3890 required by expansions. Set s and unset h when converting a reloc
3891 from undefined to section. Change handling of PC relative relocs:
3892 if against a section, they are correct in the object file, if
3893 against an external symbol they are pcrel_offset.
3894 (mips_relax_section): New function.
3895 (mips_relax_pcrel16): New function.

3980 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
3981 reloc, used in embedded PIC code.
3982 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

3990 add_symbls entry point.
3992 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3993 counting relocs. Set SEC_RELOC flag for any section which has

4021 extended name table.
4023 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4025 Support for link_order types which generate relocs in order to
4026 support -Ur in the linker.
4027 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4028 from call to _bfd_generic_link_add_one_symbol.
4029 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4030 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4031 instead of bitsize to add_to_set call back.
4032 (_bfd_generic_final_link): Account for link_order relocs when
4033 allocating space for relocations. Handle them in link_order loop.
4034 (_bfd_generic_reloc_link_order): New function.

4052 allocating space for relocations. Handle them in link_order loop.
4053 (ecoff_link_write_external): Set the storage class of a defined
4054 linker created symbol based on the section it is in. Correct
4055 bfd_link_hash_weak case to use .sc rather than .st.
4056 (ecoff_reloc_link_order): New function.
4057 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4059 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4065 bfd_zmalloc. Free a pointer, not a union.
4066 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4068 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4070 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4072 * som.c (bfd_section_from_som_symbol): Only to do the value
4073 comparison for function symbols within executables.
4075 * som.c (bfd_section_from_som_symbol): Renamed from
4076 som_section_from_subspace_index. Pass in a native SOM symbol.
4077 For executables, iterate through the sections to find out
4078 which contains the symbol's address rather than using the
4079 symbol_info field. (symbol_info has a different meaning for
4080 dynamicly linked executables.)
4082 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4085 * som.c (som_begin_writing): Fix braino (one call to align
4086 space/subspace data was done unconditionally rather than
4087 just for executables.)
4089 * som.c (som_begin_writing): Align text in all executables to
4090 make HPUX kernel happy. Fixes strip/objcopy for shared
4093 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4095 * som.c (som_begin_writing): Account for alignment needs of
4096 subspaces too when writing executables. Never request a negative
4097 bss size. Fixes some problems with demand paged executables,
4098 still having problems with pure executables and shared executables.
4100 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4102 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4103 bfd_zalloc for rawptr, because later on we may call free, not
4106 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4107 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4108 * cisco-core.c: New file.

