From c7e7cd266ed123b6dfb722f599934ca5dcfd3e93 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:18 +0100 Subject: S390: Refactor wcsnlen ifunc handling. The ifunc handling for wcsnlen 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 wcsnlen variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcsnlen variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcsnlen. * sysdeps/s390/multiarch/wcsnlen-c.c: Move to ... * sysdeps/s390/wcsnlen-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsnlen-vx.S: Move to ... * sysdeps/s390/wcsnlen-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsnlen.c: Move to ... * sysdeps/s390/wcsnlen.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcsnlen.h: New file. --- ChangeLog | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 17558e4..128e0fc 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,6 +1,21 @@ 2018-12-18 Stefan Liebler * sysdeps/s390/multiarch/Makefile + (sysdep_routines): Remove wcsnlen variants. + * sysdeps/s390/Makefile (sysdep_routines): Add wcsnlen variants. + * sysdeps/s390/multiarch/ifunc-impl-list.c + (__libc_ifunc_impl_list): Refactor ifunc handling for wcsnlen. + * sysdeps/s390/multiarch/wcsnlen-c.c: Move to ... + * sysdeps/s390/wcsnlen-c.c: ... here and adjust ifunc handling. + * sysdeps/s390/multiarch/wcsnlen-vx.S: Move to ... + * sysdeps/s390/wcsnlen-vx.S: ... here and adjust ifunc handling. + * sysdeps/s390/multiarch/wcsnlen.c: Move to ... + * sysdeps/s390/wcsnlen.c: ... here and adjust ifunc handling. + * sysdeps/s390/ifunc-wcsnlen.h: New file. + +2018-12-18 Stefan Liebler + + * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wcslen variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcslen variants. * sysdeps/s390/multiarch/ifunc-impl-list.c -- cgit v1.1
