04c4fe8c59 btrace: fix void return
record_btrace_resume returns the void return from the to_resume method of the
target beneath.  Split this into calling to_resume and return.

cbd641edf3 parse load_offset (bias) of restore command as long
Following failures are noticed for avr-gdb. This may be the case
for targets like AVR which has integer_to_address hook defined.

FAIL: gdb.base/dump.exp: struct copy, srec; value restored ok
FAIL: gdb.base/dump.exp: struct copy, ihex; value restored ok
FAIL: gdb.base/dump.exp: struct copy, tekhex; value restored ok

These tests are failed because load_offset(bias) of restore command
parsed as address.

command: restore filename [binary] bias start end

Except binary, other BFDs have a built-in location; gdb restores content
at offset 'bias' from that location. So, 'bias' of 'restore' command should
be parsed as address only when the file is binary.

Below patch changes gdb to parse 'bias' as long if the file is not binary.

ede5f15146 gdbarch.h: Change gdbarch_info::tdep_info's type to void *
As reported by Ulrich here:

  https://sourceware.org/ml/gdb-patches/2015-09/msg00604.html

The system compiler (gcc 4.1) in Centos 5 doesn't like that we cast to a
pointer to a type that doesn't exist.  I see no real value in using this
kind iof construct over just using void *.  So this patch changes the
tdep_info field to void * and removes the casts.  Even in C++, we
should not need an explicit cast when assigning to a void *.

gdb/ChangeLog:

	* gdbarch.sh (struct gdbarch_info): Change tdep_info's type to void *.
	* gdbarch.h: Regenerate.
	* i386-tdep.c (i386_gdbarch_init): Remove cast to
	struct gdbarch_tdep_info *.

aca20ec473 infcmd.c: Don't attempt to record a NULL value after a finish command.
Architectures which use RETURN_VALUE_STRUCT_CONVENTION will have a
NULL return value after executing a finish command.  See get_return_value()
in infcmd.c.

This patch avoids an eventual SIGSEV (caused by attempting to
derefrence a NULL pointer) by adding a suitable test to
finish_command_fsm_should_stop().

I encountered this problem while testing msp430:

(gdb) PASS: gdb.base/structs.exp: zed L<n> for finish; return 1 structs-tc
finish
Run till exit from #0  fun1 () at /ironwood1/sourceware-git/msp430-elf/../binutils-gdb/gdb/testsuite/gdb.base/structs.c:125
ERROR: Process no longer exists

    	* infcmd.c (finish_command_fsm_should_stop): Don't attempt to
    	record a NULL value.

3b1ad7d510 msp430: Fix bug regarding large memory model inferior function call arguments.
This change causes reference, struct, and union arguments to be treated
the same as pointer arguments when determining the size of the value to
place into a register.

The case for doing this for reference arguments is obvious.

The msp430 ABI specifies that struct and union arguments are passed by
reference.  This is why they're treated in the same manner as pointer
and reference arguments when computing the size of the value to place
into a register.

In my testing using this multilib...

msp430-sim/-msim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either

... I find that the the following failures, 125 in all, are fixed by this
patch.

9a3c826307 Add some more casts (1/2)
Note: I needed to split this patch in two, otherwise it's too big for
the mailing list.

This patch adds explicit casts to situations where a void pointer is
assigned to a pointer to the "real" type.  Building in C++ mode requires
those assignments to use an explicit cast.  This includes, for example:

 - callback arguments (cleanups, comparison functions, ...)
 - data attached to some object (objfile, program space, etc) in the form
   of a void pointer
 - "user data" passed to some function

This patch comes from the commit "(mostly) auto-generated patch to insert
casts needed for C++", taken from Pedro's C++ branch.

Only files built on x86 with --enable-targets=all are modified, so the
native files for other arches will need to be dealt with separately.

I built-tested this with --enable-targets=all and reg-tested.  To my
surprise, a test case (selftest.exp) had to be adjusted.

