When dereferencing a GOT slot with lgrl or lg we rewrite this using larl to get rid of the extra memory access. However, we cannot do this for: - symbols marked for absolute addressing - symbols at odd addresses (larl can handle only even addresses) Fixed with the attached patch. bfd/ChangeLog: 2018-09-17 Andreas Krebbel <krebbel@linux.ibm.com> * elf64-s390.c (elf_s390_relocate_section): Prevent rewriting of GOT accesses with larl for ABS or misaligned symbols. ld/ChangeLog: 2018-09-17 Andreas Krebbel <krebbel@linux.ibm.com> * testsuite/ld-s390/gotreloc-1.s: Add tests for ABS and misaligned symbol. Move variables into data section. Make bar 8 bytes wide. * testsuite/ld-s390/gotreloc-1.ver: Make misaligned_sym resolve locally. * testsuite/ld-s390/gotreloc_31-1.dd: Adjust patterns. * testsuite/ld-s390/gotreloc_64-norelro-1.dd: Likewise. * testsuite/ld-s390/gotreloc_64-relro-1.dd: Likewise.
