* New make target to only build benchmark binariesSiddhesh Poyarekar2016-04-201-0/+7
| | | | | | | | | | | | | | | 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.

* Fix pread consolidation on ports that require argument alignmentAdhemerval Zanella2016-04-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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). This was shown on arm with failing cases: FAIL: debug/tst-chk1 FAIL: debug/tst-chk2 FAIL: debug/tst-chk3 FAIL: debug/tst-chk4 FAIL: debug/tst-chk5 FAIL: debug/tst-chk6 FAIL: debug/tst-lfschk1 FAIL: debug/tst-lfschk2 FAIL: debug/tst-lfschk3 FAIL: debug/tst-lfschk4 FAIL: debug/tst-lfschk5 FAIL: debug/tst-lfschk6 FAIL: posix/tst-preadwrite FAIL: posix/tst-preadwrite64 The patches fixes it.

* Fix strfmon_l: Use specified locale for number formatting [BZ #19633]Stefan Liebler2016-04-141-0/+7
| | | | | | | | | | | | | | | | | | 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 Weimer2016-04-141-0/+17
| | | | | | | 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: Remove unused definitions of thread_atfork, thread_atfork_staticFlorian Weimer2016-04-141-0/+7

* malloc: Run fork handler as late as possible [BZ #19431]Florian Weimer2016-04-141-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Weimer2016-04-141-0/+31
| | | | | | | 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.
* Register extra test objectsAndreas Schwab2016-04-131-0/+14
| | | | | This makes sure that the extra test objects are compiled with the correct MODULE_NAME and dependencies are tracked.
* X86-64: Use non-temporal store in memcpy on large dataH.J. Lu2016-04-121-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(PREFETCH_SIZE): Likewise. (PREFETCHED_LOAD_SIZE): Likewise. (PREFETCH_ONE_SET): 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 Fortune2016-04-121-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Zanella2016-04-111-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates all the pwrite/pwrite64 implementation for Linux in only one (sysdeps/unix/sysv/linux/pwrite{64}.c).

* Consolidate off_t/off64_t syscall argument passingAdhemerval Zanella2016-04-111-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Myers2016-04-081-0/+6
| | | | | | | | | | | | | | | | | | 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). [BZ #19929] * include/bits/xopen_lim.h (NL_NMAX): Do not define if [__USE_XOPEN2K8 && !__USE_GNU]. * conform/Makefile (test-xfail-XOPEN2K8/limits.h/conform): Remove variable.
