Remove get_current_regcache, inlining the call to get_thread_regcache in
callers. When possible, pass the right thread_info object known from
the local context. Otherwise, fall back to passing `inferior_thread ()`.
This makes the reference to global context bubble up one level, a small
step towards the long term goal of reducing the number of references to
global context (or rather, moving those references as close as possible
to the top of the call tree).
No behavior change expected.

I noticed that if GDB is using a remote or extended-remote target,
then, if an inferior call caused a new thread to appear, or for an
existing thread to exit, then these events are not reported to the
user.
The problem is that for these targets GDB relies on a call to
update_thread_list to learn about changes to the inferior's thread
list.
If GDB doesn't pass through the normal stop code then GDB will not
call update_thread_list, and so will not report changes in the thread
list.
This commit adds an additional update_thread_list call, after which
thread events are correctly reported.

gdb: avoid double stop after failed breakpoint condition check
Addressed a problem where two MI stopped events would be reported if a
breakpoint condition failed due to a signal, this commit was a
replacement for this commit:
commit 2e411b8c68eb2b035b31d5b00d940d4be1a0928b
Date: Fri Oct 14 14:53:15 2022 +0100
gdb: don't always print breakpoint location after failed condition check
which solved the two stop problem, but only for the CLI. Before both
of these commits, if a b/p condition failed due to a signal then the
user would see two stops reported, the first at the location where the
signal occurred, and the second at the location of the breakpoint.
By default GDB remains at the location where the signal occurred, so
the second reported stop can be confusing, this is the problem that
commit 2e411b8c68eb tried to solve (for the CLI) and b1c0ab20809a
extended also address the issue for MI too.
However, while working on another patch I realised that there was a
problem with GDB after the above commits. Neither of the above
commits considered 'set unwindonsignal on'. With this setting on,
when an inferior function call fails with a signal GDB will unwind the
stack back to the location where the inferior function call started.
In the b/p case we're looking at, the stop should be reported at the
location of the breakpoint, not at the location where the signal
occurred, and this isn't what happens.
This commit fixes this by ensuring that when unwindonsignal is 'on',
GDB reports a single stop event at the location of the breakpoint,
this fixes things for both CLI and MI.
The function call_thread_fsm::should_notify_stop is called when the
inferior function call completes and GDB is figuring out if the user
should be notified about this stop event by calling normal_stop from
fetch_inferior_event in infrun.c. If normal_stop is called, then this
notification will be for the location where the inferior call stopped,
which will be the location at which the signal occurred.
Prior to this commit, the only time that normal_stop was not called,
was if the inferior function call completed successfully, this was
controlled by ::should_notify_stop, which only turns false when the
inferior function call has completed successfully.
In this commit I have extended the logic in ::should_notify_stop. Now
there are three cases in which ::should_notify_stop will return false,
and we will not announce the first stop (by calling normal_stop).
These three reasons are:
1. If the inferior function call completes successfully, this is
unchanged behaviour,
2. If the inferior function call stopped due to a signal and 'set
unwindonsignal on' is in effect, and
3. If the inferior function call stopped due to an uncaught C++
exception, and 'set unwind-on-terminating-exception on' is in
effect.
However, if we don't call normal_stop then we need to call
async_enable_stdin in call_thread_fsm::should_stop. Prior to this
commit this was only done for the case where the inferior function
call completed successfully.
In this commit I now call ::should_notify_stop and use this to
determine if we need to call async_enable_stdin. With this done we
now call async_enable_stdin for each of the three cases listed above,
which means that GDB will exit wait_sync_command_done correctly (see
run_inferior_call in infcall.c).
With these two changes the problem is mostly resolved. However, the
solution isn't ideal, we've still lost some information.
Here is how GDB 13.1 behaves, this is before commits b1c0ab20809a and
2e411b8c68eb:
$ gdb -q /tmp/mi-condbreak-fail \
-ex 'set unwindonsignal on' \
-ex 'break 30 if (cond_fail())' \
-ex 'run'
Reading symbols from /tmp/mi-condbreak-fail...
Breakpoint 1 at 0x40111e: file /tmp/mi-condbreak-fail.c, line 30.

