   5
   6         * aoutf1.h (sunos4_aout_backend): Comment the fields' meanings.

  15
  16         * bfd-in.h: (bfd_boolean): Add workaround for systems that also
  17         define true and false as enums.
  18         (ALMOST_STDC): Add as alternative to __STDC__.
  19         * bfd-in2.h: Rebuilt.
  20         * syms.c (bfd_print_symbol_vandf): Convert a PTR to FILE*.
  21
  22 Thu Jan  6 14:24:44 1994  David J. Mackenzie  (djm@thepub.cygnus.com)
  23
  24         * aoutx.h (translate_to_native_sym_flags): Catch the case where
  25         there is no output section.
  26
  27 Thu Jan  6 14:37:42 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  28
  29         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
  30         count it as a wrong format error, not a system call error, since
  31         the object file might simply be too small.
  32
  33         * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
  34         BFD64.

  39
  40         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are
  41         different, so there is no point to providing a generic one.
  42         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
  43         in the backend accessor macros; that should no longer be possible.
  44         * targets.c (target_vector): Removed nlm32_big_generic_vec,
  45         nlm64_big_generic_vec, nlm64_little_generic_vec.

  47         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
  48         * Makefile.in: Rebuilt dependencies, and
  49         (BFD32_BACKENDS): Removed nlm32-gen.o.
  50         (BFD64_BACKENDS): Removed nlm64-gen.o.
  51         (CFILES): Removed nlm32-gen.c and nlm64-gen.c.
  52
  53         * hp300hpux.c (ARCH_SIZE): Define before including aoutx.h.

  58         and bitsize arguments to declaration.

  72         (ecoff_bfd_final_link): Completely rewritten.
  73         * libecoff.h: Include bfdlink.h.

  87         variable gp_warned.

 101         against a section symbol, subtract the VMA of the input section.
 102         (aout_link_input_section_ext): Likewise.
 103
 104         * linker.c (default_indirect_link_order): Renamed from
 105         _bfd_generic_indirect_link_order and made static.
 106         (_bfd_generic_final_link): Don't switch on link_order type, just
 107         call _bfd_default_link_order.

 120         must have a section, so don't bother to create one.
 121

 136
 137         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 234
 235         Extensive changes to move the bulk of the linker into BFD so that

 621         because there is a start address.

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

 750         addralign of strtab sections to 1.
