1293 (elf_link_create_dynamic_sections): If dynamic sections were
1294 already created, don't do anything. If dynobj is already set, use
1295 it; otherwise, set it to the bfd argument. Don't initialize

1311 (elf_i386_create_got_section): New static function.
1312 (elf_i386_check_relocs): Just call elf_i386_create_got_section if

1349 of the .plt section.
1350 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
1351 seen, skip most of this function, and force the size of the
1352 .rela.got section to zero. Strip empty reloc sections, and strip
1353 an empty .plt section.
1354 (elf32_sparc_relocate_section): For a GOT reloc against a global
1355 symbol when no dynamic object was seen, initialize the contents of
1356 the .got section. For a GOT reloc against a local symbol, only
1357 create a R_SPARC_RELATIVE reloc when generating a shared object.
1358 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1359 create a PLT entry as a R_SPARC_WDISP30 reloc.
1360 (elf32_sparc_finish_dynamic_sections): Only fiddle with the

1376 storage class slightly more verbose. It's not clear how many
1377 characters I can justify using up, but before this change they
1378 both were abbreviated "sc" which is (IMHO) clearly unacceptable.
1380 Wed Oct 19 01:26:39 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1382 * binary.c (binary_set_section_contents): Set the base file

4787 the debugging information if it has already been read.
4788 (ecoff_indirect_link_order): Handle _cooked_size being different

4798 required by expansions. Set s and unset h when converting a reloc
4799 from undefined to section. Change handling of PC relative relocs:
4800 if against a section, they are correct in the object file, if
4801 against an external symbol they are pcrel_offset.
4802 (mips_relax_section): New function.
4803 (mips_relax_pcrel16): New function.

4888 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4889 reloc, used in embedded PIC code.
4890 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

4897 link_order loop. Use _bfd_generic_link_add_symbols_collect for
4898 add_symbls entry point.
4900 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
4901 counting relocs. Set SEC_RELOC flag for any section which has

4929 extended name table.
4931 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4933 Support for link_order types which generate relocs in order to
4934 support -Ur in the linker.
4935 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4936 from call to _bfd_generic_link_add_one_symbol.
4937 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4938 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4939 instead of bitsize to add_to_set call back.
4940 (_bfd_generic_final_link): Account for link_order relocs when
4941 allocating space for relocations. Handle them in link_order loop.
4942 (_bfd_generic_reloc_link_order): New function.

4947 argument from declaration.
4948 (_bfd_generic_reloc_link_order): Declare.

