3858 from call to _bfd_generic_link_add_one_symbol.
3859 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3860 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3861 instead of bitsize to add_to_set call back.
3862 (_bfd_generic_final_link): Account for link_order relocs when
3863 allocating space for relocations. Handle them in link_order loop.
3864 (_bfd_generic_reloc_link_order): New function.
3865 (_bfd_default_link_order): If a reloc_link_order is seen here,
3867 (_bfd_count_link_order_relocs): New function.
3868 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3869 argument from declaration.
3870 (_bfd_generic_reloc_link_order): Declare.
3871 (_bfd_count_link_order_relocs): Declare.
3872 * libbfd.h: Rebuilt.
3873 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3874 call to _bfd_generic_link_add_one_symbol.
3875 (NAME(aout,final_link)): Account for link_order relocs when
3876 allocating space for relocations. Handle them after handling all
3878 (aout_link_reloc_link_order): New function.
3879 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
3880 call to _bfd_generic_link_add_one_symbol.
3881 (ecoff_bfd_final_link): Account for link_order relocs when
3882 allocating space for relocations. Handle them in link_order loop.
3883 (ecoff_link_write_external): Set the storage class of a defined
3884 linker created symbol based on the section it is in. Correct
3885 bfd_link_hash_weak case to use .sc rather than .st.
3886 (ecoff_reloc_link_order): New function.
3887 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3889 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
3891 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
3894 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3895 bfd_zmalloc. Free a pointer, not a union.
3896 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3898 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3900 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3902 * som.c (bfd_section_from_som_symbol): Only to do the value
3903 comparison for function symbols within executables.
3905 * som.c (bfd_section_from_som_symbol): Renamed from
3906 som_section_from_subspace_index. Pass in a native SOM symbol.
3907 For executables, iterate through the sections to find out
3908 which contains the symbol's address rather than using the
3909 symbol_info field. (symbol_info has a different meaning for
3910 dynamicly linked executables.)
3912 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3915 * som.c (som_begin_writing): Fix braino (one call to align
3916 space/subspace data was done unconditionally rather than
3917 just for executables.)
3919 * som.c (som_begin_writing): Align text in all executables to
3920 make HPUX kernel happy. Fixes strip/objcopy for shared
3923 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3925 * som.c (som_begin_writing): Account for alignment needs of
3926 subspaces too when writing executables. Never request a negative
3927 bss size. Fixes some problems with demand paged executables,
3928 still having problems with pure executables and shared executables.
3930 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3932 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3933 bfd_zalloc for rawptr, because later on we may call free, not
3936 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3937 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3938 * cisco-core.c: New file.
3939 * Makefile.in: Change accordingly.
3940 * configure.in: Recognize cisco_core_vec.
3941 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3942 * targets.c: Add cisco_core_vec.
3943 * bfd-in2.h: Rebuilt.
3945 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3947 * som.h (som_copyable_section_data_struct): New structure
3948 containing all the private section information which needs
3949 to be copied from input section to output section during
3951 (som_section_data_struct): Remove several fields now in
3952 som_copyable_section_data_struct. Make the space and
3953 subspace dictionaries be pointers (to save space when
3954 only reading objects).
3956 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3957 some references changed. Allocate a copyable data stucture if
3958 none exists. Store info into the copyable data structure.
3959 (bfd_som_set_subsection_attributes): Likewise.
3960 (som_is_space, som_is_subspace, som_is_container): New functions.
3961 Use these instead of directly accessing private data.
3962 (som_prep_headers): Allocate space and subspace headers here.
3963 Fill in some fields in the space/subspace headers from the
3965 (som_bfd_copy_private_section_data): Only copy the stuff
3966 that we really need to make objcopy and strip work. Allocate
3967 the copy_data structure for the output bfd before copying.
3969 * som.h (struct som_exec_data): New structure to hold exec
3970 info that must be preserved when running objcopy/strip.
3971 (struct somdata): Add new "exec_data" field and accessor
3972 macro. Add some comments on how the various fields are used.
3973 (som_section_data_struct): Make is_space and is_subspace bitfields.
3974 Delete unused subspace_index. All references now use the
3975 target_index field within the section structure itself.
3977 * som.c (make_unique_section): Delete unused declaration.
3978 (som_bfd_copy_private_bfd_data): New function.
3979 (som_object_setup): Allocate space for and save exec information
3980 that needs to be copied during objcopy/strip.
3981 (som_mkobject): Do not allocate space for a file header here.
