3878 add_symbls entry point.
3880 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3881 counting relocs. Set SEC_RELOC flag for any section which has

3886 * linker.c (_bfd_generic_link_add_symbols): Just call
3887 generic_link_add_symbols.
3888 (_bfd_generic_link_add_symbols_collect): New function, like
3889 _bfd_generic_link_add_symbols but also collect constructors and
3890 destructors by name as collect2 does.
3891 (generic_link_add_symbols): New function, like old
3892 _bfd_generic_link_add_symbols but with collect argument.
3893 (generic_link_add_object_symbols): Take collect argument.

3905 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3906 for first character in an extended name.
3907 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3908 "//" as the name of the special archive member holding the
3909 extended name table.
3911 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3913 Support for link_order types which generate relocs in order to
3914 support -Ur in the linker.
3915 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3916 from call to _bfd_generic_link_add_one_symbol.
3917 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3918 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3919 instead of bitsize to add_to_set call back.
3920 (_bfd_generic_final_link): Account for link_order relocs when
3921 allocating space for relocations. Handle them in link_order loop.
3922 (_bfd_generic_reloc_link_order): New function.
3923 (_bfd_default_link_order): If a reloc_link_order is seen here,
3925 (_bfd_count_link_order_relocs): New function.
3926 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3927 argument from declaration.
3928 (_bfd_generic_reloc_link_order): Declare.
3929 (_bfd_count_link_order_relocs): Declare.
3930 * libbfd.h: Rebuilt.
3931 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3932 call to _bfd_generic_link_add_one_symbol.
3933 (NAME(aout,final_link)): Account for link_order relocs when

