   2
   3         * config.bfd: Use ELF, not COFF for m88*-*-dgux*.
   4         Combine m88k-*-* and m88110-*-* cases into m88*-*-*.
   5
   6 Mon Jan 10 20:46:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   7
   8         * Makefile.in (install): Remove "@" which follows a backslash.  In
   9         this position it just causes errors, not suppresses echoes.
  10
  11 Mon Jan 10 09:06:21 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

  23         end of data if they are not contiguous.
  24
  25         * aoutf1.h (sunos4_aout_backend): Comment the fields' meanings.
  26
  27 Fri Jan  7 15:40:16 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  28
  29         * ecoff.c (ecoff_mkobject_hook): Don't set SEC_SHARED_LIBRARY flag
  30         for .reginfo section here.
  31         (ecoff_new_section_hook): Set it here instead.
  32

  34
  35         * bfd-in.h: (bfd_boolean): Add workaround for systems that also
  36         define true and false as enums.
  37         (ALMOST_STDC): Add as alternative to __STDC__.
  38         * bfd-in2.h: Rebuilt.
  39         * syms.c (bfd_print_symbol_vandf): Convert a PTR to FILE*.
  40
  41 Thu Jan  6 14:24:44 1994  David J. Mackenzie  (djm@thepub.cygnus.com)

  44         there is no output section.
  45
  46 Thu Jan  6 14:37:42 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  47
  48         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
  49         count it as a wrong format error, not a system call error, since
  50         the object file might simply be too small.
  51
  52         * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
  53         BFD64.

  56         support, even though it is for an Alpha in 32 bit mode.
  57         * configure.in (nlm32_alpha_vec): Set target64 to true.
  58
  59         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are
  60         different, so there is no point to providing a generic one.
  61         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
  62         in the backend accessor macros; that should no longer be possible.
  63         * targets.c (target_vector): Removed nlm32_big_generic_vec,
  64         nlm64_big_generic_vec, nlm64_little_generic_vec.

  66         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
  67         * Makefile.in: Rebuilt dependencies, and
  68         (BFD32_BACKENDS): Removed nlm32-gen.o.
  69         (BFD64_BACKENDS): Removed nlm64-gen.o.

  77         and bitsize arguments to declaration.

  89         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
  90         external symbols if outsymbols is NULL.
  91         (ecoff_bfd_final_link): Completely rewritten.
  92         * libecoff.h: Include bfdlink.h.

 103         * coff-alpha.c (alpha_howto_table): Mark BRADDR as
 104         partial_inplace, and set the src_mask to 0x1fffff.
 105         (alpha_ecoff_get_relocated_section_contents): Remove unused
 106         variable gp_warned.

 120         against a section symbol, subtract the VMA of the input section.
 121         (aout_link_input_section_ext): Likewise.
 122
 123         * linker.c (default_indirect_link_order): Renamed from
 124         _bfd_generic_indirect_link_order and made static.
 125         (_bfd_generic_final_link): Don't switch on link_order type, just
 126         call _bfd_default_link_order.
 127         (_bfd_default_link_order): Handle bfd_indirect_link_order type.
 128         * genlink.h: Removed declaration of

 138         (_bfd_generic_link_add_one_symbol): (case BIG): A common symbol
 139         must have a section, so don't bother to create one.
 140
 141 Mon Jan  3 15:32:16 1994  David J. Mackenzie  (djm@thepub.cygnus.com)

 154         external symbols.
 155
 156         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 253
 254         Extensive changes to move the bulk of the linker into BFD so that
 255         more efficient backend code can be written for specific object

 282         * libbfd.c (bfd_seek): Comment out fseek assertion.  It's worked

 289         callers.
 290         (_bfd_final_link_relocate, _bfd_relocate_contents): New functions.

 982         <mellon@pepper.ncd.com>.
 983
 984         * bout.c (b_out_reloc_type_lookup): Return type should point to
