3861 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3863 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3865 * som.c (bfd_section_from_som_symbol): Only to do the value
3866 comparison for function symbols within executables.
3868 * som.c (bfd_section_from_som_symbol): Renamed from
3869 som_section_from_subspace_index. Pass in a native SOM symbol.
3870 For executables, iterate through the sections to find out
3871 which contains the symbol's address rather than using the
3872 symbol_info field. (symbol_info has a different meaning for
3873 dynamicly linked executables.)
3875 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3878 * som.c (som_begin_writing): Fix braino (one call to align
3879 space/subspace data was done unconditionally rather than
3880 just for executables.)
3882 * som.c (som_begin_writing): Align text in all executables to
3883 make HPUX kernel happy. Fixes strip/objcopy for shared
3886 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3888 * som.c (som_begin_writing): Account for alignment needs of
3889 subspaces too when writing executables. Never request a negative
3890 bss size. Fixes some problems with demand paged executables,
3891 still having problems with pure executables and shared executables.
3893 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3895 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3896 bfd_zalloc for rawptr, because later on we may call free, not
3899 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3900 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3901 * cisco-core.c: New file.
3902 * Makefile.in: Change accordingly.
3903 * configure.in: Recognize cisco_core_vec.
3904 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3905 * targets.c: Add cisco_core_vec.
3906 * bfd-in2.h: Rebuilt.
3908 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3910 * som.h (som_copyable_section_data_struct): New structure
3911 containing all the private section information which needs
3912 to be copied from input section to output section during
3914 (som_section_data_struct): Remove several fields now in
3915 som_copyable_section_data_struct. Make the space and
3916 subspace dictionaries be pointers (to save space when
3917 only reading objects).
3919 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3920 some references changed. Allocate a copyable data stucture if
3921 none exists. Store info into the copyable data structure.
3922 (bfd_som_set_subsection_attributes): Likewise.
3923 (som_is_space, som_is_subspace, som_is_container): New functions.
3924 Use these instead of directly accessing private data.
3925 (som_prep_headers): Allocate space and subspace headers here.
3926 Fill in some fields in the space/subspace headers from the
3928 (som_bfd_copy_private_section_data): Only copy the stuff
3929 that we really need to make objcopy and strip work. Allocate
3930 the copy_data structure for the output bfd before copying.
3932 * som.h (struct som_exec_data): New structure to hold exec
3933 info that must be preserved when running objcopy/strip.
3934 (struct somdata): Add new "exec_data" field and accessor
3935 macro. Add some comments on how the various fields are used.
3936 (som_section_data_struct): Make is_space and is_subspace bitfields.
3937 Delete unused subspace_index. All references now use the
3938 target_index field within the section structure itself.
3940 * som.c (make_unique_section): Delete unused declaration.
3941 (som_bfd_copy_private_bfd_data): New function.
3942 (som_object_setup): Allocate space for and save exec information
3943 that needs to be copied during objcopy/strip.
3944 (som_mkobject): Do not allocate space for a file header here.
3945 It is not used when only reading SOM objects.
3946 (som_prep_headers): Allocate space for and attach a file header
3947 to the output bfd. For executables, use the saved system_id
3948 value rather than trying to guess the right value. Do not abort
3949 wwhen setting file_hdr->entry* for executables.
3950 (som_begin_writing): For executables, set the exec_entry and
3952 (som_copy_private_backend_section_data): Always return a value.
3954 * libhppa.h (PA_PAGESIZE): Define.
3956 * som.c (SOM_ALIGN): Define.
3957 (som_begin_writing): If writing an executable, initialize all
3958 fields in the exec header to zero. Update fields in the exec
3959 header as sizes of loadable subspaces are computed. Carefully
3960 preserve alignments when building executables. Actually write the
3961 exec after all the fields are filled in.
3963 * Better long-filename handling. Reads SOM ABI compliant extended
3964 names, but doesn't quite write compliant extended names yet.
3965 * som.c (som_slurp_extended_name_table): Delete function. The
3966 generic code will handle things correctly.
3967 (som_slurp_armap): Seek to the beginning of the next member.
3968 (normalize): New function.
3969 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3970 name table into account when computing the file offsets in the
3971 SOM dictionary. Make sure to align to an even boundary.
3972 (som_write_armap): Initialize the checksum to zero.
3973 (ar_maxchars): Fix. Opps.
3975 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3977 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3978 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3980 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3982 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3983 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3984 * bfd-in2.h: Regenerated.
3986 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3987 this was also named trad_unix_bfd_copy_private_bfd_data.
3989 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3991 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3992 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3993 returns NULL, it is not an error. It's possible that some of
3994 these checks are not necessary (because the size can never be
3995 zero), but putting in the checks is the conservative thing to do
3996 in light of the fact that some of these malloc calls replaced
3997 unchecked alloca calls, in which a zero argument would work fine.
3999 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4001 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4002 duplicate definition.
4003 (osf_core_bfd_is_local_label): Define.
4005 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4006 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4007 failure indication, it merely means there are no relocs.
4009 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4010 after NAME, since SunOS /bin/cc can't handle it.
4012 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4014 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4015 From sukes@glue.umd.edu (Tasuki Hirata).
