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).

932539d7a3 Have partial symbol tables own psymbol vectors 
Currently pointers to all partial symbols are stored in two vectors;
and then indices into these vectors are stored in each partial_symtab.

This patch changes this so that each partial symtab instead has
vectors of symbols.  add_psymbol_to_list can now be changed into a
method on partial_symtab as well.

My main motivation for doing this is that I am looking into calling
sort_pst_symbols in the background.  However, I haven't actually
implemented this yet.  (Also this may make it more feasible to also
sort the static psymbols, though I haven't tried that either.)

Also, though, this lets us remove the "current_global_psymbols"
vector, because now the callers can simply refer directly to the
psymtab that they are modifying (formerly this was implicit).

The main drawback of this patch is that it increases the size of
partial symtab.

159ed7d93f gdb: move regcache::regcaches to regcache.c 
I don't really understand why `regcache_thread_ptid_changed` is a static
method of `struct regcache` instead of being a static free function in
regcache.c.  And I don't understand why `current_regcache` is a static
member of `struct regcache` instead of being a static global in
regcache.c.  It's not wrong per-se, but there's no other place where we
do it like this in GDB (as far as I remember) and it just exposes things
unnecessarily in the .h.

Move them to be just static in regcache.c.  As a result,
registers_changed_ptid doesn't need to be friend of the regcache class
anymore.

Removing the include of forward_list in regcache.h showed that we were
missing an include for it in dwarf2/index-write.c, record-btrace.c and
sparc64-tdep.c.

gdb/ChangeLog:

	* regcache.h (class regcache): Remove friend
	registers_changed_ptid.
	<regcache_thread_ptid_changed>: Remove.
	<regcaches>: Remove.
	* regcache.c (regcache::regcaches): Rename to...
	(regcaches): ... this.  Make static.
	(get_thread_arch_aspace_regcache): Update.
	(regcache::regcache_thread_ptid_changed): Rename to...
	(regcache_thread_ptid_changed): ... this.  Update.

	(regcaches_test): Update.
	(_initialize_regcache): Update.
	* sparc64-tdep.c, dwarf2/index-write.c, record-btrace.c: Include
	<forward_list>.

7ab9679411 [gdb/symtab] Enable ada .gdb_index 
Currently the .gdb_index is not enabled for ada executables (PR24713).

Fix this by adding the required support in write_psymbols, similar to how that
is done for .debug_names in debug_names::insert.

Tested on x86_64-linux, with native and target board cc-with-gdb-index.

976ca31673 gdb: rename dwarf2_per_objfile variables/fields to per_objfile 
While doing the psymtab-sharing patchset, I avoided renaming variables
unnecessarily to avoid adding noise to patches, but I'd like to do it
now.  Basically, we have these dwarf2 per-something structures:

  - dwarf2_per_objfile
  - dwarf2_per_bfd
  - dwarf2_per_cu_data

I named the instances of dwarf2_per_bfd `per_bfd` and most of instances
of dwarf2_per_cu_data are called `per_cu`.  Most pre-existing instances
of dwarf2_per_objfile are named `dwarf2_per_objfile`.  For consistency
with the other type, I'd like to rename them to just `per_objfile`.  The
`dwarf2_` prefix is superfluous, since it's already clear we are in
dwarf2 code.  It also helps reducing the line wrapping by saving 7
precious columns.

gdb/ChangeLog:

	* dwarf2/comp-unit.c, dwarf2/comp-unit.h, dwarf2/index-cache.c,
	dwarf2/index-cache.h, dwarf2/index-write.c,
	dwarf2/index-write.h, dwarf2/line-header.c,
	dwarf2/line-header.h, dwarf2/macro.c, dwarf2/macro.h,
	dwarf2/read.c, dwarf2/read.h: Rename struct dwarf2_per_objfile
	variables and fields from `dwarf2_per_objfile` to just
	`per_objfile` throughout.

c3699833af Make dwarf2_get_dwz_file take a dwarf2_per_bfd 
This allows removing a per_bfd->dwarf2_per_objfile reference in
get_abbrev_section_for_cu.

This requires saving the bfd in dwarf2_per_bfd.  The constructor of
dwarf2_per_bfd already accepts the bfd, so it's just a matter of saving
it in a field.

I replaced uses of objfile_name with bfd_get_filename, which should be
equivalent in this case.

gdb/ChangeLog:

	* dwarf2/read.h (struct dwarf2_per_bfd) <obfd>: New member.
	(dwarf2_get_dwz_file): Replace parameter with dwarf2_per_bfd.

	field.

5989a64ed5 Split dwarf2_per_objfile into dwarf2_per_objfile and dwarf2_per_bfd 
This is the first step of splitting dwarf2_per_objfile in two, one
structure for objfile-independent data (dwarf2_per_bfd) and one for
objfile-dependent data (dwarf2_per_objfile).

