gdb/configure --help: suggest --disable-build-with-cxx instead of --enable...

We build by default with a C++ compiler, but "configure --help" still
says "--enable-build-with-cxx", which hints that it is by default
disabled.  Update the --help text.

gdb/ChangeLog:
2016-08-05  Pedro Alves  <palves@redhat.com>

	* build-with-cxx.m4: Change help string to be in terms of
	--disable-build-with-cxx.
	* configure: Regenerate.

Commit: ada8ff522ce970e11dae4a3463c899b64e6f5006

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains

Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).

Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

Fix this by making the functions involved in setjmp/longjmp as
noexcept, so that the compiler knows it doesn't need to emit the
_Unwind_SjLj_Register / _Unwind_SjLj_Unregister calls for C++
exceptions.

Tested on x86_64 Fedora 23 with:
 - GCC 5.3.1 w/ DWARF-based exceptions.
 - GCC 7 built with --enable-sjlj-exceptions.

Add test for user context selection sync

This patch adds a test to verify that events are sent properly to all
UIs when the user selection context (inferior, thread, frame) changes.

The goal of the C test file is to provide two threads that are stopped with the
same predictable backtrace (so that we can test frame switching).  The barrier
helps us know when the child threads are started.  Then, scheduler-locking is
used to bring each thread one by one to the position we expect them to be
during the test.

*** TEST RESULTS FOR COMMIT 1555a1e7846048adeee7b9734ab3ec200d776858 ***

Author: Antoine Tremblay <antoine.tremblay@ericsson.com>
Branch: gdb-7.12-branch
Commit: 1555a1e7846048adeee7b9734ab3ec200d776858

Emit inferior, thread and frame selection events to all UIs

With this patch, when an inferior, thread or frame is explicitly
selected by the user, notifications will appear on all CLI and MI UIs.
When a GDB console is integrated in a front-end, this allows the
front-end to follow a selection made by the user ont he CLI, and it
informs the user about selection changes made behind the scenes by the
front-end.

This patch addresses PR gdb/20487.

In order to communicate frame changes to the front-end, this patch adds
a new field to the =thread-selected event for the selected frame.  The
idea is that since inferior/thread/frame can be seen as a composition,
it makes sense to send them together in the same event.  The vision
would be to eventually send the inferior information as well, if we find
that it's needed, although the "=thread-selected" event would be
ill-named for that job.

Front-ends need to handle this new field if they want to follow the
frame selection changes that originate from the console.  The format of
the frame attribute is the same as what is found in the *stopped events.

Here's a detailed example for each command and the events they generate:

thread
------

1. CLI command:

     thread 1.3

   MI event:

     =thread-selected,id="3",frame={...}

2. MI command:

     -thread-select 3

   CLI event:

     [Switching to thread 1.3 ...]

3. MI command (CLI-in-MI):

     thread 1.3

   MI event/reply:

     &"thread 1.3\n"
     ~"#0  child_sub_function () ...
     =thread-selected,id="3",frame={level="0",...}
     ^done

frame
-----

1. CLI command:

     frame 1

   MI event:

     =thread-selected,id="3",frame={level="1",...}

2. MI command:

     -stack-select-frame 1

   CLI event:

     #1  0x00000000004007f0 in child_function...

3. MI command (CLI-in-MI):

     frame 1

   MI event/reply:

     &"frame 1\n"
     ~"#1  0x00000000004007f9 in ..."
     =thread-selected,id="3",frame={level="1"...}
     ^done

inferior
--------

Inferior selection events only go from the console to MI, since there's
no way to select the inferior in pure MI.

1. CLI command:

     inferior 2

   MI event:

     =thread-selected,id="3"

Note that if the user selects an inferior that is not started or exited,
the MI doesn't receive a notification.  Since there is no threads to
select, the =thread-selected event does not apply...

2. MI command (CLI-in-MI):

     inferior 2

   MI event/reply:

     &"inferior 2\n"
     ~"[Switching to inferior 2 ...]"
     =thread-selected,id="4",frame={level="0"...}
     ^done

Internal implementation detail: this patch makes it possible to suppress
notifications caused by a CLI command, like what is done in mi-interp.c.
This means that it's now possible to use the
add_com_suppress_notification function to register a command with some
event suppressed.  It is used to implement the select-frame command in
this patch.

The function command_notifies_uscc_observer was added to extract
the rather complicated logical expression from the if statement.  It is
also now clearer what that logic does: if the command used by the user
already notifies the user_selected_context_changed observer, there is
not need to notify it again.  It therefore protects again emitting the
event twice.

No regressions, tested on ubuntu 14.04 x86 with target boards unix and
native-extended-gdbserver.

Determine target description for native aarch64

I find the following test fail when I test native aarch64 gdb with
arm program,

(gdb) PASS: gdb.base/attach-pie-noexec.exp: attach
set architecture arm^M
warning: Selected architecture arm is not compatible with reported target architecture aarch64^M
Architecture `arm' not recognized.^M
The target architecture is set automatically (currently aarch64)^M
(gdb) FAIL: gdb.base/attach-pie-noexec.exp: set architecture arm

GDB thinks the target is aarch64, but it isn't.  Nowadays, we are
using some entries AT_PHENT and AT_HWCAP in auxv to determine whether
the process is a 32-bit arm one or 64-bit aarch64 one, and get the
right gdbarch.  However, in the process of parsing auxv (in
inf_ptrace_auxv_parse), the size of int and data pointer of
target_gdbarch is used.  If debug program exists (in most of cases),
target_gdbarch is already set according to the debug program, which
is arm in my case.  Then, GDB can parse auxv successfully.  However,
in gdb.base/attach-pie-noexec.exp, the debug program is removed,
target_gdbarch is aarch64 when GDB parse auxv, so GDB can't parse
it successfully.

Instead of using auxv, we check the return value of ptrace NT_ARM_VFP.
If the program is an arm process, NT_ARM_VFP is OK, otherwise, error
is returned.

Additionally, we only return tdesc_arm_with_neon for arm process,
because neon is mandatory on ARMv8.

PR python/18565 - make Frame.function work for inline frames

PR python/18565 notes that calling frame filters don't work properly for
inlined functions.  This happens because Frame.function on an inline
frame will yield the wrong result.  This patch changes this code to use
find_frame_funname instead, which handles inline frames properly.

Built and regtested on x86-64 Fedora 24.

	PR python/18565:
	* python/py-frame.c (frapy_function): Use find_frame_funname.

2016-08-03  Tom Tromey  <tom@tromey.com>

	PR python/18565:
	* gdb.python/py-frame-inline.exp: Add Frame.function test.

Avoid potential memory leak in find_frame_funname

The PR 18565 thread pointed out that, if cp_remove_params can throw
(we aren't quite sure), then find_frame_funname could leak some
memory.  This patch avoids any potential issue by rearranging some
code in find_frame_funname.

Built and regtested on x86-64 Fedora 24.

2016-08-03  Tom Tromey  <tom@tromey.com>

	* stack.c (find_frame_funname): Avoid any possible leak in case
	cp_remove_params can throw.
