This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

This rewrites registry.h, removing all the macros and replacing it
with relatively ordinary template classes.  The result is less code
than the previous setup.  It replaces large macros with a relatively
straightforward C++ class, and now manages its own cleanup.

The existing type-safe "key" class is replaced with the equivalent
template class.  This approach ended up requiring relatively few
changes to the users of the registry code in gdb -- code using the key
system just required a small change to the key's declaration.

All existing users of the old C-like API are now converted to use the
type-safe API.  This mostly involved changing explicit deletion
functions to be an operator() in a deleter class.

The old "save/free" two-phase process is removed, and replaced with a
single "free" phase.  No existing code used both phases.

The old "free" callbacks took a parameter for the enclosing container
object.  However, this wasn't truly needed and is removed here as
well.

Replace with calls to blockvector::blocks, and the appropriate method
call on the returned array_view.

Same idea as previous patch, but for symtab::objfile.  I find
it clearer without this wrapper, as it shows that the objfile is
common to all symtabs of a given compunit.  Otherwise, you could think
that each symtab (of a given compunit) can have a specific objfile.

symtab::blockvector is a wrapper around compunit_symtab::blockvector.
It is a bit misleadnig, as it gives the impression that a symtab has a
blockvector.  Remove it, change all users to fetch the blockvector
through the compunit instead.

New in this version:

 - Rebase on master, fix a few more issues that appeared.

python-internal.h contains a number of macros that helped make the code
work with both Python 2 and 3.  Remove them and adjust the code to use
the Python 3 functions.

Remove the macro, replace with an equivalent method.

Change-Id: I8f9ecd290ad28502e53c1ceca5006ba78bf042eb

Remove the macro, replace with an equivalent method.

Change-Id: Id6fe2a79c04bcd6c69ccaefb7a69bc06a476288c

Add a getter and a setter for a symtab's compunit_symtab.  Remove the
corresponding macro and adjust all callers.

For brevity, I chose the name "compunit" instead of "compunit_symtab"
the the field, getter and setter names.  Since we are already in symtab
context, the _symtab suffix seems redundant.

Change-Id: I4b9b731c96e3594f7733e75af1e3d01bc0e4fe92

Add a getter and a setter for a compunit_symtab's producer.  Remove the
corresponding macro and adjust all callers.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.

For the avoidance of doubt, all changes in this commits were
performed by the script.

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.

This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...

gdb/ChangeLog

        Update copyright year range in copyright header of all GDB files.

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.

Remove the gdb_py_long_from_ulongest defines and change the Python

Most of the leaks in python tests are due to the fact that many
PyObject xxxxx_dealloc functions are missing the line to free self
or obj such as:
   Py_TYPE (self)->tp_free (self);
or
   Py_TYPE (obj)->tp_free (obj);

With this patch, the number of python tests leaking decreases from 52 to 12.

py-ref.h can really only be included from a specific spot in

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.

        Update copyright year range in all GDB files

Unfortunately, PyGetSetDef's 'name' and 'doc' members are 'char *'
instead of 'const char *', meaning that in order to list-initialize
PyGetSetDef arrays using string literals requires writing explicit
'char *' casts.  For example:

    static PyGetSetDef value_object_getset[] = {
   -  { "address", valpy_get_address, NULL, "The address of the value.",
   +  { (char *) "address", valpy_get_address, NULL,
   +    (char *) "The address of the value.",
	NULL },
   -  { "is_optimized_out", valpy_get_is_optimized_out, NULL,
   -    "Boolean telling whether the value is optimized "
   +  { (char *) "is_optimized_out", valpy_get_is_optimized_out, NULL,
   +    (char *) "Boolean telling whether the value is optimized "
	"out (i.e., not available).",
	NULL },
   -  { "type", valpy_get_type, NULL, "Type of the value.", NULL },
   -  { "dynamic_type", valpy_get_dynamic_type, NULL,
   -    "Dynamic type of the value.", NULL },
   -  { "is_lazy", valpy_get_is_lazy, NULL,
   -    "Boolean telling whether the value is lazy (not fetched yet\n\
   +  { (char *) "type", valpy_get_type, NULL,
   +    (char *) "Type of the value.", NULL },
   +  { (char *) "dynamic_type", valpy_get_dynamic_type, NULL,
   +    (char *) "Dynamic type of the value.", NULL },
   +  { (char *) "is_lazy", valpy_get_is_lazy, NULL,
   +    (char *) "Boolean telling whether the value is lazy (not fetched yet\n\
    from the inferior).  A lazy value is fetched when needed, or when\n\
    the \"fetch_lazy()\" method is called.", NULL },
      {NULL}  /* Sentinel */

We have ~20 such arrays, and I first wrote a patch that fixed all of
them like that...  It's not pretty...

