internal_error: remove need to pass __FILE__/__LINE__
Currently, every internal_error call must be passed __FILE__/__LINE__
explicitly, like:
internal_error (__FILE__, __LINE__, "foo %d", var);
The need to pass in explicit __FILE__/__LINE__ is there probably
because the function predates widespread and portable variadic macros
availability. We can use variadic macros nowadays, and in fact, we
already use them in several places, including the related
gdb_assert_not_reached.
So this patch renames the internal_error function to something else,
and then reimplements internal_error as a variadic macro that expands
__FILE__/__LINE__ itself.
The result is that we now should call internal_error like so:
internal_error ("foo %d", var);
Likewise for internal_warning.
The patch adjusts all calls sites. 99% of the adjustments were done
with a perl/sed script.
The non-mechanical changes are in gdbsupport/errors.h,
gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

Change GDB to use frame_info_ptr
This changes GDB to use frame_info_ptr instead of frame_info *
The substitution was done with multiple sequential `sed` commands:
sed 's/^struct frame_info;/class frame_info_ptr;/'
sed 's/struct frame_info \*/frame_info_ptr /g' - which left some
issues in a few files, that were manually fixed.
sed 's/\<frame_info \*/frame_info_ptr /g'
sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace
problems.
The changed files were then manually checked and some 'sed' changes
undone, some constructors and some gets were added, according to what
made sense, and what Tromey originally did

gdb: make use of SCOPE_EXIT to manage thread executing state
While working on another patch relating to how GDB manages threads
executing and resumed state, I spotted the following code in
record-btrace.c:
executing = tp->executing ();
set_executing (proc_target, inferior_ptid, false);
id = null_frame_id;
try
{
id = get_frame_id (get_current_frame ());
}
catch (const gdb_exception &except)
{
/* Restore the previous execution state. */
set_executing (proc_target, inferior_ptid, executing);
throw;
}
/* Restore the previous execution state. */
set_executing (proc_target, inferior_ptid, executing);
return id;
I notice that we only catch the exception so we can call
set_executing, and this is the same call to set_executing that we need
to perform in the non-exception return path.
This would be much cleaner if we could use SCOPE_EXIT to avoid the
try/catch, so lets do that.
While cleaning this up, I also applied a similar patch to
record-full.c, though there's no try/catch in that case, but using
SCOPE_EXIT makes the code safe if, in the future, we do start throwing
exceptions.
There should be no user visible changes after this commit.

gdb, gdbserver: make target_waitstatus safe
I stumbled on a bug caused by the fact that a code path read
target_waitstatus::value::sig (expecting it to contain a gdb_signal
value) while target_waitstatus::kind was TARGET_WAITKIND_FORKED. This
meant that the active union field was in fact
target_waitstatus::value::related_pid, and contained a ptid. The read
signal value was therefore garbage, and that caused GDB to crash soon
after. Or, since that GDB was built with ubsan, this nice error
message:
/home/simark/src/binutils-gdb/gdb/linux-nat.c:1271:12: runtime error: load of value 2686365, which is not a valid value for type 'gdb_signal'
Despite being a large-ish change, I think it would be nice to make
target_waitstatus safe against that kind of bug. As already done
elsewhere (e.g. dynamic_prop), validate that the type of value read from
the union matches what is supposed to be the active field.
- Make the kind and value of target_waitstatus private.
- Make the kind initialized to TARGET_WAITKIND_IGNORE on
target_waitstatus construction. This is what most users appear to do
explicitly.
- Add setters, one for each kind. Each setter takes as a parameter the
data associated to that kind, if any. This makes it impossible to
forget to attach the associated data.
- Add getters, one for each associated data type. Each getter
validates that the data type fetched by the user matches the wait
status kind.
- Change "integer" to "exit_status", "related_pid" to "child_ptid",
just because that's more precise terminology.
- Fix all users.
That last point is semi-mechanical. There are a lot of obvious changes,
but some less obvious ones. For example, it's not possible to set the
kind at some point and the associated data later, as some users did.
But in any case, the intent of the code should not change in this patch.
This was tested on x86-64 Linux (unix, native-gdbserver and
native-extended-gdbserver boards). It was built-tested on x86-64
FreeBSD, NetBSD, MinGW and macOS. The rest of the changes to native
files was done as a best effort. If I forgot any place to update in
these files, it should be easy to fix (unless the change happens to
reveal an actual bug).