The existing dwarf2_per_objfile is renamed dwarf2_per_bfd, and a new
dwarf2_per_objfile type is introduced, which sits "in between" the
objfile and dwarf2_per_bfd.

So where we had this before:

  objfile -> dwarf2_per_objfile (*)

we now have this:

  objfile -> dwarf2_per_objfile -> dwarf2_per_bfd (*)

(*) Note that the dwarf2_per_objfile in the former corresponds to
the dwarf2_per_bfd in the latter.

I've done the minimal amount of changes in this patch: following patches
will incrementally move things that are not actually shareable between
objfiles from dwarf2_per_bfd to dwarf2_per_objfile.

Most references to dwarf2_per_objfile objects are changed to
dwarf2_per_objfile->per_bfd.  To avoid many of these replacements, which
would have to be reverted later anyway, I've moved right away the
objfile backlink to the new dwarf2_per_objfile structure in this patch.
I've also moved the read_line_string method, since it references the
objfile backlink, and it's actually not difficult to move.

Once the moves are completed, multiple dwarf2_per_objfile sharing the
same BFD will point to the same single instance of dwarf2_per_bfd (as
long as they don't require relocation).

dwarf2_has_info, where we create these objects, is updated to the new
architecture.

I've had to change the get_gdb_index_contents_ftype typedef and related
functions.  The parameter type was changed from dwarf2_per_objfile to
dwarf2_per_bfd, otherwise the template wouldn't work.

Please excuse the terse ChangeLog entry, I have not listed all the
functions where dwarf2_per_objfile has been changed to
dwarf2_per_objfile->per_bfd.  It would take a considerable amount of
time and would not really be useful in the end.

gdb/ChangeLog:

	* dwarf2/read.h (dwarf2_per_objfile): Rename to dwarf2_per_bfd,
	then introduce a new dwarf2_per_objfile type.

7666722fce [gdb/symtab] Save modules in .debug_names 
When running test-case gdb.fortran/info-modules.exp with target board
debug-names, I run into:
...
FAIL: gdb.fortran/info-modules.exp: info modules: check for entry \
  'info-types-2.f90', '18', 'mod2'
...

In more detail, comparing the behaviour of the executable without and with
.debug_names section, we have:
...
-$ gdb -batch info-modules -ex "info modules"
+$ gdb -batch info-modules.debugnames -ex "info modules"
 All defined modules:

-18:     mod2
-
 File /data/gdb_versions/devel/src/gdb/testsuite/gdb.fortran/info-types.f90:

...

This is due to the fact that the .debug_names section does not contain
DW_TAG_module entries.

08feed99cb Change get_objfile_arch to a method on objfile 
This changes get_objfile_arch to be a new inline method,
objfile::arch.

To my surprise, this function came up while profiling DWARF psymbol
reading.  Making this change improved performance from 1.986 seconds
to 1.869 seconds.  Both measurements were done by taking the mean of
10 runs on a fixed copy of the gdb executable.

...

Looking at the .gdb_index section contents using objdump --dwarf=gdb_index, we
have:
...
CU table:
[  0] 0x0 - 0x2d
[  1] 0x2e - 0xa4
[  2] 0xa5 - 0xc6
[  3] 0xf7 - 0x126
[  4] 0x127 - 0x2de
[  5] 0x2df - 0x300

Address table:
00000000004004a7 00000000004004b2 4

Symbol table:
[489] main: 4 [global, function]
...
We see that both the main symbol, and main address range map to CU 4, which has
offset range 0x127 - 0x2de, while main actually is contained in CU 3 at offset
range 0xf7 - 0x126.

This is caused by this continue in write_gdbindex, which triggers for the PU:
...
      /* CU of a shared file from 'dwz -m' may be unused by this main file.
        It may be referenced from a local scope but in such case it does not
        need to be present in .gdb_index.  */
      if (psymtab == NULL)
       continue;
...
The continue causes the PU to be skipped in the CU table (we can see that the
PU offset range 0xc7-0xf6 is missing) but the references are not taking that
into account.

I've tried fixing this in the optimal way, by updating the references, but ran
into trouble when follow_die_offset tries to find the CU for the inter-CU
ref.  Because the PU is missing from the CU table,
dwarf2_find_containing_comp_unit bisects to the wrong CU.

Fix this by not skipping the PU in the CU table.

Build and reg-tested on x86_64-linux, with native and target boards
cc-with-gdb-index, cc-with-dwz and cc-with-dwz-m.

This in turn lets us change it not to use the objfile obstack for
allocation; obstack allocation for hash tables is a bad practice
because it leads to excess memory use if the table is ever resized.

82ca895718 Move DWARF code to dwarf2/ subdirectory 
This moves all the remaining DWARF code to the new dwarf2
subdirectory.  This is just a simple renaming, with updates to
includes as needed.
