e0d13cbd4b ctf.c: Fix int/enum implicit cast
This patch was taken directly from Pedro's branch.

Right now, SET_INT32_FIELD is used to set enum fields.  This works in C,
but not C++.  Therefore, define the new SET_ENUM_FIELD, which casts the
value to the right enum type.

gdb/ChangeLog:

	* ctf.c (SET_ENUM_FIELD): New macro.
	(ctf_read_status): Use it.
	(ctf_read_tp): Use it.

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).

8d7493201c Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort.  The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family.  This avoids adding an explicit cast, so
it keeps the code a bit more readable.  Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.

I only changed calls that were obviously allocating memory for one or
multiple "objects".  Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).

  - xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
  - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
  - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
  - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
  - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
  - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
  - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
  - alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
  - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)

Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.

I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files.  For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

510db0520b Remove workaround to libbabeltrace 1.1.0 issue
When GDB uses recent version of babeltrace, such as 1.2.x, we'll see
such error emitted from babeltrace library,

 (gdb) target ctf .../gdb/testsuite/gdb.trace/actions.ctf
 [error] Invalid CTF stream: content size is smaller than packet headers.
 [error] Stream index creation error.
 [error] Open file stream error.

The problem can be reproduce out of GDB too, using babeltrace,

 $ babeltrace ./fake-packet.ctf/
 [error] Invalid CTF stream: content size is smaller than packet headers.
 [error] Stream index creation error.
 [error] Open file stream error.

Recent babeltrace library becomes more strict on CTF, and complains
about one "faked packet" GDB adds, when saving trace data in ctf
format from GDB.  babeltrace 1.1.0 has a bug that it can't read trace
data smaller than a certain size (see https://bugs.lttng.org/issues/450).
We workaround it in GDB to append some meaningless data in a faked
packet to make sure trace file is large enough (see ctf.c:ctf_end).
The babeltrace issue was fixed in 1.1.1 release.  However, babeltrace
recent release (since 1.1.2) starts to complain about such faked
packet.  Here is a table shows that whether faked packet or no faked
packet is "supported" by various babeltrace releases,

        faked packet      no faked packet
1.1.0      Yes                 No
1.1.1      Yes                 Yes
1.1.2      No                  Yes
1.2.0      No                  Yes

We decide to get rid of this workaround in GDB, and people can build GDB
with libbabeltrace >= 1.1.1.  In this way, both configure and ctf.c is
simpler.

Run gdb.trace/* tests in the following combinations:

 wo/ this pattch  1.1.0
 w/  this patch   1.1.1
 w/  this patch   1.1.2
 w/  this patch   1.2.0

No test results change.

014f9477f4 constify to_open
This makes target_ops::to_open take a const string and then fixes the
fallout.

There were a few of these I could not build.  However I eyeballed it
and in any case the fixes should generally be trivial.

This is based on the patch to fix up the target debugging for to_open,
because that changes gdb to not directly install to_open as the target

290a839c9a Partially available/unavailable data in requested range
In gdb.trace/unavailable.exp, an action is defined to collect
struct_b.struct_a.array[2] and struct_b.struct_a.array[100],

struct StructB
{
  int d, ef;
  StructA struct_a;
  int s:1;
  static StructA static_struct_a;
  const char *string;
};

and the other files are not collected.

When GDB examine traceframe collected by the action, "struct_b" is
unavailable completely, which is wrong.

(gdb) p struct_b
$1 = <unavailable>

When GDB reads 'struct_b', it will request to read memory at struct_b's address
of length LEN.  Since struct_b.d is not collected, no 'M' block
includes the first part of the desired range, so tfile_xfer_partial returns
TARGET_XFER_UNAVAILABLE and GDB thinks the whole requested range is unavailable.

In order to fix this problem, in the iteration to 'M' blocks, we record the
lowest address of blocks within the request range.  If it has, the requested
range isn't unavailable completely.  This applies to ctf too.  With this patch
applied, the result looks good and fails in unavailable.exp is fixed.

(gdb) p struct_b
$1 = {d = <unavailable>, ef = <unavailable>, struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable>,
<unavailable>, -1431655766, <unavailable> <repeats 97 times>, -1431655766, <unavailable> <repeats 9899 times>}, ptr = <unavailable>, bitfield = <unavailable>}, s = <unavailable>,   static static_struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable> <repeats 10000 times>}, ptr = <unavailable>,
bitfield = <unavailable>}, string = <unavailable>}

48b6e87ef2 Unify ctf_fetch_registers and tfile_fetch_registers
Functions ctf_fetch_registers and tfile_fetch_registers have some
duplicated code about guessing the PC in regcache.  Sometimes, we
may change one function and forget to update the other one, like this
https://www.sourceware.org/ml/gdb-patches/2014-01/msg00292.html

This patch is to move the duplicated code into a new function
tracefile_fetch_registers, and let both ctf_fetch_registers and
tfile_fetch_registers call it.

614d5099da Get trace_regblock_size from metadata instead of event
In ctf trace, for each 'R' block, we save it as a "register" event,
as defined below in metadata.

event {
        name = "register";
        id = 0;
        fields := struct {
                ascii contents[440];
        };
}

Nowadays, we initialize trace_regblock_size by getting the length of
"contents" from a "register" event.  However, 'R' block may not exist
in traceframe, as a result, "register" event doesn't exist in trace file
and trace_regblock_size isn't set.

This patch changes to get trace_regblock_size from metadata (or declaration)
which always exists.

8acf9577e5 Move the traceframe_available_memory code from memory_xfer_partial_1 down to the targets
As a follow-up to

  [PATCH 7/8] Adjust read_value_memory to use to_xfer_partial
  https://sourceware.org/ml/gdb-patches/2014-02/msg00384.html

this patch moves traceframe_available_memory down to the target side.
After this patch, the gdb core code is cleaner, and code on handling
unavailable memory is moved to remote/tfile/ctf targets.

In details, this patch moves traceframe_available_memory code from
memory_xfer_partial_1 to remote target only, so remote target still
uses traceframe_info mechanism to check unavailable memory, and use
remote_ops to read them from read-only sections.  We don't use
traceframe_info mechanism for tfile and ctf target, because it is
fast to iterate all traceframes from trace file, so the summary
information got from traceframe_info is not necessary.

This patch also moves two functions to remote.c from target.c,
because they are only used in remote.c.  I'll clean them up in another
patch.

9b409511d0 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.

	* gdb.trace/while-stepping.exp: Likewise.
	* gdb.trace/report.exp: Test GDB saves trace data to CTF
	format and read CTF trace file if GDB supports.
