* 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.
* Clear destination buffer updated by the previous runH.J. Lu2016-05-182-0/+5
| | | | | | | | | | | | | Clear the destination buffer updated by the previous run in bench-memcpy.c and test-memcpy.c to catch the error when the following implementations do not copy anything. [BZ #19907] * benchtests/bench-memcpy.c (do_one_test): Clear the destination buffer updated by the previous run. * string/test-memcpy.c (do_one_test): Likewise. * benchtests/bench-memmove.c (do_one_test): Add a comment. * string/test-memmove.c (do_one_test): Likewise.
* benchtests: Support for cross-building benchmarksSiddhesh Poyarekar2016-04-202-5/+22
| | | | | | | | | | | | | | | | 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.
* localedata: iw_IL: delete old/deprecated locale [BZ #16137]Mike Frysinger2016-04-084-4/+3
| | | | | | | | From the bug: Obsolete locale. The ISO-639 code for Hebrew was changed from 'iw' to 'he' in 1989, according to Bruno Haible on libc-alpha 2003-09-01. Reported-by: Chris Leonard <cjlhomeaddress@gmail.com>
* Add memcpy/memmove/memset benchmarks with large dataH.J. Lu2016-04-065-2/+384

* Test 64-byte alignment in memset benchtestH.J. Lu2016-04-011-1/+6
| | | | | | | | | Add 64-byte alignment tests in memset benchtest for 64-byte vector registers. * benchtests/bench-memset.c (do_test): Support 64-byte alignment. (test_main): Test 64-byte alignment.
* Test 64-byte alignment in memmove benchtestH.J. Lu2016-04-011-0/+8
| | | | | | | | Add 64-byte alignment tests in memmove benchtest for 64-byte vector registers. * benchtests/bench-memmove.c (test_main): Test 64-byte alignment.

* Support --enable-hardcoded-path-in-tests in benchtestsH.J. Lu2016-03-081-2/+2
| | | | | | | | | | benchtests should use $(test-via-rtld-prefix) and $(+link-tests) like other glibc tests. [BZ #19783] * benchtests/Makefile (run-bench): Replace $(rtld-prefix) with $(test-via-rtld-prefix). ($(binaries-bench)): Replace $(+link) with $(+link-tests).

* 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 inputs from sin and cos to sincosSiddhesh Poyarekar2015-12-091-0/+5102
| | | | | | | The sincos benchmark has only about a dozen inputs that don't measure the impact of changes to various passes. Since much of the code properties are inherited from sin and cos, copy those inputs in to get more comprehensive coverage.
* benchtests: Mark output variables as usedSiddhesh Poyarekar2015-11-171-1/+1
| | | | | | | | Prevent function calls that don't return anything from being optimized out by the compiler by marking its input variables as used. This prevents the sincos function call from being optimized out in the benchmark.
* Add a new benchmark for isinf/isnan/isnormal/isfinite/fpclassify. The test ↵Wilco Dijkstra2015-09-185-16/+355

* benchtest: script to compare two benchmarksSiddhesh Poyarekar2015-06-012-0/+280
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This script is a sample implementation that uses import_bench to construct two benchmark objects and compare them. If detailed timing information is available (when one does `make DETAILED=1 bench`), it writes out graphs for all functions it benchmarks and prints significant differences in timings of the two benchmark runs. If detailed timing information is not available, it points out significant differences in aggregate times. Call this script as follows: compare_bench.py schema_file.json bench1.out bench2.out Alternatively, if one wants to set a different threshold for warnings (default is a 10% difference): compare_bench.py schema_file.json bench1.out bench2.out 25 The threshold in the example above is 25%. schema_file.json is the JSON schema (which is $srcdir/benchtests/scripts/benchout.schema.json for the benchmark output file) and bench1.out and bench2.out are the two benchmark output files to compare. The key functionality here is the compress_timings function which groups together points that are close together into a single point that is the mean of all its representative points. Any point in such a group is at most 1.5x the smallest point in that group. The detailed derivation is a comment in the function. * benchtests/scripts/compare_bench.py: New file. * benchtests/scripts/import_bench.py (mean): New function. (split_list): Likewise.

* New module to import and process benchmark outputSiddhesh Poyarekar2015-06-012-25/+71
| | | | | | | | | | | | | | | This is the beginning of a module to import and process benchmark outputs. The module currently supports importing of a bench.out and validating it against a schema file. In future this could grow a set of routines that benchmark consumers may find useful to build their own analysis tools. I have altered validate_bench to use this module too. * benchtests/scripts/import_bench.py: New file. * benchtests/scripts/validate_benchout.py: Import import_bench instead of jsonschema. (validate_bench): Remove function. (main): Use import_bench.

* powerpc: POWER7 strcpy optimization for unaligned stringsRajalakshmi Srinivasaraghavan2014-12-311-0/+16
| | | | | | | | | | | | | | | | This patch optimizes strcpy for ppc64/power7 for unaligned source or destination address. The source or destination address is aligned to doubleword and data is shifted based on the alignment and added with the previous loaded data to be written as a doubleword. For each load, cmpb instruction is used for faster null check. The word aligned optimization is also removed, since the new unaligned code path shows better results handling word-aligned strings. More combination of unaligned inputs is also added in benchtest to measure the improvement.The new optimization shows 2 to 80% of performance improvement for longer string though it does not show big difference on string size less than 16 due to additional checks.
* 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.