Here's the ChangeLog entry.  Again, this was relatively quick to make
despite the length, thanks to David Malcom's script, although I don't
believe it's very useful information in that particular case...

224c3ddb89 Add casts to memory allocation related calls
Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

e6c2c623f7 [Ada] Fix handling of array renamings
Compilers can materialize renamings of arrays (or of accesses to arrays)
in Ada into variables whose types are references to the actual array
types.  Before this change, trying to use such an array renaming yielded
an error in GDB:

    (gdb) print my_array(1)
    cannot subscript or call a record
    (gdb) print my_array_ptr(1)
    cannot subscript or call something of type `(null)'

This behavior comes from bad handling for array renamings, in particular
the OP_FUNCALL expression operator handling from ada-lang.c
(ada_evaluate_subexp): in one place we turn the reference into a
pointer, but the code that follows expect the value to be an array.

This patch fixes how we handle references in call/subscript evaluation
so that we turn these references into the actual array values instead of
pointers to them.

gdb/ChangeLog:

	* ada-lang.c (ada_evaluate_subexp) <OP_FUNCALL>: When the input
	value is a reference, actually dereference it in order to get
	the underlying value.

gdb/testsuite/ChangeLog:

	* gdb.ada/array_ptr_renaming.exp: New testcase.
	* gdb.ada/array_ptr_renaming/foo.adb: New file.

7d1c9c9b4c crash printing non-local variable from nested subprogram
We have noticed that GDB would sometimes crash trying to print
from a nested function the value of a variable declared in an
enclosing scope. This appears to be target dependent, although
that correlation might only be fortuitious.  We noticed the issue
on x86_64-darwin, x86-vxworks6 and x86-solaris.  The investigation
was done on Darwin.

This is a new feature that was introduced by:

    commit 63e43d3aed
    Date:   Thu Feb 5 17:00:06 2015 +0100
    DWARF: handle non-local references in nested functions

We can reproduce the problem with one of the testcases that was
added with the patch (gdb.base/nested-subp1.exp), where we have...

    18 int
    19 foo (int i1)
    20 {
    21   int
    22   nested (int i2)
    23   {
    [...]
    27     return i1 * i2; /* STOP */
    28   }

...  After building the example program, and running until line 27,
try printing the value of "i1":

    % gdb gdb.base/nested-subp1
    (gdb) break foo.c:27
    (gdb) run
    Breakpoint 1, nested (i2=2) at /[...]/nested-subp1.c:27
    27          return i1 * i2; /* STOP */
    (gdb) p i1
    [1]    73090 segmentation fault  ../gdb -q gdb.base/nested-subp1

Ooops!

What happens is that, because the reference is non-local, we are trying
to follow the function's static link, which does...

    /* If we don't know how to compute FRAME's base address, don't give up:
       maybe the frame we are looking for is upper in the stace frame.  */
    if (framefunc != NULL
        && SYMBOL_BLOCK_OPS (framefunc)->get_frame_base != NULL
        && (SYMBOL_BLOCK_OPS (framefunc)->get_frame_base (framefunc, frame)
            == upper_frame_base))

... or, in other words, calls the get_frame_base "method" of
framefunc's struct symbol_block_ops data. This resolves to
the block_op_get_frame_base function.

Looking at the function's implementation, we see:

  struct dwarf2_locexpr_baton *dlbaton;
  [...]
  dlbaton = SYMBOL_LOCATION_BATON (framefunc);
  [...]
  result = dwarf2_evaluate_loc_desc (type, frame, start, length,
                                     dlbaton->per_cu);
                                     ^^^^^^^^^^^^^^^

Printing dlbaton->per_cu gives a value that seems fairly bogus for
a memory address (0x60). Because of it, dwarf2_evaluate_loc_desc
then crashes trying to dereference it.

