  "message": "s390: Do not rewrite insns and their relocs in linker if --no-relax\n\nUnder certain conditions the linker rewrites:\n- GOT access using lgrl to larl, changing the GOTENT to a PC32DBL reloc\n- GOT access using lg to larl, changing the GOT20 to a PC32DBL reloc\n- Relative long addressing instructions of weak symbols, which\n  definitively resolve to zero to either (1) load address of zero,\n  (2) a NOP, or (3) a trapping instruction, changing the relocation to\n  a NONE reloc.\n\nSuppress rewriting of non-TLS instructions and related relocations in\nlinker if option --no-relax is specified.  This aligns with LLVM linker\nbehavior on s390.\n\nLike x86-64 do not actually enable the linker relaxation option by\ndefault, as other targets would do using ENABLE_RELAXATION or\nTARGET_ENABLE_RELAXATION in their linker emulation scripts.  Instead\nperform linker instruction/relocation rewrites by default unless linker\noption --no-relax is explicitly specified by the user.  This ensures no\nfunctional change unless --no-relax is used.\n\nbfd/\n\t* elf64-s390.c (elf_s390_relocate_section): Do not rewrite\n\tnon-TLS instructions and related relocations if --no-relax.\n\t* elf32-s390.c (elf_s390_relocate_section): Likewise.\n\nld/testsuite/\n\t* ld-s390/s390.exp: New tests.  Same as gotreloc_*-1a and\n\tweakundef-*a, but with linker option --no-relax, to verify\n\tsuppression of linker non-TLS insn and reloc rewrites.\n\t* ld-s390/gotreloc_31-1b.dd: Likewise.\n\t* ld-s390/gotreloc_31-no-pie-1b.dd: Likewise.\n\t* ld-s390/gotreloc_64-no-pie-1b.dd: Likewise.\n\t* ld-s390/gotreloc_64-norelro-1b.dd: Likewise.\n\t* ld-s390/gotreloc_64-relro-1b.dd: Likewise.\n\t* ld-s390/weakundef-1b.d: Likewise.  Check for expected reloc\n\toverflows.\n\t* ld-s390/weakundef-2b.d: Likewise.\n\nSigned-off-by: Jens Remus \u003cjremus@linux.ibm.com\u003e\n",
