  43
  44         * ecofflink.c: Extensive changes to compress and merge debugging
  45         information, and to write some of out directly rather than saving
  46         it in memory.  Several new functions and structures, and new
  47         arguments to existing functions.
  48         * ecoff.c (ecoff_compute_reloc_file_positions): Compute

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

  77         this position it just causes errors, not suppresses echoes.
  78
  79 Mon Jan 10 09:06:21 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

 115
 116         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
 117         count it as a wrong format error, not a system call error, since
 118         the object file might simply be too small.

 126
 127         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are
 128         different, so there is no point to providing a generic one.
 129         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
 130         in the backend accessor macros; that should no longer be possible.
 131         * targets.c (target_vector): Removed nlm32_big_generic_vec,
 132         nlm64_big_generic_vec, nlm64_little_generic_vec.

 134         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
 135         * Makefile.in: Rebuilt dependencies, and
 136         (BFD32_BACKENDS): Removed nlm32-gen.o.
 137         (BFD64_BACKENDS): Removed nlm64-gen.o.

 145         and bitsize arguments to declaration.

 156         (ecoff_write_object_contents): Put .xdata section in data segment.
 157         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
 158         external symbols if outsymbols is NULL.
 159         (ecoff_bfd_final_link): Completely rewritten.
 160         * libecoff.h: Include bfdlink.h.

 171         * coff-alpha.c (alpha_howto_table): Mark BRADDR as
 172         partial_inplace, and set the src_mask to 0x1fffff.
 173         (alpha_ecoff_get_relocated_section_contents): Remove unused
 174         variable gp_warned.

 188         against a section symbol, subtract the VMA of the input section.
 189         (aout_link_input_section_ext): Likewise.
 190
 191         * linker.c (default_indirect_link_order): Renamed from
 192         _bfd_generic_indirect_link_order and made static.
 193         (_bfd_generic_final_link): Don't switch on link_order type, just
 194         call _bfd_default_link_order.

 223
 224         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 264
 265         * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
 266         and do the swapping here rather than calling ntohl from the N_*

 837         addralign of strtab sections to 1.