gdb: make thread_info::executing private
Rename thread_info::executing to thread_info::m_executing, and make it private. Add a new get/set member functions, and convert GDB to make use of these. The only real change of interest in this patch is in thread.c where I have deleted the helper function set_executing_thread, and now just use the new set function thread_info::set_executing. However, the old helper function set_executing_thread included some code to reset the thread's stop_pc, so I moved this code into the new function thread_info::set_executing. However, I don't believe there is anywhere that this results in a change of behaviour, previously the executing flag was always set true through a call to set_executing_thread anyway. |

gdb: make thread_info::suspend private, add getters / setters
A following patch will want to take some action when a pending wait
status is set on or removed from a thread. Add a getter and a setter on
thread_info for the pending waitstatus, so that we can add some code in
the setter later.
The thing is, the pending wait status field is in the
thread_suspend_state, along with other fields that we need to backup
before and restore after the thread does an inferior function call.
Therefore, make the thread_suspend_state member private
(thread_info::suspend becomes thread_info::m_suspend), and add getters /
setters for all of its fields:
- pending wait status
- stop signal
- stop reason
- stop pc
For the pending wait status, add the additional has_pending_waitstatus
and clear_pending_waitstatus methods.
I think this makes the thread_info interface a bit nicer, because we
now access the fields as:
thread->stop_pc ()
rather than
thread->suspend.stop_pc
The stop_pc field being in the `suspend` structure is an implementation
detail of thread_info that callers don't need to be aware of.
For the backup / restore of the thread_suspend_state structure, add
save_suspend_to and restore_suspend_from methods. You might wonder why
`save_suspend_to`, as opposed to a simple getter like
thread_suspend_state &suspend ();
I want to make it clear that this is to be used only for backing up and
restoring the suspend state, _not_ to access fields like:
thread->suspend ()->stop_pc
Adding some getters / setters allows adding some assertions. I find
that this helps understand how things are supposed to work. Add:
- When getting the pending status (pending_waitstatus method), ensure
that there is a pending status.
- When setting a pending status (set_pending_waitstatus method), ensure
there is no pending status.
There is one case I found where this wasn't true - in
remote_target::process_initial_stop_replies - which needed adjustments
to respect that contract. I think it's because
process_initial_stop_replies is kind of (ab)using the
thread_info::suspend::waitstatus to store some statuses temporarily, for
its internal use (statuses it doesn't intent on leaving pending).
process_initial_stop_replies pulls out stop replies received during the
initial connection using target_wait. It always stores the received
event in `evthread->suspend.waitstatus`. But it only sets
waitstatus_pending_p, if it deems the event interesting enough to leave
pending, to be reported to the core:
if (ws.kind != TARGET_WAITKIND_STOPPED
|| ws.value.sig != GDB_SIGNAL_0)
evthread->suspend.waitstatus_pending_p = 1;
It later uses this flag a bit below, to choose which thread to make the
"selected" one:
if (selected == NULL
&& thread->suspend.waitstatus_pending_p)
selected = thread;
And ultimately that's used if the user-visible mode is all-stop, so that
we print the stop for that interesting thread:
/* In all-stop, we only print the status of one thread, and leave
others with their status pending. */
if (!non_stop)
{
thread_info *thread = selected;
if (thread == NULL)
thread = lowest_stopped;
if (thread == NULL)
thread = first;
print_one_stopped_thread (thread);
}
But in any case (all-stop or non-stop), print_one_stopped_thread needs
to access the waitstatus value of these threads that don't have a
pending waitstatus (those that had TARGET_WAITKIND_STOPPED +
GDB_SIGNAL_0). This doesn't work with the assertions I've
put.
So, change the code to only set the thread's wait status if it is an
interesting one that we are going to leave pending. If the thread
stopped due to a non-interesting event (TARGET_WAITKIND_STOPPED +
GDB_SIGNAL_0), don't store it. Adjust print_one_stopped_thread to
understand that if a thread has no pending waitstatus, it's because it
stopped with TARGET_WAITKIND_STOPPED + GDB_SIGNAL_0.
The call to set_last_target_status also uses the pending waitstatus.
However, given that the pending waitstatus for the thread may have been
cleared in print_one_stopped_thread (and that there might not even be a
pending waitstatus in the first place, as explained above), it is no
longer possible to do it at this point. To fix that, move the call to
set_last_target_status in print_one_stopped_thread. I think this will
preserve the existing behavior, because set_last_target_status is
currently using the current thread's wait status. And the current
thread is the last one for which print_one_stopped_thread is called. So
by calling set_last_target_status in print_one_stopped_thread, we'll get
the same result. set_last_target_status will possibly be called
multiple times, but only the last call will matter. It just means
possibly more calls to set_last_target_status, but those are cheap.

