042e1521c7 Fix semaphore destruction (bug 12674).
This commit fixes semaphore destruction by either using 64b atomic
operations (where available), or by using two separate fields when only
32b atomic operations are available.  In the latter case, we keep a
conservative estimate of whether there are any waiting threads in one
bit of the field that counts the number of available tokens, thus
allowing sem_post to atomically both add a token and determine whether
it needs to call futex_wake.

9706dc5f53 Update copyright dates not handled by scripts/update-copyrights.
I've updated copyright dates in glibc for 2015.  This is the patch for
the changes not generated by scripts/update-copyrights and subsequent
build / regeneration of generated files.  Apart from the files updated
last time (of which sotruss.ksh had moved to sotruss.sh during the
year) this also updates nptl/version.c (missed from 2006 until
October) and sysdeps/unix/sysv/linux/lddlibc4.c (missed since 2009).

fc00cf7bcd Move semaphore.h to sysdeps/pthread/.
Carlos reported failures in conform/ tests in environments where the
compiler used could only find headers in glibc's source and build
trees, not any previously installed headers
<https://sourceware.org/ml/libc-alpha/2014-09/msg00040.html>.

This patch moves nptl/semaphore.h to sysdeps/pthread/semaphore.h so
that it can be found by builds from all glibc subdirectories; it's not
in any way NPTL-specific.  (I left the Makefile setting to install
this header in nptl/, but maybe it should move as well - it's just not
clear to me what ifeq ($(subdir),...) conditional should be used to
select the directory to associate the header with for installation
purposes.  The path in the toplevel Makefile used for begin-end-check
also remains hardcoded; it's a known todo issue to rework that test to
run in each subdirectory checking the headers installed from that
subdirectory, rather than a separate hardcoded list.)

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).  I did *not* test a
configuration such as that in which Carlos saw failure.

	* nptl/semaphore.h: Move to ...
	* sysdeps/pthread/semaphore.h: ... here.
	* Makefile (installed-headers): Change nptl/semaphore.h to
	sysdeps/pthread/semaphore.h.

c5c2b7c3fd Fix pthreads getrlimit, gettimeofday namespace (bug 17682).
Some pthreads functions use getrlimit and gettimeofday, but these
functions are XSI, not base POSIX; this is a namespace issue for
dynamic linking as well as static linking.  This patch makes them use
__getrlimit and __gettimeofday instead - the former needed to be newly
exported from libc.so at GLIBC_PRIVATE (and so now needs
libc_hidden_proto / libc_hidden_def), the latter was already exported.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

	[BZ #17682]
	* resource/Versions (libc): Add __getrlimit at GLIBC_PRIVATE.
	* resource/getrlimit.c (__getrlimit): Use libc_hidden_def.
	* sysdeps/mach/hurd/getrlimit.c (__getrlimit): Likewise.

909e16d960 Fix warning in nptl/tst-stack4.c.
This patch fixes a warning in a test that was added since my recent
warning cleanup:

tst-stack4.c: In function 'dso_process':
tst-stack4.c:64:7: warning: format '%i' expects argument of type 'int', but argument 3 has type 'uintptr_t' [-Wformat=]

The original variable has type int then is cast to uintptr_t, and from
there to void *, to pass it to a thread, so reversing the process by
casting to uintptr_t and then to int is natural; this patch does so.

Tested for x86_64.

	* nptl/tst-stack4.c (dso_process): Use int not uintptr_t for t.

4e0b901601 Fix -Waddress warnings in nptl/tst-mutex1.c.
This patch fixes -Waddress warnings in nptl/tst-mutex1.c from
comparing the address of an object with NULL (ATTR may either be NULL,
or the address of an object when included from other tests, and the
warning arises in the latter case).  A macro ATTR_NULL is defined
alongside ATTR and used for the tests.

Tested for x86_64.

	* nptl/tst-mutex1.c: Include <stdbool.h>.
	[!ATTR] (ATTR_NULL): New macro.
	(do_test): Test !ATTR_NULL instead of ATTR != NULL.
	* nptl/tst-mutexpi1.c (ATTR_NULL): New macro.

