From d2a7436c1c6144bbba2eb2a7b25db9b90515f0e6 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:24 +0100 Subject: S390: Refactor wmemset ifunc handling. The ifunc handling for wmemset 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. Glibc internal calls will use the "newer" ifunc variant. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wmemset variants. * sysdeps/s390/Makefile (sysdep_routines): Add wmemset variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wmemset. * sysdeps/s390/multiarch/wmemset-c.c: Move to ... * sysdeps/s390/wmemset-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wmemset-vx.S: Move to ... * sysdeps/s390/wmemset-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wmemset.c: Move to ... * sysdeps/s390/wmemset.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wmemset.h: New file. --- sysdeps/s390/Makefile | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'sysdeps/s390/Makefile') diff --git a/sysdeps/s390/Makefile b/sysdeps/s390/Makefile index 17aabf328b..ae2ae3d2ea 100644 --- a/sysdeps/s390/Makefile +++ b/sysdeps/s390/Makefile @@ -99,5 +99,6 @@ sysdep_routines += wcslen wcslen-vx wcslen-c \ wcsspn wcsspn-vx wcsspn-c \ wcspbrk wcspbrk-vx wcspbrk-c \ wcscspn wcscspn-vx wcscspn-c \ - wmemchr wmemchr-vx wmemchr-c + wmemchr wmemchr-vx wmemchr-c \ + wmemset wmemset-vx wmemset-c endif -- cgit 1.4.1