gdb: add names to unwinders, add debug messages when looking for unwinder
I wrote this while debugging a problem where the expected unwinder for a
frame wasn't used. It adds messages to show which unwinders are
considered for a frame, why they are not selected (if an exception is
thrown), and finally which unwinder is selected in the end.
To be able to show a meaningful, human-readable name for the unwinders,
add a "name" field to struct frame_unwind, and update all instances to
include a name.
Here's an example of the output:
[frame] frame_unwind_find_by_frame: this_frame=0
[frame] frame_unwind_try_unwinder: trying unwinder "dummy"
[frame] frame_unwind_try_unwinder: no

[frame] frame_unwind_try_unwinder: no
[frame] frame_unwind_try_unwinder: trying unwinder "inline"
[frame] frame_unwind_try_unwinder: no
[frame] frame_unwind_try_unwinder: trying unwinder "jit"
[frame] frame_unwind_try_unwinder: no
[frame] frame_unwind_try_unwinder: trying unwinder "python"
[frame] frame_unwind_try_unwinder: no
[frame] frame_unwind_try_unwinder: trying unwinder "amd64 epilogue"

gdb: generate the prefix name for prefix commands on demand
Previously, the prefixname field of struct cmd_list_element was manually set for prefix commands. This seems verbose and error prone as it required every single call to functions adding prefix commands to specify the prefix name while the same information can be easily generated. Historically, this was not possible as the prefix field was null for many commands, but this was fixed in commit 3f4d92ebdf7f848b5ccc9e8d8e8514c64fde1183 by Philippe Waroquiers, so we can rely on the prefix field being set when generating the prefix name. This commit also fixes a use after free in this scenario: * A command gets created via Python (using the gdb.Command class). The prefix name member is dynamically allocated. * An alias to the new command is created. The alias's prefixname is set to point to the prefixname for the original command with a direct assignment. * A new command with the same name as the Python command is created. * The object for the original Python command gets freed and its prefixname gets freed as well. * The alias is updated to point to the new command, but its prefixname is not updated so it keeps pointing to the freed one. gdb/ChangeLog: * command.h (add_prefix_cmd): Remove the prefixname argument as it can now be generated automatically.

gdb: make async event handlers clear themselves
The `ready` flag of async event handlers is cleared by the async event handler system right before invoking the associated callback, in check_async_event_handlers. This is not ideal with how the infrun subsystem consumes events: all targets' async event handler callbacks essentially just invoke `inferior_event_handler`, which eventually calls `fetch_inferior_event` and `do_target_wait`. `do_target_wait` picks an inferior at random, and thus a target at random (it could be the target whose `ready` flag was cleared, or not), and pulls one event from it. So it's possible that: - the async event handler for a target A is called - we end up consuming an event for target B - all threads of target B are stopped, target_async(0) is called on it, so its async event handler is cleared (e.g. record_btrace_target::async) As a result, target A still has events to report while its async event handler is left unmarked, so these events are not consumed. To counter this, at the end of their async event handler callbacks, targets check if they still have something to report and re-mark their async event handler (e.g. remote_async_inferior_event_handler). The linux_nat target does not suffer from this because it doesn't use an async event handler at the moment. It only uses a pipe registered with the event loop. It is written to in the SIGCHLD handler (and in other spots that want to get target wait method called) and read from in the target's wait method. So if linux_nat happened to be target A in the example above, the pipe would just stay readable, and the event loop would wake up again, until linux_nat's wait method is finally called and consumes the contents of the pipe. I think it would be nicer if targets using async_event_handler worked in a similar way, where the flag would stay set until the target's wait method is actually called. As a first step towards that, this patch moves the responsibility of clearing the ready flags of async event handlers to the invoked callback. All async event handler callbacks are modified to clear their ready flag before doing anything else. So in practice, nothing changes with this patch. It's only the responsibility of clearing the flag that is shifted toward the callee. gdb/ChangeLog: * async-event.h (async_event_handler_func): Add documentation. * async-event.c (check_async_event_handlers): Don't clear async_event_handler ready flag. * infrun.c (infrun_async_inferior_event_handler): Clear ready flag. * record-btrace.c (record_btrace_handle_async_inferior_event): Likewise. * record-full.c (record_full_async_inferior_event_handler): Likewise. * remote-notif.c (remote_async_get_pending_events_handler): Likewise. * remote.c (remote_async_inferior_event_handler): Likewise.

