Currently, to open a target, with "target TARGET_NAME", GDB finds the
target_ops instance with "TARGET_NAME" as short name, and then calls
its target_ops::open virtual method. In reality, there's no actual
target/name lookup, a pointer to the target_ops object was associated
with the "target TARGET_NAME" command at add_target time (when GDB is
initialized), as the command's context.
This creates a chicken and egg situation. Consider the case of
wanting to open multiple remote connections. We want to be able to
have one remote target_ops instance per connection, but, if we're not
connected yet, so we don't yet have an instance to call target->open()
on...
This patch fixes this by separating out common info about a target_ops
to a separate structure (shortname, longname, doc), and changing the
add_target routine to take a reference to such an object instead of a
pointer to a target_ops, and a pointer to a factory function that is
responsible to open an instance of the corresponding target when the
user types "target TARGET_NAME".
-extern void add_target (struct target_ops *);
+extern void add_target (const target_info &info, target_open_ftype *func);
I.e. this factory function replaces the target_ops::open virtual
method.
For static/singleton targets, nothing changes, the target_open_ftype
function pushes the global target_ops instance on the target stack.
At target_close time, the connection is tor down, but the global
target_ops object remains live.
However, targets that support being open multiple times will make
their target_open_ftype routine allocate a new target_ops instance on
the heap [e.g., new remote_target()], and push that on the stack. At
target_close time, the new object is destroyed (by the
target_ops::close virtual method).
Both the core target and the remote targets will support being open
multiple times (others could/should too, but those were my stopping
point), but not in this patch yet. We need to get rid of more globals
first before that'd be useful.
Native targets are somewhat special, given find_default_run_target &
friends. Those routines also expect to return a target_ops pointer,
even before we've open the target. However, we'll never need more
than one instance of the native target, so we can assume/require that
native targets are global/simpletons, and have the backends register a
pointer to the native target_ops. Since all native targets inherit
inf_child_target, we can centralize that registration. See
add_inf_child_target, get_native_target/set_native_target and
find_default_run_target.

After the previous target_ops/C++ patches are all squashed and merged,
this one can go in separately.
This patch adjusts all the target methods to return bool instead of int
when they're returning a boolean.

I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

This changes the out parameter of target_read_string to be a
unique_xmalloc_ptr. This avoids a cleanup and sets the stage for more
cleanup removals.
This patch also removes a seemingly needless alloca from
print_subexp_standard.

The recent commit e671cd59 ("Per-inferior target_terminal state, fix
PR gdb/13211, more") missed adjusting a few targets to the new
target_ops->to_interrupt interface, breaking the build for those
targets. This fixes it.
Note: remote-sim doesn't really support async execution, so I don't
think gdbsim_interrupt is ever reached via target_interrupt. (It is
reached via gdbsim_cntrl_c though).
The inflow.c changes are a bit ugly, but they're just doing what other
parts of the file already do to handle the same missing functions.
Targets that don't have 'kill', like mingw have their own
target_ops->to_interrupt implementation, so it's fine to make
child_interrupt be a nop.

The to_detach target_ops method implementations are currently expected
to work on current_inferior/inferior_ptid. In order to make things more
explicit, and remove some "shadow" parameter passing through globals,
this patch adds an "inferior" parameter to to_detach. Implementations
will be expected to use this instead of relying on the global. However,
to keep things simple, this patch only does the minimum that is
necessary to add the parameter. The following patch gives an example of
how one such implementation would be adapted. If the approach is deemed
good, we can then look into adapting more implementations. Until then,
they'll continue to work as they do currently.

I was looking into adding a parameter to target_detach, and was
wondering what the args parameter was. It seems like in the distant
past, it was possible to specify a signal number when detaching. That
signal was injected in the process before it was detached. There is an
example of code handling this in linux_nat_detach. With today's GDB, I
can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work,
because detach is a prefix command and doesn't recognize the sub-command
15. Doing "detach inferiors 15" doesn't work because it expects a list
of inferior id to detach. Therefore, I don't think there's a way of
invoking detach_command with a non-NULL args. I also didn't find any
documentation related to this feature.
I assume that this feature stopped working when detach was made a prefix
command, which is in f73adfeb8bae36885e6ea248d12223ab0d5eb9cb (sorry,
there's no commit title) from 2006. Given that this feature was broken
for such a long time and we haven't heard anything (AFAIK, I did not
find any related bug), I think it's safe to remove it, as well as the
args parameter to target_detach. If someone wants to re-introduce it, I
would suggest rethinking the user interface, and in particular would
suggest using signal name instead of numbers.
I tried to fix all the impacted code, but I might have forgotten some
spots. It shouldn't be hard to fix if that's the case. I also couldn't
build-test everything I changed, especially the nto and solaris stuff.

