The .dg files are files containing the user's code, after the GNAT
expander was applied. The expansion replaces some of the complex
features by simpler pseudo-Ada code and the user can ask to see and
debug that code using the -gnatDG option...
For instance, given the following code where Circle is a tagged type
(aka as a class type in C++):
procedure Foo is
My_Shape : Circle := (X => 1, Y => 2, R => 3);
X : Integer;
begin
X := Position_X (My_Shape);
end Foo;
The expansion results in:
procedure foo is
my_shape : pck__circle := (
_parent => (
_tag => pck__circleP,
x => 1,
y => 2),
r => 3);
x : integer;
begin
x := pck__position_x (my_shape);
return;
end foo;

* symfile.c (init_filename_language_table): Register .dg files
with language_ada.
This is a comment that I wrote not too long ago, I believe, as part
of a submission process, and somehow did not get to commit. It explains
how the TYPE_TARGET_TYPE is used by Ada in the case of dynamic records/
unions.

* gdbtypes.h (struct main_type): Expand comment about target_type
field.
On Darwin, we have lots of complaints being emitted when restarting
a program:
(gdb) start
`a-except.o' has disappeared; keeping its symbols.
`unwind-dw2.o' has disappeared; keeping its symbols.
`s-except.o' has disappeared; keeping its symbols.
`s-traceb.o' has disappeared; keeping its symbols.
These object files are part of the GNAT runtime, and were never available.
The warning comes from the fact that we're checking whether the .o files
in the GNAT shared runtime have changed whereas we should be checking
whether the GNAT shared library itself has changed.
This patch implements this. Although it is really only useful on a platform
such as Darwin (debug info stored in .o files), we believe that this is
the right thing to do in general. This change should be a noop for all
the other platforms in any case.
gdb/ChangeLog (from Tristan Gingold & Pedro Alves):
* symfile.c (reread_symbols): Also search for file in libraries.
Update comment.
Tested on x86_64-darwin and x86_64-linux.
