2219 of the .plt section.
2220 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
2221 seen, skip most of this function, and force the size of the

2223 an empty .plt section.
2224 (elf32_sparc_relocate_section): For a GOT reloc against a global
2225 symbol when no dynamic object was seen, initialize the contents of
2226 the .got section. For a GOT reloc against a local symbol, only

5779 _bfd_generic_link_add_symbols but also collect constructors and
5780 destructors by name as collect2 does.

5799 extended name table.
5801 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5803 Support for link_order types which generate relocs in order to
5804 support -Ur in the linker.
5805 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5806 from call to _bfd_generic_link_add_one_symbol.
5807 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5808 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5809 instead of bitsize to add_to_set call back.
5810 (_bfd_generic_final_link): Account for link_order relocs when
5811 allocating space for relocations. Handle them in link_order loop.
5812 (_bfd_generic_reloc_link_order): New function.

5830 allocating space for relocations. Handle them in link_order loop.
5831 (ecoff_link_write_external): Set the storage class of a defined
5832 linker created symbol based on the section it is in. Correct
5833 bfd_link_hash_weak case to use .sc rather than .st.
5834 (ecoff_reloc_link_order): New function.
5835 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

5846 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5848 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5850 * som.c (bfd_section_from_som_symbol): Only to do the value
5851 comparison for function symbols within executables.
5853 * som.c (bfd_section_from_som_symbol): Renamed from
5854 som_section_from_subspace_index. Pass in a native SOM symbol.
5855 For executables, iterate through the sections to find out
5856 which contains the symbol's address rather than using the
5857 symbol_info field. (symbol_info has a different meaning for
5858 dynamicly linked executables.)
5860 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5863 * som.c (som_begin_writing): Fix braino (one call to align
5864 space/subspace data was done unconditionally rather than
5865 just for executables.)
5867 * som.c (som_begin_writing): Align text in all executables to
5868 make HPUX kernel happy. Fixes strip/objcopy for shared
5871 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5873 * som.c (som_begin_writing): Account for alignment needs of
5874 subspaces too when writing executables. Never request a negative
5875 bss size. Fixes some problems with demand paged executables,
5876 still having problems with pure executables and shared executables.
5878 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5880 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5881 bfd_zalloc for rawptr, because later on we may call free, not
5884 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5885 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5886 * cisco-core.c: New file.
5887 * Makefile.in: Change accordingly.
5888 * configure.in: Recognize cisco_core_vec.
5889 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5890 * targets.c: Add cisco_core_vec.

