libpthread_nonshared.a is unused after this, so remove it from the
build.
There is no ABI impact because pthread_atfork was implemented using
__register_atfork in libc even before this change.
pthread_atfork has to be a weak alias because pthread_* names are not
reserved in libc.

As discussed in bug 22902, the i386 fenv_private.h implementation has
problems for float128 for the case of 32-bit glibc built with libgcc
from GCC configured using --with-fpmath=sse.
The optimized floating-point state handling in fenv_private.h needs to
know which floating-point state - x87 or SSE - is used for each
floating-point type, so that only one state needs updating / testing
for libm code using that state internally. On 32-bit x86, the x87
rounding mode is always used for float128, but the x87 exception flags
are only used when libgcc is built using x87 floating-point
arithmetic; if libgcc is built for SSE arithmetic, the SSE exception
flags are used.
The choice of arithmetic with which libgcc is built is independent of
that with which glibc is built. Thus, since glibc cannot tell the
choice used in libgcc, the default implementations of
libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128 (which
use the <fenv.h> functions, thus using both x87 and SSE state on
processors that have both) need to be used; this patch updates the
code accordingly.
Tested for 32-bit x86; HJ reports testing in the --with-fpmath=sse
case.

On sparc, localplt test failures appear when building with -Os because
of a call to strtoumax from
sysdeps/unix/sysv/linux/sparc/sparc64/get_clockfreq.c, and strtoumax
is not inlined when building with -Os. This patch fixes those
failures by using libc_hidden_proto and libc_hidden_def for strtoumax.
Tested with build-many-glibcs.py for
sparc64-linux-gnu-disable-multi-arch, sparc64-linux-gnu,
sparcv9-linux-gnu-disable-multi-arch, sparcv9-linux-gnu that this
fixes that test failure with -Os.

Continuing fixes for -Os build issues shown with build-many-glibcs.py,
this patch adds uses of DIAG_* to disable -Wmaybe-uninitialized in two
more places where code inlined from strcoll / wcscoll is wrongly
diagnosed as possibly using uninitialized structure fields. (All
these warnings in different places for these functions are I think
essentially the same bug.)
Tested with build-many-glibcs.py for alpha-linux-gnu and
mips-linux-gnu that this fixes the -Os build failures for those
configurations with GCC 7.
* locale/weightwc.h (findidx): Ignore -Wmaybe-uninitialized for
-Os in two more places.

These lines don’t yet work because of a glibc bug, not because of
problems in the locale data. No matter what sorting rules one uses,
these characters cannot be sorted at all at the moment.
As soon as that bug is fixed, these lines should be added back to the
test file.
* localedata/cmn_TW.UTF-8.in: Remove the lines which cannot
be sorted correctly at the moment because of a bug.

Therefore, using [a-z] does not make much sense except in the C/POSIX locale.
The new iso14651_t1_common lists upper case and lower case Latin characters
in a different order than the old one which causes surprising results
for example in the de_DE locale: [a-z] now includes A because A comes
after a in iso14651_t1_common but does not include Z because that comes
after z in iso14651_t1_common.

This test case tests how many collating elements are defined in
da_DK.ISO-8859-1 locale. The da_DK locale source defines 4:
collating-element <A-A> from "<U0041><U0041>"
collating-element <A-a> from "<U0041><U0061>"
collating-element <a-A> from "<U0061><U0041>"
collating-element <a-a> from "<U0061><U0061>"
The new iso14651_t1_common file defines more collating elements, two
of them are in the ISO-8859-1 range:
collating-element <U004C_00B7> from "<U004C><U00B7>" % decomposition of LATIN CAPITAL LETTER L WITH MIDDLE DOT
collating-element <U006C_00B7> from "<U006C><U00B7>" % decomposition of LATIN SMALL LETTER L WITH MIDDLE DOT
So the total count is now 6 instead of 4.
* posix/bug-regex5.c: Fix test case because with the new
iso14651_t1_common file, the da_DK locale now has 6 collating elements
in the ISO-8859-1 range instead of 4 with the old iso14651_t1_common
file.

