* Clear destination buffer updated by the previous runH.J. Lu2016-05-181-0/+1
| | | | | | | | | | | | | 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 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.

* benchtests: Switch string benchmarks to use bench-timing.h.Will Newton2013-09-041-20/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Fix loop construction to functions callsAdhemerval Zanella2013-06-201-0/+1
| | | | | | Check wheter the compiler has the option -fno-tree-loop-distribute-patterns to inhibit loop transformation to library calls and uses it on memset and memmove default implementation to avoid recursive calls.
* Copy over string performance tests into benchtestsSiddhesh Poyarekar2013-06-111-0/+187
Copy over already existing string performance tests into benchtests. Bits not related to performance measurements have been omitted.