4017 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4019 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4020 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4021 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4023 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4025 * som.c (som_prep_for_fixups): Detect section symbols based
4026 on either the lack of private data or the symbol flags. Do not
4027 munge section symbol names anymore -- they no longer confuse GDB.
4028 (som_begin_writing): Leave space for an exec header if writing
4030 (som_slurp_symbol_table): Recognize both forms of section symbol
4031 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4032 section symbols to be the name of the section they represent.
4033 Debugging symbols begin with "L$0\001", not just "L$".
4035 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4037 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4039 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4040 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4041 and bfd_is_local_label.
4043 * targets.c: Add new entries to the bfd_target structure.
4045 * bfd.c (bfd_copy_private_bfd_data): New definition.
4047 * section.c (bfd_copy_private_section_data): New definition.
4049 * syms.c (bfd_is_local_label): New definition.
4051 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4053 * libbfd.c (bfd_generic_is_local_label): New function.
4055 * *-core.c: Provide default definitions for new functions in
4056 the target vector which all point to bfd_false.
4058 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4059 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4060 Default new vectors for copying private backend data to bfd_true.
4061 Default new vector for determining if a symbol is a local label
4062 to bfd_generic_is_local_label.
4064 * som.c (som_bfd_copy_private_section_data): New function.
4065 (som_bfd_is_local_label): New function.
4066 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4068 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4070 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4072 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4074 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4077 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4078 Indent some of them to GNU standards.
4080 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4081 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4082 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4083 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4084 Update copyright years.
4086 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4088 * som.c (som_prep_for_fixups): A relocation involving the section
4089 symbol for the *ABS* section is really a relocation involving
4091 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4092 undefined symbols. Correctly distinguish between debugger symbols
4093 and section symbols.
4095 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4096 for spaces and subspaces.
4098 * som.c (som_bfd_count_ar_symbols): Fix typo.
4100 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4101 HAS_RELOC based on the object's magic number.
4102 (make_unique_section): Delete function. BFD and its users are
4103 prepared to handle multiple sections with the same name.
4104 (setup_sections): Allocate space on the BFD's obstack to hold
4105 section names. Use bfd_make_setion_anyway rather than the
4106 obsolete make_unique_section.
4107 (som_prep_headers): Choose the correct SOM magic number based
4109 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4111 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4113 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4114 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4115 * Makefile.in, configure.in: Corresponding changes.
4117 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4119 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4121 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4123 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4124 is always located at the start of the data section to allow
4125 recovery of the dynamic info from a stripped executable.
4126 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4129 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4131 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4132 cruft (like the #pragma alloca for AIX).
4133 In addition to that problem, the C alloca calls xmalloc, which
4134 means checking for being out of memory can't work right. The
4135 following changes remove all uses of alloca from BFD.
4136 * hosts/solaris2.h: Remove alloca cruft.
4137 * som.c: Replace alloca with a fixed size auto array.
4138 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4139 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4140 sunos.c: Replace alloca with malloc and appropriate error checking and
4142 * linker.c: Replace alloca with obstack_alloc.
4143 * libbfd.h: Rebuilt.
4145 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4147 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4150 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4152 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4153 Elf*_Off typedefs by their expansion, the typedefs have been
4154 removed from include/elf/internal.h.
4155 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4156 SHT_PROGBITS section.
4158 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4160 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4164 * configure.host: Recognize i[34]86-sequent-*.
4166 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4167 return from bfd_seek indicates an error.
4168 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4169 TRAD_CORE_STACK_OFFSET.
4170 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4171 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4173 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4175 * som.[ch]: Do not include libhppa.h in som.c, instead include
4178 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4179 include it in elf32-hppa.h.
4181 * som.c (log2): Return -1 on error rather than aborting.
4182 (setup_sections): Bubble up an error from log2.
4184 * Changes to make HP C compiler happy in both traditional
4186 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4188 (bfd_som_set_section_attributes): Use unsigned int rather than
4189 unsigned char to avoid GNU-C extensions.
4190 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4191 or failure rather than aborting on failure.
4193 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4195 (bfd_som_attach_aux_hdr): Add prototype.
4196 (hppa_som-gen_reloc_type): Likewise.
4198 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4199 (hppa_look_for_stubs_in_section): Do not return false on failure
4200 until rest of code is ready to handle it. Abort for now.
4202 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4204 * bfd-in2.h: Rebuilt.
4206 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
4208 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

