1273
1274         * elflink.h (elf_bfd_final_link): Don't change a DT_INIT or
1275         DT_FINI entry if the appropriate symbol is not in the hash table.
1276
1277         * libelf.h (struct elf_backend_data): Add create_program_headers
1278         and want_hdr_in_seg fields.
1279         * elfxx-target.h (elf_backend_want_hdr_in_seg): Define if not
1280         defined.
1281         (elf_backend_create_program_headers): Likewise.
1282         (elfNN_bed): Initialize create_program_headers and
1283         want_hdr_in_seg.
1284         * elf.c (get_program_header_size): Call create_program_headers
1285         backend routine.
1286         (map_program_segments): Check want_hdr_in_seg backend field.  Call
1287         create_program_headers backend routine.
1288
1289         * elf.c (assign_file_positions_except_relocs): Align non allocated
1290         sections when creating an executable.
1291
1292         * elfcode.h (elf_swap_phdr_in): Make non static.
1293         (elf_swap_phdr_out): Make non static.

1297         (bfd_elf64_swap_phdr_out): Declare.
1298
1299         * ecofflink.c (ecoff_collect_shuffle): New static function.
1300         (_bfd_ecoff_get_accumulated_pdr): New function.
1301         (_bfd_ecoff_get_accumulated_sym): New function.

1309
1310         * libecoff.h (_bfd_ecoff_bfd_print_private_bfd_data): Fix typo.
1311
1312         * elflink.h (elf_link_add_object_symbols): Handle indirect and
1313         warning symbols.  If any section is named .gnu.warning.XXX, treat
1314         the contents as a warning to be issued if the symbol XXX is
1315         referenced.
1316         (elf_link_output_extsym): For an indirect or warning symbol, just
1317         output the symbol it points to.
1318
1319         * linker.c (_bfd_link_hash_newfunc): Don't bother to set bfd_error
1320         if bfd_hash_allocate fails, since it will already be set.

1322         (archive_hash_newfunc): Likewise.
1323         (hash_entry_bfd): New static function.
1324         (_bfd_generic_link_add_one_symbol): Pass new arguments to warning
1325         callback.  Allocate a new warning using the hash table newfunc.
1326         Use bfd_hash_replace to update the entry in the hash table, rather
1327         than assuming we can copy the fields with structure assignment.
1328
1329         * hash.c (bfd_hash_replace): New function.
1330         * bfd-in.h (bfd_hash_replace): Declare.
