* elf32-i386.c (elf_i386_discard_copies): Rename to
discard_copies, and use elf_link_hash_entry arg rather than elf_i386_link_hash_entry. (elf_i386_link_hash_traverse): Delete. (elf_i386_size_dynamic_sections): Adjust call to discard_copies. Tidy sizing of dynamic sections. (elf_i386_check_relocs <R_386_32, R_386_PC32>): Reference count possible .plt entries. (elf_i386_gc_sweep_hook): Likewise. (elf_i386_adjust_dynamic_symbol): Discard .plt entries for everything with plt.refcount <= 0. * elf32-i386.c (elf_i386_check_relocs): Don't allocate .got and .relgot space here. (elf_i386_gc_sweep_hook): ..and no need to deallocate here.. (elf32_hppa_adjust_dynamic_symbol): ..and don't allocate .plt and .rel.plt here.. (allocate_plt_and_got): ..instead do it all here. New function. (elf_i386_size_dynamic_sections): Allocate local .got space and call allocate_plt_and_got. No need to zap .relgot if not dynamic. (bfd_elf32_bfd_final_link): Delete. (ie. use regular final link rather than gc variety). (WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define. (elf_i386_relocate_section): Use it here and correct handling of R_386_GOT32. Provide section and offset for "unresolvable relocation" error message. (elf_i386_finish_dynamic_symbol): Correct handling of R_386_GOT32. * elf32-i386.c (struct elf_i386_link_hash_table): Add sgot, sgotplt, srelgot, splt, srelplt, sdynbss, srelbss fields. (elf_i386_link_hash_table_create): Init them. (create_got_section): New function. (elf_i386_create_dynamic_sections): New function. (elf_backend_create_dynamic_sections): Set to above. (elf_i386_check_relocs): Use shortcuts from hash table rather than calling bfd_get_section_by_name. (elf_i386_gc_sweep_hook): Likewise. (elf_i386_adjust_dynamic_symbol): Likewise. (elf_i386_size_dynamic_sections): Likewise. (elf_i386_relocate_section): Likewise. (elf_i386_finish_dynamic_sections): Likewise.
