Fix regressions caused by thread-specific breakpoint deletion.

The recent change to make GDB auto-delete thread-specific breakpoints
when the corresponding thread is deleted
(https://sourceware.org/ml/gdb-patches/2013-09/msg00038.html) caused
gdb.base/nextoverexit.exp to regress.

    Breakpoint 1, main () at .../gdb/testsuite/gdb.base/nextoverexit.c:21
    21        exit (0);
    (gdb) next
    [Inferior 1 (process 25208) exited normally]
    Thread-specific breakpoint -5 deleted - thread 1 is gone.
    Thread-specific breakpoint -6 deleted - thread 1 is gone.
    Thread-specific breakpoint -7 deleted - thread 1 is gone.
    Thread-specific breakpoint 0 deleted - thread 1 is gone.
    (gdb) FAIL: gdb.base/nextoverexit.exp: next over exit (the program exited)

We shouldn't be seeing this for internal or momentary breakpoints.  In
fact, we shouldn't even be trying to delete them, as whatever created
them will take care or it, and therefore it's dangerous to delete them
behind the creator's back.

I thought it'd still be good to tag thread-specific internal/momentary
breakpoints such that we'll no longer try to keep them insert in the
target, as they'll cause stops and thread hops in other threads, so I
tried disabling them instead.  That caused a problem when following a
child fork, and detaching from the parent, as we try to reset the
step-resume etc. breakpoints to the new child's thread
(breakpoint_re_set_thread), after the parent thread is already gone
(and the breakpoints are marked disabled).  I fixed that by
re-enabling internal/momentary breakpoints there, but, that didn't
feel super safe either (maybe we'd need a new flag in struct
breakpoint instead, to tag the thread-specific breakpoint as "not to
be inserted").  It felt like I was heading down a design rat hole,
and, other things will usually delete internal/momentary breakpoints
soon enough, so I left that little optimization for some other day.

So, internal/momentary breakpoints are no longer deleted/disabled at
all, and we end up with a one-liner fix.

Tested on x86_64 Fedora 17.

[Hurd/gnu-nat] Fix old "signal-thread" command regression.

By inspection, I noticed that when I made the gnu-nat use
ptid(pid,0,tid) to represent a thread, instead of using ptid(tid,0,0),
in <https://sourceware.org/ml/gdb-patches/2008-08/msg00175.html>, I
introduced a bug.

The change was:

   else
     {
-      int tid = PIDGET (thread_id_to_pid (atoi (args)));
+      int tid = ptid_get_tid (thread_id_to_pid (atoi (args)));
       if (tid < 0)
  error (_("Thread ID %s not known.  Use the \"info threads\" command to\n"
         "see the IDs of currently known threads."), args);

and thread_id_to_pid does:

 ptid_t
 thread_id_to_pid (int num)
 {
   struct thread_info *thread = find_thread_id (num);

   if (thread)
     return thread->ptid;
   else
     return pid_to_ptid (-1);
 }

(pid_to_ptid (-1) is the same as minus_one_ptid.)

So before, we were really looking at the pid, where thread_id_to_pid
stores the -1.

The right fix is to compare the whole ptid to minus_one_ptid, of
course.

Completely untested, but I think it's obvious enough, so I went ahead
and put it in.

PR gdb/11568 - delete thread-specific breakpoints on thread exit

 4       breakpoint     keep y   0x000000000040061f in end at thread-specific-bp.c:29
         breakpoint already hit 1 time

Note that the thread-specific breakpoint 3 stayed around, even though
thread 2 is gone.

There's no way that breakpoint can trigger again (*), so the PR argues
that the breakpoint should just be removed, like local watchpoints.
I'm ambivalent on this -- it could be reasonable to disable the
breakpoint (kind of like breakpoint in shared library code when the
DSO is unloaded), so the user could still use it as visual template
for creating other breakpoints (copy/paste command lists, etc.), or we
could have a way to change to which thread a breakpoint applies.  But,
several people pushed this direction, and I don't plan on arguing...

(*) - actually, there is ...  thread numbers are reset on "run", so
the user could do "break foo thread 2", "run", and expect the
breakpoint to hit again on the second thread.  But given gdb's thread
numbering can't really be stable, that'd only work sufficiently well
for thread 1, so we'd better call it unsupported.

So with the patch, whenever a thread is deleted from GDB's list, GDB
goes through the thread-specific breakpoints and deletes corresponding
breakpoints.  Since this is user-visible, GDB prints out:

  Thread-specific breakpoint 3 deleted - thread 2 is gone.

And of course, we end up with:

 (gdb) info breakpoints

 2       breakpoint     keep y   0x0000000000400614 in start at thread-specific-bp.c:23

The issue is that print_stack_frame always sets the current sal to the
frame's sal.  print_frame_info (which print_stack_frame calls to do
most of the work) also sets the last displayed sal, but only if
print_what isn't LOCATION.  Now the call in question, from within
thread.c:print_thread_info, does pass in LOCATION as print_what, but
print_stack_frame doesn't have the same check print_frame_info has.
We could consider adding it, but setting these globals depending on
print_what isn't very clean, IMO.  What we have is two logically
distinct operations mixed in the same function(s):

  #1 - print frame, in the format specified by {print_what,
    print_level and print_args}.

