   2
   3         * som.c (R_DLT_REL, R_AUX_UNWIND, R_SEC_STMT): Add protected
   4         definitions for old versions of HPUX which fail to define them.
   5         (som_hppa_howto_talbe): Add R_DLT_REL, R_AUX_UNWIND, and R_SEC_STMT
   6         now that they're safe.  Delete bogus R_STATEMENT relocations.
   7
   8         * som.c (som_hppa_howto_table): Add missing R_END_TRY.  Delete
   9         extra R_DATA_OVERRIDE.
  10         (hppa_som_gen_reloc_type): Generate a relocation for the rounding
  11         mode selector if needed.
  12         (som_write_fixups): Handle requests for a change in the default
  13         rounding mode.  Rounding modes do not consume input bytes, but
  14         are just markers much like R_ENTRY and R_EXIT.

  22         hppa_elf_reloc):  Avoid useless call to bfd_put_32 () in the
  23         case of no code reordering due to an LDO instruction in the
  24         delay slot of the branch.  Make sure to relocate the correct
  25         instruction.  Do not perform instruction reordering for millicode
  26         calls.
  27         (hppa_elf_build_arg_reloc_stub):  Change the relocation type
  28         to R_HPPA_STUB_CALL_17 when special processing might be needed.
  29         (hppa_elf_build_long_branch_stub): Prevent code reordering on
  30         a call from a linker stub to another linker stub and for millicode
  31         calls.  Do not trash the return register for calls from one linker
  32         stub to a second linker stub.
  33
  34         * elf32-hppa.c: (elf_hppa_howto_table):  PLABEL and DLT
  35         relocations are not pc-relative.
  36
  37         * hppa_stubs.h: (BLE_N_XXX_0_31):  New instruction used in
  38         linker stub code.
  39         (COPY_2_31):  Likewise.

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

 259         generating.
 260
 261         * elfcode.h (elf_fake_sections): Accept .sbss as the name for a
 262         SHT_NOBITS sections.

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

 272
 273         * coffcode.h (coff_slurp_symbol_table): Print more verbose message

 275
 276         * config/i386-lynx.mt (TDEFINES): FPRINTF_ALREADY_DECLARED should

 279         * config/m68k-lynx.mt, config/sparc-lynx.mt: Ditto.
 280

 638
 639         * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
 640         Handle symbol number of zero.
 641
 642         * reloc.c (enum bfd_reloc_code_real): Added
 643         BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
 644         BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
 645         * bfd-in2.h: Rebuilt.
 646         * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
 647         BFD_RELOC_MIPS_LITERAL.
 648         * elf32-mips.c (mips_reloc_map): Handle new relocs.
 649         (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
 650         checks slightly.
 651
 652         * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
 653         MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
 654         (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
 655         MY_bfd_seclet_link): Define.
 656         (MY_bfd_reloc_type_lookup): Rename from
 657         MY_reloc_howto_type_lookup.
 658         (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
 659         (MY(vec)): Use JUMP_TABLE rather than listing functions.
 660         * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
 661         MY_canonicalize_reloc, MY_write_object_contents): Don't define in
 662         terms of MY, because that causes a recusive invocation of CAT when
 663         expanded within JUMP_TABLE, and ANSI compilers don't expand
 664         recursive macros.
 665         * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
 666         MY_reloc_howto_type_lookup, and don't define in terms of MY.
 667         (MY_canonicalize_reloc): Don't define in terms of MY.
 668         (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
 669         than listing functions.
