we do not need to copy a reloc against a global symbol which is
defined in an object we are including in the link (i.e., DEF_REGULAR
is set). At this point we have not seen all the input files, so it
is possible that DEF_REGULAR is not set now but will be set later (it
is never cleared). In case of a weak definition, DEF_REGULAR may be
cleared later by a strong definition in a shared library. We account
for that possibility below by storing information in the relocs_copied
field of the hash table entry. A similar situation occurs when
creating shared libraries and symbol visibility changes render the
symbol local.
If on the other hand, we are creating an executable, we may need to
keep relocations for symbols satisfied by a dynamic library if we
manage to avoid copy relocs for the symbol.

x86: Remove _bfd_{i386,x86_64}_elf_convert_load Instead of converting GOT relocations when sizing dynamic sections, we convert GOT relocations during relocation check. Add a field, local_ref, to elf_x86_link_hash_entry to indicate if symbol references are always local with a new function to check if symbol references are always local, which works in check_relocs. * elf32-i386.c (elf_i386_convert_load_reloc): Add an argument, r_type_p.

x86: Properly handle __ehdr_start After _bfd_i386_elf_convert_load and _bfd_x86_64_elf_convert_load are removed, elf_i386_convert_load_reloc and elf_x86_64_convert_load_reloc see __ehdr_start as an undefined symbol when they are called from check_relocs to convert GOT relocations against local symbols. But __ehdr_start will be defined as a hidden symbol by linker at the later stage if it is referenced. This patch marks __ehdr_start as a defined local symbol at the start of check_relocs if it is referenced and not defined. bfd/ PR ld/22115 * elf32-i386.c (elf_i386_convert_load_reloc): Check linker_def.

x86: Add _bfd_x86_elf_size_dynamic_sections elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are very similar, except for the followings: 1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH. elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE for both i386 and x86-64. 2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only if target_id == X86_64_ELF_DATA. 3. x86-64 has if (s != htab->elf.srelplt) s->reloc_count = 0; and i386 has s->reloc_count = 0; i386 did have if (s != htab->srelplt) s->reloc_count = 0; in the original commit: commit 67a4f2b710581acc83afecff55424af285ecbc28 Author: Alexandre Oliva <aoliva@redhat.com> Date: Wed Jan 18 21:07:51 2006 +0000 But it was removed by commit 5ae0bfb60a576344d7f701605346282c1144499e Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Tue Feb 28 07:16:12 2006 +0000 bfd/ * elf32-i386.c (elf_i386_link_hash_table): Add next_tls_desc_index.

(elf_i386_finish_dynamic_symbol): Put R_386_IRELATIVE after R_386_JUMP_SLOT. changed it back to use reloc_count again. So it is correct to use if (s != htab->elf.srelplt) s->reloc_count = 0; for both i386 and x86-64 now. 4. i386 and x86-64 use different DT_XXXs. They are handled by adding them to elf_x86_link_hash_table.

x86: Add _bfd_x86_elf_size_dynamic_sections elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are very similar, except for the followings: 1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH. elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE for both i386 and x86-64. 2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only if target_id == X86_64_ELF_DATA. 3. x86-64 has if (s != htab->elf.srelplt) s->reloc_count = 0; and i386 has s->reloc_count = 0; i386 did have if (s != htab->srelplt) s->reloc_count = 0; in the original commit: commit 67a4f2b710581acc83afecff55424af285ecbc28 Author: Alexandre Oliva <aoliva@redhat.com> Date: Wed Jan 18 21:07:51 2006 +0000 But it was removed by commit 5ae0bfb60a576344d7f701605346282c1144499e Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Tue Feb 28 07:16:12 2006 +0000 bfd/ * elf32-i386.c (elf_i386_link_hash_table): Add next_tls_desc_index.

(elf_i386_size_dynamic_sections): Set next_tls_desc_index and next_irelative_index from reloc_count. (elf_i386_finish_dynamic_symbol): Put R_386_IRELATIVE after R_386_JUMP_SLOT. changed it back to use reloc_count again. So it is correct to use if (s != htab->elf.srelplt) s->reloc_count = 0; for both i386 and x86-64 now. 4. i386 and x86-64 use different DT_XXXs. They are handled by adding them to elf_x86_link_hash_table. With these changes, we can share _bfd_x86_elf_size_dynamic_sections in elf32-i386.c and elf64-x86-64.c. * elf32-i386.c (elf_i386_convert_load): Renamed to ... (_bfd_i386_elf_convert_load): This.
