1297 (elf_link_create_dynamic_sections): If dynamic sections were
1298 already created, don't do anything. If dynobj is already set, use
1299 it; otherwise, set it to the bfd argument. Don't initialize

1315 (elf_i386_create_got_section): New static function.
1316 (elf_i386_check_relocs): Just call elf_i386_create_got_section if
1317 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.

1344 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
1345 Only create the .rela.got section, and only make space for a
1346 reloc, for a global symbol or when generating a shared object.
1347 Set the alignment of the .rela.got section to 2. For a

1353 of the .plt section.
1354 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
1355 seen, skip most of this function, and force the size of the
1356 .rela.got section to zero. Strip empty reloc sections, and strip
1357 an empty .plt section.
1358 (elf32_sparc_relocate_section): For a GOT reloc against a global
1359 symbol when no dynamic object was seen, initialize the contents of
1360 the .got section. For a GOT reloc against a local symbol, only
1361 create a R_SPARC_RELATIVE reloc when generating a shared object.
1362 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1363 create a PLT entry as a R_SPARC_WDISP30 reloc.
1364 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
1365 dynamic entries and the PLT if we saw a dynamic object.

1377 Wed Oct 19 13:28:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1379 * coffgen.c (coff_print_symbol): Make names for section number and
1380 storage class slightly more verbose. It's not clear how many

4802 required by expansions. Set s and unset h when converting a reloc
4803 from undefined to section. Change handling of PC relative relocs:
4804 if against a section, they are correct in the object file, if
4805 against an external symbol they are pcrel_offset.
4806 (mips_relax_section): New function.
4807 (mips_relax_pcrel16): New function.

4892 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4893 reloc, used in embedded PIC code.
4894 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

4902 add_symbls entry point.
4904 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4905 counting relocs. Set SEC_RELOC flag for any section which has

4933 extended name table.
4935 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4937 Support for link_order types which generate relocs in order to
4938 support -Ur in the linker.
4939 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4940 from call to _bfd_generic_link_add_one_symbol.
4941 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4942 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4943 instead of bitsize to add_to_set call back.
4944 (_bfd_generic_final_link): Account for link_order relocs when
4945 allocating space for relocations. Handle them in link_order loop.
4946 (_bfd_generic_reloc_link_order): New function.

