1309 an empty .plt section.
1310 (elf32_sparc_relocate_section): For a GOT reloc against a global
1311 symbol when no dynamic object was seen, initialize the contents of
1312 the .got section. For a GOT reloc against a local symbol, only

4885 extended name table.
4887 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4889 Support for link_order types which generate relocs in order to
4890 support -Ur in the linker.
4891 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4892 from call to _bfd_generic_link_add_one_symbol.
4893 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4894 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4895 instead of bitsize to add_to_set call back.
4896 (_bfd_generic_final_link): Account for link_order relocs when
4897 allocating space for relocations. Handle them in link_order loop.
4898 (_bfd_generic_reloc_link_order): New function.

4916 allocating space for relocations. Handle them in link_order loop.
4917 (ecoff_link_write_external): Set the storage class of a defined
4918 linker created symbol based on the section it is in. Correct
4919 bfd_link_hash_weak case to use .sc rather than .st.

4936 * som.c (bfd_section_from_som_symbol): Only to do the value
4937 comparison for function symbols within executables.
4939 * som.c (bfd_section_from_som_symbol): Renamed from
4940 som_section_from_subspace_index. Pass in a native SOM symbol.
4941 For executables, iterate through the sections to find out
4942 which contains the symbol's address rather than using the
4943 symbol_info field. (symbol_info has a different meaning for
4944 dynamicly linked executables.)
4946 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4949 * som.c (som_begin_writing): Fix braino (one call to align
4950 space/subspace data was done unconditionally rather than
4951 just for executables.)
4953 * som.c (som_begin_writing): Align text in all executables to
4954 make HPUX kernel happy. Fixes strip/objcopy for shared
4957 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4959 * som.c (som_begin_writing): Account for alignment needs of
4960 subspaces too when writing executables. Never request a negative
4961 bss size. Fixes some problems with demand paged executables,
4962 still having problems with pure executables and shared executables.
4964 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4966 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4967 bfd_zalloc for rawptr, because later on we may call free, not
4970 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4971 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4972 * cisco-core.c: New file.
4973 * Makefile.in: Change accordingly.
4974 * configure.in: Recognize cisco_core_vec.
4975 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4976 * targets.c: Add cisco_core_vec.

4979 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4981 * som.h (som_copyable_section_data_struct): New structure
4982 containing all the private section information which needs
4983 to be copied from input section to output section during
4985 (som_section_data_struct): Remove several fields now in
4986 som_copyable_section_data_struct. Make the space and
4987 subspace dictionaries be pointers (to save space when
4988 only reading objects).
4990 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4991 some references changed. Allocate a copyable data stucture if
4992 none exists. Store info into the copyable data structure.
4993 (bfd_som_set_subsection_attributes): Likewise.
4994 (som_is_space, som_is_subspace, som_is_container): New functions.
4995 Use these instead of directly accessing private data.
4996 (som_prep_headers): Allocate space and subspace headers here.
4997 Fill in some fields in the space/subspace headers from the
4999 (som_bfd_copy_private_section_data): Only copy the stuff
5000 that we really need to make objcopy and strip work. Allocate
5001 the copy_data structure for the output bfd before copying.
5003 * som.h (struct som_exec_data): New structure to hold exec
5004 info that must be preserved when running objcopy/strip.
5005 (struct somdata): Add new "exec_data" field and accessor
5006 macro. Add some comments on how the various fields are used.
5007 (som_section_data_struct): Make is_space and is_subspace bitfields.
5008 Delete unused subspace_index. All references now use the
5009 target_index field within the section structure itself.
5011 * som.c (make_unique_section): Delete unused declaration.
5012 (som_bfd_copy_private_bfd_data): New function.
5013 (som_object_setup): Allocate space for and save exec information
5014 that needs to be copied during objcopy/strip.
5015 (som_mkobject): Do not allocate space for a file header here.
5016 It is not used when only reading SOM objects.
5017 (som_prep_headers): Allocate space for and attach a file header
5018 to the output bfd. For executables, use the saved system_id
5019 value rather than trying to guess the right value. Do not abort
5020 wwhen setting file_hdr->entry* for executables.
5021 (som_begin_writing): For executables, set the exec_entry and
5023 (som_copy_private_backend_section_data): Always return a value.
5025 * libhppa.h (PA_PAGESIZE): Define.
5027 * som.c (SOM_ALIGN): Define.
5028 (som_begin_writing): If writing an executable, initialize all
5029 fields in the exec header to zero. Update fields in the exec
5030 header as sizes of loadable subspaces are computed. Carefully
5031 preserve alignments when building executables. Actually write the
5032 exec after all the fields are filled in.
5034 * Better long-filename handling. Reads SOM ABI compliant extended
5035 names, but doesn't quite write compliant extended names yet.
5036 * som.c (som_slurp_extended_name_table): Delete function. The
5037 generic code will handle things correctly.
5038 (som_slurp_armap): Seek to the beginning of the next member.
5039 (normalize): New function.
5040 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5041 name table into account when computing the file offsets in the
5042 SOM dictionary. Make sure to align to an even boundary.
5043 (som_write_armap): Initialize the checksum to zero.
5044 (ar_maxchars): Fix. Opps.
5046 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5048 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5049 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5051 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5053 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5054 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5055 * bfd-in2.h: Regenerated.
5057 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5058 this was also named trad_unix_bfd_copy_private_bfd_data.
5060 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5062 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5063 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5064 returns NULL, it is not an error. It's possible that some of
5065 these checks are not necessary (because the size can never be
5066 zero), but putting in the checks is the conservative thing to do
5067 in light of the fact that some of these malloc calls replaced
5068 unchecked alloca calls, in which a zero argument would work fine.
5070 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5072 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5073 duplicate definition.
5074 (osf_core_bfd_is_local_label): Define.
5076 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5077 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5078 failure indication, it merely means there are no relocs.
5080 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5081 after NAME, since SunOS /bin/cc can't handle it.
5083 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5085 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5086 From sukes@glue.umd.edu (Tasuki Hirata).
5088 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5090 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5091 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5092 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5094 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5096 * som.c (som_prep_for_fixups): Detect section symbols based
5097 on either the lack of private data or the symbol flags. Do not
5098 munge section symbol names anymore -- they no longer confuse GDB.
5099 (som_begin_writing): Leave space for an exec header if writing
5101 (som_slurp_symbol_table): Recognize both forms of section symbol
5102 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5103 section symbols to be the name of the section they represent.
5104 Debugging symbols begin with "L$0\001", not just "L$".
5106 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5108 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5110 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5111 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5112 and bfd_is_local_label.
5114 * targets.c: Add new entries to the bfd_target structure.
5116 * bfd.c (bfd_copy_private_bfd_data): New definition.
5118 * section.c (bfd_copy_private_section_data): New definition.

