This function is just a wrapper around the current inferior's gdbarch.
I find that having that wrapper just obscures where the arch is coming
from, and that it's often used as "I don't know which arch to use so
I'll use this magical target_gdbarch function that gets me an arch" when
the arch should in fact come from something in the context (a thread,
objfile, symbol, etc). I think that removing it and inlining
`current_inferior ()->arch ()` everywhere will make it a bit clearer
where that arch comes from and will trigger people into reflecting
whether this is the right place to get the arch or not.

The new_objfile observer is currently used to indicate both when a new
objfile is added to program space (when passed non-nullptr) and when all
objfiles of a program space were just removed (when passed nullptr).
I think this is confusing (and Andrew apparently thinks so too [1]).
Add a new "all_objfiles_removed" observer to remove the second role from
"new_objfile".
Some existing users of new_objfile do nothing if the passed objfile is
nullptr. For them, we can simply drop the nullptr check. For others,
add a new all_objfiles_removed callback, and refactor things a bit to
keep the existing behavior as much as possible.
Some callbacks relied on current_program_space, and following
the refactoring now use either objfile->pspace or the pspace passed to
all_objfiles_removed. I think this should be relatively safe, and in
general a step in the right direction.
On the notify side, I found only one call site to change from
new_objfile to all_objfiles_removed, in clear_symtab_users. It is not
entirely clear to me that this is entirely correct. clear_symtab_users
appears to be called in spots that don't remove all objfiles
(functions finish_new_objfile, remove_symbol_file_command, reread_symbols,
do_module_cleanups). But I think that this patch at least makes the
current code clearer.

In a recent commit the signature of the scoped_restore_current_inferior_for_memory function was changed and in AIX we did not update the same.
This patch updates it in aix-thread.c file fixed the break and the thread debugging works alright as a result.
|
|
This changes add_thread_with_info to accept a unique_ptr, making it
clear that it takes ownership of the passed-in pointer.
I can't test the AIX or Darwin changes, but I think they are
relatively obvious.

This introduces a new class,
scoped_restore_current_inferior_for_memory, and arranges to use it in
a few places. This class is intended to handle setting up and
restoring the various globals that are needed to read or write memory
-- but without invalidating the frame cache.
I wasn't able to test the change to aix-thread.c.

In AIX if there is a main and a thread created from it , then once the
program completed execution and goes to pd_disable () inferior_ptid
had pid 0 leading to an assertion failure while finding the thread's data
in aix-thread.c file.
This patch is a fix for the same.

AIX now supports vector register contents debugging for both VMX
VSX registers.
|
|
Multi-threaded debugging using the libpthdebug debug interface
is currently broken due to multiple issues.
When debugging a single inferior, we were getting assertion
failures in get_aix_thread_info as no tp->priv structure was
allocated for the main thread.
We fixed this by switching the main
thread from a (pid, 0, 0) ptid_t to a (pid, 0, tid) ptid_t and
allocaing the tp->priv structure in sync_threadlists.
As a result, the switch_to_thread call in pdc_read_data could
now fail since the main thread no longer uses (pid, 0, 0).
So we replaced the call by only switching inferior_ptid, the current
inferior, and the current address space (like proc-service.c).
Add similar switching to pdc_write_data where it was missing
completely.
When debugging multiple inferiors, an additional set of
problems prevented correct multi-threaded debugging:
First of all, aix-thread.c used to have a number of global
variables holding per-inferior information.
We switched hese
to a per-inferior data structure instead.
Also, sync_threadlists was getting confused as we were
comparing the list of threads returned by libpthdebug
for *one* process with GDB's list of threads for *all*
processes. Now we only use he GDB threads of the current
inferior instead.
We also skip calling pd_activate
from pd_enable if that in_initial_library_scan flag is
true for the current inferior.
Finally, the presence of the thread library in any but
the first inferior was not correctly detected due to a
bug in solib-aix.c, where the BFD file name for shared
library members was changed when the library was loaded
for the first time, which caused the library to no longer
be recognized by name when loaded a second time.

In AIX multiple threads were not added. This patch is a fix for the same
When we create a pthread debug session we have callbacks to read
symbols and memory. One of those call backs is pdc_read_data.
Before we come into aix-thread wait() we switch to no thread and
therefore the current thread is null.
When we get into pdc_read_data we have a dependency that we need to
be in the correct current thread that has caused an event of new
thread, inorder to read memory.
Hence we switch to the correct thread.
This is done by passing the pid in the pthdb_user_t user_current_pid
parameter in every call back.

