* Add powf bench testsPaul Clarke2017-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | Add powf() bench test with input which covers these cases: - positive base to positive exponent - exponent 0 - negative base to even exponent - exponent 1 - exponent -1 - squared - squareroot - 1 to negative exponent - -1 to negative exponent - base 0 - -1 to even exponent - small base - small exponent * benchtests/Makefile (bench-math): Add powf. * benchtests/powf-inputs: New file.
* nptl: Invert the mmap/mprotect logic on allocated stacks (BZ#18988)Adhemerval Zanella2017-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. As for the simple benchtests, I saw improvements in thread creation on all architectures I tested the change. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu.

* Rename cppflags-iterator.mk to libof-iterator.mk, remove extra-modules.mk.Zack Weinberg2017-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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. Therefore, this patch gives cppflags-iterator.mk a better name, removes extra-modules.mk, and updates all uses of both. * extra-modules.mk: Delete file. * cppflags-iterator.mk: Rename to ... * libof-iterator.mk: ...this. Adjust comments. * Makerules, extra-lib.mk, benchtests/Makefile, elf/Makefile * elf/rtld-Rules, iconv/Makefile, locale/Makefile, malloc/Makefile * nscd/Makefile, sunrpc/Makefile, sysdeps/s390/Makefile: Use libof-iterator.mk instead of cppflags-iterator.mk or extra-modules.mk. * benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove extra-modules.mk and cppflags-iterator.mk, add libof-iterator.mk.

| | | | | | | | | | of the size and alignment is based on a trace of SPEC2006. Instead of repeating the same copy over and over again like the existing tests, it times several thousand different copies to more accurately estimate the overhead of branch prediction. * benchtests/Makefile (string-benchset): Add memcpy-random. * benchtests/bench-memcpy-random.c: New file.

* Add configure check for python programSiddhesh Poyarekar2016-12-221-2/+8
| | | | | | | | | | | | | | | | | | | Add a configure check that looks for python3 and python in that order since we had agreed in the past to prefer python3 over python in all our code. The patch also adjusts invocations through the various Makefiles to use the set variable. * configure.ac: Check for python3 or python. * configure: Regenerated. * config.make.in (PYTHON): New variable. * benchtests/Makefile: Don't define PYTHON. (bench): Define target only if PYTHON was defined. * Rules: Don't define PYTHON. Define pretty printer targets only if PYTHON was defined. (tests-printers): Add to tests-unsupported if PYTHON is not found. (python-flags, python-invoke): Remove. (tests-printers-out): Use PYTHON instead of python-invoke.
* benchtests: Add fmaxf/fminf benchmarksAdhemerval Zanella2016-12-191-1/+4
| | | | | | | | | | | | | | | | | | | | | | | This patch adds fmaxf and fminf benchtests. It is based on math/s_fmax_template.c implementation which checks for basically four different classes: 1. if x is greater or equal than y. 2. if x is less than y. 3. if x or y is signaling. 4. if y is nan. Cases 1 and 2 are used for default input number (by mixing normal double numbers and infinity), while case 3 and 4 are used each for on for a benchmark class. Checked on x86_64-linux-gnu and powerpc64-linux-gnu. * benchtests/Makefile (bench-math): Add fminf and fmaxf. (CFLAGS-bench-fmaxf.c): New rule. (CFLAGS-bench-fminf.c): Likewise. * benchtests/fmaxf-inputs: New file. * benchtests/fminf-inputs: Likewise.

* Link benchset tests against libsupportSiddhesh Poyarekar2016-12-181-0/+1
| | | | | | | | Benchsets in benchtests use test-skeleton, so they too need to be linked against the new libsupport DSO. * benchtests/Makefile (binaries-benchset): Depend on libsupport DSO.
* Use -fno-builtin for sqrt benchmark.Joseph Myers2016-10-211-0/+1
| | | | | | | | | | | This patch makes the sqrt benchmark use -fno-builtin, as already done for benchmarks of ffs and ffsll, so that it actually benchmarks the glibc function as (presumably) intended even in the presence of the compiler inlining sqrt. Tested for x86_64 and also used for benchmarking my ARM sqrt patch. * benchtests/Makefile (CFLAGS-bench-sqrt.c): New variable.
* benchtests: Support for cross-building benchmarksSiddhesh Poyarekar2016-04-201-4/+19
| | | | | | | | | | | | | | | | 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.
* benchtests: Clean up extra-objsSiddhesh Poyarekar2016-04-201-1/+4
| | | | | The bench-clean target would leave behind json-lib.o. Fix up to clean up all extra-objs registered in benchtests.
* New make target to only build benchmark binariesSiddhesh Poyarekar2016-04-201-1/+4
| | | | | | | | | | | | | | | 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.

* benchtests: ffs and ffsll are string functions, not mathSiddhesh Poyarekar2015-12-091-16/+18
| | | | | | | The ffs and ffsll functions were listed as math functions when they are actually defined in strings.h and string.h respectively. Shuffle around the Makefile variables a bit and make a separate space for ffs and ffsll.

