This patchs adds plugin_input_file_t to implement get_input_file, get_view
and release_input_file. The maximum memeory overhead per IR input file
are about 40 bytes for plugin_input_file_t plus the memory to store input
IR filename. According to
http://gcc.gnu.org/wiki/whopr/driver
RELEASE_INPUT_FILE: Function pointer to the linker interface that
releases a file descriptor for a claimed input file. The plug-in library
must call this interface for each file descriptor obtained by the "get
input file" interface. It must release all such file descriptors before
returning from the WPA phase.
However, GCC plug-in library doesn't use the "get input file" interface.
It processed the IR input in the claim file handler. Since the the file
descriptor opened for the IR input was unused after the claim file
handler returns and GCC plug-in library before GCC 5 doesn't call the
RELEASE_INPUT_FILE function pointer, ld closed the file descriptor to
avoid leaking file descriptor. But this approach doesn't work with
other plug-in libraries which uses the "get input file", "get view" and
"release input file" interfaces. To avoid file descriptor leak with
GCC prior to GCC 5 and support other plug-in libraries at the same time,
we close the file descriptor only if the input IR file is a bfd_object
file. This scheme doesn't work when a plug-in library needs the file
descriptor and its IR is stored in bfd_object file.

gcc-5 correctly complains "loop exit may only be reached after
undefined behavior". I was going to correct this by checking the
index before dereferencing the array rather than the other way around,
but then I noticed it is possible for extract_cmd to write the
terminating zero one past the end of "cmd". Fixing that means no
index check is needed in md_assemble.
* config/tc-msp430.c (md_assemble): Correct size passed to
extract_cmd. Remove index check.

This commit modifies the test program gdb.base/info-os.c so that
it cleans up all allocated System V IPC objects when a fatal
error occurs. Without this, it was possible for the program
to leave IPC objects on the system, and such objects persist
until they are manually deleted or the system reboots.
I looked at changing the SysV IPC key for allocating the IPC objects to
IPC_PRIVATE. That would prevent errors due to namespace conflicts with the
key. However, the test needs to read the actual key number from the 'info
os' command output, and IPC_PRIVATE won't work for that.

on Fedora Rawhide (==22) i686 using --with-python=/usr/bin/python3 one gets:
./python/py-value.c:1696:3: error: initialization from incompatible pointer type [-Werror]
valpy_hash, /*tp_hash*/

cc1: all warnings being treated as errors
Makefile:2628: recipe for target 'py-value.o' failed
This is because in Python 2 tp_hash was:
typedef long (*hashfunc)(PyObject *);
while in Python 3 tp_hash is:
typedef Py_hash_t (*hashfunc)(PyObject *);
Py_hash_t is int for 32-bit hosts and long for 64-bit hosts. While on 32-bit
hosts sizeof(long)==sizeof(int) still the hashfunc type is formally
incompatible. As this patch should have no compiled code change it is not
really necessary for gdb-7.9, it would fix there just this non-fatal
compilation warning:

Since the starvation avoidance series
(https://sourceware.org/ml/gdb-patches/2014-12/msg00631.html), both
GDB and GDBserver pull all events out of ptrace before deciding which
event to process.
There's one problem with that though. Because we resume new threads
immediately when we see a PTRACE_EVENT_CLONE event, if the program
constantly spawns threads fast enough, new threads can spawn threads
faster we can pull events out of the kernel, and thus we'd get stuck
in an infinite loop, never returning any event to the core to process.
I occasionally see this happen with the
attach-many-short-lived-threads.exp test against gdbserver.
The fix is to delay resuming new threads until we've pulled out all
events out of the kernel.
On native, we already have the resume_stopped_resumed_lwps function
that knows to resume LWPs that are stopped with no event to report to
the core. So the patch just adds another use. GDBserver didn't have
the equivalent yet, so the patch adds one.
Tested on x86_64 Fedora 20, native and gdbserver (remote and
extended-remote).

Running the testsuite with the native-extended-gdbserver.exp board and
passing a variant spec, like
make check RUNTESTFLAGS="--target_board=native-extended-gdbserver/-m32"
results in dejagnu trying to open a rsh connection to
"native-extended-gdbserver", which of course is wrong. The point of
this board is running things locally.
The issue is that the native-extended-gdbserver board does not clear
the "isremote" flag properly.

When reading a core file register section which is larger than
expected, emit a warning. Assume that a register section usually has
exactly the size specified by the regset section iterator. In some
special cases this assumption is wrong, or at least does not match the
regset supply function's logic. Thus also add a way to suppress the
warning in those cases, using a new flag REGSET_VARIABLE_SIZE.

* regset.h (struct regset): Add flags field.
(REGSET_VARIABLE_SIZE): New value for a regset's flags field.
* corelow.c (get_core_register_section): Add warning if the size

When reading the XSAVE extended state from an i386 or AMD64 core file,
the respective regset iterator requests a minimum section size of
zero. Since the respective regset supply function does not check the
size either, this may lead to accessing data out of range if the
section is too short.
In write mode, the iterator always uses the maximum supported size for
the XSAVE extended state.
This is now changed such that the iterator always requests the
expected size of this section based on xcr0, both for reading and
writing.
gdb/ChangeLog:
* amd64-linux-tdep.c (amd64_linux_iterate_over_regset_sections):
For ".reg-xstate", explicitly specify the requested section size
via X86_XSTATE_SIZE instead of just 0 on input and
X86_XSTATE_MAX_SIZE on output.

As reported in PR 17808, a test case with a forged (invalid) core file
can crash GDB with an assertion failure. In that particular case the
prstatus of an i386 core file looks like that from an AMD64 core file.
Consequently the respective regset supply function i386_supply_gregset
is invoked with a larger buffer than usual. But i386_supply_gregset
asserts a specific buffer size, and this assertion fails.
The patch relaxes all buffer size assertions in regset supply
functions such that they merely check for a sufficiently large buffer.
For consistency the regset collect functions are adjusted as well.

With global system gcc-5.0 if one also installs ccache (needing a different

https://bugzilla.samba.org/show_bug.cgi?id=11060

Even with the previous patch installed, we'll still see
sigall-reverse.exp occasionally fail. The problem is that the event
loop's event handling processing is done in two steps:
#1 - poll all event sources, and push new event objects to the event
queue, until all event sources are drained.
#2 - go through the event queue, processing each event object at a
time. For each event, call the associated callback, and deletes the
event object from the queue.
and then bad things happen if between #1 and #2 something decides that
events from an event source that has already queued events shouldn't
be processed yet. To do that, we either remove the event source from
the list of event sources, or clear its "have events" flag. However,
if an event for that source has meanwhile already been pushed in the
event queue, #2 will still process it and call the associated
callback...
One way to fix it that I considered was to do something to the event
objects already in the event queue when an event source is no longer
interesting. But then I couldn't find any good reason for the
two-step process in the first place. It's much simpler (and less
code) to call the event source callbacks as we poll the sources and
find events.

This is another event-loop/async related problem exposed by the patch
that made 'query' use gdb_readline_wrapper (588dcc3edbde19f9).
The problem is that even though gdb_readline_wrapper disables
target-async while the secondary prompt is in progress, the record
target's async event source is left marked. So when
gdb_readline_wrapper nests an event loop to process input, it may
happen that that event loop ends up processing a target event while
GDB is not really ready for it. Here's the relevant part of the
backtrace showing the root issue in action:

In all these cases we're interested in whether the target is currently
async, with its event sources installed in the event loop, not whether
it can async if needed. Also, I'm not seeing the point of the

resume instead, which this target already does.