4964 allocating space for relocations. Handle them in link_order loop.
4965 (ecoff_link_write_external): Set the storage class of a defined
4966 linker created symbol based on the section it is in. Correct
4967 bfd_link_hash_weak case to use .sc rather than .st.
4968 (ecoff_reloc_link_order): New function.
4969 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4971 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4977 bfd_zmalloc. Free a pointer, not a union.
4978 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4980 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4982 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4984 * som.c (bfd_section_from_som_symbol): Only to do the value
4985 comparison for function symbols within executables.
4987 * som.c (bfd_section_from_som_symbol): Renamed from
4988 som_section_from_subspace_index. Pass in a native SOM symbol.
4989 For executables, iterate through the sections to find out
4990 which contains the symbol's address rather than using the
4991 symbol_info field. (symbol_info has a different meaning for
4992 dynamicly linked executables.)
4994 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4997 * som.c (som_begin_writing): Fix braino (one call to align
4998 space/subspace data was done unconditionally rather than
4999 just for executables.)
5001 * som.c (som_begin_writing): Align text in all executables to
5002 make HPUX kernel happy. Fixes strip/objcopy for shared
5005 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5007 * som.c (som_begin_writing): Account for alignment needs of
5008 subspaces too when writing executables. Never request a negative
5009 bss size. Fixes some problems with demand paged executables,
5010 still having problems with pure executables and shared executables.
5012 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5014 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5015 bfd_zalloc for rawptr, because later on we may call free, not
5018 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5019 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5020 * cisco-core.c: New file.
5021 * Makefile.in: Change accordingly.
5022 * configure.in: Recognize cisco_core_vec.
5023 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5024 * targets.c: Add cisco_core_vec.
5025 * bfd-in2.h: Rebuilt.
5027 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5029 * som.h (som_copyable_section_data_struct): New structure
5030 containing all the private section information which needs
5031 to be copied from input section to output section during
5033 (som_section_data_struct): Remove several fields now in
5034 som_copyable_section_data_struct. Make the space and
5035 subspace dictionaries be pointers (to save space when
5036 only reading objects).
5038 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5039 some references changed. Allocate a copyable data stucture if
5040 none exists. Store info into the copyable data structure.
5041 (bfd_som_set_subsection_attributes): Likewise.
5042 (som_is_space, som_is_subspace, som_is_container): New functions.
5043 Use these instead of directly accessing private data.
5044 (som_prep_headers): Allocate space and subspace headers here.
5045 Fill in some fields in the space/subspace headers from the
5047 (som_bfd_copy_private_section_data): Only copy the stuff
5048 that we really need to make objcopy and strip work. Allocate
5049 the copy_data structure for the output bfd before copying.
5051 * som.h (struct som_exec_data): New structure to hold exec
5052 info that must be preserved when running objcopy/strip.
5053 (struct somdata): Add new "exec_data" field and accessor
5054 macro. Add some comments on how the various fields are used.
5055 (som_section_data_struct): Make is_space and is_subspace bitfields.
5056 Delete unused subspace_index. All references now use the
5057 target_index field within the section structure itself.
5059 * som.c (make_unique_section): Delete unused declaration.
5060 (som_bfd_copy_private_bfd_data): New function.
5061 (som_object_setup): Allocate space for and save exec information
5062 that needs to be copied during objcopy/strip.
5063 (som_mkobject): Do not allocate space for a file header here.
5064 It is not used when only reading SOM objects.
5065 (som_prep_headers): Allocate space for and attach a file header
5066 to the output bfd. For executables, use the saved system_id
5067 value rather than trying to guess the right value. Do not abort
5068 wwhen setting file_hdr->entry* for executables.
5069 (som_begin_writing): For executables, set the exec_entry and
5071 (som_copy_private_backend_section_data): Always return a value.
5073 * libhppa.h (PA_PAGESIZE): Define.
5075 * som.c (SOM_ALIGN): Define.
5076 (som_begin_writing): If writing an executable, initialize all
5077 fields in the exec header to zero. Update fields in the exec
5078 header as sizes of loadable subspaces are computed. Carefully
5079 preserve alignments when building executables. Actually write the
5080 exec after all the fields are filled in.
5082 * Better long-filename handling. Reads SOM ABI compliant extended
5083 names, but doesn't quite write compliant extended names yet.
5084 * som.c (som_slurp_extended_name_table): Delete function. The
5085 generic code will handle things correctly.
5086 (som_slurp_armap): Seek to the beginning of the next member.
5087 (normalize): New function.
5088 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5089 name table into account when computing the file offsets in the
5090 SOM dictionary. Make sure to align to an even boundary.
5091 (som_write_armap): Initialize the checksum to zero.
5092 (ar_maxchars): Fix. Opps.
5094 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5096 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5097 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5099 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5101 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5102 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5103 * bfd-in2.h: Regenerated.
5105 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5106 this was also named trad_unix_bfd_copy_private_bfd_data.
5108 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5110 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5111 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5112 returns NULL, it is not an error. It's possible that some of
5113 these checks are not necessary (because the size can never be
5114 zero), but putting in the checks is the conservative thing to do
5115 in light of the fact that some of these malloc calls replaced
5116 unchecked alloca calls, in which a zero argument would work fine.
5118 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5120 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5121 duplicate definition.
5122 (osf_core_bfd_is_local_label): Define.
5124 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5125 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5126 failure indication, it merely means there are no relocs.
5128 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5129 after NAME, since SunOS /bin/cc can't handle it.
5131 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5133 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5134 From sukes@glue.umd.edu (Tasuki Hirata).
5136 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5138 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5139 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5140 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5142 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5144 * som.c (som_prep_for_fixups): Detect section symbols based
5145 on either the lack of private data or the symbol flags. Do not
5146 munge section symbol names anymore -- they no longer confuse GDB.
5147 (som_begin_writing): Leave space for an exec header if writing
5149 (som_slurp_symbol_table): Recognize both forms of section symbol
5150 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5151 section symbols to be the name of the section they represent.
5152 Debugging symbols begin with "L$0\001", not just "L$".
5154 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5156 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5158 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5159 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5160 and bfd_is_local_label.
5162 * targets.c: Add new entries to the bfd_target structure.

5175 the target vector which all point to bfd_false.
5177 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5178 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5179 Default new vectors for copying private backend data to bfd_true.
5180 Default new vector for determining if a symbol is a local label
5181 to bfd_generic_is_local_label.
5183 * som.c (som_bfd_copy_private_section_data): New function.
5184 (som_bfd_is_local_label): New function.
5185 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5187 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5189 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5191 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5193 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5196 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5197 Indent some of them to GNU standards.
5199 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5200 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5201 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5202 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5203 Update copyright years.
5205 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5207 * som.c (som_prep_for_fixups): A relocation involving the section
5208 symbol for the *ABS* section is really a relocation involving
5210 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5211 undefined symbols. Correctly distinguish between debugger symbols
5212 and section symbols.
5214 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5215 for spaces and subspaces.
5217 * som.c (som_bfd_count_ar_symbols): Fix typo.
5219 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5220 HAS_RELOC based on the object's magic number.
5221 (make_unique_section): Delete function. BFD and its users are
5222 prepared to handle multiple sections with the same name.

5251 cruft (like the #pragma alloca for AIX).
5252 In addition to that problem, the C alloca calls xmalloc, which

6139 (only testing for m68k and vax at the moment); do verify that the
6140 preprocessor didn't trash the arch name inside the string version.

6282 undefined, look it up in the linker hash table.
6284 * aoutx.h (translate_symbol_table): The string index 0 has a

6309 The sparc (and possibly other?) NLM format requires a different
6310 way to write exports, so add a write_export field to the backend
6311 data (and set it to NULL for everything but the sparc).

6419 the DYNAMIC flag for the BFD.

6472 * ecofflink.c: Extensive changes to compress and merge debugging
6473 information, and to write some of out directly rather than saving

6477 sym_filepos as well.
6478 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6544 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
6545 count it as a wrong format error, not a system call error, since
6546 the object file might simply be too small.
6548 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
6550 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

6553 * configure.in (nlm32_alpha_vec): Set target64 to true.
6555 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6556 different, so there is no point to providing a generic one.
6557 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL

7447 * elfcode.h (elf_object_p): Rather than looking through an array
7448 of architectures, get the ELF EM_xxx code from the backend
7449 information. Let the generic ELF target match any EM_xxx code not
