c3ce62cc0b Declare some TS 18661-4 interfaces for C2X.
C2X (current version in git, postdating the most recent public draft
available as a PDF on the WG14 website) adds the interfaces from TS
18661-4, other than the reduction functions, as unconditionally
required and visible in <math.h> for hosted implementations; the
__STDC_WANT_IEC_60559_FUNCS_EXT__ macro is not included in C2X at all
(as the reduction functions aren't included at all, expected to end up
in a version of the TS updated to be relative to C2X).

This patch updates the glibc headers accordingly, following the same
pattern used for 18661-1 functions.  As the only 18661-4 functions
currently supported are the exp10 functions that have been in glibc
for a very long time, this means that in fact __GLIBC_USE
(IEC_60559_FUNCS_EXT) ends up being used only to determine the
definition of __GLIBC_USE_IEC_60559_FUNCS_EXT_C2X, not yet in any
headers other than bits/libc-header-start.h.

(I hope to add the other 18661-4 functions to glibc at some point; the
main complication is the current lack of MPFR support for many of
these functions.)

Tested for x86_64.

	Update comment.

0175c9e9be Declare most TS 18661-1 interfaces for C2X.
C2X adds the interfaces from TS 18661-1, and all except a handful in
Annex F are unconditionally visible in C2X rather than only visible
when __STDC_WANT_IEC_60559_BFP_EXT__ is defined.  This patch updates
glibc headers accordingly: most uses of __GLIBC_USE
(IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE
(IEC_60559_BFP_EXT_C2X).  (Regarding totalorder and totalordermag, the
type-generic macros in tgmath.h will go away when the functions are
changed to take pointer arguments.)

777d75fbc0 Add feature test macro _ISOC2X_SOURCE.
This patch starts preparation for C2X support in glibc headers by
adding a feature test macro _ISOC2X_SOURCE and corresponding
__GLIBC_USE (ISOC2X).  (I chose to use the newer __GLIBC_USE style for
this rather than the older __USE_* macros tested with #ifdef.)  As
with other such macros, C2X features are also enabled by compiling for
a standard newer than C17, or by using _GNU_SOURCE.

This patch does not itself enable anything new in the headers for C2X;
that is to be done in followup patches.  (For example, most of the TS
18661-1 functions should be declared for C2X without any
__STDC_WANT_IEC_60559_BFP_EXT__ being needed, but the ones that
18661-1 adds to Annex F because of their close relation to IEEE 754
formats do still need the WANT macro in C2X.)

Once C2X becomes an actual standard we'll presumably move to using the
actual year in the feature test macro and __GLIBC_USE, with some
period when both macro spellings are accepted, as was done with
_ISOC9X_SOURCE.

Tested for x86_64.

	* include/features.h (_ISOC2X_SOURCE): New feature test macro.
	Undefine and define to 1 if [_GNU_SOURCE].
	(__GLIBC_USE_ISOC2X): New macro.  Undefine and redefine depending
	on [_ISOC2X_SOURCE] and [__STDC_VERSION__ > 201710L].
	(__USE_ISOC11): Also define to 1 if [_ISOC2X_SOURCE].
	(__USE_ISOC99): Likewise.
	(__USE_ISOC95): Likewise.
	* manual/creature.texi (_ISOC2X_SOURCE): Document.

9b9670fcd8 elf: Support elf/tst-dlopen-aout in more configurations
dlopen can no longer open PIE binaries, so it is not necessary
to link the executable as non-PIE to trigger a dlopen failure.

If we hard-code the path to the real executable, we can run the test
with and without hard-coded paths because the dlopen path will not
be recognized as the main program in both cases.  (With an explict
loader invocation, the loader currently adds argv[0] to l_libname
for the main map and the dlopen call suceeds as a result; it does
not do that in standard mode.)

b6d2c4475d malloc: Fix missing accounting of top chunk in malloc_info [BZ #24026]
Fixes `<total type="rest" size="..."> incorrectly showing as 0 most
of the time.

The rest value being wrong is significant because to compute the
actual amount of memory handed out via malloc, the user must subtract
it from <system type="current" size="...">. That result being wrong
makes investigating memory fragmentation issues like
<https://bugzilla.redhat.com/show_bug.cgi?id=843478> close to
impossible.

0bfddfc944 iconv: Revert steps array reference counting changes
The changes introduce a memory leak for gconv steps arrays whose
first element is an internal conversion, which has a fixed
reference count which is not decremented.  As a result, after the
change in commit 50ce3eae5b, the steps
array is never freed, resulting in an unbounded memory leak.

