From 0f042c67a04d5d0c8f879c27d651a7ed5aa6566f Mon Sep 17 00:00:00 2001 From: Andreas Krebbel Date: Thu, 22 Oct 2015 10:11:07 +0200 Subject: S/390: ifunc: Fix PR18841. In order to get the ifunc relocs properly sorted the correct class needs to be returned. The code mimics what has been done for x86. bfd/ChangeLog: PR ld/18841 * elf32-s390.c (elf_s390_reloc_type_class): Return reloc_class_ifunc for ifunc symbols. * elf64-s390.c (elf_s390_reloc_type_class): Likewise. --- bfd/elf32-s390.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'bfd/elf32-s390.c') diff --git a/bfd/elf32-s390.c b/bfd/elf32-s390.c index 85ac298..b1f9dbc 100644 --- a/bfd/elf32-s390.c +++ b/bfd/elf32-s390.c @@ -3805,6 +3805,23 @@ elf_s390_reloc_type_class (const struct bfd_link_info *info ATTRIBUTE_UNUSED, const asection *rel_sec ATTRIBUTE_UNUSED, const Elf_Internal_Rela *rela) { + bfd *abfd = info->output_bfd; + const struct elf_backend_data *bed = get_elf_backend_data (abfd); + struct elf_s390_link_hash_table *htab = elf_s390_hash_table (info); + unsigned long r_symndx = ELF32_R_SYM (rela->r_info); + Elf_Internal_Sym sym; + + if (htab->elf.dynsym == NULL + || !bed->s->swap_symbol_in (abfd, + (htab->elf.dynsym->contents + + r_symndx * bed->s->sizeof_sym), + 0, &sym)) + abort (); + + /* Check relocation against STT_GNU_IFUNC symbol. */ + if (ELF_ST_TYPE (sym.st_info) == STT_GNU_IFUNC) + return reloc_class_ifunc; + switch ((int) ELF32_R_TYPE (rela->r_info)) { case R_390_RELATIVE: -- cgit v1.1
