Switch thread_info::resumed to bool (thread_info::executing already is a bool),
and try to change everything more or less related to that to consistently use
true/false instead of 1/0.
gdb/ChangeLog:
* fork-child.c (gdb_startup_inferior): Use bool instead of int.
* gdbthread.h (class thread_info) <resumed>: Likewise.
* infrun.c (resume_1): Likewise.
(proceed): Likewise.

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

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.

With the multi-target work, each inferior will have its own target
stack, so to call a target method, we'll need to make sure that the
inferior in question is the current one, otherwise target->beneath()
calls will find the target beneath in the wrong inferior.
In some places, it's much more convenient to be able to check whether
an inferior has execution without having to switch to it in order to
call target_has_execution on the right inferior/target stack, to avoid
side effects with switching inferior/thread/program space.
The current target_ops::has_execution method takes a ptid_t as
parameter, which, in a multi-target world, isn't sufficient to
identify the target. This patch prepares to address that, by changing
the parameter to an inferior pointer instead. From the inferior,
we'll be able to query its target stack to tell which target is
beneath.
Also adds a new inferior::has_execution() method to make callers a bit
more natural to read.

Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1765117
A segfault can happen in a specific scenario when using TUI + a
corefile, as explained in the bug mentioned above. The problem
happens when opening a corefile on GDB:
$ gdb ./core program
entering TUI (C-x a), and then issuing a "run" command. GDB segfaults
with the following stack trace:

...
The problem happens because 'tui_locator_window::make_status_line'
needs the value of 'target_shortname' in order to update the status
line. 'target_shortname' is a macro which expands to:
#define target_shortname (current_top_target ()->shortname ())
and, in our scenario, 'current_top_target ()' returns NULL, which
obviously causes a segfault. But why does it return NULL, since,
according to its comment on target.h, it should never do that?
What is happening is that we're being caught in the middle of a
"target switch". We had the 'core_target' on top, because we were
inspecting a corefile, but when the user decided to invoke "run" GDB
had to actually create the inferior, which ends up detecting that we
have a target already, and tries to close it (from target.c):
/* See target.h. */
void
target_stack::push (target_ops *t)
{
/* If there's already a target at this stratum, remove it. */
strata stratum = t->stratum ();
if (m_stack[stratum] != NULL)
{
target_ops *prev = m_stack[stratum];
m_stack[stratum] = NULL;
target_close (prev); // <-- here
}
...
When the current target ('core_target') is being closed, it checks for
possible observers registered with it and calls them. TUI is one of
those observers, it gets called, tries to update the status line, and
GDB crashes.
The real problem is that we are clearing 'm_stack[stratum]', but
forgetting to adjust 'm_top'. Interestingly, this scenario is covered
in 'target_stack::unpush', but Pedro said he forgot to call it here..
The fix, therefore, is to call '::unpush' if there's a target on the
stack.
This patch has been tested on the Buildbot and no regressions have
been found. I'm also submitting a testcase for it.

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

This replaces uses of field_fmt with a "%s" format string to use
field_string instead. Also, one use of "%9lx" is replaced with a call
to phex_nz; the '9' is dropped as it is implicit in the field width.

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

I noticed that target_ops::follow_exec took a "char *" parameter,
where "const char *" would be more correct. This patch changes this
(and related functions) to be constified.
Tested by rebuilding.

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

This renames the gdb exception types. The old types were only needed
due to the macros in common-exception.h that are now gone.
The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

This changes the exception's "message" member to be a shared_ptr
wrapping a std::string. This allows removing the stack of exception
messages, because now exceptions will self-destruct when needed. This
also adds a noexcept copy constructor and operator= to gdb_exception,
plus a "what" method.

Commit 799efbe8e01ab8292c01f46ac59a6fb2349d4535 was supposed to fix
the below leak. However, for this fix to work, it is critical to
save the ptid before detach.
This commit (pushed as OBVIOUS, as the change was already reviewed/approved)
saves the ptid before the detach, as in the original reviewed patch
(see https://sourceware.org/ml/gdb-patches/2019-02/msg00263.html).
Re-tested on debian/amd64, natively and under valgrind.

