* Remove TEST_IFUNC, tests-ifunc and *-ifunc.c tests.Joseph Myers2014-11-261-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TEST_IFUNC is only tested in two headers, bench-string.h and test-string.h, after it gets defined by those headers, and it never gets undefined. Thus no defines of TEST_IFUNC are needed, and the *-ifunc.c tests that just define TEST_IFUNC and include other tests are also redundant, as is the code to remove $(tests-ifunc) and $(xtests-ifunc) conditionally from tests and xtests. This patch removes the useless defines and tests of TEST_IFUNC and the associated useless tests and makefile code. It thereby fixes a series of warnings "../string/test-string.h:21:0: warning: "TEST_IFUNC" redefined" where test-string.h defines TEST_IFUNC to empty, other files define it to 1 and this produces warnings. Tested for x86_64. * debug/test-stpcpy_chk-ifunc.c: Remove file. * debug/test-strcpy_chk-ifunc.c: Likewise. * wcsmbs/test-wcschr-ifunc.c: Likewise. * wcsmbs/test-wcscmp-ifunc.c: Likewise. * wcsmbs/test-wcscpy-ifunc.c: Likewise. * wcsmbs/test-wcslen-ifunc.c: Likewise. * wcsmbs/test-wcsrchr-ifunc.c: Likewise. * wcsmbs/test-wmemcmp-ifunc.c: Likewise. * Rules [$(multi-arch) = no] (tests): Do not filter out $(tests-ifunc).

* benchtests: Add malloc microbenchmarkWill Newton2014-11-052-3/+319
| | | | | | | | | | | | | | | | | | | | 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. ChangeLog: 2014-11-05 Will Newton <will.newton@linaro.org> * benchtests/Makefile: (bench-malloc): Add malloc thread scalability benchmark. * benchtests/bench-malloc-threads.c: New file.
* PowerPC: memset optimization for POWER8/PPC64Adhemerval Zanella2014-09-101-0/+5
| | | | | | | | | | | | | | | | | | | This patch adds an optimized memset implementation for POWER8. For sizes from 0 to 255 bytes, a word/doubleword algorithm similar to POWER7 optimized one is used. For size higher than 255 two strategies are used: 1. If the constant is different than 0, the memory is written with altivec vector instruction; 2. If constant is 0, dbcz instructions are used. The loop is unrolled to clear 512 byte at time. Using vector instructions increases throughput considerable, with a double performance for sizes larger than 1024. The dcbz loops unrolls also shows performance improvement, by doubling throughput for sizes larger than 8192 bytes.
* Remove HP_TIMING_DIFF_INIT and dl_hp_timing_overheadRichard Henderson2014-07-032-8/+1

* 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.

* benchtests: Add new directive for benchmark initialization hookSiddhesh Poyarekar2014-05-263-1/+10
| | | | | | | Add a new 'init' directive that specifies the name of the function to call to do function-specific initialization. This is useful for benchmarks that need to do a one-time initialization before the functions are executed.
* Use existing makefile variables for dependencies on glibc libraries.Joseph Myers2014-05-161-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc's Makeconfig defines some variables such as $(libm) and $(libdl) for linking with libraries built by glibc, and nptl/Makeconfig (included by the toplevel Makeconfig) defines others such as $(shared-thread-library). 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.

* benchtests: Add pthread_once common-case test.Torvald Riegel2014-04-104-1/+38
| | | | | | | | | 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).

* Detailed benchmark outputs for functionsSiddhesh Poyarekar2014-03-293-2/+34
| | | | | | | | This patch adds an option to get detailed benchmark output for functions. Invoking the benchmark with 'make DETAILED=1 bench' causes each benchmark program to store a mean execution time for each input it works on. This is useful to give a more comprehensive picture of performance of functions compared to just the single mean figure.
* Make bench.out in json formatSiddhesh Poyarekar2014-03-295-18/+66
| | | | | | | | | | | | | | This patch changes the output format of the main benchmark output file (bench.out) to an extensible format. I chose JSON over XML because in addition to being extensible, it is also not too verbose. Additionally it has good support in python. The significant change I have made in terms of functionality is to put timing information as an attribute in JSON instead of a string and to do that, there is a separate program that prints out a JSON snippet mentioning the type of timing (hp_timing or clock_gettime). The mean timing has now changed from iterations per unit to actual timing per iteration.

* Consistently include Makeconfig after defining subdir.Joseph Myers2014-02-261-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed.

