Fix missing-prototypes warnings in gnu-nat.c

A recent change (commit 3398af6aa352b0611bc9d66aed72080a876e42d4)
in gnu-nat.c causes the some missing-prototypes warnings,

A new macro ILL_RPC was added recently, which defines some external
functions.  However, they are not declared and GCC complains about this.

This patch is to add the declarations of these external function in

Fix "ERROR: no fileid for" in the testsuite.

If GDB has crashed then gdb_spawn_id still exists (although it does not work).
So my patch does not change anything.  And also currently it will leave the
stale gdbserver running anyway.

In general if gdb_spawn_id does not exist then send_gdb + gdb_expect just do
not make sense anyway.  So this patch just prevents the error in such case.

The killing of stale gdbserver could be improved multiple ways (also as
suggested by Pedro in the original thread) but that is IMO outside of the
scope of this patch.  Apparently if there is no good response from GDB then
gdb_finish() should try to call gdb_start just to kill that gdbserver, IIUC.

Explicitly mark vtables as code space

Ports for Hardvard architectures will typically have in their
pointer_to_address hook a check for TYPE_CODE_SPACE in their
"pointer_to_address" gdbarch method.  E.g., rl78's:

  /* Is it a code address?  */
  if (TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_FUNC
      || TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_METHOD

      || TYPE_LENGTH (type) == 4)
    return rl78_make_instruction_address (addr);
  else
    return rl78_make_data_address (addr);

The avr port is similar.

The vtable type is a struct type gdb itself bakes.  Being neither a
function, nor a method, and absent explicit flagging as residing in
code space, ends up being considered data.

This patch marks the type as code when it is created, on the theory
that this is needed for all Hardvard architectures.  I believe this
should make no difference on archs with flat address space.  Testing
on x86-64 GNU/Linux shows no changes.

One of the regressions is:

Note that the difference between these are the warnings regarding
linker symbols.  Aside from the warnings, the result is the same.
I.e.  gdb produces the correct answer despite the warnings.  The
reason for the other 8 failures is the same: the test harness is not
expecting these warnings.

I spent some time (a while ago) looking at the reason for these
warnings.  As I recall, we are now getting further along in the type
resolution process than we were without my patch.  I.e.  for the
example above, the code in question never got to the point where it
was looking for the specified linker symbol.  So it seems to me that,
at worst, my patch exposes some other problem, but is not directly the
cause of the problem.

H8/300: Fix gdb<->sim register mapping.

Currently, printing the H8/300 ccr register when debugging with the
sim is broken:

 (gdb) target sim
 ...
 (gdb) load
 ...
 (gdb) start
 ...
 Breakpoint 1, foo (i=0x0 <foo>) at main.c:4
 4       {
 (gdb) info registers ccr
 Register 13 is not available

'13' is the ccr pseudo-register.  This pseudo-register provides an
8-bit view into the raw ccr register (regno=8).

The problem is that the H8/300 port does not define a
register_sim_regno gdbarch hook, and thus when fetching the raw
register off of the sim, we end up in legacy_register_sim_regno trying
to figure out the sim register number for the raw CCR register:

 int
 legacy_register_sim_regno (struct gdbarch *gdbarch, int regnum)
 {
   /* Only makes sense to supply raw registers.  */
   gdb_assert (regnum >= 0 && regnum < gdbarch_num_regs (gdbarch));
   /* NOTE: cagney/2002-05-13: The old code did it this way and it is
      suspected that some GDB/SIM combinations may rely on this
      behavour.  The default should be one2one_register_sim_regno
      (below).  */
   if (gdbarch_register_name (gdbarch, regnum) != NULL
       && gdbarch_register_name (gdbarch, regnum)[0] != '\0')
     return regnum;
   else
     return LEGACY_SIM_REGNO_IGNORE;
 }

Because the raw ccr register does not have a name (so that it is
hidden from the user), that returns LEGACY_SIM_REGNO_IGNORE.  That
means that we never actually read the value of the raw ccr register.

Before the <unavailable> support, this must have meant that ccr was
_always_ read as 0...  At least, I'm not seeing how this ever worked.

The fix for that is adding a gdbarch_register_sim_regno hook that maps
all raw registers.  Looking at sim/h8300/sim-main.h, I believe the
sim's register numbers are compatible with gdb's, so no actual
convertion is necessary.

