Nitika Achra 3112ed9799 Support for DWARF5 location lists entries 
This patch handles DW_LLE_base_addressx, DW_LLE_startx_length and
DW_LLE_start_length.

Tested by running the testsuite before and after the patch and there is
no increase in the number of test cases that fails. Tested with both
-gdwarf-4 and -gdwarf-5 flags. Also tested -gslit-dwarf along with
-gdwarf-4 as well as -gdwarf5 flags.

This is an effort to support DWARF5 in gdb.

gdb/ChangeLog:

	* dwarf2loc.c (decode_debug_loclists_addresses): Handle
	DW_LLE_base_addressx, DW_LLE_startx_length, DW_LLE_start_length.

Simon Marchi 6c2659886f gdb: add back declarations for _initialize functions 
I'd like to enable the -Wmissing-declarations warning.  However, it
warns for every _initialize function, for example:

      CXX    dcache.o
    /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
    /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
     _initialize_dcache (void)
     ^~~~~~~~~~~~~~~~~~

The only practical way forward I found is to add back the declarations,
which were removed by this commit:

    commit 481695ed5f
    Author: John Baldwin <jhb@FreeBSD.org>
    Date:   Sat Sep 9 11:02:37 2017 -0700

        Remove unnecessary function prototypes.

I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

Tom Tromey d5a22e77b5 Remove gdbarch_bits_big_endian 
From what I can tell, set_gdbarch_bits_big_endian has never been used.
That is, all architectures since its introduction have simply used the
default, which is simply check the architecture's byte-endianness.

Because this interferes with the scalar_storage_order code, this patch
removes this gdbarch setting entirely.  In some places,
type_byte_order is used rather than the plain gdbarch.

Peeter Joot 34877895ca Adjust byte order variable display/change if DW_AT_endianity is present. 
- Rationale:
It is possible for compilers to indicate the desired byte order
interpretation of scalar variables using the DWARF attribute:
   DW_AT_endianity

A type flagged with this variable would typically use one of:
   DW_END_big
   DW_END_little
which instructs the debugger what the desired byte order interpretation
of the variable should be.

The GCC compiler (as of V6) has a mechanism for setting the desired byte
ordering of the fields within a structure or union.  For, example, on a
little endian target, a structure declared as:
   struct big {
       int v;
       short a[4];
   } __attribute__( ( scalar_storage_order( "big-endian" ) ) );
could be used to ensure all the structure members have a big-endian
interpretation (the compiler would automatically insert byte swap
instructions before and after respective store and load instructions).

- To reproduce
GCC V8 is required to correctly emit DW_AT_endianity DWARF attributes
in all situations when the scalar_storage_order attribute is used.

A fix for (dwarf endianity instrumentation) for GCC V6-V7 can be found
in the URL field of the following PR:
   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82509

- Test-case:
A new test case (testsuite/gdb.base/endianity.*) is included with this
patch.

Manual testing for mixed endianity code has also been done with GCC V8.
See:
   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82509#c4

- Observed vs. expected:

Without this change, using scalar_storage_order that doesn't match the
target, such as

struct otherendian
{
  int v;
} __attribute__( ( scalar_storage_order( "big-endian" ) ) );

would behave like the following on a little endian target:

   Breakpoint 1 at 0x401135: file endianity.c, line 41.
   (gdb) run
   Starting program: /home/pjoot/freeware/t/a.out
   Missing separate debuginfos, use: debuginfo-install glibc-2.17-292.el7.x86_64

   Breakpoint 1, main () at endianity.c:41
   41        struct otherendian o = {3};
   (gdb) n
   43        do_nothing (&o); /* START */
   (gdb) p o
   $1 = {v = 50331648}
   (gdb) p /x
   $2 = {v = 0x3000000}

whereas with this gdb enhancement we can access the variable with the user
specified endianity:

   Breakpoint 1, main () at endianity.c:41
   41        struct otherendian o = {3};
   (gdb) p o
   $1 = {v = 0}
   (gdb) n
   43        do_nothing (&o); /* START */
   (gdb) p o
   $2 = {v = 3}
   (gdb) p o.v = 4
   $3 = 4
   (gdb) p o.v
   $4 = 4
   (gdb) x/4xb &o.v
   0x7fffffffd90c: 0x00    0x00    0x00    0x04

(observe that the 4 byte int variable has a big endian representation in the
 hex dump.)