5893 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5895 * som.h (som_copyable_section_data_struct): New structure
5896 containing all the private section information which needs
5897 to be copied from input section to output section during
5899 (som_section_data_struct): Remove several fields now in
5900 som_copyable_section_data_struct. Make the space and
5901 subspace dictionaries be pointers (to save space when
5902 only reading objects).
5904 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5905 some references changed. Allocate a copyable data stucture if
5906 none exists. Store info into the copyable data structure.
5907 (bfd_som_set_subsection_attributes): Likewise.
5908 (som_is_space, som_is_subspace, som_is_container): New functions.
5909 Use these instead of directly accessing private data.
5910 (som_prep_headers): Allocate space and subspace headers here.
5911 Fill in some fields in the space/subspace headers from the
5913 (som_bfd_copy_private_section_data): Only copy the stuff
5914 that we really need to make objcopy and strip work. Allocate
5915 the copy_data structure for the output bfd before copying.
5917 * som.h (struct som_exec_data): New structure to hold exec
5918 info that must be preserved when running objcopy/strip.
5919 (struct somdata): Add new "exec_data" field and accessor
5920 macro. Add some comments on how the various fields are used.
5921 (som_section_data_struct): Make is_space and is_subspace bitfields.
5922 Delete unused subspace_index. All references now use the
5923 target_index field within the section structure itself.
5925 * som.c (make_unique_section): Delete unused declaration.
5926 (som_bfd_copy_private_bfd_data): New function.
5927 (som_object_setup): Allocate space for and save exec information
5928 that needs to be copied during objcopy/strip.
5929 (som_mkobject): Do not allocate space for a file header here.
5930 It is not used when only reading SOM objects.
5931 (som_prep_headers): Allocate space for and attach a file header
5932 to the output bfd. For executables, use the saved system_id
5933 value rather than trying to guess the right value. Do not abort
5934 wwhen setting file_hdr->entry* for executables.
5935 (som_begin_writing): For executables, set the exec_entry and
5937 (som_copy_private_backend_section_data): Always return a value.
5939 * libhppa.h (PA_PAGESIZE): Define.
5941 * som.c (SOM_ALIGN): Define.
5942 (som_begin_writing): If writing an executable, initialize all
5943 fields in the exec header to zero. Update fields in the exec
5944 header as sizes of loadable subspaces are computed. Carefully
5945 preserve alignments when building executables. Actually write the
5946 exec after all the fields are filled in.
5948 * Better long-filename handling. Reads SOM ABI compliant extended
5949 names, but doesn't quite write compliant extended names yet.
5950 * som.c (som_slurp_extended_name_table): Delete function. The
5951 generic code will handle things correctly.
5952 (som_slurp_armap): Seek to the beginning of the next member.
5953 (normalize): New function.
5954 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5955 name table into account when computing the file offsets in the
5956 SOM dictionary. Make sure to align to an even boundary.
5957 (som_write_armap): Initialize the checksum to zero.
5958 (ar_maxchars): Fix. Opps.
5960 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5962 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5963 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5965 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5967 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5968 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5969 * bfd-in2.h: Regenerated.
5971 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5972 this was also named trad_unix_bfd_copy_private_bfd_data.
5974 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5976 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5977 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5978 returns NULL, it is not an error. It's possible that some of
5979 these checks are not necessary (because the size can never be
5980 zero), but putting in the checks is the conservative thing to do
5981 in light of the fact that some of these malloc calls replaced
5982 unchecked alloca calls, in which a zero argument would work fine.
5984 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5986 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5987 duplicate definition.
5988 (osf_core_bfd_is_local_label): Define.
5990 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5991 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5992 failure indication, it merely means there are no relocs.
5994 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5995 after NAME, since SunOS /bin/cc can't handle it.
5997 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5999 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6000 From sukes@glue.umd.edu (Tasuki Hirata).
6002 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6004 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6005 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6006 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6008 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6010 * som.c (som_prep_for_fixups): Detect section symbols based
6011 on either the lack of private data or the symbol flags. Do not
6012 munge section symbol names anymore -- they no longer confuse GDB.
6013 (som_begin_writing): Leave space for an exec header if writing
6015 (som_slurp_symbol_table): Recognize both forms of section symbol
6016 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6017 section symbols to be the name of the section they represent.
6018 Debugging symbols begin with "L$0\001", not just "L$".
6020 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6022 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6024 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6025 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6026 and bfd_is_local_label.
6028 * targets.c: Add new entries to the bfd_target structure.
6030 * bfd.c (bfd_copy_private_bfd_data): New definition.
6032 * section.c (bfd_copy_private_section_data): New definition.
6034 * syms.c (bfd_is_local_label): New definition.
6036 * libbfd-in.h (bfd_generic_is_local_label): Declare.
6038 * libbfd.c (bfd_generic_is_local_label): New function.
6040 * *-core.c: Provide default definitions for new functions in
6041 the target vector which all point to bfd_false.
6043 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6044 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6045 Default new vectors for copying private backend data to bfd_true.
6046 Default new vector for determining if a symbol is a local label
6047 to bfd_generic_is_local_label.
6049 * som.c (som_bfd_copy_private_section_data): New function.
6050 (som_bfd_is_local_label): New function.
6051 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6053 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6055 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6057 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6059 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6062 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6063 Indent some of them to GNU standards.
6065 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6066 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6067 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6068 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6069 Update copyright years.
6071 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6073 * som.c (som_prep_for_fixups): A relocation involving the section
6074 symbol for the *ABS* section is really a relocation involving
6076 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6077 undefined symbols. Correctly distinguish between debugger symbols
6078 and section symbols.
6080 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6081 for spaces and subspaces.
6083 * som.c (som_bfd_count_ar_symbols): Fix typo.
6085 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6086 HAS_RELOC based on the object's magic number.
6087 (make_unique_section): Delete function. BFD and its users are
6088 prepared to handle multiple sections with the same name.
6089 (setup_sections): Allocate space on the BFD's obstack to hold
6090 section names. Use bfd_make_setion_anyway rather than the
6091 obsolete make_unique_section.
6092 (som_prep_headers): Choose the correct SOM magic number based
6094 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6096 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6098 * elf32-ppc.c: Renamed from elf32-powerpc.c.
6099 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
6100 * Makefile.in, configure.in: Corresponding changes.

6104 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
6106 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6108 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6109 is always located at the start of the data section to allow
6110 recovery of the dynamic info from a stripped executable.
6111 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6114 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6116 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6117 cruft (like the #pragma alloca for AIX).
6118 In addition to that problem, the C alloca calls xmalloc, which
6119 means checking for being out of memory can't work right. The
6120 following changes remove all uses of alloca from BFD.
6121 * hosts/solaris2.h: Remove alloca cruft.
6122 * som.c: Replace alloca with a fixed size auto array.
6123 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

6125 sunos.c: Replace alloca with malloc and appropriate error checking and
6127 * linker.c: Replace alloca with obstack_alloc.

6471 bother processing them.
6472 (b_out_get_relocated_section_contents): Set reloc_done. Assert

7175 The sparc (and possibly other?) NLM format requires a different
7176 way to write exports, so add a write_export field to the backend
7177 data (and set it to NULL for everything but the sparc).

7343 sym_filepos as well.
7344 (ecoff_get_extr): Use ifdmap instead of ifdbase.

7421 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
7422 different, so there is no point to providing a generic one.
7423 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
7424 in the backend accessor macros; that should no longer be possible.
