1255         * ecofflink.c (ecoff_collect_shuffle): New static function.
1256         (_bfd_ecoff_get_accumulated_pdr): New function.
1257         (_bfd_ecoff_get_accumulated_sym): New function.
1258         (_bfd_ecoff_get_accumulated_ss): New function.
1259         * libbfd-in.h (_bfd_ecoff_get_accumulated_pdr): Declare.
1260         (_bfd_ecoff_get_accumulated_sym): Declare.
1261         (_bfd_ecoff_get_accumulated_ss): Declare.
1262         * libbfd.h: Rebuild.

1265
1266         * libecoff.h (_bfd_ecoff_bfd_print_private_bfd_data): Fix typo.
1267
1268         * elflink.h (elf_link_add_object_symbols): Handle indirect and
1269         warning symbols.  If any section is named .gnu.warning.XXX, treat
1270         the contents as a warning to be issued if the symbol XXX is
1271         referenced.
1272         (elf_link_output_extsym): For an indirect or warning symbol, just
1273         output the symbol it points to.
1274
1275         * linker.c (_bfd_link_hash_newfunc): Don't bother to set bfd_error
1276         if bfd_hash_allocate fails, since it will already be set.
1277         (generic_link_hash_newfunc): Likewise.
1278         (archive_hash_newfunc): Likewise.
1279         (hash_entry_bfd): New static function.
1280         (_bfd_generic_link_add_one_symbol): Pass new arguments to warning
1281         callback.  Allocate a new warning using the hash table newfunc.
1282         Use bfd_hash_replace to update the entry in the hash table, rather
1283         than assuming we can copy the fields with structure assignment.
1284
1285         * hash.c (bfd_hash_replace): New function.
1286         * bfd-in.h (bfd_hash_replace): Declare.
1287         * bfd-in2.h: Rebuild.

1290
1291         * config.bfd: Add mips*vr4300-*-elf* target.
1292         * config/mipsbvr4300.mt: Added.