Program received signal SIGSEGV, Segmentation fault.
0x0000000000401116 in cond_fail () at /tmp/mi-condbreak-fail.c:24
24 return *p; /* Crash here. */
Error in testing breakpoint condition:
The program being debugged was signaled while in a function called from GDB.
GDB has restored the context to what it was before the call.
To change this behavior use "set unwindonsignal off".
Evaluation of the expression containing the function
(cond_fail) will be abandoned.
Breakpoint 1, foo () at /tmp/mi-condbreak-fail.c:30
30 global_counter += 1; /* Set breakpoint here. */
(gdb)
In this state we see two stop notifications, the first is where the
signal occurred, while the second is where the breakpoint is located.
As GDB has unwound the stack (thanks to unwindonsignal) the second
stop notification reflects where the inferior is actually located.
Then after commits b1c0ab20809a and 2e411b8c68eb the behaviour changed
to this:
$ gdb -q /tmp/mi-condbreak-fail \
-ex 'set unwindonsignal on' \
-ex 'break 30 if (cond_fail())' \
-ex 'run'
Reading symbols from /tmp/mi-condbreak-fail...

0x0000000000401116 in cond_fail () at /tmp/mi-condbreak-fail.c:24
24 return *p; /* Crash here. */
Error in testing condition for breakpoint 1:
The program being debugged was signaled while in a function called from GDB.
GDB has restored the context to what it was before the call.
To change this behavior use "set unwindonsignal off".
Evaluation of the expression containing the function

(gdb) bt 1
#0 foo () at /tmp/mi-condbreak-fail.c:30
(More stack frames follow...)
(gdb)
This is the broken state. GDB is reports the SIGSEGV location, but
not the unwound breakpoint location. The final 'bt 1' shows that the
inferior is not located in cond_fail, which is the only location GDB
reported, so this is clearly wrong.
After implementing the fixes described above we now get this
behaviour:
$ gdb -q /tmp/mi-condbreak-fail \
-ex 'set unwindonsignal on' \
-ex 'break 30 if (cond_fail())' \
-ex 'run'
Reading symbols from /tmp/mi-condbreak-fail...

(cond_fail) will be abandoned.
Breakpoint 1, foo () at /tmp/mi-condbreak-fail.c:30
30 global_counter += 1; /* Set breakpoint here. */
(gdb)
This is better. GDB now reports a single stop at the location of the
breakpoint, which is where the inferior is actually located. However,
by removing the first stop notification we have lost some potentially
useful information about which signal caused the inferior to stop.
To address this I've reworked the message that is printed to include
the signal information. GDB now reports this:
$ gdb -q /tmp/mi-condbreak-fail \
-ex 'set unwindonsignal on' \
-ex 'break 30 if (cond_fail())' \
-ex 'run'
Reading symbols from /tmp/mi-condbreak-fail...

Error in testing condition for breakpoint 1:

Breakpoint 1, foo () at /tmp/mi-condbreak-fail.c:30
30 global_counter += 1; /* Set breakpoint here. */
(gdb)
This is better, the user now sees a single stop notification at the
correct location, and the error message describes which signal caused
the inferior function call to stop.
However, we have lost the information about where the signal
occurred. I did consider trying to include this information in the
error message, but, in the end, I opted not too. I wasn't sure it was
worth the effort. If the user has selected to unwind on signal, then
surely this implies they maybe aren't interested in debugging failed
inferior calls, so, hopefully, just knowing the signal name will be
enough. I figure we can always add this information in later if
there's a demand for it.

While looking at a bug, I noticed what I think is an off-by-one
mistake in a call to vector::reserve. This code:
new_args.reserve (args.size ());
new_args.push_back
(value_from_pointer (lookup_pointer_type (values_type), struct_addr));
new_args.insert (new_args.end (), args.begin (), args.end ());
... reserves 'size()' entries, but then proceeds to push one extra
one.
This shouldn't have any really bad effects, as insert will grow the
vector. Still, it seems better to use the correct size if we're going
to bother calling reserve.

commit 2e411b8c68eb2b035b31d5b00d940d4be1a0928b
Date: Fri Oct 14 14:53:15 2022 +0100
gdb: don't always print breakpoint location after failed condition check
and is a result of feedback received here[1].
The original commit addressed a problem where, if a breakpoint
condition included an inferior function call, and if the inferior
function call failed, then GDB would announce the stop twice. Here's
an example of GDB's output before the above commit that shows the
problem being addressed:
(gdb) break foo if (some_func ())
Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
(gdb) r

Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5

(gdb)
The original commit addressed this issue in breakpoint.c, by spotting
that the $pc had changed while evaluating the breakpoint condition,
and inferring from this that GDB must have stopped elsewhere.
However, the way in which the original commit suppressed the second
stop announcement was to set bpstat::print to true -- this tells GDB
not to print the frame during the stop announcement, and for the CLI
this is fine, however, it was pointed out that for the MI this still
isn't really enough. Below is an example from an MI session after the
above commit was applied, this shows the problem with the above

