f6efe3f842 Introduce gdbarch_num_cooked_regs
The expression

  gdbarch_num_regs (gdbarch) + gdbarch_num_pseudo_regs (gdbarch)

is used quite often to find the number of cooked registers (raw + pseudo
registers).  This patch introduces gdbarch_num_cooked_regs, which does
the equivalent.  It substantially reduces required wrapping in some
places, so should improve readability.

There is a for loop in m68hc11_frame_unwind_cache that had iterated
until (the equivalent of) gdbarch_num_cooked_regs (gdbarch) - 1.  During
review, we concluded that this is most likely an off-by-one mistake, so
I replaced it with gdbarch_num_cooked_regs (gdbarch).

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.

23be8da739 Logical short circuiting with argument lists
When evaluating Fortran expressions such as the following:

	print truth_table(1,1) .OR. truth_table(2,1)

where truth_table(1,1) evaluates to true, the debugger would report that
it could not perform substring operations on this type. This patch
addresses this issue.

Investigation revealed that EVAL_SKIP was not being handled correctly
for all types serviced by the OP_F77_UNDETERMINED_ARGLIST case in
evaluate_subexp_standard. While skipping an undetermined argument list
the type is resolved to be an integer (as this is what evaluate_subexp
returns when skipping) and so it was not possible to delegate to the
appropriate case (e.g. array, function call).

The solution implemented here updates OP_VAR_VALUE to return correct
type information when skipping. This way OP_F77_UNDETERMINED_ARGLIST
can delegate the skipping to the appropriate case or routine, which
should know how to skip/evaluate the type in question.

koenig.exp was updated to include a testcase which exercises the
modified skip logic in OP_VAR_VALUE, as it falls through from
OP_ADL_FUNC.

This patch has been tested for regressions with GCC 7.3 on aarch64,
ppc64le and x86_64.

gdb/ChangeLog:

	* eval.c (skip_undetermined_arglist): Skip argument list helper.
	(evaluate_subexp_standard): Return a dummy type when
	honoring EVAL_SKIP in OP_VAR_VALUE and handle skipping in the
	OP_F77_UNDETERMINED_ARGLIST case.
	* expression.h (enum noside): Update comment.

2fabdf3381 gdb: Don't leak memory with TYPE_ALLOC / TYPE_ZALLOC
This patch started as an observation from valgrind that GDB appeared
to be loosing track of some memory associated with types.  An example
valgrind stack would be:

  24 bytes in 1 blocks are possibly lost in loss record 419 of 5,361
     at 0x4C2EA1E: calloc (vg_replace_malloc.c:711)
     by 0x623D26: xcalloc (common-utils.c:85)
     by 0x623D65: xzalloc(unsigned long) (common-utils.c:95)
     by 0x72A066: make_function_type(type*, type**) (gdbtypes.c:510)
     by 0x72A098: lookup_function_type(type*) (gdbtypes.c:521)
     by 0x73635D: gdbtypes_post_init(gdbarch*) (gdbtypes.c:5439)
     by 0x727590: gdbarch_data(gdbarch*, gdbarch_data*) (gdbarch.c:5230)
     by 0x735B99: builtin_type(gdbarch*) (gdbtypes.c:5313)
     by 0x514D95: elf_rel_plt_read(minimal_symbol_reader&, objfile*, bfd_symbol**) (elfread.c:542)
     by 0x51662F: elf_read_minimal_symbols(objfile*, int, elfinfo const*) (elfread.c:1121)
     by 0x5168A5: elf_symfile_read(objfile*, enum_flags<symfile_add_flag>) (elfread.c:1207)
     by 0x8520F5: read_symbols(objfile*, enum_flags<symfile_add_flag>) (symfile.c:794)

When we look in make_function_type we find a call to TYPE_ZALLOC
(inside the INIT_FUNC_SPECIFIC macro).  It is this call to TYPE_ZALLOC
that is allocating memory with xcalloc, that is then getting lost.

The problem is tht calling TYPE_ALLOC or TYPE_ZALLOC currently
allocates memory from either the objfile obstack or by using malloc.
The problem with this is that types are allocated either on the
objfile obstack, or on the gdbarch obstack.

As a result, if we discard a type associated with an objfile then
auxiliary data allocated with TYPE_(Z)ALLOC will be correctly
discarded.  But, if we were ever to discard a gdbarch then any
auxiliary type data would be leaked.  Right now there are very few
places in GDB where a gdbarch is ever discarded, but it shouldn't hurt
to close down these bugs as we spot them.

This commit ensures that auxiliary type data is allocated from the
same obstack as the type itself, which should reduce leaked memory.

The one problem case that I found with this change was in eval.c,
where in one place we allocate a local type structure, and then used
TYPE_ZALLOC to allocate some space for the type.  This local type is
neither object file owned, nor gdbarch owned, and so the updated
TYPE_ALLOC code is unable to find an objstack to allocate space on.

My proposed solution for this issue is that the space should be
allocated with a direct call to xzalloc.  We could extend TYPE_ALLOC
to check for type->gdbarch being null, and then fall back to a direct
call to xzalloc, however, I think that making this rare case of a
local type require special handling is not a bad thing, this serves to
highlight that clearing up the memory will require special handling
too.

This special case of a local type is interesting as the types owner
field (contained within the main_type) is completely null.  While
reflecting on this I looked at how types use the get_type_arch
function.  It seems clear that, based on how this is used, it is never
intended that null will be returned from this function.  This only
goes to reinforce, how locally alloctaed types, with no owner, are
both special, and need to be handled carefully.  To help spot errors
earlier, I added an assert into get_type_arch that the returned arch
is not null.

Inside gdbarch.c I found a few other places where auxiliary type data
was being allocated directly on the heap rather than on the types
obstack.  I have fixed these to call TYPE_ALLOC now.

Finally, it is worth noting that as we don't clean up our gdbarch
objects yet, then this will not make much of an impact on the amount
of memory reported as lost at program termination time.  Memory
allocated for auxiliary type information is still not freed, however,
it is now on the correct obstack.  If we do ever start freeing our
gdbarch structures then the associated type data will be cleaned up
correctly.

Tested on X86-64 GNU/Linux with no regressions.

gdb/ChangeLog:

	* eval.c (fake_method::fake_method): Call xzalloc directly for a
	type that is neither object file owned, nor gdbarch owned.
	* gdbtypes.c (get_type_gdbarch): Add an assert that returned
	gdbarch is non-NULL.
	(alloc_type_instance): Allocate non-objfile owned types on the
	gdbarch obstack.
	(copy_type_recursive): Allocate TYPE_FIELDS and TYPE_RANGE_DATA
	using TYPE_ALLOC to ensure memory is allocated on the correct
	obstack.
	* gdbtypes.h (TYPE_ALLOC): Allocate space on either the objfile
	obstack, or the gdbarch obstack.
	(TYPE_ZALLOC): Rewrite using TYPE_ALLOC.

c8f2dc0dc9 gdb: Fix sizeof for dynamic types other than arrays
In commit:

   commit 37cc0caeca
   Date:   Wed Jul 18 13:38:35 2018 +0200
   [gdb/exp] Interpret size of vla with unknown size as <optimized out>

All dynamic types are treated as arrays in the 'sizeof' code path,
which means that structures can incorrectly be treated as arrays.
This can cause a failure in the gdb.base/vla-datatypes.exp test
script.