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.

Permit TLS variable addresses to be resolved purely by an ABI rather
than requiring a target method. This doesn't try the target method if
the ABI function is present (even if the ABI function fails) to
simplify error handling.
gdb/ChangeLog:
* gdbarch.sh (get_thread_local_address): New method.
* gdbarch.h, gdbarch.c: Regenerate.
* target.c (target_translate_tls_address): Use
gdbarch_get_thread_local_address if present instead of
target::get_thread_local_address.

While debugging gdb, I printed the target stack and got:
(top-gdb) p g_target_stack
$10 = {
m_top = thread_stratum,
m_stack = {0x142b0b0, 0x13da600 <exec_ops>, 0x1c70690, 0x13d63b0 <ravenscar_ops>, 0x0, 0x0, 0x0}
}
(This is clearly from before the change to make ravenscar
multi-target-capable.)
Here, 0x142b0b0 is the singleton dummy target. It seems to me that
since this is always a singleton, it would be a bit nicer if it were a
global, so that it would be noted in the above.
This patch implements this idea, and now I get:
(top-gdb) p g_target_stack
$2 = {
m_top = dummy_stratum,
m_stack = {0x1f1b040 <the_dummy_target>, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}
}
I did not do the same for the debug target. It didn't seem as useful
to me.

A customer noticed some mildly odd MI output, where CLI output was
split into multiple MI strings at unusual boundaries, like this:
~"$1 = (b => true"
~", p => 0x407260"
This is technically correct according to the MI spec, but still
unusual, in that there's no particular reason for the string to be
split where it is.
I tracked this down to a call to gdb_flush in generic_val_print.
Then, I went through all calls to gdb_flush and removed the ones I
thought were superfluous. In particular:
* Any call in the value-printing code;
* Likewise the type-printing code (just a single call); and
* Any call that immediately followed a printf that obviously
ended with a newline, my belief being that gdb's standard output
streams are line buffered (by inheriting the behavior from stdio)
Regression tested on x86-64 Fedora 29.
I didn't add a new test case. I tend to think we don't necessarily
want to specify this behavior in the tests. Let me know what you
think of this.

Valgrind reports leaks like the below in various tests,
e.g. gdb.threads/attach-slow-waitpid.exp, gdb.ada/task_switch_in_core.exp, ...
Fix the leak by clearing the regcache when detaching from an inferior.
Note that these leaks are 'created' when GDB exits,
when the regcache::current_regcache is destroyed : the elements
of the forward_list are pointers, and the 'pointed to' memory is not
deleted by the forward_list destructor.
Nevertheless, fixing this leak is good as it makes a bunch of
tests 'leak clean'.
Also, it seems strange to keep a register cache for a process from
which GDB detached : it is not clear if this cache is still valid
after detach. And effectively, when clearing only the regcache,
(and not the frame cache), then the frame cache was still 'pointing'
at this regcache and was used when switching to the child process
in the test gdb.threads/watchpoint-fork.exp, which seems strange.
So, we solve the leak and avoid possible accesses to the regcache
and frame cache of the detached inferior, by clearing both the
regcache and the frame cache.
Tested on debian/amd64, natively, under Valgrind,
and with make check RUNTESTFLAGS="--target_board=native-gdbserver".

This adds a push_target overload that takes a "target_ops_up &&".
This removes some calls to release a target_ops_up, and makes the
intent here clearer.

* target.h (push_target): Declare new overload.
* target.c (push_target): New overload, taking an rvalue reference.
* remote.c (remote_target::open_1): Use push_target overload.
* corelow.c (core_target_open): Use push_target overload.

I noticed that target_stack::unpush first uses the target "t", then
later asserts that it is non-NULL:
strata stratum = t->stratum ();
[...]
gdb_assert (t != NULL);
This is backwards, though, as the assertion must come first.

This replaces the pointer and length parameters of target_pass_signals
and target_program_signals with a gdb::array_view parameter, and fixes
the fallout.
In infrun.c, the signal_stop, signal_print, signal_program,
signal_catch, signal_pass globals are currently pointers to
heap-allocated memory. I see no point in that, so I converted them to
arrays. This allows simplifying the calls to
target_pass_signals/target_program_signals, since we can pass the
array directly, which can implicitly convert to gdb::array_view.

