* sunos.c: Include bfdlink.h. Add many new functions and definitions for SunOS shared library support. * bfd-in.h (bfd_sunos_record_link_assignment): Declare. (bfd_sunos_size_dynamic_sections): Declare. * bfd-in2.h: Rebuilt. * aoutx.h (struct aout_link_hash_entry): Move to libaout.h. (struct aout_link_hash_table): Likewise. (aout_link_hash_lookup, aout_link_hash_traverse): Likewise. (aout_hash_table): Likewise. (NAME(aout,link_hash_newfunc)): Rename from aout_link_hash_newfunc and make externally visible. (NAME(aout,link_hash_table_init)): New function. (NAME(aout,link_hash_table_create)): Call NAME(aout,link_hash_table_init), not _bfd_link_hash_table_init. (aout_link_add_symbols): Don't fail if no symbols. If it exists, call add_dynamic_symbols backend entry point for dynamic objects. Use add_one_symbol backend entry point if it exists. (NAME(aout,final_link)): Call finish_dynamic_link backend entry point, if it exists. (aout_link_input_bfd): For a dynamic object, call link_dynamic_object backend entry point, if it exists. (aout_link_write_other_symbol): Call write_dynamic_symbol backend entry point, if it exists. (aout_link_input_section): Don't read the relocs if they have already been read. (aout_link_input_section_std): When doing a final link, for a reloc against an external symbol, call check_dynamic_reloc backend entry point, if it exists. (aout_link_input_section_ext): Likewise. * libaout.h: Protect against multiple inclusion. Include bfdlink.h. (struct aout_link_hash_entry): Move in from aoutx.h. (struct aout_link_hash_table): Likewise. (aout_link_hash_lookup, aout_link_hash_traverse): Likewise. (aout_hash_table): Likewise. (struct aout_backend_data): Add fields add_dynamic_symbols, add_one_symbol, link_dynamic_object, write_dynamic_symbol, check_dynamic_reloc, and finish_dynamic_link. (struct aout_section_data_struct): Define new structure. (aout_section_data): Define new accessor macro. (NAME(aout,link_hash_newfunc)): Declare. (NAME(aout,link_hash_table_init)): Declare. * aoutf1.h (sunos4_aout_backend): Initialize new aout_backend_data fields. * aout-target.h (MY(backend_data)): Likewise. * i386aout.c (MY(backend_data)): Likewise. * i386mach3.c (MY(backend_data)): Likewise. * mipsbsd.c (MY(backend_data)): Likewise. * sparclynx.c (sparclynx_aout_backend): Likewise.
