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...

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).

[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.

Add NEWS entry for fast tracepoint support on aarch64-linux

Here is a NEWS entry for this series:

gdb/ChangeLog:

* NEWS: Mention support for fast tracepoints on aarch64-linux.

Add a test case for fast tracepoints' locking mechanism

When installing a fast tracepoint, we create a jump pad with a
spin-lock.  This way, only one thread can collect a given tracepoint at
any time.  This test case checks that this lock actually works as
expected.

This test works by creating a function which overrides the in-process
agent library's gdb_collect function.  On start up, GDBserver will ask
GDB with the 'qSymbol' packet about symbols present in the inferior.
GDB will reply with the gdb_agent_gdb_collect function from the test
case instead of the one from the agent.

gdb/testsuite/ChangeLog:

* gdb.trace/ftrace-lock.c: New file.
* gdb.trace/ftrace-lock.exp: New file.

Add a gdb.trace test for instruction relocation

This test case makes sure that relocating PC relative instructions does
not change their behaviors.  All PC relative AArch64 instructions are
covered.  While call and jump (32 bit relative) instructions are covered
on x86.

The test case creates a static array of function pointers for each
supported architecture.  Each function in this array tests a specific
instruction using inline assembly.  They all need to contain a symbol in
the form of 'set_point\[0-9\]+' and finish by either calling pass or
fail.  The number of 'set_pointN' needs to go from 0 to
(ARRAY_SIZE - 1).

The test will:
- look up the number of function pointers in the static array.
- set fast tracepoints on each 'set_point\[0-9\]+' symbol, one in each
  functions from 0 to (ARRAY_SIZE - 1).
- run the trace experiment and make sure the pass function is called for
  every function.

Implement target_emit_ops

This patch implements compiling agent expressions to native code for
AArch64.  This allows us to compile conditions set on fast tracepoints.

The compiled function has the following prologue:

High *------------------------------------------------------*
     | LR                                                   |
     | FP                                                   | <- FP
     | x1  (ULONGEST *value)                                |
     | x0  (unsigned char *regs)                            |
Low  *------------------------------------------------------*

We save the function's argument on the stack as well as the return
address and the frame pointer.  We then set the current frame pointer to
point to the previous one.

The generated code for the expression will freely update the stack
pointer so we use the frame pointer to refer to `*value' and `*regs'.
`*value' needs to be accessed in the epilogue of the function, in order
to set it to whatever is on top of the stack.  `*regs' needs to be passed
down to the `gdb_agent_get_raw_reg' function with the `reg' operation.

Add support for fast tracepoints

This patch adds support for fast tracepoints for aarch64-linux.  With this
implementation, a tracepoint can only be placed in a +/- 128MB range of
the jump pad.  This is due to the unconditional branch instruction
being limited to a (26 bit << 2) offset from the current PC.

Three target operations are implemented:

- target_install_fast_tracepoint_jump_pad

Building the jump pad the biggest change of this patch.  We need to add
functions to emit all instructions needed to save and restore the
current state when the tracepoint is hit.  As well as implementing a
lock and creating a collecting_t object identifying the current thread.

Steps performed by the jump pad:

  * Save the current state on the stack.
  * Push a collecting_t object on the stack.  We read the special
  tpidr_el0 system register to get the thread ID.
  * Spin-lock on the shared memory location of all tracing threads.  We
  write the address of our collecting_t object there once we have the
  lock.
  * Call gdb_collect.
  * Release the lock.
  * Restore the state.

  * Execute the replaced instruction which will have been relocated.
  * Jump back to the program.

- target_get_thread_area

As implemented in ps_get_thread_area, target_get_thread_area uses ptrace
to fetch the NT_ARM_TLS register.  At the architecture level, NT_ARM_TLS
represents the tpidr_el0 system register.

So this ptrace call (if lwpid is the current thread):
~~~
ptrace (PTRACE_GETREGSET, lwpid, NT_ARM_TLS, &iovec);
~~~

Is equivalent to the following instruction:
~~~
msr x0, tpidr_el0
~~~

This instruction is used when creating the collecting_t object that
GDBserver can read to know if a given thread is currently tracing.

So target_get_thread_area must get the same thread IDs as what the jump
pad writes into its collecting_t object.

- target_get_min_fast_tracepoint_insn_len

This just returns 4.

Make aarch64_decode_adrp handle both ADR and ADRP instructions

We will need to decode both ADR and ADRP instructions in GDBserver.

to decode the ADRP instruction.

gdb/ChangeLog:

'aarch64_':

 - aarch64_decode_adrp
 - aarch64_decode_b
 - aarch64_decode_cb
 - aarch64_decode_tb

We will need them to implement fast tracepoints in GDBserver.