Andrew Burgess 9a49df9d4b gdb: Carry default property type around with dynamic properties 
This commit is preparation for the next one, with the aim of better
supporting signed dynamic properties on targets where the address size
specified in the DWARF headers is smaller than a CORE_ADDR, for
example debugging an i386 application on x86-64.

Consider this small Fortran program 'bounds.f90':

    program test
      integer, allocatable :: array (:)
      allocate (array (-5:5))
      array(3) = 1
    end program test

Compiled with 'gfortran -m32 -g3 -O0 -o bounds bounds.f90'.  The DWARF
for 'array' looks like this:

   <2><97>: Abbrev Number: 10 (DW_TAG_variable)
      <98>   DW_AT_name        : (indirect string, offset: 0x0): array

   <2><ce>: Abbrev Number: 0

If we look at the DW_AT_lower_bound attribute, which will become a
dynamic property that GDB evaluates when needed by calling
dwarf2_evaluate_property.

The process of evaluating a dynamic property requires GDB to execute
each DW_OP_* operation, the results of these operations is held on a
stack of 'struct value *'s.

When the entire expression is evaluated the result is on top of the
stack.

If we look at DW_AT_lower_bound then the last operation is
DW_OP_deref, this loads a signed address the size of which matches the
DWARF address size, and so in our i386 on x86-64 situation, the top of
the stack will be a signed 4-byte value.

The problem is how these values are fetched from the stack.  Currently
they are always fetched by a call to dwarf_expr_context::fetch_address,
which converts the value to an unsigned value with a length matching
the values current length, before converting to a CORE_ADDR.  This
means we loose the signed nature of the property.

I wonder if the best solution for dealing with signed properties will
be to move away from an over reliance on fetch_address, and instead
come up with a new solution that considers the current type of the
value on the stack, and the type that the value needs to become;
basically a solution built around casting rather than assuming we
always want an address.

However, before we can start to even think about moving away from
fetch_address, there is a more urgent issue to fix, which is we don't
currently know what type each property should be.  We just hold the
value of the property in a CORE_ADDR as returned by fetch_address, and
rely on higher level code (outside of the DWARF expression evaluation
code) to fix things up for us.  This is what this patch aims to
address.

When creating a dynamic property (see attr_to_dynamic_prop in
dwarf2read.c) we can sometimes figure out the type of a property; if
the property is a reference to another DIE then it will have a
DW_AT_type attribute.

However, the DW_AT_lower_bound case above isn't a reference to another
DIE, it's just a DWARF expression.  We don't have any indication for
what type the property should have.

Luckily, the DWARF spec helps us out, for the lower and upper bounds
5.13 of the DWARFv5 spec tells us that without any other type
information the bounds are signed integers the same size as a DWARF
address.

It is my belief that we can find a suitable default type for every
dynamic property, either specified explicitly in the DWARF spec, or we
can infer an obvious choice if the spec doesn't help us.

This commit extends the creation of all dynamic properties to include
suggesting a suitable default type, all dynamic properties now always
carry their type around with them.

In later commits we can use this property type to ensure that the
value we extract from the DWARF stack is handled in a suitable manor
to correctly maintain its sign extension.

There should be no user visible changes from this commit.  The actual
fix to correctly support negative array bounds will come later.

Tom Tromey 268a13a5a3 Rename common to gdbsupport 
This is the next patch in the ongoing series to move gdbsever to the
top level.

This patch just renames the "common" directory.  The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top.  This approach makes the patches a bit
more tractable.

I chose the name "gdbsupport" for the directory.  However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

Tested by the buildbot.

