alpha: Update libm-test-ulps
alpha: Fix isnan

The isunordered formulation raises SIGFPE for SNaN.
Add missing #include for MIN/MAX users.
hppa: Add ABI baselines.

The following ABI baselines were tested against several old releases
of debian and gentoo. Several problems were discovered and fixed as
part of developing the ABI baselines.

Firstly, libBrokenLocale on gentoo exports __ctype_get_mb_cur_max
as @@GLIBC_2.0, but it should be @@GLIBC_2.2 since that's the minimum
version defined in shlib-versions for hppa. I don't know when this
broke, but master properly parses hppa's shlib-versions which clearly
lists libBrokenLocale as defaulting to GLIBC_2.2. Therefore I'm
accepting GLBIC_2.2 as the correct version for this symbol and setting
the baseline to that, despite the fact that the present distribution
is wrong. I don't expect that any new applications should be using
libBrokenLocale, so it should match the oldest behaviour which is to
export a GLIBC_2.2 symbol. For example in debian's 2.7 has it at
version GLIBC_2.2.

Secondly, aio_cancel and aio_cancel64 previously had a compat symbol
at version @GLIBC_2.1 with a new symbol at @@GLIBC_2.3[1]. During the
Linuxthreads to NPTL transition the file aio_cancel.c was lost for hppa
and that resulted in just @@GLIBC_2.1 versions of these symbols being
exported. The @@GLIBC_2.1 version works correctly and uses the right
value of ECANCELLED. Therefore if I were to fix this today it might
break correctly working applications using aio_cancel*@GLIBC_2.1 by
causing those to use the old aio_cancel that used the older value
of ECANCELLED. Thus the best option is to accept that the ABI changed
and ignore older applications in favour of newer applications. The
best thing to do is cleanup the version files (included in the patch).

The rest of the ABI was as expected (ignoring __p_type_syms size
change in 2008).
hppa: Remove GLIBC_2.3 from librt.abilist.

This commit removes the aio_cancel and aio_cancel64 symbols at
GLIBC_2.3 from the ABI baseline. The ABI baseline is now complete
for hppa and considered stable.
Add comment to gethnamaddr.c to warn that the file is unmaintained
misc/sys/cdefs.h: Add _Noreturn macro for pre-C11 compilers

2014-07-02  Will Newton  <will.newton@linaro.org>
	    Paul Eggert  <eggert@cs.ucla.edu>

	* misc/sys/cdefs.h (_Noreturn): New macro, for pre-C11 compilers.
malloc/obstack: Merge from gnulib

Merge the latest version of the obstack.c and obstack.h files
from gnulib. The majority of this change is coding style and
cosmetic comment changes but it also fixes a -Wundef warning
in the build as a side effect.

2014-07-02  Will Newton  <will.newton@linaro.org>

	* malloc/obstack.c: Merge from gnulib master.
	[HAVE_CONFIG_H]: Remove conditional code.
	[!_LIBC]: Include config.h.
	[!ELIDE_CODE]: Don't include inttypes.h, include
	stdint.h unconditionally.
	(print_and_abort): Mark as _Noreturn.
	(_obstack_allocated_p): Mark as __attribute_pure__.
	(obstack_free): Rename to __obstack_free.
	[!__attribute__]: Remove conditional code.
	* malloc/obstack.h: Merge from gnulib master.
	[__cplusplus]: Move conditional down.
	[!__attribute_pure__]: Define __attribute_pure__ here
	if it is not already defined.
	(_obstack_memory_used): Mark as __attribute_pure__.
	[!__obstack_free]: Define as obstack_free.
	[__GNUC__]: Remove check for ancient NeXT gcc.
Fix typo in macro name

It is _POSIX_SIGNALS and not _POSUX_SIGNALS
Fix typo and formatting in loadmsgcat.c

This reduces the differences with gettext version of loadmsgcat.c
Add missing #include for MIN use in dl-sysdep.c.
PowerPC: strcat optimization for PPC64/POWER7

This patch adds an ifunc power7 strcat symbol that uses the logic on
sysdeps/powerpc/strcat.c but call power7 strlen/strcpy symbols instead
of default ones.
Fix -Wundef warning on PAGE_COPY_THRESHOLD

The PAGE_COPY_THRESHOLD macro is meant to be overridden by
architecture-specific pagecopy.h, but it is currently done only by
mach; all other architectures use the default.  Check to see if the
macro is defined in addition to whether it is set to a non-zero value.
Don't use __glibc_unlikely in shared code
Fix Wundef warning for __STDC_VERSION__

c4c4124473c187b5c4642611390897666c3d3970 added the _Noreturn macro for
pre-C11 compilers, but it now throws a new Wundef warning during `make
check` for __STDC_VERSION__ which gcc does not define by default.  The
following patch fixes this in line with other uses of __STDC_VERSION__
in the file.
Sync up loadmsgcat.c with gettext
stdlib/tst-strtod-overflow: Bump timeout up yet

This test case is very, especially on targets using soft-float or QEMU
(where soft-float is used internally), and appears to be the only such
outlier.  Therefore rather than requiring to have TIMEOUTFACTOR set
large enough globally, bump up the local scaling factor instead.

	* stdlib/tst-strtod-overflow.c (TIMEOUT): Bump up to 30.
powerpc: Remove dummy hp-timing.h

It's the same as the generic dummy version.
Removing HP_TIMING_ZERO as unused
Removing HP_TIMING_ACCUM as unused