3982 It is not used when only reading SOM objects.
3983 (som_prep_headers): Allocate space for and attach a file header
3984 to the output bfd. For executables, use the saved system_id
3985 value rather than trying to guess the right value. Do not abort
3986 wwhen setting file_hdr->entry* for executables.
3987 (som_begin_writing): For executables, set the exec_entry and
3989 (som_copy_private_backend_section_data): Always return a value.
3991 * libhppa.h (PA_PAGESIZE): Define.
3993 * som.c (SOM_ALIGN): Define.
3994 (som_begin_writing): If writing an executable, initialize all
3995 fields in the exec header to zero. Update fields in the exec
3996 header as sizes of loadable subspaces are computed. Carefully
3997 preserve alignments when building executables. Actually write the
3998 exec after all the fields are filled in.
4000 * Better long-filename handling. Reads SOM ABI compliant extended
4001 names, but doesn't quite write compliant extended names yet.
4002 * som.c (som_slurp_extended_name_table): Delete function. The
4003 generic code will handle things correctly.
4004 (som_slurp_armap): Seek to the beginning of the next member.
4005 (normalize): New function.
4006 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4007 name table into account when computing the file offsets in the
4008 SOM dictionary. Make sure to align to an even boundary.
4009 (som_write_armap): Initialize the checksum to zero.
4010 (ar_maxchars): Fix. Opps.
4012 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4014 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4015 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4017 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4019 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4020 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4021 * bfd-in2.h: Regenerated.
4023 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4024 this was also named trad_unix_bfd_copy_private_bfd_data.
4026 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4028 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4029 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4030 returns NULL, it is not an error. It's possible that some of
4031 these checks are not necessary (because the size can never be
4032 zero), but putting in the checks is the conservative thing to do
4033 in light of the fact that some of these malloc calls replaced
4034 unchecked alloca calls, in which a zero argument would work fine.
4036 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4038 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4039 duplicate definition.
4040 (osf_core_bfd_is_local_label): Define.
4042 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4043 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4044 failure indication, it merely means there are no relocs.
4046 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4047 after NAME, since SunOS /bin/cc can't handle it.
4049 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4051 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4052 From sukes@glue.umd.edu (Tasuki Hirata).
4054 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4056 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4057 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4058 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4060 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4062 * som.c (som_prep_for_fixups): Detect section symbols based
4063 on either the lack of private data or the symbol flags. Do not
4064 munge section symbol names anymore -- they no longer confuse GDB.
4065 (som_begin_writing): Leave space for an exec header if writing
4067 (som_slurp_symbol_table): Recognize both forms of section symbol
4068 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4069 section symbols to be the name of the section they represent.
4070 Debugging symbols begin with "L$0\001", not just "L$".
4072 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4074 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4076 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4077 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4078 and bfd_is_local_label.
4080 * targets.c: Add new entries to the bfd_target structure.
4082 * bfd.c (bfd_copy_private_bfd_data): New definition.
4084 * section.c (bfd_copy_private_section_data): New definition.
4086 * syms.c (bfd_is_local_label): New definition.
4088 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4090 * libbfd.c (bfd_generic_is_local_label): New function.
4092 * *-core.c: Provide default definitions for new functions in
4093 the target vector which all point to bfd_false.
4095 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4096 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4097 Default new vectors for copying private backend data to bfd_true.
4098 Default new vector for determining if a symbol is a local label
4099 to bfd_generic_is_local_label.
4101 * som.c (som_bfd_copy_private_section_data): New function.
4102 (som_bfd_is_local_label): New function.
4103 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4105 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4107 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4109 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4111 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4114 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4115 Indent some of them to GNU standards.
4117 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4118 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4119 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4120 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4121 Update copyright years.
4123 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4125 * som.c (som_prep_for_fixups): A relocation involving the section
4126 symbol for the *ABS* section is really a relocation involving
4128 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4129 undefined symbols. Correctly distinguish between debugger symbols
4130 and section symbols.
4132 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4133 for spaces and subspaces.
4135 * som.c (som_bfd_count_ar_symbols): Fix typo.
4137 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4138 HAS_RELOC based on the object's magic number.
4139 (make_unique_section): Delete function. BFD and its users are
4140 prepared to handle multiple sections with the same name.
4141 (setup_sections): Allocate space on the BFD's obstack to hold
4142 section names. Use bfd_make_setion_anyway rather than the
4143 obsolete make_unique_section.
4144 (som_prep_headers): Choose the correct SOM magic number based
4146 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4148 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4150 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4151 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4152 * Makefile.in, configure.in: Corresponding changes.
