There is some attempt to make this function usable for many architectures, both USE_REL and USE_RELA ['twould be nice if such a critter existed], if only to serve as a learning tool. The RELOCATE_SECTION function is called by the new ELF backend linker to handle the relocations for a section. The relocs are always passed as Rela structures; if the section actually uses Rel structures, the r_addend field will always be zero. This function is responsible for adjusting the section contents as necessary, and (if using Rela relocs and generating a relocatable output file) adjusting the reloc addend as necessary. This function does not have to worry about setting the reloc address or the reloc symbol index. LOCAL_SYMS is a pointer to the swapped in local symbols. LOCAL_SECTIONS is an array giving the section in the input file corresponding to the st_shndx field of each local symbol. The global hash table entry for the global symbols can be found via elf_sym_hashes (input_bfd). When generating relocatable output, this function must handle STB_LOCAL/STT_SECTION symbols specially. The output symbol is going to be the section symbol corresponding to the output section, which means that the addend must be adjusted accordingly. */ static bfd_boolean mep_elf_relocate_section (bfd * output_bfd ATTRIBUTE_UNUSED, struct bfd_link_info * info, bfd * input_bfd, asection * input_section, bfd_byte * contents, Elf_Internal_Rela * relocs, Elf_Internal_Sym * local_syms, asection ** local_sections) { Elf_Internal_Shdr * symtab_hdr; struct elf_link_hash_entry ** sym_hashes; Elf_Internal_Rela * rel; Elf_Internal_Rela * relend; symtab_hdr = & elf_tdata (input_bfd)->symtab_hdr; sym_hashes = elf_sym_hashes (input_bfd); relend = relocs + input_section->reloc_count; mep_info = info; for (rel = relocs; rel < relend; rel ++) { reloc_howto_type * howto; unsigned long r_symndx; Elf_Internal_Sym * sym; asection * sec; struct elf_link_hash_entry * h; bfd_vma relocation; bfd_reloc_status_type r; const char * name = NULL; int r_type; r_type = ELF32_R_TYPE (rel->r_info); r_symndx = ELF32_R_SYM (rel->r_info); howto = mep_elf_howto_table + ELF32_R_TYPE (rel->r_info); h = NULL; sym = NULL; sec = NULL; if (r_symndx < symtab_hdr->sh_info) { sym = local_syms + r_symndx; sec = local_sections [r_symndx]; relocation = _bfd_elf_rela_local_sym (output_bfd, sym, &sec, rel); name = bfd_elf_string_from_elf_section (input_bfd, symtab_hdr->sh_link, sym->st_name); name = (name == NULL) ? bfd_section_name (input_bfd, sec) : name; } else { bfd_boolean warned, unresolved_reloc; RELOC_FOR_GLOBAL_SYMBOL(info, input_bfd, input_section, rel, r_symndx, symtab_hdr, sym_hashes, h, sec, relocation, unresolved_reloc, warned); name = h->root.root.string; } if (sec != NULL && elf_discarded_section (sec)) RELOC_AGAINST_DISCARDED_SECTION (info, input_bfd, input_section, rel, relend, howto, contents); if (info->relocatable) continue; if (r_type == R_RELC) r = bfd_elf_perform_complex_relocation (input_bfd, input_section, contents, rel, relocation); else r = mep_final_link_relocate (howto, input_bfd, input_section, contents, rel, relocation); if (r != bfd_reloc_ok) { const char * msg = (const char *) NULL; switch (r) { case bfd_reloc_overflow: r = info->callbacks->reloc_overflow (info, (h ? &h->root : NULL), name, howto->name, (bfd_vma) 0, input_bfd, input_section, rel->r_offset); break; case bfd_reloc_undefined: r = info->callbacks->undefined_symbol (info, name, input_bfd, input_section, rel->r_offset, TRUE); break; case bfd_reloc_outofrange: msg = _("internal error: out of range error"); break; case bfd_reloc_notsupported: msg = _("internal error: unsupported relocation error"); break; case bfd_reloc_dangerous: msg = _("internal error: dangerous relocation"); break; default: msg = _("internal error: unknown error"); break; } if (msg) r = info->callbacks->warning (info, msg, name, input_bfd, input_section, rel->r_offset); if (! r) return FALSE; } } if (warn_tp) info->callbacks->undefined_symbol (info, "__tpbase", input_bfd, input_section, warn_tp-1, TRUE); if (warn_sda) info->callbacks->undefined_symbol (info, "__sdabase", input_bfd, input_section, warn_sda-1, TRUE); if (warn_sda || warn_tp) return FALSE; return TRUE; } /* Function to set the ELF flag bits. */ static bfd_boolean mep_elf_set_private_flags (bfd * abfd, flagword flags) { elf_elfheader (abfd)->e_flags = flags; elf_flags_init (abfd) = TRUE; return TRUE; } static bfd_boolean mep_elf_copy_private_bfd_data (bfd * ibfd, bfd * obfd) { if (bfd_get_flavour (ibfd) != bfd_target_elf_flavour || bfd_get_flavour (obfd) != bfd_target_elf_flavour) return TRUE; elf_elfheader (obfd)->e_flags = elf_elfheader (ibfd)->e_flags; elf_flags_init (obfd) = TRUE; /* Copy object attributes. */ _bfd_elf_copy_obj_attributes (ibfd, obfd); return TRUE; } /* Merge backend specific data from an object file to the output object file when linking. */ static bfd_boolean mep_elf_merge_private_bfd_data (bfd * ibfd, bfd * obfd) { static bfd *last_ibfd = 0; flagword old_flags, new_flags; flagword old_partial, new_partial; /* Check if we have the same endianness. */ if (_bfd_generic_verify_endian_match (ibfd, obfd) == FALSE) return FALSE; new_flags = elf_elfheader (ibfd)->e_flags; old_flags = elf_elfheader (obfd)->e_flags; #ifdef DEBUG _bfd_error_handler ("%B: old_flags = 0x%.8lx, new_flags = 0x%.8lx, init = %s", ibfd, old_flags, new_flags, elf_flags_init (obfd) ?
