Author: Pedro Alves <palves@redhat.com>
Branch: gdb-7.11-branch
Commit: 136613ef0c6850427317e57be1b644080ff6decb

Fix PR gdb/19828: gdb -p <process from a container>: internal error

When GDB attaches to a process, it looks at the /proc/PID/task/ dir
for all clone threads of that process, and attaches to each of them.

Usually, if there is more than one clone thread, it means the program
is multi threaded and linked with pthreads.  Thus when GDB soon after
attaching finds and loads a libthread_db matching the process, it'll
add a thread to the thread list for each of the initially found
lower-level LWPs.

If, however, GDB fails to find/load a matching libthread_db, nothing
is adding the LWPs to the thread list.  And because of that, "detach"
hits an internal error:

  (gdb) PASS: gdb.threads/clone-attach-detach.exp: fg attach 1: attach

Tested on x86-64 Fedora 23.  Also confirmed the test passes against
gdbserver with "maint set target-non-stop".

Unfortunately, making GDB add LWPs to the thread list sooner exposes
inefficiencies that in turn result in
gdb.threads/attach-many-short-lived-threads.exp timing out frequently.
Since that testcase is really a contrived use case designed to stress
some aspects of attach/detach and thread listing, not really
representative of real programs, this commit disables the test.

Make gdb/linux-nat.c consider a waitstatus pending on the infrun side

Working on the fix for gdb/19828, I saw
gdb.threads/attach-many-short-lived-threads.exp fail once in an
unusual way.  Unfortunately I didn't keep debug logs, but it's an
issue similar to what's been fixed in remote.c a while ago --
linux-nat.c was not fetching the pending status from the right place.

gdb/ChangeLog:
2016-05-25  Pedro Alves  <palves@redhat.com>

	PR gdb/19828
	* linux-nat.c (get_pending_status): If the thread reported the
	event to the core and it's pending, use the pending status signal
	number.

Branch: gdb-7.11-branch
Commit: b5f0db46b3057bcb64243e7da0943717abd6459b

Fix -exec-run not running asynchronously with mi-async on (PR gdb/18077)

When doing -exec-run on a freshly started GDB, the only target on the
target stack at the time the dummy one.  When mi_async_p is called to
know whether the run should be async, it queries whether the current
target (dummy) supports async, and the answer is no.  The fix is to make
the code query the target that will be used for the run, which is not
necessarily the current target.

No regressions in the gdb.mi directory using the unix, native-gdbserver
and native-extended-gdbserver boards.  The test doesn't pass when
forcing maint set target-async off, obviously, since it makes mi-async
have no effect.  It doesn't seem like other tests are checking for that
eventuality, so I didn't in the new test.

gdb/ChangeLog:

	* mi/mi-main.c (run_one_inferior): Use run target to determine
	whether to run async or not.
	(mi_cmd_exec_run): Likewise.

before output, even.

Workaround gdbserver<7.7 for setfs

With current FSF GDB HEAD and old FSF gdbserver I expected I could do:
	gdb -ex 'file target:/root/redhat/threadit' -ex 'target remote :1234'
(supplying that unsupported qXfer:exec-file:read by "file")
But that does not work because:
	Sending packet: $vFile:setfs:0#bf...Packet received: OK
	Packet vFile:setfs (hostio-setfs) is supported
	...
	Sending packet: $vFile:setfs:104#24...Packet received: OK
	"target:/root/redhat/threadit": could not open as an executable file: Invalid argument

GDB documentation says:
	The valid responses to Host I/O packets are:
	An empty response indicates that this operation is not recognized.

This "empty response" vs. "OK" was a bug in gdbserver < 7.7.  It was fixed by:

Commit: da611eed9a74de742e9436b6fdd92041b6e9bbf1

MIPS/Linux: Also recognize TRAP_BRKPT and TRAP_HWBKPT

This makes the MIPS Linux backends recognize TRAP_BRKPT and
TRAP_HWBKPT in siginfo.si_code in addition to SI_KERNEL, since Linux
4.6 now reports the finer-grained si_code values too.

