e75fdfcad1 clean up some target delegation cases 
This patch cleans up some minor inconsistencies in target delegation.
It's primary purpose is to avoid confusion in the code.  A few spots
were checking the "beneath" target; however this can only be NULL for
the dummy target, so such tests are not needed.  Some other spots were
iterating over the beneath targets, looking for a method
implementation.  This is not needed for methods handled by
make-target-delegates, as there is always an implementation.

1d1f1ccb33 make_corefile_notes: have caller free returned memory 
The various make_corefile_notes implementations for gdbarch as well as target
currently make an xfree cleanup on the data they return.  This causes problems
when trying to put a TRY_CATCH around the make_corefile_notes call.
Specifically, we get a stale cleanup error in restore_my_cleanups.

Omit the make_cleanup and have the caller free the memory.

7bc112c1b9 constify to_info_proc and friends 
This makes a parameter of to_info_proc const and then fixes up some
fallout, including parameters in a couple of gdbarch methods.

I could not test the procfs.c change.  I verified it by inspection.
If this causes an error here, it will be trivial to fix.

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.

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.

a69900ae4e Rename Solaris's target to "target child" like most other ports. 
Note that "target procfs" is used by QNX, but the test must be failing
there, as nto-procfs.c overrides to_open with a method that doesn't
throw the error being tested.  So I'm just removing the test
completely.

e96027e0d9 procfs.c: Don't install a deprecated_xfer_memory method 
This removes yet another instance of a deprecated_xfer_memory user,
and fixes a nasty regression as a side-effect:

    (gdb) start
    Temporary breakpoint 1 at 0x19070: file simple_main.adb, line 4.
    Starting program: /[...]/simple_main
    Warning:
    Cannot insert breakpoint 1.
    Cannot access memory at address 0x19070
    Cannot insert breakpoint -3.
    Temporarily disabling shared library breakpoints:
    breakpoint #-3

The regression was introduced by the to_xfer_partial transition
to return a status enum.  procfs_xfer_partial was updated but
not the case where object is TARGET_OBJECT_MEMORY.  As result,
procfs_xfer_partial was returning the length xfered rather than
the status, and the xfered buffer was left uninitialized.

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.

9b409511d0 Return target_xfer_status in to_xfer_partial 
This patch does the conversion of to_xfer_partial from

    LONGEST (*to_xfer_partial) (struct target_ops *ops,
				enum target_object object, const char *annex,
				gdb_byte *readbuf, const gdb_byte *writebuf,
				ULONGEST offset, ULONGEST len);

to

    enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops,
				enum target_object object, const char *annex,
				gdb_byte *readbuf, const gdb_byte *writebuf,
				ULONGEST offset, ULONGEST len, ULONGEST *xfered_len);

It changes to_xfer_partial return the transfer status and the transfered
length by *XFERED_LEN.  Generally, the return status has three stats,

 - TARGET_XFER_OK,
 - TARGET_XFER_EOF,
 - TARGET_XFER_E_XXXX,

See the comments to them in 'enum target_xfer_status'.  Note that
Pedro suggested not name TARGET_XFER_DONE, as it is confusing,
compared with "TARGET_XFER_OK".  We finally name it TARGET_XFER_EOF.

With this change, GDB core can handle unavailable data in a convenient
way.

The rationale behind this change was mentioned here
https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html

Consider an object/value like this:

  0          100      150        200           512
  DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III

where D is valid data, and xxx is unavailable data, and I is beyond
the end of the object (Invalid).  Currently, if we start the
xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes.
The xfer machinery then retries fetching [100,512), and gets back
TARGET_XFER_E_UNAVAILABLE.  That's sufficient when you're either
interested in either having the whole of the 512 bytes available,
or erroring out.  But, in this scenario, we're interested in
the data at [150,512).  The problem is that the last
TARGET_XFER_E_UNAVAILABLE gives us no indication where to
start the read next.  We'd need something like:

get me [0,512) >>>
     <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK

get me [100,512)  >>> (**1)
     <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE.

get me [150,512) >>>
     <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK.

get me [200,512) >>>
     <<< no more data, return TARGET_XFER_EOF.