Tom Tromey 587ee17bd4 Don't declare read_unsigned_leb128 in defs.h 
I noticed that read_unsigned_leb128 is declared in defs.h.  There's no
reason this should be here, so this patch moves it to dwarf2read.h.

Tom Tromey 988915ee7b Fix VLA printing for Ada 
While looking at a different Ada problem, I found that printing a
record containing a VLA did not work properly.

I tracked the problem down to dwarf2_evaluate_property trying, and
failing, to compare two types that differed only in qualifiers.

This patch changes dwarf2_evaluate_property to ignore qualifiers when
comparing types.

Tested on x86-64 Fedora 29.

Ali Tamur 336d760da6 Support for DW_OP_addrx and DW_FORM_addrx tags 
DW_OP_addrx is the new name of DW_OP_GNU_addr_index, and DW_FORM_addrx
is the name of DW_FORM_addr_index in the Dwarf 5 standard. This is a small
step towards supporting Dwarf 5 in gdb.

Note: I could not find any tests specifically for *_GNU_addr_index, and
I did not add any new tests, please advise.

Tom Tromey eedc3f4f0a Replace throw_exception with throw in some cases 
This replaces throw_exception with "throw;" when possible.  This was
written by script.  The rule that is followed is that uses of the
form:

   catch (... &name)
     {
       ...
       throw_exception (name);
     }

... can be rewritten.  This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

Tom Tromey 230d2906b9 Rename gdb exception types 
This renames the gdb exception types.  The old types were only needed
due to the macros in common-exception.h that are now gone.

needed, so this patch removes it entirely.

Tom Tromey 4de283e4b5 Revert the header-sorting patch 
Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).

So, I'm reverting the patch.  I may try again after fixing the issues
pointed out.

Tom Tromey d55e5aa6b2 Sort includes for files gdb/[a-f]*.[chyl]. 
This patch sorts the include files for the files [a-f]*.[chyl].
The patch was written by a script.

Tested by the buildbot.

I will follow up with patches to sort the remaining files, by sorting
a subset, testing them, and then checking them in.

Joel Brobecker 42a4f53d2b Update copyright year range in all GDB files. 
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

gdb/ChangeLog:

	Update copyright year range in all GDB files.
 2019-01-01 10:01:51 +04:00
Joel Brobecker a99bc3d23c delete ada-lang.c::move_bits, sharing and re-using copy_bitwise instead 
This patch deletes ada-lang.c's move_bits function entirely, and
replaces all calls to it by calls to copy_bitwise instead. Because
the latter function was declared locally inside dwarf2loc.c, this
patch also move the function to a common area, and makes it non-static.

gdb/ChangeLog:

        * ada-lang.c (move_bits): Delete. Update all callers to use
        copy_bitwise instead.
        * dwarf2loc.c (copy_bitwise, bits_to_str::bits_to_str)
        (selftests::check_copy_bitwise, selftests::copy_bitwise_tests):
        Move from here to utils.c.
        (_initialize_dwarf2loc): Remove call to register copy_bitwise
        selftests.
        * utils.h (copy_bitwise): Add declaration.
        * utils.c (copy_bitwise, bits_to_str::bits_to_str)
        (selftests::check_copy_bitwise, selftests::copy_bitwise_tests):
        Moved here from dwarf2loc.c.
        (_initialize_utils): Register copy_bitwise selftests.

Tested on x86_64-linux, no regression. Also tested using AdaCore's
testsuite on a collection of small endian and big endian platforms.

Tom Tromey b926417afa Simple -Wshadow=local fixes 
This fixes all the straightforward -Wshadow=local warnings in gdb.  A
few standard approaches are used here:

* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
  including the special case of moving a declaration into a loop header.

I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

Simon Marchi d82b3862f1 compile: Remove non-const reference parameters 
As mentioned here:

  https://sourceware.org/gdb/wiki/Internals%20GDB-C-Coding-Standards#Avoid_non-const_reference_parameters.2C_use_pointers_instead

we prefer to avoid non-const references.  This patch changes the
non-const references I could find in the compile/ directory, either by
making them rvalue-reference (&&) or changing them to pointers.