This commit adds a check that we do have an array before checking the
array bounds, and I also check that the array index type is dynamic
too.  This second check probably isn't strictly necessary, but
shouldn't hurt, a non-dynamic index type shouldn't have undefined high
bound.

gdb/ChangeLog:

	* eval.c (evaluate_subexp_for_sizeof): Check for array type before
	checking array bounds are defined.

37cc0caeca [gdb/exp] Interpret size of vla with unknown size as <optimized out>
At -O3 -g -gstrict-dwarf, gcc generates for an optimized out vla 'a' a
DW_TAG_variable with type DW_TAG_array_type containing one
DW_TAG_subrange_type, but without DW_AT_upper_bound or DW_AT_count, which
makes the upper bound value 'unknown':
...
	.uleb128 0x15   # (DIE (0x161) DW_TAG_variable)
        .long   0xec    # DW_AT_abstract_origin
        .long   0x170   # DW_AT_type
	...
        .uleb128 0xa    # (DIE (0x170) DW_TAG_array_type)
        .long   0x110   # DW_AT_type
        .long   0x17f   # DW_AT_sibling
        .uleb128 0x17   # (DIE (0x179) DW_TAG_subrange_type)
        .long   0xc6    # DW_AT_type
        .byte   0       # end of children of DIE 0x170
...

But gdb prints '0' for the size of 'a':
...
/gdb ./vla-1.exe -batch -ex "b f1" -ex "run" -ex "p sizeof(a)"
Breakpoint 1 at 0x4004c0: f1. (2 locations)

Breakpoint 1, f1 (i=<optimized out>) at vla-1.c:18
18      }
$1 = 0
...
while <optimized out> would be more appropriate.

This patch fixes that in evaluate_subexp_for_sizeof.

Build and reg-tested on x86_64-linux.

00431a78b2 Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support.

In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID.  E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines.  Or maybe we've loaded multiple
instances of the same core file.  Etc.

To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively.  I.e.,
each process_stratum instance has its own thread/process number space.

As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int.  E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.

In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid.  Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.

So that's what this patch does.  In a bit more detail:

- Changes a number of functions and methods to take a thread_info or
  inferior pointer instead of a ptid_t or int parameter.

- Changes a number of structure fields from ptid_t/int to inferior or
  thread_info pointers.

- Uses the inferior_thread() function whenever possible instead of
  inferior_ptid.

- Uses thread_info pointers directly when possible instead of the
  is_running/is_stopped etc. routines that require a lookup.

- A number of functions are eliminated along the way, such as:

  int valid_gdb_inferior_id (int num);
  int pid_to_gdb_inferior_id (int pid);
  int gdb_inferior_id_to_pid (int num);
  int in_inferior_list (int pid);

- A few structures and places hold a thread_info pointer across
  inferior execution, so now they take a strong reference to the
  (refcounted) thread_info object to avoid the thread_info pointer
  getting stale.  This is done in enable_thread_stack_temporaries and
  in the infcall.c code.

- Related, there's a spot in infcall.c where using a RAII object to
  handle the refcount would be handy, so a gdb::ref_ptr specialization
  for thread_info is added (thread_info_ref, in gdbthread.h), along
  with a gdb_ref_ptr policy that works for all refcounted_object types
  (in common/refcounted-object.h).

8b88a78e63 target_stack -> current_top_target() throughout
The recent C++ification of target_ops replaced references to the old
"current_target" squashed target throughout with references to a
"target_stack" pointer.  I had picked the "target_stack" name very
early in the multi-target work, and managed to stick with it, even
though it's a bit of a misnomer, since it isn't really a "target
stack" object, but a pointer into the current top target in the stack.
As I'm splitting more pieces off of the multi-target branch, I've come
to think that it's better to rename it now.  A following patch will
introduce a new class to represent a target stack, and "target_stack"
would be _its_ ideal name.  (In the branch, the class is called
a_target_stack to work around the clash.)

Thus this commit renames target_stack to current_top_target and
replaces all references throughout.  Also, while at it,
current_top_target is made a function instead of a pointer, to make it
possible to change its internal implementation without leaking
implementation details out.  In a couple patches, the implementation
of the function will change to refer to a target stack object, and
then further down the multi-target work, it'll change again to find
the right target stack for the current inferior.

e86ca25fd6 Remove TYPE_TAG_NAME
TYPE_TAG_NAME has been an occasional source of confusion and bugs.  It
seems to me that it is only useful for C and C++ -- but even there,
not so much, because at least with DWARF there doesn't seem to be any
way to wind up with a type where the name and the tag name are both
non-NULL and different.

So, this patch removes TYPE_TAG_NAME entirely.  This should save a
little memory, but more importantly, it simplifies this part of gdb.

A few minor test suite adjustments were needed.  In some situations
the new code does not yield identical output to the old code.

f6ac5f3d63 Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.

Unfortunately, there's no way to do a smooth transition.  ALL native
targets in the tree must be converted at the same time.  I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports.  Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.

* Implementation notes:

- The flattened current_target is gone.  References to current_target
  or current_target.beneath are replaced with references to
  target_stack (the top of the stack) directly.

- To keep "set debug target" working, this adds a new debug_stratum
  layer that sits on top of the stack, prints the debug, and delegates
  to the target beneath.

  In addition, this makes the shortname and longname properties of
  target_ops be virtual methods instead of data fields, and makes the
  debug target defer those to the target beneath.  This is so that
  debug code sprinkled around that does "if (debugtarget) ..."  can
  transparently print the name of the target beneath.

  A patch later in the series actually splits out the
  shortname/longname methods to a separate structure, but I preferred
  to keep that chance separate as it is associated with changing a bit
  the design of how targets are registered and open.

- Since you can't check whether a C++ virtual method is overridden,
  the old method of checking whether a target_ops implements a method
  by comparing the function pointer must be replaced with something
  else.

  Some cases are fixed by adding a parallel "can_do_foo" target_ops
  methods.  E.g.,:

    +  for (t = target_stack; t != NULL; t = t->beneath)
	 {
    -      if (t->to_create_inferior != NULL)
    +      if (t->can_create_inferior ())
	    break;
	 }

  Others are fixed by changing void return type to bool or int return
  type, and have the default implementation return false or -1, to
  indicate lack of support.

- make-target-delegates was adjusted to generate C++ classes and
  methods.

