fix printing of Ada wide characters on ppc-aix

Same problem as before: We were downcasting the character value from
int to unsigned char, which caused an overflow.  The reason why we did
not see this problem before is probably related to the fact that
we're using stabs on AIX and thus characters types are defined as
a TYPE_CODE_INT (or TYPE_CODE_RANGE?).

gdb/ChangeLog:

        * ada-valprint.c (ada_print_scalar): Remove unsigned char downcast.
        (ada_val_print_1): Likewise.

[powerpc] breakpoint inserted past function end

On powerpc, the prologue scanner reads instruction after instruction,
and just skips instructions that do not affect a frame.  This means
that it does not stop if if finds and unexpected instruction (which
could possibly happen with optimization, I presume). To avoid scanning
too many instructions, it tries to establish an upper limit.

The upper limit is first computed using the debugging (line) info,
but if that fails, it falls back on an arbitrary 100 bytes (or 25
instructions).  The problem is that, if the function is shorter than
those 25 instructions, we run the risk of skipping the entire function
and returning a PC that's outside our function.

In the event where we can find a symbol for a given PC (and therefore
can determine function start and end addresses), but cannot find an
upper limit using skip_prologue_using_sal, then we can at least limit
make sure that the 25 instructions do not put us beyour our function.
If it does, then further reduce the upper-limit to the end of the function.

gdb/ChangeLog:

        * rs6000-tdep.c (rs6000_skip_prologue): Make sure that the prologue
        upper limit address is not greater than the function end address
        when the upper limit could not be computed using the debugging
        info.

    $1 = 57005 '["ad"]'

The integer value is correct (57005 = 0xdead), but the character
representation is not, it should be:

    $1 = 57005 '["dead"]'

Same for Wide_Wide_Characters.

There were two issues:
   (a) The first issue was in ada-valprint, where we were assuming
       that character types were 1 byte long;
   (b) The second problem was in c-valprint, where we were down-casting
       the integer value of the character to type `unsigned char',
       causing use to lose all but the lowest byte.

problem sourcing GDB script in interactive-mode on

When interactive-mode is not auto, GDB always uses that setting to
determine whether to act as if the input stream is a terminal or not.
However, this setting should only be honored if the input stream is
the standard input stream.  Otherwise, we run into trouble while
source-ing a GDB script, as shown below (on x86_64-linux):

        % gdb  -q

The lack of output and the fact that the "print 3" command returned
a value saved in $1 (as opposed to $3) indicates that the script was
not even evaluated at all.

[ia64-hpux] inferior function call support

We have two stacks to deal with on ia64, when making a function call.
The first is the usual stack frame, and the second is the register
stack frame.  On ia64-linux, the register frame is setup by adjusting
the BSP register.  Unfortunately for us, the HP-UX kernel does not allow
the debugger to change the value of the BSP.

To work around that limitation, the method I am using here is to push
some assembly code on the stack. This assembly code contains, among
other things, a call to the alloc insn, which sets up our frame for us.
An extensive comment in ia64-hpux-tdep.c explains the entire procedure.

Despite this approach, most of the code in ia64-tdep.c which sets up
the function call is still applicable - and only a few things need
to be done differently:  For instance, instead of changing the BSP,
we do nothing.  We store the parameters at a different location, etc.
So this patch also adjusts the inf-call code in ia64-tdep.c to make it
a little more extensible: I create a new ia64_infcall_ops structure
which allows an ABI to define how the few things that need to be
differentiated.

Another element that turned out to be necessary but is more of a detail
is that the computation of the linkage pointer needs to be handled
specially for symbols inside shared libraries.  This is especially
visible when calling malloc, which happens everytime memory needs to
be allocated in inferior memory...  The special treatment included
again the necessity to use some routines only available on the host.
So another target object TARGET_OBJECT_HPUX_SOLIB_GOT was created for
that purpose.

        * ia64-tdep.h (struct regcache): Forward declare.
        (struct ia64_infcall_ops): New struct type.

