2023-04-17Benchtests: Adjust timingWilco Dijkstra
Adjust iteration counts so benchmarks don't run too slowly or quickly. Ensure benchmarks take less than 10 seconds on older, slower cores and more than 0.5 seconds on fast cores. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

2022-11-08benchtests: Make str{n}{cat|cpy} benchmarks output jsonNoah Goldstein
Json output is easier to parse and most other benchmarks already do the same.

I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ !

2019-06-28Bump up the runtime for "short" benchmarksAnton Youdkevitch
Some benchmarks with a very short runtime show significantly different results across runs on Aarch64 - up to tens of percents. Increasing the runtime to 100ms+ makes the deviation under 5%.

2013-09-04benchtests: Switch string benchmarks to use bench-timing.h.Will Newton
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.
