A relocation - for the GOT entry always has to be created, be it to offset a - private symbol by the section load address, be it to get the symbol - resolved dynamically. - - FUNCDESC GOT relocations require a GOT entry to be created, and - handled as if a FUNCDESC relocation was applied to the GOT entry in - an object file. - - FUNCDESC relocations referencing a symbol that turns out to NOT be - dynamic cause a private function descriptor to be created. The - FUNCDESC relocation then decays to a 32 relocation that points at - the private descriptor. If the symbol is dynamic, the FUNCDESC - relocation is propagated to the linker output, such that the - dynamic linker creates the canonical descriptor, pointing to the - dynamically-resolved definition of the function. - - Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic - symbols that are assigned to the same segment as the GOT, but we - can only check this later, after we know the complete set of - symbols defined and/or exported. - - FUNCDESC GOTOFF relocations require a function descriptor to be - created and, unless lazy binding is disabled or the symbol is not - dynamic, a lazy PLT entry. Since we can't tell at this point - whether a symbol is going to be dynamic, we have to decide later - whether to create a lazy PLT entry or bind the descriptor directly - to the private function. - - FUNCDESC_VALUE relocations are not supposed to be present in object - files, but they may very well be simply propagated to the linker - output, since they have no side effect. - - - A function descriptor always requires a FUNCDESC_VALUE relocation. - Whether it's in .plt.rel or not depends on whether lazy binding is - enabled and on whether the referenced symbol is dynamic. - - The existence of a lazy PLT requires the resolverStub lazy PLT - entry to be present. - - - As for assignment of GOT, PLT and lazy PLT entries, and private - descriptors, we might do them all sequentially, but we can do - better than that. For example, we can place GOT entries and - private function descriptors referenced using 12-bit operands - closer to the PIC register value, such that these relocations don't - overflow. Those that are only referenced with LO16 relocations - could come next, but we may as well place PLT-required function - descriptors in the 12-bit range to make them shorter. Symbols - referenced with LO16/HI16 may come next, but we may place - additional function descriptors in the 16-bit range if we can - reliably tell that we've already placed entries that are ever - referenced with only LO16. PLT entries are therefore generated as - small as possible, while not introducing relocation overflows in - GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be - generated before or after PLT entries, but not intermingled with - them, such that we can have more lazy PLT entries in range for a - branch to the resolverStub. The resolverStub should be emitted at - the most distant location from the first lazy PLT entry such that - it's still in range for a branch, or closer, if there isn't a need - for so many lazy PLT entries. Additional lazy PLT entries may be - emitted after the resolverStub, as long as branches are still in - range. If the branch goes out of range, longer lazy PLT entries - are emitted. - - We could further optimize PLT and lazy PLT entries by giving them - priority in assignment to closer-to-gr17 locations depending on the - number of occurrences of references to them (assuming a function - that's called more often is more important for performance, so its - PLT entry should be faster), or taking hints from the compiler. - Given infinite time and money... :-) */ - -static bfd_boolean -elf32_frv_check_relocs (abfd, info, sec, relocs) - bfd *abfd; - struct bfd_link_info *info; - asection *sec; - const Elf_Internal_Rela *relocs; -{ - Elf_Internal_Shdr *symtab_hdr; - struct elf_link_hash_entry **sym_hashes, **sym_hashes_end; - const Elf_Internal_Rela *rel; - const Elf_Internal_Rela *rel_end; - bfd *dynobj; - struct frvfdpic_relocs_info *picrel; - - if (info->relocatable) - return TRUE; - - symtab_hdr = &elf_tdata (abfd)->symtab_hdr; - sym_hashes = elf_sym_hashes (abfd); - sym_hashes_end = sym_hashes + symtab_hdr->sh_size/sizeof(Elf32_External_Sym); - if (!elf_bad_symtab (abfd)) - sym_hashes_end -= symtab_hdr->sh_info; - - dynobj = elf_hash_table (info)->dynobj; - rel_end = relocs + sec->reloc_count; - for (rel = relocs; rel < rel_end; rel++) - { - struct elf_link_hash_entry *h; - unsigned long r_symndx; - - r_symndx = ELF32_R_SYM (rel->r_info); - if (r_symndx < symtab_hdr->sh_info) - h = NULL; - else - { - h = sym_hashes[r_symndx - symtab_hdr->sh_info]; - while (h->root.type == bfd_link_hash_indirect - || h->root.type == bfd_link_hash_warning) - h = (struct elf_link_hash_entry *) h->root.u.i.link; - } - - switch (ELF32_R_TYPE (rel->r_info)) - { - case R_FRV_GETTLSOFF: - case R_FRV_TLSDESC_VALUE: - case R_FRV_GOTTLSDESC12: - case R_FRV_GOTTLSDESCHI: - case R_FRV_GOTTLSDESCLO: - case R_FRV_GOTTLSOFF12: - case R_FRV_GOTTLSOFFHI: - case R_FRV_GOTTLSOFFLO: - case R_FRV_TLSOFF: - case R_FRV_GOT12: - case R_FRV_GOTHI: - case R_FRV_GOTLO: - case R_FRV_FUNCDESC_GOT12: - case R_FRV_FUNCDESC_GOTHI: - case R_FRV_FUNCDESC_GOTLO: - case R_FRV_GOTOFF12: - case R_FRV_GOTOFFHI: - case R_FRV_GOTOFFLO: - case R_FRV_FUNCDESC_GOTOFF12: - case R_FRV_FUNCDESC_GOTOFFHI: - case R_FRV_FUNCDESC_GOTOFFLO: - case R_FRV_FUNCDESC: - case R_FRV_FUNCDESC_VALUE: - case R_FRV_TLSMOFF12: - case R_FRV_TLSMOFFHI: - case R_FRV_TLSMOFFLO: - case R_FRV_TLSMOFF: - if (!
