0ddb7ea842 nptl: Assume __ASSUME_FUTEX_CLOCK_REALTIME support
This patch assumes realtime clock support for nptl and thus removes
all the associated code.

For __pthread_mutex_timedlock the fallback usage for the case where
lll_futex_timed_wait_bitset it not set define is also removed. The
generic lowlevellock-futex.h always define it, so for NPTL code the
check always yield true.

Checked on x86_64-linux-gnu and i686-linux-gnu.

	* nptl/nptl-init.c (__have_futex_clock_realtime,
	__have_futex_clock_realtime): Remove definition.
	(__pthread_initialize_minimal_internal): Remove FUTEX_CLOCK_REALTIME

590675c079 powerpc: Fix build of wcscpy with --disable-multi-arch
Since the commit

commit 81a1443941
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Tue Feb 5 17:35:12 2019 -0200

    wcsmbs: optimize wcscat

powerpc64 and powerpc64le builds fail when configured with
--disable-multi-arch and --with-cpu=power6 (or newer), due to an
undefined reference to __GI___wcscpy.  This patch fixes this on
sysdeps/powerpc/powerpc64/power6/wcscpy.c, which is only used when
multi-arch is disabled.

This patch does nothing for the failures on 32-bits powerpc builds,
because the file is under the powerpc64 subdirectory, however, powerpc
builds were already failing with --disable-multi-arch, with multiple
error messages, even before the aforementioned commit.

Tested for powerpc, powerpc64, and powerpc64le with multi-arch enabled
(all pass) and disabled (powerpc still fails as explained above).

f0eaf86276 ldbl-opt: Reuse test cases from misc/ that check long double
This patch adds test cases for the compatibility versions of the
functions: err, errx, verr, verrx, warn, warnx, vwarn, vwarnx (from
err.h), error, and error_at_line (from error.h), when long double has
the same format as double (-mlong-double-64).

Tested for powerpc, powerpc64 and powerpc64le.

d11086a939 ldbl-opt: Add error and error_at_line (bug 23984)
On platforms where long double may have the same format as double
(-mlong-double-64), error and error_at_line do not take that into
account and might produce wrong output if a long double conversion is
requested by the format string ('%Lf').  This patch adds compatibility
functions for this situation and redirects calls via header magic.

Tested for powerpc, powerpc64 and powerpc64le.

90188e7d1a ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug 23984)
When support for long double format with 128-bits (-mlong-double-128)
was added for platforms where long double had the same format as double,
such as powerpc, compatibility versions for the functions listed in the
commit title were missed.  Since the older format of long double can
still be used (with -mlong-double-64), using these functions with a
format string that requests the printing of long double variables will
produce wrong outputs.

This patch adds the missing compatibility functions and header magic to
redirect calls to them when -mlong-double-64 is in use.

Tested for powerpc, powerpc64 and powerpc64le.

c259196b50 elf/tst-big-note: Improve accuracy of test [BZ #20419]
It is possible that the link editor injects an allocated ABI tag note
before the artificial, allocated large note in the test.  Note parsing
in open_verify stops when the first ABI tag note is encountered, so if
the ABI tag note comes first, the problematic code is not actually
exercised.

Also tweak the artificial note so that it is a syntactically valid
4-byte aligned note, in case the link editor tries to parse notes and
process them.

Improves the testing part of commit 0065aaaaae.

cc3e573ce3 elf: Add tests with a local IFUNC resolver [BZ #23937]
The existing tests all use global symbols (but with different
visibility).  Local symbols could be treated differently by the
compiler and linker (as was the case on POWER ELFv2, causing
bug 23937), and we did not have test coverage for this.

Tested on x86-64 and POWER ELFv2 little-endian, with and without
--disable-multi-arch.  On POWER, the test cases elf/ifuncmain9,
elf/ifuncmain9pic, elf/ifuncmain9pie reproduce bug 23937 with older

34a5a1460e Break some lines before not after operators.
The GNU Coding Standards specify that line breaks in expressions
should go before an operator, not after one.  This patch fixes various
code to do this.  It only changes code that appears to be mostly
following GNU style anyway, not files and directories with
substantially different formatting.  It is not exhaustive even for
files using GNU style (for example, changes to sysdeps files are
deferred for subsequent cleanups).  Some files changed are shared with
gnulib, but most are specific to glibc.  Changes were made manually,
with places to change found by grep (so some cases, e.g. where the
operator was followed by a comment at end of line, are particularly
liable to have been missed by grep, but I did include cases where the
operator was followed by backslash-newline).

This patch generally does not attempt to address other coding style
issues in the expressions changed (for example, missing spaces before
'(', or lack of parentheses to ensure indentation of continuation
lines properly reflects operator precedence).

f43b8dd555 Add internal implementations for argp.h, err.h, and error.h functions
Since the introduction of explicit flags in the internal implementation
of the printf family of functions, the 'mode' parameter can be used to
select which format long double parameters have (with the mode flag:
PRINTF_LDBL_IS_DBL).  This patch uses this feature in the implementation
of some functions in argp.h, err.h, and error.h (only those that take a
format string and positional parameters).  Future patches will add
support for 'nldbl' and 'ieee128' versions of these functions.

