* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | 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 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* Improve string benchtest timingWilco Dijkstra2019-05-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Improve string benchtest timing. Many tests run for 0.01s which is way too short to give accurate results. Other tests take over 40 seconds which is way too long. Significantly increase the iterations of the short running tests. Reduce number of alignment variations in the long running memcpy walk tests so they take less than 5 seconds. As a result most tests take at least 0.1s and all finish within 5 seconds. * benchtests/bench-memcpy-random.c (do_one_test): Use medium iterations. * benchtests/bench-memcpy-walk.c (test_main): Reduce alignment tests. * benchtests/bench-memmem.c (do_one_test): Use small iterations. * benchtests/bench-memmove-walk.c (test_main): Reduce alignment tests. * benchtests/bench-memset-walk.c (test_main): Reduce alignment tests. * benchtests/bench-strcasestr.c (do_one_test): Use small iterations. * benchtests/bench-string.h (INNER_LOOP_ITERS): Increase iterations.

* This patch cleans up the strsep implementation and improves performance.Wilco Dijkstra2016-12-211-21/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently strsep calls strpbrk is is now a veneer to strcspn. Calling strcspn directly is faster. Since it handles a delimiter string of size 1 as a special case, this is not needed in strsep itself. Although this means there is a slightly higher overhead if the delimiter size is 1, all other cases are slightly faster. The overall performance gain is 5-10% on AArch64. The string/bits/string2.h header contains optimizations for constant delimiters of size 1-3. Benchmarking these showed similar performance for size 1 (since in all cases strchr/strchrnul is used), while size 2 and 3 can give up to 2x speedup for small input strings. However if these cases are common it seems much better to add this optimization to strcspn. So move these header optimizations to string-inlines.c. Improve the strsep benchmark so that it actually benchmarks something. The current version contains a delimiter character at every position in the input string, so there is very little work to do, and the extremely inefficent simple_strsep implementation appears fastest in every case. The new version has either no match in the input for the fail case and a match halfway in the input for the success case. The input is then restored so that each iteration does exactly the same amount of work. Reduce the number of testcases since simple_strsep takes a lot of time now. * benchtests/bench-strsep.c (oldstrsep): Add old implementation. (do_one_test) Restore original string so iteration works. * string/string-inlines.c (do_test): Create better input strings. (test_main) Reduce number of testruns. * string/string-inlines.c (__old_strsep_1c): New function. (__old_strsep_2c): Likewise. (__old_strsep_3c): Likewise. * string/strsep.c (__strsep): Remove case of small delim string. Call strcspn directly rather than strpbrk. * string/bits/string2.h (__strsep): Remove define. (__strsep_1c): Remove. (__strsep_2c): Remove. (__strsep_3c): Remove. (strsep): Remove. * sysdeps/unix/sysv/linux/internal_statvfs.c (__statvfs_getflags): Rename to __strsep.
