1312 of the .plt section.
1313 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
1314 seen, skip most of this function, and force the size of the

1316 an empty .plt section.
1317 (elf32_sparc_relocate_section): For a GOT reloc against a global
1318 symbol when no dynamic object was seen, initialize the contents of
1319 the .got section. For a GOT reloc against a local symbol, only

4849 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4851 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4852 reloc, used in embedded PIC code.

4872 _bfd_generic_link_add_symbols but also collect constructors and
4873 destructors by name as collect2 does.

4892 extended name table.
4894 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4896 Support for link_order types which generate relocs in order to
4897 support -Ur in the linker.
4898 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4899 from call to _bfd_generic_link_add_one_symbol.
4900 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4901 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4902 instead of bitsize to add_to_set call back.
4903 (_bfd_generic_final_link): Account for link_order relocs when
4904 allocating space for relocations. Handle them in link_order loop.
4905 (_bfd_generic_reloc_link_order): New function.

4923 allocating space for relocations. Handle them in link_order loop.
4924 (ecoff_link_write_external): Set the storage class of a defined
4925 linker created symbol based on the section it is in. Correct
4926 bfd_link_hash_weak case to use .sc rather than .st.

4939 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4941 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4943 * som.c (bfd_section_from_som_symbol): Only to do the value
4944 comparison for function symbols within executables.
4946 * som.c (bfd_section_from_som_symbol): Renamed from
4947 som_section_from_subspace_index. Pass in a native SOM symbol.
4948 For executables, iterate through the sections to find out
4949 which contains the symbol's address rather than using the
4950 symbol_info field. (symbol_info has a different meaning for
4951 dynamicly linked executables.)
4953 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4956 * som.c (som_begin_writing): Fix braino (one call to align
4957 space/subspace data was done unconditionally rather than
4958 just for executables.)
4960 * som.c (som_begin_writing): Align text in all executables to
4961 make HPUX kernel happy. Fixes strip/objcopy for shared
4964 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4966 * som.c (som_begin_writing): Account for alignment needs of
4967 subspaces too when writing executables. Never request a negative
4968 bss size. Fixes some problems with demand paged executables,
4969 still having problems with pure executables and shared executables.
4971 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4973 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4974 bfd_zalloc for rawptr, because later on we may call free, not
4977 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4978 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4979 * cisco-core.c: New file.
4980 * Makefile.in: Change accordingly.
4981 * configure.in: Recognize cisco_core_vec.
4982 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4983 * targets.c: Add cisco_core_vec.
4984 * bfd-in2.h: Rebuilt.
4986 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4988 * som.h (som_copyable_section_data_struct): New structure
4989 containing all the private section information which needs
4990 to be copied from input section to output section during
4992 (som_section_data_struct): Remove several fields now in
4993 som_copyable_section_data_struct. Make the space and
4994 subspace dictionaries be pointers (to save space when
4995 only reading objects).
4997 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4998 some references changed. Allocate a copyable data stucture if
4999 none exists. Store info into the copyable data structure.
5000 (bfd_som_set_subsection_attributes): Likewise.
5001 (som_is_space, som_is_subspace, som_is_container): New functions.
5002 Use these instead of directly accessing private data.
5003 (som_prep_headers): Allocate space and subspace headers here.
5004 Fill in some fields in the space/subspace headers from the
5006 (som_bfd_copy_private_section_data): Only copy the stuff
5007 that we really need to make objcopy and strip work. Allocate
5008 the copy_data structure for the output bfd before copying.
5010 * som.h (struct som_exec_data): New structure to hold exec
5011 info that must be preserved when running objcopy/strip.
5012 (struct somdata): Add new "exec_data" field and accessor
5013 macro. Add some comments on how the various fields are used.
5014 (som_section_data_struct): Make is_space and is_subspace bitfields.
5015 Delete unused subspace_index. All references now use the
5016 target_index field within the section structure itself.
5018 * som.c (make_unique_section): Delete unused declaration.
5019 (som_bfd_copy_private_bfd_data): New function.
5020 (som_object_setup): Allocate space for and save exec information
5021 that needs to be copied during objcopy/strip.
5022 (som_mkobject): Do not allocate space for a file header here.
5023 It is not used when only reading SOM objects.
5024 (som_prep_headers): Allocate space for and attach a file header
5025 to the output bfd. For executables, use the saved system_id
5026 value rather than trying to guess the right value. Do not abort
5027 wwhen setting file_hdr->entry* for executables.
5028 (som_begin_writing): For executables, set the exec_entry and
5030 (som_copy_private_backend_section_data): Always return a value.
5032 * libhppa.h (PA_PAGESIZE): Define.
5034 * som.c (SOM_ALIGN): Define.
5035 (som_begin_writing): If writing an executable, initialize all
5036 fields in the exec header to zero. Update fields in the exec
5037 header as sizes of loadable subspaces are computed. Carefully
5038 preserve alignments when building executables. Actually write the
5039 exec after all the fields are filled in.
5041 * Better long-filename handling. Reads SOM ABI compliant extended
5042 names, but doesn't quite write compliant extended names yet.
5043 * som.c (som_slurp_extended_name_table): Delete function. The
5044 generic code will handle things correctly.
5045 (som_slurp_armap): Seek to the beginning of the next member.
5046 (normalize): New function.
5047 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5048 name table into account when computing the file offsets in the
5049 SOM dictionary. Make sure to align to an even boundary.
5050 (som_write_armap): Initialize the checksum to zero.
5051 (ar_maxchars): Fix. Opps.
