On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency on Skylake
server. This patch changes the fallthrough code path to preserve
%xmm0 - %xmm7 registers instead:
if whole %zmm0 - %zmm7 registers are used
preserve %zmm0 - %zmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %xmm0 - %xmm7 registers
Tested on Skylake server.

The test malloc/tst-interpose-nothread fails on s390x if built
with GCC 7 and glibc commit "Remove the str(n)dup inlines
from string/bits/string2.h. Although inlining"
(ae65d4f3c3995279ca458c460ebf8bab1885fa03) with output:
error: free: 0x3fffdffa010: invalid allocation index: 0 (not less than 0)
The destructor check_for_allocations in malloc/tst-interpose-aux.c is
called twice. One time after the test-child-process has finished successfully
and once after the test-parent-process finishes.
During the latter invocation, allocation_index == 0. GCC 7 is now inlining the
free function and calls unconditionally fail in get_header as
header->allocation_index (type == size_t) is always >= allocation_index (= 0).
Before the mentioned commit above, strdup was replaced by strlen, malloc and
memcpy. The malloc call was also inlined and allocation_index was set to one.
This patch moves the already existing compiler barrier before the invocation
of free.
ChangeLog:
* malloc/tst-interpose-aux.c (check_for_allocations):
Move compiler barrier before free.

POSIX specifies long as the type of elements of struct mq_attr. For

sysdeps/unix/sysv/linux/alpha/bits/termios.h defines NL2 and NL3 for

The ia64-specific clone2 call expects the base of the stack mapping and
the stack size as sep arguments, not an initial stack value as on other
stack-grows-down architectures. Reuse the stack-grows-up macro so we
pass in the right stack base.

If a link (say /proc/self/fd/0) pointing to a device, say /dev/pts/2, in a
parent mount namespace is passed to ttyname, and a /dev/pts/2 exists (in a
different devpts) in the current namespace, then it returns /dev/pts/2.
But /dev/pts/2 is NOT the current tty, it is a different file and device.
Detect this case and return ENODEV. Userspace can choose to take this as a hint
that the fd points to a tty device but to act on the fd rather than the link.

sysdeps/unix/sysv/linux/sparc/bits/setjmp.h defines 64-bit __jmp_buf

sysdeps/unix/sysv/linux/alpha/bits/termios.h defines IXANY only if
__USE_MISC. But it's in the base standard for POSIX.1:2008, and
XSI-shaded in previous standards. This patch makes the header define
it unconditionally, like other versions of this header do (it's always
reserved by standards that don't require it, so defining
unconditionally is OK by the standards).
Tested (compilation only) for alpha with build-many-glibcs.py. Note
that there are still termios.h conformtest failures after this patch
because of other issues with the alpha version of this header.

As noted in bug 17786, MIPS o32 struct stat has the wrong type of
st_dev. This patch XFAILs that test in the conformtest expectations

also a similar issue for st_rdev that needs reporting and XFAILing
separately, and the bug should not be closed without an actual fix,
not just XFAILing).

This patch makes conformtest skip execution tests when
cross-compiling, as an interim step towards running most of these
tests (presently disabled) in that case. It omits the (obvious)
Makefile change to actually enable the conformtest tests when
cross-compiling, as there are still enough failures seen with
build-many-glibcs.py that I'd like to get the results cleaner before
enabling these tests.
Tested for x86_64, and with the tests actually enabled for
cross-compilation with build-many-glibcs.py.

conformtest has an internal XFAIL mechanism to allow failures of
individual expectations to be ignored, so that known hard-to-fix
failures (e.g. those affecting ABIs or requiring kernel changes) do
not cause the overall tests to FAIL and so hide other failures from
the same (header, standard) pair.
Various such bugs are system-specific, so this patch adds a mechanism
to allow system-specific XFAILs. A system-independent XFAIL is
achieved by putting "xfail-" at the start of the relevant expectation
in the *-data files. A system-specific XFAIL instead uses
"xfail[cond]-", where "cond" is a condition listed in
conformtest-xfail-conds in a sysdeps makefile (so one for x32 might
set conformtest-xfail-conds = x86_64-x32-linux, for example, and then
an expectation for tv_nsec's type could use
xfail[x86_64-x32-linux]-). The actual names are arbitrary, just
needing to match between the makefiles and the expectations, and if
necessary you can use "xfail[cond1|cond2]-" for a test that is
expected to fail under multiple conditions. As with
system-independent XFAILs, I think system-specific ones should have a
bug filed in Bugzilla and a comment referencing that bug.
Tested for x86_64, including with test expectations and makefiles
changed to use the new facility.
* conform/conformtest.pl ($xfail_str): New variable.
(--xfail=): New command-line option.
(top level): Handle expectations starting xfail[cond]-.

