3448 get_symtab_upper_bound, bfd_canonicalize_symtab,
3449 bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc. They now
3450 return long instead of unsigned int, and use -1 to indicate an

3864 bss size. Fixes some problems with demand paged executables,
3865 still having problems with pure executables and shared executables.
3867 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3869 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3870 bfd_zalloc for rawptr, because later on we may call free, not
3873 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3874 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3875 * cisco-core.c: New file.
3876 * Makefile.in: Change accordingly.
3877 * configure.in: Recognize cisco_core_vec.
3878 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3879 * targets.c: Add cisco_core_vec.
3880 * bfd-in2.h: Rebuilt.
3882 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3884 * som.h (som_copyable_section_data_struct): New structure
3885 containing all the private section information which needs
3886 to be copied from input section to output section during
3888 (som_section_data_struct): Remove several fields now in
3889 som_copyable_section_data_struct. Make the space and
3890 subspace dictionaries be pointers (to save space when
3891 only reading objects).
3893 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3894 some references changed. Allocate a copyable data stucture if
3895 none exists. Store info into the copyable data structure.
3896 (bfd_som_set_subsection_attributes): Likewise.
3897 (som_is_space, som_is_subspace, som_is_container): New functions.
3898 Use these instead of directly accessing private data.
3899 (som_prep_headers): Allocate space and subspace headers here.
3900 Fill in some fields in the space/subspace headers from the
3902 (som_bfd_copy_private_section_data): Only copy the stuff
3903 that we really need to make objcopy and strip work. Allocate
3904 the copy_data structure for the output bfd before copying.
3906 * som.h (struct som_exec_data): New structure to hold exec
3907 info that must be preserved when running objcopy/strip.
3908 (struct somdata): Add new "exec_data" field and accessor
3909 macro. Add some comments on how the various fields are used.
3910 (som_section_data_struct): Make is_space and is_subspace bitfields.
3911 Delete unused subspace_index. All references now use the
3912 target_index field within the section structure itself.
3914 * som.c (make_unique_section): Delete unused declaration.
3915 (som_bfd_copy_private_bfd_data): New function.
3916 (som_object_setup): Allocate space for and save exec information
3917 that needs to be copied during objcopy/strip.
3918 (som_mkobject): Do not allocate space for a file header here.
3919 It is not used when only reading SOM objects.
3920 (som_prep_headers): Allocate space for and attach a file header
3921 to the output bfd. For executables, use the saved system_id
3922 value rather than trying to guess the right value. Do not abort
3923 wwhen setting file_hdr->entry* for executables.
3924 (som_begin_writing): For executables, set the exec_entry and
3926 (som_copy_private_backend_section_data): Always return a value.
3928 * libhppa.h (PA_PAGESIZE): Define.
3930 * som.c (SOM_ALIGN): Define.
3931 (som_begin_writing): If writing an executable, initialize all
3932 fields in the exec header to zero. Update fields in the exec
3933 header as sizes of loadable subspaces are computed. Carefully
3934 preserve alignments when building executables. Actually write the
3935 exec after all the fields are filled in.
3937 * Better long-filename handling. Reads SOM ABI compliant extended
3938 names, but doesn't quite write compliant extended names yet.
3939 * som.c (som_slurp_extended_name_table): Delete function. The
3940 generic code will handle things correctly.
3941 (som_slurp_armap): Seek to the beginning of the next member.
3942 (normalize): New function.
3943 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3944 name table into account when computing the file offsets in the
3945 SOM dictionary. Make sure to align to an even boundary.
3946 (som_write_armap): Initialize the checksum to zero.
3947 (ar_maxchars): Fix. Opps.
3949 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3951 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3952 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3954 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3956 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3957 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3958 * bfd-in2.h: Regenerated.
3960 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3961 this was also named trad_unix_bfd_copy_private_bfd_data.
3963 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3965 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3966 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3967 returns NULL, it is not an error. It's possible that some of
3968 these checks are not necessary (because the size can never be
3969 zero), but putting in the checks is the conservative thing to do
3970 in light of the fact that some of these malloc calls replaced
3971 unchecked alloca calls, in which a zero argument would work fine.
3973 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3975 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3976 duplicate definition.
3977 (osf_core_bfd_is_local_label): Define.
3979 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3980 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3981 failure indication, it merely means there are no relocs.
3983 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3984 after NAME, since SunOS /bin/cc can't handle it.
3986 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3988 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3989 From sukes@glue.umd.edu (Tasuki Hirata).
3991 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3993 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3994 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3995 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3997 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3999 * som.c (som_prep_for_fixups): Detect section symbols based
4000 on either the lack of private data or the symbol flags. Do not
4001 munge section symbol names anymore -- they no longer confuse GDB.
4002 (som_begin_writing): Leave space for an exec header if writing
4004 (som_slurp_symbol_table): Recognize both forms of section symbol
4005 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4006 section symbols to be the name of the section they represent.
4007 Debugging symbols begin with "L$0\001", not just "L$".
4009 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4011 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4013 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4014 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4015 and bfd_is_local_label.
4017 * targets.c: Add new entries to the bfd_target structure.
4019 * bfd.c (bfd_copy_private_bfd_data): New definition.
4021 * section.c (bfd_copy_private_section_data): New definition.
4023 * syms.c (bfd_is_local_label): New definition.
4025 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4027 * libbfd.c (bfd_generic_is_local_label): New function.
4029 * *-core.c: Provide default definitions for new functions in
4030 the target vector which all point to bfd_false.
4032 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4033 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4034 Default new vectors for copying private backend data to bfd_true.
4035 Default new vector for determining if a symbol is a local label
4036 to bfd_generic_is_local_label.
4038 * som.c (som_bfd_copy_private_section_data): New function.
4039 (som_bfd_is_local_label): New function.
4040 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4042 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4044 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4046 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4048 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4051 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4052 Indent some of them to GNU standards.
4054 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4055 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4056 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4057 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4058 Update copyright years.
4060 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4062 * som.c (som_prep_for_fixups): A relocation involving the section
4063 symbol for the *ABS* section is really a relocation involving
4065 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4066 undefined symbols. Correctly distinguish between debugger symbols
4067 and section symbols.
4069 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4070 for spaces and subspaces.
4072 * som.c (som_bfd_count_ar_symbols): Fix typo.
4074 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4075 HAS_RELOC based on the object's magic number.
4076 (make_unique_section): Delete function. BFD and its users are
4077 prepared to handle multiple sections with the same name.
4078 (setup_sections): Allocate space on the BFD's obstack to hold
4079 section names. Use bfd_make_setion_anyway rather than the
4080 obsolete make_unique_section.
4081 (som_prep_headers): Choose the correct SOM magic number based
4083 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4085 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4087 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4088 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4089 * Makefile.in, configure.in: Corresponding changes.