4154 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4156 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4158 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4160 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4161 is always located at the start of the data section to allow
4162 recovery of the dynamic info from a stripped executable.
4163 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4166 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4168 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4169 cruft (like the #pragma alloca for AIX).
4170 In addition to that problem, the C alloca calls xmalloc, which
4171 means checking for being out of memory can't work right. The
4172 following changes remove all uses of alloca from BFD.
4173 * hosts/solaris2.h: Remove alloca cruft.
4174 * som.c: Replace alloca with a fixed size auto array.
4175 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4176 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4177 sunos.c: Replace alloca with malloc and appropriate error checking and
4179 * linker.c: Replace alloca with obstack_alloc.
4180 * libbfd.h: Rebuilt.
4182 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4184 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4187 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4189 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4190 Elf*_Off typedefs by their expansion, the typedefs have been
4191 removed from include/elf/internal.h.
4192 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4193 SHT_PROGBITS section.
4195 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4197 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4201 * configure.host: Recognize i[34]86-sequent-*.
4203 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4204 return from bfd_seek indicates an error.
4205 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4206 TRAD_CORE_STACK_OFFSET.
4207 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4208 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4210 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4212 * som.[ch]: Do not include libhppa.h in som.c, instead include
4215 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4216 include it in elf32-hppa.h.
4218 * som.c (log2): Return -1 on error rather than aborting.
4219 (setup_sections): Bubble up an error from log2.
4221 * Changes to make HP C compiler happy in both traditional
4223 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4225 (bfd_som_set_section_attributes): Use unsigned int rather than
4226 unsigned char to avoid GNU-C extensions.
4227 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4228 or failure rather than aborting on failure.
4230 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4232 (bfd_som_attach_aux_hdr): Add prototype.
4233 (hppa_som-gen_reloc_type): Likewise.
4235 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4236 (hppa_look_for_stubs_in_section): Do not return false on failure
4237 until rest of code is ready to handle it. Abort for now.
4239 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4241 * bfd-in2.h: Rebuilt.
4243 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
4245 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

4249 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4251 * config.bfd : Add i386-os9k.
4252 * config/i386-os9k.mt : Newly add os9k target makefile.
4254 * i386os9k.c : new file to handle os9k format bfd.
4255 * Makefile.in : Handle new file i386os9k.c
4256 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4257 * cache.c : Initialize cache_sentinel to 0.
4259 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4261 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4262 action in case where caller specified no argument relocation.
4263 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4264 right in the original relocation and the stub's relocation.
4266 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4267 unused symbols argument.
4269 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4270 than asymbol * for original target symbol. All callers changed.
4271 Set reloc->sym_ptr_ptr appropriately.
4272 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4273 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4274 argument. Use the output symbols when canonicalizing the relocs,
4275 creating them if necessary.
4277 * linker.c (_bfd_generic_link_output_symbols): Do not
4278 rebuild/clobber the output symbols if they already exist.
4280 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4282 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4283 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4284 * bfd-in2.h: Rebuilt.
4286 * srec.c (hex_value): Always set to a size of 256 bytes.
4287 (srec_init): Cosmetic changes.
4289 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4291 * elf32-hppa.c: Second half of major cleanup. More comments,
4292 PARAMize and staticize rest of functions. Delete unused
4293 functions. Delete unused/unnecessary arguments to some functions.
4294 Group static vars together. Abort for bad errors until we have
4295 error code propogation working. Work on spacing and indention.
4296 Add FIXMEs for unresolved problems. Use enums rather than
4297 #defines for lots of things. Merge two functions which build
4298 linker stubs into a single function (so they can easily share a
4299 ton of common code).
4301 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4303 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4304 avoid depending upon right shifts of signed numbers, and to
4305 correct handling of src_mask with lower bits zero.
4307 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4308 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

5227 The sparc (and possibly other?) NLM format requires a different
5228 way to write exports, so add a write_export field to the backend
5229 data (and set it to NULL for everything but the sparc).

6505 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
6506 MY_bfd_seclet_link): Define.
6507 (MY_bfd_reloc_type_lookup): Rename from
6508 MY_reloc_howto_type_lookup.
6509 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
6510 (MY(vec)): Use JUMP_TABLE rather than listing functions.
6511 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
6512 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
6513 terms of MY, because that causes a recusive invocation of CAT when
6514 expanded within JUMP_TABLE, and ANSI compilers don't expand
6516 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6517 MY_reloc_howto_type_lookup, and don't define in terms of MY.
6518 (MY_canonicalize_reloc): Don't define in terms of MY.
6519 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
6520 than listing functions.
