This patch adds full support for cross-building benchmarks. Some
benchmarks like those that need locales to be generated cannot be
built and are hence skipped for cross builds.
Tested by cross building for aarch64 on x86_64 and then running the
generated benchmark on aarch64.
* benchtests/Makefile (wcsmbs-benchset): Include only for
native builds and runs.
(LOCALES): Likewise.
(bench-build): Build timing-type here instead of the bench
target. Generate locale only for native builds.
* benchtests/README: Add note for cross-building.
For situations where we are cross-building or where we want to avoid
building on the target system, we want a way to only build benchmarks
and then copy them over to the target system to run them. I have also
added a simple enhancement for the 'bench' target where all benchmark
binaries are built and then the benchmarks executed.
Tested on arm.
Makefile.in (bench-build): New target.
Rules (PHONY): Add bench-build target.
benchtests/Makefile (bench): Depend on bench-build.
(bench-build): New target.
A bunch of locales were copying the wrong source locale -- looks like they
were basically TODOs from the original imports. This lead to bad values
for int_prefix for them.
The newer version of the standard adds %C %e %t to tel_int_fmt and
tel_dom_fmt. Make sure localedef accepts them.
Also change the default tel_int_fmt to include %t per the standard.
Very few locales set audience/application/abbreviation, and
even the ones that do, set them largely to default/useless
values. Drop them from the few locales until we decide we
want to set these everywhere (to something useful).
This updates a few locales based on CLDR v29 data. I've verified most by
hand while the rest I know are correct.
For int_curr_symbol, it should be 3 characters followed by a space:
ar_SS: changing SDG to SSP
bem_ZM: changing ZMK to ZMW
dz_BT: changing BTN to BTN # Just changing " " to "<U0020>".
en_ZW: changing ZWD to USD
es_SV: changing SVC to USD
lv_LV: changing LVL to EUR
ne_NP: changing INR to NPR
pap_AW: changing ANG to AWG
the_NP: changing INR to NPR
Some of these require updates iso-4217.def.
For currency_symbol, it should be the standard/localized symbol name:

Note: Some of the characters might not render as they're still quite new
in the Unicode database.
Currently localedef accepts any value for the category keyword. This has
allowed bad values to propagate to the vast majority of locales (~90%).
Add some logic to only accept a few standards.
The ISO 30112 standard defines the valid values for the category
keyword as only a few options:
posix:1993
i18n:2004
i18n:2012
The vast majority of locales had changed the "i18n" string to the
name of its own locale (e.g. "ak_GH:2013") as well as tweaking the
date (presumably thinking it should be the date of submission).
Convert all of them to "i18n:2012" for consistency. A follow up
change will update localedef to actually check/validate the field.
Updated from the model numbers of Goldmont and Airmont processors in

This updates a bunch of locales based on CLDR v29 data:

yi_US: changing די פֿאראײניקטע שטאַטן to פֿאַראייניגטע שטאַטן
yo_NG: changing Nigeria to Orílẹ́ède Nàìjíríà
yue_HK: changing 香港 to 中華人民共和國香港特別行政區
zu_ZA: changing Mzansi Afrika to i-South Africa
These all look largely straightforward. Many had English translations
instead of native, and a few have been updated. I can't verify some of
them as I'm not personally familiar, but the CLDR data matches.
The USA->United States seems a little odd, but that is also what the
CLDR database uses everywhere (rather than "United States of America").
We can also fill in a country name where there wasn't one before.
Many look correct to me (mostly the English ones), but there's also
many that I have no idea. But it can't be worse than leaving it
blank ? :)

There are only two page sizes that locales use: US-Letter and A4.
For the former, move to copying the en_US locale, while for the
latter, move to copying the i18n locale. This lets us clean up
all the stray comments like FIXME.
There should be no functional differences here.
This patch fixes the __ALIGNMENT_{ARG,COUNT} definition for ports that
define __ASSUME_ALIGNED_REGISTER_PAIRS by including the kernel-features.h
(where it is defined if the case).

