   7
   8         * ecofflink.c: Extensive changes to compress and merge debugging
   9         information, and to write some of out directly rather than saving
  10         it in memory.  Several new functions and structures, and new
  11         arguments to existing functions.
  12         * ecoff.c (ecoff_compute_reloc_file_positions): Compute
  13         sym_filepos as well.
  14         (ecoff_get_extr): Use ifdmap instead of ifdbase.
  15         (ecoff_write_object_contents): Don't compute sym_filepos here.
  16         Only output symbols if outsymbols is not NULL.
  17         (ecoff_bfd_final_link): Adjust for changes in ecoff_debug_info and
  18         bfd_ecoff_debug functions.  Write out debugging information here.
  19         (ecoff_final_link_debug_accumulate): Adjust for changes in
  20         bfd_ecoff_debug functions.
  21         (ecoff_link_write_external): Use ifdmap rather than ifdbase.
  22         * elf32-mips.c (mips_elf_read_ecoff_info): Read external symbols
  23         first, to put them in the first memory buffer.  Clear fdr field.
  24         (mips_elf_get_extr): Use pointer to unswapped external symbol.
  25         (mips_elf_final_link): Adjust for changes in bfd_ecoff functions.
  26         Preserve .text, .data and .bss even if they are empty.  Save
  27         pointer to unswapped external symbol rather than copying it.
  28         Don't free up the external symbols.
  29         * libelf.h (elf_symbol_type): Change mips_extr to PTR.
  30         * bfd-in.h (bfd_ecoff_debug_init, bfd_ecoff_debug_free): Declare.

  39
  40         * Makefile.in (install): Remove "@" which follows a backslash.  In
  41         this position it just causes errors, not suppresses echoes.
  42
  43 Mon Jan 10 09:06:21 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  44
  45         * som.c (hppa_som_gen_reloc_type): Fix handling of LT and RT

  58

  77
  78 Thu Jan  6 14:37:42 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  79
  80         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
  81         count it as a wrong format error, not a system call error, since
  82         the object file might simply be too small.
  83
  84         * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef

  87         (BFD64_BACKENDS): Add nlm32-alpha.o.  It depends on 64 bit

  90
  91         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are
  92         different, so there is no point to providing a generic one.
  93         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
  94         in the backend accessor macros; that should no longer be possible.
  95         * targets.c (target_vector): Removed nlm32_big_generic_vec,
  96         nlm64_big_generic_vec, nlm64_little_generic_vec.

  98         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
  99         * Makefile.in: Rebuilt dependencies, and
 100         (BFD32_BACKENDS): Removed nlm32-gen.o.
 101         (BFD64_BACKENDS): Removed nlm64-gen.o.
 102         (CFILES): Removed nlm32-gen.c and nlm64-gen.c.
 103
 104         * hp300hpux.c (ARCH_SIZE): Define before including aoutx.h.

 109         and bitsize arguments to declaration.
 110         * libbfd.h: Rebuilt.

 119         Check errors better.
 120         (ecoff_write_object_contents): Put .xdata section in data segment.
 121         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
 122         external symbols if outsymbols is NULL.
 123         (ecoff_bfd_final_link): Completely rewritten.
 124         * libecoff.h: Include bfdlink.h.

 135         * coff-alpha.c (alpha_howto_table): Mark BRADDR as
 136         partial_inplace, and set the src_mask to 0x1fffff.
 137         (alpha_ecoff_get_relocated_section_contents): Remove unused
 138         variable gp_warned.

 152         against a section symbol, subtract the VMA of the input section.
 153         (aout_link_input_section_ext): Likewise.
 154
 155         * linker.c (default_indirect_link_order): Renamed from
 156         _bfd_generic_indirect_link_order and made static.
 157         (_bfd_generic_final_link): Don't switch on link_order type, just
 158         call _bfd_default_link_order.
 159         (_bfd_default_link_order): Handle bfd_indirect_link_order type.
 160         * genlink.h: Removed declaration of

 169         came from.
 170         (_bfd_generic_link_add_one_symbol): (case BIG): A common symbol
 171         must have a section, so don't bother to create one.
 172
 173 Mon Jan  3 15:32:16 1994  David J. Mackenzie  (djm@thepub.cygnus.com)
 174

 186         external symbols.
 187
 188         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 228
 229         * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
 230         and do the swapping here rather than calling ntohl from the N_*
 231         macros.  This cleans up assumptions about the size of a host long,
 232         the existence to ntohl, etc.
 233

 285
 286         Extensive changes to move the bulk of the linker into BFD so that
 287         more efficient backend code can be written for specific object
 288         files.  Only existing efficient backend is a.out.

 619         (nlm_write_object_contents): Account for optional_prefix_size.
 620         Removed useless variable write_reloc_func.  Changed declaration

 622         exists.  Removed unused variables len and temp.  Call
 623         get_public_offset_func if it exists rather than setting NLM_HIBIT.

 638
 639         * coff-alpha.c (alpha_ecoff_get_relocated_section_contents):

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

 801         addralign of strtab sections to 1.