The conformtest header tests test some things through compilation
tests and others through execution tests. This patch makes more of
the tests into compilation tests, using _Static_assert (note: for
float.h tests on floating-point values this is depending on a GNU
extension, that those assertions are allowed in the absence of
-pedantic although they aren't strictly integer constant expressions).
The remaining execution tests are for values of things listed as
"symbol" (in fact no such things have a value expectation listed) and
for values of macros defined as string constants (three such values
listed in total).
This is intended as preparation for enabling the vast bulk of the
tests to run for cross compilation. (Even the few remaining execution
tests ought in principle to run for cross compilation when a test
wrapper is defined, but that's more complicated. The existing
execution tests for native builds in fact are linked and run with an
existing installed libc that's required to exist to link against,
rather than with the newly built libc; only the new headers are used.)
Tested for x86_64.
* conform/conformtest.pl: Use compilation instead of execution
tests for testing values of constants and usability in #if.

glibc headers include some code (not particularly consistent or
systematic) to put various declarations in C++ namespaces std and
__c99, if _GLIBCPP_USE_NAMESPACES is defined.
As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>,
this macro was removed from libstdc++ in 2000. I don't expect
compilation with such old versions of libstdc++ to work with current
glibc headers anyway (whereas old *binaries* are expected to stay
working with current glibc); this patch (which should be a no-op with
any libstdc++ version postdating that removal) removes all this code
from the glibc headers.
The begin-end-check.pl test, whose comments say it is about checking
these namespace macro calls, is also removed. The code in that test
would have covered __BEGIN_DECLS / __END_DECLS as well, but if those
weren't properly matched it would show up with the
check-installed-headers-cxx tests, so I don't think there is an actual
use for keeping begin-end-check.pl with the namespace code removed.

shared libraries are unchanged by the patch).

Bug 21094 reports 3ulp errors of cosf and tanf for certain arguments
near pi/2 arising from the use of an insufficiently accurate range
reduction. (To be clear, this is a quality-of-implementation issue
relating to the apparent intent of those particular cosf and tanf
implementations; 3ulp is within the general glibc accuracy goals, so
not inherently a bug.)
This patch fixes that error by making a wider range of cases use the
existing more accurate range reduction for arguments close to pi/2.
The wider range of values is still narrow enough for the "z -=
pio2_2;" in the more accurate case to be exact, as the code expects.
Tested for x86_64, x86 and mips64; no ulps updates needed (but at
least on mips64, the larger ulps were seen if the tests were added
without the substantive fix).

The binutils package was recently changed to fix -z relro support on hppa.
See ld/21000 for details:
https://sourceware.org/bugzilla/show_bug.cgi?id=21000
This exposed a problem with the _dl_start_user function in the RTLD_START
define. We need to set __libc_stack_end before it is made read only. For
this, we need to define DL_STACK_END. The offset of 0x160 gives the same
stack end as the code in _dl_start_user.

The test for "-z combreloc" fails when cross-compiling on a machine
that uses BSD grep (e.g. on macos). grep complains about empty
subexpression and exits with non-zero status, which is interpreted
by configure as "not found". As a result, support for "-z combreloc"
(HAVE_Z_COMBRELOC) is not detected, leading to link failure on SPARC.
While there, replace fgrep with 'grep -F', as fgrep is non-POSIX.

This patch fixes multiple issues of test-errno.c (9a56f8718341):
- Rename Linux test-errno.c to test-errno-linux.c to avoid build
the same source for both tests.
- Add a mlock check for 32 bits build running on 64 bits kernels.
Althuough man pages states that mlock fails with EINVAL if final
address overflows, kernels does not return it for aforementioned
condition (it returns ENOMEM instead). Although it seems to be
a kernel issue for compat syscall handling, I think it is worth
to still check syscall return and document the behavior.
- Initialize option lenght for setsockopt check.
- Change open test from EINVAL to EISDIR.
Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits
kernel).

x86_64 libmvec tests have been failing to build lately with GCC
mainline with -Wuninitialized errors, and Markus Trippelsdorf traced
this to an aliasing issue
<https://sourceware.org/ml/libc-alpha/2017-03/msg00169.html>.
This patch fixes the aliasing issue, so that the vectors-of-pointers
are initialized using a union instead of pointer casts. This also
fixes the testsuite build failures with GCC mainline.