This removes cmd_cfunc_ftype and the non-const overload of add_cmd;
then fixes up the fallout.
For the most part this patch is straightforward. There are a few
files (go32-nat.c, windows-nat.c, and gnu-nat.c) that I could not
compile; so I made a best effort there.

This changes add_com to take a cmd_const_cfunc_ftype, and then fixes
up all the command implementations.
In most cases this is trivial.
In a couple of places I had to again introduce a temporary non-const
overload. These overloads will be removed when add_info is
constified.

This patches removes get_regcache_arch, and use regache->arch () instead.
The motivation of this change is that I am going to move some basic stuff
into a base class of regcache. I don't need to update "client" code
regcache->arch (). On the other hand, this patch shortens the code a
little bit.

If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)

This commit adds new "set/show cwd" commands, which are used to
set/show the current working directory of the inferior that will be
started.
The idea here is that "set cwd" will become the de facto way of
setting the inferior's cwd. Currently, the user can use "cd" for
that, but there are side effects: with "cd", GDB also switches to
another directory, and that can impact the loading of scripts and
other files. With "set cwd", we separate the logic into a new
command.
To maintain backward compatibility, if the user issues a "cd" command
but doesn't use "set cwd", then the inferior's cwd will still be
changed according to what the user specified. However, "set cwd" has
precedence over "cd", so it can always be used to override it.
"set cwd" works in the following way:
- If the user sets the inferior's cwd by using "set cwd", then this
directory is saved into current_inferior ()->cwd and is used when
the inferior is started (see below).
- If the user doesn't set the inferior's cwd by using "set cwd", but
rather use the "cd" command as before, then this directory is
inherited by the inferior because GDB will have chdir'd into it.
On Unix-like hosts, the way the directory is changed before the
inferior execution is by expanding the user set directory before the
fork, and then "chdir" after the call to fork/vfork on
"fork_inferior", but before the actual execution. On Windows, the
inferior cwd set by the user is passed directly to the CreateProcess
call, which takes care of the actual chdir for us.
This way, we'll make sure that GDB's cwd is not affected by the user
set cwd.

This removes make_cleanup_restore_target_terminal and generally
C++-ifies target terminal handling. It changes all target_terminal_*
functions to be static members of a new target_terminal class and
changes the cleanup to be a scoped_* class.
make_cleanup_override_quit_handler is also removed in favor of simply
using scoped_restore.
Note that there are some files in this patch that I could not compile.
Considering that some of the rewrites were automated, and that none of
these files involed cleanups, I feel that this is relatively safe.
Regression tested by the buildbot.

This patch makes lm_info_windows a "real" class. It initializes the field
and replaces XCNEW/xfree with new/delete.
gdb/ChangeLog:
* windows-nat.c (struct lm_info_windows): Initialize field.
(windows_make_so): Allocate lm_info_windows with new.
(windows_free_so): Free lm_info_windows with delete.

The lm_info structure is used to store target specific information about
mapped libraries. It is currently defined as an opaque type in solist.h
and a pointer to it is included in solist, the target-agnostic object
representing a loaded shared library. Multiple targets define their own
implementation of lm_info.
In anticipation of using C++ stuff (e.g. vector) in the lm_info objects,
we first need to avoid different definitions of classes with the same
name (which violates the one definition rule). This patch does it by
having a base class (lm_info_base) from which all the specific lm_info
derive. Each implementation is renamed to something that makes sense
(e.g. lm_info_aix for AIX). The next logical step would probably be to
derive directly from so_list, it's not really obvious, so I'll keep that
for another day.
One special case is the Neutrino (nto) support. It uses SVR4-style
libraries, but overrides some methods. To do that, it needed to have
its own copy of SVR4's lm_info structure in nto-tdep.c, because it was
just not possible to put it in solib-svr4.h and include that file. Over
time, that copy got out of sync, which is still the case today. I can
only assume that the lm_addr function in nto-tdep.c is broken right now.
The first field of the old lm_info was a pointer (gdb_byte *), whereas
in the new lm_info it's an address in the inferior (CORE_ADDR). Trying
to use that field today probably results in a crash. With this
refactor, it's now possible to put lm_info_svr4 in solib-svr4.h and just
include it. I have adapted the code in nto-tdep.c to that it builds,
but it's probably not correct. Since I don't have the knowledge nor
setup to try this on Neutrino, somebody else would have to fix it. But
I am confident that I am not making things worse than they already are.