  It needed tweaks to grok "virtual" in front of the target method
  name, and for the fact that methods are no longer function pointers.
  (In particular, the current code parsing the return type was simple
  because it could simply parse up until the '(' in '(*to_foo)'.

  It now generates a couple C++ classes that inherit target_ops:
  dummy_target and debug_target.

  Since we need to generate the class declarations as well, i.e., we
  need to emit methods twice, we now generate the code in two passes.

- The core_target global is renamed to avoid conflict with the
  "core_target" class.

- ctf/tfile targets

  init_tracefile_ops is replaced by a base class that is inherited by
  both ctf and tfile.

- bsd-uthread

  The bsd_uthread_ops_hack hack is gone.  It's not needed because
  nothing was extending a target created by bsd_uthread_target.

- remote/extended-remote targets

  This is a first pass, just enough to C++ify target_ops.

  A later pass will convert more free functions to methods, and make
  remote_state be truly per remote instance, allowing multiple
  simultaneous instances of remote targets.

- inf-child/"native" is converted to an actual base class
  (inf_child_target), that is inherited by all native targets.

- GNU/Linux

  The old weird double-target linux_ops mechanism in linux-nat.c, is
  gone, replaced by adding a few virtual methods to linux-nat.h's
  target_ops, called low_XXX, that the concrete linux-nat
  implementations override.  Sort of like gdbserver's
  linux_target_ops, but simpler, for requiring only one
  target_ops-like hierarchy, which spares implementing the same method
  twice when we need to forward the method to a low implementation.
  The low target simply reimplements the target_ops method directly in
  that case.

  There are a few remaining linux-nat.c hooks that would be better
  converted to low_ methods like above too.  E.g.:

   linux_nat_set_new_thread (t, x86_linux_new_thread);
   linux_nat_set_new_fork (t, x86_linux_new_fork);
   linux_nat_set_forget_process

  That'll be done in a follow up patch.

- We can no longer use functions like x86_use_watchpoints to install
  custom methods on an arbitrary base target.

  The patch replaces instances of such a pattern with template mixins.
  For example memory_breakpoint_target defined in target.h, or
  x86_nat_target in x86-nat.h.

- linux_trad_target, MIPS and Alpha GNU/Linux

  The code in the new linux-nat-trad.h/c files which was split off of
  inf-ptrace.h/c recently, is converted to a C++ base class, and used
  by the MIPS and Alpha GNU/Linux ports.

- BSD targets

  The

    $architecture x NetBSD/OpenBSD/FreeBSD

  support matrix complicates things a bit.  There's common BSD target
  code, and there's common architecture-specific code shared between
  the different BSDs.  Currently, all that is stiched together to form
  a final target, via the i386bsd_target, x86bsd_target,
  fbsd_nat_add_target functions etc.

  This introduces new fbsd_nat_target, obsd_nat_target and
  nbsd_nat_target classes that serve as base/prototype target for the
  corresponding BSD variant.

  And introduces generic i386/AMD64 BSD targets, to be used as
  template mixin to build a final target.  Similarly, a generic SPARC
  target is added, used by both BSD and Linux ports.

- bsd_kvm_add_target, BSD libkvm target

  I considered making bsd_kvm_supply_pcb a virtual method, and then
  have each port inherit bsd_kvm_target and override that method, but
  that was resulting in lots of unjustified churn, so I left the
  function pointer mechanism alone.

8388016d7f Calling ifunc functions when target has no debug info but resolver has
After the previous patch, on Fedora 27 (glibc 2.26), if you try
calling strlen in the inferior, you now get:

  (top-gdb) p strlen ("hello")
  '__strlen_avx2' has unknown return type; cast the call to its declared return type

This is correct, because __strlen_avx2 is written in assembly.

We can improve on this though -- if the final ifunc resolved/target
function has no debug info, but the ifunc _resolver_ does have debug
info, we can try extracting the final function's type from the type
that the resolver returns.  E.g.,:

  typedef size_t (*strlen_t) (const char*);

  size_t my_strlen (const char *) { /* some implementation */ }
  strlen_t strlen_resolver (unsigned long hwcap) { return my_strlen; }

  extern size_t strlen (const char *s);
  __typeof (strlen) strlen __attribute__ ((ifunc ("strlen_resolver")));

In the strlen example above, the resolver returns strlen_t, which is a
typedef for pointer to a function that returns size_t.  "strlen_t" is
the type of both the user-visible "strlen", and of the the target
function that implements it.

This patch teaches GDB to extract that type.

This is done for actual inferior function calls (in infcall.c), and
for ptype (in eval_call).  By the time we get to either of these
places, we've already lost the original symbol/minsym, and only have
values and types to work with.  Hence the changes to c-exp.y and
evaluate_var_msym_value, to ensure that we propagate the ifunc
minsymbol's info.

The change to make ifunc symbols have no/unknown return type exposes a
latent problem -- gdb.compile/compile-ifunc.exp calls a no-debug-info
function, but we did not warn about it.  The test is fixed by this
commit too.

ced9779b4c (Ada) fix handling of minimal symbols (UNOP_CAST and UNOP_ADDR)
Consider a program which provides a symbol without debugging
information. For instance, compiling the following code without -g:

    Some_Minimal_Symbol : Integer := 1234;
    pragma Export (C, Some_Minimal_Symbol, "some_minsym");

Trying to print this variable with GDB now causes an error, which
is now expected:

    (gdb) p some_minsym
    'some_minsym' has unknown type; cast it to its declared type

However, trying to cast this symbol, or to take its address
does not work:

    (gdb) p integer(some_minsym)
    'some_minsym' has unknown type; cast it to its declared type
    (gdb) p &some_minsym
    'some_minsym' has unknown type; cast it to its declared type

Another manisfestation of this issue can be seen when trying to
insert an Ada exception catchpoint for a specific standard exception
(this only occurs if the Ada runtime is built without debugging
information, which is the default).  For instance:

    $ (gdb) catch exception constraint_error
    warning: failed to reevaluate internal exception condition for catchpoint 0: 'constraint_error' has unknown type; cast it to its declared type

This is because, internally, the cachtpoint uses a condition referencing
a minimal symbol, more precisely:

   long_integer (e) = long_integer (&constraint_error)

This patch fixes all issues listed above:

  1. resolve_subexp: Special-case the handling of OP_VAR_MSYM_VALUE
     expression elements, where there are no ambiguities to be resolved
     in that situation;

  2. ada_evaluate_subexp: Enhance the handling of the UNOP_CAST
     handling so as to process the case where the target of
     the cast is a minimal symbol (as well as a symbol with debugging
     information). This mimics what's done in C.

edd079d9f6 Target FP: Use target format throughout expression parsing
When parsing floating-point literals, the language parsers currently
use parse_float or some equivalent routine to parse the input string
into a DOUBLEST, which is then stored within a OP_DOUBLE expression
node.  When evaluating the expression, the OP_DOUBLE is finally
converted into a value in target format.