29955b5d96 Modify several tests to use test-skeleton.c
This patch modifies several test cases to use test-skeleton.c.
It was generated by a bash script written for this purpose and
thus excludes several other tests which I deemed worth a visual
inspection before making the change.

I intend to follow up with individual patches to the tests
skipped by the script.

The script itself resides at http://git.io/WODAmg and should
reproduce this very patch when run against master.

ba90e05052 Remove configuration name patterns from shlib-versions.
This patch removes the first column (patterns matching configuration
names) from shlib-versions, leaving shlib-versions entry selection
based purely on sysdeps directories.

An implication of this removal is that the default for any non-Linux
ports using NPTL will be the same SONAMEs for NPTL libraries as for
Linux (as those defaults, previously limited to .*-.*-linux.*, are
left in nptl/shlib-versions and nptl_db/shlib-versions).

Special host_os handling in configure.ac that was purely for
shlib-versions is removed.  (The host_os setting is still used for
libc-abis - see
<https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding
that - but no entries there are affected by this change.)

Tested on x86_64 and x86 that the installed shared libraries are
unchanged by this patch.

	* scripts/soversions.awk: Do not handle configuration names.
	* Makeconfig ($(common-objpfx)soversions.i): Do not pass cpu,
	vendor and os variables to soversions.awk.

dc932a24d9 Move architecture-specific shlib-versions entries to sysdeps files.
This patch eliminates another way in which ex-ports and non-ex-ports
architectures differ, by moving architecture-specific entries from the
top-level shlib-versions file and that in nptl/ to appropriate sysdeps
directories.  As with my previous patch
<https://sourceware.org/ml/libc-alpha/2014-06/msg00949.html>, I do not
change the regular expressions used; even where the present
expressions seem more general, I believe they are in fact specific to
the chosen sysdeps directory, because any port that matches the
expression but not the sysdeps directory does not currently exist, and
so would use different symbol versions if added in future (and an
intended goal of these changes is to eliminate the first column in
shlib-versions completely rather than having two different mechanisms
in use for system-specific configuration).

Tested on x86_64 that this does not change the installed shared
libraries.  (x86_64 of course does not provide much test coverage for
this patch - what should be architecture-specific contents in
shlib-versions for x86_64 is currently abi-*-ld-soname Makefile
settings, until gnu/lib-names.h is generated more like gnu/stubs.h so
those can move back to shlib-versions.)

	* nptl/shlib-versions: Remove architecture-specific entries.
	Moved to files in sysdeps.

	* sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: New
	file.

dd763fdb1e Remove NOT_IN_libc definition for pthread_atfork
pthread_atfork is already built in an extra-libs context, which gives
it NOT_IN_libc in its CPPFLAGS.  Adding the same definition to CFLAGS
is pointless.

If a call to the set*id functions fails in a multi-threaded program,

was triggered.

We address by checking that all calls to set*id on all threads give
the same result, and only abort if we see success followed by failure
(or vice versa).

11b076bbae Remove stray includes of kernel-features.h.
Now that files using __ASSUME_* macros have been made by
<https://sourceware.org/ml/libc-alpha/2014-06/msg00543.html> to
include <kernel-features.h> directly, any include from a file not
using __ASSUME_* macros can safely be removed (as there will no longer
be some other file relying on indirect inclusion via a header from
which the include is being removed).

This patch removes such unnecessary kernel-features.h includes.

Tested x86_64 that disassembly of installed shared libraries is
unchanged by this patch, except for line numbers in calls to
__assert_fail from libc.so and ld.so.

9bc6103d04 Include <kernel-features.h> explicitly where required.
This patch makes files using __ASSUME_* macros include
<kernel-features.h> explicitly, rather than relying on some other
header (such as tls.h, lowlevellock.h or pthreadP.h) to include it
implicitly.  (I omitted cases where I've already posted or am testing
the patch that stops the file from needing __ASSUME_* at all.)  This
accords with the general principle of making source files include the
headers for anything they use, and also helps make it safe to remove
<kernel-features.h> includes from any file that doesn't use
__ASSUME_* (some of those may be stray includes left behind after
increasing the minimum kernel version, others may never have been
needed or may have become obsolete after some other change).