'const char *'.
|

As a preparation for the next patch, which will move fork_inferior
from GDB to common/ (and therefore share it with gdbserver), it is
interesting to convert a few functions to C++.
This patch touches functions related to parsing command-line arguments
to the inferior (see gdb/fork-child.c:breakup_args), the way the
arguments are stored on fork_inferior (using std::vector instead of
char **), and the code responsible for dealing with argv also on
gdbserver.
I've taken this opportunity and decided to constify a few arguments to
fork_inferior/create_inferior as well, in order to make the code
cleaner. And now, on gdbserver, we're using xstrdup everywhere and
aren't checking for memory allocation failures anymore, as requested
by Pedro:

IMO this refactoring was very good to increase the readability of the
code as well, because some parts of the argument handling were
unnecessarily confusing before.

When trying to build for x86_64-w64-mingw32:
/home/simark/src/binutils-gdb/gdb/windows-nat.c: In function ‘void windows_detach(target_ops*, const char*, int)’:
/home/simark/src/binutils-gdb/gdb/windows-nat.c:1915:20: error: converting to ‘ptid_t’ from initializer list would use explicit constructor ‘constexpr ptid_t::ptid_t(int, long int, long int)’
ptid_t ptid = {-1};
^
Fixed by initializing ptid with the minus_one_ptid variable.
gdb/ChangeLog:
* windows-nat.c (windows_detach): Initialize ptid with
minus_one_ptid.

This is the remainder boring constification that all looks more of less
borderline obvious IMO.

Use the ptid from the regcache so we don't depend on the current value
of the inferior_ptid global.
Also, change how the current thread is passed to sub-functions. The
windows_fetch_inferior_registers function sets current_thread then calls
do_windows_fetch_inferior_registers, which reads current_thread. This
very much looks like passing a parameter through a global variable. I
think it would be more straightforward to pass the thread as a
parameter.

* windows-nat.c (do_windows_fetch_inferior_registers): Add
windows_thread_info parameter and use it instead of

This introduces a new specialization of gdb::ref_ptr that can be used
to manage BFD reference counts. Then it changes most places in gdb to
use this new class, rather than explicit reference-counting or
cleanups. This patch removes make_cleanup_bfd_unref.
If you look you will see a couple of spots using "release" where a use
of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next
patch.
I think this patch fixes some latent bugs. For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.
I'm not 100% certain that the macho_symfile_read_all_oso change is
correct. The existing code here is hard for me to follow. One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.

* windows-nat.c (windows_delete_thread): Adjusting call to
target_mourn_inferior to include ptid_t argument.
|
|
This patch consolidates the API of target_mourn_inferior between GDB
and gdbserver, in my continuing efforts to make sharing the
fork_inferior function possible between both.
GDB's version of the function did not care about the inferior's ptid
being mourned, but gdbserver's needed to know this information. Since
it actually makes sense to pass the ptid as an argument, instead of
depending on a global value directly (which GDB's version did), I
decided to make the generic API to accept it. I then went on and
extended all calls being made on GDB to include a ptid argument (which
ended up being inferior_ptid most of the times, anyway), and now we
have a more sane interface.
On GDB's side, after talking to Pedro a bit about it, we decided that
just an assertion to make sure that the ptid being passed is equal to
inferior_ptid would be enough for now, on the GDB side. We can remove
the assertion and perform more operations later if we ever pass
anything different than inferior_ptid.
Regression tested on our BuildBot, everything OK.
I'd appreciate a special look at gdb/windows-nat.c's modification
because I wasn't really sure what to do there. It seemed to me that
maybe I should build a ptid out of the process information there, but
then I am almost sure the assertion on GDB's side would trigger.

This is done by catching an exception number 0x406d1388 (it has no
documented name, though MSDN dubs it "MS_VC_EXCEPTION" in one code
example), which is thrown by the program. The exception record
contains an ID of a thread and a name to give it.
This requires rolling back some changes in handle_exception(), which
now again returns more than two distinct values. The new
HANDLE_EXCEPTION_IGNORED value means that gdb should just continue,
without returning the thread ID up the stack (which would result in
further handling of the exception, which is not what we want).

