This replaces "the the" with "the" in various comments.

Tested by rebuilding.  This didn't test the solib-dsbt.c change, but
it looks harmless.

This commit applies all changes made after running the gdb/copyright.py
script.

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

gdb/ChangeLog:

	Update copyright year range in all GDB files.

The following will segfault on aarch64 if foo is in another object,
was compiled as c++ and has no debug symbols:
(gdb) p (int)foo()

This is because aarch64_push_dummy_call determines the return type
of the function and then does not check for null pointer.

A null pointer for the return type means the call has no debug
information.  For the code to get here, then the call must have
been cast, otherwise we'd error out sooner.  In the case of a
no-debug-info call cast, the return type is the type the user
had cast the call to, but we do not have that information
available here.

However, aarch64_push_dummy_call only requires the return type in
order to calculate lang_struct_return. This information is available
in the return_method enum. The fix is to simply use this instead.

Adds testcase to check calls across objects, with all combinations
of c, c++, debug and no debug.

Consider the gdb.ada/array_return.exp testcase, and in particular,
consider the following code...

   type Small_Float_Vector is array (1 .. 2) of Float;

   function Create_Small_Float_Vector return Small_Float_Vector is
   begin
      return (others => 4.25);
   end Create_Small_Float_Vector;

... which declares a type which is an array with 2 floats in it
(floats are 4 bytes on AArch64), trying to get GDB to print
the return value from that function does not work:

    (gdb) fin
    Run till exit from #0  pck.create_small_float_vector () at /[...]/pck.adb:15
    0x000000000000062c in p () at /[...]/p.adb:11
    11         Vector := Create_Small_Float_Vector;
    Value returned is $1 = (4.25, 0.0)
                                  ^^^
                                  |||

We expected the value shown to be:

    (gdb) fin
    Run till exit from #0  pck.create_small_float_vector () at /[...]/pck.adb:15
    0x000000000000062c in p () at /[...]/p.adb:11
    11         Vector := Create_Small_Float_Vector;
    Value returned is $1 = (4.25, 4.25)

Because the return type is an HFA, it is returned via the first two
SIMD registers. However, what happens is that the current implementation
fails to realize that this is an HFA, and therefore fetches the return
value from the wrong location. And the reason why it fails to realize
this is because it thinks that our array has 8 elements (HFAs have
a maximum of 4). Looking at aapcs_is_vfp_call_or_return_candidate_1,
where this is determined, we can easily see why (looks like a thinko):

        | case TYPE_CODE_ARRAY:
        | [...]
        |         struct type *target_type = TYPE_TARGET_TYPE (type);
        |         int count = aapcs_is_vfp_call_or_return_candidate_1
        |                       (target_type, fundamental_type);
        |
        |         if (count == -1)
        |           return count;
        |
  !! -> |         count *= TYPE_LENGTH (type);
        |           return count;

Here, we first determine the count for one element of our array,
and so we should then be multiplying that count by the number
of elements in our array (2 in our case). But instead, we multiply it
by the total size (8). As a result, we do not classify the return
type as an HFA, and thus pick the wrong location for fetching
the return value.

        * aarch64-tdep.c (aapcs_is_vfp_call_or_return_candidate_1):

This patch if the first patch in a series to add the ability to add constraints
to system registers that an instruction must adhere to in order for the register
to be usable with that instruction.

These constraints can also be used to disambiguate between registers with the
same encoding during disassembly.

This patch adds a new flags entry in the sysreg structures and ensures it is
filled in and read out during assembly/disassembly. It also adds the ability for
the assemble and disassemble functions to be able to gracefully fail and re-use
the existing error reporting infrastructure.

The return type of these functions are changed to a boolean to denote success or
failure and the error structure is passed around to them. This requires
aarch64-gen changes so a lot of the changes here are just mechanical.

This patch fixes tagged pointer support for AArch64 GDB. Linux kernel
debugging failure was reported after tagged pointer support was committed.

After a discussion around best path forward to manage tagged pointers
on GDB side we are going to disable tagged pointers support for
aarch64-none-elf-gdb because for non-linux applications we cant be
sure if tagged pointers will be used by MMU or not.

Also for aarch64-linux-gdb we are going to sign extend user-space
address after clearing tag bits. This will help debug both kernel
and user-space addresses based on information from linux kernel
documentation given below:

According to AArch64 memory map:
https://www.kernel.org/doc/Documentation/arm64/memory.txt

"User addresses have bits 63:48 set to 0 while the kernel addresses have
the same bits set to 1."