I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

Make target_wait options use enum flags
This changes TARGET_WNOHANG to be a member of an enum, rather than a define, and also adds a DEF_ENUM_FLAGS_TYPE for this type. Then, it changes target_wait and the various target wait methods to use this type rather than "int". This didn't catch any bugs, but it seems like a decent cleanup nevertheless. I did not change deprecated_target_wait_hook, since that's only used out-of-tree (by Insight), and there didn't seem to be a need. I can't build some of these targets, so I modified them on a best-effort basis.

Rewrite enum_flags, add unit tests, fix problems
This patch started by adding comprehensive unit tests for enum_flags.
For the testing part, it adds:
- tests of normal expected uses of the API.
- checks that _invalid_ uses of the API would fail to compile. I.e.,
it validates that enum_flags really is a strong type, and that
incorrect mixing of enum types would be caught at compile time. It
pulls that off making use of SFINEA and C++11's decltype/constexpr.
This revealed many holes in the enum_flags API. For example, the f1
assignment below currently incorrectly fails to compile:
enum_flags<flags> f1 = FLAG1;
enum_flags<flags> f2 = FLAG2 | f1;
The unit tests also revealed that this useful use case doesn't work:
enum flag { FLAG1 = 1, FLAG2 = 2 };
enum_flags<flag> src = FLAG1;
enum_flags<flag> f1 = condition ? src : FLAG2;
It fails to compile because enum_flags<flag> and flag are convertible
to each other.
Turns out that making enum_flags be implicitly convertible to the
backing raw enum type was not a good idea.
If we make it convertible to the underlying type instead, we fix that
ternary operator use case, and, we find cases throughout the codebase
that should be using the enum_flags but were using the raw backing
enum instead. So it's a good change overall.
Also, several operators were missing.
These holes and more are plugged by this patch, by reworking how the
enum_flags operators are implemented, and making use of C++11's
feature of being able to delete methods/functions.
There are cases in gdb/compile/ where we need to call a function in a
C plugin API that expects the raw enum. To address cases like that,
this adds a "raw()" method to enum_flags. This way we can keep using
the safer enum_flags to construct the value, and then be explicit when
we need to get at the raw enum.
This makes most of the enum_flags operators constexpr. Beyond
enabling more compiler optimizations and enabling the new unit tests,
this has other advantages, like making it possible to use operator|
with enum_flags values in switch cases, where only compile-time
constants are allowed:
enum_flags<flags> f = FLAG1 | FLAG2;
switch (f)
{
case FLAG1 | FLAG2:
break;
}
Currently that fails to compile.
It also switches to a different mechanism of enabling the global
operators. The current mechanism isn't namespace friendly, the new
one is.
It also switches to C++11-style SFINAE -- instead of wrapping the
return type in a SFINAE-friently structure, we use an unnamed template
parameter. I.e., this:
template <typename enum_type,
typename = is_enum_flags_enum_type_t<enum_type>>
enum_type
operator& (enum_type e1, enum_type e2)
instead of:
template <typename enum_type>
typename enum_flags_type<enum_type>::type
operator& (enum_type e1, enum_type e2)
Note that the static_assert inside operator~() was converted to a
couple overloads (signed vs unsigned), because static_assert is too
late for SFINAE-based tests, which is important for the CHECK_VALID
unit tests.
Tested with gcc {4.8, 7.1, 9.3} and clang {5.0.2, 10.0.0}.

gdb: move regcache::regcaches to regcache.c
I don't really understand why `regcache_thread_ptid_changed` is a static method of `struct regcache` instead of being a static free function in regcache.c. And I don't understand why `current_regcache` is a static member of `struct regcache` instead of being a static global in regcache.c. It's not wrong per-se, but there's no other place where we do it like this in GDB (as far as I remember) and it just exposes things unnecessarily in the .h. Move them to be just static in regcache.c. As a result, registers_changed_ptid doesn't need to be friend of the regcache class anymore. Removing the include of forward_list in regcache.h showed that we were missing an include for it in dwarf2/index-write.c, record-btrace.c and sparc64-tdep.c. gdb/ChangeLog: * regcache.h (class regcache): Remove friend registers_changed_ptid. <regcache_thread_ptid_changed>: Remove. <regcaches>: Remove. * regcache.c (regcache::regcaches): Rename to...