The following change...
commit 43499ea30db2a866412c86952c7e1d7b158d806f
Date: Tue Nov 17 15:17:44 2015 +0000
Subject: [C++/mingw] windows-nat.c casts
... causes a small regression in GDB, where we get the following
warning at startup:
% gdb
C:\[...]\gdb.exe: warning: cannot automatically find executable file or library to read symbols.
Use "file" or "dll" command to load executable/libraries directly.
GNU gdb (GDB) 7.10.50.20151218-cvs (with AdaCore local changes)
[...]
(gdb)
The warning comes from _initialize_loadable which tries to dynamically
load some symbols from kernel32.dll and psapi.dll, and in particular:
hm = LoadLibrary ("psapi.dll");
if (hm)
{
GPA (hm, EnumProcessModules);
GPA (hm, GetModuleInformation);
GPA (hm, GetModuleFileNameEx);
}
The problem is that the new GPA macro assumes that the name of
the variable we use to point to the function, and the name of
its associated symbol are the same. This is mostly the case,
except for GetModuleFileNameEx, where the name is provided by
the GetModuleFileNameEx_name macro (defined differently depending
on whether we are on cygwin or not). As a result, the dynamic
resolution for GetModuleFileNameEx returns NULL, and we trip
the following check which leads to the warning:
if (!EnumProcessModules || !GetModuleInformation || !GetModuleFileNameEx)
{
[...]
warning(_("[...]"));
}
This patch fixes the problem by calling GetProcAddress directly,
rather than through the GPA macro, but in a way which hopefully
avoids the C++ compilation warning that the previous patch was
trying to get rid of.
gdb/ChangeLog:
* windows-nat.c (_initialize_loadable): Fix computing of
GetModuleFileNameEx.

Building in C++ errors out with:

^
Looking at the code, I can't figure out why we treat first chance
exceptions any different here.
AFAICS, we set last_sig to 1, and then call windows_resume passing
signal==1, so the DBG_EXCEPTION_NOT_HANDLED code path in win32_resume
is taken:
~~~
if (sig != GDB_SIGNAL_0)
{
if (current_event.dwDebugEventCode != EXCEPTION_DEBUG_EVENT)
{
OUTMSG (("Cannot continue with signal %d here.\n", sig));
}
else if (sig == last_sig)
continue_status = DBG_EXCEPTION_NOT_HANDLED;
else
OUTMSG (("Can only continue with recieved signal %d.\n", last_sig));
}
~~~
Fix this by removing this special casing. gdbserver also goes
straight to continuing with DBG_EXCEPTION_NOT_HANDLED, AFAICS.

Explation below based on what Joel wrote at:
https://sourceware.org/ml/gdb-patches/2015-10/msg00274.html
The merge async/sync code paths patch broke attaching on Windows.
This is what we observe, after attaching to any process. At first, it
seems like everything worked fine, since the process stops, and we get
the prompt back:
(gdb) att 3156
Attaching to program `C:\[...]\foo.exe', process 3156
[New Thread 3156.0xcd8]
[New Thread 3156.0xfe4]
0x7770000d in ntdll!DbgBreakPoint () from C:\Windows\SysWOW64\ntdll.dll
(gdb)
However, enter any commands at all, and GDB appears to be hanging.
For instance:
(gdb) set lang ada
[nothing happens]
Despite appearances, GDB is not reading from the prompt. It is
blocked waiting for an event from the inferior. And since our
inferior is stopped, there aren't going to be any events to read.
In chronological order, what happens is that windows_attach calls
do_initial_windows_stuff, which performs the inferior creation,
and repeatedly waits until we get the first SIGTRAP:
while (1)
{
stop_after_trap = 1;
wait_for_inferior ();
tp = inferior_thread ();
if (tp->suspend.stop_signal != GDB_SIGNAL_TRAP)
resume (tp->suspend.stop_signal);
else
break;
}
The call to wait_for_inferior triggers a call to do_target_wait to get
the event, followed by handle_inferior_event to process it. However,
because the first couple of events are "spurious" events, GDB resumes
the execution, and prepares the inferior to wait again:
case TARGET_WAITKIND_SPURIOUS:
[...]
resume (GDB_SIGNAL_0);
prepare_to_wait (ecs);
And prepare_to_wait just does...
ecs->wait_some_more = 1;
if (!target_is_async_p ())
mark_infrun_async_event_handler ();
... which as a result sets the infrun_async_event_handler "ready"
flag to 1.
We get a couple of spurious events before we get the initial SIGTRAP,
at which point we exit the "while (1)" loop above, after which we
reach the end of the attach_command, followed by the normal
end-of-command processing (normal_stop, bp handling, printing the GDB
prompt), back finally to the root of the event loop.
Notice that, at this point, nothing has unset the "ready" flag for the
infrun_async_event_handler. So, when another cycle of
gdb_do_one_event from the event loop, we eventually call
check_async_event_handlers, which finds that the infrun async event
handler is "ready", and therefore calls it's associated "proc"
callback, which does...
inferior_event_handler (INF_REG_EVENT, NULL);
... triggering a blocking call to target_wait, thus hanging forever.
The fix is to use windows_wait and windows_resume directly, similarly
to gdbserver. This will also allow getting rid of 'stop_after_trap'.
gdb/ChangeLog:
2015-10-22 Pedro Alves <palves@redhat.com>
* windows-nat.c (do_initial_windows_stuff): Rewrite loop using
windows_wait and windows_resume directly instead of
wait_for_inferior and resume.

