7c5ded6a00 C++-fy and prepare for sharing fork_inferior
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.

bc1e6c81d5 Consolidate target_mourn_inferior between GDB and gdbserver
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.

0f48b75707 Factor out "Detaching from program" message printing
Several targets have a copy of the same code that prints

 "Detaching from program ..."

in their target_detach implementation.  Factor that out to a common
function.

(For now, I left the couple targets that print this a bit differently
alone.  Maybe this could be further pulled out into infcmd.c.  If we
did that, and those targets want to continue printing differently,
this new function could be converted to a target method.)

651ce16aa7 Do target_terminal_ours in query & friends instead of in all callers
Any time a caller calls query & friends / prompt_for_continue without
ensuring that gdb owns the terminal for input is a bug.  So do that in
defaulted_query / prompt_for_continue directly instead.

An example of a case where we currently miss calling
target_terminal_ours is internal_error.  Ever since defaulted_query
was made to use gdb_readline_callback, there's no way to answer the
internal error query if the internal error happens while the target is
has the terminal:

 src/gdb/extension.c:698:41: error: invalid conversion from ‘void (*)()’ to ‘__sighandler_t {aka void (*)(int)}’ [-fpermissive]
    signal (SIGINT, handler_state->handler);
					  ^
 In file included from build-gnulib/import/signal.h:52:0,
		  from ../../src/gdb/extension.c:24:
 /usr/include/signal.h:102:23: error:   initializing argument 2 of ‘void (* signal(int, __sighandler_t))(int)’ [-fpermissive]
  extern __sighandler_t signal (int __sig, __sighandler_t __handler)
			^

Instead of this everywhere:

 -  RETSIGTYPE (*handle_sigint_for_compare) () = handle_sigint;
 +  RETSIGTYPE (*handle_sigint_for_compare) (int) = handle_sigint;

Use sighandler_t (a GNU extension).  That's OK to use unconditionaly
because gnulib's signal.h replacement makes sure that it is available.

8d7493201c Replace some xmalloc-family functions with XNEW-family ones
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.

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.

f486487f55 Mostly trivial enum fixes
This is a patch I extracted from Pedro's C++ branch.  It contains the
most trivial enum fixes, where an integer type/value was used instead
of the appropriate enum type/value.  It fixes many C++ errors, since
in C++ you can't mix integers and enums implicitely.

Regardless of the C++ conversion, I think this is a good cleanup to make
use of the appropriate enum types.

Regression-tested on native x86_64.

fe978cb071 C++ keyword cleanliness, mostly auto-generated
This patch renames symbols that happen to have names which are
reserved keywords in C++.

Most of this was generated with Tromey's cxx-conversion.el script.
Some places where later hand massaged a bit, to fix formatting, etc.
And this was rebased several times meanwhile, along with re-running
the script, so re-running the script from scratch probably does not
result in the exact same output.  I don't think that matters anyway.

e8032dde10 Push pruning old threads down to the target
When GDB wants to sync the thread list with the target's (e.g., due to
"info threads"), it calls update_thread_list:

 update_thread_list (void)
 {
   prune_threads ();
   target_find_new_threads ();
   update_threads_executing ();
 }

And then prune_threads does:

 prune_threads (void)
 {
   struct thread_info *tp, *next;

   for (tp = thread_list; tp; tp = next)
     {
       next = tp->next;
       if (!thread_alive (tp))
	 delete_thread (tp->ptid);
     }
 }

Calling thread_live on each thread one by one is expensive.

E.g., on Linux, it ends up doing kill(SIG0) once for each thread.  Not
a big deal, but still a bunch of syscalls...

With the remote target, it's cumbersome.  That thread_alive call ends
up generating one T packet per thread:

 Sending packet: $Tp2141.2150#82...Packet received: OK
 Sending packet: $Tp2141.214f#b7...Packet received: OK
 Sending packet: $Tp2141.2141#82...Packet received: OK
 Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n

That seems a bit silly when target_find_new_threads method
implementations will always fetch the whole current set of target
threads, and then add those that are not in GDB's thread list, to
GDB's thread list.

This patch thus pushes down the responsibility of pruning dead threads
to the target_find_new_threads method instead, so a target may
implement pruning dead threads however it wants.

Once we do that, target_find_new_threads becomes a misnomer, so the
patch renames it to target_update_thread_list.

The patch doesn't attempt to do any optimization to any target yet.
It simply exports prune_threads, and makes all implementations of
target_update_thread_list call that.  It's meant to be a no-op.

0d5ed15352 Avoid software breakpoint's instruction shadow inconsistency
This change:

commit b775012e84
Author: Luis Machado <luisgpm@br.ibm.com>
Date:   Fri Feb 24 15:10:59 2012 +0000

    2012-02-24  Luis Machado  <lgustavo@codesourcery.com>

	* remote.c (remote_supports_cond_breakpoints): New forward
	declaration.
[...]

changed the way breakpoints are inserted and removed such that
`insert_bp_location' can now be called with the breakpoint being handled
already in place, while previously the call was only ever made for
breakpoints that have not been put in place.  This in turn caused an
issue for software breakpoints and targets for which a breakpoint's
`placed_address' may not be the same as the original requested address.

The issue is `insert_bp_location' overwrites the previously adjusted
value in `placed_address' with the original address, that is only
replaced back with the correct adjusted address later on when
`gdbarch_breakpoint_from_pc' is called.  Meanwhile there's a window
where the value in `placed_address' does not correspond to data stored
in `shadow_contents', leading to incorrect instruction bytes being
supplied when `one_breakpoint_xfer_memory' is called to supply the
instruction overlaid by the breakpoint.

