* S390: Refactor wmemchr ifunc handling.Stefan Liebler2018-12-181-166/+0
| | | | | | | | | | | | | | | | | | | | | | | The ifunc handling for wmemchr 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 wmemchr variants. * sysdeps/s390/Makefile (sysdep_routines): Add wmemchr variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wmemchr. * sysdeps/s390/multiarch/wmemchr-c.c: Move to ... * sysdeps/s390/wmemchr-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wmemchr-vx.S: Move to ... * sysdeps/s390/wmemchr-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wmemchr.c: Move to ... * sysdeps/s390/wmemchr.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wmemchr.h: New file.