Yao Qi [Mon, 27 Jan 2014 12:35:33 +0000 (20:35 +0800)]
Return target_xfer_status in to_xfer_partial

This patch does the conversion of to_xfer_partial from

    LONGEST (*to_xfer_partial) (struct target_ops *ops,
enum target_object object, const char *annex,
gdb_byte *readbuf, const gdb_byte *writebuf,
ULONGEST offset, ULONGEST len);

to

    enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops,
enum target_object object, const char *annex,
gdb_byte *readbuf, const gdb_byte *writebuf,
ULONGEST offset, ULONGEST len, ULONGEST *xfered_len);

It changes to_xfer_partial return the transfer status and the transfered
length by *XFERED_LEN.  Generally, the return status has three stats,

 - TARGET_XFER_OK,
 - TARGET_XFER_EOF,
 - TARGET_XFER_E_XXXX,

See the comments to them in 'enum target_xfer_status'.  Note that
Pedro suggested not name TARGET_XFER_DONE, as it is confusing,
compared with "TARGET_XFER_OK".  We finally name it TARGET_XFER_EOF.

With this change, GDB core can handle unavailable data in a convenient
way.

The rationale behind this change was mentioned here
https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html

Consider an object/value like this:

  0          100      150        200           512
  DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III

where D is valid data, and xxx is unavailable data, and I is beyond
the end of the object (Invalid).  Currently, if we start the
xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes.
The xfer machinery then retries fetching [100,512), and gets back
TARGET_XFER_E_UNAVAILABLE.  That's sufficient when you're either
interested in either having the whole of the 512 bytes available,
or erroring out.  But, in this scenario, we're interested in
the data at [150,512).  The problem is that the last
TARGET_XFER_E_UNAVAILABLE gives us no indication where to
start the read next.  We'd need something like:

get me [0,512) >>>
     <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK

get me [100,512)  >>> (**1)
     <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE.

get me [150,512) >>>
     <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK.

get me [200,512) >>>
     <<< no more data, return TARGET_XFER_EOF.

This naturally implies pushing down the decision of whether
to return TARGET_XFER_E_UNAVAILABLE or something else
down to the target.  (Which kinds of leads back to tfile
itself reading from RO memory from file (though we could
export a function in exec.c for that that tfile delegates to,
instead of re-adding the old code).

Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to
check whether a status is an error or not, to stop using "status < 0".
This patch also eliminates the comparison between status and 0.

No target implementations to to_xfer_partial adapts this new
interface.  The interface still behaves as before.

Make sure we don't resume the stepped thread by accident.

Say:

<stopped at a breakpoint in thread 2>
(gdb) thread 3
(gdb) step

The above triggers the prepare_to_proceed/deferred_step_ptid process,
which switches back to thread 2, to step over its breakpoint before
getting back to thread 3 and "step" it.

If while stepping over the breakpoint in thread 2, a signal arrives,
and it is set to pass/nostop, we'll set a step-resume breakpoint at
the supposed signal-handler resume address, and call keep_going.  The
problem is that we were supposedly stepping thread 3, and that
keep_going delivers a signal to thread 2, and due to scheduler-locking
off, resumes everything else, _including_ thread 3, the thread we want
stepping.  This means that we lose control of thread 3 until the next
event, when we stop everything.  The end result for the user, is that
GDB lost control of the "step".

The test turns on infrun debug, does a stepi while a SIGCHLD is
pending, and checks whether the "random signal" paths in infrun.c are
taken.

On the software single-step variant above, those paths were not taken.

This is a test bug.

The Linux backend short-circuits reporting signals that are set to
pass/nostop/noprint.  But _only_ if the thread is _not_
single-stepping.  So on hardware-step targets, even though the signal
is set to pass/nostop/noprint by default, the thread is indeed told to
single-step, and so the core sees the signal.  On the other hand, on
software single-step architectures, the backend never actually gets a
single-step request (steps are emulated by setting a breakpoint at the
next pc, and then the target told to continue, not step).  So the
short-circuiting code triggers and the core doesn't see the signal.

The fix is to make the test be sure the target doesn't bypass
reporting the signal to the core.

Tested on x86_64 Fedora 17, both with and without a series that
implements software single-step for x86_64.

Yao Qi [Wed, 29 Jan 2014 03:48:40 +0000 (11:48 +0800)]
Return early in target_xfer_partial when LEN is zero.

Nowadays, argument LEN of to_xfer_partial can be zero in some cases,
and each implementation may do nothing and return zero, indicating
transfer is done.  That is fine.  However, when we change
to_xfer_partial to return target_xfer_status, we have to check every
return value of most of to_xfer_partial implementations, return
TARGET_XFER_DONE if return value is zero.

This patch simplifies this by checking LEN in target_xfer_partial, and
return 0 if LEN is zero.  Regression tested on x86_84-linux.  Is it
OK?