are ignorable on all 4 levels
Entries for characters which have “IGNORE” on all 4 levels like:
<U0001> IGNORE;IGNORE;IGNORE;IGNORE % START OF HEADING (in ISO 6429)
are changed into:
<U0001> IGNORE;IGNORE;IGNORE;<U0001> % START OF HEADING (in ISO 6429)
i.e. putting the code point of the character into the fourth level
instead of “IGNORE”. Without that change, all such characters
would compare equal which would make a wcscoll test case fail.
It is better to have a clearly defined sort order even for characters
like this so it is good to use the code point as a tie-break.

[BZ #14095] - Review / update collation data from Unicode / ISO 14651
File downloaded from:
http://standards.iso.org/iso-iec/14651/ed-4/ISO14651_2016_TABLE1_en.txt
Updating this file alone is not enough, there are problems in the new
file which need to be fixed and the collation rules for many locales
need to be adapted. This is done by the following patches.
This update also fixes the problem that many characters are treated as
identical when sorting because they were not yet in the old
iso14651_t1_common file, see:
https://bugzilla.redhat.com/show_bug.cgi?id=1336308

While there are now clean -Os build and test results on x86_64 (given
my patch <https://sourceware.org/ml/libc-alpha/2018-02/msg00602.html>,
pending review), testing with -Os with build-many-glibcs.py shows the
build is still failing with -Os everywhere except for x86_64, x86 and
s390x.
There are a variety of different build failures, but the most common
seem to be in strcoll / wcscoll, similar to existing such cases where
DIAG_* are used to disable -Wmaybe-uninitialized. There are various
different failures even within those functions. This patch fixes one
particular case that seems quite common, where the warning appears at
the declarations of seq1 and seq2.
Tested with build-many-glibcs.py that this fixes the -Os build for
aarch64-linux-gnu with GCC 7.
* string/strcoll_l.c: Include <libc-diag.h>.

Glibc build generates header files to define constants from special .sym
files. If a .sym file includes the same header file which it generates,
it leads to circular dependency which may lead to build hang on a
many-core machine. Define GEN_AS_CONST_HEADERS when generating header
files to avoid circular dependency.
<tcb-offsets.h> is needed for i686 and it isn't needed for x86-64 at
least since glibc 2.23.

LC_TIME in these 4 locales is identical, using “copy "es_BO"” makes
that more obvious.

Current implementation (sysdeps/nptl/fork.c) replicates the atfork
handlers list backward to invoke the child handlers after fork/clone
syscall.
The internal atfork handlers is implemented as a single-linked list
so a lock-free algorithm can be used, trading fork mulithread call
performance for some code complexity and dynamic stack allocation
(since the backwards list should not fail).
This patch refactor it to use a dynarary instead of a linked list.
It simplifies the external variables need to be exported and also
the internal atfork handler member definition.
The downside is a serialization of fork call in multithread, since to
operate on the dynarray the internal lock should be used. However
as noted by Florian, it already acquires external locks for malloc
and libio so it is already hitting some lock contention. Besides,
posix_spawn should be faster and more scalable to run external programs
in multithread environments.
Checked on x86_64-linux-gnu.

This patch renames the nptl-signals.h header to internal-signals.h.
On Linux the definitions and functions are not only NPTL related, but
used for other POSIX definitions as well (for instance SIGTIMER for
posix times, SIGSETXID for id functions, and signal block/restore
helpers) and since generic functions will be places and used in generic
implementation it makes more sense to decouple it from NPTL.
Checked on x86_64-linux-gnu.
* sysdeps/nptl/nptl-signals.h: Move to ...
* sysdeps/generic/internal-signals.h: ... here. Adjust internal
comments.
* sysdeps/unix/sysv/linux/internal-signals.h: Add include guards.