8491ed6d70 Add adaptive elision to rwlocks
This patch relies on the C version of the rwlocks posted earlier.
With C rwlocks it is very straight forward to do adaptive elision
using TSX. It is based on the infrastructure added earlier
for mutexes, but uses its own elision macros. The macros
are fairly general purpose and could be used for other
elision purposes too.

This version is much cleaner than the earlier assembler based
version, and in particular implements adaptation which makes
it safer.

I changed the behavior slightly to not require any changes
in the test suite and fully conform to all expected
behaviors (generally at the cost of not eliding in
various situations). In particular this means the timedlock
variants are not elided.  Nested trylock aborts.

a832bdd362 Add a fast path for C rd/wrlock v2
One difference of the C versions to the assembler wr/rdlock
is that the C compiler saves some registers which are unnecessary
for the fast path in the prologue of the functions. Split the
uncontended fast path out into a separate function. Only when contention is
detected is the full featured function called. This makes
the fast path code (nearly) identical to the assembler version,
and gives uncontended performance within a few cycles.

v2: Rename some functions and add space.

686554bff6 Remove redundant C locale settings.
Various glibc build / install / test code has C locale settings that
are redundant with LC_ALL=C.

LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C
(explicitly, or through it being in the default environment for
running tests) does not need to set LANG=C.  LC_ALL=C also takes
precedence over LANGUAGE, since

2001-01-02  Ulrich Drepper  <drepper@redhat.com>

	* intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE
	value is ignored if the selected locale is the C locale.
	* intl/tst-gettext.c: Set locale for above change.
	* intl/tst-translit.c: Likewise.

and so settings of LANGUAGE=C are also redundant when LC_ALL=C is
set.  One test also had LC_ALL=C in its -ENV setting, although it's
part of the default environment used for tests.

This patch removes the redundant settings.  It removes a suggestion in
install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the
Makefile.in target "install" already sets LC_ALL_C so there's no need
for the user to set it (and nor should there be any need for the user
to set it).

If some build machine tool used by "make install" uses a version of
libintl predating that 2001 change, and the user has LANGUAGE set, the
removal of LANGUAGE=C from the Makefile.in "install" rule could in
principle affect the user's installation.  However, I don't think we
need to be concerned about pre-2001 build tools.

8540f6d2a7 Don't require test wrappers to preserve environment variables, use more consistent environment.
One wart in the original support for test wrappers for cross testing,
as noted in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the
requirement for test wrappers to pass a poorly-defined set of
environment variables from the build system to the system running the
glibc under test.  Although some variables are passed explicitly via
$(test-wrapper-env), including LD_* variables that simply can't be
passed implicitly because of the side effects they'd have on the build
system's dynamic linker, others are passed implicitly, including
variables such as GCONV_PATH and LOCPATH that could potentially affect
the build system's libc (so effectively relying on any such effects
not breaking the wrappers).  In addition, the code in
cross-test-ssh.sh for preserving environment variables is fragile (it
depends on how bash formats a list of exported variables, and could
well break for multi-line variable definitions where the contents
contain things looking like other variable definitions).

This patch moves to explicitly passing environment variables via
$(test-wrapper-env).  Makefile variables that previously used
$(test-wrapper) are split up into -before-env and -after-env parts
that can be passed separately to the various .sh files used in
testing, so those files can then insert environment settings between
the two parts.

The common default environment settings in make-test-out are made into
a separate makefile variable that can also be passed to scripts,
rather than many scripts duplicating those settings (for testing an
installed glibc, it is desirable to have the GCONV_PATH setting on
just one place, so just that one place needs to support it pointing to
an installed sysroot instead of the build tree).  The default settings
are included in the variables such as $(test-program-prefix), so that
if tests do not need any non-default settings they can continue to use
single variables rather than the split-up variables.

Although this patch cleans up LC_ALL=C settings (that being part of
the common defaults), various LANG=C and LANGUAGE=C settings remain.
Those are generally unnecessary and I propose a subsequent cleanup to
remove them.  LC_ALL takes precedence over LANG, and while LANGUAGE
takes precedence over LC_ALL, it only does so for settings other than
LC_ALL=C.  So LC_ALL=C on its own is sufficient to ensure the C
locale, and anything that gets LC_ALL=C does not need the other
settings.