* sysdeps/unix/sysv/linux/sysdep.h: Include kernel-features.h.
The commit 985fc132f2
"strfmon_l: Use specified locale for number formatting [BZ #19633]"
introduced an elf/check-abi-libc testfailure due to __printf_fp_l
on architectures which use sysdeps/ieee754/ldbl-opt/math_ldbl_opt.h.
This patch uses libc_hidden_def instead of ldbl_hidden_def.
The ldbl_strong_alias is removed due to the rename of ___printf_fp_l
to __printf_fp_l.
ChangeLog:
* stdio-common/printf_fp.c (__printf_fp_l):
Rename ___printf_fp_l to __printf_fp_l and
remove strong alias. Use libc_hidden_def instead
of ldbl_hidden_def macro.
The fork handler now runs so late that there is no risk anymore that
other fork handlers in the same thread use malloc, so it is no
longer necessary to install malloc hooks which made a subset
of malloc functionality available to the thread that called fork.
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.
The overloading approach in the W* macros was incompatible with
integer expressions of a type different from int. Applications
using union wait and these macros will have to migrate to the
POSIX-specified int status type.
There are only two measurement systems that locales use: US and metric.
For the former, move to copying the en_US locale, while for the latter,
move to copying the i18n locale. This lets us clean up all the stray
comments like FIXME.
There should be no functional differences here.

There's no real value in populating this field when it's the same as the
default POSIX setting, so drop it from most locales so it's clear what's
going on.
The large memcpy micro benchmark in glibc shows that there is a
regression with large data on Haswell machine. non-temporal store in
memcpy on large data can improve performance significantly. This
patch adds a threshold to use non temporal store which is 6 times of
shared cache size. When size is above the threshold, non temporal
store will be used, but avoid non-temporal store if there is overlap
between destination and source since destination may be in cache when
source is loaded.
For size below 8 vector register width, we load all data into registers
and store them together. Only forward and backward loops, which move 4
vector registers at a time, are used to support overlapping addresses.
For forward loop, we load the last 4 vector register width of data and
the first vector register width of data into vector registers before the
loop and store them after the loop. For backward loop, we load the first
4 vector register width of data and the last vector register width of
data into vector registers before the loop and store them after the loop.

This patch adds support for using the implementations of gettimeofday()
and clock_gettime() provided by the kernel in the VDSO. The VDSO will
always provide clock_gettime() as CLOCK_{REALTIME,MONOTONIC}_COARSE can
be implemented regardless of platform. CLOCK_{REALTIME,MONOTONIC}, along
with gettimeofday(), are only implemented on platforms which make use of
either the CP0 count or GIC as their clocksource. On other platforms,
the VDSO does not provide the __vdso_gettimeofday symbol, as it is
never useful.
The VDSO functions return ENOSYS when they encounter an unsupported
request, in which case glibc should fall back to the standard syscall.
Tested with upstream kernel 4.5 and QEMU emulating Malta.

This patch consolidates all the pwrite/pwrite64 implementation for Linux
in only one (sysdeps/unix/sysv/linux/pwrite{64}.c). It also removes the
syscall from the auto-generation using assembly macros.
For pwrite{64} offset argument placement the new SYSCALL_LL{64} macro
is used. For pwrite ports that do not define __NR_pwrite will use
__NR_pwrite64 and for pwrite64 ports that dot define __NR_pwrite64 will
use __NR_pwrite for the syscall.
Checked on x86_64, x32, i386, aarch64, and ppc64le.

This patch consolidates all the pread/pread64 implementation for Linux
in only one (sysdeps/unix/sysv/linux/pread.c). It also removes the
syscall from the auto-generation using assembly macros.
For pread{64} offset argument placement the new SYSCALL_LL{64} macro
is used. For pread ports that do not define __NR_pread will use
__NR_pread64 and for pread64 ports that dot define __NR_pread64 will
use __NR_pread for the syscall.
Checked on x86_64, x32, i386, aarch64, and ppc64le.

This patch add three new macros (SYSCALL_LL, SYSCALL_LL64, and
__ASSUME_WORDSIZE64_ILP32) to use along with off_t and off64_t argument
syscalls. The rationale for this change is:
1. Remove multiple implementations for the same syscall for different
architectures (for instance, pread have 6 different implementations).
2. Also remove the requirement to use syscall wrappers for cancellable
entrypoints.
The macro usage should be used along __ALIGNMENT_ARG to follow ABI constrains
for architecture where it applies. For instance, pread can be rewritten as:
return SYSCALL_CANCEL (pread, fd, buf, count,
__ALIGNMENT_ARG SYSCALL_LL (offset));
Another macro, SYSCALL_LL64, is provided for off64_t. The macro
__ASSUME_WORDSIZE64_ILP32 is used by the ABI to define is uses 64-bit register
even if ABI is ILP32 (for instance x32 and mips64-n32).
The changes itself are not currently used in any implementation, so no
code change is expected.

This patch defines __ASSUME_ALIGNED_REGISTER_PAIRS for the missing
ports that require 64-bit value (e.g., long long) to be aligned to
an even register pair in argument passing.