After regenerating ULPs from scratch in
commit 8e7196c8759287a3e4c882e3c7cf32ddc322df8a, I've missed
to test it with multiple gcc versions. Hence, here is a further update.
ChangeLog:
* sysdeps/s390/fpu/libm-test-ulps: Regenerated.

This patch eliminates a number of #if 0 and #ifdef TODO blocks, macros
that are never used, macros that provide portability to substrates that
lack basic things like EINVAL and off_t, and other such debris.
I preserved IO_DEBUG and CHECK_FILE, even though as far as I can tell
IO_DEBUG is never defined and therefore CHECK_FILE never does
anything, because it seems like we might actually want to turn it _on_.
Installed stripped libraries and executables are unchanged, except,
again, that the line number of an assertion changes (this time it's
somewhere in fileops.c).
* libio/libio.h (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust):
Define here, unconditionally.
* libio/iolibio.h (_IO_pos_BAD): Don't define here.
* libio/libioP.h: Remove #if 0 blocks.
(_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Don't define here.
(_IO_va_start, COERCE_FILE, MAYBE_SET_EINVAL): Don't define.
(CHECK_FILE): Don't use MAYBE_SET_EINVAL or COERCE_FILE. Fix style.
* libio/clearerr.c, libio/fputc.c, libio/getchar.c:
Assume weak_alias is always defined.
* libio/fileops.c, libio/genops.c, libio/oldfileops.c
* libio/oldpclose.c, libio/pclose.c, libio/wfileops.c:
Remove #if 0 and #ifdef TODO blocks.
Assume text_set_element is always defined.
* libio/iofdopen.c, libio/iogetdelim.c, libio/oldiofdopen.c
Use __set_errno (EINVAL) instead of MAYBE_SET_EINVAL.
* libio/tst-mmap-eofsync.c: Make #if 1 block unconditional.

This entirely mechanical (except for some indentation fixups) patch
replaces all uses of _IO_file_flags with _flags and removes the #define.
Installed stripped libraries and executables are unchanged by this patch.

All uses changed to _flags.

This patch eliminates the "compatibility defines"
_IO_UNIFIED_JUMPTABLES (always defined to 1, used in a number of #ifs
which are therefore always false), _STDIO_USES_IOSTREAM (unused),
__HAVE_COLUMN (unused), _IO_BE (replaced with __glibc_unlikely), and
yet another redundant definition of EOF.
Installed stripped libraries are unchanged by this patch.
* libio/libio.h (_IO_UNIFIED_JUMPTABLES, _STDIO_USES_IOSTREAM)
(__HAVE_COLUMN, _IO_BE): Don't define.
(_IO_peekc_unlocked, _IO_getwc_unlocked, _IO_putwc_unlocked)
(_IO_fwide_maybe_incompatible): Use __glibc_unlikely.
* libio/libioP.h (EOF): Don't define.
* libio/iofdopen.c, libio/iofopen.c, libio/iopopen.c
* libio/iovdprintf.c, libio/oldiofdopen.c, libio/oldiofopen.c
* libio/oldiopopen.c, debug/vdprintf_chk.c: Remove #if block
testing _IO_UNIFIED_JUMPTABLES.