While preparing this patch I noticed some tests with .sh files that
appeared to do nothing beyond what the generic makefile support for
tests can do (localedata/tst-wctype.sh - the makefiles support -ENV
variables and .input files - and localedata/tst-mbswcs.sh - just runs
five tests that could be run individually from the makefile).  So I
propose another subsequent cleanup to move those to using the generic
support instead of special .sh files.

79520f4bd6 Use existing makefile variables for dependencies on glibc libraries.
glibc's Makeconfig defines some variables such as $(libm) and $(libdl)
for linking with libraries built by glibc, and nptl/Makeconfig
(included by the toplevel Makeconfig) defines others such as
$(shared-thread-library).

In some places glibc's Makefiles use those variables when linking
against the relevant libraries, but in other places they hardcode the
location of the libraries in the build tree.  This patch cleans up
various places to use the variables that already exist (in the case of
libm, replacing several duplicate definitions of a $(link-libm)
variable in subdirectory Makefiles).  (It's not necessarily exactly
equivalent to what the existing code does - in particular,
$(shared-thread-library) includes libpthread_nonshared, but is
replacing places that just referred to libpthread.so.  But I think
that change is desirable on the general principle of linking things as
close as possible to the way in which they would be linked with an
installed library, unless there is a clear reason not to do so.)

To support running tests with an installed copy of glibc without
needing the full build tree from when that copy was built, I think it
will be useful to use such variables more generally and systematically
- every time the rules for building a test refer to some file from the
build tree that's also installed by glibc, use a makefile variable so
that the installed-testing case can point those variables to installed
copies of the files.  This patch just deals with straightforward cases
where such variables already exist.

It's quite possible some uses of $(shared-thread-library) should
actually be a new $(thread-library) variable that's set appropriately
in the --disable-shared case, if those uses would in fact work without
shared libraries.  I didn't change the status quo that those cases
hardcode use of a shared library whether or not it's actually needed
(but other uses such as $(libm) and $(libdl) would now get the static
library if the shared library isn't built, when some previously
hardcoded use of the shared library - if they actually need shared
libraries, the test itself needs an enable-shared conditional anyway).

Tested x86_64.

5a414ff70c S/390: Port of lock elision to System/z
Added support for TX lock elision of pthread mutexes on s390 and
s390x.  This may improve lock scaling of existing programs on TX
capable systems.  The lock elision code is only built with
--enable-lock-elision=yes and then requires a GCC version supporting
the TX builtins.  With lock elision default mutexes are elided via
__builtin_tbegin, if the cpu supports transactions. By default lock
elision is not enabled and the elision code is not built.

df5b85da90 Fix dwarf2 unwinding through futex functions.
When profiling programs with lock problems with perf record -g dwarf,
libunwind can currently not backtrace through the futex and unlock
functions in pthread. This is because they use out of line sections,
and those are not correctly described in dwarf2 (I believe needs
dwarf3 or 4).

This patch first removes the out of line sections. They only save a
single jump, but cause a lot of pain. Then it converts the now inline
lock code to use the now standard gas .cfi_* commands.

With these changes libunwind/perf can backtrace through the futex
functions now.

Longer term it would be likely better to just use C futex() functions
on x86 like all the other architectures. This would clean the code up
even more.

2e03fae7b7 hppa: Add _STACK_GROWS_* cases to pthread_attr_[sg]etstack.
This is one of a several NPTL patches to build glibc on hppa.

The pthread_attr_[sg]etstack functions are defined by POSIX as
taking a stackaddr that is the lowest addressable byte of the
storage used for the stack. However, the internal iattr variable
of the same name in NPTL is actually the final stack address
as usable in the stack pointer for the machine. Therefore the
NPTL implementation must add and subtract stacksize for
_STACK_GROWS_DOWN architectures. HPPA is a _STACK_GROWS_UP
architecture and doesn't need to add or subtract anything,
the stack address *is* the lowest addressable byte of the
storage.