This naturally implies pushing down the decision of whether
to return TARGET_XFER_E_UNAVAILABLE or something else
down to the target.  (Which kinds of leads back to tfile
itself reading from RO memory from file (though we could
export a function in exec.c for that that tfile delegates to,
instead of re-adding the old code).

Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to
check whether a status is an error or not, to stop using "status < 0".
This patch also eliminates the comparison between status and 0.

No target implementations to to_xfer_partial adapts this new
interface.  The interface still behaves as before.

Hi,
This patch replaces -1 with TARGET_XFER_E_IO in the implementations of
to_xfer_partial and their callees.  This change is quite mechanical,

25790f6fc1 Remove assert in procfs.c::procfs_make_note_section (x86-solaris) 
On x86-solaris, the gcore command sometimes triggers the following
internal error:

    (gdb) gcore
    /[...]/procfs.c:5523: internal-error: procfs_make_note_section: Assertion `thread_args.note_data != note_data' failed.

The problem is extremely elusive, for reasons that will become clearer
as I explain what is going on.

The program used to produce this issue was really simple:

    | void break_me (void) { }
    |
    | int
    | main (void)
    | {
    |   break_me ();
    |   return 0;
    | }

The procfs_make_note_section builds a buffer incrementally with
the contents of the core's notes section.  The interesting bits are:

  char *note_data = NULL;
  [...]
  note_data = (char *) elfcore_write_prpsinfo (obfd,
                                               note_data,
                                               note_size,
                                               fname,
                                               psargs);

This is the first call to bfd's elfcore which initializes note_data.
After that, we have a few more calls, which keep updating notes_data
and note_size, but our interest lies in the following part of
the function:

  thread_args.note_data = note_data;
  [...]
  proc_iterate_over_threads (pi, procfs_corefile_thread_callback,
                             &thread_args);
  /* There should be always at least one thread.  */
  gdb_assert (thread_args.note_data != note_data);

The comment implies that the assert is to verify that our loop
iterated over at least one thread. The check is relying on the
fact that the notes_data returned by the elfcore module changes
at each iteration, via (in procfs_corefile_thread_callback):

      args->note_data = procfs_do_thread_registers (args->obfd, ptid,
                                                    args->note_data,
                                                    args->note_size,
                                                    args->stop_signal);

(which calls elfcore_write_lwpstatus).

But, while it happens most of the time, thanks to a call to realloc
in elfcore_write_note (the function that actually appends the data
at the end of the notes buffer),...

       buf = (char *) realloc (buf, *bufsiz + newspace);

... this is by no means guarantied. In fact, under the right
circumstances, the buffer was grown twice without changing
addresses. Unfortunately, the circumstances are very sensitive,
thus making this bug very elusive.

This patch fixes the problem by simply removing the assert.
This means we're losing the assertion that there is at least one
thread, but I think that's OK. If we still want to keep the
assertion, we have the option of either checking the buffer
size, or else adding a boolean flag in the context structure
that we'd set to true as soon as we have a thread.

gdb/ChangeLog:

        * procfs.c (procfs_make_note_section): Remove assertion and
        associated comment.

This patch adds a typedef target_xfer_partial_ftype.  When we change

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.

98882a2651 Make STARTUP_WITH_SHELL a runtime toggle -- add new "set/show startup-with-shell" option. 
Occasionaly we hear about people having problems with GDB not being
able to start programs (with "run"/"start").  GDB spawns a shell to
start the program, and most often, it'll be the case that the problem
is actually with the user's shell setup.

GDB has code to disable the use of the shell to start programs.
That's the STARTUP_WITH_SHELL macro that native targets could set to 0
in their nm.h file (though no target actually uses it nowadays).

This patch makes that setting a run-time knob instead.  This will be
useful to quickly diagnose such shell issues, and might also come in
handy at other times (such as when debugging the shell itself, if you
don't have a different shell handy).
