* Adjust benchtests to new support library.Adhemerval Zanella2016-12-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch basically replaces the test-skeleton.c inclusion by support/test-driver.c and also minor adjustments in bench-string.h. Checked on x86_64-linux-gnu and powerpc64le-linux-gnu. * benchtests/bench-string.h (TEST_FUNCTION): Use name without parenthesis. (CMDLINE_PROCESS): Define using function instead of macro. * benchtests/bench-memccpy.c: Include <support/test-driver.c> instead of test-skeleton. * benchtests/bench-memchr.c: Likewise. * benchtests/bench-memcmp.c: Likewise. * benchtests/bench-memcpy-large.c: Likewise. * benchtests/bench-memcpy.c: Likewise. * benchtests/bench-memmem.c: Likewise. * benchtests/bench-memmove-large.c: Likewise. * benchtests/bench-memmove.c: Likewise. * benchtests/bench-memset-large.c: Likewise. * benchtests/bench-memset.c: Likewise. * benchtests/bench-rawmemchr.c: Likewise. * benchtests/bench-strcasecmp.c: Likewise. * benchtests/bench-strcasestr.c: Likewise. * benchtests/bench-strcat.c: Likewise. * benchtests/bench-strchr.c: Likewise. * benchtests/bench-strcmp.c: Likewise. * benchtests/bench-strcpy.c: Likewise. * benchtests/bench-strcpy_chk.c: Likewise. * benchtests/bench-strlen.c: Likewise. * benchtests/bench-strncasecmp.c: Likewise. * benchtests/bench-strncmp.c: Likewise. * benchtests/bench-strncpy.c: Likewise. * benchtests/bench-strnlen.c: Likewise. * benchtests/bench-strpbrk.c: Likewise. * benchtests/bench-strrchr.c: Likewise. * benchtests/bench-strsep.c: Likewise. * benchtests/bench-strspn.c: Likewise. * benchtests/bench-strstr.c: Likewise. * benchtests/bench-strtok.c: Likewise.
* Clear destination buffer updated by the previous runH.J. Lu2016-05-181-0/+4
| | | | | | | | | | | | | 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.
* Test 64-byte alignment in memcpy benchtestH.J. Lu2016-04-011-0/+8
| | | | | | | Add 64-byte alignment tests in memcpy benchtest for 64-byte vector registers. * benchtests/bench-memcpy.c (test_main): Test 64-byte alignment.

* benchtests: Switch string benchmarks to use bench-timing.h.Will Newton2013-09-041-19/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch the string benchmarks to using bench-timing.h instead of hp-timing.h directly. This allows the string benchmarks to be run usefully on architectures such as ARM that do not have support for hp-timing.h. In order to do this the tests have been changed from timing each individual call and picking the lowest execution time recorded to timing a number of calls and taking the mean execution time. ChangeLog: 2013-09-04 Will Newton <will.newton@linaro.org> * benchtests/bench-timing.h (TIMING_PRINT_MEAN): New macro. * benchtests/bench-string.h: Include bench-timing.h instead of including hp-timing.h directly. (INNER_LOOP_ITERS): New define. (HP_TIMING_BEST): Delete macro. (test_init): Remove call to HP_TIMING_DIFF_INIT. * benchtests/bench-memccpy.c: Use bench-timing.h macros instead of hp-timing.h macros. * benchtests/bench-memchr.c: Likewise. * benchtests/bench-memcmp.c: Likewise. * benchtests/bench-memcpy.c: Likewise. * benchtests/bench-memmem.c: Likewise. * benchtests/bench-memmove.c: Likewise. * benchtests/bench-memset.c: Likewise. * benchtests/bench-rawmemchr.c: Likewise. * benchtests/bench-strcasecmp.c: Likewise. * benchtests/bench-strcasestr.c: Likewise. * benchtests/bench-strcat.c: Likewise. * benchtests/bench-strchr.c: Likewise. * benchtests/bench-strcmp.c: Likewise. * benchtests/bench-strcpy.c: Likewise. * benchtests/bench-strcpy_chk.c: Likewise. * benchtests/bench-strlen.c: Likewise. * benchtests/bench-strncasecmp.c: Likewise. * benchtests/bench-strncat.c: Likewise. * benchtests/bench-strncmp.c: Likewise. * benchtests/bench-strncpy.c: Likewise. * benchtests/bench-strnlen.c: Likewise. * benchtests/bench-strpbrk.c: Likewise. * benchtests/bench-strrchr.c: Likewise. * benchtests/bench-strspn.c: Likewise. * benchtests/bench-strstr.c: Likewise.
* Begin porting string performance tests to benchtestsSiddhesh Poyarekar2013-06-111-0/+163
This is the initial support for string function performance tests, along with copying tests for memcpy and memcpy-ifunc as proof of concept. The string function benchmarks perform operations at different alignments and for different sizes and compare performance between plain operations and the optimized string operations. Due to this their output is incompatible with the function benchmarks where we're interested in fastest time, throughput, etc. In future, the correctness checks in the benchmark tests can be removed. Same goes for the performance measurements in the string/test-*.