On the other hand, *decimal* floating-point literals are parsed
directly into target format and stored that way in a OP_DECFLOAT
expression node.  In order to eliminate the DOUBLEST, this patch
therefore unifies the handling of binary and decimal floating-
point literals and stores them both in target format within a
new OP_FLOAT expression node, replacing both OP_DOUBLE and
OP_DECFLOAT.

In order to store literals in target format, the parse_float
routine needs to know the type of the literal.  All parsers
therefore need to be changed to determine the appropriate type
(e.g. by detecting suffixes) *before* calling parse_float,
instead of after it as today.  However, this change is mostly
straightforward -- again, this is already done for decimal FP
today.

The core of the literal parsing is moved into a new routine
floatformat_from_string, mirroring floatformat_to_string.
The parse_float routine now calls either floatformat_from_string
or decimal_from_sting, allowing it to handle any type of FP
literal.

All language parsers need to be updated.  Some notes on
specific changes to the various languages:

- C: Decimal FP is now handled in parse_float, and no longer
  needs to be handled specially.

- D: Straightforward.

- Fortran: Still used a hard-coded "atof", also replaced by
  parse_float now.  Continues to always use builtin_real_s8
  as the type of literal, even though this is probably wrong.

- Go: This used to handle "f" and "l" suffixes, even though
  the Go language actually doesn't support those.  I kept this
  support for now -- maybe revisit later.  Note the the GDB
  test suite for some reason actually *verifies* that GDB supports
  those unsupported suffixes ...

- Pascal: Likewise -- this handles suffixes that are not
  supported in the language standard.

- Modula-2: Like Fortran, used to use "atof".

- Rust: Mostly straightforward, except for a unit-testing hitch.
  The code use to set a special "unit_testing" flag which would
  cause "rust_type" to always return NULL.  This makes it not
  possible to encode a literal into target format (which type?).
  The reason for this flag appears to have been that during
  unit testing, there is no "rust_parser" context set up, which
  means no "gdbarch" is available to use its types.  To fix this,
  I removed the unit_testing flag, and instead simply just set up
  a dummy rust_parser context during unit testing.

- Ada: This used to check sizeof (DOUBLEST) to determine which
  type to use for floating-point literal.  This seems questionable
  to begin with (since DOUBLEST is quite unrelated to target formats),
  and in any case we need to get rid of DOUBLEST.  I'm now simply
  always using the largest type (builtin_long_double).

c83833f493 eval.c:evaluate_subexp_standard: Use RAII to avoid leaks
While working on the no-debug-info debugging improvements series, I
noticed these bare xfree calls, which lead to leaks if
evaluate_subexp_standard throws.

Fix that by reworking make_params as a RAII class.  Ends up
eliminating a couple heap allocations too.

While working on the no-debug-info debugging improvements, I found
evaluate_subexp_standard's function call code unnecessarily long and

This commit tries to improve things by factoring out the

3693fdb3c8 Make "p S::method() const::static_var" work too
Trying to print a function local static variable of a const-qualified
method still doesn't work after the previous fixes:

  (gdb) p 'S::method() const'::static_var
  $1 = {i1 = 1, i2 = 2, i3 = 3}
  (gdb) p S::method() const::static_var
  No symbol "static_var" in specified context.

The reason is that the expression parser/evaluator loses the "const",
and the above unquoted case is just like trying to print a variable of
the non-const overload, if it exists, even.  As if the above unquoted
case had been written as:

  (gdb) p S::method()::static_var
  No symbol "static_var" in specified context.

We can see the problem without static vars in the picture.  With:

 struct S
 {
    void method ();
    void method () const;
 };

Compare:

  (gdb) print 'S::method(void) const'
  $1 = {void (const S * const)} 0x400606 <S::method() const>
  (gdb) print S::method(void) const
  $2 = {void (S * const)} 0x4005d8 <S::method()>   # wrong method!

That's what we need to fix.  If we fix that, the function local static
case starts working.

The grammar production for function/method types is this one:

  exp:       exp '(' parameter_typelist ')' const_or_volatile

This results in a TYPE_INSTANCE expression evaluator operator.  For
the example above, we get something like this ("set debug expression 1"):

...
            0  TYPE_INSTANCE         1 TypeInstance: Type @0x560fda958be0 (void)
            5    OP_SCOPE              Type @0x560fdaa544d8 (S) Field name: `method'
...

While evaluating TYPE_INSTANCE, we end up in
value_struct_elt_for_reference, trying to find the method named
"method" that has the prototype recorded in TYPE_INSTANCE.  In this
case, TYPE_INSTANCE says that we're looking for a method that has
"(void)" as parameters (that's what "1 TypeInstance: Type
@0x560fda958be0 (void)" above means.  The trouble is that nowhere in
this mechanism do we communicate to value_struct_elt_for_reference
that we're looking for the _const_ overload.
value_struct_elt_for_reference only compared parameters, and the
non-const "method()" overload has matching parameters, so it's
considered the right match...

Conveniently, the "const_or_volatile" production in the grammar
already records "const" and "volatile" info in the type stack.  The
type stack is not used in this code path, but we can borrow the
information.  The patch converts the info in the type stack to an
"instance flags" enum, and adds that as another element in
TYPE_INSTANCE operators.  This type instance flags is then applied to
the temporary type that is passed to value_struct_elt_for_reference
for matching.

The other side of the problem is that methods in the debug info aren't
marked const/volatile, so with that in place, the matching never finds
const/volatile-qualified methods.

The problem is that in the DWARF, there's no indication at all whether
a method is const/volatile qualified...  For example (c++filt applied
to the linkage name for convenience):

   <2><d3>: Abbrev Number: 6 (DW_TAG_subprogram)
      <d4>   DW_AT_external    : 1
      <d4>   DW_AT_name        : (indirect string, offset: 0x3df): method
      <d8>   DW_AT_decl_file   : 1
      <d9>   DW_AT_decl_line   : 58
      <da>   DW_AT_linkage_name: (indirect string, offset: 0x5b2): S::method() const
      <de>   DW_AT_declaration : 1
      <de>   DW_AT_object_pointer: <0xe6>
      <e2>   DW_AT_sibling     : <0xec>

I see the same with both GCC and Clang.  The patch works around this
by extracting the cv qualification from the "const" and "volatile" in
the demangled name.  This will need further tweaking for "&" and
"const &" overloads, but we don't support them in the parser yet,
anyway.

The TYPE_CONST changes were necessary otherwise the comparisons in valops.c:

  if (TYPE_CONST (intype) != TYPE_FN_FIELD_CONST (f, j))
    continue;

would fail, because when both TYPE_CONST() TYPE_FN_FIELD_CONST() were
true, their values were different.

