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 ? :) ar_AE: changing to الإمارات العربية المتحدة ar_BH: changing to البحرين ar_DZ: changing to الجزائر ar_EG: changing to مصر ar_IN: changing to الهند ar_IQ: changing to العراق ar_JO: changing to الأردن ar_KW: changing to الكويت ar_LB: changing to لبنان ar_LY: changing to ليبيا ar_MA: changing to المغرب ar_OM: changing to عُمان ar_QA: changing to قطر ar_SA: changing to المملكة العربية السعودية ar_SD: changing to السودان ar_SS: changing to جنوب السودان ar_SY: changing to سوريا ar_TN: changing to تونس ar_YE: changing to اليمن as_IN: changing to ভাৰত ast_ES: changing to España az_AZ: changing to Azərbaycan be_BY: changing to Беларусь bn_IN: changing to ভারত br_FR: changing to Frañs brx_IN: changing to भारत bs_BA: changing to Bosna i Hercegovina ca_AD: changing to Andorra ca_ES: changing to Espanya ca_FR: changing to França ca_IT: changing to Itàlia ce_RU: changing to Росси da_DK: changing to Danmark de_AT: changing to Österreich de_BE: changing to Belgien de_CH: changing to Schweiz de_LU: changing to Luxemburg el_CY: changing to Κύπρος el_GR: changing to Ελλάδα en_AG: changing to Antigua & Barbuda en_AU: changing to Australia en_BW: changing to Botswana en_CA: changing to Canada en_DK: changing to Denmark en_GB: changing to United Kingdom en_HK: changing to Hong Kong SAR China en_IE: changing to Ireland en_IN: changing to India en_NZ: changing to New Zealand en_PH: changing to Philippines en_SG: changing to Singapore en_ZW: changing to Zimbabwe es_AR: changing to Argentina es_BO: changing to Bolivia es_CL: changing to Chile es_CO: changing to Colombia es_CU: changing to Cuba es_DO: changing to República Dominicana es_EC: changing to Ecuador es_ES: changing to España es_GT: changing to Guatemala es_HN: changing to Honduras es_MX: changing to México es_NI: changing to Nicaragua es_PA: changing to Panamá es_PE: changing to Perú es_PR: changing to Puerto Rico es_PY: changing to Paraguay es_SV: changing to El Salvador es_UY: changing to Uruguay es_VE: changing to Venezuela eu_ES: changing to Espainia fil_PH: changing to Pilipinas fo_FO: changing to Føroyar fr_BE: changing to Belgique fr_CA: changing to Canada fr_CH: changing to Suisse fr_FR: changing to France fr_LU: changing to Luxembourg fur_IT: changing to Italie fy_DE: changing to Dútslân fy_NL: changing to Nederlân ga_IE: changing to Éire gl_ES: changing to España gu_IN: changing to ભારત gv_GB: changing to Rywvaneth Unys he_IL: changing to ישראל hi_IN: changing to भारत hr_HR: changing to Hrvatska hu_HU: changing to Magyarország id_ID: changing to Indonesia is_IS: changing to Ísland it_CH: changing to Svizzera it_IT: changing to Italia ja_JP: changing to 日本 ka_GE: changing to საქართველო kk_KZ: changing to Қазақстан kl_GL: changing to Kalaallit Nunaat kn_IN: changing to ಭಾರತ kok_IN: changing to भारत ko_KR: changing to 대한민국 ks_IN: changing to ہِنٛدوستان ks_IN@devanagari: changing to भारत kw_GB: changing to Rywvaneth Unys ky_KG: changing to Кыргызстан lt_LT: changing to Lietuva lv_LV: changing to Latvija mg_MG: changing to Madagasikara ml_IN: changing to ഇന്ത്യ mr_IN: changing to भारत ms_MY: changing to Malaysia mt_MT: changing to Malta nb_NO: changing to Norge ne_NP: changing to नेपाल nl_AW: changing to Aruba nl_BE: changing to België nl_NL: changing to Nederland nn_NO: changing to Noreg or_IN: changing to ଭାରତ os_RU: changing to Уӕрӕсе pa_IN: changing to ਭਾਰਤ pa_PK: changing to ਪਾਕਿਸਤਾਨ pl_PL: changing to Polska pt_BR: changing to Brasil pt_PT: changing to Portugal ru_RU: changing to Россия ru_UA: changing to Украина sd_IN@devanagari: changing to भारत se_NO: changing to Norga si_LK: changing to ශ්‍රී ලංකාව sk_SK: changing to Slovensko sl_SI: changing to Slovenija sq_AL: changing to Shqipëri sv_SE: changing to Sverige ta_IN: changing to இந்தியா ta_LK: changing to இலங்கை ur_IN: changing to بھارت ur_PK: changing to پاکستان

* localedata: LC_PAPER: use copy directives everywhereMike Frysinger2016-04-15168-560/+337
| | | | | | | | | 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.

