*	S390: Refactor strlen ifunc handling.	Stefan Liebler	2018-12-18	1	-28/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The ifunc handling for strlen is adjusted in order to omit ifunc variants if those will never be used as the minimum architecture level already supports newer CPUs by default. Glibc internal calls will then also use the "newer" ifunc variant. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove strlen variants. * sysdeps/s390/Makefile (sysdep_routines): Add strlen variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for strlen. * sysdeps/s390/multiarch/strlen-c.c: Move to ... * sysdeps/s390/strlen-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/strlen-vx.S: Move to ... * sysdeps/s390/strlen-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/strlen.c: Move to ... * sysdeps/s390/strlen.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-strlen.h: New file.

*	S390: Optimize strlen and wcslen.	Stefan Liebler	2015-08-26	1	-0/+28
	This patch provides optimized versions of strlen and wcslen with the z13 vector instructions. The helper macro IFUNC_VX_IMPL is introduced and is used to register all __<func>_c() and __<func>_vx() functions within __libc_ifunc_impl_list() to the ifunc test framework. ChangeLog: * sysdeps/s390/multiarch/Makefile: New File. * sysdeps/s390/multiarch/strlen-c.c: Likewise. * sysdeps/s390/multiarch/strlen-vx.S: Likewise. * sysdeps/s390/multiarch/strlen.c: Likewise. * sysdeps/s390/multiarch/wcslen-c.c: Likewise. * sysdeps/s390/multiarch/wcslen-vx.S: Likewise. * sysdeps/s390/multiarch/wcslen.c: Likewise. * string/strlen.c (STRLEN): Define and use macro. * sysdeps/s390/multiarch/ifunc-impl-list.c (IFUNC_VX_IMPL): New macro function. (__libc_ifunc_impl_list): Add ifunc test for strlen, wcslen. * benchtests/Makefile (wcsmbs-bench): New variable. (string-bench-all): Added wcsmbs-bench. * benchtests/bench-wcslen.c: New File.