BTW, I'm recording the const/volatile-ness of methods in the
TYPE_FN_FIELD info because #1 - I'm not sure it's kosher to change the
method's type directly (vs having to call make_cv_type to create a new
type), and #2 it's what stabsread.c does:

...
	    case 'A':		/* Normal functions.  */
	      new_sublist->fn_field.is_const = 0;
	      new_sublist->fn_field.is_volatile = 0;
	      (*pp)++;
	      break;
	    case 'B':		/* `const' member functions.  */
	      new_sublist->fn_field.is_const = 1;
	      new_sublist->fn_field.is_volatile = 0;
...

After all this, this finally all works:

  print S::method(void) const
  $1 = {void (const S * const)} 0x400606 <S::method() const>
  (gdb) p S::method() const::static_var
  $2 = {i1 = 1, i2 = 2, i3 = 3}

858be34c5a Handle "p S::method()::static_var" in the C++ parser
This commit makes "print S::method()::static_var" actually find the
debug symbol for static_var.  Currently, you get:

  (gdb) print S::method()::static_var
  A syntax error in expression, near `'.

Quoting the whole string would seemingly work before the previous
patch that made GDB stop assuming int for no-debug-info variables:

  (gdb) p 'S::method()::static_var'
  $1 = 1

... except that's incorrect output, because:

  (gdb) ptype 'S::method()::static_var'
  type = <data variable, no debug info>

The way to make it work correctly currently is by quoting the
function/method part, like this:

  (gdb) print 'S::method()'::static_var
  $1 = {i1 = 1, i2 = 2, i3 = 3}
  (gdb) ptype 'S::method()'::static_var
  type = struct aggregate {
      int i1;
      int i2;
      int i3;
  }

At least after the "stop assuming int" patch, this is what we
now get:

  (gdb) p 'S::method()::static_var'
  'S::method()::static_var' has unknown type; cast it to its declared type
  (gdb) p (struct aggregate) 'S::method()::static_var'
  $1 = {i1 = 1, i2 = 2, i3 = 3}

However, IMO, users shouldn't really have to care about any of this.
GDB should Just Work, without quoting, IMO.

So here's a patch that implements support for that in the C++ parser.
With this patch, you now get:

  (gdb) p S::method()::S_M_s_var_aggregate
  $1 = {i1 = 1, i2 = 2, i3 = 3}
  (gdb) ptype S::method()::S_M_s_var_aggregate
  type = struct aggregate {
      int i1;
      int i2;
      int i3;
  }

46a4882b3c Stop assuming no-debug-info variables have type int
An earlier commit made GDB no longer assume no-debug-info functions
return int.  This commit gives the same treatment to variables.

Currently, you can end misled by GDB over output like this:

  (gdb) p var
  $1 = -1
  (gdb) p /x var
  $2 = 0xffffffff

until you realize that GDB is assuming that the variable is an "int",
because:

  (gdb) ptype var
  type = <data variable, no debug info>

You may try to fix it by casting, but that doesn't really help:

  (gdb) p /x (unsigned long long) var
  $3 = 0xffffffffffffffff            # incorrect
         ^^

That's incorrect output, because the variable was defined like this:

  uint64_t var = 0x7fffffffffffffff;
                   ^^

What happened is that with the cast, GDB did an int -> 'unsigned long
long' conversion instead of reinterpreting the variable as the cast-to
type.  To get at the variable properly you have to reinterpret the
variable's address manually instead, with either:

  (gdb) p /x *(unsigned long long *) &var
  $4 = 0x7fffffffffffffff
  (gdb) p /x {unsigned long long} &var
  $5 = 0x7fffffffffffffff

After this commit GDB does it for you.  This is what you'll get
instead:

  (gdb) p var
  'var' has unknown type; cast it to its declared type
  (gdb) p /x (unsigned long long) var
  $1 = 0x7fffffffffffffff

As in the functions patch, the "compile" machinery doesn't currently
have the cast-to type handy, so it continues assuming no-debug
variables have int type, though now at least it warns.

The change to gdb.cp/m-static.exp deserves an explanation:

 - gdb_test "print 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \
 + gdb_test "print (int) 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \

That's printing the "sintvar" function local static of the
"gnu_obj_1::method()" method.

The problem with that test is that that "'S::method()::static_var'"
syntax doesn't really work in C++ as you'd expect.  The way to make it
work correctly currently is to quote the method part, not the whole
expression, like:

  (gdb) print 'gnu_obj_1::method()'::sintvar

If you wrap the whole expression in quotes, like in m-static.exp, what
really happens is that the parser considers the whole string as a
symbol name, but there's no debug symbol with that name.  However,
local statics have linkage and are given a mangled name that demangles
to the same string as the full expression, so that's what GDB prints.
After this commit, and without the cast, the print in m-static.exp
would error out saying that the variable has unknown type:

  (gdb) p 'gnu_obj_1::method()::sintvar'
  'gnu_obj_1::method()::sintvar' has unknown type; cast it to its declared type

TBC, if currently (even before this series) you try to print any
function local static variable of type other than int, you'll get
bogus results.  You can see that with m-static.cc as is, even.
Printing the "svar" local, which is a boolean (1 byte) still prints as
"int" (4 bytes):

  (gdb) p 'gnu_obj_1::method()::svar'
  $1 = 1
  (gdb) ptype 'gnu_obj_1::method()::svar'
  type = <data variable, no debug info>

This probably prints some random bogus value on big endian machines.

If 'svar' was of some aggregate type (etc.) we'd still print it as
int, so the problem would have been more obvious...  After this
commit, you'll get instead:

  (gdb) p 'gnu_obj_1::method()::svar'
  'gnu_obj_1::method()::svar' has unknown type; cast it to its declared type

... so at least GDB is no longer misleading.  Making GDB find the real
local static debug symbol is the subject of the following patches.  In
the end, it'll all "Just Work".

2c5a2be190 Make ptype/whatis print function name of functions with no debug info too
The patch to make GDB stop assuming functions return int left GDB with
an inconsistency.  While with normal expression evaluation the
"unknown return type" error shows the name of the function that misses
debug info:

  (gdb) p getenv ("PATH")
  'getenv' has unknown return type; cast the call to its declared return type
   ^^^^^^

which is handy in more complicated expressions, "ptype" does not:

  (gdb) ptype getenv ("PATH")
  function has unknown return type; cast the call to its declared return type
  ^^^^^^^^

This commit builds on the new OP_VAR_MSYM_VALUE to fix it, by making
OP_FUNCALL extract the function name from the symbol stored in
OP_VAR_VALUE/OP_VAR_MSYM_VALUE.  We now get the same error in "print"
vs "ptype":

74ea4be48e Introduce OP_VAR_MSYM_VALUE
The previous patch left GDB with an inconsistency.  While with normal
expression evaluation the "unknown return type" error shows the name
of the function that misses debug info:

  (gdb) p getenv ("PATH")
  'getenv' has unknown return type; cast the call to its declared return type
   ^^^^^^

which can by handy in more complicated expressions, "ptype" does not:

  (gdb) ptype getenv ("PATH")
  function has unknown return type; cast the call to its declared return type
  ^^^^^^^^

This commit is a step toward fixing it.

