1261
1262         * elflink.h (elf_bfd_final_link): Don't change a DT_INIT or
1263         DT_FINI entry if the appropriate symbol is not in the hash table.
1264
1265         * libelf.h (struct elf_backend_data): Add create_program_headers
1266         and want_hdr_in_seg fields.
1267         * elfxx-target.h (elf_backend_want_hdr_in_seg): Define if not
1268         defined.
1269         (elf_backend_create_program_headers): Likewise.
1270         (elfNN_bed): Initialize create_program_headers and
1271         want_hdr_in_seg.
1272         * elf.c (get_program_header_size): Call create_program_headers
1273         backend routine.
1274         (map_program_segments): Check want_hdr_in_seg backend field.  Call
1275         create_program_headers backend routine.
1276
1277         * elf.c (assign_file_positions_except_relocs): Align non allocated
1278         sections when creating an executable.
1279
1280         * elfcode.h (elf_swap_phdr_in): Make non static.
1281         (elf_swap_phdr_out): Make non static.

1284         (bfd_elf64_swap_phdr_in): Declare.
1285         (bfd_elf64_swap_phdr_out): Declare.
1286
1287         * ecofflink.c (ecoff_collect_shuffle): New static function.
1288         (_bfd_ecoff_get_accumulated_pdr): New function.
1289         (_bfd_ecoff_get_accumulated_sym): New function.
1290         (_bfd_ecoff_get_accumulated_ss): New function.

1297
1298         * libecoff.h (_bfd_ecoff_bfd_print_private_bfd_data): Fix typo.
1299
1300         * elflink.h (elf_link_add_object_symbols): Handle indirect and
1301         warning symbols.  If any section is named .gnu.warning.XXX, treat
1302         the contents as a warning to be issued if the symbol XXX is
1303         referenced.
1304         (elf_link_output_extsym): For an indirect or warning symbol, just
1305         output the symbol it points to.
1306
1307         * linker.c (_bfd_link_hash_newfunc): Don't bother to set bfd_error
1308         if bfd_hash_allocate fails, since it will already be set.

1311         (hash_entry_bfd): New static function.
1312         (_bfd_generic_link_add_one_symbol): Pass new arguments to warning
1313         callback.  Allocate a new warning using the hash table newfunc.
1314         Use bfd_hash_replace to update the entry in the hash table, rather
1315         than assuming we can copy the fields with structure assignment.
1316
1317         * hash.c (bfd_hash_replace): New function.
1318         * bfd-in.h (bfd_hash_replace): Declare.