gdb: remove unused fetch_inferior_event and inferior_event_handler parameters
I noticed that fetch_inferior_event receives the client_data parameter from its caller, inferior_event_handler, but doesn't actually need it. This patch removes it. In turn, inferior_event_handler doesn't use its parameter, so remove it too. The `data` argument used when registering remote_async_inferior_event_handler is changed to NULL, to avoid confusion. It could make people think that the value passed is used somewhere, when in fact it's not. gdb/ChangeLog: * inf-loop.c (inferior_event_handler): Remove client_data param. * inf-loop.h (inferior_event_handler): Likewise. * infcmd.c (step_1): Adjust. * infrun.c (proceed): Adjust.

gdb, btrace: forward fetch_registers for unknown threads
In the record-btrace target, while replaying, we can only provide the PC register. The btrace state is stored in the thread_info. So, when trying to determine whether we are currently replaying, GDB calls find_thread_ptid() to obtain the thread_info. It also asserts that we do have a thread_info. For new threads, libthread-db may fetch registers before the thread is known to GDB. In this case, find_thread_ptid() returns nullptr and the assertion fails.

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.

gdb: Add support for tracking the DWARF line table is-stmt field
This commit brings support for the DWARF line table is_stmt field to GDB. The is_stmt field is used by the compiler when a single source line is split into multiple assembler instructions, especially if the assembler instructions are interleaved with instruction from other source lines. The compiler will set the is_stmt flag false from some instructions from the source lines, these instructions are not a good place to insert a breakpoint in order to stop at the source line. Instructions which are marked with the is_stmt flag true are a good place to insert a breakpoint for that source line. Currently GDB ignores all instructions for which is_stmt is false. This is fine in a lot of cases, however, there are some cases where this means the debug experience is not as good as it could be. Consider stopping at a random instruction, currently this instruction will be attributed to the last line table entry before this point for which is_stmt was true - as these are the only line table entries that GDB tracks. This can easily be incorrect in code with even a low level of optimisation. With is_stmt tracking in place, when stopping at a random instruction we now attribute the instruction back to the real source line, even when is_stmt is false for that instruction in the line table. When inserting breakpoints we still select line table entries for which is_stmt is true, so the breakpoint placing behaviour should not change. When stepping though code (at the line level, not the instruction level) we will still stop at instruction where is_stmt is true, I think this is more likely to be the desired behaviour. Instruction stepping is, of course, unchanged, stepping one instruction at a time, but we should now report more accurate line table information with each instruction step. The original motivation for this work was a patch posted by Bernd here: https://sourceware.org/ml/gdb-patches/2019-11/msg00792.html As part of that thread it was suggested that many issues would be resolved if GDB supported line table views, this isn't something I've attempted in this patch, though reading the spec, it seems like this would be a useful feature to support in GDB in the future. The spec is here: http://dwarfstd.org/ShowIssue.php?issue=170427.1 And Bernd gives a brief description of the benefits here: https://sourceware.org/ml/gdb-patches/2020-01/msg00147.html With that all said, I think that there is benefit to having proper is_stmt support regardless of whether we have views support, so I think we should consider getting this in first, and then building view support on top of this. The gdb.cp/step-and-next-inline.exp test is based off a test proposed by Bernd Edlinger in this message: https://sourceware.org/ml/gdb-patches/2019-12/msg00842.html gdb/ChangeLog: * buildsym-legacy.c (record_line): Pass extra parameter to record_line. * buildsym.c (buildsym_compunit::record_line): Take an extra parameter, reduce duplication in the line table, and record the is_stmt flag in the line table. * buildsym.h (buildsym_compunit::record_line): Add extra parameter. * disasm.c (do_mixed_source_and_assembly_deprecated): Ignore non-statement lines. * dwarf2/read.c (dwarf_record_line_1): Add extra parameter, pass this to the symtab builder.

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:
commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
Author: John Baldwin <jhb@FreeBSD.org>
Date: Sat Sep 9 11:02:37 2017 -0700
Remove unnecessary function prototypes.
I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

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.
