* sunos.c (SPARC_PLT_PIC_WORD0): Define. (SPARC_PLT_PIC_WORD1, SPARC_PLT_PIC_WORD2): Define. (struct sunos_link_hash_entry): Add got_offset and plt_offset fields. (struct sunos_link_hash_table): Add dynamic_sections_created and dynamic_sections_needed fields. (sunos_link_hash_newfunc): Initialize new fields. (sunos_link_hash_table_create): Initialize new fields. (sunos_create_dynamic_sections): New static function, broken out of sunos_add_dynamic_symbols. (sunos_add_dynamic_symbols): Call sunos_create_dynamic_sections. (sunos_add_one_symbol): Call sunos_create_dynamic_sections. (bfd_sunos_size_dynamic_sections): Call sunos_scan_relocs before checking whether we need to set up the dynamic link information. Define __GLOBAL_OFFSET_TABLE if anything referred to it. (sunos_scan_std_relocs): Call sunos_create_dynamic_sections. Use plt_offset field; only put symbol in .plt if it is not defined by a regular object. (sunos_scan_ext_relocs): Likewise. Handle base relative relocs. (sunos_scan_dynamic_symbol): Store dynobj in local variable. (sunos_write_dynamic_symbol): Check plt_offset rather than checking whether symbol is in .plt section. If symbol is defined in a regular object file, use SPARC_PLT_PIC_WORD[012], and don't add a JMP_TBL reloc. (sunos_check_dynamic_reloc): Add contents and relocationp fields. If plt_offset is set, redirect relocation to PLT. If this is a base relative reloc, redirect relocation to GOT. Check dynamic_sections_needed field rather than whether dynobj is set. (sunos_finish_dynamic_link): Check dynamic_sections_needed field rather than whether dynobj is set. Don't die if .need and .rules sections were not created. * aoutx.h (howto_table_ext): Mark PC10, PC22, and JMP_TBL entries PC relative. Mark PC10 complain_overflow_dont. Mark PC22 and JMP_TBL complain_overflow_signed. (NAME(aout,final_link)): If info->shared is set, set DYNAMIC. (aout_link_input_section_std): Call check_dynamic_reloc for all relocs. Pass contents and &relocation. Don't warn about an undefined symbol until check_dynamic_reloc has been called. Don't warn about an undefined symbol for a base relative reloc. (aout_link_input_section_ext): Likewise. For a base relative reloc, always treat r_index as an index into the symbol table. * libaout.h (struct aout_backend_data): Add contents and relocation argument to check_dynamic_reloc entry point. (struct aoutdata): Add local_got_offsets field.
