* elf64-ppc.c (struct ppc_dyn_relocs): New.
(IS_ABSOLUTE_RELOC): Define.
(struct ppc_link_hash_entry): New.
(struct ppc_link_hash_table): New.
(ppc_hash_table): Define.
(link_hash_newfunc): New function.
(ppc64_elf_link_hash_table_create): New function.
(create_got_section): New function.
(ppc64_elf_create_dynamic_sections): Call create_got_section. Stash
pointers to our dynamic sections in hash table.
(ppc64_elf_copy_indirect_symbol): New function.
(ppc64_elf_check_relocs): Remove DEBUG code. Use short-cuts to
dynamic sections. Localise vars. Modify code for refcounts
starting from zero. Don't allocate here, or force symbols dynamic.
Don't copy all relocs if shared, select ones we need. Add code
to track possible copy relocs for non-shared link.
(ppc64_elf_gc_mark_hook): Update comment.
(ppc64_elf_gc_sweep_hook): Sweep dynrelocs too.
(ppc64_elf_adjust_dynamic_symbol): Remove DEBUG code. Rewrite .plt
code for reference counting garbage collection. Don't create .plt
entries for functions that don't comply with ABI naming convention,
and don't allocate .plt space here. Use short-cuts to dynamic
sections. If possible, keep dynamic relocations instead of using
copy relocs. Remove confused comments.
(ppc_adjust_dynindx): Delete.
(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define.
(allocate_dynrelocs): New function.
(readonly_dynrelocs): New function.
(ppc64_elf_size_dynamic_sections): Rewrite. Allocate local .got
space here, and call allocate_dynrelocs to allocate space for
global .plt, .got and reloc sections. Use short-cuts to dynamic
sections. Call readonly_dynrelocs to determine whether we need
DT_TEXTREL. Don't generate section symbols here, the generic
ELF linker code does it for us.
(ppc64_elf_final_link): Call regular ELF backend linker rather than
gc variety, since we do our own .got handling.
(ppc64_elf_relocate_section): Remove DEBUG code. Make use of
dynamic section short-cuts. Localise vars, and delay setting.
Handle unknown relocs in main switch statement. Replace ugly
complicated tests for unresolvable relocs with a simple direct
scheme using "unresolved_reloc" var. Test ELF_ST_VISIBILITY
before allowing an undefined sym in a shared lib. Do R_*_DS tests
after main switch, when we've set addend. Do non-addend insn
tweaks before main swithc. Ignore input_section->vma when
calculating reloc offsets as it's always zero. Rewrite dynamic
reloc handling. Consolidate R_*_HA handling. Handle more relocs.
(ppc64_elf_finish_dynamic_symbol): Remove DEBUG code. Make use
of dynamic section short-cuts. Reorganise .plt handling code.
Remove confused comments. Take note of ELF_LINK_FORCED_LOCAL.
Move expressions out of swap_reloca_out function calls.
(ppc64_elf_reloc_type_class): New function.
(ppc64_elf_info_to_howto): Move common expression to local var.
(ppc64_elf_finish_dynamic_sections): Remove DEBUG code. Make use
of dynamic section short-cuts. Don't fiddle with section syms
here as the ELF linker does it for us.
(elf_backend_can_refcount): Define.
(bfd_elf64_bfd_link_hash_table_create): Define.
(elf_backend_copy_indirect_symbol): Define.
(elf_backend_reloc_type_class): Define.
(elf_backend_*, bfd_elf64_bfd_* defines): Sort.