What's different on Darwin compared to Linux is that the function's
frame base is encoded using the following form:

        .byte   0x40    # uleb128 0x40; (DW_AT_frame_base)
        .byte   0x6     # uleb128 0x6; (DW_FORM_data4)

... and so dwarf2_symbol_mark_computed ends up creating
a SYMBOL_LOCATION_BATON as a struct dwarf2_loclist_baton:

  if (attr_form_is_section_offset (attr)
      /* .debug_loc{,.dwo} may not exist at all, or the offset may be outside
         the section.  If so, fall through to the complaint in the
         other branch.  */
      && DW_UNSND (attr) < dwarf2_section_size (objfile, section))
    {
      struct dwarf2_loclist_baton *baton;
      [...]
      SYMBOL_LOCATION_BATON (sym) = baton;

However, if you look more closely at block_op_get_frame_base's
implementation, you'll notice that the function extracts the
symbol's SYMBOL_LOCATION_BATON as a dwarf2_locexpr_baton
(a DWARF _expression_ rather than a _location list_).
That's why we end up decoding the DLBATON improperly, and thus
pass a random dlbaton->per_cu when calling dwarf2_evaluate_loc_desc.

This works on x86_64-linux, because we indeed have the frame base
described using a different form:

        .uleb128 0x40   # (DW_AT_frame_base)
        .uleb128 0x18   # (DW_FORM_exprloc)

This patch fixes the issue by doing what we do for most (if not all)
other such methods: providing one implementation each for loc-list,
and loc-expr. Both implementations are nearly identical, so perhaps
we might later want to improve this. But this patch first tries to
fix the crash first, leaving the design issue for later.

a0cc84cd15 aarch64 multi-arch (part 3): get thread area
With the kernle fix <http://lists.infradead.org/pipermail/linux-arm-kernel/2015-July/356511.html>,
aarch64 GDB is able to read the base of thread area of 32-bit arm
program through NT_ARM_TLS.

This patch is to teach both GDB and GDBserver to read the base of
thread area correctly in the multi-arch case.  A new function
aarch64_ps_get_thread_area is added, and is shared between GDB and
GDBserver.

With this patch applied, the following fails in multi-arch testing
(GDB is aarch64 but the test cases are arm) are fixed,

 -FAIL: gdb.threads/tls-nodebug.exp: thread local storage
 -FAIL: gdb.threads/tls-shared.exp: print thread local storage variable

d2939ba2b4 btrace: honour scheduler-locking for all-stop targets
In all-stop mode, record btrace maintains the old behaviour of an implicit
scheduler-locking on.

Now that we added a scheduler-locking mode to model this old behaviour, we
don't need the respective code in record btrace anymore.  Remove it.

For all-stop targets, step inferior_ptid and continue other threads matching
the argument ptid.  Assert that inferior_ptid matches the argument ptid.

This should make record btrace honour scheduler-locking.

f2665db5f2 infrun: scheduler-locking replay
Record targets behave as if scheduler-locking were on in replay mode.  Add a
new scheduler-locking option "replay" to make this implicit behaviour explicit.
It behaves like "on" in replay mode and like "off" in record mode.

By making the current behaviour a scheduler-locking option, we allow the user
to change it.  Since it is the current behaviour, this new option is also
the new default.

One caveat is that when resuming a thread that is at the end of its execution
history, record btrace implicitly stops replaying other threads and resumes
the entire process.  This is a convenience feature to not require the user
to explicitly move all other threads to the end of their execution histories
before being able to resume the process.

We mimick this behaviour with scheduler-locking replay and move it from
record-btrace into infrun.  With all-stop on top of non-stop, we can't do
this in record-btrace anymore.

Record full does not really support multi-threading and is therefore not
impacted.  If it were extended to support multi-threading, it would 'benefit'
from this change.  The good thing is that all record targets will behave the
same with respect to scheduler-locking.

I put the code for this into clear_proceed_status.  It also sends the
about_to_proceed notification.

	* NEWS: Announce new scheduler-locking mode.
	* infrun.c (schedlock_replay): New.

