This is incorrect, it should return an object which has one child

we need to apply a small transformation in order to get their actual
type. This is already done on the GDB/CLI side in ada-valprint,

Ada: Fix missing call to pretty-printer for fields of records.

Consider the following types:

   type Time_T is record
      Secs : Integer;
   end record;
   Before : Time_T := (Secs => 1384395743);

In this example, we assume that type Time_T is the number of seconds
since Epoch, and so added a Python pretty-printer, to print this
type in a more human-friendly way. For instance:

    (gdb) print before
    $1 = Thu Nov 14 02:22:23 2013 (1384395743)

However, we've noticed that things stop working when this type is
embedded inside another record, and we try to print that record.
For instance, with the following declarations:

   type Composite is record
      Id : Integer;
      T : Time_T;
   end record;
   Afternoon : Composite := (Id => 1, T => (Secs => 1384395865));

    (gdb) print afternoon
    $2 = (id => 1, t => (secs => 1384395865))

    (gdb) print afternoon
    $2 = (id => 1, t => Thu Nov 14 02:24:25 2013 (1384395865))

This patch fixes the problem by making sure that we try to print
each field via a call to val_print, rather than calling ada_val_print
directly. We need to go through val_print, as the val_print
handles all language-independent features such as calling the
pretty-printer, knowing that ada_val_print will get called eventually
if actual Ada-specific printing is required (which should be the
most common scenario).

And because val_print takes the language as parameter, we enhanced
the print_field_values and print_variant_part to also take a language.
As a bonus, this allows us to remove a couple of references to
current_language.

Split ada_val_print_1 into smaller functions

The idea of this patch is that it's hard to have a global view of
ada_val_print_1 because its body spans over too many lines. Also,
each individual "case" block within the giant "switch" can be hard
to isolate if spanning over multiple pages as well.

Remove call to gdb_flush at end of ada_val_print_1

I am not sure why this function was called in the first place, but
it disrupts the printing flow when in GDB/MI mode, ending the current
console stream output, and starting a new one. It's not clear whether,
with the code as currently written, the problem is actually visible
or only latent. But, it becomes visible when we replace one of the
"return" statements in the "switch" block just above by a "break"
statement (this is something I'd like to do, and what made me realize
the problem). With the gdb_flush call (after having replaced the
"return" statement as explained above), we get:

        % gdb -q -i=mi ada_prg

  !! -> ~"$1 = 1"

Consider the following declarations:

    typedef long our_time_t;
    our_time_t current_time = 1384395743;

The purpose of this patch is to allow the use of a pretty-printer
for variables of type our_time_t.  Normally, pretty-printing sniffers
use the tag name in order to determine which, if any, pretty-printer
should be used. But in the case above, the tag name is not set, since
it does not apply to integral types.

This patch extends the gdb.Type list of attributes to also include
the name of the type, thus allowing the sniffer to match against
that name. With that change, I was able to write a pretty-printer
which displays our variable as follow:

    (gdb) print current_time

Extend handling of immediates on ARM's SystemTap SDT probe support

parser handles literal numbers (immediates).

Implement SystemTap SDT probe support for AArch64

This commit implements the needed bits for SystemTap SDT probe support
on AArch64 architectures.

First, I started by looking at AArch64 assembly specification and
filling the necessary options on gdbarch's stap machinery in order to
make the generic asm parser (implemented in stap-probe.c) recognize
AArch64's asm.

After my last patch for the SystemTap SDT API, which extends it in order
to accept multiple prefixes and suffixes, this patch became simpler.  I
also followed Marcus suggestion and did not shared code between 32- and
64-bit ARM.

Tom asked me in a previous message how I did my tests.  I believe I
replied that, but just in case: I ran the tests on
gdb.base/stap-probe.exp by hand.  I also managed to run the tests on
real hardware, and they pass without regressions.

to catch any syscall 0 (such as syscall read on Linux/x86_64). GDB was
not able to catch the syscall and was missing the breakpoint.

Now, breakpoint_hit_catch_syscall returns immediately when it finds the
correct syscall number, avoiding a following check for the end of the
search vector, that returns a no hit if the syscall number was zero.

Testcase rationale
==================
by: Sergio Durigan Junior

This testcase is a little difficult to write.  By doing a quick
inspection at the Linux source, one can see that, in many targets, the
syscall number 0 is restart_syscall, which is forbidden to be called
from userspace.  Therefore, on many targets, there's just no way to test
this safely.

My decision was to take the simpler route and just adds the "read"
syscall on the default test.  Its number on x86_64 is zero, which is
"good enough" since many people here do their tests on x86_64 anyway and
it is a popular architecture.

However, there was another little gotcha.  When using "read" passing 0
as the third parameter (i.e., asking it to read 0 bytes), current libc
implementations could choose not to effectively call the syscall.
Therefore, the best solution was to create a temporary pipe, write 1
byte into it, and then read this byte from it.