Tested on hppa-linux-gnu, with no regressions.

Can't impact any other targets because of the conditionals.

If nobody objects I'll check this in at the end of the week.

I can't see there being any objections to this patch except
that it introduces more code to maintain for an old architecture
(perhaps we'll get another _S_G_U target in the future?).

0b20a9e89f Make tests consistently use *.out output files.
This patch systematically renames miscellaneous tests so their outputs
use a *.out name (unless the test is just running some glibc program
with its conventional output file name, rather than a special program
at all, as in catgets tests generating *.cat).  In the case of the
iconv test test-iconvconfig, output is redirected where it wasn't
before.

In various places the "generated" variable is updated to reflect the
revised test names; in iconvdata/Makefile a typo (mmtrace-tst-loading)
is also fixed.  resolv/Makefile sets both "generate" (which appears
unused) and "generated".  Bitrot in the settings of these variables
could no doubt be fixed so that "make clean" after build and testing
leaves results the same as after configure (and indeed the
tests-special / xtests-special variables could be used to simplify
things, by removing those files automatically rather than listing them
manually in these variables), and "make distclean" leaves an empty
build directory, but right now it appears various files don't get
deleted.  I think they are liable to continue to bitrot in the absence
of routine testing that these targets actually work, given that
building in the source directory isn't supported and that was the main
use of such makefile targets.

Tested x86_64.

f214606a0e Enumerate tests with special rules in tests-special variable.
This patch is a revised and updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>.

In order to generate overall summaries of the results of all tests in
the glibc testsuite, we need to identify and concatenate the files
with the results of individual tests.

Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this.
However, the normal glibc approach is explicit enumeration of the
expected set of files with a given property, rather than all files
matching some pattern like that.  Furthermore, we would like to be
able to mark tests as UNRESOLVED if the file with their results is for
some reason missing, and in future we would like to be able to mark
tests as UNSUPPORTED if they are disabled for a particular
configuration (rather than simply having them missing from the list of
tests as at present).  Such handling of tests that were not run or did
not record results requires an explicit enumeration of tests.

For the tests following the default makefile rules, $(tests) (and
$(xtests)) provides such an enumeration.  Others, however, are added
directly as dependencies of the "tests" and "xtests" makefile
targets.  This patch changes the makefiles to put them in variables
tests-special and xtests-special, with appropriate dependencies on the
tests listed there then being added centrally.

Those variables are used in Rules and so need to be set before Rules
is included in a subdirectory makefile, which is often earlier in the
makefile than the dependencies were present before.  We previously
discussed the question of where to include Rules; see the question at
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a
discussion in
<https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why
Rules is included early rather than late in subdirectory makefiles.

It was necessary to avoid an indirection through the check-abi target
and get the check-abi-* targets for individual libraries into the
tests-special variable.  The intl/ test $(objpfx)tst-gettext.out,
previously built only because of dependencies from other tests, was
also added to tests-special for the same reason.

The entries in tests-special are the full makefile targets, complete
with $(objpfx) and .out.  If a future change causes tests to be named
consistently with a .out suffix, this can be changed to include just
the path relative to $(objpfx), without .out.

Tested x86_64, including that the same set of files is generated in
the build directory by a build and testsuite run both before and after
the patch (except for changes to the
elf/tst-null-argv.debug.out.<number> file name), and a build with
run-built-tests=no to verify there aren't any more obvious instances
of the issue Marcus Shawcroft reported with a previous version in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>.

a5f891ac8d Consistently include Makeconfig after defining subdir.
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information.  No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.

This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules).  Includes are added if needed, or moved up if already
present.  Subdirectory "all:" targets are removed, since Makeconfig
provides one.

There is potential for further cleanups I haven't done.  Rules and
Makerules have code such as

ifneq   "$(findstring env,$(origin headers))" ""
headers :=
endif

to override to empty any value of various variables that came from the
environment.  I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable.  (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.)  Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves.  The special code to override values coming
from the environment would then be obsolete and could be removed.