The classification macros: finite, fpclassify, iseqsig, isinf, isnan,
issignaling, and signbit are defined by ISO C11 and declared in
mathcalls.h for each of the floating-point types: float, double, and
long double.
TS 18661-3 does not mention these macros for float128, however support
for them must be present when _Float128 is present. This is true,
even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is
false. Other function declarations in mathcalls.h, on the other hand,
depend on __STDC_WANT_IEC_60559_TYPES_EXT__.
This patch splits the helper functions (__finite, __fpclassify,
__iseqsig, __isinf, __isnan, __issignaling, and __signbit) from
mathcalls.h, so that these helper functions can be declared for
_Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false.

Before this change, the loop iterating over RRs in the answer
section stopped at the first CNAME record, never printing them.
The CNAME and PTR record contents was extracted from the wrong

* sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c: Add
posix_fadvise64 weak_alias for static build.

Thanks David Michael for the suggestion.
* sysdeps/mach/hurd/send.c (__send): Convert hurdish error code into
posix error code.
* sysdeps/mach/hurd/recv.c (__recv): Likewise.

Now with d40dbe7 SH build does not require more the no_isolate gcc
options to correct build glibc (since SH build now does not generate
a trap anymore). This patch removes the unrequired options from
SH config.
Checked with a build for sh3-linux-gnu, sh3eb-linux-gnu, sh4-linux-gnu,
and sh4eb-linux-gnu.
* scripts/build-many-glibcs.py (Context.add_all_configs): Remove
no_isolate usage for SH.

calls with constant strings shows a small (~10%) performance gain, strdup is
typically used in error reporting code, so not performance critical.
Remove the now unused __need_malloc_and_calloc related defines from stdlib.h.
Rename existing uses of str(n)dup to __str(n)dup so it no longer needs to be
redirected to a builtin. Also building GLIBC with -Os now no longer shows
localplt or linkname space failures (partial fix for BZ #15105 and BZ #19463).

Linux 4.10 adds IPV6_RECVFRAGSIZE to include/uapi/linux/in6.h, which
shows that several such IPV6_* macros are missing from glibc's
sysdeps/unix/sysv/linux/bits/in.h (while older ones are present). I
don't know whether any of these might be deliberately omitted, but
this patch adds what appear to be the missing more recent macros to
glibc.
Tested for x86_64.

macro.

Build glibc for sh4-unknown-linux-gnu currently fails if one's
using GCC5/6: in dl-conflict.c, the elf_machine_rela() function
is called with NULL as its 3rd argument, sym. The implementation
of that function in sysdeps/sh/dl-machine.h dereferences that pointer:
const Elf32_Sym *const refsym = sym;
...
if (map == &GL(dl_rtld_map))
value -= map->l_addr + refsym->st_value + reloc->r_addend;
GCC discovers a null pointer dereference, and in accordance with
-fdelete-null-pointer-checks (which is enabled in -O2) replaces this
code with a trap - which, as SH does not implement a trap pattern in
GCC, evaluates to an abort() call. This abort() call pulls many more
objects from libc_nonshared.a, eventually resulting in link failure
due to multiple definitions for a number of symbols.
As far as I see, the conditional before this code is always false in
rtld: _dl_resolve_conflicts() is called with main_map as the first
argument, not GL(_dl_rtld_map), but since that call is in yet another
compilation unit, GCC does not know about it. Patch that wraps this
conditional into !defined RESOLVE_CONFLICT_FIND_MAP attached.
* sysdeps/sh/dl-machine.h (elf_machine_rela): The condition
in R_SH_DIR32 case is always false when inlined from
dl-conflict.c. Ifdef out to prevent GCC from insertin an
abort() call.

librpcsvc.a should not be installed, too.
* sunrpc/Makefile: don't build and install rpcsvc header
files, rpcgen and librpcsvc.a by default.