3938 call to _bfd_generic_link_add_one_symbol.
3939 (ecoff_bfd_final_link): Account for link_order relocs when
3940 allocating space for relocations. Handle them in link_order loop.
3941 (ecoff_link_write_external): Set the storage class of a defined
3942 linker created symbol based on the section it is in. Correct
3943 bfd_link_hash_weak case to use .sc rather than .st.
3944 (ecoff_reloc_link_order): New function.
3945 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3947 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3952 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3953 bfd_zmalloc. Free a pointer, not a union.
3954 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3956 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3958 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3960 * som.c (bfd_section_from_som_symbol): Only to do the value
3961 comparison for function symbols within executables.
3963 * som.c (bfd_section_from_som_symbol): Renamed from
3964 som_section_from_subspace_index. Pass in a native SOM symbol.
3965 For executables, iterate through the sections to find out
3966 which contains the symbol's address rather than using the
3967 symbol_info field. (symbol_info has a different meaning for
3968 dynamicly linked executables.)
3970 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3973 * som.c (som_begin_writing): Fix braino (one call to align
3974 space/subspace data was done unconditionally rather than
3975 just for executables.)
3977 * som.c (som_begin_writing): Align text in all executables to
3978 make HPUX kernel happy. Fixes strip/objcopy for shared
3981 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3983 * som.c (som_begin_writing): Account for alignment needs of
3984 subspaces too when writing executables. Never request a negative
3985 bss size. Fixes some problems with demand paged executables,
3986 still having problems with pure executables and shared executables.
3988 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3990 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3991 bfd_zalloc for rawptr, because later on we may call free, not
3994 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3995 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3996 * cisco-core.c: New file.
3997 * Makefile.in: Change accordingly.
3998 * configure.in: Recognize cisco_core_vec.
3999 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4000 * targets.c: Add cisco_core_vec.
4001 * bfd-in2.h: Rebuilt.
4003 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4005 * som.h (som_copyable_section_data_struct): New structure
4006 containing all the private section information which needs
4007 to be copied from input section to output section during
4009 (som_section_data_struct): Remove several fields now in
4010 som_copyable_section_data_struct. Make the space and
4011 subspace dictionaries be pointers (to save space when
4012 only reading objects).
4014 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4015 some references changed. Allocate a copyable data stucture if
4016 none exists. Store info into the copyable data structure.
4017 (bfd_som_set_subsection_attributes): Likewise.
4018 (som_is_space, som_is_subspace, som_is_container): New functions.
4019 Use these instead of directly accessing private data.
4020 (som_prep_headers): Allocate space and subspace headers here.
4021 Fill in some fields in the space/subspace headers from the
4023 (som_bfd_copy_private_section_data): Only copy the stuff
4024 that we really need to make objcopy and strip work. Allocate
4025 the copy_data structure for the output bfd before copying.
4027 * som.h (struct som_exec_data): New structure to hold exec
4028 info that must be preserved when running objcopy/strip.
4029 (struct somdata): Add new "exec_data" field and accessor
4030 macro. Add some comments on how the various fields are used.
4031 (som_section_data_struct): Make is_space and is_subspace bitfields.
4032 Delete unused subspace_index. All references now use the
4033 target_index field within the section structure itself.
4035 * som.c (make_unique_section): Delete unused declaration.
4036 (som_bfd_copy_private_bfd_data): New function.
4037 (som_object_setup): Allocate space for and save exec information
4038 that needs to be copied during objcopy/strip.
4039 (som_mkobject): Do not allocate space for a file header here.
4040 It is not used when only reading SOM objects.
4041 (som_prep_headers): Allocate space for and attach a file header
4042 to the output bfd. For executables, use the saved system_id
4043 value rather than trying to guess the right value. Do not abort
4044 wwhen setting file_hdr->entry* for executables.
4045 (som_begin_writing): For executables, set the exec_entry and
4047 (som_copy_private_backend_section_data): Always return a value.
4049 * libhppa.h (PA_PAGESIZE): Define.
4051 * som.c (SOM_ALIGN): Define.
4052 (som_begin_writing): If writing an executable, initialize all
4053 fields in the exec header to zero. Update fields in the exec
4054 header as sizes of loadable subspaces are computed. Carefully
4055 preserve alignments when building executables. Actually write the
4056 exec after all the fields are filled in.
4058 * Better long-filename handling. Reads SOM ABI compliant extended
4059 names, but doesn't quite write compliant extended names yet.
4060 * som.c (som_slurp_extended_name_table): Delete function. The
4061 generic code will handle things correctly.
4062 (som_slurp_armap): Seek to the beginning of the next member.
4063 (normalize): New function.
4064 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4065 name table into account when computing the file offsets in the
4066 SOM dictionary. Make sure to align to an even boundary.
4067 (som_write_armap): Initialize the checksum to zero.
4068 (ar_maxchars): Fix. Opps.
4070 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4072 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4073 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4075 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4077 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4078 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4079 * bfd-in2.h: Regenerated.
4081 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4082 this was also named trad_unix_bfd_copy_private_bfd_data.
4084 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4086 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4087 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4088 returns NULL, it is not an error. It's possible that some of
4089 these checks are not necessary (because the size can never be
4090 zero), but putting in the checks is the conservative thing to do
4091 in light of the fact that some of these malloc calls replaced
4092 unchecked alloca calls, in which a zero argument would work fine.
4094 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4096 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4097 duplicate definition.
4098 (osf_core_bfd_is_local_label): Define.
4100 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4101 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4102 failure indication, it merely means there are no relocs.
4104 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4105 after NAME, since SunOS /bin/cc can't handle it.
4107 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4109 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4110 From sukes@glue.umd.edu (Tasuki Hirata).
4112 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4114 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4115 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4116 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4118 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4120 * som.c (som_prep_for_fixups): Detect section symbols based
4121 on either the lack of private data or the symbol flags. Do not
4122 munge section symbol names anymore -- they no longer confuse GDB.
4123 (som_begin_writing): Leave space for an exec header if writing
4125 (som_slurp_symbol_table): Recognize both forms of section symbol
4126 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4127 section symbols to be the name of the section they represent.
4128 Debugging symbols begin with "L$0\001", not just "L$".
4130 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4132 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4134 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4135 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4136 and bfd_is_local_label.
4138 * targets.c: Add new entries to the bfd_target structure.
4140 * bfd.c (bfd_copy_private_bfd_data): New definition.
4142 * section.c (bfd_copy_private_section_data): New definition.
4144 * syms.c (bfd_is_local_label): New definition.
4146 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4148 * libbfd.c (bfd_generic_is_local_label): New function.
4150 * *-core.c: Provide default definitions for new functions in
4151 the target vector which all point to bfd_false.
4153 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4154 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4155 Default new vectors for copying private backend data to bfd_true.
4156 Default new vector for determining if a symbol is a local label
4157 to bfd_generic_is_local_label.
4159 * som.c (som_bfd_copy_private_section_data): New function.
4160 (som_bfd_is_local_label): New function.
4161 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4163 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4165 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4167 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4169 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4172 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4173 Indent some of them to GNU standards.
4175 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4176 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4177 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4178 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4179 Update copyright years.
4181 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4183 * som.c (som_prep_for_fixups): A relocation involving the section
4184 symbol for the *ABS* section is really a relocation involving
4186 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4187 undefined symbols. Correctly distinguish between debugger symbols
4188 and section symbols.
4190 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4191 for spaces and subspaces.
4193 * som.c (som_bfd_count_ar_symbols): Fix typo.
4195 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4196 HAS_RELOC based on the object's magic number.
4197 (make_unique_section): Delete function. BFD and its users are
4198 prepared to handle multiple sections with the same name.
4199 (setup_sections): Allocate space on the BFD's obstack to hold
4200 section names. Use bfd_make_setion_anyway rather than the
4201 obsolete make_unique_section.
4202 (som_prep_headers): Choose the correct SOM magic number based
4204 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4206 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4208 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4218 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4219 is always located at the start of the data section to allow
4220 recovery of the dynamic info from a stripped executable.
4221 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4224 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4226 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4227 cruft (like the #pragma alloca for AIX).
4228 In addition to that problem, the C alloca calls xmalloc, which
4229 means checking for being out of memory can't work right. The
4230 following changes remove all uses of alloca from BFD.
4231 * hosts/solaris2.h: Remove alloca cruft.
4232 * som.c: Replace alloca with a fixed size auto array.

