testsuite: Fix false FAIL for gdb.base/morestack.exp

Since
[commit] [testsuite patch] Fix gcc_compiled for gcc 6 & 7
https://sourceware.org/ml/gdb-patches/2016-10/msg00620.html

there has started running again
 Running gdb/testsuite/gdb.base/morestack.exp ...
+FAIL: gdb.base/morestack.exp: continue
+PASS: gdb.base/morestack.exp: up 3000

but as you can see it FAILs now - on Fedora 24 x86_64 (although for example it
still PASSes on CentOS-7.2 x86_64).

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff787c7bb in malloc_consolidate (av=av@entry=0x7ffff7bbcb00 <main_arena>) at malloc.c:4181

[...]

This apparently is due to - man gcc - -fsplit-stack:
When code compiled with -fsplit-stack calls code compiled without
-fsplit-stack, there may not be much stack space available for the
latter code to run.  If compiling all code, including library code,
with -fsplit-stack is not an option, then the linker can fix up these
calls so that the code compiled without -fsplit-stack always has
a large stack.  Support for this is implemented in the gold linker in
GNU binutils release 2.21 and later.

[GDBserver] Fix conversion warning

I got the following warning if I build GDBserver for aarch64_be-linux-gnu,

git/gdb/gdbserver/linux-aarch64-low.c:1539:39: error: invalid conversion from 'void*' to 'uint32_t* {aka unsigned int*}' [-fpermissive]

Make some dwarf_expr_context methods pure virtual

This patch changes some dwarf_expr_context to be pure virtual, as
mentioned during the discussion of an earlier patch in this series.

2016-10-21  Tom Tromey  <tom@tromey.com>

* dwarf2expr.h (class dwarf_expr_context)
<get_frame_base, get_frame_cfa, get_tls_address, dwarf_call,
push_dwarf_block_entry_value, get_addr_index, get_object_address>:
Now pure virtual.
* dwarf2-frame.c (class dwarf_expr_executor)
<get_frame_base, get_frame_cfa, get_tls_address, dwarf_call,
push_dwarf_block_entry_value, get_addr_index, get_object_address>:
New methods.
<invalid>: New method.

Change minimal_symbol_reader::record_full to take a bool

This changes an "int" to a "bool" in the signature for
minimal_symbol_reader::record_full, and then fixes the callers.

2016-10-21  Tom Tromey  <tom@tromey.com>

* minsyms.h (minimal_symbol_reader::record_full): "copy_name" now
a bool.
(record, record_with_info): Update.
* minsyms.c (record): Fix indentation.
(record_full): Fix indentation.  Update for type change.
* elfread.c (record_minimal_symbol): "copy_name" now a bool.
(elf_symtab_read): "copy_names" now a bool.
(elf_rel_plt_read, elf_read_minimal_symbols): Update.

Remove last cleanup from captured_main_1

An earlier patch split captured_main into two parts.  This patch
removes the last remaining cleanup from captured_main_1, and also
replaces a second hand-rolled VEC-like array with a std::vector.

2016-10-21  Tom Tromey  <tom@tromey.com>

* main.c: Include <vector>.
(cmdarg_s): Remove typedef.  Don't define VEC.
(captured_main_1): Use vector, not VEC.  Remove cleanups.

Convert dwarf_expr_context_funcs to methods

This patch converts the function pointers in dwarf_expr_context_funcs
into methods on dwarf_expr_context, and then updates the various
implementations and callers to follow.

NB this patch uses "override" (which caught a couple of renaming bugs
during development) -- but this is C++11, so this patch at least has
to wait for Pedro's patch that adds the OVERRIDE macro.

After this patch it would be possible to do one more, that makes
various members of dwarf_expr_context "protected"; but I haven't done
this.

Convert DWARF expr functions to methods

This converts various DWARF expr functions to be members on
dwarf_expr_context, then fixes up the various users.  This results in
somewhat less wordy code and sets the stage for the next patch.

Initial conversion of dwarf_expr_ctx

This is the first step in the conversion of dwarf_expr_ctx to a C++
class.  This conversion is done in steps to make the patches, and the
reviews, a bit simpler.  This patch changes dwarf_expr_ctx to be
stack-allocated and removes the associated cleanup.