5053 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5055 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5056 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5058 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5060 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5061 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5062 * bfd-in2.h: Regenerated.
5064 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5065 this was also named trad_unix_bfd_copy_private_bfd_data.
5067 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5069 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5070 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5071 returns NULL, it is not an error. It's possible that some of
5072 these checks are not necessary (because the size can never be
5073 zero), but putting in the checks is the conservative thing to do
5074 in light of the fact that some of these malloc calls replaced
5075 unchecked alloca calls, in which a zero argument would work fine.
5077 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5079 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5080 duplicate definition.
5081 (osf_core_bfd_is_local_label): Define.
5083 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5084 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5085 failure indication, it merely means there are no relocs.
5087 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5088 after NAME, since SunOS /bin/cc can't handle it.
5090 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5092 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5093 From sukes@glue.umd.edu (Tasuki Hirata).
5095 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5097 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5098 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5099 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5101 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5103 * som.c (som_prep_for_fixups): Detect section symbols based
5104 on either the lack of private data or the symbol flags. Do not
5105 munge section symbol names anymore -- they no longer confuse GDB.
5106 (som_begin_writing): Leave space for an exec header if writing
5108 (som_slurp_symbol_table): Recognize both forms of section symbol
5109 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5110 section symbols to be the name of the section they represent.
5111 Debugging symbols begin with "L$0\001", not just "L$".
5113 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5115 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5117 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5118 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5119 and bfd_is_local_label.
5121 * targets.c: Add new entries to the bfd_target structure.
5123 * bfd.c (bfd_copy_private_bfd_data): New definition.
5125 * section.c (bfd_copy_private_section_data): New definition.
5127 * syms.c (bfd_is_local_label): New definition.
5129 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5131 * libbfd.c (bfd_generic_is_local_label): New function.
5133 * *-core.c: Provide default definitions for new functions in
5134 the target vector which all point to bfd_false.
5136 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5137 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5138 Default new vectors for copying private backend data to bfd_true.
5139 Default new vector for determining if a symbol is a local label
5140 to bfd_generic_is_local_label.
5142 * som.c (som_bfd_copy_private_section_data): New function.
5143 (som_bfd_is_local_label): New function.
5144 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5146 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5148 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5150 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5152 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5155 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5156 Indent some of them to GNU standards.
5158 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5159 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5160 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5161 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5162 Update copyright years.
5164 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5166 * som.c (som_prep_for_fixups): A relocation involving the section
5167 symbol for the *ABS* section is really a relocation involving
5169 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5170 undefined symbols. Correctly distinguish between debugger symbols
5171 and section symbols.
5173 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5174 for spaces and subspaces.
5176 * som.c (som_bfd_count_ar_symbols): Fix typo.
5178 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5179 HAS_RELOC based on the object's magic number.
5180 (make_unique_section): Delete function. BFD and its users are
5181 prepared to handle multiple sections with the same name.
5182 (setup_sections): Allocate space on the BFD's obstack to hold
5183 section names. Use bfd_make_setion_anyway rather than the
5184 obsolete make_unique_section.
5185 (som_prep_headers): Choose the correct SOM magic number based
5187 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5189 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5191 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5192 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5193 * Makefile.in, configure.in: Corresponding changes.

5197 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5199 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5201 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5202 is always located at the start of the data section to allow
5203 recovery of the dynamic info from a stripped executable.
5204 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5207 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5209 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5210 cruft (like the #pragma alloca for AIX).
5211 In addition to that problem, the C alloca calls xmalloc, which
5212 means checking for being out of memory can't work right. The
5213 following changes remove all uses of alloca from BFD.
5214 * hosts/solaris2.h: Remove alloca cruft.
5215 * som.c: Replace alloca with a fixed size auto array.
5216 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

6268 The sparc (and possibly other?) NLM format requires a different
6269 way to write exports, so add a write_export field to the backend
6270 data (and set it to NULL for everything but the sparc).

6436 sym_filepos as well.
6437 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6514 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6515 different, so there is no point to providing a generic one.
6516 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6517 in the backend accessor macros; that should no longer be possible.