[ia64-hpux] unwinding bsp value from system call

This fixes unwinding from a thread that is stopped inside a system call.
This can be seen when switching to a thread that is stopped doing a
pthread_cond_wait, for instance...

The comments inside the code should explain what is happening in our
case (the HP-UX exception in the case of system calls): Under certain
circumstances (program stopped inside syscall), the offset to apply to
the current BSP in order to compute the previous BSP is not the usual
CFM & 0x7f.

We parts in this patch:

  1. Figuring out that we are stopped inside a syscal: This requires
     a TT_LWP_RUREGS ttrace call, which is not directly possible from
     ia64-tdep.c.  So use defined a new TARGET_OBJECT_HPUX_UREGS object
     to request it from the -nat side.

  2. Add a gdbarch_tdep method that allows us to change the default
     behavior on ia64-hpux, permitting us to have a different "size of

[hpux/ttrace] Determine attached process LWP immediately after attaching.

When attaching to a process, the ttrace interface was creating a ptid
with a null LWP, because it did not have it yet.  This LWP was then
set as soon as we received our first event from our inferior, during
our first wait.  Similarly, the allocation of the thread private info
was also defered.

This works on PA/HP-UX, because we immediately perform a wait to pop
the event triggered by the attach.  We can use that event to extract
the thread's LWP.  But this does not work for IA64/HP-UX, because
the attach no longer triggers an event, and thus a wait should NOT
be performed (such a wait would simply block indefinitely).

It is actually possible, however, to determine the thread's LWP.
This change therefore adjusts the attach code to create a thread with
the correct LWP set, as well as with its private info allocated.
Same thing for all the other threads.

gdb/ChangeLog:

        [ttrace] Compute thread list immediately after attach.

        New subprogram.

[libunwind-frame] handle functions with no minimal symbol/debug info.

This is something that I am seeing on ia64-hpux while trying to
backtrace from a thread that's doing a wait:

    (gdb) task 2
    [Switching to task 2]
    0x9fffffffef52f590 in __ksleep () from /[...]/libc.so.1
    (gdb) bt
    #0  0x9fffffffef52f590 in __ksleep () from /[...]/libc.so.1
    #1  0x9fffffffef73c870 in __sleep_1x1 () from /[...]/libpthread.so.1
    #2  0x9fffffffef738fe0 in __mxn_sleep () from /[...]/libpthread.so.1
    #3  0x9fffffffef675e90 in ?? () from /[...]/libpthread.so.1

The backtrace is incomplete and stops at frame #3, but there are in fact
a few more frames.

The reason why we stopped the backtrace is related to the fact that
we were not able to determine the start address of the function
corresponding to the frame PC.  This is visible at the user level
thanks to the "??" that GDB displayed for frame 3.

We have the following code in libunwind-frame.c:libunwind_frame_cache
which explicitly returns a NULL cache when we couldn't determine the
frame's function address, immediately triggering an end-of-stack
frame_id, thus terminating the backtrace:

   /* We can assume we are unwinding a normal frame.  Even if this is
      for a signal trampoline, ia64 signal "trampolines" use a normal
      subroutine call to start the signal handler.  */
   cache->func_addr = get_frame_func (this_frame);
   if (cache->func_addr == 0
       && get_next_frame (this_frame)
       && get_frame_type (get_next_frame (this_frame)) == NORMAL_FRAME)
     return NULL;

As explained in the comment, I think we can still go on, and use
the unwind record to do the debugging.  This change imlements this
change, and allows us to get the full backtrace.

sim: enable hw_tree_delete in sim_hw_uninstall

I can't find any history for why the call to hw_tree_delete is commented
out, and the VCS history shows that this goes back to the original import
in 2009.  I did find some vague reference to it from 2000 (pretty close
to the original import of code), but no actual details.

Without this call, every new instance of the sim results in all old
previously allocated resources being leaked.  With some devices, this
isn't just memory, it's things like open file descriptors or mmaps.

So if there are pending issues with this, I'd rather we get the sims
sorted out rather than continuing to leak this stuff.  Especially since
the "let's wait for the sims to fix themselves" hasn't actually happened
in the last 10+ years.

sim: check asprintf return values