This reverts commit 50ce3eae5b
("gconv: Check reference count in __gconv_release_cache
[BZ #24677]") and commit 7e740ab2e7
("libio: Fix gconv-related memory leak [BZ #24583]").  It

The address itself is used in a check in the caller, so using

50ce3eae5b gconv: Check reference count in __gconv_release_cache [BZ #24677]
This fixes a regression introduced in commit
7e740ab2e7 ("libio: Fix gconv-related
memory leak [BZ #24583]").

__gconv_release_cache is only ever called with heap-allocated
arrays which contain at least one member.  The statically allocated
ASCII steps are filtered out by __wcsmbs_close_conv.

7e681561a3 x86-64: Compile branred.c with -mprefer-vector-width=128 [BZ #24603]
When compiled with -O3 and AVX, GCC 8 and 9 optimize some loops in
sysdeps/ieee754/dbl-64/branred.c with 256-bit vector instructions,
which leads to store forward stall:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90579

There is no easy fix in compiler.  This patch limits vector width to
128 bits to work around this issue.  It improves performance of sin
and cos by more than 40% on Skylake compiled with -O3 -march=skylake.

Tested with GCC 7/8/9 on x86-64.

	[BZ #24603]
	* sysdeps/x86_64/configure.ac: Check if -mprefer-vector-width=128
	works.
	* sysdeps/x86_64/configure: Regenerated.
	* sysdeps/x86_64/fpu/Makefile (CFLAGS-branred.c): New.  Set
	to -mprefer-vector-width=128 if supported.

7854ebf8ed Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]
The kernel changes for a 64-bit time_t on 32-bit architectures
resulted in <asm/socket.h> indirectly including <linux/posix_types.h>.
The latter is not namespace-clean for the POSIX version of
<sys/socket.h>.

This issue has persisted across several Linux releases, so this commit
creates our own copy of the SO_* definitions for !__USE_MISC mode.

The new test socket/tst-socket-consts ensures that the copy is
consistent with the kernel definitions (which vary across
architectures).  The test is tricky to get right because CPPFLAGS
includes include/libc-symbols.h, which in turn defines _GNU_SOURCE
unconditionally.

Tested with build-many-glibcs.py.  I verified that a discrepancy in
the definitions actually results in a failure of the
socket/tst-socket-consts test.

35e038c1d2 test-container: Install with $(all-subdirs) [BZ #24794]
Whenever a sub-make is created, it inherits the variable subdirs from its
parent.  This is also true when make check is called with a restricted
list of subdirs.  In this scenario, make install is executed "partially"
and testroot.pristine ends up with an incomplete installation.

95da14dac0 test-container: Avoid copying unintended system libraries
Some DSOs are distributed in hardware capability directories, e.g.
/usr/lib64/power7/libc.so.6
Whenever the processor is able to use one of these hardware-enabled
DSOs, testroot.pristine ends up with copies of glibc-provided libraries
from the system because it can't overwrite or remove them.

This patch avoids the unintended copies by executing ld.so with the same
arguments passed to each glibc test.

	* Makefile (testroot.pristine/install.stamp): Execute ld.so with
	the same arguments used in all tests.

4a8f6d3155 nptl: Remove unnecessary forwarding of pthread_cond_clockwait from libc
In afe4de7d28, I added forwarding functions
from libc to libpthread for __pthread_cond_clockwait and
pthread_cond_clockwait to mirror those for pthread_cond_timedwait. These
are unnecessary[1], since these functions aren't (yet) being called from
within libc itself. Let's remove them.

      * nptl/forward.c: Remove unnecessary __pthread_cond_clockwait and
	pthread_cond_clockwait forwarding functions.  There are no internal
	users, so it is unnecessary to expose these functions in libc.so.
	* sysdeps/nptl/pthread-functions.h (pthread_functions): Remove
	unnecessary ptr___pthread_cond_clockwait member.
	* nptl/nptl-init.c (pthread_functions): Remove assignment of
	removed member.

9208c3b804 Afar locales: Months and days updated from CLDR (bug 21897).
This commit updates month and weekday names (full and abbreviated)
from CLDR 35.1 with the following exceptions.

It was not clear why the full name of February in aa_DJ and aa_ER was
"Kudo" while the abbreviated version is "Nah" but some additional
sources [1] [2] as well as the content of aa_ER and aa_ER@saaho
suggest it should be "Naharsi Kudo".  This commit consequently sets
the translation of February to "Naharsi Kudo" in aa_DJ and aa_ET.

aa_ER@saaho is not supported by CLDR but since the month names were
identical to aa_ER before this commit, the same values have been copied
from aa_ER.