According to AArch64 tagged pointers document:
https://www.kernel.org/doc/Documentation/arm64/tagged-pointers.txt

The kernel configures the translation tables so that translations made
via TTBR0 (i.e. userspace mappings) have the top byte (bits 63:56) of
the virtual address ignored by the translation hardware. This frees up
this byte for application use.

Running gdb testsuite after applying this patch introduces no regressions
and tagged pointer test cases still pass.

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

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

Tested by the buildbot.

class readable_regcache and pass readable_regcache to gdbarch pseudo_register_read and pseudo_register_read_value

pseudo registers are either from raw registers or memory, so
gdbarch methods pseudo_register_read and pseudo_register_read_value
should have regcache object which only have read methods.  In other
words, we should disallow writing to regcache in these two gdbarch
methods.  In order to apply this restriction, this patch adds a new
class readable_regcache, derived from reg_buffer, and it only has
raw_read and cooked_read methods.  regcache is derived from
readable_regcache.  This patch also passes readable_regcache instead of
regcache to gdbarch methods pseudo_register_read and
pseudo_register_read_value.

This patch moves raw_read* and cooked_read* methods to readable_regcache,
which is straightforward.  One thing not straightforward is that I split
regcache::xfer_part to readable_regcache::read_part and regcache::write_part,
because readable_regcache can only have methods to read.

readable_regcache is an abstract base class, and it has a pure virtual
function raw_update, because I don't want readable_regcache know where
these raw registers are from.  They can be from either the target
(readwrite regcache) or the regcache itself (readonly regcache).

gdb/ChangeLog:

        Update copyright year range in all GDB files

ARMv8 supports tagged address, that is, the top one byte in address
is ignored.  It is always enabled on aarch64-linux.  See
https://www.kernel.org/doc/Documentation/arm64/tagged-pointers.txt

The tag in the tagged address is modeled as non-significant bits in
address, so this patch adds a new gdbarch method significant_addr_bit and
clear the non-significant bits (the top byte in ARMv8) of the virtual
address at the point before passing address to target cache layer.  IOW,
the address used in the target cache layer is already cleared.

Before this patch,
(gdb) x/x 0x0000000000411030
0x411030 <global>:	0x00000000
(gdb) x/x 0xf000000000411030
0xf000000000411030:	Cannot access memory at address 0xf000000000411030

After this patch,

(gdb) x/x 0x0000000000411030
0x411030 <global>:	0x00000000
(gdb) x/x 0xf000000000411030
0xf000000000411030:	0x00000000

Note that I used address_significant in paddress, but it causes a
regression gdb.base/long_long.exp, because gdb clears the non-significant
bits in address, but test still expects them.

p/a val.oct^M
$24 = 0x2ee53977053977^M
(gdb) FAIL: gdb.base/long_long.exp: p/a val.oct

so I defer the change there.

This patches removes get_regcache_arch, and use regache->arch () instead.

regcache->arch ().  On the other hand, this patch shortens the code a
little bit.

displaced_step_closure is a type defined in multiple -tdep.c files.
Trying to xfree it from the common code (infrun.c) is a problem when we
try to poison xfree for non-POD types.  Because there can be multiple of
these types in the same build, this patch makes a hierarchy of classes
with a virtual destructor.  When the common code deletes the object
through a displaced_step_closure pointer, it will invoke the right
destructor.

The amd64 used a last-member array with a variable size.  That doesn't
work with new, so I changed it for an std::vector.  Other architectures
which used a simple byte buffer as a closure now use a shared
buf_displaced_step_closure, a closure type that only contains a
gdb::byte_vector.

Reg-tested on the buildbot.

This patch is an initial C++-ification of pv_area, from
prologue-value.  It turns pv_area into a class with a constructor and
destructor; renames the data members; and changes various functions to
be member functions.  This allows the removal of
make_cleanup_free_pv_area.

As a first small step to getting rid of doublest.h, this patch removes the
include of "floatformat.h" in "doublest.h".  This is actually not needed
for the file itself.  A few source files now need to include "floatformat.h"
directly, since they got it indirectly via "doublest.h" and still need it.

In reviewing which files need it, I found a number of files that include
"floatformat.h" directly without actually needing it at all.  Similarly,
a number of files include "doublest.h" without needing it.  I've also
removed those unnecessary include statements.

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

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

or with gdbserver:

  ./gdbserver --selftest=aarch64

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

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

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

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

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