Tested x86_64, including that installed binaries are identical before
and after the patch.

f0881698bf Generate .test-result files for tests with special rules.
This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now
proposed for inclusion in glibc, extends the generation of PASS and
FAIL status in .test-result files for individual tests to cover tests
with their own custom makefile rules.  This is just adding
$(evaluate-test) calls to all such rules, since tests with multiple
commands were previously split into separate tests.

Note that the tests the makefiles expect to fail (posix/annexc and
conformtest) currently get FAIL listed in the .test-result file,
rather than XFAIL; a subsequent patch will introduce a better XFAIL
mechanism.

6e89caf118 Split up rules for tests that compare output with baselines.
This patch splits makefile rules that generate a file then run cmp to
check the contents of that file into separate rules to generate and
compare the file.  This simplifies making those tests generate PASS /
FAIL results, by removing the need to insert && between commands in
the test so that a $(evaluate-test) call is reached.  It also avoids
the oddity of the .out file being an intermediate file rather than the
final result generated, as noted for some of these tests in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>.

In many cases, the rule to run the program was no longer needed
because the default rules for running test programs on the host to
generate a .out file sufficed.  (I'm not asserting the commands run
after this patch are *exactly* the same as before, simply that the
rules did nothing special that appeared deliberate or relevant to
anything about what the tests were testing.  In cases where the rules
redirected stderr as well as stdout, I left the existing rule's
redirection in place to avoid changing what gets compared with the
expected results.)

It's clear there is a lot in common between the various -cmp.out rules
and it might be possible in future to refactor them into more generic
support for the case of comparing test output against a baseline.
(Some baselines are *.exp, some *.expect, some directly embedded in
the makefiles, and nptl/tst-cleanupx0.expect appears unused.)

Support for /proc/self/task/$tid/comm as added in Linux 2.6.33,
therefore since the test tst-setgetname relies on this functionality
to operate we must skip the test in kernels < 2.6.33. We wrap the

8b8a692cfd PowerPC64 ELFv2 ABI 4/6: Stack frame layout changes
This updates glibc for the changes in the ELFv2 relating to the
stack frame layout.  These are described in more detail here:
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01149.html
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01146.html

Specifically, the "compiler and linker doublewords" were removed,
which has the effect that the save slot for the TOC register is
now at offset 24 rather than 40 to the stack pointer.

In addition, a function may now no longer necessarily assume that
its caller has set up a 64-byte register save area its use.

To address the first change, the patch goes through all assembler
files and replaces immediate offsets in instructions accessing the
ABI-defined stack slots by symbolic offsets.  Those already were
defined in ucontext_i.sym and used in some of the context routines,
but that doesn't really seem like the right place for those defines.

The patch instead defines those symbolic offsets in sysdeps.h,
in two variants for the old and new ABI, and uses them systematically
in all assembler files, not just the context routines.

The second change only affected a few assembler files that used
the save area to temporarily store some registers.  In those
cases where this happens within a leaf function, this patch
changes the code to store those registers to the "red zone"
below the stack pointer.  Otherwise, the functions already allocate
a stack frame, and the patch changes them to add extra space in
these frames as temporary space for the ELFv2 ABI.

b525166bb9 PowerPC64: Add __private_ss field to TCB header
The TCB header on Intel contains a field __private_ss that is used
to efficiently implement the -fsplit-stack GCC feature.

In order to prepare for a possible future implementation of that
feature on powerpc64, we'd like to reserve a similar field in
the TCB header as well.  (It would be good if this went in with
or before the ELFv2 patches to ensure that this field will be
available always in the ELFv2 environment.)

The field needs to be added at the front of tcbhead_t structure
to avoid changing the ABI; see the recent discussion when adding
the EBB fields.

http://sourceware.org/ml/libc-alpha/2013-08/msg00090.html

This patch fixes symbol versioning in setjmp/longjmp.  The existing
code uses raw versions, which results in wrong symbol versioning when
you want to build glibc with a base version of 2.19 for LE.

Note that the merging the 64-bit and 32-bit versions in novmx-lonjmp.c
and pt-longjmp.c doesn't result in GLIBC_2.0 versions for 64-bit, due
to the base in shlib_versions.