One way to make these a bit less ugly would be add a new macro that
hides the casts, like:

  #define GDBPY_GSDEF(NAME, GET, SET, DOC, CLOSURE) \
     { (char *) NAME, GET, SET, (char *) DOC, CLOSURE }

and then use it like:

    static PyGetSetDef value_object_getset[] = {
       GDBPY_GSDEF ("address", valpy_get_address, NULL,
       		    "The address of the value.", NULL),
       GDBPY_GSDEF ("is_optimized_out", valpy_get_is_optimized_out, NULL,
       		    "Boolean telling whether the value is optimized ", NULL),
      {NULL}  /* Sentinel */
    };

But since we have C++11, which gives us constexpr and list
initialization, I thought of a way that requires no changes where the
arrays are initialized:

We add a new type that extends PyGetSetDef (called gdb_PyGetSetDef),
and add constexpr constructors that accept const 'name' and 'doc', and
then list/aggregate initialization simply "calls" these matching
constructors instead.

I put "calls" in quotes, because given "constexpr", it's all done at
compile time, and there's no overhead either in binary size or at run
time.  In fact, we get identical binaries, before/after this change.

Unlike the fixes that fix some old Python API to match the API of more
recent Python, this switches to using explicit "gdb_PyGetSetDef"
everywhere, just to be clear that we are using our own version of it.

Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

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)

gdb/ChangeLog:

        Update year range in copyright notice of all files.

Currently "symtabs" in gdb are stored as a single linked list of
struct symtab that contains both symbol symtabs (the blockvectors)
and file symtabs (the linetables).

This has led to confusion, bugs, and performance issues.

This patch is conceptually very simple: split struct symtab into
two pieces: one part containing things common across the entire
compilation unit, and one part containing things specific to each
source file.

Example.
For the case of a program built out of these files:

foo.c
  foo1.h
  foo2.h
bar.c
  foo1.h
  bar.h

Today we have a single list of struct symtabs:

objfile -> foo.c -> foo1.h -> foo2.h -> bar.c -> foo1.h -> bar.h -> NULL

where "->" means the "next" pointer in struct symtab.

With this patch, that turns into:

objfile -> foo.c(cu) -> bar.c(cu) -> NULL
            |            |
            v            v
           foo.c        bar.c
            |            |
            v            v
           foo1.h       foo1.h
            |            |
            v            v
           foo2.h       bar.h
            |            |
            v            v
           NULL         NULL

where "foo.c(cu)" and "bar.c(cu)" are struct compunit_symtab objects,
and the files foo.c, etc. are struct symtab objects.

So now, for example, when we want to iterate over all blockvectors
we can now just iterate over the compunit_symtab list.

Plus a lot of the data that was either unused or replicated for each
symtab in a compilation unit now lives in struct compunit_symtab.
E.g., the objfile pointer, the producer string, etc.
I thought of moving "language" out of struct symtab but there is
logic to try to compute the language based on previously seen files,
and I think that's best left as is for now.
With my standard monster benchmark with -readnow (which I can't actually
do, but based on my calculations), whereas today the list requires
77MB to store all the struct symtabs, it now only requires 37MB.
A modest space savings given the gigabytes needed for all the debug info,
etc.  Still, it's nice.  Plus, whereas today we create a copy of dirname
for each source file symtab in a compilation unit, we now only create one
for the compunit.

So this patch is basically just a data structure reorg,
I don't expect significant performance improvements from it.

Notes:

1) A followup patch can do a similar split for struct partial_symtab.
I have left that until after I get the changes I want in to
better utilize .gdb_index (it may affect how we do partial syms).

2) Another followup patch *could* rename struct symtab.
The term "symtab" is ambiguous and has been a source of confusion.
In this patch I'm leaving it alone, calling it the "historical" name
of "filetabs", which is what they are now: just the file-name + line-table.