This patch mechanically removes all remaining uses, and the
definitions, of the following libio name aliases:
name replaced with
---- -------------
_IO_FILE FILE
_IO_fpos_t __fpos_t
_IO_fpos64_t __fpos64_t
_IO_size_t size_t
_IO_ssize_t ssize_t or __ssize_t
_IO_off_t off_t
_IO_off64_t off64_t
_IO_pid_t pid_t
_IO_uid_t uid_t
_IO_wint_t wint_t
_IO_va_list va_list or __gnuc_va_list
_IO_BUFSIZ BUFSIZ
_IO_cookie_io_functions_t cookie_io_functions_t
__io_read_fn cookie_read_function_t
__io_write_fn cookie_write_function_t
__io_seek_fn cookie_seek_function_t
__io_close_fn cookie_close_function_t
I used __fpos_t and __fpos64_t instead of fpos_t and fpos64_t because
the definitions of fpos_t and fpos64_t depend on the largefile mode.
I used __ssize_t and __gnuc_va_list in a handful of headers where
namespace cleanliness might be relevant even though they're
internal-use-only. In all other cases, I used the public-namespace
name.
There are a tiny handful of places where I left a use of 'struct _IO_FILE'
alone, because it was being used together with 'struct _IO_FILE_plus'
or 'struct _IO_FILE_complete' in the same arithmetic expression.
Because this patch was almost entirely done with search and replace, I
may have introduced indentation botches. I did proofread the diff,
but I may have missed something.
The ChangeLog below calls out all of the places where this was not a
pure search-and-replace change.
Installed stripped libraries and executables are unchanged by this patch,
except that some assertions in vfscanf.c change line numbers.
* libio/libio.h (_IO_FILE): Delete; all uses changed to FILE.
(_IO_fpos_t): Delete; all uses changed to __fpos_t.
(_IO_fpos64_t): Delete; all uses changed to __fpos64_t.
(_IO_size_t): Delete; all uses changed to size_t.

(_IO_off_t): Delete; all uses changed to off_t.
(_IO_off64_t): Delete; all uses changed to off64_t.
(_IO_pid_t): Delete; all uses changed to pid_t.
(_IO_uid_t): Delete; all uses changed to uid_t.
(_IO_wint_t): Delete; all uses changed to wint_t.
(_IO_va_list): Delete; all uses changed to va_list or __gnuc_va_list.
(_IO_BUFSIZ): Delete; all uses changed to BUFSIZ.
(_IO_cookie_io_functions_t): Delete; all uses changed to
cookie_io_functions_t.
(__io_read_fn): Delete; all uses changed to cookie_read_function_t.
(__io_write_fn): Delete; all uses changed to cookie_write_function_t.
(__io_seek_fn): Delete; all uses changed to cookie_seek_function_t.
(__io_close_fn): Delete: all uses changed to cookie_close_function_t.
* libio/iofopncook.c: Remove unnecessary forward declarations.
* libio/iolibio.h: Correct outdated commentary.

As requested by Adhemerval, this patch removes some preprocessor
conditionals from the libio headers that were only relevant when
building libio outside glibc.
Installed stripped libraries and executables are unchanged by this
patch.
* libio/iolibio.h, libio/libioP.h: Remove extern "C".
* libio/libio.h: Remove __BEGIN_DECLS and __END_DECLS.
Remove preprocessor conditionals on _LIBC and __USE_GNU,
which are always true, and __cplusplus, which is always false.

15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for putc_unlocked and fputc_unlocked.
libc_hidden_* are used for both functions, while namespace issues are
addressed by making putc_unlocked a weak alias of hidden
__putc_unlocked, which is called in the one place where namespace
issues arise (and defined as an inline function in include/stdio.h).
Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved). This completes fixing the -Os
linknamespace failures (at least for x86_64); localplt failures remain
after this patch.

* include/stdio.h [!_ISOMAC] (fputc_unlocked): Use
libc_hidden_proto.
[!_ISOMAC] (putc_unlocked): Likewise.
[!_ISOMAC] (__putc_unlocked): Declare as hidden function, and

Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for getc_unlocked.
__getc_unlocked already exists; this patch makes it explicitly hidden,
calls it where needed for namespace reasons, adds an inline function
for it when inline functions are used and adds libc_hidden_proto /
libc_hidden_weak for getc_unlocked.
Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved). Because of other such failures
that remain after this patch, neither of the bugs can yet be closed.

* misc/getttyent.c (__getttyent): Call __getc_unlocked instead of
getc_unlocked.