4110 * configure.in: Recognize cisco_core_vec.
4111 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4112 * targets.c: Add cisco_core_vec.
4113 * bfd-in2.h: Rebuilt.
4115 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4117 * som.h (som_copyable_section_data_struct): New structure
4118 containing all the private section information which needs
4119 to be copied from input section to output section during
4121 (som_section_data_struct): Remove several fields now in
4122 som_copyable_section_data_struct. Make the space and
4123 subspace dictionaries be pointers (to save space when
4124 only reading objects).
4126 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4127 some references changed. Allocate a copyable data stucture if
4128 none exists. Store info into the copyable data structure.
4129 (bfd_som_set_subsection_attributes): Likewise.
4130 (som_is_space, som_is_subspace, som_is_container): New functions.
4131 Use these instead of directly accessing private data.
4132 (som_prep_headers): Allocate space and subspace headers here.
4133 Fill in some fields in the space/subspace headers from the
4135 (som_bfd_copy_private_section_data): Only copy the stuff
4136 that we really need to make objcopy and strip work. Allocate
4137 the copy_data structure for the output bfd before copying.
4139 * som.h (struct som_exec_data): New structure to hold exec
4140 info that must be preserved when running objcopy/strip.
4141 (struct somdata): Add new "exec_data" field and accessor
4142 macro. Add some comments on how the various fields are used.
4143 (som_section_data_struct): Make is_space and is_subspace bitfields.
4144 Delete unused subspace_index. All references now use the
4145 target_index field within the section structure itself.
4147 * som.c (make_unique_section): Delete unused declaration.
4148 (som_bfd_copy_private_bfd_data): New function.
4149 (som_object_setup): Allocate space for and save exec information
4150 that needs to be copied during objcopy/strip.
4151 (som_mkobject): Do not allocate space for a file header here.
4152 It is not used when only reading SOM objects.
4153 (som_prep_headers): Allocate space for and attach a file header
4154 to the output bfd. For executables, use the saved system_id
4155 value rather than trying to guess the right value. Do not abort
4156 wwhen setting file_hdr->entry* for executables.
4157 (som_begin_writing): For executables, set the exec_entry and
4159 (som_copy_private_backend_section_data): Always return a value.
4161 * libhppa.h (PA_PAGESIZE): Define.
4163 * som.c (SOM_ALIGN): Define.
4164 (som_begin_writing): If writing an executable, initialize all
4165 fields in the exec header to zero. Update fields in the exec
4166 header as sizes of loadable subspaces are computed. Carefully
4167 preserve alignments when building executables. Actually write the
4168 exec after all the fields are filled in.
4170 * Better long-filename handling. Reads SOM ABI compliant extended
4171 names, but doesn't quite write compliant extended names yet.
4172 * som.c (som_slurp_extended_name_table): Delete function. The
4173 generic code will handle things correctly.
4174 (som_slurp_armap): Seek to the beginning of the next member.
4175 (normalize): New function.
4176 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4177 name table into account when computing the file offsets in the
4178 SOM dictionary. Make sure to align to an even boundary.
4179 (som_write_armap): Initialize the checksum to zero.
4180 (ar_maxchars): Fix. Opps.
4182 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4184 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4185 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4187 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4189 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4190 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4191 * bfd-in2.h: Regenerated.
4193 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4194 this was also named trad_unix_bfd_copy_private_bfd_data.
4196 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4198 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4199 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4200 returns NULL, it is not an error. It's possible that some of
4201 these checks are not necessary (because the size can never be
4202 zero), but putting in the checks is the conservative thing to do
4203 in light of the fact that some of these malloc calls replaced
4204 unchecked alloca calls, in which a zero argument would work fine.
4206 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4208 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4209 duplicate definition.
4210 (osf_core_bfd_is_local_label): Define.
4212 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4213 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4214 failure indication, it merely means there are no relocs.
4216 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4217 after NAME, since SunOS /bin/cc can't handle it.
4219 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4221 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4222 From sukes@glue.umd.edu (Tasuki Hirata).
4224 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4226 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4227 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4228 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4230 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4232 * som.c (som_prep_for_fixups): Detect section symbols based
4233 on either the lack of private data or the symbol flags. Do not
4234 munge section symbol names anymore -- they no longer confuse GDB.
4235 (som_begin_writing): Leave space for an exec header if writing
4237 (som_slurp_symbol_table): Recognize both forms of section symbol
4238 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4239 section symbols to be the name of the section they represent.
4240 Debugging symbols begin with "L$0\001", not just "L$".
4242 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4244 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4246 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4247 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4248 and bfd_is_local_label.
4250 * targets.c: Add new entries to the bfd_target structure.

4263 the target vector which all point to bfd_false.
4265 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4266 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4267 Default new vectors for copying private backend data to bfd_true.
4268 Default new vector for determining if a symbol is a local label
4269 to bfd_generic_is_local_label.
4271 * som.c (som_bfd_copy_private_section_data): New function.
4272 (som_bfd_is_local_label): New function.
4273 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4275 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4277 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4279 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4281 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4284 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4285 Indent some of them to GNU standards.
4287 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4288 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4289 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4290 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4291 Update copyright years.
4293 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4295 * som.c (som_prep_for_fixups): A relocation involving the section
4296 symbol for the *ABS* section is really a relocation involving
4298 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4299 undefined symbols. Correctly distinguish between debugger symbols
4300 and section symbols.
4302 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4303 for spaces and subspaces.
4305 * som.c (som_bfd_count_ar_symbols): Fix typo.
4307 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4308 HAS_RELOC based on the object's magic number.
4309 (make_unique_section): Delete function. BFD and its users are
4310 prepared to handle multiple sections with the same name.

4339 cruft (like the #pragma alloca for AIX).
4340 In addition to that problem, the C alloca calls xmalloc, which

5227 (only testing for m68k and vax at the moment); do verify that the
5228 preprocessor didn't trash the arch name inside the string version.

5370 undefined, look it up in the linker hash table.
5372 * aoutx.h (translate_symbol_table): The string index 0 has a

5397 The sparc (and possibly other?) NLM format requires a different
5398 way to write exports, so add a write_export field to the backend
5399 data (and set it to NULL for everything but the sparc).

5449 read_dynamic_relocs fields.
5450 * aout-target.h (MY(backend_data)): Initialize

5507 the DYNAMIC flag for the BFD.

5560 * ecofflink.c: Extensive changes to compress and merge debugging
5561 information, and to write some of out directly rather than saving

5565 sym_filepos as well.
5566 (ecoff_get_extr): Use ifdmap instead of ifdbase.

5632 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
5633 count it as a wrong format error, not a system call error, since
5634 the object file might simply be too small.
5636 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
5638 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

5641 * configure.in (nlm32_alpha_vec): Set target64 to true.
5643 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
5644 different, so there is no point to providing a generic one.
5645 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL

6535 * elfcode.h (elf_object_p): Rather than looking through an array
6536 of architectures, get the ELF EM_xxx code from the backend
6537 information. Let the generic ELF target match any EM_xxx code not
