1a5c25988e Normalize include guards in gdb
While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards.  I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.

So, I changed the script to normalize all include guards in gdb.  This
patch is the result.

As usual the script is available here:

    https://github.com/tromey/gdb-refactoring-scripts

Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

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.

e71585ffe2 Use gdb:array_view in call_function_by_hand & friends
This replaces a few uses of pointer+length with gdb::array_view, in
call_function_by_hand and related code.

Unfortunately, due to -Wnarrowing, there are places where we can't
brace-initialize an gdb::array_view without an ugly-ish cast.  To
avoid the cast, this patch introduces a gdb::make_array_view function.
Unit tests included.

This patch in isolation may not look so interesting, due to
gdb::make_array_view uses, but I think it's still worth it.  Some of
the gdb::make_array_view calls disappear down the series, and others
could be eliminated with more (non-trivial) gdb::array_view
detangling/conversion (e.g. code around eval_call).  See this as a "we
have to start somewhere" patch.

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.

8588b35692 python: Make gdb.execute("show commands") work (PR 23669)
Since commit

  56bcdbea2b ("Let gdb.execute handle multi-line commands")

trying to use a command like gdb.execute("show commands") in Python
fails.  GDB ends up trying to run the "commands" command.

The reason is that GDB gets confused with the special "commands"
command.  In process_next_line, the lookup_cmd_1 function returns the
cmd_list_element representing the "commands" sub-command of "show".
Lower, we check the cmd_list_element to see if it matches various
control commands by name, including the "commands" command.  This is
where we wrongfully conclude that the executed command must be
"commands", when in reality it was "show commands".

The fix proposed in this patch removes the comparisons by name, instead
comparing the cmd_list_element object by pointer with the objects
created at initialization time.

Tested on the buildbot, though on a single builder (Fedora-x86_64-m64).

	PR python/23669
	* breakpoint.c (commands_cmd_element): New.

4895f384b4 Don't throw Scheme exceptions with live std::vector objects
A complication with the Guile code is that we have two types of
exceptions to consider: GDB/C++ exceptions, and Guile/SJLJ exceptions.

Because Guile exceptions are SJLJ based, we must make sure to not have
live local variables of types with non-trivial dtors when a Guile
exception is thrown, because the dtors won't be run when a Guile
exceptions is thrown.

gdbscm_parse_function_args currently violates this:

 void
 gdbscm_parse_function_args (const char *func_name,
			     int beginning_arg_pos,
			     const SCM *keywords,
			     const char *format, ...)
 {
 ...
   /* Keep track of malloc'd strings.  We need to free them upon error.  */
   std::vector<char *> allocated_strings;
 ...
   for (char *ptr : allocated_strings)
     xfree (ptr);
   gdbscm_throw (status); /// dtor of "allocated_strings" is not run!
 }

This commit fixes the above making using of gdbscm_wrap.

It would be nice if we had a way to make it impossible to write such
code.  PR guile/23429 has an idea for that, if someone's interested.

This patch fixes various unused variable warnings that are related to
conditional compilation.  In these cases, either the variable is now
protected by the same #if as its uses, or the declaration is simply
lowered into the conditionally-compiled block.

4c6933327e Eliminate remaining gdb/guile cleanups
The remaining gdb/guile cleanups all handle the memory returned by
gdbscm_scm_to_c_string.

gdb::unique_xmalloc_ptr instead of a naked pointer, and eliminates the
remaining cleanups.

557e56be26 Eliminate most remaining cleanups under gdb/guile/
The main complication with the Guile code is that we have two types of
exceptions to consider.  GDB/C++ exceptions, and Guile/SJLJ
exceptions.  Code that is facing the Guile interpreter must not throw
GDB exceptions, instead Scheme exceptions must be thrown.  Also,
because Guile exceptions are SJLJ based, Guile-facing code must not
use local objects with dtors, unless wrapped in a scope with a
TRY/CATCH, because the dtors won't otherwise be run when a Guile
exceptions is thrown.

This commit adds a new gdbscm_wrap wrapper function than encapsulates
a pattern I noticed in many of the functions using
GDBSCM_HANDLE_GDB_EXCEPTION_WITH_CLEANUPS.  The wrapper is written
such that you can pass either a lambda to it, or a function plus a
variable number of forwarded args.  I used a lambda when its body
would be reasonably short, and a separate function in the larger
cases.

