  36
  37         * ecofflink.c: Extensive changes to compress and merge debugging
  38         information, and to write some of out directly rather than saving
  39         it in memory.  Several new functions and structures, and new
  40         arguments to existing functions.
  41         * ecoff.c (ecoff_compute_reloc_file_positions): Compute
  42         sym_filepos as well.

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

  69         * Makefile.in (install): Remove "@" which follows a backslash.  In
  70         this position it just causes errors, not suppresses echoes.
  71
  72 Mon Jan 10 09:06:21 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  73
  74         * som.c (hppa_som_gen_reloc_type): Fix handling of LT and RT

 108
 109         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
 110         count it as a wrong format error, not a system call error, since
 111         the object file might simply be too small.
 112
 113         * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
 114         BFD64.

 119
 120         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are
 121         different, so there is no point to providing a generic one.
 122         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
 123         in the backend accessor macros; that should no longer be possible.
 124         * targets.c (target_vector): Removed nlm32_big_generic_vec,
 125         nlm64_big_generic_vec, nlm64_little_generic_vec.

 127         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
 128         * Makefile.in: Rebuilt dependencies, and
 129         (BFD32_BACKENDS): Removed nlm32-gen.o.
 130         (BFD64_BACKENDS): Removed nlm64-gen.o.

 138         and bitsize arguments to declaration.

 148         Check errors better.
 149         (ecoff_write_object_contents): Put .xdata section in data segment.
 150         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
 151         external symbols if outsymbols is NULL.
 152         (ecoff_bfd_final_link): Completely rewritten.
 153         * libecoff.h: Include bfdlink.h.

 155         (ecoff_data_type): Add sym_hashes and symndx_to_section fields.
 156         (struct ecoff_link_hash_entry): Define.
 157         (struct ecoff_link_hash_table): Define.

 164         * coff-alpha.c (alpha_howto_table): Mark BRADDR as
 165         partial_inplace, and set the src_mask to 0x1fffff.
 166         (alpha_ecoff_get_relocated_section_contents): Remove unused
 167         variable gp_warned.

 181         against a section symbol, subtract the VMA of the input section.
 182         (aout_link_input_section_ext): Likewise.
 183
 184         * linker.c (default_indirect_link_order): Renamed from
 185         _bfd_generic_indirect_link_order and made static.
 186         (_bfd_generic_final_link): Don't switch on link_order type, just
 187         call _bfd_default_link_order.
 188         (_bfd_default_link_order): Handle bfd_indirect_link_order type.
 189         * genlink.h: Removed declaration of

 215         external symbols.
 216
 217         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 257
 258         * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
 259         and do the swapping here rather than calling ntohl from the N_*

 261         the existence to ntohl, etc.
 262

 295         * libaout.h (struct internal_exec): Removed unnecessary
 296         declaration.

 647         optional_prefix_size.
 648         (nlm_write_object_contents): Account for optional_prefix_size.
 649         Removed useless variable write_reloc_func.  Changed declaration

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

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

 830         addralign of strtab sections to 1.