  #2 - We're displaying a frame to the user, and I want the default
    sal to point here, because the program stopped here, or the user
    did some context-changing command (up, down, etc.).

So I added a new parameter to print_stack_frame & friends for point
#2, and went through all calls in the tree adjusting as necessary.

Tested on x86_64 Fedora 17.

Based on the discussion at:

<https://sourceware.org/ml/gdb-patches/2013-09/msg00301.html>
<https://sourceware.org/ml/gdb-patches/2013-09/msg00383.html>

This patch adds a new convenience function called $_isvoid, whose
only purpose is to check whether an expression is void or not.
This became necessary because the new convenience variable
$_exitsignal (not yet approved) has a mutual exclusive behavior
with $_exitcode, i.e., when one is "defined" (i.e., non-void),
the other is cleared (i.e., becomes void).  Doug wanted a way to
identify which variable to use, and checking for voidness is the
obvious solution.

It is worth mentioning that my first attempt, after a conversation with
Doug, was to actually implement a new $_isdefined() convenience
function.  I would do that (for convenience variables) by calling
lookup_only_internalvar.  However, I found a few problems:

- Whenever I called $_isdefined ($variable), $variable became defined
  (with a void value), and $_isdefined always returned true.

- Then, I tried to implement $_isdefined ("variable"), and do the "$" +
  "variable" inside GDB, thus making it impossible for GDB to create the
  convenience variable.  However, it was hard to extract the string
  without having to mess with values and their idiossincrasies.
  Therefore, I decided to abandon this attempt (specially because I
  didn't want to spend too much time struggling with it).

Anyway, after talking to Doug again we decided that it would be easier
to implement $_isvoid, and this will probably help in cases like
<http://stackoverflow.com/questions/3744554/testing-if-a-gdb-convenience-variable-is-defined>.

I wrote a NEWS entry for it, and some new lines on the documentation.

* remote-sim.c (gdbsim_xfer_inferior_memory): Use
host_address_to_string, and send debug output to gdb_stdlog.

[gdbserver] Garbage collect unused dependency-tracking Makefile variables.

These used to be necessary for manual rule dependency tracking.
Nothing uses them anymore.  (regdat_sh is still needed.)

gdb/gdbserver/
2013-09-06  Pedro Alves  <[email protected]>

* Makefile.in (gdb_proc_service_h, regdef_h, regcache_h)
(signals_def, signals_h, ptid_h, ax_h, agent_h, linux_btrace_h)
(linux_osdata_h, vec_h, gdb_vecs_h, host_defs_h, libiberty_h)
(server_h, gdbthread_h, linux_low_h, linux_ptrace_h)
(gdb_thread_db_h, linux_procfs_h, lynx_low_h, nto_low_h)
(mips_linux_watch_h, i386_low_h, win32_low_h): Delete.

[gdbserver] Update a couple Makefile rules.

These two are still written in the pre-auto-dependency-tracking style.
They probably were written before that, and committed afterwards
without adjustment.  An easy oversight to make.

* Makefile.in (linux-btrace.o, mips-linux-watch.o): Remove
explicit header dependencies and use $COMPILE/$POSTCOMPILE.

[gdbserver] Fix IPA build.

Somehow, my builds yesterdays didn't trip on this...

../src/gdb/gdbserver/linux-amd64-ipa.c: In function ‘initialize_low_tracepoint’:
../src/gdb/gdbserver/linux-amd64-ipa.c:172:3: error: ‘ipa_tdesc’ undeclared (first use in this function)
../src/gdb/gdbserver/linux-amd64-ipa.c:172:3: note: each undeclared identifier is reported only once for each function it appears in

gdb/gdbserver/
2013-09-06  Pedro Alves  <[email protected]>

* linux-amd64-ipa.c: Include tracepoint.h.
* linux-i386-ipa.c: Include tracepoint.h.

Extract Linux-specific portitions of cris-tdep.c to a new file.
This brings in some standard functionality hitherdo missing from
the CRIS/CRISv32 port thanks to the new call to gdbarch_init_osabi,
as well as clearly showing that there is Linux support for this
platform by virtue of the existence of a cris-linux-tdep.c file.

2013-09-06  Ricard Wanderlof  <[email protected]>

* Makefile.in (ALL_TARGET_OBS): Add cris-linux-tdep.o.
* configure.tgt: Add cris-linux-tdep.o and linux-tdep.o to
gdb_target_obs for cris target.
* cris-tdep.c (struct gdbarch_tdep): Move to cris-tdep.h.
(cris_gdbarch_init): Move calls to
set_gdbarch_fetch_tls_load_module_address and
set_solib_svr4_fetch_link_map_offsets to cris-linux-tdep.c.
Add call to gdbarch_init_osabi.
* cris-linux-tdep.c: New file.
* cris-tdep.h: New file.

OBVIOUS: Remove legacy comment referring to deprecated_init_ui_hook.

gdb/ChangeLog

* tui/tui-io.c (tui_initialize_io): Remove legacy comment referring
to deprecated_init_ui_hook.
