* Fix ifunc-impl-list.c build for s390Joseph Myers2023-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | Builds for s390 recently started failing with: ../sysdeps/s390/multiarch/ifunc-impl-list.c: In function '__libc_ifunc_impl_list': ../sysdeps/s390/multiarch/ifunc-impl-list.c:83:21: error: unused variable 'dl_hwcap' [-Werror=unused-variable] 83 | unsigned long int dl_hwcap = features->hwcap; | ^~~~~~~~ https://sourceware.org/pipermail/libc-testresults/2023q1/010855.html Add __attribute__ ((unused)) as already done for another variable there. Tested with build-many-glibcs.py (compilers and glibcs) for s390x-linux-gnu and s390-linux-gnu. Note: s390x-linux-gnu-O3 started failing with a different error earlier; that problem may still need to be fixed after this fix is in. https://sourceware.org/pipermail/libc-testresults/2023q1/010829.html
* S390: Influence hwcaps/stfle via GLIBC_TUNABLES.Stefan Liebler2023-02-072-41/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the option to influence hwcaps and stfle bits used by the s390 specific ifunc-resolvers. The currently x86-specific tunable glibc.cpu.hwcaps is also used on s390x to achieve the task. In addition the user can also set a CPU arch-level like z13 instead of single HWCAP and STFLE features. Note that the tunable only handles the features which are really used in the IFUNC-resolvers. All others are ignored as the values are only used inside glibc. Thus we can influence: - HWCAP_S390_VXRS (z13) - HWCAP_S390_VXRS_EXT (z14) - HWCAP_S390_VXRS_EXT2 (z15) - STFLE_MIE3 (z15) The influenced hwcap/stfle-bits are stored in the s390-specific cpu_features struct which also contains reserved fields for future usage. The ifunc-resolvers and users of stfle bits are adjusted to use the information from cpu_features struct. On 31bit, the ELF_MACHINE_IRELATIVE macro is now also defined. Otherwise the new ifunc-resolvers segfaults as they depend on the not yet processed_rtld_global_ro@GLIBC_PRIVATE relocation.

* elf: Remove -fno-tree-loop-distribute-patterns usage on dl-supportAdhemerval Zanella2022-10-101-0/+29
| | | | | | | | | | | | | | Besides the option being gcc specific, this approach is still fragile and not future proof since we do not know if this will be the only optimization option gcc will add that transforms loops to memset (or any libcall). This patch adds a new header, dl-symbol-redir-ifunc.h, that can b used to redirect the compiler generated libcalls to port the generic memset implementation if required. Checked on x86_64-linux-gnu and aarch64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* S390: Fix werror=unused-variable in ifunc-impl-list.c.Stefan Liebler2022-08-181-1/+3
| | | | | | | | | | If the architecture level set is high enough, no IFUNCs are used at all and the variable i would be unused. Then the build fails with: ../sysdeps/s390/multiarch/ifunc-impl-list.c: In function ‘__libc_ifunc_impl_list’: ../sysdeps/s390/multiarch/ifunc-impl-list.c:76:10: error: unused variable ‘i’ [-Werror=unused-variable] 76 | size_t i = max; | ^ cc1: all warnings being treated as errors
* Add bounds check to __libc_ifunc_impl_listWilco Dijkstra2022-06-101-7/+2
| | | | | | | | | | | | Add a proper bounds check to __libc_ifunc_impl_list. This makes MAX_IFUNC redundant and fixes several targets that will write outside the array. To avoid unnecessary large diffs, pass the maximum in the argument 'i' to IFUNC_IMPL_ADD - 'max' can be used in new ifunc definitions and existing ones can be updated if desired. Passes buildmanyglibc. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* S390: Also check vector support in memmove ifunc-selector [BZ #27511]Stefan Liebler2021-03-261-1/+2
| | | | | | | | | | | | | | | The arch13 memmove variant is currently selected by the ifunc selector if the Miscellaneous-Instruction-Extensions Facility 3 facility bit is present, but the function is also using vector instructions. If the vector support is not present, one is receiving an operation exception. Therefore this patch also checks for vector support in the ifunc selector and in ifunc-impl-list.c. Just to be sure, the configure check is now also testing an arch13 vector instruction and an arch13 Miscellaneous-Instruction-Extensions Facility 3 instruction.

Note: The fallback s390-32/s390-64 ifunc variants with clst instruction are now moved to the unified strcmp-z900.S file which can be used for 31/64bit. The s390-32/s390-64 files multiarch/strcmp.c and strcmp.S are deleted. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove strcmp variants. * sysdeps/s390/Makefile (sysdep_routines): Add strcmp variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for strcmp. * sysdeps/s390/multiarch/strcmp-vx.S: Move to ... * sysdeps/s390/strcmp-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/strcmp.c: Move to ... * sysdeps/s390/strcmp.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-strcmp.h: New file. * sysdeps/s390/s390-64/strcmp.S: Move to ... * sysdeps/s390/strcmp-z900.S: ... here and adjust to be usable for 31/64bit and ifunc handling. * sysdeps/s390/s390-32/multiarch/strcmp.c: Delete file. * sysdeps/s390/s390-64/multiarch/strcmp.c: Likewise. * sysdeps/s390/s390-32/strcmp.S: Likewise.