I'd say all the changes are pretty obvious, except the one in
compile_cplus_instance::enter_scope which might require more attention.

Tom de Vries e4a62c65fa [gdb/exp] Handle DW_OP_GNU_variable_value refs to abstract dies 
Consider a vla variable 'a' in function f1:
...
 <2><1a7>: Abbrev Number: 11 (DW_TAG_variable)
    <1a8>   DW_AT_description : a
    <1aa>   DW_AT_abstract_origin: <0x311>
...
with abstract origin 'a':
...
 <2><311>: Abbrev Number: 3 (DW_TAG_variable)
    <312>   DW_AT_name        : a
    <317>   DW_AT_type        : <0x325>
...
and inherited abstract vla type:
...
 <1><325>: Abbrev Number: 9 (DW_TAG_array_type)
    <326>   DW_AT_type        : <0x33a>
 <2><32e>: Abbrev Number: 10 (DW_TAG_subrange_type)
    <32f>   DW_AT_type        : <0x2ea>
    <333>   DW_AT_upper_bound : 5 byte block: fd 1b 3 0 0
                                (DW_OP_GNU_variable_value: <0x31b>)
...
where the upper bound refers to this artificial variable D.1922 without location
attribute:
...
 <2><31b>: Abbrev Number: 8 (DW_TAG_variable)
    <31c>   DW_AT_description : (indirect string, offset: 0x39a): D.1922
    <320>   DW_AT_type        : <0x2ea>
    <324>   DW_AT_artificial  : 1
...

Currently, when we execute "p sizeof (a)" in f1, the upper bound is calculated
by evaluating the DW_OP_GNU_variable_value expression referring to D.1922, but
since that die doesn't have a location attribute, we get:
...
value has been optimized out
...

However, there's also artificial variable D.4283 that is sibling of vla
variable 'a', has artificial variable D.1922 as abstract origin, and has a
location attribute:
...
 <2><1ae>: Abbrev Number: 12 (DW_TAG_variable)
    <1af>   DW_AT_description : (indirect string, offset: 0x1f8): D.4283
    <1b3>   DW_AT_abstract_origin: <0x31b>
    <1b7>   DW_AT_location    : 11 byte block: 75 1 8 20 24 8 20 26 31 1c 9f
                                (DW_OP_breg5 (rdi):1; DW_OP_const1u: 32;
				 DW_OP_shl; DW_OP_const1u: 32; DW_OP_shra;
				 DW_OP_lit1; DW_OP_minus; DW_OP_stack_value)
...

The intended behaviour for DW_OP_GNU_variable_value is to find a die that
refers to D.1922 as abstract origin, has a location attribute and is
'in scope', so the expected behaviour is:
...
$1 = 6
...

The 'in scope' concept can be thought of as variable D.1922 having name
attribute "D.1922", and variable D.4283 inheriting that attribute, resulting
in D.4283 being declared with name "D.1922" alongside vla a in f1, and when we
lookup "DW_OP_GNU_variable_value D.1922", it should work as if we try to find
the value of a variable named "D.1922" on the gdb command line using
"p D.1922", and we should return the value of D.4283.

This patch fixes the case described above, by:
- adding a field abstract_to_concrete to struct dwarf2_per_objfile,
- using that field to keep track of which concrete dies are instances of an
  abstract die, and
- using that information when getting the value DW_OP_GNU_variable_value.

Build and reg-tested on x86_64-linux.

Kevin Buettner 2b1ffcfd6f Use BLOCK_ENTRY_PC in place of most uses of BLOCK_START 
This change/patch substitues BLOCK_ENTRY_PC for BLOCK_START in
places where BLOCK_START is used to obtain the address at which
execution should enter the block.  Since blocks can now contain
non-contiguous ranges, the BLOCK_START - which is still be the
very lowest address in the block - might not be the same as
BLOCK_ENTRY_PC.