* Fix strfmon_l: Use specified locale for number formatting [BZ #19633]Stefan Liebler2016-04-142-6/+12
| | | | | | | | | | | | | | | | | | The commit 985fc132f23dbb83de76c5af9e783ef1b5900148 "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.
* malloc: Remove malloc hooks from fork handlerFlorian Weimer2016-04-143-119/+25
| | | | | | | 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.

* malloc: Run fork handler as late as possible [BZ #19431]Florian Weimer2016-04-149-51/+321
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Remove union wait [BZ #19613]Florian Weimer2016-04-1417-199/+72
| | | | | | | 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.

* X86-64: Use non-temporal store in memcpy on large dataH.J. Lu2016-04-126-171/+260
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. [BZ #19928] * sysdeps/x86_64/cacheinfo.c (__x86_shared_non_temporal_threshold): New. (init_cacheinfo): Set __x86_shared_non_temporal_threshold to 6 times of shared cache size. * sysdeps/x86_64/multiarch/memmove-avx-unaligned-erms.S (VMOVNT): New. * sysdeps/x86_64/multiarch/memmove-avx512-unaligned-erms.S (VMOVNT): Likewise. * sysdeps/x86_64/multiarch/memmove-sse2-unaligned-erms.S (VMOVNT): Likewise.

Rewrite to use forward and backward loops, which move 4 vector registers at a time, to support overlapping addresses and use non temporal store if size is above the threshold and there is no overlap between destination and source.
* VDSO support for MIPSMatthew Fortune2016-04-128-0/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. ./vdsotest gettimeofday bench gettimeofday: syscall: 1021 nsec/call gettimeofday: libc: 262 nsec/call gettimeofday: vdso: 174 nsec/call * sysdeps/unix/sysv/linux/mips/Makefile (sysdep_routines): Include dl-vdso. * sysdeps/unix/sysv/linux/mips/Versions: Add __vdso_clock_gettime. * sysdeps/unix/sysv/linux/mips/init-first.c: New file. * sysdeps/unix/sysv/linux/mips/libc-vdso.h: New file. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h: (INTERNAL_VSYSCALL_CALL): Define to be compatible with MIPS definitions of INTERNAL_SYSCALL_{ERROR_P,ERRNO}.

* Consolidate pwrite/pwrite64 implementationsAdhemerval Zanella2016-04-1117-427/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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. * sysdeps/unix/sysv/linux/arm/pread.c: Remove file. * sysdeps/unix/sysv/linux/arm/pread64.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/pread.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/pread64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/pread.c: Likewise, * sysdeps/unix/sysv/linux/powerpc/powerpc32/pread64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/pread64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (pread): Remove syscall generation. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h [__NR_pread64] (__NR_pread): Remove define. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: [__NR_pread64] (__NR_pread): Likewise. * sysdeps/unix/sysv/linux/pread.c [__NR_pread64] (__NR_pread): Remove define.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * sysdeps/unix/sysv/linux/generic/sysdep.h (__ALIGNMENT_ARG): Move definition.

* Fix limits.h NL_NMAX namespace (bug 19929).Joseph Myers2016-04-083-2/+9
| | | | | | | | | | | | | | | | | | bits/xopen_lim.h (included by limits.h if __USE_XOPEN) defines NL_NMAX, but this constant was removed in the 2008 edition of POSIX so should not be defined in that case. This patch duly disables that define for __USE_XOPEN2K8. It remains enabled for __USE_GNU to avoid affecting sysconf (_SC_NL_NMAX), the implementation of which uses "#ifdef NL_NMAX". Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

| | | | | | | | | | | | | | | | | | | | | | | | bits/termios.h (various versions under sysdeps/unix/sysv/linux) defines XCASE if defined __USE_MISC || defined __USE_XOPEN.
