* elf64-x86-64.c: Major rework that introduces all recent changes to the x86-64 backend. Get a closer match to elf32-i386. (struct elf64_x86_64_dyn_relocs): Rename from elf64_x86_64_pcrel_relocs_copied, add additional fields. Change all users. (struct elf64_x86_64_link_hash_table): Add short cuts to some sections. (link_hash_newfunc): Rename from elf64_x86_64_link_hash_newfunc, remove casts, initialize new hash members. (create_got_section): New. (elf64_x86_64_create_dynamic_sections): New. (elf64_x86_64_copy_indirect_symbol): New. (elf64_x86_64_check_relocs): Don't allocate space for dynamic relocs, .got or .relgot here but do it in allocate_dynrelocs. Reference count possible .plt and .got entries. Don't test input section SEC_READONLY here to try to avoid copy relocs, and keep dyn_relocs regardless of ELF_LINK_NON_GOT_REF. Don't set DF_TEXTREL here. Delay setting of variables until needed. Cache pointer to "sreloc" section in elf_section_data. Tweak condition under which .got created. Report files with bad relocation section names. (elf64_x86_64_gc_sweep_hook): Sweep dyn_relocs and local_dynrel. Reference count possible .plt entries. Don't deallocate .got and .relgot space here. (elf64_x86_64_adjust_dynamic_symbol): Handle nocopyreloc. Don't do copy reloc processing for weakdefs. Remove redundant casts and aborts. Delay setting of vars until needed. Move creation of dynamic symbols and allocation of .plt and .rela.plt to allocate_dynrelocs. Replace BFD_ASSERT with abort. (WILL_CALL_FINISH_DYNAMIC_SYMBOL): New. (allocate_dynrelocs): New. (readonly_dynrelocs): New. (elf64_x86_64_size_dynamic_sections): Call readonly_dynrelocs. Allocate space for dyn relocs. Replace BFD_ASSERT with abort. Zero out the dynamic allocated content space. (elf64_x86_64_discard_copies): Removed. (elf64_x86_64_relocate_section): Make use of dynamic section short-cuts. Localise vars, and delay setting. Better error reporting, replace BFD_ASSERT with abort. Check ELF_LINK_HASH_DEF_DYNAMIC to see if a symbol is not defined in the regular object file and tread the weak definition as the normal one. Don't discard relocs for undefweak or undefined symbols and check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy relocs. (elf64_x86_64_finish_dynamic_symbol): Don't copy relocs for symbols that have been forced local. Use same test to decide if we can use a relative reloc for got as relocate_section. Expand SHN_UNDEF comment. Move expressions out of function calls. Replace BFD_ASSERT with abort. (bfd_elf64_bfd_final_link): Removed. (elf_backend_copy_indirect_symbol): Define.

Reference count possible .plt and .got entries. Don't test input section SEC_READONLY here to try to avoid copy relocs, and keep dyn_relocs regardless of ELF_LINK_NON_GOT_REF. Don't set DF_TEXTREL here. Delay setting of variables until needed. Cache pointer to "sreloc" section in elf_section_data. Tweak condition under which .got created.

Don't discard relocs for undefweak or undefined symbols and check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy relocs. (elf64_x86_64_finish_dynamic_symbol): Don't copy relocs for symbols that have been forced local. Use same test to decide if we can use a relative reloc for got as relocate_section.

* elf64-x86-64.c: Major rework that introduces all recent changes to the x86-64 backend. Get a closer match to elf32-i386.

Reference count possible .plt and .got entries. Don't test input section SEC_READONLY here to try to avoid copy relocs, and keep dyn_relocs regardless of ELF_LINK_NON_GOT_REF. Don't set DF_TEXTREL here. Delay setting of variables until needed. Cache pointer to "sreloc" section in elf_section_data. Tweak condition under which .got created. Report files with bad relocation section names. (elf64_x86_64_gc_sweep_hook): Sweep dyn_relocs and local_dynrel. Reference count possible .plt entries. Don't deallocate .got and .relgot space here. (elf64_x86_64_adjust_dynamic_symbol): Handle nocopyreloc. Don't do copy reloc processing for weakdefs. Remove redundant casts and aborts. Delay setting of vars until needed. Move creation of dynamic symbols and allocation of .plt and .rela.plt to allocate_dynrelocs. Replace BFD_ASSERT with abort. (WILL_CALL_FINISH_DYNAMIC_SYMBOL): New. (allocate_dynrelocs): New. (readonly_dynrelocs): New. (elf64_x86_64_size_dynamic_sections): Call readonly_dynrelocs. Allocate space for dyn relocs. Replace BFD_ASSERT with abort. Zero out the dynamic allocated content space.

Better error reporting, replace BFD_ASSERT with abort. Check ELF_LINK_HASH_DEF_DYNAMIC to see if a symbol is not defined in the regular object file and tread the weak definition as the normal one. Don't discard relocs for undefweak or undefined symbols and check !DEF_REGULAR as well as DEF_DYNAMIC in test for avoided copy relocs. (elf64_x86_64_finish_dynamic_symbol): Don't copy relocs for symbols that have been forced local. Use same test to decide if we can use a relative reloc for got as relocate_section. Expand SHN_UNDEF comment. Move expressions out of function calls. Replace BFD_ASSERT with abort. (bfd_elf64_bfd_final_link): Removed. (elf_backend_copy_indirect_symbol): Define.

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.

may need to keep relocations for symbols satisfied by a
