undefined_msg is only used once contrary to the comment.

ChangeLog:

2014-06-23  Will Newton  <will.newton@linaro.org>

f393b4aaed elf/dl-lookup.c: Move STB_GNU_UNIQUE handling to a function
Move handling of STB_GNU_UNIQUE symbols to a separate function
from do_lookup_x in order to make the code more readable.

The new function gets inlined with gcc 4.8 on ARM and the
do_lookup_x code becomes a few bytes smaller.

ChangeLog:

2014-06-23  Will Newton  <will.newton@linaro.org>

	* elf/dl-lookup.c (do_lookup_unique): New function.
	(do_lookup_x): Move STB_GNU_UNIQUE handling code
	to a separate function.

c5c1335513 test-skeleton.c: Use stdout for error messages
At the moment the test skeleton uses a mixture of stdout and
stderr for error message output. Using stdout for all test output
keeps all output correctly ordered and properly redirected to the
output file. The suggestion to use stdout is also made on the wiki:

https://sourceware.org/glibc/wiki/Testing/Testsuite#Writing_a_test_case

ChangeLog:

2014-06-23  Will Newton  <will.newton@linaro.org>

	* test-skeleton.c (signal_handler): Use printf and %m
	rather than perror.  Use printf rather than fprintf to
	stderr.  Use puts rather than fputs to stderr.
	(main): Likewise.

bd3675f9a3 nscd: Remove unused typedef and variable.
The attached patch removed the unused ‘thread_info_t’ typedef and the
‘thread_info’ variable from nscd.c.  The former conflicts with a GNU Mach
typedef, and the latter conflicts with a GNU Mach function declaration:
<https://lists.gnu.org/archive/html/bug-hurd/2014-06/msg00101.html>.

2272ffc116 Remove ARM __ASSUME_SIGFRAME_V2.
This patch removes ARM __ASSUME_SIGFRAME_V2 now that the
2.6.18-and-later signal frame layout can be assumed, renaming the
affected functions accordingly now only one version of them is needed
in glibc.  (sigrestorer.S did not in fact include <kernel-features.h>
and it appears that, unlike other such cases, it didn't get the header
indirectly, so the v1 functions would have been compiled in even when
sigaction.c didn't reference them.)

(alpha and hppa also have architecture-specific __ASSUME_* macros that
should now be removed: __ASSUME_FDATASYNC and __ASSUME_LWS_CAS
respectively.  I don't have any plans to do anything on that myself.)

Tested on ARM.

	* sysdeps/unix/sysv/linux/arm/kernel-features.h
	(__ASSUME_SIGFRAME_V2): Remove macro.
	* sysdeps/unix/sysv/linux/arm/sigrestorer.S: Update comment.

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).

unchanged by this patch.

809fdf0d23 Remove __ASSUME_ATFCTS conditionals in sysdeps/unix/sysv/linux/.
This patch cleans up for __ASSUME_ATFCTS now always being true for the
supported Linux kernel versions by removing conditional code in
sysdeps/unix/sysv/linux.  Several fchownat.c files that were only
present because of differences in the fallback syscalls used
(depending on the architecture-specific names of chown-related
syscalls for 32-bit uids) are removed.  Files that looks like they
could be replaced by syscalls.list entries have the standard "Consider
moving to syscalls.list." comment (see bug 14138) added.  Conditionals
on the relevant __NR_* syscall numbers being defined are also removed,
since my analysis indicated that the relevant syscalls are always
defined for all relevant kernel versions using any affected file.
Much of the removed fallback code had unbounded stack allocations, so
this reduces the number of cases to consider for anyone reviewing uses
of alloca and VLAs in glibc.

There remain tests of __ASSUME_ATFCTS in io/openat.c (to determine
whether to define __have_atfcts) and sysdeps/posix/getcwd.c (which
also uses __have_atfcts); thus, the definition of __ASSUME_ATFCTS
remains in kernel-features.h.  The logical condition relevant there is
whether openat64_not_cancel_3 is known to work.  Hurd doesn't use this
version of getcwd at all, so the conditionals in getcwd.c are always
true in glibc.  However, this code is also used in gnulib.  So the
best way to deal with the conditionals there may be for gnulib people
to deal with merging all relevant changes in both directions between
the glibc and gnulib versions of this file, at the end of which the
openat conditionals should be in whatever form is best for gnulib, and
hardcoded in the _LIBC case to having openat supported.

Tested by comparing before-and-after disassembly of installed
(stripped) shared libraries, on x86_64 and x86.  On x86 the patch made
no change to the disassembly; on x86_64, the only changes were in
readlinkat, where formerly the return value from the readlinkat
syscall was stored in an int variable before being converted to
ssize_t for the return, and now the return value is returned directly
without truncation to int.  I think it's clearly correct not to
truncate the return value (although I also think the truncation would
not have been a user-visible bug because the kernel would never have
returned a value it could have affected).

4ba7a00fe3 Fix __ieee754_logl (-LDBL_MAX) in FE_DOWNWARD mode (bug 17022).
This patch fixes __ieee754_logl (-LDBL_MAX) on x86_64 and x86 not to
subtract 1 from its argument and so cause spurious overflow in
FE_DOWNWARD mode.  (For any argument strictly less than -1, it doesn't
matter whether or not 1 is subtracted before computing log1p, as long
as the result doesn't overflow to -Inf.)

Tested x86_64 and x86.  (This particular case lacks test coverage,
since the testsuite doesn't cover -lieee, but it will be covered by
tests after the following patch to test pow in all rounding modes,
which was the context in which this bug was found.)

	* sysdeps/i386/fpu/e_logl.S (__ieee754_logl): Do not subtract 1

85d8927856 Use $(rtld-prefix) more consistently.
The glibc makefiles have a standard variable, $(rtld-prefix), to run
the dynamic linker with a default --library-path option; this is used
as the basis of lots of other variables for running programs compiled
with the newly built library.

A few places however use $(elf-objpfx)ld.so or
$(elf-objpfx)${rtld-installed-name} directly, with such a
--library-path option.  This patch makes such places use
$(rtld-prefix) instead.  I'm not aware of any significance in these
cases to the choice of ld.so or ${rtld-installed-name} when running
the dynamic linker, or to whether $(patsubst
%,:%,$(sysdep-library-path)) is included in the library-path as it is
in $(rtld-prefix) and just one of the places being changed.

Tested x86_64.

	* elf/Makefile ($(objpfx)tst-unused-dep.out): Use $(rtld-prefix).
	* iconvdata/Makefile ($(inst_gconvdir)/gconv-modules)
	[$(cross-compiling) = no]: Likewise.
	* sysdeps/s390/s390-64/Makefile ($(inst_gconvdir)/gconv-modules)
	[$(cross-compiling) = no]: Likewise.

localedata/ChangeLog:
	* Makefile (LOCALEDEF): Use $(rtld-prefix).

754c5a08aa PowerPC: Fix nearbyintl failure for few inputs
This patch fixes few failures in nearbyintl() where the fraction part is
close to 0.5.i  The new tests added report few extra failures in
nearbyint_downward and nearbyint_towardzero which is a known issue.

Fixes #17031.

91c03c5389 Add CFI to x86 ceil / floor / trunc (bug 16681).
This patch adds CFI to the sysdeps/i386/fpu/ implementations of ceil,
floor and trunc functions, for consistency with other x86 .S files in
glibc which have CFI for stack adjustments.

Tested x86.
