   2
   3         * bfd-in.h: (bfd_boolean): Add workaround for systems that also
   4         define true and false as enums.
   5         (ALMOST_STDC): Add as alternative to __STDC__.
   6         * bfd-in2.h: Rebuilt.
   7         * syms.c (bfd_print_symbol_vandf): Convert a PTR to FILE*.
   8
   9 Thu Jan  6 14:24:44 1994  David J. Mackenzie  (djm@thepub.cygnus.com)
  10
  11         * aoutx.h (translate_to_native_sym_flags): Catch the case where
  12         there is no output section.
  13
  14 Thu Jan  6 14:37:42 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  15
  16         * nlmcode.h (nlm_object_p): If we can't read the fixed header,
  17         count it as a wrong format error, not a system call error, since
  18         the object file might simply be too small.
  19
  20         * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
  21         BFD64.
  22         * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.
  23         (BFD64_BACKENDS): Add nlm32-alpha.o.  It depends on 64 bit
  24         support, even though it is for an Alpha in 32 bit mode.
  25         * configure.in (nlm32_alpha_vec): Set target64 to true.
  26
  27         * nlm32-gen.c, nlm64-gen.c: Removed.  All nlm targets are
  28         different, so there is no point to providing a generic one.
  29         * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
  30         in the backend accessor macros; that should no longer be possible.
  31         * targets.c (target_vector): Removed nlm32_big_generic_vec,
  32         nlm64_big_generic_vec, nlm64_little_generic_vec.
  33         * configure.in (nlm32_big_generic_vec, nlm32_little_generic_vec,
  34         nlm64_big_generic_vec, nlm64_little_generic_vec): Removed.
  35         * Makefile.in: Rebuilt dependencies, and
  36         (BFD32_BACKENDS): Removed nlm32-gen.o.
  37         (BFD64_BACKENDS): Removed nlm64-gen.o.
  38         (CFILES): Removed nlm32-gen.c and nlm64-gen.c.
  39
  40         * hp300hpux.c (ARCH_SIZE): Define before including aoutx.h.
  41
  42         * linker.c (_bfd_generic_link_add_one_symbol): Add constructor and

  44         * libbfd-in.h (_bfd_generic_link_add_one_symbol): Add constructor
  45         and bitsize arguments to declaration.
  46         * libbfd.h: Rebuilt.

  56         (ecoff_write_object_contents): Put .xdata section in data segment.
  57         Call ecoff_compute_reloc_file_positions.  Don't output relocs or
  58         external symbols if outsymbols is NULL.
  59         (ecoff_bfd_final_link): Completely rewritten.
  60         * libecoff.h: Include bfdlink.h.

  71         * coff-alpha.c (alpha_howto_table): Mark BRADDR as
  72         partial_inplace, and set the src_mask to 0x1fffff.
  73         (alpha_ecoff_get_relocated_section_contents): Remove unused
  74         variable gp_warned.
  75         (alpha_convert_external_reloc): New static function.

  88         against a section symbol, subtract the VMA of the input section.
  89         (aout_link_input_section_ext): Likewise.
  90
  91         * linker.c (default_indirect_link_order): Renamed from
  92         _bfd_generic_indirect_link_order and made static.
  93         (_bfd_generic_final_link): Don't switch on link_order type, just
  94         call _bfd_default_link_order.
  95         (_bfd_default_link_order): Handle bfd_indirect_link_order type.
  96         * genlink.h: Removed declaration of

 105         came from.
 106         (_bfd_generic_link_add_one_symbol): (case BIG): A common symbol
 107         must have a section, so don't bother to create one.
 108

 122         external symbols.
 123
 124         * bfd-in.h, hash.c: Change bfd_hash_allocate argument from size_t

 164
 165         * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
 166         and do the swapping here rather than calling ntohl from the N_*

 221
 222         Extensive changes to move the bulk of the linker into BFD so that

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

 737         addralign of strtab sections to 1.