This also convers a few functions that were using
GDBSCM_HANDLE_GDB_EXCEPTION to use gdbscm_wrap too because they
followed a similar pattern.

A few cases of make_cleanup calls are replaced with explicit xfree
calls.  The make_cleanup/do_cleanups calls in those cases are
pointless, because do_cleanups won't be called when a Scheme exception
is thrown.

We also have a couple cases of Guile-facing code using RAII-type
objects to manage memory, but those are incorrect, exactly because
their dtor won't be called if a Guile exception is thrown.

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.

This removes a VEC from type.c, by using std::vector.

While doing this I also took the opportunity to change
types_deeply_equal to return bool.  This caught some weird code in
typy_richcompare, now fixed.

And, since I was changing types_deeply_equal, it seemed like a good
idea to also change types_equal, so this patch includes that as well.

12973681f5 Use counted_command_line everywhere
Currently command lines are reference counted using shared_ptr only
when attached to breakpoints.  This patch changes gdb to use
shared_ptr in commands as well.  This allows for the removal of
copy_command_lines.

Note that the change to execute_user_command explicitly makes a new
reference to the command line.  This will be used in a later patch.

This simplifies struct command_line based on the observation that a
given command can have at most two child bodies: an "if" can have both
"then" and "else" parts.  Perhaps the names I've chosen for the
replacements here are not very good -- your input requested.

a95c7daba4 Remove a cleanup from scm-frame.c
This removes a cleanup from scm-frame.c, replacing it with
unique_xmalloc_ptr and a new scope.  I believe this also fixes a
latent bug involving calling do_cleanups twice for a single cleanup.

Regression tested using the gdb.guile test suite on x86-64 Fedora 26.

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.

76727919ce Convert observers to C++
This converts observers from using a special source-generating script
to be plain C++.  This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).

Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.

Regression tested on the buildbot.

b4987c956d Create new common/pathstuff.[ch]
This commit moves the path manipulation routines found on utils.c to a
new common/pathstuff.c, and updates the Makefile.in's accordingly.
The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and
"gdb_abspath".

This will be needed because gdbserver will have to call "gdb_abspath"
on my next patch, which implements a way to expand the path of the
inferior provided by the user in order to allow specifying just the
binary name when starting gdbserver, like:

  $ gdbserver :1234 a.out

With the recent addition of the startup-with-shell feature on
gdbserver, this scenario doesn't work anymore if the user doesn't have
the current directory listed in the PATH variable.

I had to do a minor adjustment on "gdb_abspath" because we don't have
access to "tilde_expand" on gdbserver, so now the function is using
"gdb_tilde_expand" instead.  Otherwise, the code is the same.

Regression tested on the BuildBot, without regressions.

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);

a20714ff39 Make "break foo" find "A::foo", A::B::foo", etc. [C++ and wild matching]
This patch teaches GDB about setting breakpoints in all scopes
(namespaces and classes) by default.

Here's a contrived example:

  (gdb) b func<tab>
  (anonymous namespace)::A::function()            Bn::(anonymous namespace)::B::function()        function(int, int)
  (anonymous namespace)::B::function()            Bn::(anonymous namespace)::function()           gdb::(anonymous namespace)::A::function()

  (anonymous namespace)::function()               Bn::B::func()                                   gdb::(anonymous namespace)::function(int, int)
  (anonymous namespace)::function(int, int)       Bn::B::function()                               gdb::A::func()
  A::func()                                       Bn::func()                                      gdb::A::function()
  A::function()                                   Bn::function()                                  gdb::func()
  B::func()                                       Bn::function(int, int)                          gdb::function()
  B::function()                                   Bn::function(long)                              gdb::function(int, int)
  B::function() const                             func()                                          gdb::function(long)
  B::function_const() const                       function()
  (gdb) b function
  Breakpoint 1 at 0x4005ce: function. (26 locations)

  (gdb) b B::function<tab>
  (anonymous namespace)::B::function()        B::function() const                         Bn::B::function()
  (anonymous namespace)::B::function() const  B::function_const() const
  B::function()                               Bn::(anonymous namespace)::B::function()
  (gdb) b B::function
  Breakpoint 1 at 0x40072c: B::function. (6 locations)

