* config/tc-ppc.c (md_apply_fix): Hoist code common to insn
and data fixups performing shift/high adjust/sign extension on

[dwarf] Mark all functions as prototyped except C functions.

This makes sure that the types of the arguments are taken into account
when performing an inferior function call to a non-C (or C-like)
function.  In particular, this makes sure that the arguments are
appropriatly converted to the correct type.

For instance, on x86_64-linux, with the following Ada code:

   procedure Set_Float (F : Float) is
   begin
      Global_Float := F;
   end Set_Float;

The following sequence shows that Float arguments are incorrectly
passed (Ada's Float type is the equivalent of type "float" in C):

    (gdb) call set_float (2.0)
    (gdb) print global_float
    $1 = 0.0

Putting a breakpoint inside set_float to inspect the value of
register xmm0 gives the first hint of the problem:

    (gdb) p $xmm0
    $2 = (v4_float => (0 => 0.0, 2.0, 0.0, 0.0),
          v2_double => (0 => 2.0, 0.0),
    [...]

It shows that the argument was passed as a double.

The code responsible for doing appropriate type conversions
for the arguments (value_arg_coerce) found that our function
was not prototyped, and thus could not use typing information
for the arguments. Instead, it defaulted to the value of "set
coerce-float-to-double", which by default is true, to determine
the argument type.

This patch fixes the problem by setting the PROTOTYPE flag
for all functions of any language except C and Objective C.

gdb/ChangeLog:

        * dwarf2read.c (prototyped_function_p): New function.
        (read_subroutine_type): Use it.

not starting at column zero of the line.

[gdbserver/lynx178]: Fix null_ptid -vs- minus_one_ptid confusion in comment

gdb/gdbserver/ChangeLog:

        * lynx-low.c (lynx_resume): Fix null_ptid/minus_one_ptid
        confusion in comment.

gdbserver/lynx178: spurious SIG61 signal when resuming inferior.

On ppc-lynx178, resuming the execution of a program after hitting
a breakpoint sometimes triggers a spurious SIG61 event:

    (gdb) cont
    Continuing.

    Program received signal SIG61, Real-time event 61.
    [Switching to Thread 39]
    0x10002324 in a_test.task1 (<_task>=0x3ffff774) at a_test.adb:30
    30          select  -- Task 1

From this point on, continuing again lets the signal kill the program.
Using "signal 0" or configuring GDB to discard the signal does not
help either, as the program immediately reports the same signal again.

What happens is the following:

  - GDB sends a single-step order to gdbserver: $vCont;s:31
    This tells GDBserver to do a step using thread 0x31=49.
    GDBserver does the step, and thread 49 receives the SIGTRAP
    indicating that the step has finished.

  - GDB then sends a "continue", but this time does not specify
    which thread to continue: $vCont;c
    GDBserver uses an arbitrary thread's ptid to resume the program's
    execution (the current_inferior's ptid was chosen for that).
    See lynx-low.c:lynx_resume:

        if (ptid_equal (ptid, minus_one_ptid))
          ptid = thread_to_gdb_id (current_inferior);

So far on all LynxOS platforms, this has been good enough. But
not so on LynxOS 178. If the ptid used to resume the execution
is not the same as the thread that did the step, we get the weird
signal.

This patch fixes the problem by saving the ptid of the thread
that last caused an event, received during a call to waitpid.
The ptid is saved in per-process private data.

gdb/gdbserver/ChangeLog:

        * lynx-low.c (struct process_info_private): New type.
        (lynx_add_process): New function.
        (lynx_create_inferior, lynx_attach): Replace calls to

        (lynx_resume): If PTID is null, then try using
        current_process()->private->last_wait_event_ptid.
        Add comments.
        (lynx_clear_inferiors): Delete.  The contents of that function
        has been inlined in lynx_mourn;
        (lynx_wait_1): Save the ptid in the process's private data.
        (lynx_mourn): Free the process' private data.  Replace call
        to lynx_clear_inferiors by call to clear_inferiors.

sim: arm: add support for MOVW and MOVT instructions

From: Jayant R. Sonar <Jayant.Sonar@kpitcummins.com>

This patch adds simulator support for handling the armv7 instructions
'movw (immediate)' and 'movt'.

Compiler frequently use these instructions to load the 32bit addresses of
global variables, string pointers etc. into the general registers.

In absence of support of these instructions:
1. GDB run simulator fails to print even simple "hello world" string
   on console.
2. Loading of global variable addresses into the registers fail causing
   arithmetic operation failures.

Patch has been regression tested for arm-none-eabi (-march=armv7-a).

Remove my name from a couple tests.

Tested on x86_64 Fedora 17.

ppc-aix core file relocation.

The current code attempts to provide relocation support when debugging
core files via the rs6000_xfer_partial method of the rs6000-nat
target_ops vector. However, this target_ops vector does not get pushed
on the target stack at all when debugging core files, thus bypassing
completely that part of the code.

into handling the TARGET_OBJECT_LIBRARIES_AIX object.

Float parameter passing in funcall on ppc-aix & ppc-lynx178.

Given the following code:

    float global_float = 0.0;

    void
    set_float (float f)
    {
      global_float = f;
    }

GDB incorrectly calls set_float if the set_float function is marked
as prototyped:

    (gdb) call set_float (5.0)
    (gdb) print global_float
    $1 = 2048

What happens, when the function is marked as prototyped, is that
GDB finds that the argument is a float, casts the value given in
the expression to a float, and then gives that float to ppc-aix/
ppc-lynx178's push_dummy_call gdbarch routine. The latter then blindly
copies it as is in the first floating-point register, instead of
making sure that it has the proper format first.

gdb/ChangeLog:

        * rs6000-aix-tdep.c (rs6000_push_dummy_call): Convert
        floating point registers to register type before storing
        value.
        * rs6000-lynx178-tdep.c (rs6000_lynx178_push_dummy_call):
        Likewise.

* History saving should stay disabled for test cases *

I saw some test cases in gdb.base/default.exp and gdb.base/setshow.exp
are enabling the history saving.
Hence .gdb_history file is modified with history information even
though, by default, we have History saving disabled.
So we should modify GDB test cases so that history saving should stay
off for all test cases.

ChangeLog:

2013-05-13  Muhammad Bilal  <mbilal@codesourcery.com>

       * gdb.base/default.exp: Disable history saving.
       * gdb.base/setshow.exp: Likewise.
