 281         * coff-a29k.c (a29k_reloc): For R_IREL, don't left shift
 282         signed_value before sign extending it.  Don't subtract out

 284         generating.
 285
 286         * elfcode.h (elf_fake_sections): Accept .sbss as the name for a
 287         SHT_NOBITS sections.

 293         a SHT_NOBITS section to only do it for the last such consecutive
 294         section, and to really force page alignment.

 300
 301         * config/i386-lynx.mt (TDEFINES): FPRINTF_ALREADY_DECLARED should

 640         * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
 641         in last change.  Always rebuild symbol extension section the first
 642         time though if output sections exist (fixes ld -r problems).

 649
 650         * libbfd-in.h (artdata): Use long, not time_t for portability, at
 651           least to HPUX.  File below is a derived file.

 663
 664         * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
 665         Handle symbol number of zero.
 666
 667         * reloc.c (enum bfd_reloc_code_real): Added
 668         BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
 669         BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
 670         * bfd-in2.h: Rebuilt.
 671         * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
 672         BFD_RELOC_MIPS_LITERAL.
 673         * elf32-mips.c (mips_reloc_map): Handle new relocs.
 674         (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
 675         checks slightly.
 676
 677         * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
 678         MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
 679         (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
 680         MY_bfd_seclet_link): Define.
 681         (MY_bfd_reloc_type_lookup): Rename from
 682         MY_reloc_howto_type_lookup.
 683         (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
 684         (MY(vec)): Use JUMP_TABLE rather than listing functions.
 685         * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
 686         MY_canonicalize_reloc, MY_write_object_contents): Don't define in
 687         terms of MY, because that causes a recusive invocation of CAT when
 688         expanded within JUMP_TABLE, and ANSI compilers don't expand
 689         recursive macros.
 690         * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
 691         MY_reloc_howto_type_lookup, and don't define in terms of MY.
 692         (MY_canonicalize_reloc): Don't define in terms of MY.
 693         (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
 694         than listing functions.
