumptions that inferior_ptid is a good choice for
default thread, which isn't generaly true.
I first thought of fixing this in the "case 'E'" path, but, given that
this "event_ptid = inferior_ptid" path is also taken when the remote
target does not support threads at all, no thread-related packets or
extensions, it's better to fix it in latter path, to handle all
scenarios that miss reporting a thread.
That's what this patch does.
gdb/ChangeLog:
2020-01-10 Pedro Alves <palves@redhat.com>
* remote.c (first_remote_resumed_thread): New.
(remote_target::wait_as): Use it as default event_ptid instead of
inferior_ptid.

Don't check target is running in remote_target::mourn_inferior
I believe the tail end of remote_target::mourn_inferior is broken, and
it's been broken for too long to even bother trying to fix. Most
probably nobody needs it. If the code is reached and we find the
target is running, we'd need to resync the thread list, at least,
since generic_mourn_inferior got rid of all the threads in the
inferior, otherwise, we'd hit an assertion on the next call to
inferior_thread(), for example. A "correct" fix would probably
involve restarting the whole remote_target::start_remote requence,
exactly as if we had completely disconnected and reconnected from
scratch.
Note that regular stub debugging usually uses plain target remote, but
this code is only reachable in target extended-mode:
- The !remote_multi_process_p check means that it's only reacheable if
the stub does not support multi-process. I.e., there can only ever
be one live process.
- remote_target::mourn_inferior has this at the top:
/* In 'target remote' mode with one inferior, we close the connection. */
if (!rs->extended && number_of_live_inferiors () <= 1)
{
unpush_target (this);
/* remote_close takes care of doing most of the clean up. */
generic_mourn_inferior ();
return;
}
Which means that if we only had one live inferior (which for our
case, must be true), we'll have closed the connection already,
unless we're in extended-remote mode.

2020-01-10 Pedro Alves <palves@redhat.com>
* remote.c (remote_target::mourn_inferior): No longer check

Make "show remote exec-file" inferior-aware
The "set remote exec-file" setting is per-inferior, but the "show remote exec-file" command always shows the last set exec-file, irrespective of the current inferior. E.g.: # Set inferior 1's exec-file: (gdb) set remote exec-file prog1 # Add inferior 2, switch to it, and set its exec-file: (gdb) add-inferior Added inferior 2 (gdb) inferior 2 (gdb) set remote exec-file prog2 # Switch back to inferior 1, and show its exec-file: (gdb) inferior 1 (gdb) show remote exec-file prog2 ^^^^^ should show "prog1" instead here. gdb/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * remote.c (show_remote_exec_file): Show the current inferior's exec-file instead of the command variable's value. gdb/testsuite/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * gdb.base/remote-exec-file.exp: New file. |

Change section_offsets to a std::vector
This changes section_offsets to be specialization of a std::vector and
updates all the users. It also removes the ANOFFSET and
SIZEOF_N_SECTION_OFFSETS macros.
Most of this is just a generic sort of cleanup, that reduces the
number of lines of code. However, a couple spots were doing weird
things.
objfile_relocate did:
- std::vector<struct section_offsets>
- new_debug_offsets (SIZEOF_N_SECTION_OFFSETS (debug_objfile->num_sections));
... which seems to greatly over-estimate the number of elements
needed.
This appeared in set_objfile_default_section_offset:
- std::vector<struct section_offsets> offsets (objf->num_sections,
- { { offset } });
... which makes sense due to type safety, but is also actively
confusing given that section_offsets was previously also a kind of
vector type.
Tested on x86-64 Fedora 30.

Constify get_exec_file
I noticed that get_exec_file could return a "const char *". This patch implements this change. I couldn't build all the code -- but I did build Linux native and a mingw cross. Consequently, the NTO code has a hack, where it casts away const. I think this can be removed, but that required more work there, and since I couldn't compile it, I felt it best not to try.

[Debugging output] Make remote packet truncation length adjustable
While debugging, i felt the need to adjust the truncation length of remote packets so i could see more or less data as needed. The default is currently set to 512 bytes. This patch makes this option adjustable through the new "set debug remote-packet-max-chars" command. It can be set to unlimited if we want to completely disable truncation. Update on v5: - Adjusted function and variable documentation, NEWS entry and GDB manual. gdb/ChangeLog: 2019-11-25 Luis Machado <luis.machado@linaro.org> * NEWS (New Commands): Mention "set debug remote-packet-max-chars". * remote.c (REMOTE_DEBUG_MAX_CHAR): Remove.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

Improve remote attach round-trips without btrace
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.
gdb/ChangeLog:
* remote.c (remote_target::remote_btrace_maybe_reopen): Avoid
unnecessary thread walk if remote doesn't support the packet.

With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise. It now prints the full first line, except when FOR_VALUE_PREFIX. In this case, the trailing '.' is not output, and the first character is uppercased.

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.