The problem is that while evaluating the expression above, we have no
reference to the minimal symbol where we could extract the name from.
This is because the resulting expression tree has no reference to the
minsym at all.  During parsing, the type and address of the minsym are
extracted and an UNOP_MEMVAL / UNOP_MEMVAL_TLS operator is generated
(see write_exp_elt_msym).  With "set debug expression", here's what
you see:

            0  OP_FUNCALL            Number of args: 0
            3    UNOP_MEMVAL           Type @0x565334a51930 (<text variable, no debug info>)
            6      OP_LONG               Type @0x565334a51c60 (__CORE_ADDR), value 140737345035648 (0x7ffff7751d80)

The "print" case finds the function name, because
call_function_by_hand looks up the function by address again.
However, for "ptype", we don't reach that code, because obviously we
don't really call the function.

Unlike minsym references, references to variables with debug info have
a pointer to the variable's symbol in the expression tree, with
OP_VAR_VALUE:

  (gdb) ptype main()
  ...
            0  OP_FUNCALL            Number of args: 0
            3    OP_VAR_VALUE          Block @0x0, symbol @0x559bbbd9b358 (main(int, char**))
  ...

so I don't see why do minsyms need to be different.  So to prepare for
fixing the missing function name issue, this commit adds a new
OP_VAR_MSYM_VALUE operator that mimics OP_VAR_VALUE, except that it's
for minsyms instead of debug symbols.  For infcalls, we now get
expressions like these:

            0  OP_FUNCALL            Number of args: 0
            3    OP_VAR_MSYM_VALUE     Objfile @0x1e41bf0, msymbol @0x7fffe599b000 (getenv)

In the following patch, we'll make OP_FUNCALL extract the function
name from the symbol stored in OP_VAR_VALUE/OP_VAR_MSYM_VALUE.

OP_VAR_MSYM_VALUE will be used more in a later patch in the series
too.

7022349d5c Stop assuming no-debug-info functions return int
The fact that GDB defaults to assuming that functions return int, when
it has no debug info for the function has been a recurring source of
user confusion.  Recently this came up on the errno pretty printer
discussions.  Shortly after, it came up again on IRC, with someone
wondering why does getenv() in GDB return a negative int:

  (gdb) p getenv("PATH")
  $1 = -6185

This question (with s/getenv/random-other-C-runtime-function) is a FAQ
on IRC.

The reason for the above is:

 (gdb) p getenv
 $2 = {<text variable, no debug info>} 0x7ffff7751d80 <getenv>
 (gdb) ptype getenv
 type = int ()

... which means that GDB truncated the 64-bit pointer that is actually
returned from getent to 32-bit, and then sign-extended it:

 (gdb) p /x -6185
 $6 = 0xffffe7d7

The workaround is to cast the function to the right type, like:

 (gdb) p ((char *(*) (const char *)) getenv) ("PATH")
 $3 = 0x7fffffffe7d7 "/usr/local/bin:/"...

IMO, we should do better than this.

I see the "assume-int" issue the same way I see printing bogus values
for optimized-out variables instead of "<optimized out>" -- I'd much
rather that the debugger tells me "I don't know" and tells me how to
fix it than showing me bogus misleading results, making me go around
tilting at windmills.

If GDB prints a signed integer when you're expecting a pointer or
aggregate, you at least have some sense that something is off, but
consider the case of the function actually returning a 64-bit integer.
For example, compile this without debug info:

 unsigned long long
 function ()
 {
   return 0x7fffffffffffffff;
 }

Currently, with pristine GDB, you get:

 (gdb) p function ()
 $1 = -1                      # incorrect
 (gdb) p /x function ()
 $2 = 0xffffffff              # incorrect

maybe after spending a few hours debugging you suspect something is
wrong with that -1, and do:

 (gdb) ptype function
 type = int ()

and maybe, just maybe, you realize that the function actually returns
unsigned long long.  And you try to fix it with:

(gdb) p /x (unsigned long long) function ()
 $3 = 0xffffffffffffffff      # incorrect

... which still produces the wrong result, because GDB simply applied
int to unsigned long long conversion.  Meaning, it sign-extended the
integer that it extracted from the return of the function, to 64-bits.

and then maybe, after asking around on IRC, you realize you have to
cast the function to a pointer of the right type, and call that.  It
won't be easy, but after a few missteps, you'll get to it:

.....  (gdb) p /x ((unsigned long long(*) ()) function) ()
 $666 = 0x7fffffffffffffff             # finally! :-)


So to improve on the user experience, this patch does the following
(interrelated) things:

 - makes no-debug-info functions no longer default to "int" as return
   type.  Instead, they're left with NULL/"<unknown return type>"
   return type.

    (gdb) ptype getenv
    type = <unknown return type> ()

 - makes calling a function with unknown return type an error.

    (gdb) p getenv ("PATH")
    'getenv' has unknown return type; cast the call to its declared return type

 - and then to make it easier to call the function, makes it possible
   to _only_ cast the return of the function to the right type,
   instead of having to cast the function to a function pointer:

    (gdb) p (char *) getenv ("PATH")                      # now Just Works
    $3 = 0x7fffffffe7d7 "/usr/local/bin:/"...

    (gdb) p ((char *(*) (const char *)) getenv) ("PATH")  # continues working
    $4 = 0x7fffffffe7d7 "/usr/local/bin:/"...

   I.e., it makes GDB default the function's return type to the type
   of the cast, and the function's parameters to the type of the
   arguments passed down.

After this patch, here's what you'll get for the "unsigned long long"
example above:

 (gdb) p function ()
 'function' has unknown return type; cast the call to its declared return type
 (gdb) p /x (unsigned long long) function ()
 $4 = 0x7fffffffffffffff     # correct!

Note that while with "print" GDB shows the name of the function that
has the problem:

  (gdb) p getenv ("PATH")
  'getenv' has unknown return type; cast the call to its declared return type

which can by handy in more complicated expressions, "ptype" does not:

  (gdb) ptype getenv ("PATH")
  function has unknown return type; cast the call to its declared return type

This will be fixed in the next patch.

c973d0aa4a Fix type casts losing typedefs and reimplement "whatis" typedef stripping
(Ref: https://sourceware.org/ml/gdb/2017-06/msg00020.html)

Assuming int_t is a typedef to int:

 typedef int int_t;

gdb currently loses this expression's typedef:

 (gdb) p (int_t) 0
 $1 = 0
 (gdb) whatis $1
 type = int

or:

 (gdb) whatis (int_t) 0
 type = int

or, to get "whatis" out of the way:

 (gdb) maint print type (int_t) 0
 ...
 name 'int'
 code 0x8 (TYPE_CODE_INT)
 ...

