90fe61ced1 gdb/python: don't use the 'p' format for parsing args
When running the gdb.python/py-arch.exp tests on a GDB built
against Python 2 I ran into some errors.  The problem is that this
test script exercises the gdb.Architecture.integer_type method, and
this method uses 'p' as an argument format specifier in a call to
gdb_PyArg_ParseTupleAndKeywords.

Unfortunately this specified was only added in Python 3.3, so will
cause an error for earlier versions of Python.

This commit switches to use the 'O' specifier to collect a PyObject,
and then uses PyObject_IsTrue to convert the object to a boolean.

An earlier version of this patch incorrectly switched from using 'p'
to use 'i', however, it was pointed out during review that this would
cause some changes in behaviour, for example both of these will work
with 'p', but not with 'i':

  gdb.selected_inferior().architecture().integer_type(32, None)
  gdb.selected_inferior().architecture().integer_type(32, "foo")

The new approach of using 'O' works fine with these cases.  I've added
some new tests to cover both of the above.

There should be no user visible changes after this commit.

d3771fe234 Add gdb.Architecture.integer_type Python function
This adds a new Python function, gdb.Architecture.integer_type, which
can be used to look up an integer type of a given size and
signed-ness.  This is useful to avoid dependency on debuginfo when a
particular integer type would be useful.

v2 moves this to be a method on gdb.Architecture and addresses other
review comments.

8b87fbe6bb gdb/python: new gdb.architecture_names function
Add a new function to the Python API, gdb.architecture_names().  This
function returns a list containing all of the supported architecture
names within the current build of GDB.

The values returned in this list are all of the possible values that
can be returned from gdb.Architecture.name().

8e3685bf25 gdb: delay python initialisation until gdbpy_finish_initialization
Delay Python initialisation until gdbpy_finish_initialization.

This is mostly about splitting the existing gdbpy_initialize_*
functions in two, all the calls to register_objfile_data_with_cleanup,
gdbarch_data_register_post_init, etc are moved into new _initialize_*
functions, but everything else is left in the gdbpy_initialize_*
functions.

Then the call to do_start_initialization (in python/python.c) is moved
from the _initialize_python function into gdbpy_finish_initialization.

There should be no user visible changes after this commit.

f99b517750 Remove redundant typedefs
I was inspired by this patch of Simon's:

https://sourceware.org/pipermail/gdb-patches/2020-November/173522.html

... to remove other typedefs that are no longer necessary now that gdb
uses C++.

I didn't remove absolutely every one -- I didn't touch the tdep files.
However, I removed many of them.  In some cases, I removed an existing
different struct tag.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

d1cab9876d Don't use gdb_py_long_from_ulongest
Remove the gdb_py_long_from_ulongest defines and change the Python
layer to prefer gdb_py_object_from_ulongest.  While writing this I
noticed that the error handling in archpy_disassemble was incorrect --
it could call PyDict_SetItemString with a NULL value.  This patch also
fixes this bug.

64cb3757a9 gdb/python: New method to access list of register groups
Add a new method gdb.Architecture.register_groups which returns a new
object of type gdb.RegisterGroupsIterator.  This new iterator then
returns objects of type gdb.RegisterGroup.

Each gdb.RegisterGroup object just wraps a single reggroup pointer,
and (currently) has just one read-only property 'name' that is a
string, the name of the register group.

As with the previous commit (adding gdb.RegisterDescriptor) I made
gdb.RegisterGroup an object rather than just a string in case we want
to add additional properties in the future.

gdb/ChangeLog:

	* NEWS: Mention additions to Python API.
	* python/py-arch.c (archpy_register_groups): New function.
	(arch_object_methods): Add 'register_groups' method.

0f767f942b gdb/python: Add gdb.Architecture.registers method
This commit adds a new method gdb.Architecture.registers that returns
an object of the new type gdb.RegisterDescriptorIterator.  This
iterator returns objects of the new type gdb.RegisterDescriptor.

A RegisterDescriptor is not a way to read the value of a register,
this is already covered by Frame.read_register, a RegisterDescriptor
is simply a way to discover from Python, which registers are
available for a given architecture.

I did consider just returning a string, the name of each register,
instead of a RegisterDescriptor, however, I'm aware that it we don't
want to break the existing Python API in any way, so if I return just
a string now, but in the future we want more information about a
register then we would have to add a second API to get that
information.  By going straight to a descriptor object now, it is easy
to add additional properties in the future should we wish to.

