(mips_elf_link_hash_newfunc): Update after the changes to mips_elf_link_hash_entry. (mips_elf_check_mips16_stubs): Replace the DATA parameter with an INFO parameter. Don't look through warnings symbols here; do it in mips_elf_check_symbols instead. (mips_elf_create_stub_symbol): New function. (mips_elf_la25_stub_hash, mips_elf_la25_stub_eq): New functions. (_bfd_mips_elf_init_stubs, mips_elf_local_pic_function_p): Likewise. (mips_elf_add_la25_intro, mips_elf_add_la25_trampoline): Likewise. (mips_elf_add_la25_stub, mips_elf_check_symbols): New functions. (mips_elf_gotplt_index): Check for VxWorks. (mips_elf_output_dynamic_relocation): Take the relocation index as an extra parameter. Do not increment reloc_count here. (mips_elf_initialize_tls_slots): Update the calls to mips_elf_output_dynamic_relocation accordingly. (mips_elf_multi_got): Use htab->reserved_gotno instead of MIPS_RESERVED_GOTNO. (mips_elf_create_got_section): Don't allocate reserved GOT entries here. Unconditionally create .got.plt, but don't set its alignment here. (mips_elf_relocation_needs_la25_stub): New function. (mips_elf_calculate_relocation): Redirect branches and jumps to a non-PIC stub if one exists. Check !h->has_static_relocs instead of !htab->is_vxworks when deciding whether to create dynamic relocations for R_MIPS_32, R_MIPS_REL32 and R_MIPS_64. (_bfd_mips_elf_create_dynamic_sections): Unconditionally call _bfd_elf_create_dynamic_sections. Unconditionally set up htab->splt and htab->sdynbss. Set htab->srelplt to ".rel.plt" if !htab->is_vxworks. Add non-VxWorks values of htab->plt_header_size and htab->plt_entry_size. (_bfd_mips_elf_check_relocs): Set pointer_equality_needed for non-branch static relocations. Set has_nonpic_branches when an la25 stub might be required. Set can_make_dynamic_p to TRUE if R_MIPS_32, R_MIPS_REL32 and R_MIPS_64 relocations can be made dynamic, rather than duplicating the condition. Do not make them dynamic for read-only sections in non-PIC executable objects. Do not protect this code with dynobj == NULL || htab->sgot == NULL; handle each group of cases separately. Add a default case that sets has_static_relocs for non-GOT relocations that cannot be made dynamic. Don't set is_relocation_target and is_branch_target. Reject non-PIC static relocations in shared objects. (_bfd_mips_vxworks_adjust_dynamic_symbol): Fold into... (_bfd_mips_elf_adjust_dynamic_symbol): ...here, using htab->use_plts_and_copy_relocs instead of htab->is_vxworks to select PLT and copy-reloc handling. Set the alignment of .plt and .got.plt when allocating the first entry. Generalize code to handle REL as well as RELA sections and 64-bit as well as 32-bit GOT entries. Complain if we find a static-only reloc against an externally-defined symbol and if we cannot create dynamic relocations for it. Allocate copy relocs using mips_elf_allocate_dynamic_relocations on non-VxWorks targets. Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs. Skip reserved .got.plt entries. (_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols instead of mips_elf_check_mips16_stubs to process each symbol. Do the traversal for relocatable objects too. (mips_elf_lay_out_got): Use htab->reserved_gotno instead of MIPS_RESERVED_GOTNO. (_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the PLT. Allocate a nop at the end of the PLT. Allocate DT_MIPS_PLTGOT. (mips_elf_create_la25_stub_info): New function. (_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries and copy relocs where necessary. Check pointer_equality_needed. (mips_finish_exec_plt): New function. (_bfd_mips_elf_finish_dynamic_sections): Always set DT_PLTGOT to the beginning of htab->sgot. Use htab->reserved_gotno instead of MIPS_RESERVED_GOTNO. Assert htab->use_plts_and_copy_relocs instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL. Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets. Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set DT_MIPS_PLTGOT. (_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs from the indirect symbol to the direct symbol. Also copy has_nonpic_branches for indirect symbols. (_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and DT_MIPS_RWPLT. (_bfd_mips_elf_link_hash_table_create): Initialize the new mips_elf_link_hash_table fields. (_bfd_mips_vxworks_link_hash_table_create): Set use_plts_and_copy_relocs to TRUE. Use TRUE rather than 1 when setting is_vxworks. (_bfd_mips_elf_use_plts_and_copy_relocs): New function. (_bfd_mips_elf_final_link): Call mips_elf_create_la25_stub for each la25_stub. (_bfd_mips_elf_merge_private_bfd_data): Treat dynamic objects as PIC. Generalize message about linking PIC and non-PIC.