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.

I get this when compiling with a gcc 6.3.0-based cross-compiler:
CXX target.o
/home/simark/src/binutils-gdb/gdb/target.c: In static member function 'static void target_terminal::restore_inferior()':

Accomodate it by dropping the unnecessary struct keyword. Actually, I used
"::inferior", otherwise it resolves to the inferior method of the
target_terminal class.

Running `info os someUnknownOsType` is crashing when gdb is built with
-D_GLIBCXX_DEBUG:
/usr/include/c++/5/debug/vector:439:error: attempt to
access an element in an empty container.
In target_read_stralloc from target.c, the call to
target_read_alloc_1 can return an empty vector, we then call vector::back on
this vector, which is invalid.
This commit adds a check for emptiness before trying to call
vector::back on it. It also adds test to check for `info os <unknown>`
to return the proper error message.
This is a regression in gdb 8.2 and this patch restores the behavior of
previous versions.

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

need for each of the instances to have their own to_stratum copy.

This patch converts the default_child_has_foo functions to
process_stratum_target methods. This simplifies "regular"
non-inf_child process_stratum targets, since they no longer have to
override the target_ops::has_foo methods to call the default_child_foo
functions. A couple targets need to override the new defaults
(corelow and tracefiles), but it still seems like a good tradeoff,
since those are expected to be little different (target doesn't run).

This adds a base class that all process_stratum targets inherit from.

As preparation for multi-target, this patch makes each inferior have
its own thread list.
This isn't absolutely necessary for multi-target, but simplifies
things. It originally stemmed from the desire to eliminate the
init_thread_list calls sprinkled around, plus it makes it more
efficient to iterate over threads of a given inferior (no need to
always iterate over threads of all inferiors).
We still need to iterate over threads of all inferiors in a number of
places, which means we'd need adjust the ALL_THREADS /
ALL_NON_EXITED_THREADS macros. However, naively tweaking those macros
to have an extra for loop, like:
#define ALL_THREADS (thr, inf) \
for (inf = inferior_list; inf; inf = inf->next) \
for (thr = inf->thread_list; thr; thr = thr->next)
causes problems with code that does "break" or "continue" within the
ALL_THREADS loop body. Plus, we need to declare the extra "inf" local
variable in order to pass it as temporary variable to ALL_THREADS
(etc.)
It gets even trickier when we consider extending the macros to filter
out threads matching a ptid_t and a target. The macros become tricker
to read/write. Been there.
An alternative (which was my next attempt), is to replace the
ALL_THREADS etc. iteration style with for_each_all_threads,
for_each_non_exited_threads, etc. functions which would take a
callback as parameter, which would usually be passed a lambda.
However, I did not find that satisfactory at all, because the
resulting code ends up a little less natural / more noisy to read,
write and debug/step-through (due to use of lambdas), and in many
places where we use "continue;" to skip to the next thread now need to
use "return;". (I ran into hard to debug bugs caused by a
continue/return confusion.)
I.e., before:
ALL_NON_EXITED_THREADS (tp)
{
if (tp->not_what_I_want)
continue;
// do something
}
would turn into:
for_each_non_exited_thread ([&] (thread_info *tp)
{
if (tp->not_what_I_want)
return;
// do something
});
Lastly, the solution I settled with was to replace the ALL_THREADS /
ALL_NON_EXITED_THREADS / ALL_INFERIORS macros with (C++20-like) ranges
and iterators, such that you can instead naturaly iterate over
threads/inferiors using range-for, like e.g,.:
// all threads, including THREAD_EXITED threads.
for (thread_info *tp : all_threads ())
{ .... }
// all non-exited threads.
for (thread_info *tp : all_non_exited_threads ())
{ .... }
// all non-exited threads of INF inferior.
for (thread_info *tp : inf->non_exited_threads ())
{ .... }
The all_non_exited_threads() function takes an optional filter ptid_t as
parameter, which is quite convenient when we need to iterate over
threads matching that filter. See e.g., how the
set_executing/set_stop_requested/finish_thread_state etc. functions in
thread.c end up being simplified.
Most of the patch thus is about adding the infrustructure for allowing
the above. Later on when we get to actual multi-target, these
functions/ranges/iterators will gain a "target_ops *" parameter so
that e.g., we can iterate over all threads of a given target that
match a given filter ptid_t.
The only entry points users needs to be aware of are the
all_threads/all_non_exited_threads etc. functions seen above. Thus,
those functions are declared in gdbthread.h/inferior.h. The actual
iterators/ranges are mainly "internals" and thus are put out of view
in the new thread-iter.h/thread-iter.c/inferior-iter.h files. That
keeps the gdbthread.h/inferior.h headers quite a bit more readable.
A common/safe-iterator.h header is added which adds a template that
can be used to build "safe" iterators, which are forward iterators
that can be used to replace the ALL_THREADS_SAFE macro and other
instances of the same idiom in future.
There's a little bit of shuffling of code between
gdbthread.h/thread.c/inferior.h in the patch. That is necessary in
order to avoid circular dependencies between the
gdbthread.h/inferior.h headers.
As for the init_thread_list calls sprinkled around, they're all
eliminated by this patch, and a new, central call is added to
inferior_appeared. Note how also related to that, there's a call to
init_wait_for_inferior in remote.c that is eliminated.
init_wait_for_inferior is currently responsible for discarding skipped
inline frames, which had to be moved elsewhere. Given that nowadays
we always have a thread even for single-threaded processes, the
natural place is to delete a frame's inline frame info when we delete
the thread. I.e., from clear_thread_inferior_resources.