I built GDB for all targets on a x86-64/GNU-Linux system, and
then (accidentally) passed GDB a RISC-V binary, and asked GDB to "run"
the binary on the native target. I got this error:
(gdb) show architecture
The target architecture is set to "auto" (currently "i386").
(gdb) file /tmp/hello.rv32.exe
Reading symbols from /tmp/hello.rv32.exe...
(gdb) show architecture
The target architecture is set to "auto" (currently "riscv:rv32").
(gdb) run
Starting program: /tmp/hello.rv32.exe
../../src/gdb/i387-tdep.c:596: internal-error: i387_supply_fxsave: Assertion `tdep->st0_regnum >= I386_ST0_REGNUM' failed.
What's going on here is this; initially the architecture is i386, this
is based on the default architecture, which is set based on the native
target. After loading the RISC-V executable the architecture of the
current inferior is updated based on the architecture of the
executable.
When we "run", GDB does a fork & exec, with the inferior being
controlled through ptrace. GDB sees an initial stop from the inferior
as soon as the inferior comes to life. In response to this stop GDB
ends up calling save_stop_reason (linux-nat.c), which ends up trying
to read register from the inferior, to do this we end up calling
target_ops::fetch_registers, which, for the x86-64 native target,
calls amd64_linux_nat_target::fetch_registers.
After this I eventually end up in i387_supply_fxsave, different x86
based targets will end in different functions to fetch registers, but
it doesn't really matter which function we end up in, the problem is
this line, which is repeated in many places:
i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
The problem here is that the ARCH in this line comes from the current
inferior, which, as we discussed above, will be a RISC-V gdbarch, the
tdep field will actually be of type riscv_gdbarch_tdep, not
i386_gdbarch_tdep. After this cast we are relying on undefined
behaviour, in my case I happen to trigger an assert, but this might
not always be the case.
The thing I tried that exposed this problem was of course, trying to
start an executable of the wrong architecture on a native target. I
don't think that the correct solution for this problem is to detect,
at the point of cast, that the gdbarch_tdep object is of the wrong
type, but, I did wonder, is there a way that we could protect
ourselves from incorrectly casting the gdbarch_tdep object?
I think that there is something we can do here, and this commit is the
first step in that direction, though no actual check is added by this
commit.
This commit can be split into two parts:
(1) In gdbarch.h and arch-utils.c. In these files I have modified
gdbarch_tdep (the function) so that it now takes a template argument,
like this:
template<typename TDepType>
static inline TDepType *
gdbarch_tdep (struct gdbarch *gdbarch)
{
struct gdbarch_tdep *tdep = gdbarch_tdep_1 (gdbarch);
return static_cast<TDepType *> (tdep);
}
After this change we are no better protected, but the cast is now
done within the gdbarch_tdep function rather than at the call sites,
this leads to the second, much larger change in this commit,
(2) Everywhere gdbarch_tdep is called, we make changes like this:
- i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
+ i386_gdbarch_tdep *tdep = gdbarch_tdep<i386_gdbarch_tdep> (arch);
There should be no functional change after this commit.
In the next commit I will build on this change to add an assertion in
gdbarch_tdep that checks we are casting to the correct type.

../../src/binutils-gdb/gdb/inferior.c:304: internal-error: find_inferior_pid: Assertion `pid != 0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
This is due to some bit-rot in the AIX port, still relying on the entry
value of inferior_ptid in the wait methods.
Problem #1 is in rs6000_nat_target::wait, here:
/* Ignore terminated detached child processes. */
if (!WIFSTOPPED (status) && pid != inferior_ptid.pid ())
pid = -1;
At this point, waitpid has returned an "exited" status for some pid, so
pid is non-zero. Since inferior_ptid is set to null_ptid on entry, the
pid returned by wait is not equal to `inferior_ptid.pid ()`, so we reset
pid to -1 and go to waiting again. Since there are not more children to
wait for, waitpid then returns -1 so we get here:
if (pid == -1)
{
gdb_printf (gdb_stderr,
_("Child process unexpectedly missing: %s.\n"),
safe_strerror (save_errno));
/* Claim it exited with unknown signal. */
ourstatus->set_signalled (GDB_SIGNAL_UNKNOWN);
return inferior_ptid;
}
We therefore return a "signalled" status with a null_ptid (again,
inferior_ptid is null_ptid). This confuses infrun, because if the
target returns a "signalled" status, it should be coupled with a ptid
for an inferior that exists.
So, the first step is to fix the snippets above to not use
inferior_ptid. In the first snippet, use find_inferior_pid to see if
we know the event process. If there is no inferior with that pid, we
assume it's a detached child process to we ignore the event. That
should be enough to fix the problem, because it should make it so we
won't go into the second snippet. But still, fix the second snippet to
return an "ignore" status. This is copied from inf_ptrace_target::wait,
which is where rs6000_nat_target::wait appears to be copied from in the
first place.
These changes, are not sufficient, as the aix_thread_target, which sits
on top of rs6000_nat_target, also relies on inferior_ptid.
aix_thread_target::wait, by calling pd_update, assumes that
rs6000_nat_target has set inferior_ptid to the appropriate value (the
ptid of the event thread), but that's not the case. pd_update
returns inferior_ptid - null_ptid - and therefore
aix_thread_target::wait returns null_ptid too, and we still hit the
assert shown above.
Fix this by changing pd_activate, pd_update, sync_threadlists and
get_signaled_thread to all avoid using inferior_ptid. Instead, they
accept as a parameter the pid of the process we are working on.
With this patch, I am able to run the program to completion:

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).

