2233 of the .plt section.
2234 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
2235 seen, skip most of this function, and force the size of the

2237 an empty .plt section.
2238 (elf32_sparc_relocate_section): For a GOT reloc against a global
2239 symbol when no dynamic object was seen, initialize the contents of
2240 the .got section. For a GOT reloc against a local symbol, only

2242 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2243 create a PLT entry as a R_SPARC_WDISP30 reloc.

5682 required by expansions. Set s and unset h when converting a reloc
5683 from undefined to section. Change handling of PC relative relocs:
5684 if against a section, they are correct in the object file, if
5685 against an external symbol they are pcrel_offset.

5815 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5817 Support for link_order types which generate relocs in order to
5818 support -Ur in the linker.
5819 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5820 from call to _bfd_generic_link_add_one_symbol.
5821 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5822 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5823 instead of bitsize to add_to_set call back.
5824 (_bfd_generic_final_link): Account for link_order relocs when
5825 allocating space for relocations. Handle them in link_order loop.
5826 (_bfd_generic_reloc_link_order): New function.

5844 allocating space for relocations. Handle them in link_order loop.
5845 (ecoff_link_write_external): Set the storage class of a defined
5846 linker created symbol based on the section it is in. Correct
5847 bfd_link_hash_weak case to use .sc rather than .st.

5865 comparison for function symbols within executables.
5867 * som.c (bfd_section_from_som_symbol): Renamed from
5868 som_section_from_subspace_index. Pass in a native SOM symbol.
5869 For executables, iterate through the sections to find out
5870 which contains the symbol's address rather than using the
5871 symbol_info field. (symbol_info has a different meaning for
5872 dynamicly linked executables.)
5874 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5877 * som.c (som_begin_writing): Fix braino (one call to align
5878 space/subspace data was done unconditionally rather than
5879 just for executables.)
5881 * som.c (som_begin_writing): Align text in all executables to
5882 make HPUX kernel happy. Fixes strip/objcopy for shared
5885 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5887 * som.c (som_begin_writing): Account for alignment needs of
5888 subspaces too when writing executables. Never request a negative
5889 bss size. Fixes some problems with demand paged executables,
5890 still having problems with pure executables and shared executables.
5892 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5894 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5895 bfd_zalloc for rawptr, because later on we may call free, not
5898 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5899 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5900 * cisco-core.c: New file.

5907 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5909 * som.h (som_copyable_section_data_struct): New structure
5910 containing all the private section information which needs
5911 to be copied from input section to output section during
5913 (som_section_data_struct): Remove several fields now in
5914 som_copyable_section_data_struct. Make the space and
5915 subspace dictionaries be pointers (to save space when
5916 only reading objects).
5918 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5919 some references changed. Allocate a copyable data stucture if
5920 none exists. Store info into the copyable data structure.
5921 (bfd_som_set_subsection_attributes): Likewise.
5922 (som_is_space, som_is_subspace, som_is_container): New functions.
5923 Use these instead of directly accessing private data.
5924 (som_prep_headers): Allocate space and subspace headers here.
5925 Fill in some fields in the space/subspace headers from the
5927 (som_bfd_copy_private_section_data): Only copy the stuff
5928 that we really need to make objcopy and strip work. Allocate
5929 the copy_data structure for the output bfd before copying.
5931 * som.h (struct som_exec_data): New structure to hold exec
5932 info that must be preserved when running objcopy/strip.
5933 (struct somdata): Add new "exec_data" field and accessor
5934 macro. Add some comments on how the various fields are used.
5935 (som_section_data_struct): Make is_space and is_subspace bitfields.
5936 Delete unused subspace_index. All references now use the
5937 target_index field within the section structure itself.
5939 * som.c (make_unique_section): Delete unused declaration.
5940 (som_bfd_copy_private_bfd_data): New function.
5941 (som_object_setup): Allocate space for and save exec information
5942 that needs to be copied during objcopy/strip.
5943 (som_mkobject): Do not allocate space for a file header here.
5944 It is not used when only reading SOM objects.
5945 (som_prep_headers): Allocate space for and attach a file header
5946 to the output bfd. For executables, use the saved system_id
5947 value rather than trying to guess the right value. Do not abort
5948 wwhen setting file_hdr->entry* for executables.
5949 (som_begin_writing): For executables, set the exec_entry and
5951 (som_copy_private_backend_section_data): Always return a value.
5953 * libhppa.h (PA_PAGESIZE): Define.
5955 * som.c (SOM_ALIGN): Define.
5956 (som_begin_writing): If writing an executable, initialize all
5957 fields in the exec header to zero. Update fields in the exec
5958 header as sizes of loadable subspaces are computed. Carefully
5959 preserve alignments when building executables. Actually write the
5960 exec after all the fields are filled in.
5962 * Better long-filename handling. Reads SOM ABI compliant extended
5963 names, but doesn't quite write compliant extended names yet.
5964 * som.c (som_slurp_extended_name_table): Delete function. The
5965 generic code will handle things correctly.
5966 (som_slurp_armap): Seek to the beginning of the next member.
5967 (normalize): New function.
5968 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5969 name table into account when computing the file offsets in the
5970 SOM dictionary. Make sure to align to an even boundary.
5971 (som_write_armap): Initialize the checksum to zero.
5972 (ar_maxchars): Fix. Opps.