2016-10-21  Tom Tromey  <tom@tromey.com>

* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Stack-allocate
dwarf_expr_context.  Remove cleanups.

into constructor.
(free_dwarf_expr_context, free_dwarf_expr_context_cleanup):
Remove.
(~dwarf_expr_context): Rename from
make_cleanup_free_dwarf_expr_context.  Turn into destructor.

Some cleanup removal in dwarf2loc.c

This removes some cleanups and manual allocation handling in
dwarf2loc.c with std::vector.  Note that this patch has a case where
the vector would normally fall into the "use gdb::unique_ptr"
guidelines -- but here because the vector is immediately initialized,
I moved the initialization into the constructor call, for further
code savings.

2016-10-21  Tom Tromey  <tom@tromey.com>

* dwarf2loc.c: Include <vector>.
(read_pieced_value, write_pieced_value)
(dwarf2_compile_expr_to_ax): Use std::vector.

Remove make_cleanup_restore_current_uiout

This removes make_cleanup_restore_current_uiout in favor of an
RAII-based class.

2016-10-21  Tom Tromey  <tom@tromey.com>

* stack.c (print_stack_frame_to_uiout): Use scoped_restore.
* ui-out.c (make_cleanup_restore_current_uiout)

* infrun.c (print_stop_event): Use scoped_restore.
* ui-out.h (make_cleanup_restore_current_uiout): Don't declare.

Use gdb::unique_ptr in elf_read_minimal_symbols

This changes elf_read_minimal_symbols to use gdb::unique_ptr rather
than an explicit allocation.  This removes a cleanup.

2016-10-21  Tom Tromey  <tom@tromey.com>

* elfread.c (elf_read_minimal_symbols): Use gdb::unique_ptr.

Replace two xmallocs with unique_ptr

This replaces a couple of uses of xmalloc with gdb::unique_ptr, also
removing a couple of cleanups.

2016-10-21  Tom Tromey  <tom@tromey.com>

* cli/cli-dump.c (dump_memory_to_file): Use gdb::unique_ptr.
(restore_binary_file): Likewise.

Change command stats reporting to use class

This removes make_command_stats_cleanup in favor of an RAII class.
The patch is reasonably straightforward, but keeping the same
semantics without excessive reindentation required splitting
captured_main in two.

2016-10-21  Tom Tromey  <tom@tromey.com>

* maint.h (scoped_command_stats): New class.
(make_command_stats_cleanup): Don't declare.

destructor.

Now a constructor.
* main.c (captured_main_1): New function.  Use
scoped_command_stats.
(captured_main): Call captured_main_1.
* event-top.c (command_handler): Use scoped_command_stats.

Remove some cleanups in MI

This patch removes a couple of cleanups from MI by using
gdb::unique_ptr.

2016-10-21  Tom Tromey  <tom@tromey.com>

* mi/mi-main.c (mi_cmd_data_read_memory): Use gdb::unique_ptr.
Remove some cleanups.

Remove make_cleanup_restore_current_ui

This removes make_cleanup_restore_current_ui by converting the last
use.  The last use was in a few functions used to iterate over all
UIs.  This patch replaces these functions with a class, and arranges
for the class destructor to do the needed cleanup.

Record minimal symbols directly in reader.

This patch changes minimal symbol creation in two ways.  First, it
removes global variables in favor of members of minimal_symbol_reader.
Second, it changes functions like prim_record_minimal_symbol to be
member functions of minimal_symbol_reader.

2016-10-21  Tom Tromey  <tom@tromey.com>

Change minimal_symbol_reader to store objfile

This changes minimal_symbol_reader to require the objfile to be
passed to the constructor.  The class now records the objfile and
automatically uses it later in "install".

This is a minor cleanup that will come in useful in the next patch.
It is separate from the first patch to keep that one a bit simpler to
understand.

2016-10-21  Tom Tromey  <tom@tromey.com>

Introduce minimal_symbol_reader

This patch introduced minimal_symbol_reader, a RAII-based class which
replaces the current make_cleanup_discard_minimal_symbols.

2016-10-21  Tom Tromey  <tom@tromey.com>

Use scoped_restore for current_ui

This changes most uses of make_cleanup_restore_current_ui to use
scoped_restore.  The use in switch_thru_all_uis_init still remains;
that is dealt with in a later patch by replacing this iterator with a
real class.