4a2dd41cb5 powerpc64le: Remove test for GCC 6.2
The configure fragment for powerpc64le contains a test for the presence
of several compiler builtins and of the __float128 type, which are
provided by GCC 6.2 for powerpc64le.  Since this configure test was
added, the compiler version required to build glibc for powerpc64le was
different than that required for the other architectures.

Now that glibc requires GCC 6.2 globally (since commit ID 4dcbbc3b28),
this patch removes the powerpc64le-specific test.

Even tough the configure test checks for compiler features rather than
compiler version, the intent of the test was to stop build attempts at
early stages, if they had been configured with a too old compiler.  It
was not the intention of the test to detect compiler breakage (such as
the removal of the required compiler features in future GCC versions),
and glibc is not the place to test for compiler regressions, anyway.

Tested for powerpc64le with GCC 6.2 (built with build-many-glibcs.py).

8c9289b642 Fix SPARC64 handling of R_SPARC_H34 (bug 24231).
Building glibc with -Wextra shows a -Wimplicit-fallthrough warning for
SPARC64 that appears to be a real bug in glibc.  The dynamic linker
handling of R_SPARC_H34 falls through to that of R_SPARC_H44, which in
the case of this code is nonsensical (it means the value computed for
R_SPARC_H34 gets overwritten by one computed with the different logic
for R_SPARC_H44).  Thus, this patch adds the missing break there.
Note: I do not have a testcase to demonstrate this bug.

a5406364ac libio: Eliminate _IO_stdin, _IO_stdout, _IO_stderr
These variables are only used to determine if a stdio stream is
a pre-allocated stream, but it is possible to do so by comparing
a FILE * to all pre-allocated stream objects.  As a result, it is
not necessary to keep those pointers in separate variables.

Behavior with symbol interposition is unchanged because _IO_stdin_,
_IO_stdout_, _IO_stderr_ are exported, and refer to objects outside of
libc if symbol interposition or copy relocations are involved.  (The
removed variables _IO_stdin, _IO_stdout, _IO_stderr were not exported,
of course.)

6c29942cbf misc/tst-clone3: Fix waiting for exited thread.
From time to time the test misc/tst-clone3 fails with a timeout.
Then futex_wait is blocking.  Usually ctid should be set to zero
due to CLONE_CHILD_CLEARTID and the futex should be waken up.
But the fail occures if the thread has already exited before
ctid is set to the return value of clone().  Then futex_wait() will
block as there will be nobody who wakes the futex up again.

This patch initializes ctid to a known value before calling clone
and the kernel is the only one who updates the value to zero after clone.
If futex_wait is called then it is either waked up due to the exited thread
or the futex syscall fails as *ctid_ptr is already zero instead of the
specified value 1.

ChangeLog:

	* sysdeps/unix/sysv/linux/tst-clone3.c (do_test):
	Initialize ctid with a known value and remove update of ctid
	after clone.
	(wait_tid): Adjust arguments and call futex_wait with ctid_val
	as assumed current value of ctid_ptr.

ad18dadec9 Add check for missing wrapper headers
If building on a subset of architectures only, it is easy to miss
wrapper headers which are required by other architectures because
they lack the corresponding sysdeps header.  The check ensures
that every installed header which is not itself a sysdeps header
has a header under include/ (that presumably wraps the header,
and perhaps also adding declarations and definitions for !_ISOMAC).

Also check for the absence of the sysdeps/generic/bits directory
removed in commit c72565e5f1, to make

e442e40de5 io: Consolidate lockf implementation
With internal fcntl64 internal (commit 06ab719d), it is possible to
consolidate lockf implementation by using the LFS fcntl interface
instead of using arch and system-specific implementations.

For Linux, the i386 implementation is used as generic implementation
by replacing the direct syscall with fcntl64 call.  The LFS symbol
alias for default LFS ABI (__OFF_T_MATCHES_OFF64_T) is used to avoid
the duplicate symbol (instead of overriding the implementation with an
empty file).

For Hurd lockf64 semantic is changed: previous generic lockf64
implementation returned EOVERFLOW if LEN input is larger than 32-bit
off_t.  However, Hurd fcntl64 implementation for F_GETLK64, F_SETLK64,
and F_SETLKW64 do accept off64_t inputs (__f_setlk accepts only off64_t
inputs).

build.

712182c8dc Fix fall-through warnings in sunrpc/xdr.c.
This patch fixes implicit-fallthrough warnings in sunrpc/xdr.c when
building with -Wextra.  A fall-through comment is added in three
places; in two other places, an existing comment is reworded so it
matches the default patterns used by -Wimplicit-fallthrough.

Tested for x86_64.

	* sunrpc/xdr.c (xdr_int): Add fall-through comment.
	(xdr_u_int): Likewise.
	(xdr_enum): Likewise.
	(xdr_bytes): Reword fall-through comment.
	(xdr_string): Likewise.