4212 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4214 * config.bfd : Add i386-os9k.
4215 * config/i386-os9k.mt : Newly add os9k target makefile.
4217 * i386os9k.c : new file to handle os9k format bfd.
4218 * Makefile.in : Handle new file i386os9k.c
4219 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4220 * cache.c : Initialize cache_sentinel to 0.

4224 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4225 action in case where caller specified no argument relocation.
4226 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4227 right in the original relocation and the stub's relocation.
4229 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4230 unused symbols argument.
4232 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4233 than asymbol * for original target symbol. All callers changed.
4234 Set reloc->sym_ptr_ptr appropriately.
4235 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4236 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4237 argument. Use the output symbols when canonicalizing the relocs,
4238 creating them if necessary.
4240 * linker.c (_bfd_generic_link_output_symbols): Do not
4241 rebuild/clobber the output symbols if they already exist.
4243 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4245 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4246 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4247 * bfd-in2.h: Rebuilt.
4249 * srec.c (hex_value): Always set to a size of 256 bytes.
4250 (srec_init): Cosmetic changes.
4252 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4254 * elf32-hppa.c: Second half of major cleanup. More comments,
4255 PARAMize and staticize rest of functions. Delete unused
4256 functions. Delete unused/unnecessary arguments to some functions.
4257 Group static vars together. Abort for bad errors until we have
4258 error code propogation working. Work on spacing and indention.
4259 Add FIXMEs for unresolved problems. Use enums rather than
4260 #defines for lots of things. Merge two functions which build
4261 linker stubs into a single function (so they can easily share a
4262 ton of common code).
4264 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4266 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4267 avoid depending upon right shifts of signed numbers, and to
4268 correct handling of src_mask with lower bits zero.
4270 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4271 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

4278 (write_shdrs_and_ehdr): Make count unsigned.
4279 (assign_file_positions_for_relocs): Make i unsigned.
4280 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
4281 (section_from_elf_index): Make index argument unsigned.
4283 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
4285 * elfcode.h: Don't include assert.h.
4286 (swap_out_syms): Use BFD_ASSERT rather than assert.
4288 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
4291 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
4294 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4296 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4298 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4299 (elf_hppa_tc_make_sections): Likewise.
4300 (elf_hppa_final_processing): Add extern decl.
4302 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4303 comments. PARAMize some static functions. Delete unused functions.
4304 Delete unused/unnecessary arguments to many functions. Group
4305 static vars together. Collapse common case statements together
4306 in many places. Use default case when possible instead of listing
4307 each case separately. Abort for bad errors until we get error
4308 code propogation working. Work on spacing and indention problems.
4309 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4310 COMPLEX relocation support (it's never used anyway).
4311 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4312 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4313 (elf_hppa_tc_make_sections): Likewise.
4315 * format.c (bfd_check_format_matches): Initialize matching_vector

5157 (get_value): If the symbol is undefined, look it up in the linker
5159 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
5160 use get_value to get the symbol value and check for undefined
5162 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5163 undefined, look it up in the linker hash table.
5165 * aoutx.h (translate_symbol_table): The string index 0 has a

5190 The sparc (and possibly other?) NLM format requires a different
5191 way to write exports, so add a write_export field to the backend
5192 data (and set it to NULL for everything but the sparc).
