From 2e02d0b7a9bf3421638d2d0f2526275a1df5c0da Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:17 +0100 Subject: S390: Refactor wcslen ifunc handling. The ifunc handling for wcslen is adjusted in order to omit ifunc if the minimum architecture level already supports newer CPUs by default. Unfortunately the c ifunc variant can't be omitted at all as it is used by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wcslen variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcslen variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcslen. * sysdeps/s390/multiarch/wcslen-c.c: Move to ... * sysdeps/s390/wcslen-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcslen-vx.S: Move to ... * sysdeps/s390/wcslen-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcslen.c: Move to ... * sysdeps/s390/wcslen.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcslen.h: New file. --- sysdeps/s390/Makefile | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'sysdeps/s390/Makefile') diff --git a/sysdeps/s390/Makefile b/sysdeps/s390/Makefile index 0e86242c5d..10c0e1bea0 100644 --- a/sysdeps/s390/Makefile +++ b/sysdeps/s390/Makefile @@ -81,3 +81,7 @@ sysdep_routines += bzero memset memset-z900 \ memccpy memccpy-vx memccpy-c \ memrchr memrchr-vx memrchr-c endif + +ifeq ($(subdir),wcsmbs) +sysdep_routines += wcslen wcslen-vx wcslen-c +endif -- cgit 1.4.1
