3872 som_copyable_section_data_struct. Make the space and
3873 subspace dictionaries be pointers (to save space when
3874 only reading objects).
3876 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3877 some references changed. Allocate a copyable data stucture if
3878 none exists. Store info into the copyable data structure.
3879 (bfd_som_set_subsection_attributes): Likewise.
3880 (som_is_space, som_is_subspace, som_is_container): New functions.
3881 Use these instead of directly accessing private data.
3882 (som_prep_headers): Allocate space and subspace headers here.
3883 Fill in some fields in the space/subspace headers from the
3885 (som_bfd_copy_private_section_data): Only copy the stuff
3886 that we really need to make objcopy and strip work. Allocate
3887 the copy_data structure for the output bfd before copying.
3889 * som.h (struct som_exec_data): New structure to hold exec
3890 info that must be preserved when running objcopy/strip.
3891 (struct somdata): Add new "exec_data" field and accessor
3892 macro. Add some comments on how the various fields are used.
3893 (som_section_data_struct): Make is_space and is_subspace bitfields.
3894 Delete unused subspace_index. All references now use the
3895 target_index field within the section structure itself.
3897 * som.c (make_unique_section): Delete unused declaration.
3898 (som_bfd_copy_private_bfd_data): New function.
3899 (som_object_setup): Allocate space for and save exec information
3900 that needs to be copied during objcopy/strip.
3901 (som_mkobject): Do not allocate space for a file header here.
3902 It is not used when only reading SOM objects.
3903 (som_prep_headers): Allocate space for and attach a file header
3904 to the output bfd. For executables, use the saved system_id
3905 value rather than trying to guess the right value. Do not abort
3906 wwhen setting file_hdr->entry* for executables.
3907 (som_begin_writing): For executables, set the exec_entry and
3909 (som_copy_private_backend_section_data): Always return a value.
3911 * libhppa.h (PA_PAGESIZE): Define.
3913 * som.c (SOM_ALIGN): Define.
3914 (som_begin_writing): If writing an executable, initialize all
3915 fields in the exec header to zero. Update fields in the exec
3916 header as sizes of loadable subspaces are computed. Carefully
3917 preserve alignments when building executables. Actually write the
3918 exec after all the fields are filled in.
3920 * Better long-filename handling. Reads SOM ABI compliant extended
3921 names, but doesn't quite write compliant extended names yet.
3922 * som.c (som_slurp_extended_name_table): Delete function. The
3923 generic code will handle things correctly.
3924 (som_slurp_armap): Seek to the beginning of the next member.
3925 (normalize): New function.
3926 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3927 name table into account when computing the file offsets in the
3928 SOM dictionary. Make sure to align to an even boundary.
3929 (som_write_armap): Initialize the checksum to zero.
3930 (ar_maxchars): Fix. Opps.
3932 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3934 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3935 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3937 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3939 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3940 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3941 * bfd-in2.h: Regenerated.
3943 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3944 this was also named trad_unix_bfd_copy_private_bfd_data.
3946 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3948 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3949 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3950 returns NULL, it is not an error. It's possible that some of
3951 these checks are not necessary (because the size can never be
3952 zero), but putting in the checks is the conservative thing to do
3953 in light of the fact that some of these malloc calls replaced
3954 unchecked alloca calls, in which a zero argument would work fine.
3956 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3958 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3959 duplicate definition.
3960 (osf_core_bfd_is_local_label): Define.
3962 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3963 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3964 failure indication, it merely means there are no relocs.
3966 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3967 after NAME, since SunOS /bin/cc can't handle it.
3969 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3971 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3972 From sukes@glue.umd.edu (Tasuki Hirata).
3974 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3976 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3977 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3978 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3980 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3982 * som.c (som_prep_for_fixups): Detect section symbols based
3983 on either the lack of private data or the symbol flags. Do not
3984 munge section symbol names anymore -- they no longer confuse GDB.
3985 (som_begin_writing): Leave space for an exec header if writing
3987 (som_slurp_symbol_table): Recognize both forms of section symbol
3988 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3989 section symbols to be the name of the section they represent.
3990 Debugging symbols begin with "L$0\001", not just "L$".
3992 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3994 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3996 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3997 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3998 and bfd_is_local_label.
4000 * targets.c: Add new entries to the bfd_target structure.
4002 * bfd.c (bfd_copy_private_bfd_data): New definition.