5122 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5124 * libbfd.c (bfd_generic_is_local_label): New function.
5126 * *-core.c: Provide default definitions for new functions in
5127 the target vector which all point to bfd_false.
5129 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5130 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5131 Default new vectors for copying private backend data to bfd_true.
5132 Default new vector for determining if a symbol is a local label
5133 to bfd_generic_is_local_label.
5135 * som.c (som_bfd_copy_private_section_data): New function.
5136 (som_bfd_is_local_label): New function.
5137 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5139 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5141 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5143 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5145 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5148 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5149 Indent some of them to GNU standards.
5151 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5152 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5153 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5154 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5155 Update copyright years.
5157 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5159 * som.c (som_prep_for_fixups): A relocation involving the section
5160 symbol for the *ABS* section is really a relocation involving
5162 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5163 undefined symbols. Correctly distinguish between debugger symbols
5164 and section symbols.
5166 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5167 for spaces and subspaces.
5169 * som.c (som_bfd_count_ar_symbols): Fix typo.
5171 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5172 HAS_RELOC based on the object's magic number.
5173 (make_unique_section): Delete function. BFD and its users are
5174 prepared to handle multiple sections with the same name.
5175 (setup_sections): Allocate space on the BFD's obstack to hold
5176 section names. Use bfd_make_setion_anyway rather than the
5177 obsolete make_unique_section.
5178 (som_prep_headers): Choose the correct SOM magic number based
5180 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5182 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5184 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5194 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5195 is always located at the start of the data section to allow
5196 recovery of the dynamic info from a stripped executable.
5197 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5200 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5202 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5203 cruft (like the #pragma alloca for AIX).
5204 In addition to that problem, the C alloca calls xmalloc, which
5205 means checking for being out of memory can't work right. The
5206 following changes remove all uses of alloca from BFD.
5207 * hosts/solaris2.h: Remove alloca cruft.
5208 * som.c: Replace alloca with a fixed size auto array.
5209 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

5213 * linker.c: Replace alloca with obstack_alloc.
5214 * libbfd.h: Rebuilt.
5216 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5218 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5221 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5223 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,

5557 bother processing them.

6261 The sparc (and possibly other?) NLM format requires a different
6262 way to write exports, so add a write_export field to the backend
6263 data (and set it to NULL for everything but the sparc).
