From 8e87c1f6d45a63dc2175825c2dc5d66192a13aab Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:23 +0100 Subject: S390: Refactor wcspbrk ifunc handling. The ifunc handling for wcspbrk 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 wcspbrk variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcspbrk variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcspbrk. * sysdeps/s390/multiarch/wcspbrk-c.c: Move to ... * sysdeps/s390/wcspbrk-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcspbrk-vx.S: Move to ... * sysdeps/s390/wcspbrk-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcspbrk.c: Move to ... * sysdeps/s390/wcspbrk.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcspbrk.h: New file. --- ChangeLog | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 30976db77d..f199133f1e 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,18 @@ +2018-12-18 Stefan Liebler + + * sysdeps/s390/multiarch/Makefile + (sysdep_routines): Remove wcspbrk variants. + * sysdeps/s390/Makefile (sysdep_routines): Add wcspbrk variants. + * sysdeps/s390/multiarch/ifunc-impl-list.c + (__libc_ifunc_impl_list): Refactor ifunc handling for wcspbrk. + * sysdeps/s390/multiarch/wcspbrk-c.c: Move to ... + * sysdeps/s390/wcspbrk-c.c: ... here and adjust ifunc handling. + * sysdeps/s390/multiarch/wcspbrk-vx.S: Move to ... + * sysdeps/s390/wcspbrk-vx.S: ... here and adjust ifunc handling. + * sysdeps/s390/multiarch/wcspbrk.c: Move to ... + * sysdeps/s390/wcspbrk.c: ... here and adjust ifunc handling. + * sysdeps/s390/ifunc-wcspbrk.h: New file. + 2018-12-18 Stefan Liebler * sysdeps/s390/multiarch/Makefile -- cgit 1.4.1