4010 * libbfd.c (bfd_generic_is_local_label): New function.
4012 * *-core.c: Provide default definitions for new functions in
4013 the target vector which all point to bfd_false.
4015 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4016 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4017 Default new vectors for copying private backend data to bfd_true.
4018 Default new vector for determining if a symbol is a local label
4019 to bfd_generic_is_local_label.
4021 * som.c (som_bfd_copy_private_section_data): New function.
4022 (som_bfd_is_local_label): New function.
4023 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4025 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4027 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4029 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4031 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4034 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4035 Indent some of them to GNU standards.
4037 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4038 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4039 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4040 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4041 Update copyright years.
4043 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4045 * som.c (som_prep_for_fixups): A relocation involving the section
4046 symbol for the *ABS* section is really a relocation involving
4048 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4049 undefined symbols. Correctly distinguish between debugger symbols
4050 and section symbols.
4052 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4053 for spaces and subspaces.
4055 * som.c (som_bfd_count_ar_symbols): Fix typo.
4057 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4058 HAS_RELOC based on the object's magic number.
4059 (make_unique_section): Delete function. BFD and its users are
4060 prepared to handle multiple sections with the same name.
4061 (setup_sections): Allocate space on the BFD's obstack to hold
4062 section names. Use bfd_make_setion_anyway rather than the
4063 obsolete make_unique_section.
4064 (som_prep_headers): Choose the correct SOM magic number based
4066 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4080 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4081 is always located at the start of the data section to allow
4082 recovery of the dynamic info from a stripped executable.
4083 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4086 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4088 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4089 cruft (like the #pragma alloca for AIX).
4090 In addition to that problem, the C alloca calls xmalloc, which
4091 means checking for being out of memory can't work right. The
4092 following changes remove all uses of alloca from BFD.
4093 * hosts/solaris2.h: Remove alloca cruft.
4094 * som.c: Replace alloca with a fixed size auto array.
4095 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

4097 sunos.c: Replace alloca with malloc and appropriate error checking and
4099 * linker.c: Replace alloca with obstack_alloc.
4100 * libbfd.h: Rebuilt.
4102 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4104 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4107 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4109 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4110 Elf*_Off typedefs by their expansion, the typedefs have been
4111 removed from include/elf/internal.h.
4112 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4113 SHT_PROGBITS section.
4115 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4117 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4123 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4124 return from bfd_seek indicates an error.
4125 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4126 TRAD_CORE_STACK_OFFSET.
4127 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4128 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4130 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4132 * som.[ch]: Do not include libhppa.h in som.c, instead include
4135 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4136 include it in elf32-hppa.h.
4138 * som.c (log2): Return -1 on error rather than aborting.
4139 (setup_sections): Bubble up an error from log2.
4141 * Changes to make HP C compiler happy in both traditional
4143 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4145 (bfd_som_set_section_attributes): Use unsigned int rather than
4146 unsigned char to avoid GNU-C extensions.
4147 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4148 or failure rather than aborting on failure.
4150 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4152 (bfd_som_attach_aux_hdr): Add prototype.
4153 (hppa_som-gen_reloc_type): Likewise.
4155 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4156 (hppa_look_for_stubs_in_section): Do not return false on failure
4157 until rest of code is ready to handle it. Abort for now.

4182 action in case where caller specified no argument relocation.
4183 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4184 right in the original relocation and the stub's relocation.

4187 unused symbols argument.
4189 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

4191 Set reloc->sym_ptr_ptr appropriately.
4192 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4193 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4194 argument. Use the output symbols when canonicalizing the relocs,
4195 creating them if necessary.
4197 * linker.c (_bfd_generic_link_output_symbols): Do not
4198 rebuild/clobber the output symbols if they already exist.
4200 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4202 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4212 PARAMize and staticize rest of functions. Delete unused
4213 functions. Delete unused/unnecessary arguments to some functions.

4215 error code propogation working. Work on spacing and indention.
4216 Add FIXMEs for unresolved problems. Use enums rather than
4217 #defines for lots of things. Merge two functions which build
4218 linker stubs into a single function (so they can easily share a
4219 ton of common code).
4221 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4223 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4224 avoid depending upon right shifts of signed numbers, and to
4225 correct handling of src_mask with lower bits zero.

4255 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4256 (elf_hppa_tc_make_sections): Likewise.
4257 (elf_hppa_final_processing): Add extern decl.
4259 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4260 comments. PARAMize some static functions. Delete unused functions.
4261 Delete unused/unnecessary arguments to many functions. Group
4262 static vars together. Collapse common case statements together
4263 in many places. Use default case when possible instead of listing
4264 each case separately. Abort for bad errors until we get error
4265 code propogation working. Work on spacing and indention problems.
4266 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4267 COMPLEX relocation support (it's never used anyway).
4268 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4269 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4270 (elf_hppa_tc_make_sections): Likewise.

4283 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
4285 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4311 * elfcode.h (alloca): Delete declaration.
4313 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4314 number rather than HP9000S800_ID. Note som.c is careful
4315 to make sure CPU_PA_RISC1_0 is always defined.
4317 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
4319 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5009 bfd_som_set_subsection_attributes): Change parameters from char
5010 to int. Following a prototype with an old-style function definition

5117 use get_value to get the symbol value and check for undefined
5119 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5120 undefined, look it up in the linker hash table.
5122 * aoutx.h (translate_symbol_table): The string index 0 has a

5147 The sparc (and possibly other?) NLM format requires a different
5148 way to write exports, so add a write_export field to the backend
5149 data (and set it to NULL for everything but the sparc).

5199 read_dynamic_relocs fields.
5200 * aout-target.h (MY(backend_data)): Initialize