I noticed that if you pass the name of an existing file (not a
directory) as the argument to --data-directory, gdb will crash:
$ ./gdb -nx --data-directory ./gdb
../../binutils-gdb/gdb/target.c:590:56: runtime error: member call on null pointer of type 'struct target_ops'
This was later reported as PR gdb/23838.
This happens because warning ends up calling
target_supports_terminal_ours, which calls current_top_target, which
returns nullptr this early.
This fixes the problem by handling this case specially in
target_supports_terminal_ours. I also changed
target_supports_terminal_ours to return bool.

In my multi-target work, I need to add a few more
scoped_restore_current_thread and switch_to_thread calls in some
places, and in some lower-level places I was fighting against the fact
that switch_to_thread reads/refreshes the stop_pc global.
Instead of piling on workarounds, let's just finally eliminate the
stop_pc global. We already have the per-thread
thread_info->suspend.stop_pc field, so it's mainly a matter of using
that more/instead.
gdb/ChangeLog:
2018-06-28 Pedro Alves <palves@redhat.com>
* gdbthread.h (struct thread_suspend_state) <stop_pc>: Extend
comments.
(switch_to_thread_no_regs): Adjust comment.
* infcmd.c (stop_pc): Delete.
(post_create_inferior, info_program_command): Replace references
to stop_pc with references to thread_info->suspend.stop_pc.
* inferior.h (stop_pc): Delete declaration.
* infrun.c (proceed, handle_syscall_event, fill_in_stop_func)
(handle_inferior_event_1, handle_signal_stop)
(process_event_stop_test, keep_going_stepped_thread)
(handle_step_into_function, handle_step_into_function_backward)
(print_stop_location): Replace references to stop_pc with
references to thread_info->suspend.stop_pc.
(struct infcall_suspend_state) <stop_pc>: Delete field.
(save_infcall_suspend_state, restore_infcall_suspend_state):
Remove references to inf_stat->stop_pc.
* linux-fork.c (fork_load_infrun_state): Likewise.
* record-btrace.c (record_btrace_set_replay): Likewise.
* record-full.c (record_full_goto_entry): Likewise.
* remote.c (print_one_stopped_thread): Likewise.
* target.c (target_resume): Extend comment.
* thread.c (set_executing_thread): New.
(set_executing): Use it.
(switch_to_thread_no_regs, switch_to_no_thread, switch_to_thread):
Remove references to stop_pc.
