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

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

  73         this position it just causes errors, not suppresses echoes.
  74
  75 Mon Jan 10 09:06:21 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

 111
 112         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
 113         count it as a wrong format error, not a system call error, since
 114         the object file might simply be too small.
 115
 116         * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef

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

 130         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
 131         * Makefile.in: Rebuilt dependencies, and
 132         (BFD32_BACKENDS): Removed nlm32-gen.o.
 133         (BFD64_BACKENDS): Removed nlm64-gen.o.
 134         (CFILES): Removed nlm32-gen.c and nlm64-gen.c.
 135
 136         * hp300hpux.c (ARCH_SIZE): Define before including aoutx.h.
 137
 138         * linker.c (_bfd_generic_link_add_one_symbol): Add constructor and

 141         and bitsize arguments to declaration.
 142         * libbfd.h: Rebuilt.
 143

 151         Check errors better.
 152         (ecoff_write_object_contents): Put .xdata section in data segment.
 153         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
 154         external symbols if outsymbols is NULL.
 155         (ecoff_bfd_final_link): Completely rewritten.
 156         * libecoff.h: Include bfdlink.h.
 157         (struct ecoff_backend_data): Add relocate_section field.
 158         (ecoff_data_type): Add sym_hashes and symndx_to_section fields.
 159         (struct ecoff_link_hash_entry): Define.
 160         (struct ecoff_link_hash_table): Define.

 167         * coff-alpha.c (alpha_howto_table): Mark BRADDR as
 168         partial_inplace, and set the src_mask to 0x1fffff.
 169         (alpha_ecoff_get_relocated_section_contents): Remove unused
 170         variable gp_warned.
 171         (alpha_convert_external_reloc): New static function.

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

 219
 220         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 260
 261         * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
 262         and do the swapping here rather than calling ntohl from the N_*

 298         * libaout.h (struct internal_exec): Removed unnecessary
 299         declaration.

 833         addralign of strtab sections to 1.
