2019-04-25benchtests: Enable BIND_NOW if configured with --enable-bind-nowFlorian Weimer
Benchmarks should reflect distribution build policies, so it makes sense to honor the BIND_NOW configuration for them. This commit keeps using $(+link-tests), so that the benchmarks are linked according to the --enable-hardcoded-path-in-tests configure option. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2019-04-24Reduce benchtests timeWilco Dijkstra
Reduce the total time taken by benchtests. The malloc thread test takes 4 minutes to run which is significantly more than most other tests. Reduce this to a more reasonable 40 seconds. The math tests take 10 seconds each, eventhough all they do is loop on the same input. Anything more than 1 second runtime is way overkill, so set the limit to 1 second. * benchtests/Makefile (BENCH_DURATION): Set to 1 second. * benchtests/bench-malloc-thread.c (BENCH_DURATION): Set to 10 seconds.
2019-03-22Add generic hp-timing supportWilco Dijkstra
Add missing generic hp_timing support. It uses clock_gettime (CLOCK_MONOTONIC) which has unspecified starting time, nano-second accuracy, and should faster on architectures that implementes the symbol as vDSO. Checked on aarch64-linux-gnu, x86_64-linux-gnu, and i686-linux-gnu. I also checked the builds for all afected ABIs. * benchtests/Makefile (USE_CLOCK_GETTIME) Remove. * benchtests/README: Update description. * benchtests/bench-timing.h: Default to hp-timing. * sysdeps/generic/hp-timing.h (HP_TIMING_DIFF, HP_TIMING_ACCUM_NT, HP_TIMING_PRINT): Remove. (HP_TIMING_NOW): Add generic implementation. (hp_timing_t): Change to uint64_t.
2019-02-14Add malloc micro benchmarkWilco Dijkstra
Add a malloc micro benchmark to enable accurate testing of the various paths in malloc and free. The benchmark does a varying number of allocations of a given block size, then frees them again. It tests 3 different scenarios: single-threaded using main arena, multi-threaded using thread-arena, main arena with SINGLE_THREAD_P false. * benchtests/Makefile: Add malloc-simple benchmark. * benchtests/bench-malloc-simple.c: New benchmark.
2019-02-12String benchtest cleanupWilco Dijkstra
Continue cleanup of the string benchtests. Remove simplistic byte-oriented versions with faster generic implementations. Remove bcopy/bzero benchmarks (bcopy/bzero are obsolete and never emitted by compilers). Remove builtin versions of memcpy, memset and strlen. Remove all remaining "stupid" implementations given they are always slower than the "simple" variants and thus don't add anything useful. * benchtests/bench-strcasecmp.c (stupid_strcasecmp): Remove. * benchtests/bench-strcasestr.c (stupid_strcasestr): Remove. * benchtests/bench-strchr.c (stupid_strchr): Remove. * benchtests/bench-strcmp.c (stupid_strcmp): Remove. * benchtests/bench-strcspn.c (stupid_strcspn): Remove. * benchtests/bench-strlen.c (builtin_strlen): Remove. * benchtests/bench-strncasecmp.c (stupid_strncasecmp): Remove. * benchtests/bench-strncmp.c (stupid_strncmp): Remove. * benchtests/bench-strpbrk.c (stupid_strpbrk): Remove. * benchtests/bench-strspn.c (stupid_strspn): Remove. * benchtests/Makefile: Remove bench-bcopy.c and bench-bzero.c. * benchtests/bench-bcopy.c: Delete file. * benchtests/bench-bzero.c: Likewise. * benchtests/bench-memccpy.c (stupid_memccpy): Remove.