5981 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5982 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5983 * bfd-in2.h: Regenerated.
5985 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5986 this was also named trad_unix_bfd_copy_private_bfd_data.
5988 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5990 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5991 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5992 returns NULL, it is not an error. It's possible that some of
5993 these checks are not necessary (because the size can never be
5994 zero), but putting in the checks is the conservative thing to do
5995 in light of the fact that some of these malloc calls replaced
5996 unchecked alloca calls, in which a zero argument would work fine.
5998 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6000 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6001 duplicate definition.
6002 (osf_core_bfd_is_local_label): Define.
6004 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6005 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6006 failure indication, it merely means there are no relocs.
6008 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6009 after NAME, since SunOS /bin/cc can't handle it.
6011 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6013 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6014 From sukes@glue.umd.edu (Tasuki Hirata).
6016 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6018 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6019 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6020 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6022 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6024 * som.c (som_prep_for_fixups): Detect section symbols based
6025 on either the lack of private data or the symbol flags. Do not
6026 munge section symbol names anymore -- they no longer confuse GDB.
6027 (som_begin_writing): Leave space for an exec header if writing
6029 (som_slurp_symbol_table): Recognize both forms of section symbol
6030 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6031 section symbols to be the name of the section they represent.
6032 Debugging symbols begin with "L$0\001", not just "L$".
6034 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

6039 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6040 and bfd_is_local_label.

6058 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6059 Default new vectors for copying private backend data to bfd_true.
6060 Default new vector for determining if a symbol is a local label
6061 to bfd_generic_is_local_label.
6063 * som.c (som_bfd_copy_private_section_data): New function.
6064 (som_bfd_is_local_label): New function.
6065 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6067 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6069 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6071 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6073 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6076 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6077 Indent some of them to GNU standards.
6079 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6080 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

6082 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6083 Update copyright years.

6087 * som.c (som_prep_for_fixups): A relocation involving the section
6088 symbol for the *ABS* section is really a relocation involving
6090 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6091 undefined symbols. Correctly distinguish between debugger symbols
6092 and section symbols.
6094 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6095 for spaces and subspaces.
6097 * som.c (som_bfd_count_ar_symbols): Fix typo.
6099 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6100 HAS_RELOC based on the object's magic number.
6101 (make_unique_section): Delete function. BFD and its users are
6102 prepared to handle multiple sections with the same name.
6103 (setup_sections): Allocate space on the BFD's obstack to hold
6104 section names. Use bfd_make_setion_anyway rather than the
6105 obsolete make_unique_section.
6106 (som_prep_headers): Choose the correct SOM magic number based
6108 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

6122 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6123 is always located at the start of the data section to allow

6131 cruft (like the #pragma alloca for AIX).
6132 In addition to that problem, the C alloca calls xmalloc, which
6133 means checking for being out of memory can't work right. The
6134 following changes remove all uses of alloca from BFD.

6484 (b_out_relax_section): If a section contains no relocations, don't
6485 bother processing them.
6486 (b_out_get_relocated_section_contents): Set reloc_done. Assert
6487 that bfd_get_section_contents returns true. Check that relocs are

6570 Make all callers of malloc or realloc (including via obstacks)
6571 check the result for NULL. Most set bfd_error to no_memory and
6572 return in that case; a few are harder to fix, and are marked

6576 hppa_elf_build_long_branch_stub): Check bfd_make_empty_symbol return.

7189 The sparc (and possibly other?) NLM format requires a different
7190 way to write exports, so add a write_export field to the backend
7191 data (and set it to NULL for everything but the sparc).

7357 sym_filepos as well.
7358 (ecoff_get_extr): Use ifdmap instead of ifdbase.

7430 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

7433 * configure.in (nlm32_alpha_vec): Set target64 to true.
7435 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
7436 different, so there is no point to providing a generic one.
7437 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
7438 in the backend accessor macros; that should no longer be possible.
7439 * targets.c (target_vector): Removed nlm32_big_generic_vec,