There is a change to infrun.c which is less obvious and less mechanical.
I'm posting it as a separate patch.

Kevin Buettner a6b786da4e Add support for DW_OP_GNU_variable_value 
This patch adds support for DW_OP_GNU_variable_value to GDB.

Jakub Jelinek provides a fairly expansive discussion of this DWARF
expression opcode in his GCC patch...

    https://gcc.gnu.org/ml/gcc-patches/2017-02/msg01499.html

It has also been proposed for addition to the DWARF Standard:

    http://www.dwarfstd.org/ShowIssue.php?issue=161109.2

If compiled with a suitable version of GCC, the test case associated
with GCC Bug 77589 uses DW_OP_GNU_variable_value in a DW_AT_byte_stride
expression.  Here's a link to the bug:

    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77589

This is what the DWARF looks like.  Look at the last line, which has
the DW_AT_byte_stride expression:

 <2><e1>: Abbrev Number: 12 (DW_TAG_variable)
    <e2>   DW_AT_name        : (indirect string, offset: 0x115): span.0
    <e6>   DW_AT_type        : <0x2e>
    <ea>   DW_AT_artificial  : 1
    <ea>   DW_AT_location    : 3 byte block: 91 b0 7f 	(DW_OP_fbreg: -80)
 ...
 <2><178>: Abbrev Number: 18 (DW_TAG_subrange_type)
    <179>   DW_AT_lower_bound : 4 byte block: 97 23 20 6 	(DW_OP_push_object_address; DW_OP_plus_uconst: 32; DW_OP_deref)
    <17e>   DW_AT_upper_bound : 4 byte block: 97 23 28 6 	(DW_OP_push_object_address; DW_OP_plus_uconst: 40; DW_OP_deref)
    <183>   DW_AT_byte_stride : 10 byte block: 97 23 18 6 fd e1 0 0 0 1e 	(DW_OP_push_object_address; DW_OP_plus_uconst: 24; DW_OP_deref; DW_OP_GNU_variable_value: <0xe1>; DW_OP_mul)

A patch to readelf, which I'm also submitting, is required to do this
decoding.

I found that GDB gave me the correct answer for "p c40pt(2)" once I
(correctly) implemented DW_OP_GNU_variable_value.

I also have test case (later in this series) which uses the DWARF
assembler and, therefore, do not rely on having a compiler with this
support.

gdb/ChangeLog:

	* dwarf2expr.h (struct dwarf_expr_context): Add virtual method
	dwarf_variable_value.
	* dwarf2-frame.c (class dwarf_expr_executor):
	Add override for dwarf_variable_value.
	* dwarf2loc.c (class dwarf_evaluate_loc_desc): Likewise.
	(class symbol_needs_eval_context): Likewise.
	(indirect_synthetic_pointer): Add forward declaration.
	(sect_variable_value): New function.
	(dwarf2_compile_expr_to_ax): Add case for DW_OP_GNU_variable_value.
	* dwarf2expr.c (dwarf_expr_context::execute_stack_op): Add case
	for DW_OP_GNU_variable_value.

Tom de Vries 16f808ec99 [gdb/exp] Fix exception when printing optimized out vla 
When compiling vla-optimized-out.c with -O3 and a recent gcc, and trying to
print the vla a in f1, we run into this gdb exception:
...
Cannot find matching parameter at DW_TAG_call_site 0x4003be at main
...

This is a regression introduced by 42dc7699a2 "[gdb/exp] Fix printing of type
of optimized out vla".

This patch fixes the regression by wrapping the ctx.eval call in
dwarf2_locexpr_baton_eval in try/catch, similar to what is done in
dwarf2_evaluate_loc_desc_full.

Build and reg-tested on x86_64-linux.

2018-07-25  Tom de Vries  <tdevries@suse.de>

	* dwarf2loc.c (dwarf2_locexpr_baton_eval): Wrap ctx.eval call in
	try/catch.

	* gdb.base/vla-optimized-out-o3.exp: New file.  Reuse
	vla-optimized-out.c.