For consistency, this patch also adds the 'aarch64_' prefix to static
decoding functions that do not need to be shared right now.

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 63e43d3aedb8b1112899c2d0ad74cbbee687e5d6
    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.

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

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.

gdb/
* record-btrace.c (record_btrace_resume): Honour scheduler-locking.

testsuite/
* gdb.btrace/multi-thread-step.exp: Test scheduler-locking on, step,
and replay.

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.

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.

target, record: add PTID argument to to_record_is_replaying

The to_record_is_replaying target method is used to query record targets if

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 PTID argument.

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.

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

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.

gdb/
* record-btrace.c (record_btrace_maybe_mark_async_event): New.
(record_btrace_wait): Call record_btrace_maybe_mark_async_event.

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.

gdb/
* record-btrace.c (get_thread_current_frame): New.
(record_btrace_start_replaying): Call get_thread_current_frame.

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".

gdb/
* record-btrace.c (record_btrace_resume_thread): A move request
overwrites a previous move request.
(record_btrace_find_resume_thread): Removed.
(record_btrace_resume): Resume all requested threads.

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.

to announce that.  Fix it.

NO_HISTORY if a step brings us to the end of the execution history.

btrace: move breakpoint checking into stepping functions

Breakpoints are only checked for BTHR_CONT and BTHR_RCONT stepping requests.
A BTHR_STEP and BTHR_RSTEP request will always report stopped without reason.
Since breakpoints are reported correctly, I assume infrun is handling this.

Move the breakpoint check into the btrace single stepping functions.  This
will cause us to report breakpoint hits now also for single-step requests.

One thing to notice is that

  - when executing forwards, the breakpoint is checked before 'executing'
    the instruction, i.e. before moving the PC to the next instruction.

  - when executing backwards,  the breakpoint is checked after 'executing'
    the instruction, i.e. after moving the PC to the preceding instruction
    in the recorded execution.

There is code in infrun (see, for example proceed and adjust_pc_after_break)
that handles this and also depends on this behaviour.

gdb/
* record-btrace.c (record_btrace_step_thread): Move breakpoint check
to ...
(record_btrace_single_step_forward): ... here and
(record_btrace_single_step_backward): ... here.

btrace: split record_btrace_step_thread

The code for BTHR_STEP and BTHR_CONT is fairly similar.  Extract the common
parts into a new function record_btrace_single_step_forward.  The function
returns TARGET_WAITKIND_SPURIOUS to indicate that the single-step completed
without triggering a trap.

[Ada] Enhance type printing for arrays with variable-sized elements

This change is relevant only for standard DWARF (as opposed to the GNAT
encodings extensions): at the time of writing it only makes a difference
with GCC patches that are to be integrated: see the patch series
submission at
<https://gcc.gnu.org/ml/gcc-patches/2015-07/msg01353.html>.

Given the following Ada declarations:

   subtype Small_Int is Natural range 0 .. 100;
   type R_Type (L : Small_Int := 0) is record
      S : String (1 .. L);
   end record;
   type A_Type is array (Natural range <>) of R_Type;

   A : A_Type := (1 => (L => 0, S => ""),
                  2 => (L => 2, S => "ab"));

Before this change, we would get the following GDB session:

    (gdb) ptype a
    type = array (1 .. 2) of foo.r_type <packed: 838-bit elements>

This is wrong: "a" is not a packed array.  This output comes from the
fact that, because R_Type has a dynamic size (with a maximum), the
compiler has to describe in the debugging information the size allocated
for each array element (i.e. the stride, in DWARF parlance: see
DW_AT_byte_stride).  Ada type printing currently assumes that arrays
with a stride are packed, hence the above output.

In practice, GNAT never performs bit-packing for arrays that contain
variable-sized elements.  Leveraging this fact, this patch enhances type
printing so that ptype does not pretend that arrays are packed when they
have a stride and they contain dynamic elements.  After this change, we
get the following expected output:

    (gdb) ptype a
    type = array (1 .. 2) of foo.r_type

gdb/doc: revert previous vforkdone change

The previous manual change was wrong.  The vfork parent thread ID

This is already how the parent is reported in the vfork/fork events,
and is actually what the fix made gdbserver do.  Following the
documentation change, the event would have been reported like this

PR remote/18965
* gdb.texinfo (Stop Reply Packets): Revert previous change to
the vforkdone description.

[AArch64] Use debug_printf instead of fprintf_unfiltered

GDBserver uses debug_printf to print debugging output.  This patch makes
GDB use this too so we can share some of this code with GDBserver later.
