* string: Improve generic strcmpAdhemerval Zanella2023-02-061-16/+94
| | | | | | | | | | | | | | | | | | | | | It follows the strategy: - Align the first input to word boundary using byte operations. - If second input is also word aligned, read a word per time, check for null (using has_zero), and check final words using byte operation. - If second input is not word aligned, loop by aligning the source, and merging the result of two reads. Similar to aligned case, check for null with has_zero, and check final words using byte operation. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64-linux-gnu, and powerpc-linux-gnu by removing the arch-specific assembly implementation and disabling multi-arch (it covers both LE and BE for 64 and 32 bits).

| | | | | | | | | | | | | | | | | | | | | | | 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

* S390: Optimize strcmp and wcscmp.Stefan Liebler2015-08-261-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides optimized versions of strcmp and wcscmp with the z13 vector instructions. The architecture specific string.h had a typo, which leads to ommiting the inline version in this file if __USE_STRING_INLINES is defined. Tested this inline version by tweaking test-strcmp.c. ChangeLog: * sysdeps/s390/multiarch/strcmp-vx.S: New File. * sysdeps/s390/multiarch/strcmp.c: Likewise. * sysdeps/s390/multiarch/wcscmp-c.c: Likewise. * sysdeps/s390/multiarch/wcscmp-vx.S: Likewise. * sysdeps/s390/multiarch/wcscmp.c: Likewise. * sysdeps/s390/s390-32/multiarch/strcmp.c: Likewise. * sysdeps/s390/s390-64/multiarch/strcmp.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strcmp and wcscmp functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strcmp, wcscmp. * string/strcmp.c (STRCMP): Define and use macro. * benchtests/bench-wcscmp.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcscmp. * sysdeps/s390/bits/string.h: Fix typo: _HAVE_STRING_ARCH_strcmp instead of _HAVE_STRING_ARCH_memchr.

* string: Cosmetic cleanup of string functionsWill Newton2014-04-071-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up string functions that do not have a version in gnulib on the assumption that glibc is the canonical upstream copy of this code. basename has a copy in gnulib but it is largely written to handle Windows paths so merging it is not really viable. The changes mostly consist of switching to ANSI function prototypes and removing unused includes. As many of these functions do not get built in a typical build due to architecture optimized versions being used instead I built these by hand to verify there were no build warnings and the code was identical. 2014-04-07 Will Newton <will.newton@linaro.org> * string/basename.c [HAVE_CONFIG_H]: Remove #ifdef and and contents. [!_LIBC] Remove #ifndef and contents. (basename): Use ANSI prototype. [_LIBC] Remove #idef. * string/memccpy.c (__memccpy): Use ANSI prototype. * string/memfrob.c (memfrob): Likewise. * string/strcoll.c (STRCOLL): Likewise. * string/strlen.c (strlen): Likewise. * string/strtok.c (STRTOK): Likewise. * string/strcat.c: Remove unused #include of memcopy.h. (strcat): Use ANSI prototype. * string/strchr.c: Remove unused #include of memcopy.h. (strchr): Use ANSI prototype. * string/strcmp.c: Remove unused #include of memcopy.h. (strcmp): Use ANSI prototype. * string/strcpy.c: Remove unused #include of memcopy.h. (strcpy): Use ANSI prototype.