Tom Tromey b98664d386 Remove symfile_complaints 
The complaint system seems to allow for multiple different complaint
topics.  However, in practice only symfile_complaints has ever been
defined.  Seeing that complaints.c dates to 1992, and that no new
complaints have been added in the intervening years, I think it is
reasonable to admit that complaints are specifically related to
debuginfo reading.

This patch removes symfile_complaints and updates all the callers.
Some of these spots should perhaps be calls to warning instead, but I
did not make that change.

Tom Tromey bbfa6f0086 Use new_reference for struct value 
value_incref returned its argument just as a convenience, which in the
end turned out to only be used in precisely the cases where
new_reference helps.  So, this patch changes value_incref to return
void and changes some value-using code to use new_reference.

I also noticed that the comments for value_incref and value_decref
were swapped, so this patch fixes those.

Tom Tromey 632e107b32 Enable -Wsuggest-override 
I noticed the existence of -Wsuggest-override and so this patch
enables it for gdb.  It found a few spots that could use "override".
Also I went ahead and removed all uses of the "OVERRIDE" macro.

Using override is beneficial because it makes it harder to change a
base class and then forget to change a derived class.

Tested by the buildbot.

Tom Tromey 22bc8444e6 Introduce a gdb_ref_ptr specialization for struct value 
struct value is internally reference counted and so, while it also has
some ownership rules unique to it, it makes sense to use a gdb_ref_ptr
when managing it automatically.

This patch removes the existing unique_ptr specialization in favor of
a reference-counted pointer.  It also introduces two other
clarifications:

1. Rename value_free to value_decref, which I think is more in line
   with what the function actually does; and

2. Change release_value to return a gdb_ref_ptr.  This change allows
   us to remove the confusing release_value_or_incref function,
   primarily by making it much simpler to reason about the result of
   release_value.

Simon Marchi 798a7429f9 Remove some unused variables 
This patch removes some unused variables, found with -Wunused.  I have
not removed everything reported by -Wunused, because some expressions
such as

  struct type *arg_type = check_typedef (value_type);

in bfin-tdep.c could have an unexpected but important side-effect.  I
removed others that I considered more low-risk, such as:

  struct gdbarch *gdbarch = get_objfile_arch (objfile);

Simon Marchi 1526853e34 Add selftests run filtering 
With the growing number of selftests, I think it would be useful to be
able to run only a subset of the tests.  This patch associates a name to
each registered selftest.  It then allows doing something like:

  (gdb) maintenance selftest aarch64
  Running self-tests.
  Running selftest aarch64-analyze-prologue.
  Running selftest aarch64-process-record.
  Ran 2 unit tests, 0 failed

or with gdbserver:

  ./gdbserver --selftest=aarch64

In both cases, only the tests that contain "aarch64" in their name are
ran.  To help validate that the tests you want to run were actually ran,
it also prints a message with the test name before running each test.

Right now, all the arch-dependent tests are registered as a single test
of the selftests.  To be able to filter those too, I made them
"first-class citizen" selftests.  The selftest type is an interface,
with different implementations for "simple selftests" and "arch
selftests".  The run_tests function simply iterates on that an invokes
operator() on each test.

I changed the tests data structure from a vector to a map, because

  - it allows iterating in a stable (alphabetical) order
  - it allows to easily verify if a test with a given name has been
    registered, to avoid duplicates

There's also a new command "maintenance info selftests" that lists the
registered selftests.

Simon Marchi 1e46716193 Make dwarf_expr_piece::pieces an std::vector 
Change the manually managed array dwarf_expr_piece::piece with an
std::vector.  After passing the pieces array to allocate_piece_closure,
dwarf2_evaluate_loc_desc_full doesn't need that data anymore.  We can
therefore move the content of the vector to avoid copying it.