* benchtests: Add malloc microbenchmarkWill Newton2014-11-051-3/+17
| | | | | | | | | | | | | | | | | | | | Add a microbenchmark for measuring malloc and free performance with varying numbers of threads. The benchmark allocates and frees buffers of random sizes in a random order and measures the overall execution time and RSS. Variants of the benchmark are run with 1, 8, 16 and 32 threads. The random block sizes used follow an inverse square distribution which is intended to mimic the behaviour of real applications which tend to allocate many more small blocks than large ones.

* Don't require test wrappers to preserve environment variables, use more ↵Joseph Myers2014-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | consistent environment. One wart in the original support for test wrappers for cross testing, as noted in <https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the requirement for test wrappers to pass a poorly-defined set of environment variables from the build system to the system running the glibc under test. Although some variables are passed explicitly via $(test-wrapper-env), including LD_* variables that simply can't be passed implicitly because of the side effects they'd have on the build system's dynamic linker, others are passed implicitly, including variables such as GCONV_PATH and LOCPATH that could potentially affect the build system's libc (so effectively relying on any such effects not breaking the wrappers). In addition, the code in cross-test-ssh.sh for preserving environment variables is fragile (it depends on how bash formats a list of exported variables, and could well break for multi-line variable definitions where the contents contain things looking like other variable definitions). This patch moves to explicitly passing environment variables via $(test-wrapper-env). Makefile variables that previously used $(test-wrapper) are split up into -before-env and -after-env parts that can be passed separately to the various .sh files used in testing, so those files can then insert environment settings between the two parts. The common default environment settings in make-test-out are made into a separate makefile variable that can also be passed to scripts, rather than many scripts duplicating those settings (for testing an installed glibc, it is desirable to have the GCONV_PATH setting on just one place, so just that one place needs to support it pointing to an installed sysroot instead of the build tree). The default settings are included in the variables such as $(test-program-prefix), so that if tests do not need any non-default settings they can continue to use single variables rather than the split-up variables. Although this patch cleans up LC_ALL=C settings (that being part of the common defaults), various LANG=C and LANGUAGE=C settings remain. Those are generally unnecessary and I propose a subsequent cleanup to remove them. LC_ALL takes precedence over LANG, and while LANGUAGE takes precedence over LC_ALL, it only does so for settings other than LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C locale, and anything that gets LC_ALL=C does not need the other settings. While preparing this patch I noticed some tests with .sh files that appeared to do nothing beyond what the generic makefile support for tests can do (localedata/tst-wctype.sh - the makefiles support -ENV variables and .input files - and localedata/tst-mbswcs.sh - just runs five tests that could be run individually from the makefile). So I propose another subsequent cleanup to move those to using the generic support instead of special .sh files.

In some places glibc's Makefiles use those variables when linking against the relevant libraries, but in other places they hardcode the location of the libraries in the build tree. This patch cleans up various places to use the variables that already exist (in the case of libm, replacing several duplicate definitions of a $(link-libm) variable in subdirectory Makefiles). (It's not necessarily exactly equivalent to what the existing code does - in particular, $(shared-thread-library) includes libpthread_nonshared, but is replacing places that just referred to libpthread.so. But I think that change is desirable on the general principle of linking things as close as possible to the way in which they would be linked with an installed library, unless there is a clear reason not to do so.) To support running tests with an installed copy of glibc without needing the full build tree from when that copy was built, I think it will be useful to use such variables more generally and systematically - every time the rules for building a test refer to some file from the build tree that's also installed by glibc, use a makefile variable so that the installed-testing case can point those variables to installed copies of the files. This patch just deals with straightforward cases where such variables already exist. It's quite possible some uses of $(shared-thread-library) should actually be a new $(thread-library) variable that's set appropriately in the --disable-shared case, if those uses would in fact work without shared libraries. I didn't change the status quo that those cases hardcode use of a shared library whether or not it's actually needed (but other uses such as $(libm) and $(libdl) would now get the static library if the shared library isn't built, when some previously hardcoded use of the shared library - if they actually need shared libraries, the test itself needs an enable-shared conditional anyway).

* benchtests: Link against objects in build directorySiddhesh Poyarekar2014-04-151-23/+9
| | | | | | | | | | Using -lm and -lpthread results in the shared objects in the system being used to link against. This happened to work for libm because there haven't been any changes to the libm ABI recently that could break the existing benchmarks. This doesn't always work for the pthread benchmarks. The correct way to build against libraries in the build directory is to have the binaries explicitly depend on them so that $(+link) can pick them up.

| | | | | | | | | We have a single thread that runs a no-op initialization once and then repeatedly runs checks of the initialization (i.e., an acquire load and conditional jump) in a tight loop. This gives us, on average, the best-case latency of pthread_once (the initialization is the exactly-once slow path, and we're not looking at initialization-related synchronization overheads in this case).
