Jens Remus 6f8b365b65 s390: Avoid reloc overflows on undefined weak symbols (cont) ... This complements and reuses logic from Andreas Krebbel's commit 896a639bab ("s390: Avoid reloc overflows on undefined weak symbols"). Replace relative long addressing instructions of weak symbols, which will definitely resolve to zero, with either a load address of 0 or a a trapping insn. This prevents the PLT32DBL relocation from overflowing in case the binary will be loaded at 4GB or more. bfd/ * elf64-s390.c (elf_s390_relocate_section): Replace instructions using undefined weak symbols with relative addressing to avoid relocation overflows. ld/ * testsuite/ld-s390/s390.exp: Add new test. * testsuite/ld-s390/weakundef-2.s: New test. * testsuite/ld-s390/weakundef-2.dd: Likewise.