4d10e986f4 btrace: allow full memory and register access for non-replaying threads
The record btrace target does not allow accessing memory and storing registers
while replaying.  For multi-threaded applications, this prevents those
accesses also for threads that are at the end of their execution history as
long as at least one thread is replaying.

Change this to only check if the selected thread is replaying.  This allows
threads that are at the end of their execution history to read and write
memory and to store registers.

Also change the error message to reflect this change.

a52eab4808 target, record: add PTID argument to to_record_is_replaying
The to_record_is_replaying target method is used to query record targets if
they are replaying.  This is currently interpreted as "is any thread being
replayed".

Add a PTID argument and change the interpretation to "is any thread matching
PTID being replayed".

Change all users to pass minus_one_ptid to preserve the old meaning.

The record full target does not really support multi-threading and ignores
the PTID argument.

	* record-btrace.c (record_btrace_is_replaying): Add ptid argument.
	Update users to pass minus_one_ptid.

d1988021e3 infrun: switch to NO_HISTORY thread
A thread that runs out of its execution history is stopped.  We already set
stop_pc and call stop_waiting.  But we do not switch to the stopped thread.

In normal_stop, we call finish_thread_state_cleanup to set a thread's running
state.  In all-stop mode, we call it with minus_one_ptid; in non-stop mode, we
only call it for inferior_ptid.

If in non-stop mode normal_stop is called on behalf of a thread that is not
inferior_ptid, that other thread will still be reported as running.  If it is
actually stopped it can't be resumed again.

Record targets traditionally don't support non-stop and only resume
inferior_ptid.  So this has not been a problem, so far.

Switch to the eventing thread for NO_HISTORY events as preparation to support
non-stop for the record btrace target.

	* infrun.c (handle_inferior_event_1): Switch to the eventing thread
	in the TARKET_WAITKIND_NO_HISTORY case.

a6b5be76f9 btrace: async
The record btrace target runs synchronous with GDB.  That is, GDB steps
resumed threads in record btrace's to_wait method.  Without GDB calling
to_wait, nothing happens 'on the target'.

Check for further expected events in to_wait before reporting the current
event and mark record btrace's async event handler in async mode.

	* record-btrace.c (record_btrace_maybe_mark_async_event): New.

ec71cc2fc6 btrace: temporarily set inferior_ptid in record_btrace_start_replaying
Get_current_frame uses inferior_ptid.  In record_btrace_start_replaying,
we need to get the current frame of the argument thread.  So far, this
has always been inferior_ptid.  With non-stop, this is not guaranteed.

Temporarily set inferior_ptid to the ptid of the argument thread.

We already temporarily set the argument thread's executing flag to false.

Move both into a new function get_thread_current_frame that does the temporary
adjustments, calls get_current_frame, and restores the previous values.

	* record-btrace.c (get_thread_current_frame): New.

0ca912dfef btrace: resume all requested threads
The record targets are implicitly schedlocked.  They only step the current
thread and keep other threads where they are.

Change record btrace to step all requested threads in to_resume.

For maintenance and debugging, we keep the old behaviour when the target below
is not non-stop.  Enable with "maint set target-non-stop on".

	overwrites a previous move request.

e3cfc1c76d btrace: lock-step
Record btrace's to_wait method picks a single thread to step.  When passed
minus_one_ptid, it picks the current thread.  All other threads remain where
they are.

Change this to step all resumed threads together, one step at a time, until
the first thread reports an event.

We do delay reporting NO_HISTORY events until there are no other events to
report to prevent threads at the end of their execution history from starving
other threads.

We keep threads at the end of their execution history moving and replaying
until we announce their stop in to_wait.  This shouldn't really be user-visible
but its a detail worth mentioning.

Since record btrace's to_resume method also picks only a single thread to
resume, there shouldn't be a difference with the current all-stop.

With non-stop or all-stop on top of non-stop, we will see differences.  The
behaviour should be more natural as we're moving all threads.
