2023-07-10sysdeps/s390: Exclude fortified routines from being built with _FORTIFY_SOURCEFrédéric Bérat1-0/+20
Depending on build configuration, the [routine]-c.c files may be chosen to provide fortified routines implementation. While [routines].c implementation were automatically excluded, the [routines]-c.c ones were not. This patch fixes that by adding these file to the list to be filtered.
2022-08-25s390: Move hwcaps/platform names out of _rtld_global_roFlorian Weimer1-0/+2
Changes to these arrays are often backported to stable releases, but additions to these arrays shift the offsets of the following _rltd_global_ro members, thus breaking the GLIBC_PRIVATE ABI. Obviously, this change is itself an internal ABI break, but at least it will avoid further ABI breaks going forward. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2022-02-23s390: Remove bzero optimizationsAdhemerval Zanella1-1/+1
The symbol is not present in current POSIX specification and compiler already generates memset call.
2021-06-09iconvdata: Move gconv-modules configuration to gconv-modules.confSiddhesh Poyarekar1-2/+14
Move all gconv-modules configuration files to gconv-modules.conf. That is, the S390 extensions now become gconv-modules-s390.conf. Move both configuration files into gconv-modules.d. Now GCONV_PATH/gconv-modules is read only for backward compatibility for third-party gconv modules directories. Reviewed-by: DJ Delorie <dj@redhat.com>
2019-03-22S390: Add arch13 memmem ifunc variant.Stefan Liebler1-1/+1
This patch introduces the new arch13 ifunc variant for memmem. For needles longer than 9 bytes it is relying on the common-code implementation. For shorter needles it is using the new vstrs instruction which is able to search a substring within a vector register. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add memmem-arch13. * sysdeps/s390/ifunc-memmem.h (HAVE_MEMMEM_ARCH13, MEMMEM_ARCH13, MEMMEM_Z13_ONLY_USED_AS_FALLBACK, HAVE_MEMMEM_IFUNC_AND_ARCH13_SUPPORT): New defines. * sysdeps/s390/memmem-arch13.S: New file. * sysdeps/s390/memmem-vx.c: Omit GI symbol for z13 memmem ifunc variant if it is only used as fallback. * sysdeps/s390/memmem.c (memmem): Add arch13 variant in ifunc selector. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variant for arch13 memmem.

2018-12-18S390: Add z13 memmove ifunc variant.Stefan Liebler1-1/+2
This patch introduces a z13 specific ifunc variant for memmove. As the common code implementation, it checks if we can copy from the beginning to the end - with z196 memcpy implementation - or if we have to copy from the end to the beginning. The latter case is done by using vector load/store instructions. If vector instructions are not available, the common-code is used as fallback. Therefore it is implemented in memmove-c with a different name. Furthermore the ifunc logic decides if we need the common-code implementation at all. If vector instructions are supported due to the minimum architecture level set we can skip the common-code ifunc variant. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add memmove-c. * sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_IFUNC, HAVE_MEMMOVE_IFUNC_AND_VX_SUPPORT, MEMMOVE_DEFAULT, HAVE_MEMMOVE_C, MEMMOVE_C, HAVE_MEMMOVE_Z13, MEMMOVE_Z13): New defines. * sysdeps/s390/memcpy-z900.S: Add z13 memmove implementation. * sysdeps/s390/memmove-c.c: New file. * sysdeps/s390/memmove.c: Likewise. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variants for memmove.
2018-12-18S390: Refactor memcpy/mempcpy ifunc handling.Stefan Liebler1-1/+2
This patch moves all ifunc variants for memcpy/mempcpy to sysdeps/s390/memcpy-z900.S. The configure-check/preprocessor logic in sysdeps/s390/ifunc-memcpy.h decides if ifunc is needed at all and which ifunc variants should be available. E.g. if the compiler/assembler already supports z196 by default, the older ifunc variants are not included. If we only need the newest ifunc variant, then we can skip ifunc at all. Therefore the ifunc-resolvers and __libc_ifunc_impl_list are adjusted in order to handle only the available ifunc variants. ChangeLog: * sysdeps/s390/ifunc-memcpy.h: New File. * sysdeps/s390/memcpy.S: Move to ... * sysdeps/s390/memcpy-z900.S ... here. Move implementations from memcpy-s390x.s to here. * sysdeps/s390/multiarch/memcpy-s390x.S: Delete File. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove memcpy/mempcpy variants. * sysdeps/s390/Makefile (sysdep_routines): Add memcpy/mempcpy variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Adjust ifunc variants for memcpy and mempcpy. * sysdeps/s390/multiarch/memcpy.c: Move ifunc resolver to ... * sysdeps/s390/memcpy.c: ... here. Adjust ifunc variants for memcpy. * sysdeps/s390/multiarch/mempcpy.c: Move to ... * sysdeps/s390/mempcpy.c: ... here. Adjust ifunc variants for mempcpy. * sysdeps/s390/mempcpy.S: Delete file.