4237 * linker.c: Replace alloca with obstack_alloc.
4238 * libbfd.h: Rebuilt.
4240 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4242 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4245 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4247 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4248 Elf*_Off typedefs by their expansion, the typedefs have been
4249 removed from include/elf/internal.h.
4250 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4251 SHT_PROGBITS section.
4253 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4255 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4259 * configure.host: Recognize i[34]86-sequent-*.
4261 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4262 return from bfd_seek indicates an error.
4263 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4264 TRAD_CORE_STACK_OFFSET.
4265 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4266 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4268 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4270 * som.[ch]: Do not include libhppa.h in som.c, instead include
4273 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4274 include it in elf32-hppa.h.
4276 * som.c (log2): Return -1 on error rather than aborting.
4277 (setup_sections): Bubble up an error from log2.
4279 * Changes to make HP C compiler happy in both traditional
4281 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4283 (bfd_som_set_section_attributes): Use unsigned int rather than
4284 unsigned char to avoid GNU-C extensions.
4285 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4286 or failure rather than aborting on failure.
4288 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4290 (bfd_som_attach_aux_hdr): Add prototype.
4291 (hppa_som-gen_reloc_type): Likewise.
4293 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4294 (hppa_look_for_stubs_in_section): Do not return false on failure
4295 until rest of code is ready to handle it. Abort for now.
4297 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4299 * bfd-in2.h: Rebuilt.
4301 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

4580 (b_out_relax_section): If a section contains no relocations, don't
4581 bother processing them.
4582 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5285 The sparc (and possibly other?) NLM format requires a different
5286 way to write exports, so add a write_export field to the backend
5287 data (and set it to NULL for everything but the sparc).

6572 expanded within JUMP_TABLE, and ANSI compilers don't expand
6574 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6575 MY_reloc_howto_type_lookup, and don't define in terms of MY.