And this is exactly what happens on the MIPS target with software
breakpoints placed in microMIPS code.  In this case not only
`placed_address' is not the original address because of the ISA bit, but
`mips_breakpoint_from_pc' has to read the original instruction to
determine which one of the two software breakpoint instruction encodings
to choose as well.  The 16-bit encoding is used to replace 16-bit
instructions and similarly the 32-bit one is used with 32-bit
instructions, to satisfy branch delay slot size requirements.

The mismatch between `placed_address' and the address data in
`shadow_contents' has been obtained from leads to the wrong encoding
being used in some cases, which in the case of a 32-bit software
breakpoint instruction replacing a 16-bit instruction causes corruption
to the adjacent following instruction and leads the debug session astray
if execution reaches there e.g. with a jump.

To address this problem I made the change below, that adds a
`reqstd_address' field to `struct bp_target_info' and leaves
`placed_address' unchanged once it has been set.  This ensures data in
`shadow_contents' is always consistent with `placed_address'.

This approach also has this good side effect that all the places that
examine the breakpoint's address see a consistent value, either
`reqstd_address' or `placed_address', as required.  Currently some
places see either the original or the adjusted address in
`placed_address', depending on whether they have been called before
`gdbarch_remote_breakpoint_from_pc' or afterwards.  This is in
particular true for subsequent calls to
`gdbarch_remote_breakpoint_from_pc' itself, e.g. from
`one_breakpoint_xfer_memory'.  This is also important for places like

014f9477f4 constify to_open
This makes target_ops::to_open take a const string and then fixes the
fallout.

There were a few of these I could not build.  However I eyeballed it
and in any case the fixes should generally be trivial.

This is based on the patch to fix up the target debugging for to_open,
because that changes gdb to not directly install to_open as the target
command

c0939df1ce constify to_attach
This constifies the "args" argument to the target_ops to_attach
method.

I updated all instances of the method.  I could not compile all of
them but I hand-inspected them.  In all cases either the argument is
ignored, or it is passed to parse_pid_to_attach.  (linux-nat does some
extra stuff, but that one I built...)

If you want to try it on your host of choice, please do so.

The code in parse_pid_to_attach seems a little bogus to me.  If there
is a platform with a broken strtoul, we have better methods for fixing
the issue now.  However, I left the code as is since it is clearly ok
to do so.

Built and regtested on x86-64 Fedora 20.

c1ee2fb3cb Native targets: Add inf-child.c:inf_child_mourn_inferior and use it.
Most ports do the same thing in the tail of their mourn routine - call
generic_mourn_inferior+inf_child_maybe_unpush_target.

This factors that out to a convenience function.  More could be done,
but this converts only the really obvious ones.

Tested by building GDB on x86_64 Fedora 20, mingw32 and djgpp.  The
rest is untested, but I think a patch can't get more obvious.

6a3cb8e88a Allow making GDB not automatically connect to the native target.
Sometimes it's useful to be able to disable the automatic connection
to the native target.  E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run".  That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended.  Same thing with "attach",
"info os", etc.

With the patch, we now can have this instead:

 (gdb) set auto-connect-native-target off
 (gdb) target extended-remote :9999
 ...
 *gdb disconnects*
 (gdb) run
 Don't know how to run.  Try "help target".

To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.

Before:

 (gdb) target native
 Use the "run" command to start a native process.

After:

 (gdb) target native
 Done.  Use the "run" command to start a process.
 (gdb) maint print target-stack
 The current target stack is:
   - native (Native process)
   - exec (Local exec file)
   - None (None)
 (gdb) run
 Starting program: ./a.out
 ...

I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode).  With a non-native-target board, it's always a
bug to launch a program with the native target.  Turns out we still
have one such case this patch catches:

 (gdb) break main
 Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
 (gdb) run
 Don't know how to run.  Try "help target".
 (gdb) FAIL: gdb.base/corefile.exp: run: with core

On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before.  This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged.  The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:

 have_inferiors (void)
 {
   for (inf = inferior_list; inf; inf = inf->next)
     if (inf->pid != 0)
       return 1;

It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check.  To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.

Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.

Confirmed a cross build of djgpp gdb still builds.

Smoke tested a cross build of Windows gdb under Wine.

Untested otherwise.

I happened to notice that nto-procfs.c defines

however.

6a109b6b2c add "this" pointers to more target APIs
A subsequent pass introduces delegation helper functions to the target
API.  This delegation is much cleaner if the target_ops pointer is
directly available at delegation time.

This patch adds the "this" pointer to various to_* methods for this
purpose.

This updates a number of ports which I am unable to test.  Please give
them a look-over.  Any possible problem here is trivial, though, as
all that is required is adding an argument to a function.

This removes gdb_dirent.h and updates the code to use dirent.h
instead.  It also removes the now-useless configure checks.

0e9f083f4c remove gdb_string.h
This removes gdb_string.h.  This patch is purely mechanical.  I
created it by running the two commands:

    git rm common/gdb_string.h
    perl -pi -e's/"gdb_string.h"/<string.h>/;'  *.[chyl] */*.[chyl]

52554a0e32 constify to_detach
This patch constifies the target_ops method to_detach.

This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.

In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors.  kill_or_detach calls target_detach, passing
the same argument each time.  So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.

I could not build every target I modified in this patch.  I've
inspected them all by hand, though.  Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath.  The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

28e7fd6234 Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