This prevents a type printer for "int_t" kicking in, with e.g.:

 (gdb) p (int_t) 0

From the manual, we can see that that "whatis (int_t) 0" command
invocation should have printed "type = int_t":

 If @var{arg} is a variable or an expression, @code{whatis} prints its
 literal type as it is used in the source code.  If the type was
 defined using a @code{typedef}, @code{whatis} will @emph{not} print
 the data type underlying the @code{typedef}.
 (...)
 If @var{arg} is a type name that was defined using @code{typedef},
 @code{whatis} @dfn{unrolls} only one level of that @code{typedef}.

That one-level stripping is currently done here, in
gdb/eval.c:evaluate_subexp_standard, handling OP_TYPE:

...
     else if (noside == EVAL_AVOID_SIDE_EFFECTS)
	{
	  struct type *type = exp->elts[pc + 1].type;

	  /* If this is a typedef, then find its immediate target.  We
	     use check_typedef to resolve stubs, but we ignore its
	     result because we do not want to dig past all
	     typedefs.  */
	  check_typedef (type);
	  if (TYPE_CODE (type) == TYPE_CODE_TYPEDEF)
	    type = TYPE_TARGET_TYPE (type);
	  return allocate_value (type);
	}

However, this stripping is reachable in both:

 #1 - (gdb) whatis (int_t)0     # ARG is an expression with a cast to
                                # typedef type.
 #2 - (gdb) whatis int_t        # ARG is a type name.

while only case #2 should strip the typedef.  Removing that code from
evaluate_subexp_standard is part of the fix.  Instead, we make the
"whatis" command implementation itself strip one level of typedefs
when the command argument is a type name.

We then run into another problem, also fixed by this commit:
value_cast always drops any typedefs of the destination type.

With all that fixed, "whatis (int_t) 0" now works as expected:

 (gdb) whatis int_t
 type = int
 (gdb) whatis (int_t)0
 type = int_t

value_cast has many different exit/convertion paths, for handling many
different kinds of casts/conversions, and most of them had to be
tweaked to construct the value of the right "to" type.  The new tests
try to exercise most of it, by trying castin of many different
combinations of types.  With:

 $ make check TESTS="*/whatis-ptype*.exp */gnu_vector.exp */dfp-test.exp"

... due to combinatorial explosion, the testsuite results for the
tests above alone grow like:

 - # of expected passes            246
 + # of expected passes            3811

You'll note that the tests exposed one GCC buglet, filed here:

aa0061181a Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

4d01a485d2 'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:

  typedef gdb::unique_malloc_ptr<expression> expression_up;

and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.

Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.

[1] - I'd like to set the rule that types named with an "_up" suffix
      are unique_ptr typedefs.

Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects.  Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

6b8505468e Support structure offsets that are 512K or larger.
GDB computes structure byte offsets using a 32 bit integer.  And,
first it computes the offset in bits and then converts to bytes.  The
result is that any offset that if 512K bytes or larger overflows.
This patch changes GDB to use LONGEST for such calculations.

ac775bf4d3 gdb: Forward VALUE_LVAL when avoiding side effects for STRUCTOP_PTR
Assume that we have a C program like this:

  struct foo_type
  {
    int var;
  } foo;

  struct foo_type *foo_ptr = &foo;

  int
  main ()
  {
    return foo_ptr->var;
  }

Then GDB should be able to evaluate the following, however, it currently
does not:

  (gdb) start
  ...
  (gdb) whatis &(foo_ptr->var)
  Attempt to take address of value not located in memory.

The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_PTR operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned
value.

This patch fixes STRUCTOP_PTR handling so that the VALUE_LVAL
attribute for the returned value is properly initialized.  After this
change, the above session becomes:

  (gdb) start
  ...
  (gdb) whatis &(foo_ptr->var)
  type = int *

This commit is largely the same as commit 2520f728b7 (Forward
VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT) but applied
to STRUCTOP_PTR rather than STRUCTOP_STRUCT.  Both of these commits are
building on top of commit ac1ca910d7 (Fixes for PR exp/15364).

gdb/ChangeLog:

	* eval.c (evaluate_subexp_standard): If EVAL_AVOID_SIDE_EFFECTS
	mode, forward the VALUE_LVAL attribute to the returned value in
	the STRUCTOP_PTR case.

gdb/testsuite/ChangeLog:

	* gdb.base/whatis.c: Extend the test case.
	* gdb.base/whatis.exp: Add additional tests.

cc63428a4c gdb: allow enumeration constants as second operand of BINOP_REPEAT
This patch adds support for TYPE_CODE_ENUM values to be supplied
as right-hand side operand of the BINOP_REPEAT (@) operator. The
following should now work:

enum {
  sz = 17
};

int
main ()
{
  int arr[sz + 1] = { 0 };
  return 0; /* line 9 here */
}

(gdb) b 9
(gdb) r
(gdb) p arr@sz
$1 = {0 <repeats 17 times>}
(gdb)

A couple of tests is also included in this patch to demonstrate that it is
working as intended.

2520f728b7 Forward VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT
Assume foo_array is a pointer to a C structure. GDB must evaluate the
following expression properly, but it does not currently:

    (gdb) print 1 && &foo_array[1].a
    Attempt to take address of value not located in memory.

The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_STRUCT operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned
value.

This patch fixes STRUCTOP_STRUCT handling so that the VALUE_LVAL
attribute for the returned value is properly initialized.  After this
change, the above session becomes:

    (gdb) print 1 && &foo_array[1].a
    $1 = 1

8d7493201c Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort.  The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family.  This avoids adding an explicit cast, so
it keeps the code a bit more readable.  Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.

I only changed calls that were obviously allocating memory for one or
multiple "objects".  Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).

  - xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
  - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
  - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
  - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
  - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
  - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
  - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
  - alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
  - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)

Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.

I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files.  For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

aead7601eb Add casts for legitimate integer to enum conversions
This patch is mostly extracted from Pedro's C++ branch.  It adds explicit
casts from integer to enum types, where it is really the intention to do
so.  This could be because we are ...

 * iterating on enum values (we need to iterate on an equivalent integer)
 * converting from a value read from bytes (dwarf attribute, agent
 expression opcode) to the equivalent enum
 * reading the equivalent integer value from another language (Python/Guile)

An exception to that is the casts in regcache.c.  It seems to me like
struct regcache's register_status field could be a pointer to an array of
enum register_status.  Doing so would waste a bit of memory (4 bytes
used by the enum vs 1 byte used by the current signed char, for each
register).  If we switch to C++11 one day, we can define the underlying
type of an enum type, so we could have the best of both worlds.

d12307c199 Replace the block_found global with explicit data-flow
As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found.  This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.

f486487f55 Mostly trivial enum fixes
This is a patch I extracted from Pedro's C++ branch.  It contains the
most trivial enum fixes, where an integer type/value was used instead
of the appropriate enum type/value.  It fixes many C++ errors, since
in C++ you can't mix integers and enums implicitely.