Tom Tromey 0327869232 Fix size check in dwarf2_evaluate_loc_desc_full 
This Rust bug report:

https://github.com/rust-lang/rust/issues/41970

noted an error from gdb.  What is happening here (for me, the original
report had a different error) is that a pieced DWARF expression is not
writing to every byte in the resulting value.  GDB errors in this
case.  However, it seems to me that it is always valid to write fewer
bytes; the issue comes from writing too many -- that is, the test is
reversed.  The test was also checking the sub-object, but this also
seems incorrect, as it's expected for the expression to write the
entirety of the enclosing object.  So, this patch reverses the test
and applies it to the outer type, not the subobject type.

Regtested on the buildbot.

Pedro Alves 8268c77870 Eliminate make_cleanup_obstack_free, introduce auto_obstack 
This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.

These changes in the parsers may not be obvious:

 -  obstack_init (&name_obstack);
 -  make_cleanup_obstack_free (&name_obstack);
 +  name_obstack.clear ();

Here, the 'name_obstack' variable is a global.  The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts.  I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.

The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases.  I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

Pedro Alves d5722aa2fe Introduce gdb::byte_vector, add allocator that default-initializes 
In some cases we've been replacing heap-allocated gdb_byte buffers
managed with xmalloc/make_cleanup(xfree) with gdb::vector<gdb_byte>.
That usually pessimizes the code a little bit because std::vector
value-initializes elements (which for gdb_byte means
zero-initialization), while if you're creating a temporary buffer,
you're most certaintly going to fill it in with some data.  An
alternative is to use

  unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);

but it looks like that's not very popular.

Recently, a use of obstacks in dwarf2read.c was replaced with
std::vector<gdb_byte> and that as well introduced a pessimization for
always memsetting the buffer when it's garanteed that the zeros will
be overwritten immediately.  (see dwarf2read.c change in this patch to
find it.)

So here's a different take at addressing this issue "by design":

#1 - Introduce default_init_allocator<T>

I.e., a custom allocator that does default construction using default
initialization, meaning, no more zero initialization.  That's the
default_init_allocation<T> class added in this patch.

See "Notes" at
<http://en.cppreference.com/w/cpp/container/vector/resize>.

#2 - Introduce def_vector<T>

I.e., a convenience typedef, because typing the allocator is annoying:

  using def_vector<T> = std::vector<T, gdb::default_init_allocator<T>>;

#3 - Introduce byte_vector

Because gdb_byte vectors will be the common thing, add a convenience
"byte_vector" typedef:

  using byte_vector = def_vector<gdb_byte>;

which is really the same as:

  std::vector<gdb_byte, gdb::default_init_allocator<gdb_byte>>;

The intent then is to make "gdb::byte_vector" be the go-to for dynamic
byte buffers.  So the less friction, the better.

#4 - Adjust current code to use it.

To set the example going forward.  Replace std::vector uses and also
unique_ptr<byte[]> uses.

One nice thing is that with this allocator, for changes like these:

  -std::unique_ptr<byte[]> buf (new gdb_byte[some_size]);
  +gdb::byte_vector buf (some_size);
   fill_with_data (buf.data (), buf.size ());

the generated code is the same as before.  I.e., the compiler
de-structures the vector and gets rid of the unused "reserved vs size"
related fields.

The other nice thing is that it's easier to write
  gdb::byte_vector buf (size);
than
  std::unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);
or even (C++14):
  auto buf = std::make_unique<gdb_byte[]> (size); // zero-initializes...

#5 - Suggest s/std::vector<gdb_byte>/gdb::byte_vector/ going forward.

Note that this commit actually fixes a couple of bugs where the current
code is incorrectly using "std::vector::reserve(new_size)" and then
accessing the vector's internal buffer beyond the vector's size: see
dwarf2loc.c and charset.c.  That's undefined behavior and may trigger
debug mode assertion failures.  With default_init_allocator,
"resize()" behaves like "reserve()" performance wise, in that it
leaves new elements with unspecified values, but, it does that safely
without triggering undefined behavior when you access those values.

So far write_pieced_value uses write_memory when writing memory pieces to

watchpoint value.  In such a case write_memory_with_notification should be
used instead, so that memory_changed observers get notified.
