The quick_symbol_functions struct contains a field which is pointer

First, fix a technical problem with the function recurser. The test sets a
watch on local_x at a point where its value is technically undefined. The
test is written assuming that the value is not initially 2, but nothing in the
C standard guarantees that.
Second, augment the existing test for variables in recursive calls to check an
equivalent expression that explicitly sets the scope of the local variable
being tracked.
2012-01-11 Paul Hilfinger <hilfingr@adacore.com>
* gdb.base/watchpoint.c (recurser): Initialize local_x.
(main): Repeat recurser call.
* gdb.base/watchpoint.exp: Check that 'watch recurser::local_x' is
equivalent to 'local_x'.
This test stops inside a recursive function after a few levels of recursion,
goes up some frames, and then accesses a local variable with 'print foo::val'
rather than the usual 'print val' to see if the former pays attention to the
selected frame.
2012-01-11 Paul Hilfinger <hilfingr@adacore.com>
Joel Brobecker <brobecker@adacore.com>
* gdb.base/recpar.c, gdb.base/recpar.exp: New files.
GDB used to search for the frame containing variables in a particular
lexical block starting from the current (top) frame, ignoring any
currently selected frame. It is not clear why this is desirable for
variables that require a frame; why would a user deliberately select
one frame and then expect to see the value of a variable in a more
recent frame? This change causes block_innermost_frame to start
looking from the selected frame, if there is one. It may be
unnecessarily conservative: we use get_selected_frame_if_set rather
than get_selected_frame in order to avoid the side effect of calling
select_frame, which would probably be harmless.
Expression-parsing routines previously made the unwarranted assumption
that all block-qualified variables (written with the GDB extension
<block>::<variable>) are static. As a result, they failed to update
innermost_block, which confused the watch commands about when
variables in watched expressions went out of scope, and also caused
the wrong variables to be watched. This patch also modifies these
routines to treat all local variables the same whether or not they are
block-qualified.
Finally, we add a paragraph to the "Program Variables" section of the texinfo
documentation concerning the use of "::" for accessing non-static variables.
2012-01-11 Paul Hilfinger <hilfingr@adacore.com>
* gdb/blockframe.c (block_innermost_frame): Start search from selected
frame, if present, or otherwise the current frame.

We now use a different script to perform the update. This patch
updates the procedure in our documentation
gdb/doc/ChangeLog:
* gdbint.texinfo (Start of New Year Procedure): Update
to replace use of copyright.sh by use of copyright.py.
The body of this function has been commented out since Jul 1999, and
thus seems unnecessary. While at it, remove some commented out code
that seems to be related to the function being deleted.
gdb/ChangeLog:
* corefile.c (close_exec_file): Delete.
(reopen_exec_file): Remove commented out code that seems related
to close_exec_file, which is being deleted here.
* inferior.h (close_exec_file): Delete.
* fork-child.c (fork_inferior): Remove call to fork_inferior.
This is just a minor cleanup that reduces a bit the code in ada-lang.c
by using skip_spaces or skip_to_space, instead of doing the skipping
ourselves.
gdb/ChangeLog:
* ada-lang.c: #include "cli/cli-utils.h".
(get_selections): Use skip_spaces.
(ada_get_next_arg): Use skip_spaces and skip_to_space.
(catch_ada_exception_command_split): Use skip_spaces.
(ada_decode_assert_location): Likewise.
Trying to insert a breakpoint on `ops."<"', we get the following error:

This is because locate_first_half skips the linespec until the dot,
and the decode_line_internal thinks that the dot might mean that
we have C++ or Java compound. It then tries calling decode_compound
which errors out because it sees the opening angle bracket but not
the closing one (I am guessing).
This patch short-circuits this part of the code when the current
language is Ada.
gdb/ChangeLog:
* linespec.c (decode_line_internal): Check for C++ or Java
compound constructs only if the current language is C, C++
or Java.

on platforms where these descriptors are used and live in a data

This patch now retires the old copyright.sh script which was using
emacs to perform the copyright update. It also completely rewrite
copyright.py to call update-copyright with the appropriate list
of files.
In addition to calling update-copyright, the new script also performs
a sanity-check on all the files that update-copyright could not update,
and sees whether the file might contain a copyright notice that
the script could not decipher.