* Benchmark inputs for cos and sinSiddhesh Poyarekar2013-12-312-12/+5300
| | | | | | Add a comprehensive number of inputs for all branches in sin and cos computation, excluding the fast paths. This also adds a number of inputs for the multiple precision slow paths.
* benchmark inputs for atanSiddhesh Poyarekar2013-12-311-5/+802
| | | | | | | Add a more comprehensive set of inputs for the atan function. I have also fixed the name on the multiple precision fallback inputs (I couldn't find any new inputs there) to reflect the fact that the fallback is only 144bits and not 768bits as I had earlier mentioned.

* benchmark inputs for asinh and acoshSiddhesh Poyarekar2013-12-312-10/+600
| | | | | | Like sinh and cosh, this patch has benchmark inputs for asinh and acosh, generated using a random number generator and spread over significant branches, ignoring the fast return paths.
* benchmark inputs for sinh and coshSiddhesh Poyarekar2013-12-312-10/+700
| | | | | | | Add a full set of inputs for sinh and cosh functions generated using a random number generator and spreading it over all branches in the function, ignoring the fast paths (i.e. immediate return for special values).
* benchmark inputs for asin and acosSiddhesh Poyarekar2013-12-312-14/+5240
| | | | | Add a comprehensive set of inputs for asin and acos functions, including the multiple precision fallback path.

* Accept output arguments to benchmark functionsSiddhesh Poyarekar2013-12-053-87/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the ability to accept output arguments to functions being benchmarked, by nesting the argument type in <> in the args directive. It includes the sincos implementation as an example, where the function would have the following args directive: ## args: double:<double *>:<double *> This simply adds a definition for a static variable whose pointer gets passed into the function, so it's not yet possible to pass something more complicated like a pre-allocated string or array. That would be a good feature to add if a function needs it. The values in the input file will map only to the input arguments. So if I had a directive like this for a function foo: ## args: int:<int *>:int:<int *> and I have a value list like this: 1, 2 3, 4 5, 6 then the function calls generated would be: foo (1, &out1, 2, &out2); foo (3, &out1, 4, &out2); foo (5, &out1, 6, &out2);

* Benchmark inputs for powSiddhesh Poyarekar2013-10-281-0/+503
| | | | | These inputs cover all normal processing paths for pow including all its slow paths.
* New inputs for expSiddhesh Poyarekar2013-10-281-0/+581
| | | | | | A more comprehensive set of inputs for exp, including all slow paths. The inputs have been shuffled so that they don't give a false-positive due to a hot cache.
* benchtests: Add include-sources directive.Torvald Riegel2013-10-101-2/+5
| | | | | | This adds the "include-sources" directive to scripts/bench.pl. This allows for including source code (vs including headers, which might get a different search path) after the inclusion of any headers.
* Add more directives to benchmark input filesSiddhesh Poyarekar2013-10-0718-67/+67
| | | | | | | | | | | | | | | | | | | | | | This patch adds some more directives to the benchmark inputs file, moving functionality from the Makefile and making the code generation script a bit cleaner. The function argument and return types that were earlier added as variables in the makefile and passed to the script via command line arguments are now the 'args' and 'ret' directive respectively. 'args' should be a colon separated list of argument types (skipped if the function doesn't accept any arguments) and 'ret' should be the return type. Additionally, an 'includes' directive may have a comma separated list of headers to include in the source. For example, the pow input file now looks like this: 42.0, 42.0 1.0000000000000020, 1.5 I did this to unclutter the benchtests Makefile a bit and eventually eliminate dependency of the tests on the Makefile and have tests depend on their respective include files only.

* benchtests: Rename argument to TIMING_INIT macro.Will Newton2013-09-112-10/+10
| | | | | | | | | | | | | | | | The TIMING_INIT macro currently sets the number of loop iterations to 1000, which limits usefulness. Make the argument a clock resolution value and multiply by 1000 in bench-skeleton.c instead to allow easier reuse. ChangeLog: 2013-09-11 Will Newton <will.newton@linaro.org> * benchtests/bench-timing.h (TIMING_INIT): Rename ITERS parameter to RES. Remove hardcoded 1000 value. * benchtests/bench-skeleton.c (main): Pass RES parameter to TIMING_INIT and multiply result by 1000.
* benchtests: Add memrchr benchmarkAdhemerval Zanella2013-09-064-4/+66