*stopped
(gdb)
Notice that we still see two '*stopped' lines, the first includes the
full frame information, while the second has no frame information,
this is a result of bpstat::print having been set. Ideally, the
second '*stopped' line should not be present.
By setting bpstat::print I was addressing the problem too late, this
flag really only changes how interp::on_normal_stop prints the stop
event, and interp::on_normal_stop is called (indirectly) from the
normal_stop function in infrun.c. A better solution is to avoid
calling normal_stop at all for the stops which should not be reported
to the user, and this is what I do in this commit.
This commit has 3 parts:
1. In breakpoint.c, revert the above commit,
2. In fetch_inferior_event (infrun.c), capture the stop-id before
calling handle_inferior_event. If, after calling
handle_inferior_event, the stop-id has changed, then this indicates
that somewhere within handle_inferior_event, a stop was announced to
the user. If this is the case then GDB should not call normal_stop,
and we should rely on whoever announced the stop to ensure that we
are in a PROMPT_NEEDED state, which means the prompt will be
displayed once fetch_inferior_event returns. And,
3. In infcall.c, do two things:
(a) In run_inferior_call, after making the inferior call, ensure
that either async_disable_stdin or async_enable_stdin is called
to put the prompt state, and stdin handling into the correct
state based on whether the inferior call completed successfully
or not, and
(b) In call_thread_fsm::should_stop, call async_enable_stdin
rather than changing the prompt state directly. This isn't
strictly necessary, but helped me understand this code more.
This async_enable_stdin call is only reached if normal_stop is
not going to be called, and replaces the async_enable_stdin call
that exists in normal_stop. Though we could just adjust the
prompt state if felt (to me) much easier to understand when I
could see this call and the corresponding call in normal_stop.
With these changes in place now, when the inferior call (from the
breakpoint condition) fails, infcall.c leaves the prompt state as
PROMPT_NEEDED, and leaves stdin registered with the event loop.
Back in fetch_inferior_event GDB notices that the stop-id has changed
and so avoids calling normal_stop.
And on return from fetch_inferior_event GDB will display the prompt
and handle input from stdin.
As normal_stop is not called the MI problem is solved, and the test
added in the earlier mentioned commit still passes just fine, so the
CLI has not regressed.

Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5

(gdb)
Notice that this line:
Program received signal SIGSEGV, Segmentation fault.
Appears twice in the output. The first time is followed by the
current location. The second time is a little odd, why do we print
that?
Printing that line is controlled, in part, by a global variable,
stopped_by_random_signal. This variable is reset to zero in
handle_signal_stop, and is set if/when GDB figures out that the
inferior stopped due to some random signal.
The problem is, in our case, GDB first stops at the breakpoint for
foo, and enters handle_signal_stop and the stopped_by_random_signal
global is reset to 0.
Later within handle_signal_stop GDB calls bpstat_stop_status, it is
within this function (via bpstat_check_breakpoint_conditions) that the
breakpoint condition is checked, and, we end up calling the inferior
function (some_func in our example above).
In our case above the thread performing the inferior function call
segfaults in some_func. GDB catches the SIGSEGV and handles the stop,
this causes us to reenter handle_signal_stop. The global variable
stopped_by_random_signal is updated, this time it is set to true
because the thread stopped due to SIGSEGV. As a result of this we
print the first instance of the line (as seen above in the example).
Finally we unwind GDB's call stack, the inferior function call is
complete, and we return to the original handle_signal_stop. However,
the stopped_by_random_signal global is still carrying the value as
computed for the inferior function call's stop, which is why we now
print a second instance of the line, as seen in the example.
To prevent this, I propose adding a scoped_restore before we start an
inferior function call. This will save and restore the global
stopped_by_random_signal value.
With this done, the output from our example is now this:
(gdb) list some_func
1 int
2 some_func ()
3 {
4 int *p = 0;
5 return *p;
6 }
7
8 void
9 foo ()
10 {
(gdb) break foo if (some_func ())

(gdb)
We now only see the 'Program received signal SIGSEGV, ...' line once,
which I think makes more sense.
Finally, I'm aware that the last few lines, that report the stop as
being at 'Breakpoint 1', when this is not where the thread is actually
located anymore, is not great. I'll address that in the next commit.

