Jan Kratochvil ed12ef62cc introduce call_function_by_hand_dummy 
This provides a variant of call_function_by_hand that allows the dummy
frame destructor to be set.  This is used by the compiler code to
manage some resources when calling the gdb-generated inferior
function.

	* infcall.h (call_function_by_hand_dummy): Declare.
	* infcall.c (call_function_by_hand): Use
	call_function_by_hand_dummy.
	(call_function_by_hand_dummy): Rename from call_function_by_hand.
	Add arguments.  Register a destructor.

Gary Benson c765fdb902 Remove spurious exceptions.h inclusions 
defs.h includes utils.h, and utils.h includes exceptions.h.  All GDB
.c files include defs.h as their first line, so no file other than
utils.h needs to include exceptions.h.  This commit removes all such
inclusions.

Pedro Alves 705096250d Always pass signals to the right thread 
Currently, GDB can pass a signal to the wrong thread in several
different but related scenarios.

E.g., if thread 1 stops for signal SIGFOO, the user switches to thread
2, and then issues "continue", SIGFOO is actually delivered to thread
2, not thread 1.  This obviously messes up programs that use
pthread_kill to send signals to specific threads.

This has been a known issue for a long while.  Back in 2008 when I
made stop_signal be per-thread (2020b7ab), I kept the behavior -- see
code in 'proceed' being removed -- wanting to come back to it later.
The time has finally come now.

The patch fixes this -- on resumption, intercepted signals are always
delivered to the thread that had intercepted them.

Another example: if thread 1 stops for a breakpoint, the user switches
to thread 2, and then issues "signal SIGFOO", SIGFOO is actually
delivered to thread 1, not thread 2, because 'proceed' first switches
to thread 1 to step over its breakpoint...  If the user deletes the
breakpoint before issuing "signal FOO", then the signal is delivered
to thread 2 (the current thread).

"signal SIGFOO" can be used for two things: inject a signal in the
program while the program/thread had stopped for none, bypassing
"handle nopass"; or changing/suppressing a signal the program had
stopped for.  These scenarios are really two faces of the same coin,
and GDB can't really guess what the user is trying to do.  GDB might
have intercepted signals in more than one thread even (see the new
signal-command-multiple-signals-pending.exp test).  At least in the
inject case, it's obviously clear to me that the user means to deliver
the signal to the currently selected thread, so best is to make the
command's behavior consistent and easy to explain.

Then, if the user is trying to suppress/change a signal the program
had stopped for instead of injecting a new signal, but, the user had
changed threads meanwhile, then she will be surprised that with:

  (gdb) continue
  Thread 1 stopped for signal SIGFOO.
  (gdb) thread 2
  (gdb) signal SIGBAR

... GDB actually delivers SIGFOO to thread 1, and SIGBAR to thread 2
(with scheduler-locking off, which is the default, because then
"signal" or any other resumption command resumes all threads).

So the patch makes GDB detect that, and ask for confirmation:

  (gdb) thread 1
  [Switching to thread 1 (Thread 10979)]
  (gdb) signal SIGUSR2
  Note:
    Thread 3 previously stopped with signal SIGUSR2, User defined signal 2.
    Thread 2 previously stopped with signal SIGUSR1, User defined signal 1.
  Continuing thread 1 (the current thread) with specified signal will
  still deliver the signals noted above to their respective threads.
  Continue anyway? (y or n)

All these scenarios are covered by the new tests.

Tested on x86_64 Fedora 20, native and gdbserver.

Pedro Alves c933f875f4 Put the inferior's terminal settings in effect while running (fg) infcalls 
The "call" and "print" commands presently always run synchronously, in
the foreground, but GDB currently forgets to put the inferior's
terminal settings into effect while running them, on async-capable
targets, resulting in:

 (gdb) print func ()
 hello world

 Program received signal SIGTTOU, Stopped (tty output).
 0x000000373bceb8d0 in __libc_tcdrain (fd=1) at ../sysdeps/unix/sysv/linux/tcdrain.c:29
 29          return INLINE_SYSCALL (ioctl, 3, fd, TCSBRK, 1);
 The program being debugged was signaled while in a function called from GDB.
 GDB remains in the frame where the signal was received.
 To change this behavior use "set unwindonsignal on".
 Evaluation of the expression containing the function
 (func) will be abandoned.
 When the function is done executing, GDB will silently stop.
 (gdb)

That's because target_terminal_inferior skips actually doing anything
if running in the background, and, nothing is setting sync_execution
while running infcalls:

 void
 target_terminal_inferior (void)
 {
   /* A background resume (``run&'') should leave GDB in control of the
      terminal.  Use target_can_async_p, not target_is_async_p, since at
      this point the target is not async yet.  However, if sync_execution
      is not set, we know it will become async prior to resume.  */
   if (target_can_async_p () && !sync_execution)
     return;

This would best be all cleaned up by making GDB not even call
target_terminal_inferior and try to pass the terminal to the inferior
if running in the background, but that's a more invasive fix that is
better done post-7.8.

