From 581a051c2e09a847332d4750f6132de0f0ad15b6 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 18 Dec 2018 13:57:16 +0100 Subject: S390: Refactor memchr ifunc handling. The ifunc handling for memchr is adjusted in order to omit ifunc variants if those will never be used as the minimum architecture level already supports newer CPUs by default. Glibc internal calls will then also use the "newer" ifunc variant. Note: The fallback s390-32/s390-64 ifunc variants with srst instruction are now moved to the unified memchr-z900.S file which can be used for 31/64bit. The s390-32/s390-64 files multiarch/memchr.c and memchr.S are deleted. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove memchr variants. * sysdeps/s390/Makefile (sysdep_routines): Add memchr variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for memchr. * sysdeps/s390/multiarch/memchr-vx.S: Move to ... * sysdeps/s390/memchr-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/memchr.c: Move to ... * sysdeps/s390/memchr.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-memchr.h: New file. * sysdeps/s390/s390-64/memchr.S: Move to ... * sysdeps/s390/memchr-z900.S: ... here and adjust to be usable for 31/64bit and ifunc handling. * sysdeps/s390/s390-32/multiarch/memchr.c: Delete file. * sysdeps/s390/s390-64/multiarch/memchr.c: Likewise. * sysdeps/s390/s390-32/memchr.S: Likewise. --- ChangeLog | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 699cc4ce2e..ea704f6d13 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,22 @@ +2018-12-18 Stefan Liebler + + * sysdeps/s390/multiarch/Makefile + (sysdep_routines): Remove memchr variants. + * sysdeps/s390/Makefile (sysdep_routines): Add memchr variants. + * sysdeps/s390/multiarch/ifunc-impl-list.c + (__libc_ifunc_impl_list): Refactor ifunc handling for memchr. + * sysdeps/s390/multiarch/memchr-vx.S: Move to ... + * sysdeps/s390/memchr-vx.S: ... here and adjust ifunc handling. + * sysdeps/s390/multiarch/memchr.c: Move to ... + * sysdeps/s390/memchr.c: ... here and adjust ifunc handling. + * sysdeps/s390/ifunc-memchr.h: New file. + * sysdeps/s390/s390-64/memchr.S: Move to ... + * sysdeps/s390/memchr-z900.S: ... here and adjust to be usable + for 31/64bit and ifunc handling. + * sysdeps/s390/s390-32/multiarch/memchr.c: Delete file. + * sysdeps/s390/s390-64/multiarch/memchr.c: Likewise. + * sysdeps/s390/s390-32/memchr.S: Likewise. + 2018-12-18 Stefan Liebler * sysdeps/s390/multiarch/Makefile -- cgit 1.4.1