This is the second step of making frame_info_ptr automatic, reinflate on
demand whenever trying to obtain the wrapper frame_info pointer, either
through the get method or operator->. Make the reinflate method
private, it is used as a convenience method in those two.
Add an "is_null" method, because it is often needed to know whether the
frame_info_ptr wraps an frame_info or is empty.
Make m_ptr mutable, so that it's possible to reinflate const
frame_info_ptr objects. Whether m_ptr is nullptr or not does not change
the logical state of the object, because we re-create it on demand. I
believe this is the right use case for mutable.

PR record/29927 - reverse-finish requires two reverse next instructions to
reach previous source line
Currently on X86, when executing the finish command in reverse, gdb does a
single step from the first instruction in the callee to get back to the
caller. GDB stops on the last instruction in the source code line where
the call was made. When stopped at the last instruction of the source code
line, a reverse next or step command will stop at the first instruction
of the same source code line thus requiring two step/next commands to
reach the previous source code line. It should only require one step/next
command to reach the previous source code line.
By contrast, a reverse next or step command from the first line in a
function stops at the first instruction in the source code line where the
call was made.
This patch fixes the reverse finish command so it will stop at the first
instruction of the source line where the function call was made. The
behavior on X86 for the reverse-finish command now matches doing a
reverse-next from the beginning of the function.
The proceed_to_finish flag in struct thread_control_state is no longer
used. This patch removes the declaration, initialization and setting of
the flag.
This patch requires a number of regression tests to be updated. Test
gdb.mi/mi-reverse.exp no longer needs to execute two steps to get to the
previous line. The gdb output for tests gdb.reverse/until-precsave.exp
and gdb.reverse/until-reverse.exp changed slightly. The expected result in
tests gdb.reverse/amd64-failcall-reverse.exp and
gdb.reverse/singlejmp-reverse.exp are updated to the correct expected
result.
This patch adds a new test gdb.reverse/finish-reverse-next.exp to test the
reverse-finish command when returning from the entry point and from the
body of the function.
The step_until proceedure in test gdb.reverse/step-indirect-call-thunk.exp
was moved to lib/gdb.exp and renamed cmd_until.
The patch has been tested on X86 and PowerPC to verify no additional
regression failures occured.

get_call_return_value can handle RETURN_VALUE_STRUCT_CONVENTION,
because the call is completely managed by gdb. However, it does not
handle variably-sized types correctly. The simplest way to fix this
is to use value_at_non_lval, which does type resolution.
|
|
The gdbarch "return_value" can't correctly handle variably-sized
types. The problem here is that the TYPE_LENGTH of such a type is 0,
until the type is resolved, which requires reading memory. However,
gdbarch_return_value only accepts a buffer as an out parameter.
Fixing this requires letting the implementation of the gdbarch method
resolve the type and return a value -- that is, both the contents and
the new type.
After an attempt at this, I realized I wouldn't be able to correctly
update all implementations (there are ~80) of this method. So,
instead, this patch adds a new method that falls back to the current
method, and it updates gdb to only call the new method. This way it's
possible to incrementally convert the architectures that I am able to
test.

With a simple test-case:
...
$ cat test.c
char *p = "a";
int main (void) {
return strlen (p);
}
$ gcc -g test.c
...
we run into this segfault:
...
$ gdb -q -batch a.out -ex start -ex "p strlen (p)"
Temporary breakpoint 1 at 0x1151: file test.c, line 4.
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Temporary breakpoint 1, main () at test.c:4
4 return strlen (p);
Fatal signal: Segmentation fault
...
The strlen is an ifunc, and consequently during the call to
call_function_by_hand_dummy for "p strlen (p)" another call
to call_function_by_hand_dummy is used to resolve the ifunc.
This invalidates the get_current_frame () result in the outer call.
Fix this by using prepare_reinflate and reinflate.
Note that this series (
https://inbox.sourceware.org/gdb-patches/20221214033441.499512-1-simon.marchi@polymtl.ca/ )

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.

Add two new commands:
set debug infcall on|off
show debug infcall
These enable some new debugging related to when GDB makes inferior
function calls. I've added some basic debugging for what I think are
the major steps in the inferior function call process, but I'm sure we
might want to add more later.

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

that's only active for ada:

This patch removes ui_register_input_event_handler and
ui_unregister_input_event_handler, replacing them with methods on
'ui'. It also changes gdb to use these methods everywhere, rather
than sometimes reaching in to the ui to manage the file descriptor
directly.

