a223f1e7a0 procfs.c: Move find_signalled_thread and find_stop_signal.
These two functions are only used from procfs_make_note_section, which
itself is only defined if:

    #if defined (UNIXWARE) || defined (PIOCOPENLWP) || defined (PCAGENT)

So these two functions are unused on mips-irix, and they get flagged
by -Wunused-function. This patch simply moves these functions closer
to the function that uses them, which also has the effect of putting
them inside the same #if block as procfs_make_note_section.  Thus
they are defined only when used.

gdb/ChangeLog:

        * procfs.c (find_signalled_thread, find_stop_signal): Move
        these functions down to define them only when used.

0c3acc0923 Wrong value printed by info locals for dynamic object.
The problem is printing the wrong value for dynamic local variables
when using the "info locals" command. Consider the following code:

   procedure Print (I1 : Positive; I2 : Positive) is
      type My_String is array (I1 .. I2) of Character;
      I : My_String := (others => 'A');
      S : String (1 .. I2 + 3) := (others => ' ');
   begin
      S (I1 .. I2) := String (I); --  BREAK
      Put_Line (S);
   end Print;

After the debugger stopped at BREAK, we try printing all local variables.
Here is what we get:

        (gdb) info locals
        i = "["00"]["00"]"
        s = "["00"]["00"]["00"]["00"]["00"]["00"]["00"]["00"]"

Curiously, printing their value using the "print" command works:

        (gdb) print i
        $1 = "AA"
        (gdb) print s
        $2 = "        "

We traced the problem to trying to get the contents of a variable
(call to value_contents) before "fix'ing" it.  For those not familiar
with the Ada language support, "fixing" a value consists of swapping
the value's dynamic type with a static version that is appropriate
for our actual value.  As a result, the dynamic type was used to
determine the value size, which is zero, and thus the value contents
was empty.

0c4b2e6393 gdb: objc-lang: check symbol name before accessing memory
The current ObjC logic will check both the symbol name and the target
address space when trying to locate an appropriate selector.  The problem
is that first the target address space is checked before the symbol name.
This may lead to a lot of unnecessary host<->target transactions when
dealing with a non-OjbC target that does use function descriptors to
describe functions as every symbol will have its FD read just to have the
result thrown away with non-matching symbol names.

It also may lead to problems when a non-FD symbol is found that points near
the end of the address space as the target will throw up a memory_error().
One such example are symbols that are not functions, smaller than a FD,
and are the last valid location.  Obviously treating it as a larger data
struct can cause memory overflows.

So to speed things up and not screw over such targets, check the symbol
name (which we already have locally) first before attempting to read the
function's descriptor.  This fixes breakpoints with Blackfin Linux FDPIC
ELFs, and seems to cause no native regressions on my x86_64/Linux system.

cb7db0f2a9 gdb: fdpic/frv: fix shared library loading
The recent change to reload_shared_libraries() broke FDPIC shared libraries as
the solib-frv.c code was implicitly relying on the initial order of calls
(first solib_addr() and then solib_create_inferior_hook()).  It was
maintaining internal state via enable_break{1,2}_done to handle this.

While I could tweak these values a bit more, the original code wasn't terribly
bullet proof -- if during the initial debug you attempted to view shared
libraries, the enable2_break() code would whine about the ldso internal debug
addresses being unfetchable (and would actually attempt to read address 0x8 on
the target).  So I've dropped this implicit dependency on order (i.e.
enable_break1_done) and updated the ldso poking code (i.e. enable_break2) to
silently return when the internal debug address is still set to 0.  It will
remain this way until the ldso gets a chance to initialize at which point the
code will act the same as before.

While I have no way of testing the FRV, the Blackfin FDPIC code is using this
same base in a 100% copy & paste method since we implemented FDPIC the same
way as the FRV guys (I'll address this in the future).  This fix was required
in order to handle shared libraries with Blackfin FDPIC properly, and I see no
reason why it wouldn't also work for FRV (since the uClibc ldso FDPIC code is
the same too and that's really what this is poking).

0d18d7205b gdb: constify remote files_info
The sim and m32r remote targets declare a local "file" variable and only
assign const strings to it before passing it to a printf() func.  So add
const markings to avoid gcc warnings like:
gdb/remote-sim.c: In function 'gdbsim_files_info':
gdb/remote-sim.c:789: warning: initialization discards qualifiers
	from pointer target type