Right now the only property of a register that a user can access is
the name of the register.

In future we might want to be able to ask the register about is
register groups, or its type.

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.

The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

3fabc0163a Do not include py-ref.h in most files
py-ref.h can really only be included from a specific spot in
python-internal.h.  The other includes are not useful, and cause
compilation errors if the includes are ever sorted.  So, remove these
includes.

Arguably, py-ref.h should simply not be a separate header.

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.

2adadf5170 -Wwrite-strings: Add a PyArg_ParseTupleAndKeywords "const char *" overload
-Wwrite-strings flags code like:

   static char *keywords[] = {"command", "from_tty", "to_string", NULL };

as needing "(char *)" casts, because string literals are "const char []".

We can get rid of the casts by changing the array type like this:

 -  static char *keywords[] = {"command", "from_tty", "to_string", NULL };
 +  static const char *keywords[] = {"command", "from_tty", "to_string", NULL };

However, passing the such array to PyArg_ParseTupleAndKeywords no longer
works OOTB, because PyArg_ParseTupleAndKeywords expects a "char **":

  PyArg_ParseTupleAndKeywords(PyObject *args, PyObject *kw,
                              const char *format,
			      char *keywords[], ...);

and "const char **" is not implicitly convertible to "char **".  C++
is more tolerant that C here WRT aliasing, and a const_cast<char **>
is fine.  However, to avoid having all callers do the cast themselves,
this commit defines a gdb_PyArg_ParseTupleAndKeywords function here
with a corresponding 'keywords' parameter type that does the cast in a
single place.

d7e747318f Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond.  It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.

- mem_fileopen -> string_file

mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack.  This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)

string_file's internal buffer is a std::string, thus the "string" in
the name.  This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.

- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone

The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer.  This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside.  With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.

Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.

With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.

- New ui_file::printf, ui_file::puts, etc. methods

These simplify / clarify client code.  I considered splitting
client-code changes, like these, e.g.:

  -  stb = mem_fileopen ();
  -  fprintf_unfiltered (stb, "%s%s%s",
  -		      _("The valid values are:\n"),
  -		      regdesc,
  -		      _("The default is \"std\"."));
  +  string_file stb;
  +  stb.printf ("%s%s%s",
  +	      _("The valid values are:\n"),
  +	      regdesc,
  +	      _("The default is \"std\"."));

In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc..  I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".

- gdb_fopen replaced with stack-based objects

This avoids the need for cleanups or unique_ptr's.  I.e., this:

      struct ui_file *file = gdb_fopen (filename, "w");
      if (filename == NULL)
 	perror_with_name (filename);
      cleanups = make_cleanup_ui_file_delete (file);
      // use file.
      do_cleanups (cleanups);

is replaced with this:

      stdio_file file;
      if (!file.open (filename, "w"))
 	perror_with_name (filename);
      // use file.

- odd contorsions in null_file_write / null_file_fputs around when to
  call to_fputs / to_write eliminated.

- Global null_stream object

A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.

- TUI's tui_sfileopen eliminated.  TUI's ui_file much simplified

The TUI's ui_file was serving a dual purpose.  It supported being used
as string buffer, and supported being backed by a stdio FILE.  The
string buffer part is gone, replaced by using of string_file.  The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

12c58cd4dc Avoid -Wduplicated-cond warnings in gdb/python
I tried building gdb with -Wduplicated-cond.  This patch fixes the
simpler issue that was found.

In Python 3, "int" and "long" are synonyms, so code like:

      else if (PyLong_Check (obj))
...
      else if (PyInt_Check (obj))

.... will trigger this warning.  The fix is to conditionalize the
PyInt_Check branches on Python 2.

Tested by rebuilding, with both version of Python, on x86-64 Fedora 24.

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++.

e36122e9d7 Fix redefinition errors in C++ mode
In C, we can forward declare static structure instances.  That doesn't
work in C++ though.  C++ treats these as definitions.  So then the
compiler complains about symbol redefinition, like:

 src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’
 src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here

The intent of static here is naturally to avoid making these objects
visible outside the compilation unit.  The equivalent in C++ would be
to instead define the objects in the anonymous namespace.  But given
that it's desirable to leave the codebase compiling as both C and C++
for a while, this just makes the objects extern.

(base_breakpoint_ops is already declared in breakpoint.h, so we can
just remove the forward declare from breakpoint.c)