This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

+FAIL: gdb.base/interrupt-noterm.exp: inferior received SIGINT (timeout)
+testcase src/gdb/testsuite/gdb.base/interrupt-noterm.exp completed in 10 seconds
That is, we get "[$thread] #1 stopped" instead of SIGINT.
The issue is that we don't currently distinguish send
"interrupt/ctrl-c" to target terminal vs "stop/pause" thread well;
both cases go through "target_stop".
And then, the native Linux backend (linux-nat.c) implements
target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop
mode. Since "maint set target-non-stop on" forces the backend to be
always running in non-stop mode, even though the user-visible behavior
is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of
the SIGINT the test expects.
Fix this by introducing a target_interrupt method to use in the
"interrupt/ctrl-c" case, so "set non-stop off" can always work the
same irrespective of "maint set target-non-stop on/off". I'm
explictly considering changing the "set non-stop on" behavior as out
of scope here.
Most of the patch is an across-the-board rename of to_stop hook
implementations to to_interrupt. The only targets where something
more than a rename is being done are linux-nat.c and remote.c, which
are the only targets that support async, and thus are the only ones
the core side calls target_stop on.

Replace __COPY_CONTEXT_SIZE conditional with __CYGWIN__
__COPY_CONTEXT_SIZE was added to Cygwin's headers in 2006.
Versions of Cygwin which don't define __COPY_CONTEXT_SIZE are long obsolete.
Also see the thread starting at
https://sourceware.org/ml/gdb-patches/2015-03/msg00989.html for some discussion
Note that __COPY_CONTEXT_SIZE should just be sizeof(CONTEXT) (which is a
platform constant), but isn't due to historical mistakes in Cygwin headers.
gdb/ChangeLog:
2015-06-03 Jon Turney <jon.turney@dronecode.org.uk>
* windows-nat.c (do_windows_fetch_inferior_registers)
(handle_output_debug_string): Replace __COPY_CONTEXT_SIZE
conditional with __CYGWIN__.

Discussed somewhat in the thread at
https://cygwin.com/ml/gdb-patches/2013-06/msg00680.html
This is pretty straightforward to demonstrate on Cygwin currently:
$ cat main.c
int main()
{
return 0;
}
$ gcc -g -O0 main.c -o main
$ ./gdb ./main
[...]

For cosmetic purposes, trim a trailing '\n' from OutputDebugString before
echoing it, as warning() will add a '\n', anyhow.

The "info dll", an alias of the "info sharedlibrary" command, is
currently only defined in windows native versions. This patch makes
it universally available by moving the alias declaration to solib.c,
and adjusts the documentation accordingly.
Making it universally available has two benefits:
- Windows users moving to a Unix platforms are still able to use
the same command for getting the list of shared libraries;
- Unix to Windows cross debuggers now provide that command also.
gdb/ChangeLog:
* solib.c (_initialize_solib): Add "info dll" alias creation.
* windows-nat.c (set_windows_aliases): Delete.
(_initialize_windows_nat): Remove deprecated_init_ui_hook
assignment.
* NEWS: Add news entry about "info dll" now being available
on all platforms.
gdb/doc/ChangeLog:
* gdb.texinfo (Files): Add "info dll" documentation.
(Cygwin Native): Remove "info dll" documentation.