4960 allocating space for relocations. Handle them in link_order loop.
4961 (ecoff_link_write_external): Set the storage class of a defined
4962 linker created symbol based on the section it is in. Correct
4963 bfd_link_hash_weak case to use .sc rather than .st.
4964 (ecoff_reloc_link_order): New function.
4965 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4967 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4973 bfd_zmalloc. Free a pointer, not a union.
4974 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4976 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4978 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4980 * som.c (bfd_section_from_som_symbol): Only to do the value
4981 comparison for function symbols within executables.
4983 * som.c (bfd_section_from_som_symbol): Renamed from
4984 som_section_from_subspace_index. Pass in a native SOM symbol.
4985 For executables, iterate through the sections to find out
4986 which contains the symbol's address rather than using the
4987 symbol_info field. (symbol_info has a different meaning for
4988 dynamicly linked executables.)
4990 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4993 * som.c (som_begin_writing): Fix braino (one call to align
4994 space/subspace data was done unconditionally rather than
4995 just for executables.)
4997 * som.c (som_begin_writing): Align text in all executables to
4998 make HPUX kernel happy. Fixes strip/objcopy for shared
5001 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5003 * som.c (som_begin_writing): Account for alignment needs of
5004 subspaces too when writing executables. Never request a negative
5005 bss size. Fixes some problems with demand paged executables,
5006 still having problems with pure executables and shared executables.
5008 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5010 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5011 bfd_zalloc for rawptr, because later on we may call free, not
5014 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5015 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5016 * cisco-core.c: New file.
5017 * Makefile.in: Change accordingly.
5018 * configure.in: Recognize cisco_core_vec.
5019 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5020 * targets.c: Add cisco_core_vec.
5021 * bfd-in2.h: Rebuilt.
5023 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5025 * som.h (som_copyable_section_data_struct): New structure
5026 containing all the private section information which needs
5027 to be copied from input section to output section during
5029 (som_section_data_struct): Remove several fields now in
5030 som_copyable_section_data_struct. Make the space and
5031 subspace dictionaries be pointers (to save space when
5032 only reading objects).
5034 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5035 some references changed. Allocate a copyable data stucture if
5036 none exists. Store info into the copyable data structure.
5037 (bfd_som_set_subsection_attributes): Likewise.
5038 (som_is_space, som_is_subspace, som_is_container): New functions.
5039 Use these instead of directly accessing private data.
5040 (som_prep_headers): Allocate space and subspace headers here.
5041 Fill in some fields in the space/subspace headers from the
5043 (som_bfd_copy_private_section_data): Only copy the stuff
5044 that we really need to make objcopy and strip work. Allocate
5045 the copy_data structure for the output bfd before copying.
5047 * som.h (struct som_exec_data): New structure to hold exec
5048 info that must be preserved when running objcopy/strip.
5049 (struct somdata): Add new "exec_data" field and accessor
5050 macro. Add some comments on how the various fields are used.
5051 (som_section_data_struct): Make is_space and is_subspace bitfields.
5052 Delete unused subspace_index. All references now use the
5053 target_index field within the section structure itself.
5055 * som.c (make_unique_section): Delete unused declaration.
5056 (som_bfd_copy_private_bfd_data): New function.
5057 (som_object_setup): Allocate space for and save exec information
5058 that needs to be copied during objcopy/strip.
5059 (som_mkobject): Do not allocate space for a file header here.
5060 It is not used when only reading SOM objects.
5061 (som_prep_headers): Allocate space for and attach a file header
5062 to the output bfd. For executables, use the saved system_id
5063 value rather than trying to guess the right value. Do not abort
5064 wwhen setting file_hdr->entry* for executables.
5065 (som_begin_writing): For executables, set the exec_entry and
5067 (som_copy_private_backend_section_data): Always return a value.
5069 * libhppa.h (PA_PAGESIZE): Define.
5071 * som.c (SOM_ALIGN): Define.
5072 (som_begin_writing): If writing an executable, initialize all
5073 fields in the exec header to zero. Update fields in the exec
5074 header as sizes of loadable subspaces are computed. Carefully
5075 preserve alignments when building executables. Actually write the
5076 exec after all the fields are filled in.
5078 * Better long-filename handling. Reads SOM ABI compliant extended
5079 names, but doesn't quite write compliant extended names yet.
5080 * som.c (som_slurp_extended_name_table): Delete function. The
5081 generic code will handle things correctly.
5082 (som_slurp_armap): Seek to the beginning of the next member.
5083 (normalize): New function.
5084 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5085 name table into account when computing the file offsets in the
5086 SOM dictionary. Make sure to align to an even boundary.
5087 (som_write_armap): Initialize the checksum to zero.
5088 (ar_maxchars): Fix. Opps.
5090 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5092 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5093 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5095 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5097 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5098 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5099 * bfd-in2.h: Regenerated.
5101 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5102 this was also named trad_unix_bfd_copy_private_bfd_data.
5104 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5106 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5107 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5108 returns NULL, it is not an error. It's possible that some of
5109 these checks are not necessary (because the size can never be
5110 zero), but putting in the checks is the conservative thing to do
5111 in light of the fact that some of these malloc calls replaced
5112 unchecked alloca calls, in which a zero argument would work fine.
5114 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5116 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5117 duplicate definition.
5118 (osf_core_bfd_is_local_label): Define.
5120 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5121 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5122 failure indication, it merely means there are no relocs.
5124 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5125 after NAME, since SunOS /bin/cc can't handle it.
5127 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5129 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5130 From sukes@glue.umd.edu (Tasuki Hirata).
5132 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5134 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5135 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5136 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5138 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5140 * som.c (som_prep_for_fixups): Detect section symbols based
5141 on either the lack of private data or the symbol flags. Do not
5142 munge section symbol names anymore -- they no longer confuse GDB.
5143 (som_begin_writing): Leave space for an exec header if writing
5145 (som_slurp_symbol_table): Recognize both forms of section symbol
5146 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5147 section symbols to be the name of the section they represent.
5148 Debugging symbols begin with "L$0\001", not just "L$".
5150 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5152 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5154 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5155 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5156 and bfd_is_local_label.
5158 * targets.c: Add new entries to the bfd_target structure.

5174 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5175 Default new vectors for copying private backend data to bfd_true.
5176 Default new vector for determining if a symbol is a local label
5177 to bfd_generic_is_local_label.
5179 * som.c (som_bfd_copy_private_section_data): New function.
5180 (som_bfd_is_local_label): New function.
5181 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5183 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5185 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5187 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5189 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5192 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5193 Indent some of them to GNU standards.
5195 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5196 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5197 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5198 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5199 Update copyright years.
5201 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5203 * som.c (som_prep_for_fixups): A relocation involving the section
5204 symbol for the *ABS* section is really a relocation involving
5206 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5207 undefined symbols. Correctly distinguish between debugger symbols
5208 and section symbols.
5210 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5211 for spaces and subspaces.
5213 * som.c (som_bfd_count_ar_symbols): Fix typo.
5215 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5216 HAS_RELOC based on the object's magic number.
5217 (make_unique_section): Delete function. BFD and its users are
5218 prepared to handle multiple sections with the same name.
5219 (setup_sections): Allocate space on the BFD's obstack to hold
5220 section names. Use bfd_make_setion_anyway rather than the
5221 obsolete make_unique_section.
5222 (som_prep_headers): Choose the correct SOM magic number based
5224 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5247 cruft (like the #pragma alloca for AIX).
5248 In addition to that problem, the C alloca calls xmalloc, which

6135 (only testing for m68k and vax at the moment); do verify that the
6136 preprocessor didn't trash the arch name inside the string version.

6138 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
6140 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

6278 undefined, look it up in the linker hash table.
6280 * aoutx.h (translate_symbol_table): The string index 0 has a

6305 The sparc (and possibly other?) NLM format requires a different
6306 way to write exports, so add a write_export field to the backend
6307 data (and set it to NULL for everything but the sparc).

6468 * ecofflink.c: Extensive changes to compress and merge debugging
6469 information, and to write some of out directly rather than saving

6473 sym_filepos as well.
6474 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6544 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
6546 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

6549 * configure.in (nlm32_alpha_vec): Set target64 to true.
6551 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6552 different, so there is no point to providing a generic one.
6553 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6554 in the backend accessor macros; that should no longer be possible.
6555 * targets.c (target_vector): Removed nlm32_big_generic_vec,
6556 nlm64_big_generic_vec, nlm64_little_generic_vec.

7443 * elfcode.h (elf_object_p): Rather than looking through an array
7444 of architectures, get the ELF EM_xxx code from the backend