To get back the original behavior of interpreting the function name as
a fully-qualified name, you can use the new "-qualified" (or "-q")
option/flag (added by this commit).  For example:

 (gdb) b B::function
 (anonymous namespace)::B::function()        B::function() const                         Bn::B::function()
 (anonymous namespace)::B::function() const  B::function_const() const
 B::function()                               Bn::(anonymous namespace)::B::function()

vs:

 (gdb) b -qualified B::function
 B::function()              B::function() const        B::function_const() const

I've chosen "-qualified" / "-q" because "-f" (for "full" or
"fully-qualified") is already taken for "-function".

Note: the "-qualified" option works with both linespecs and explicit
locations.  I.e., these are equivalent:

 (gdb) b -q func
 (gdb) b -q -f func

and so are these:

 (gdb) b -q filename.cc:func
 (gdb) b -q -s filename.cc -f func
 (gdb) b -s filename.cc -q -f func
 (gdb) b -s filename.cc -f func -q

To better understand why I consider wild matching the better default,
consider what happens when we get to the point when _all_ of GDB is
wrapped under "namespace gdb {}".  I have a patch series that does
that, and when I started debugging that GDB, I immediately became
frustrated.  You'd have to write "b gdb::internal_error", "b
gdb::foo", "b gdb::bar", etc. etc., which gets annoying pretty
quickly.  OTOH, consider how this makes it very easy to set
breakpoints in classes wrapped in anonymous namespaces.  You just
don't think of them, GDB finds the symbols for you automatically.

(At the Cauldron a couple months ago, several people told me that they
run into a similar issue when debugging other C++ projects.  One
example was when debugging LLVM, which puts all its code under the
"llvm" namespace.)

Implementation-wise, what the patch does is:

  - makes C++ symbol name hashing only consider the last component of
    a symbol name. (so that we can look up symbol names by
    last-component name only).

  - adds a C++ symbol name matcher for symbol_name_match_type::WILD,
    which ignores missing leading specifiers / components.

  - adjusts a few preexisting testsuite tests to use "-qualified" when
    they mean it.

  - adds new testsuite tests.

  - adds unit tests.

Grows the gdb.linespec/ tests like this:

  -# of expected passes           7823
  +# of expected passes           8977

14ad931172 Target FP: Handle interfaces to scripting languages
The last remaing use for DOUBLEST is in the code that interfaces to the
scripting languages (Python and Guile).  The problem here is that we
expose interfaces to convert a GDB value to and from native values of
floating-point type in those languages, and those by definition use
the host floating-point format.

While we cannot completely eliminate conversions to/from the host
floating-point format here, we still need to get rid of the uses
of value_as_double / value_from_double, since those will go away.

This patch implements two new target-float.c routine:
 - target_float_to_host_double
 - target_float_from_host_double
which convert to/from a host "double".  Those should only ever be
used where a host "double" is mandated by an external interface.

	* target-float.c (floatformat_to_host_double): New function.

981a3fb359 Constify add_prefix_cmd
This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.

In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors".  These overloads are temporary; once constification is
complete they can be removed.

This patch also fixes a typo I happened to notice while constifying.

Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build.  So, while I made a best-effort there, I am not
certain they will still compile.

Tested by rebuilding.

0450cc4ce8 Add add_cmd function overloads
This adds two add_cmd overloads: one whose callback takes a const char *,
and one that doesn't accept a function at all.  The no-function overload
was introduced to avoid ambiguity when NULL was passed as the function.

Long term the goal is for all commands to take const arguments, and
for the non-const variants to be removed entirely.

432ae719d3 Fix sometimes-uninitialized warning in gdbscm_value_address

      SCM address;

                  = nullptr

We can get rid of it with a small refactoring.  I think it's a bit
cleaner/safer to initialize address with a pessimistic value and assign
it on success.  Then there's no chance of using it uninitialized.  If I
understand correctly, the NULL check on res_val was to check whether
value_addr threw, and that if value_addr returns without throwing, the
result will never be NULL.  If that's true, we can skip the res_val
variable.

Tested by running gdb.guile/*.exp locally.
