[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

PR gdb/11568 is about thread-specific breakpoints being left behind
when the corresponding thread exits.

Currently:

 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

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.

<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  <palves@redhat.com>

* 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)

(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.

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)

* 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  <ricardw@axis.com>

* Makefile.in (ALL_TARGET_OBS): Add cris-linux-tdep.o.

gdb_target_obs for cris target.
* cris-tdep.c (struct gdbarch_tdep): Move to cris-tdep.h.
(cris_gdbarch_init): Move calls to

dwarf2loc.c: minor cleanup. don't print integer with paddress.

A couple years ago, dwarf_expr_fetch used to return a CORE_ADDR.  It
was made to return a ULONGEST since, and the 'dwarf_regnum' local
adjusted accordingly, but, we kept printing it with paddress.
gdbarch_dwarf2_reg_to_regnum takes the register number as 'int', so
there's really no point in using ULONGEST/pulongest either.

* MAINTAINERS: Remove avr maintainership.

Rework value_of_register in terms of value_of_register_lazy.

I noticed that value_of_register (used for getting values _of_
registers ($pc, $rax, etc.), rather than variables _in_ registers),
kind of builds a franken-value, by propagating the lval and address of
the frame register value, but not the entire location, like necessary
for lval_computed (if some unwinder ever returns that, the resulting
value will misbehave).  This gets in the way of printing optimized out
(not saved) lval_registers differently from other optimized out
values, as it doesn't make sure the resulting value is lval_register.

I started out by just doing something like:

-  VALUE_LVAL (reg_val) = lval;
-  set_value_address (reg_val, addr);
+  VALUE_LVAL (reg_val) = lval_register;

... just like value_of_register_lazy below.  That's sufficient to fix
the issue.

Then I noticed this is using frame_register, which we should avoid
nowadays, for it returns elements of a value, but not all that's
sometimes necessary (unavailable-ness is all or nothing with it, for
instance), and considered using get_frame_register_value instead
(which returns a struct value), and value_contents_copy, just like
value_fetch_lazy's handling of lval_register.  But at that point, I
realized we might as well just defer all that work to
value_of_register_lazy/value_fetch_lazy...

Doing it this way adds a frame_find_by_id lookup (from within
value_fetch_lazy), while we already have a frame pointer handy in
value_of_register.  I considered factoring out the lazy register
fetching out of value_fetch_lazy, into a function that takes a frame
pointer and call that instead, avoiding the lookup, but then it looked
like too much complication for an early optimization, and went back to
keeping it simple.

Tested on x86_64 Fedora 17.

[TUI] Rewrite register-changed decision bits.

I stumbled on the TUI's register-changed decision code before (used to
decided whether the register should be highlighted in the register
window), for it is trying to compare all the different possible states
and contents or previous/current register contents, and as such may
need updating whenever the value machinery changes to have more state.
It's just much simpler and more future proof to compare the
previous/current printable representation instead.

The bit in tui_register_format that returns early if the register has
no name gets a bit in the way of the new prototype (what to return in
that case? NULL, empty string, etc.?).  Fortunately, that check isn't
really necessary.  All the callers will have already skipped unnamed
registers.

* tui/tui-regs.c (tui_register_format): Don't look at the
register's name here.  Return string representing register

(tui_get_register): Compare register string representations
instead of register value states and contents.

[PR tui/15933] TUI shows registers of the wrong frame the first time

I've stumbled on this by inspection.

When the TUI's register window is first displayed, it always shows the
registers of the current frame, instead of of the selected frame,
which is obviously bogus.

E.g.,

 (gdb) step             # into "function"
 (gdb) up
 (gdb) tui reg general  # or C-x 2, C-x 2

shows the registers of "function", rather than the caller's.

A subsequent:

 (gdb) frame

or

 (gdb) down
 (gdb) up

can be used as workaround to "fix" it.