49186d21ef Disable elision for any pthread_mutexattr_settype call
PTHREAD_MUTEX_NORMAL requires deadlock for nesting, DEFAULT
does not. Since glibc uses the same value (0) disable elision
for any call to pthread_mutexattr_settype() with a 0 value.
This implies that a program can disable elision by doing
pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL)

Based on a original proposal by Rich Felker.

e8c659d74e Add elision to pthread_mutex_{try,timed,un}lock
Add elision paths to the basic mutex locks.

The normal path has a check for RTM and upgrades the lock
to RTM when available. Trylocks cannot automatically upgrade,
so they check for elision every time.

We use a 4 byte value in the mutex to store the lock
elision adaptation state. This is separate from the adaptive
spin state and uses a separate field.

Condition variables currently do not support elision.

Recursive mutexes and condition variables may be supported at some point,
but are not in the current implementation. Also "trylock" will
not automatically enable elision unless some other lock call
has been already called on the lock.

This version does not use IFUNC, so it means every lock has one
additional check for elision. Benchmarking showed the overhead
to be negligible.

1cdbe57948 Add the low level infrastructure for pthreads lock elision with TSX
Lock elision using TSX is a technique to optimize lock scaling
It allows to run locks in parallel using hardware support for
a transactional execution mode in 4th generation Intel Core CPUs.
See http://www.intel.com/software/tsx for more Information.

This patch implements a simple adaptive lock elision algorithm based
on RTM. It enables elision for the pthread mutexes and rwlocks.
The algorithm keeps track whether a mutex successfully elides or not,
and stops eliding for some time when it is not.

When the CPU supports RTM the elision path is automatically tried,
otherwise any elision is disabled.

The adaptation algorithm and its tuning is currently preliminary.

The code adds some checks to the lock fast paths. Micro-benchmarks
show little to no difference without RTM.

This patch implements the low level "lll_" code for lock elision.
Followon patches hook this into the pthread implementation

Changes with the RTM mutexes:
-----------------------------
Lock elision in pthreads is generally compatible with existing programs.
There are some obscure exceptions, which are expected to be uncommon.
See the manual for more details.

- A broken program that unlocks a free lock will crash.
  There are ways around this with some tradeoffs (more code in hot paths)
  I'm still undecided on what approach to take here; have to wait for testing reports.
- pthread_mutex_destroy of a lock mutex will not return EBUSY but 0.
- There's also a similar situation with trylock outside the mutex,
  "knowing" that the mutex must be held due to some other condition.
  In this case an assert failure cannot be recovered. This situation is
  usually an existing bug in the program.
- Same applies to the rwlocks. Some of the return values changes
  (for example there is no EDEADLK for an elided lock, unless it aborts.
   However when elided it will also never deadlock of course)
- Timing changes, so broken programs that make assumptions about specific timing
  may expose already existing latent problems.  Note that these broken programs will
  break in other situations too (loaded system, new faster hardware, compiler
  optimizations etc.)
- Programs with non recursive mutexes that take them recursively in a thread and
  which would always deadlock without elision may not always see a deadlock.
  The deadlock will only happen on an early or delayed abort (which typically
  happens at some point)
  This only happens for mutexes not explicitely set to PTHREAD_MUTEX_NORMAL
  or PTHREAD_MUTEX_ADAPTIVE_NP.  PTHREAD_MUTEX_NORMAL mutexes do not elide.

The elision default can be set at configure time.

This patch implements the basic infrastructure for elision.

e1f0b2cfa1 BZ #12310: pthread_exit in static app. segfaults
Static applications that call pthread_exit on the main
thread segfault. This is because after a thread terminates
__libc_start_main decrements __nptl_nthreads which is only
defined in pthread_create. Therefore the right solution is
to add a requirement to pthread_create from pthread_exit.

ba384f6ed9 C++11 thread_local destructors support
This feature is specifically for the C++ compiler to offload calling
thread_local object destructors on thread program exit, to glibc.
This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're
defined is unloaded by the dynamic linker.  The DSO is marked as
'unloadable' if it has a constructed thread_local object and marked as
'unloadable' again when all the constructed thread_local objects
defined in it are destroyed.
