(ppc64_elf_relocate_section): Use them. Don't look for plt calls on R_PPC64_ADDR24 relocs. Require a nop or no link reg on plt call branches. Correct undefined weak destination. (ppc64_elf_func_desc_adjust): Always create at least one blr in .sfpr, and correct case where either only savef* or restf* is needed. Long branch stubs, multiple stub sections. * elf64-ppc.h (ppc64_elf_setup_section_lists): Declare. (ppc64_elf_next_input_section): Declare. * elf64-ppc.c: Move linker-only prototypes. (STUB_SUFFIX): Define. (enum ppc_stub_type): New. (struct ppc_stub_hash_entry): New. (struct ppc_branch_hash_entry): New. (struct ppc_link_hash_entry): Add stub_cache, oh. (struct ppc_link_hash_table): Add stub_hash_table etc. Remove sstub. Add sbrlt, srelbrlt, has_14bit_branch, stub_iteration. Rename plt_overflow to stub_error. (ppc_stub_hash_lookup): Define. (ppc_branch_hash_lookup): Define. (stub_hash_newfunc): New function. (branch_hash_newfunc): New function. (link_hash_newfunc): Init new fields. (ppc64_elf_link_hash_table_create): Likewise. (ppc64_elf_link_hash_table_free): New function. (ppc_stub_name): New function. (ppc_get_stub_entry): New function. (ppc_add_stub): New function. (create_linkage_sections): Use bfd_make_section_anyway. Create .branch_lt and .rela.branch_lt sections. Don't create .stub. (ppc64_elf_check_relocs): Set has_14bit_branch on R_PPC64_REL14*, and set up for plt call stubs. Link func and func desc syms. (ppc64_elf_gc_sweep_hook): Handle REL14* as per REL24. (func_desc_adjust): Avoid hash lookup when func desc sym available via shortcut, and set links when processing. (ppc64_elf_hide_symbol): Likewise. (allocate_dynrelocs): Don't allocate stub section here. (ppc64_elf_size_dynamic_sections): Handle sbrlt and srelbrlt. Remove sstub code. (ppc_type_of_stub): New function. (build_one_stub): Delete. (ppc_build_one_stub): New function. (ppc_size_one_stub): New function. (ppc64_elf_setup_section_lists): New function. (ppc64_elf_next_input_section): New function. (group_sections): New function. (get_local_syms): New function. (ppc64_elf_size_stubs): Rewrite. (ppc64_elf_build_stubs): Rewrite. (ppc64_elf_relocate_section): Look up stub entry for REL24 relocs. Don't propagate REL14* to dynamic objects. Look for long branch stubs if REL14* or REL24 relocs won't reach. (bfd_elf64_bfd_link_hash_table_free): Define.