2018-10-29Patch to require Python 3.4 or later to build glibc.Joseph Myers
This patch makes Python 3.4 or later a required tool for building glibc, so allowing changes of awk, perl etc. code used in the build and test to Python code without any such changes needing makefile conditionals or to handle older Python versions. This patch makes the configure test for Python check the version and give an error if Python is missing or too old, and removes makefile conditionals that are no longer needed. It does not itself convert any code from another language to Python, and does not remove any compatibility with older Python versions from existing scripts. Tested for x86_64. * configure.ac (PYTHON_PROG): Use AC_CHECK_PROG_VER. Set critic_missing for versions before 3.4. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Document requirement for Python to build glibc. * INSTALL: Regenerated. * Rules [PYTHON]: Make code unconditional. * benchtests/Makefile [PYTHON]: Likewise. * conform/Makefile [PYTHON]: Likewise. * manual/Makefile [PYTHON]: Likewise. * math/Makefile [PYTHON]: Likewise.
2018-10-24x86: Support RDTSCP for benchtestsH.J. Lu
RDTSCP waits until all previous instructions have executed and all previous loads are globally visible before reading the counter. RDTSC doesn't wait until all previous instructions have been executed before reading the counter. All x86 processors since 2010 support RDTSCP instruction. This patch adds RDTSCP support to benchtests. * benchtests/Makefile (CPPFLAGS-nonlib): Add -DUSE_RDTSCP if USE_RDTSCP is defined. * sysdeps/x86/hp-timing.h (HP_TIMING_NOW): Use RDTSCP if USE_RDTSCP is defined.
2018-03-15Use correct includes in benchtestsWilco Dijkstra
Currently the benchtests are run with internal GLIBC headers, which is incorrect. Defining _ISOMAC in the makefile ensures the internal headers are bypassed. Fix all tests which were relying on internal defines or includes. * benchtests/Makefile: Define _ISOMAC. * benchtests/bench-strcoll.c: Add missing sys/stat.h include. * benchtests/bench-string.h: Define inhibit_loop_to_libcall macro. * benchtests/bench-strstr.c: Define empty libc_hidden_builtin_def. * benchtests/bench-strtok.c (oldstrtok): Use rawmemchr. * benchtests/bench-timing.h: Define attribute_hidden.

2017-10-05benchtests: Memory walking benchmark for memmoveSiddhesh Poyarekar
This benchmark is an attempt to eliminate cache effects from string benchmarks. The benchmark walks both ways through a large memory area and copies different sizes of memory and alignments one at a time instead of looping around in the same memory area. This is a good metric to have alongside the simple memmove benchmark (which is only really useful for smaller sizes) especially for larger sizes where the likelihood of the call being done only once is pretty high. This benchmark is different from memcpy in that it also tests overlapping copies. * benchtests/bench-memmove-walk.c: New file. * benchtests/Makefile (string-benchset): Add it.

2017-06-14nptl: Invert the mmap/mprotect logic on allocated stacks (BZ#18988)Adhemerval Zanella
Current allocate_stack logic for create stacks is to first mmap all the required memory with the desirable memory and then mprotect the guard area with PROT_NONE if required. Although it works as expected, it pessimizes the allocation because it requires the kernel to actually increase commit charge (it counts against the available physical/swap memory available for the system). The only issue is to actually check this change since side-effects are really Linux specific and to actually account them it would require a kernel specific tests to parse the system wide information. On the kernel I checked /proc/self/statm does not show any meaningful difference for vmm and/or rss before and after thread creation. I could only see really meaningful information checking on system wide /proc/meminfo between thread creation: MemFree, MemAvailable, and Committed_AS shows large difference without the patch. I think trying to use these kind of information on a testcase is fragile. The BZ#18988 reports shows that the commit pages are easily seen with mlockall (MCL_FUTURE) (with lock all pages that become mapped in the process) however a more straighfoward testcase shows that pthread_create could be faster using this patch: -- static const int inner_count = 256; static const int outer_count = 128; static void *thread1(void *arg) { return NULL; } static void *sleeper(void *arg) { pthread_t ts[inner_count]; for (int i = 0; i < inner_count; i++) pthread_create (&ts[i], &a, thread1, NULL); for (int i = 0; i < inner_count; i++) pthread_join (ts[i], NULL); return NULL; } int main(void) { pthread_attr_init(&a); pthread_attr_setguardsize(&a, 1<<20); pthread_attr_setstacksize(&a, 1134592); pthread_t ts[outer_count]; for (int i = 0; i < outer_count; i++) pthread_create(&ts[i], &a, sleeper, NULL); for (int i = 0; i < outer_count; i++) pthread_join(ts[i], NULL); assert(r == 0); } return 0; } -- On x86_64 (4.4.0-45-generic, gcc 5.4.0) running the small benchtests I see: $ time ./test real 0m3.647s user 0m0.080s sys 0m11.836s While with the patch I see: $ time ./test real 0m0.696s user 0m0.040s sys 0m1.152s So I added a pthread_create benchtest (thread_create) which check the thread creation latency.

2017-05-09Rename cppflags-iterator.mk to libof-iterator.mk, remove extra-modules.mk.Zack Weinberg
cppflags-iterator.mk no longer has anything to do with CPPFLAGS; all it does is set libof-$(foo) for a list of files. extra-modules.mk does the same thing, but with a different input variable, and doesn't let the caller control the module.