get_ada_task_ptid currently takes a 'long' as its 'thread' parameter
type. However, on some platforms this is actually a pointer, and
using 'long' can sometimes end up with the value being sign-extended.
This sign extension can cause problems later, if the tid is then later
used as an address again.
This patch changes the parameter type to ULONGEST and updates all the
uses. This approach preserves sign extension on the targets where it
is apparently intended, while avoiding it on others.

unpush_target unpushes the passed-in target from the current inferior's
target stack. Calling it is therefore an implicit dependency on the
current global inferior. Remove that function and make the callers use
the inferior::unpush_target method directly. This sometimes allows
using the inferior from the context rather than the global current
inferior.
target_unpusher::operator() now needs to be implemented in target.c,
otherwise target.h and inferior.h both need to include each other, and
that wouldn't work.

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 think it would make sense for the inferior_created observable to say
which inferior is being dealt with, rather than relying on it being the
current inferior.
This patch adds an inferior parameter to inferior_created, but does not
change the callbacks to use it.
gdb/ChangeLog:
* aix-thread.c (aix_thread_inferior_created): Add inferior
parameter.
* bsd-uthread.c (bsd_uthread_inferior_created): Likewise.
* dummy-frame.c (cleanup_dummy_frames): Likewise.

I just noticed that in a7aba2668a7b ("gdb: remove arguments from
inferior_created observable"), I forgot to update
aix_thread_inferior_created and procfs_inferior_created, which are in
files I can't compile.
Remove the parameters from aix_thread_inferior_created. And simply
remove procfs_inferior_created, since it's empty anyway.
gdb/ChangeLog:
* aix-thread.c (aix_thread_inferior_created): Remove parameters.
* procfs.c (procfs_inferior_created): Remove.
(_initialize_procfs): Don't register procfs_inferior_created.

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. I don't think this patch should go in before the
release branch is made.

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.

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.

Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues
pointed out.

Currently the target pid_to_str method returns a const char *, so many
implementations have a static buffer that they update. This patch
changes these methods to return a std::string instead. I think this
is cleaner and avoids possible gotchas when calling pid_to_str on
different ptids in a single statement. (Though no such calls exist
currently.)
This also updates various helper functions, and the gdbarch pid_to_str
methods.
I also made a best effort to fix all the callers, but I can't build
some of the *-nat.c files.
Tested by the buildbot.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.

Given that a target's stratum is a property of the type, and not of an
instance of the type, get rid of to_stratum data field and replace it
with a virtual method.
I.e., when we have e.g., 10 target remote instances active, there's no
need for each of the instances to have their own to_stratum copy.

Commit 00431a78b28f ("Use thread_info and inferior pointers more
throughout") missed updating some callers, like e.g.,:
gdb/remote-sim.c: In member function 'virtual void gdbsim_target::mourn_inferior()':
gdb/remote-sim.c:1198:50: error: cannot convert 'ptid_t' to 'thread_info*' for argument '1' to 'void delete_thread_silent(thread_info*)'
delete_thread_silent (sim_data->remote_sim_ptid);
gdb/mygit/src/gdb/procfs.c: In member function ‘virtual void procfs_target::detach(inferior*, int)’:
gdb/mygit/src/gdb/procfs.c:1931:23: error: invalid conversion from ‘int’ to ‘inferior*’ [-fpermissive]
detach_inferior (pid);
^
In file included from gdb/mygit/src/gdb/procfs.c:24:0:
gdb/mygit/src/gdb/inferior.h:476:13: note: initializing argument 1 of ‘void detach_inferior(inferior*)’
etc.
This fixes it.
The delete_thread_silent calls in both go32-nat.c and remote-sim.c are
unnecessary because generic_mourn_inferior calls exit_inferior, which
deletes the inferior's threads.
gdb/ChangeLog:
2018-06-25 Pedro Alves <palves@redhat.com>
* windows-nat.c (windows_delete_thread): Use find_thread_ptid and
pass thread_info pointer to delete_thread.
(windows_nat_target::detach): Pass inferior pointer to
detach_inferior.
* aix-thread.c (sync_threadlists): Pass thread_info pointer to
delete_thread.
* bsd-kvm.c (bsd_kvm_target::close): Use discard_all_inferiors.
* darwin-nat.c (darwin_check_new_threads): Use find_thread_ptid
and pass a thread_info pointer to delete_thread.
* fbsd-nat.c (fbsd_nat_target::wait): Use find_thread_ptid and
pass thread_info pointer to delete_thread.
* go32-nat.c (go32_nat_target::mourn_inferior): Remove
delete_thread_silent call.
* procfs.c (procfs_target::detach): Pass inferior pointer to
detach_inferior.
(procfs_target::wait): Pass thread_info pointer to delete_thread.
* remote-sim.c (gdbsim_target::mourn_inferior): Remove
delete_thread_silent call.
* windows-nat.c (windows_delete_thread): Use find_thread_ptid and
pass thread_info pointer to delete_thread.
(windows_nat_target::detach): Pass inferior pointer to
delete_inferior.