2016-10-21  Tom Tromey  <tom@tromey.com>

* top.c (new_ui_command, wait_sync_command_done)

Use RAII to save and restore scalars

This patch replaces many (but not all) uses of
make_cleanup_restore_integer with a simple RAII-based template class.
It also removes the similar restore_execution_direction cleanup in
favor of this new class.  Subsequent patches will replace other
similar cleanups with this class.

The class is typically instantiated using make_scoped_restore.  This
allows for template argument deduction.

Fix symbol table file name on AIX

When xlc -qfuncsect or gcc -ffunction-sections options is used in AIX,
each function csect is associated with each psymtab, so each psymtab

gdb: no longer define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS

My gnulib fix at:
  https://lists.gnu.org/archive/html/bug-gnulib/2015-11/msg00010.html
was merged upstream meanwhile and our gnulib copy now includes it.

As a concidence, Kevin was telling me today that these macros are
causing a build problem on FreeBSD:

common/common-defs.h:47:0: error: "__STDC_CONSTANT_MACROS" redefined [-Werror]
  #define __STDC_CONSTANT_MACROS 1
  /usr/include/sys/cdefs.h:408:0: note: this is the location of the previous definition
  #define __STDC_CONSTANT_MACROS
(and a similar error for __STDC_LIMIT_MACROS)

The problem seems to be that we should be defining these input macros
before including any system header, but, we're not.

So let's just revert e063da67902e ([C++] Define __STDC_CONSTANT_MACROS
/ __STDC_LIMIT_MACROS for stdint.h).  If this causes a problem
somewhere, we can re-define the macros higher up in the file, before
system headers are included.

gdb/ChangeLog:
2016-10-18  Pedro Alves  <palves@redhat.com>

* common/common-defs.h (__STDC_CONSTANT_MACROS)
(__STDC_LIMIT_MACROS): Delete.

Update gnulib to current upstream master

I tried building gdb with G++ 4.7 and CXX="g++ -std=gnu+11", and that
tripped on a build error:

Updating gnulib to current master fixes it, since it brings in this
fix:

 http://lists.gnu.org/archive/html/bug-gnulib/2016-04/msg00000.html

Our last update was in August 2015.  This doesn't bring in much added
baggage, it's mostly bug fixes.  It pulled in the "limits-h" module as
automatic dependency, and given that looks potentially useful I added
it to the set of modules we require.

Tested on x86_64 Fedora 23, with g++ 4.7 and g++ 5.3, native and gdbserver.

Introduce gdb::unique_ptr

Many make_cleanup uses in the code base are best eliminated by using a
"owning" smart pointer to manage ownership of the resource
automatically.

The question is _which_ smart pointer.

GDB currently supports building with a C++03 compiler.  We have
std::auto_ptr in C++03, but, as is collective wisdom by now, that's
too easy to misuse, and has therefore been deprecated in C++11 and
finally removed in C++17.

It'd be nice to be able to use std::unique_ptr instead, which is the
modern, safe std::auto_ptr replacement in C++11.

In addition to extra safety -- moving (i.e., transfer of ownership of
the managed pointer between smart pointers) must be explicit --
std::unique_ptr has (among others) one nice feature that std::auto_ptr
doesn't --- ability to specify a custom deleter as template parameter.
In gdb's context, that allows easily creating a smart pointer for
memory allocated with xmalloc -- the smart pointer then knows to
release with xfree instead of delete.  This is particularly
interesting when managing objects allocated in C libraries, and also,
for C++-fying parts of GDB that interact with other parts that still
return objects allocated with xmalloc.

Since std::unique_ptr's API is quite nice, and eventually we'd like to
move to C++11, this patch adds a C++03-compatible smart pointer that
exposes the subset of the std::unique_ptr API that we're interested
in.  An advantage is that whenever we start requiring C++11, we won't
have to learn a new API.  Meanwhile, this allows continuing to support
building with a C++03 compiler.

Since C++03 doesn't support rvalue references (boost gets close to
emulating them, but it's not fully transparent to user code), the
C++03 std::unique_ptr emulation here doesn't try hard to prevent
accidentally moving, which is where most of complication of a more
thorough emulation would be.  Instead, we rely on the fact that GDB
will be usually compiled with a C++11 compiler, and use the real
std::unique_ptr in that case to catch such accidental moves.  IOW, the
goal here is to allow code that would be correct using std::unique_ptr
to be equally correct in C++03 mode, and, just as efficient.