Refs:
 https://sourceware.org/ml/gdb-patches/2016-02/msg00756.html
 https://sourceware.org/ml/gdb-patches/2016-04/msg00090.html

On kernels that report SI_KERNEL (<= 4.5), we'll enter the "ambiguous"
path of save_stop_reason:

	  if (GDB_ARCH_IS_TRAP_BRKPT (siginfo.si_code)
	      && GDB_ARCH_IS_TRAP_HWBKPT (siginfo.si_code))
	    {
	      /* The si_code is ambiguous on this arch -- check debug
		 registers.  */
	      if (!check_stopped_by_watchpoint (lp))
		lp->stop_reason = TARGET_STOPPED_BY_SW_BREAKPOINT;
	    }

while on kernels that report the finer-grained si_code values (>= 4.6),
we'll enter the corresponding branches:

	  else if (GDB_ARCH_IS_TRAP_BRKPT (siginfo.si_code))
	    {
	    }
	  else if (GDB_ARCH_IS_TRAP_HWBKPT (siginfo.si_code))

*** TEST RESULTS FOR COMMIT 619f36aa006c4263ec17b1d2a73613f840042c16 ***

Author: Pedro Alves <palves@redhat.com>
Branch: gdb-7.11-branch
Commit: 619f36aa006c4263ec17b1d2a73613f840042c16

Handle MIPS Linux SIGTRAP siginfo.si_code values

This unbreaks pending/delayed breakpoints handling, as well as
hardware watchpoints, on MIPS.

Ref: https://sourceware.org/ml/gdb-patches/2016-02/msg00681.html

The MIPS kernel reports SI_KERNEL for all kernel generated traps,
instead of TRAP_BRKPT / TRAP_HWBKPT, but GDB isn't aware of this.

Basically, this commit:

- Folds watchpoints logic into check_stopped_by_breakpoint, and
  renames it to save_stop_reason.

- Adds GDB_ARCH_IS_TRAP_HWBKPT.

- Makes MIPS set both GDB_ARCH_IS_TRAP_BRPT and
  GDB_ARCH_IS_TRAP_HWBKPT to SI_KERNEL.  In save_stop_reason, we
  handle the case of the same si_code returning true for both
  TRAP_BRPT and TRAP_HWBKPT by looking at what the debug registers
  say.

Tested on x86-64 Fedora 20, native and gdbserver.

Branch: gdb-7.11-branch
Commit: 6b9ef0d488c556339aea7b095ef7a9b6bf6b1af1

Fix PR remote/19840: gdb crashes on reverse-stepi

Reverse debugging against a remote target that does reverse debugging
itself (with the bs/bc packets) always trips on:

 (gdb) target remote localhost:...
 (gdb) reverse-stepi
 ../../gdb/target.c:602: internal-error: default_execution_direction: to_execution_direction must be implemented for reverse async

I missed adding a to_execution_direction method to remote.c in commit
3223143295b5 (Adds target_execution_direction to make record targets
support async mode), GDB 7.4 time.  Later, GDB 7.8 switched to
target-async on by default, making the regression user-visible by
default too.

Fix is simply to add the missing to_execution_direction implementation
to target remote.

Tested by Andi Kleen against Simics.

Author: Yichao Yu <yyc1992@gmail.com>

Commit: cd64cabb8c66a5565fc33bf66a07c08bc767e413

Fix PR gdb/19858: GDB doesn't register the JIT libraries on attach

Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html

GDB currently fails to fetch the list of already-registered JIT
modules on attach.

Nothing is calling jit_inferior_init, which is what is responsible for
walking the JIT object list at init time.

Despite the misleading naming, jit_inferior_created_hook ->
jit_inferior_init is only called when the inferior execs.

This regressed with the fix for PR gdb/13431 (03bef283c2d3):
 https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which
removed the inferior_created (jit_inferior_created_observer)
observer.

Adding an inferior_created observer back fixes the issue.

In turn, this exposes a bug in jit_breakpoint_re_set_internal as well,
which is returning the wrong result when we already have the
breakpoint at the right address.

gdb/ChangeLog:
2016-03-31  Yichao Yu  <yyc1992@gmail.com>

	PR gdb/19858
	* jit.c (jit_breakpoint_re_set_internal): Return 0 if we already
	got the breakpoint at the right address.
	(jit_inferior_created): New function.
	(_initialize_jit): Install jit_inferior_created as
	inferior_created observer.

btrace: fix PR gdb/19829

This is a backport of

33b4777ca1b7 btrace, frame: fix crash in get_frame_type
a038fa3e14a4 stack: check frame_unwind_caller_id
2f3ef606b912 frame: add skip_tailcall_frames

In skip_artificial_frames we repeatedly call get_prev_frame_always until we get
a non-inline and non-tailcall frame assuming that there must be such a frame
eventually.

For record targets, however, we may have a frame chain that consists only of
artificial frames.  This leads to a crash in get_frame_type when dereferencing a
NULL frame pointer.

Change skip_artificial_frames and skip_tailcall_frames to return NULL in such a
case and modify each caller to cope with a NULL return.

In frame_unwind_caller_pc and frame_unwind_caller_arch, we simply assert that
the returned value is not NULL.  Their caller was supposed to check
frame_unwind_caller_id before calling those functions.

In other cases, we thrown an error.