This was originally caught by a patch later in this series that makes
catch_command_errors use exception_print instead of
print_any_exception.  Note that print_flush calls serial_drain_output
while print_any_exception doesnt't have that bit.  And,
gdb.gdb/python-selftest.exp does:

 gdb_test "call catch_command_errors(execute_command, \"python print 5\", 0, RETURN_MASK_ALL)" \
   "Python not initialized.* = 0"

which without this fix results in SIGTTOU...

Yao Qi b67a2c6fd4 Associate dummy_frame with ptid 
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field).  With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.

Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode.  The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.

Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2.  Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache.  Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong.  Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:

FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1

With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames.  Two fails above are fixed.

Regression tested on x86_64-linux, both native and gdbserver.

The issue is that when running an infcall, the thread is no longer
marked as running, so run_inferior_call is not calling
wait_for_inferior anymore.

Fix this by doing what the comment actually says we do:

  "Do here what `proceed' itself does in sync mode."

And proceed doesn't check whether the target is running.

I notice this is broken in case of the early return in proceed, but we
were broken before in that case anyway, because run_inferior_call will
think the call actually ran.  Seems like we should make proceed have a
boolean return, and go through all callers making use of it, if
necessary.

But for now, just fix the regression.

Tested on x86_64 Fedora 20.

Pedro Alves 45741a9c32 Add new infrun.h header. 
Move infrun.c declarations out of inferior.h to a new infrun.h file.

Tested by building on:

 i686-w64-mingw32, enable-targets=all
 x86_64-linux, enable-targets=all
 i586-pc-msdosdjgpp

And also grepped the whole tree for each symbol moved to find where
infrun.h might be necessary.

 (gdb) FAIL: gdb.base/dprintf.exp: 1st dprintf, call

The problem is that GDB gave the prompt back to the user too early.

This happens when calling functions while handling an event that
doesn't cause a user visible stop.  dprintf with "set dprintf-style
gdb" is one such case.  This patch adds a test case that has a
breakpoint with a condition that calls a function that returns false,
so that regression testing isn't dependent on the implementation of
dprintf.

The problem happens because run_inferior_call causes GDB to forget
that it is running in sync_execution mode, so any event that runs an
inferior call causes fetch_inferior_event to display the prompt, even
if the event should not result in a user visible stop (that is, gdb
resumes the inferior and waits for the next event).

This patch fixes the issue by noticing when GDB was in sync_execution
mode in run_inferior_call, and taking care to restore this state
afterward.

Tom Tromey efd66ac669 change minsym representation 
In a later patch we're going to change the minimal symbol address
calculation to apply section offsets at the point of use.  To make it
simpler to catch potential problem spots, this patch changes the
representation of minimal symbols and introduces new
minimal-symbol-specific variants of the various accessors.  This is
necessary because it would be excessively ambitious to try to convert
all the symbol types at once.

The core of this change is just renaming a field in minimal_symbol;
the rest is just a fairly mechanical rewording.

Joel Brobecker 40bc484cc3 [Ada/funcalls] do not coerce fat pointers on the stack 
When one of the parameter values in a subprogram calls is an array
whose value does not come from inferior memory, the debugger first
copies the array value in inferior memory.  Up to now, the memory
used to hold that copy was taken from the stack (just below the SP),
but this is causing problems on SPARC v9.

So the immediate fix is to follow what C does with arrays and strings,
which is allocate memory on the heap.

gdb/ChangeLog:

        * ada-lang.c: #include "value.h".
        (ensure_lval): Delete advance declaration.  Remove gdbarch and sp
        arguments.  Implement using value_allocate_space_in_inferior
        instead of allocating memory from the stack.
        (make_array_descriptor): Remove gdbarch and sp parameters.  Update
        calls to ensure_lval.
        (ada_convert_actual): Remove gdbarch and sp parameters.  Update
        calls to make_array_descriptor and ensure_lval.
        * ada-lang.h (ada_convert_actual): Update declaration.
        * infcall.c (value_arg_coerce): Update call to ada_convert_actual.