Regardless of the C++ conversion, I think this is a good cleanup to make
use of the appropriate enum types.

Regression-tested on native x86_64.

f168693bc9 Remove CHECK_TYPEDEF, use check_typedef instead
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying.  It makes unclear the fact that the "type" variables gets
overwritten.  It has actually bitten me a few times.  I think the
following, explicit form, is better.

  type = check_typedef (type);

This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef.  The bulk of the change was done with this sed:

  sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c

The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.

The patch was built-tested, and I ran a few smoke tests.

492d29ea1c Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from
this:

~~~
  volatile gdb_exception ex;

  TRY_CATCH (ex, RETURN_MASK_ERROR)
    {
    }
  if (ex.reason < 0)
    {
    }
~~~

to this:

~~~
  TRY
    {
    }
  CATCH (ex, RETURN_MASK_ERROR)
    {
    }
  END_CATCH
~~~

Thus, we'll be getting rid of the local volatile exception object, and
declaring the caught exception in the catch block.

This allows reimplementing TRY/CATCH in terms of C++ exceptions when
building in C++ mode, while still allowing to build GDB in C mode
(using setjmp/longjmp), as a transition step.

TBC, after this patch, is it _not_ valid to have code between the TRY
and the CATCH blocks, like:

  TRY
    {
    }

  // some code here.

  CATCH (ex, RETURN_MASK_ERROR)
    {
    }
  END_CATCH

Just like it isn't valid to do that with C++'s native try/catch.

By switching to creating the exception object inside the CATCH block
scope, we can get rid of all the explicitly allocated volatile
exception objects all over the tree, and map the CATCH block more
directly to C++'s catch blocks.

The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was
done with a script, rerun from scratch at every rebase, no manual
editing involved.  After the mechanical conversion, a few places
needed manual intervention, to fix preexisting cases where we were
using the exception object outside of the TRY_CATCH block, and cases
where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH
after this patch].  The result was folded into this patch so that GDB
still builds at each incremental step.

END_CATCH is necessary for two reasons:

First, because we name the exception object in the CATCH block, which
requires creating a scope, which in turn must be closed somewhere.
Declaring the exception variable in the initializer field of a for
block, like:

  #define CATCH(EXCEPTION, mask) \
    for (struct gdb_exception EXCEPTION; \
         exceptions_state_mc_catch (&EXCEPTION, MASK); \
	 EXCEPTION = exception_none)

would avoid needing END_CATCH, but alas, in C mode, we build with C90,
which doesn't allow mixed declarations and code.

Second, because when TRY/CATCH are wired to real C++ try/catch, as
long as we need to handle cleanup chains, even if there's no CATCH
block that wants to catch the exception, we need for stop at every
frame in the unwind chain and run cleanups, then rethrow.  That will
be done in END_CATCH.

After we require C++, we'll still need TRY/CATCH/END_CATCH until
cleanups are completely phased out -- TRY/CATCH in C++ mode will
save/restore the current cleanup chain, like in C mode, and END_CATCH
catches otherwise uncaugh exceptions, runs cleanups and rethrows, so
that C++ cleanups and exceptions can coexist.

IMO, this still makes the TRY/CATCH code look a bit more like a
newcomer would expect, so IMO worth it even if we weren't considering
C++.

b1f28d992c Work around GCC bug 63748
A recent change to eval.c triggered a GCC bug that causes a false positive
"may be used uninitialized" warning in evaluate_subexp_standard.  This seems
to be triggered by a specific CFG constructed via setjmp and gotos.

While the GCC bug is in the process of being fixed, there are released
compiler versions (in particular GCC 4.9) in the field that show this
problem.  In order to allow compiling GDB with one of those compilers,
this commit slightly reworks the CFG (in an equivalent way) of the
affected function, so that the GCC bug is no longer triggered.

e66d444669 Add new argument NOSIDE to find_overload_match.
This is a fix for PR c++/17132.
If this new argument is set to EVAL_AVOID_SIDE_EFFECTS, then the object's
memory will not be read while picking the best overload match.

The c99 standard in "6.5.3.4 The sizeof operator" states:

This patch mirrors the following c99 semantic in gdb:

 4| assert (i == 1);

Note: ptype/whatis still do not allow any sideeffects.

In C99 the sizeof operator computes the size of a variable length array
at runtime (6.5.3.4 The sizeof operator). This patch reflects the semantic
change in the debugger.

We now are able to get the size of a vla:

1| void foo (size_t n) {
2|   int vla[n];
3| }

(gdb) p sizeof(vla)

yields N * sizeof(int).

gdb/ChangeLog:

	passed to sizeof is dynamic evaluate the argument to compute the length.

3b7344d5ab use bound_minsym as result for lookup_minimal_symbol et al
This patch changes a few minimal symbol lookup functions to return a
bound_minimal_symbol rather than a pointer to the minsym.  This change
helps prepare gdb for computing a minimal symbol's address at the
point of use.

Note that this changes even those functions that ostensibly search a
single objfile.  That was necessary because, in fact, those functions
can search an objfile and its separate debug objfiles; and it is
important for the caller to know in which objfile the minimal symbol
was actually found.

The bulk of this patch is mechanical.

3a1115a0cc fix PR symtab/15719
This patch fixes PR symtab/15719.

The bug is that "watch -location" crashes on a certain expression.

The problem is that fetch_subexp_value is catching an exception.
For ordinary watchpoints this is ok; but for location watchpoints,
it is better for the exception to propagate.

Built and regtested on x86-64 Fedora 18.
New test case included.

4819b3f897 Fix ptype bug actually exercised in userdef.exp
I happened to notice a bug with ptype &Ref, and found out userdef.exp
actually exercises the bug.  With:

class Container
{
public:
  Member m;

  Member& operator* ();
};

Member& Container::operator* ()
{
  return this->m;
}

And 'c' is of type Container:

(gdb) p c
$1 = {m = {z = -9192}}
(gdb) p *c
$2 = (Member &) @0x7fffffffda20: {z = -9192}
(gdb) ptype *c
type = class Member {
  public:
    int z;
} &

(gdb) p &*c
$3 = (Member *) 0x7fffffffda20

(gdb) ptype &*c
type = class Member {
  public:
    int z;
} &*
(gdb)

Notice that last print (&*c) on says the type is a pointer - that's
how you get the address behind a reference.  But notice the last ptype
instead says the type of the same expression is a pointer _reference_.
This looks like a bug to me.

This patch fixes it.  The issue is that we're entering the VALUE_LVAL
(x) == lval_memory branch by mistake for references.  The fix is just
to swap the tests so references are checked first, like value_addr
also handles references first.

Tested on x86_64 Fedora 17.