In infcmd further move the skip_tailcall_frames call to the forward-stepping
case since we don't need a frame for reverse execution and we don't want to fail
because of that.  Reverse-finish does make sense for a tailcall frame.

Branch: gdb-7.11-branch
Commit: e993d610a980ea8df9200f158bfae69308c2138d

PR remote/19496, internal err forking-threads-plus-bkpt

This patch fixes an internal error that occurs in
gdb.threads/forking-threads-plus-breakpoint.exp:

/blah/binutils-gdb/gdb/target.c:2723: internal-error: Can't determine the
current address space of thread Thread 3170.3170

In default_thread_address_space, find_inferior_ptid couldn't find 3170.3170
because it had been overwritten in inferior_appeared, called as follows:

inferior_appeared
  remote_add_inferior
    remote_notice_new_inferior
      remote_update_thread_list

The cause of the problem was the following sequence of events:

* GDB knows only about the main thread

* the first fork event is reported to GDB, saved as pending_event

* qXfer:threads:read gets the threads from the remote.
  remove_new_fork_children id's the fork child from the pending event
  and removes it from the list reported to GDB.  All the rest of the
  threads, including the fork parent, are added to the GDB thread list.

* GDB stops all the threads.  All the stop events are pushed onto the
  stop reply queue behind the pending fork event.  The fork waitstatus
  is saved in the fork parent thread's pending status field
  thread_info.suspend.

* remote_wait_ns calls queued_stop_reply and process_stop_reply to
  remove the fork event from the front of the stop reply queue and save
  event information in the thread_info structure for the fork parent
  thread.  Unfortunately, none of the information saved in this way is
  the fork-specific information.

* A subsequent qXfer:threads:read packet gets the thread list including
  the fork parent and fork child.  remove_new_fork_children checks the
  thread list to see if there is a fork parent, doesn't find one, checks
  the stop reply queue for a pending fork event, doesn't find one, and
  allows the fork child thread to be reported to GDB before the fork
  event has been handled.  remote_update_thread_list calls
  remote_notice_new_thread and overwrites the current (main) thread in
  inferior_appeared.

So the fork event has been reported out of target_wait but it was left
pending on the infrun side (infrun.c:save_waitstatus).  IOW, the fork
event hasn't been processed by handle_inferior_event yet, so it hasn't
made it to tp->pending_follow yet.

The fix is to check thread_info.suspend along with the
thread_info.pending_follow in remote.c:remove_new_fork_children, to
prevent premature reporting of the fork child thread creation.

gdb/ChangeLog:

	PR remote/19496
	* remote.c (remove_new_fork_children): Check for pending
	fork status in thread_info.suspend.

gdb/testsuite/ChangeLog:

	PR remote/19496

These issues get fixed (or removed if no longer applicable) by attached patch.

It is based on Googled:
	http://www.cs.rpi.edu/~szymansk/OOF90/bugs.html#5
	When a pointer is declared its status is undefined, and cannot be
	safely queried with the associated intrinsic.
	-> nullify(VARNAME)
+
	https://software.intel.com/en-us/forums/intel-fortran-compiler-for-linux-and-mac-os-x/topic/268786
	ALLOCATE is not supposed to initialize the array.
	-> Remove checks like an initial print is: \\( *0, *0, *0...\\)

These regressions remain:
	-PASS: gdb.fortran/library-module.exp: print var_i in lib
	+FAIL: gdb.fortran/library-module.exp: print var_i in lib
	-PASS: gdb.fortran/library-module.exp: print var_i in main
	+FAIL: gdb.fortran/library-module.exp: print var_i in main
I believe it is more a GDB bug (in a code contributed by me), filed:
	gdb.fortran/library-module.exp false regression on GCC upgrade

*** TEST RESULTS FOR COMMIT 83d9e733abe9cc0553f899064a955a6255550ade ***

Author: Yao Qi <yao.qi@linaro.org>
Branch: gdb-7.11-branch
Commit: 83d9e733abe9cc0553f899064a955a6255550ade

Clear *VAL in regcache_raw_read_unsigned

We have function regcache_raw_read_unsigned defined in both GDB and
GDBserver, so that it is used in common like this,

  ULONGEST value;
  status = regcache_raw_read_unsigned (regcache, regnum, &value);

'value' is correctly set in GDB side, but may not be correctly set
in GDBserver, because &value is passed in regcache_raw_read_unsigned
but collect_register may only set part of the whole variable.  In my
test, I see the top half of 'value' is garbage.  This patch fixes this
problem by clearing *VAL before calling collect_register.

gdb/gdbserver:

2016-02-10  Yao Qi  <yao.qi@linaro.org>

	* regcache.c (regcache_raw_read_unsigned): Clear *VAL.