4097 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4098 is always located at the start of the data section to allow
4099 recovery of the dynamic info from a stripped executable.
4100 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4103 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4105 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4106 cruft (like the #pragma alloca for AIX).
4107 In addition to that problem, the C alloca calls xmalloc, which
4108 means checking for being out of memory can't work right. The
4109 following changes remove all uses of alloca from BFD.
4110 * hosts/solaris2.h: Remove alloca cruft.
4111 * som.c: Replace alloca with a fixed size auto array.
4112 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4113 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4114 sunos.c: Replace alloca with malloc and appropriate error checking and
4116 * linker.c: Replace alloca with obstack_alloc.
4117 * libbfd.h: Rebuilt.
4119 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4121 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4124 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4126 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4127 Elf*_Off typedefs by their expansion, the typedefs have been
4128 removed from include/elf/internal.h.
4129 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4130 SHT_PROGBITS section.
4132 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4134 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4140 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4141 return from bfd_seek indicates an error.
4142 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4143 TRAD_CORE_STACK_OFFSET.
4144 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4145 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4147 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4149 * som.[ch]: Do not include libhppa.h in som.c, instead include
4152 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4153 include it in elf32-hppa.h.
4155 * som.c (log2): Return -1 on error rather than aborting.
4156 (setup_sections): Bubble up an error from log2.
4158 * Changes to make HP C compiler happy in both traditional
4160 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4162 (bfd_som_set_section_attributes): Use unsigned int rather than
4163 unsigned char to avoid GNU-C extensions.
4164 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4165 or failure rather than aborting on failure.
4167 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4169 (bfd_som_attach_aux_hdr): Add prototype.
4170 (hppa_som-gen_reloc_type): Likewise.
4172 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4173 (hppa_look_for_stubs_in_section): Do not return false on failure
4174 until rest of code is ready to handle it. Abort for now.

4199 action in case where caller specified no argument relocation.
4200 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4201 right in the original relocation and the stub's relocation.
4203 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4204 unused symbols argument.
4206 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4207 than asymbol * for original target symbol. All callers changed.
4208 Set reloc->sym_ptr_ptr appropriately.
4209 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4210 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4211 argument. Use the output symbols when canonicalizing the relocs,
4212 creating them if necessary.
4214 * linker.c (_bfd_generic_link_output_symbols): Do not
4215 rebuild/clobber the output symbols if they already exist.
4217 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4219 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4220 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4221 * bfd-in2.h: Rebuilt.
4223 * srec.c (hex_value): Always set to a size of 256 bytes.
4224 (srec_init): Cosmetic changes.
4226 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4228 * elf32-hppa.c: Second half of major cleanup. More comments,
4229 PARAMize and staticize rest of functions. Delete unused
4230 functions. Delete unused/unnecessary arguments to some functions.
4231 Group static vars together. Abort for bad errors until we have
4232 error code propogation working. Work on spacing and indention.
4233 Add FIXMEs for unresolved problems. Use enums rather than
4234 #defines for lots of things. Merge two functions which build
4235 linker stubs into a single function (so they can easily share a
4236 ton of common code).
4238 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4240 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4241 avoid depending upon right shifts of signed numbers, and to
4242 correct handling of src_mask with lower bits zero.
4244 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

4270 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4272 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4273 (elf_hppa_tc_make_sections): Likewise.
4274 (elf_hppa_final_processing): Add extern decl.
4276 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4277 comments. PARAMize some static functions. Delete unused functions.
4278 Delete unused/unnecessary arguments to many functions. Group
4279 static vars together. Collapse common case statements together
4280 in many places. Use default case when possible instead of listing
4281 each case separately. Abort for bad errors until we get error
4282 code propogation working. Work on spacing and indention problems.
4283 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4284 COMPLEX relocation support (it's never used anyway).
4285 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4286 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4287 (elf_hppa_tc_make_sections): Likewise.
4289 * format.c (bfd_check_format_matches): Initialize matching_vector
4290 to keep gcc -Wall quiet.

4300 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
4302 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5134 use get_value to get the symbol value and check for undefined
5136 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5137 undefined, look it up in the linker hash table.
5139 * aoutx.h (translate_symbol_table): The string index 0 has a

5164 The sparc (and possibly other?) NLM format requires a different
5165 way to write exports, so add a write_export field to the backend
5166 data (and set it to NULL for everything but the sparc).
