bfd/ChangeLog

   1 Fri Jan 21 14:11:16 1994  Sean Fagan (sef@cygnus.com)
   2
   3         * nlmcode.h, liblnm.h, nlm32-alpha.c nlm32-i386.c nlm32-sparc.c:
   4         The sparc (and possibly other?) NLM format requires a different
   5         way to write exports, so add a write_export field to the backend
   6         data (and set it to NULL for everything but the sparc).
   7
   8 Fri Jan 21 14:11:16 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   9
  10         * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,
  11         not (struct external_nlist *) NULL.  info->dynrel is a PTR, not
  12         a struct external_nlist *.

  14 Fri Jan 21 09:29:01 1994  David J. Mackenzie  (djm@thepub.cygnus.com)
  15
  16         * bfd.c: Remove error strings for errors removed below.
  17         * aoutx.h (translate_to_native_sym_flags), bfd-in.h (bfd_ec),
  18         oasys.c (oasys_write_sections): Rename
  19         bfd_error_nonrepresentable_section to nonrepresentable_section.
  20         None of the other bfd error names start with "bfd_error".
  21         Remove errors symbol_not_found and no_relocation_info, which seem
  22         to be unused.
  23         * bfd-in2.h: Regenerated.
  24
  25 Fri Jan 21 01:11:55 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

  39         and relocs.
  40         * aoutx.h (NAME(aout,some_aout_object_p)): If the object is
  41         dynamically linked, set SEC_RELOC for both the .text and .data
  42         sections.
  43         (translate_from_native_sym_flags): Don't set BSF_LOCAL for an
  44         undefined symbol.
  45         (translate_symbol_table): New function, split out of
  46         slurp_symbol_table; set the BSF_DYNAMIC flag appropriately.

  52         out dynamic symbols or relocs against reloc symbols, since they
  53         are already in the .text section and we wouldn't know where to
  54         write them anyhow.
  55         (sunos4_aout_backend): Initialize read_dynamic_symbols and
  56         read_dynamic_relocs fields.
  57         * aout-target.h (MY(backend_data)): Initialize

  61
  62         * hosts/alphaosf.h (uint64e_type, uint64_type, int64_type): Delete
  63         typedefs, since HOST_64_BIT will take care of defining them in
  64         bfd.h.

  75         types.  Reorganized some of the existing ones.
  76         * coff-alpha.c (alpha_howto_table): Construct 64-bit negative one
  77         values in case of compilation on a 32-bit machine.  Fix pcrel
  78         fields of some reloc types.
  79         (alpha_bfd_reloc_type_lookup): Handle more relocation types.
  80
  81         * bfd-in.h (uint64_typeHIGH, uint64_typeLOW): Supply default
  82         definitions when not defined, regardless of whether uint64_type is

  85         already defined.
  86

  97         indirect or warning symbol.  If an indirect symbol is defined,
  98         output the calculated value and don't output the target symbol.
  99
 100 Tue Jan 18 03:54:59 1994  David J. Mackenzie  (djm@thepub.cygnus.com)
 101
 102         * aoutx.h (translate_from_native_sym_flags): Give warning symbols
 103         an (unused) nonzero section value, needed for check below.

 115         (NAME(bfd_elf,write_object_contents)): Don't try to write out a
 116         BFD with the DYNAMIC flag set, since we don't generate the program
 117         header table correctly.
 118
 119 Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

 122         of the function to avoid storage leak.
 123
 124 Thu Jan 13 23:07:32 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

 166
 167         * ecofflink.c: Extensive changes to compress and merge debugging
 168         information, and to write some of out directly rather than saving
 169         it in memory.  Several new functions and structures, and new
 170         arguments to existing functions.
 171         * ecoff.c (ecoff_compute_reloc_file_positions): Compute

 184         (mips_elf_final_link): Adjust for changes in bfd_ecoff functions.
 185         Preserve .text, .data and .bss even if they are empty.  Save
 186         pointer to unswapped external symbol rather than copying it.
 187         Don't free up the external symbols.
 188         * libelf.h (elf_symbol_type): Change mips_extr to PTR.

 200         this position it just causes errors, not suppresses echoes.
 201
 202 Mon Jan 10 09:06:21 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 203

 238
 239         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
 240         count it as a wrong format error, not a system call error, since

 249
 250         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are

 252         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
 253         in the backend accessor macros; that should no longer be possible.

 257         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
 258         * Makefile.in: Rebuilt dependencies, and
 259         (BFD32_BACKENDS): Removed nlm32-gen.o.
 260         (BFD64_BACKENDS): Removed nlm64-gen.o.

 273         (ecoff_sec_to_styp_flags): Set flags for .pdata and .xdata.
 274         (ecoff_slurp_symbolic_header): New function.

 278         Check errors better.
 279         (ecoff_write_object_contents): Put .xdata section in data segment.
 280         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
 281         external symbols if outsymbols is NULL.
 282         (ecoff_bfd_final_link): Completely rewritten.
 283         * libecoff.h: Include bfdlink.h.

 311         against a section symbol, subtract the VMA of the input section.
 312         (aout_link_input_section_ext): Likewise.
 313

1266
1267         * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
1268         Handle symbol number of zero.
1269
1270         * reloc.c (enum bfd_reloc_code_real): Added
1271         BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
1272         BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
1273         * bfd-in2.h: Rebuilt.
1274         * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
1275         BFD_RELOC_MIPS_LITERAL.
1276         * elf32-mips.c (mips_reloc_map): Handle new relocs.
1277         (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
1278         checks slightly.
1279
1280         * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
1281         MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
1282         (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
1283         MY_bfd_seclet_link): Define.
1284         (MY_bfd_reloc_type_lookup): Rename from
1285         MY_reloc_howto_type_lookup.
1286         (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
1287         (MY(vec)): Use JUMP_TABLE rather than listing functions.
1288         * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
1289         MY_canonicalize_reloc, MY_write_object_contents): Don't define in
1290         terms of MY, because that causes a recusive invocation of CAT when
1291         expanded within JUMP_TABLE, and ANSI compilers don't expand
1292         recursive macros.
1293         * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
1294         MY_reloc_howto_type_lookup, and don't define in terms of MY.
1295         (MY_canonicalize_reloc): Don't define in terms of MY.
1296         (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
1297         than listing functions.