In passing I noticed that there are three local variables in
run_inferior_call that are used to save, and then restore some state,
I think these could all be replaced with a RAII style scoped_restore
instead.
Of the three locals that I've changed, the only one that I believe is
now restored in a different location is ui::async, before this commit
the async field was restored after a call to either delete_file_handle
or ui_register_input_event_handler, and after this commit, the field
is restored before these calls. However, I don't believe that either
of these functions depend on the value of the async field, so I
believe the commit is fine.

It is possible for a compiler to optimize a function in a such ways that
the function does not follow the calling convention of the target. In
such situation, the compiler can use the DW_AT_calling_convention
attribute with the value DW_CC_nocall to tell the debugger that it is
unsafe to call the function. The DWARF5 standard states, in 3.3.1.1:
> If the value of the calling convention attribute is the constant
> DW_CC_nocall, the subroutine does not obey standard calling
> conventions, and it may not be safe for the debugger to call this
> subroutine.
Non standard calling convention can affect GDB's assumptions in multiple
ways, including how arguments are passed to the function, how values are
returned, and so on. For this reason, it is unsafe for GDB to try to do
the following operations on a function with marked with DW_CC_nocall:
- call / print an expression requiring the function to be evaluated,
- inspect the value a function returns using the 'finish' command,
- force the value returned by a function using the 'return' command.
This patch ensures that if a command which relies on GDB's knowledge of
the target's calling convention is used on a function marked nocall, GDB
prints an appropriate message to the user and does not proceed with the
operation which is unreliable.
Note that it is still possible for someone to use a vendor specific
value for the DW_AT_calling_convention attribute for example to indicate
the use of an alternative calling convention. This commit does not
prevent this, and target dependent code can be adjusted if one wanted to
support multiple calling conventions.

While working on function calls, I realized that the thread_fsm member
of struct thread_info is a raw pointer to a resource it owns. This
commit changes the type of the thread_fsm member to a std::unique_ptr in
order to signify this ownership relationship and slightly ease resource
management (no need to manually call delete).
To ensure consistent use, the field is made a private member
(m_thread_fsm). The setter method (set_thread_fsm) can then check
that it is incorrect to associate a FSM to a thread_info object if
another one is already in place. This is ensured by an assertion.
The function run_inferior_call takes an argument as a pointer to a
call_thread_fsm and installs it in it in a thread_info instance. Also
change this function's signature to accept a unique_ptr in order to
signify that the ownership of the call_thread_fsm is transferred during
the call.
No user visible change expected after this commit.

The bug fixed by this [1] patch was caused by an out-of-bounds access to
a value's content. The code gets the value's content (just a pointer)
and then indexes it with a non-sensical index.
This made me think of changing functions that return value contents to
return array_views instead of a plain pointer. This has the advantage
that when GDB is built with _GLIBCXX_DEBUG, accesses to the array_view
are checked, making bugs more apparent / easier to find.
This patch changes the return types of these functions, and updates
callers to call .data() on the result, meaning it's not changing
anything in practice. Additional work will be needed (which can be done
little by little) to make callers propagate the use of array_view and
reap the benefits.

Date: Mon Sep 4 20:21:13 2017 +0100
Stop assuming no-debug-info functions return int
A new if case was added to call_function_by_hand_dummy to decide if a
function should be considered prototyped or not. Previously the code
was structured like this:
if (COND_1)
ACTION_1
else if (COND_2)
ACTION_2
else
ACTION_3
With the new block the code now looks like this:
if (COND_1)
ACTION_1
if (NEW_COND)
NEW_ACTION
else if (COND_2)
ACTION_2
else
ACTION_3
Notice the new block was added as and 'if' not 'else if'. I'm running
into a case where GDB executes ACTION_1 and then ACTION_2. Prior to
the above commit GDB would only have executed ACTION_1.
The actions in the code in question are trying to figure out if a
function should be considered prototyped or not. When a function is
not prototyped some arguments will be coerced, e.g. floats to doubles.
The COND_1 / ACTION_1 are a very broad, any member function should be
considered prototyped, however, after the above patch GDB is now
executing the later ACTION_2 which checks to see if the function's
type has the 'prototyped' flag set - this is not the case for the
member functions I'm testing, and so GDB treats the function as
unprototyped and casts the float argument to a double.
I believe that adding the new check as 'if' rather than 'else if' was
a mistake, and so in this commit I add in the missing 'else'.

* infcall.c (call_function_by_hand_dummy): Add missing 'else' when

The current_top_target function is a hidden dependency on the current
inferior. Since I'd like to slowly move towards reducing our dependency
on the global current state, remove this function and make callers use

making those callers use the inferior from their context, rather than
refer to the global current inferior.

current inferior instead.

Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). 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).

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.
