7fdc15218d remove pop_target
This patch fixes the target double-close problem (PR remote/15266),
and in the process removes pop_target entire (PR remote/15256).

The first issue is that pop_target calls target_close.  However, it
then calls unpush_target, which also calls target_close.  This means
targets must be able to be closed twice.  Not only is this strange,
but it also directly contradicts the contract of to_xclose targets.
(We currently have just a single such target, and it is never pushed;
but I plan to add more, and so this latent bug is triggered.)

The second issue is that it seems to me that calling pop_target is
often unsafe.  This is what cropped up in 15256, where the remote
target assumed that it could pop_target -- but there was another
target higher on the stack, leading to confusion.

But, it is always just as easy to call unpush_target as it is to call
pop_target; and it is also safer.  So, removing pop_target seemed like
an improvement.

Finally, this adds an assertion to target_close to ensure that no
currently-pushed target can be closed.

Built and regtested on x86-64 Fedora 18; both natively and using the
native-gdbserver board file.

	PR remote/15256, PR remote/15266:
	* bfd-target.c (target_bfd_reopen): Initialize to_magic.
	* monitor.c (monitor_detach): Use unpush_target.
	* remote-m32r-sdi.c (m32r_detach): Use unpush_target.
	* remote-mips.c (mips_detach): Use unpush_target.  Don't
	call mips_close.
	* remote-sim.c (gdbsim_detach): Use unpush_target.
	* target.c (pop_target): Remove.
	(pop_all_targets_above): Don't call target_close.
	(target_close): Assert that the target is unpushed.
	* target.h (pop_target): Don't declare.
	* tracepoint.c (tfile_open): Use unpush_target.

c22a2b88fe don't call add_target for thread_db_ops
Right now, "help target" will include this line:

    target multi-thread -- Threads and pthreads support

However, it doesn't make sense to invoke "target multi-thread".

This patch fixes the problem by not registering the multi-thread
target.  add_target does some needed initialization of the target_ops,
so I broke this out into a new function.

It isn't clear to me whether this patch requires a test case or not.
I'm not sure whether there are other unregistered targets; but if
there are, it seems unlikely that we test for their absence from the
help.

Built and regtested on x86-64 Fedora 18.

	* linux-thread-db.c (init_thread_db_ops): Call
	complete_target_initialization.
	(_initialize_thread_db): Don't call add_target.
	* target.c (complete_target_initialization): New function.
	(add_target_with_completer): Call it.
	* target.h (complete_target_initialization): Declare.

5d0a3b53c0 gdb/testsuite/gdb.base: Enable disp-step-syscall.exp tests for ARM.
disp-step-syscall.exp is not run for ARM targets because ARM syscall
instructions have not been added to the list of possible syscall
instructions. This patch adds ARM syscall instructions to enable
disp-step-syscall.exp tests for ARM targets. Attached patch is tested
on ARMv7 and helps pass all disp-step-syscall.exp tests for ARM
targets.

2013-07-19  Omair Javaid  <Omair.Javaid@linaro.org>

	* gdb.base/disp-step-syscall.exp: Add svc and swi syscall
	instructions and enable disp-step-syscall for arm targets.
