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.

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.

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).

exit due to merging the same weak symbol to test that the symbols are
actually weak.

sim: constify sim_write source buffer (part 2)

As pointed out by Sandra Loosemore, a bunch of targets define sim_write
themselves instead of using the common/ code.  So constify them too.

Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Correct PR number for PR corefiles/11481.

Mention PR corefiles/11467.

*** empty log message ***

* i386-linux-tdep.c (i386_linux_regset_sections): Remove extended
register note sections.
(i386_linux_sse_regset_sections, i386_linux_avx_regset_sections):
New variables.

sim: dv-sockser: pass up connected state

A few ports rely on internal dv-sockser state in order to detect whether
a connection has been made (look for 'extern sockser_addr').  Rather than
continuing that tradition, extend the existing status function to return
the socket connection status.

sim: drop PARAMS

The PARAMS macro is no longer useful, so drop it from the sim includes.

* arm.cc (Arm_input_section::set_final_data_size): Compute
accurate final data size instead of using current data size.

sim: constify sim_write source buffer

Most the sim write functions declare their source buffer const because
they only ever read from it.  The global sim_write() function does not
follow this convention though which causes some warnings when trying to
pass it const strings or buffers.

state variables as long as the target supports tracepoints.
(remote_trace_init): Fix prototype.

validate reply.
