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. + +2001-09-29 Alan Modra <amodra@bigpond.net.au> + * elf-bfd.h (struct elf_link_local_dynamic_entry): Add init_refcount.