The C++03 version was originally based on GCC 7.0's std::auto_ptr and
then heavily customized to behave more like C++11's std::unique_ptr:

   - Support for custom (stateless) deleters.  (Support for stateful
     deleters could be added, if necessary.)

   - unique_ptr<T[]> partial specialization (auto_ptr<T> does not know
     to use delete[]).

   - Support for all of 'ptr != NULL', 'ptr == NULL' and 'if (ptr)'
     using the safe bool idiom to emulate C++11's explicit bool
     operator.

   - There's no nullptr in C++03, so this allows initialization and
     assignment from NULL instead (std::auto_ptr allows neither).

   - Variable names un-uglified (ie., no leading __ prefix everywhere).

   - Formatting made to follow GDB's coding conventions, including
     comment style.

   - Converting "move" constructors done differently in order to truly
     support:

      unique_ptr<Derived> func_returning_unique_ptr (.....);
      ...
      unique_ptr<Base> ptr = func_returning_unique_ptr (.....);

At this point, it no longer shares much at all with the original file,
but, that's the history.

See comments in the code to find out more.

I thought of putting the "emulation" / shim in the "std" namespace, so
that when we start requiring C++11 at some point, no actual changes to
users of the smart pointer throughout would be necessary.  Putting
things in the std namespace is technically undefined, however in
practice it doesn't cause any issue with any compiler.  However,
thinking that people might be confused with seeing std::unique_ptr and
thinking that we're actually requiring C++11 already, I put the new
types in the "gdb" namespace instead.

For managing xmalloc pointers, this adds a gdb::unique_xmalloc_ptr<T>
"specialization" with a custom xfree deleter.

No actual use of any smart pointer is introduced in this patch.
That'll be done in following patches.

Tested (along with the rest of the series) on:

 - NetBSD 5.1 (gcc70 on the compile farm), w/ gcc 4.1.3
 - x86-64 Fedora 23, gcc 5.3.1 (gnu++03)
 - x86-64 Fedora 23, and gcc 7.0 (gnu++14)

This is a regression caused by commit cda6c55bd399 (Turn wchar

gdb/charset.h, while before it was only used in gdb/charset.c.

gdb/charset.c, under #ifdef PHONY_ICONV, does:

 #undef iconv_t
 #define iconv_t int

indicate is the instruction uses a long immediate (LIMM).  In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions.  However, for the ARCv2 processors,
this LIMM indicator is 0x1E.

Convert tid_range_parser and get_number_or_range to classes

This converts tid_range_parser and get_number_or_range to be classes.
The various tid_range_parser_* and get_number_or_range_* functions
become methods on the respective classes.  Then it updates the users
to follow.

The rationale for the change is that this provides better
encapsulation.  For example, this forced me to think of a better
interface between tid_range_parser and get_number_or_range, since the
former peeked into the latter's internals a bit too much.  That ended
up resulting mostly in these two not-just-straight-1-1 changes:

  void
 -tid_range_parser_skip (struct tid_range_parser *parser)
 +tid_range_parser::skip_range ()
  {
 ...

 -  tid_range_parser_init (parser, parser->range_parser.end_ptr,
 -  parser->default_inferior);
 +  m_range_parser.skip_range ();
 +  init (m_range_parser.string (), m_default_inferior);
  }

 and:

    /* If we successfully parsed a thread number or finished parsing a
       thread range, switch back to assuming the next TID is
       inferior-qualified.  */
 -  if (parser->range_parser.end_ptr == NULL
 -      || parser->range_parser.string == parser->range_parser.end_ptr)
 +  if (!m_range_parser.in_range ())
      {

For the same reason (encapsulation), this moves the enum
tid_range_state definition to within the tid_parser class's scope,
since that is private implementation detail.

While at it, switch to use "bool" for booleans.

Fixup gdb.python/py-value.exp for bare-metal aarch64-elf

I noticed that testing aarch64-elf gdb with a physical board
ran into issues with gdb.python/py-value.exp. Further investigation showed
that we were actually trying to dereference a NULL pointer (argv) when trying
to access argv[0].

Being bare-metal, argv is not guaranteed to be valid. So we need to make sure
argv is sane before accessing argv[0].

The following patch fixes up the test program to check for a NULL argv and also
improves the testcase a bit so it doesn't have to work with a hardcoded argc
value.

Regression-tested on x86-64 Ubuntu 16.04.
