3785 For executables, iterate through the sections to find out
3786 which contains the symbol's address rather than using the
3787 symbol_info field. (symbol_info has a different meaning for
3788 dynamicly linked executables.)
3790 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3793 * som.c (som_begin_writing): Fix braino (one call to align

3826 containing all the private section information which needs
3827 to be copied from input section to output section during

3830 som_copyable_section_data_struct. Make the space and
3831 subspace dictionaries be pointers (to save space when
3832 only reading objects).
3834 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3835 some references changed. Allocate a copyable data stucture if
3836 none exists. Store info into the copyable data structure.
3837 (bfd_som_set_subsection_attributes): Likewise.
3838 (som_is_space, som_is_subspace, som_is_container): New functions.
3839 Use these instead of directly accessing private data.
3840 (som_prep_headers): Allocate space and subspace headers here.
3841 Fill in some fields in the space/subspace headers from the
3843 (som_bfd_copy_private_section_data): Only copy the stuff
3844 that we really need to make objcopy and strip work. Allocate
3845 the copy_data structure for the output bfd before copying.
3847 * som.h (struct som_exec_data): New structure to hold exec
3848 info that must be preserved when running objcopy/strip.
3849 (struct somdata): Add new "exec_data" field and accessor
3850 macro. Add some comments on how the various fields are used.
3851 (som_section_data_struct): Make is_space and is_subspace bitfields.
3852 Delete unused subspace_index. All references now use the
3853 target_index field within the section structure itself.
3855 * som.c (make_unique_section): Delete unused declaration.
3856 (som_bfd_copy_private_bfd_data): New function.
3857 (som_object_setup): Allocate space for and save exec information
3858 that needs to be copied during objcopy/strip.

3860 It is not used when only reading SOM objects.
3861 (som_prep_headers): Allocate space for and attach a file header
3862 to the output bfd. For executables, use the saved system_id
3863 value rather than trying to guess the right value. Do not abort
3864 wwhen setting file_hdr->entry* for executables.
3865 (som_begin_writing): For executables, set the exec_entry and
3867 (som_copy_private_backend_section_data): Always return a value.
3869 * libhppa.h (PA_PAGESIZE): Define.
3871 * som.c (SOM_ALIGN): Define.
3872 (som_begin_writing): If writing an executable, initialize all
3873 fields in the exec header to zero. Update fields in the exec
3874 header as sizes of loadable subspaces are computed. Carefully
3875 preserve alignments when building executables. Actually write the
3876 exec after all the fields are filled in.
3878 * Better long-filename handling. Reads SOM ABI compliant extended
3879 names, but doesn't quite write compliant extended names yet.
3880 * som.c (som_slurp_extended_name_table): Delete function. The
3881 generic code will handle things correctly.
3882 (som_slurp_armap): Seek to the beginning of the next member.
3883 (normalize): New function.
3884 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3885 name table into account when computing the file offsets in the
3886 SOM dictionary. Make sure to align to an even boundary.
3887 (som_write_armap): Initialize the checksum to zero.
3888 (ar_maxchars): Fix. Opps.
3890 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3892 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3893 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

3897 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3898 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3899 * bfd-in2.h: Regenerated.
3901 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3902 this was also named trad_unix_bfd_copy_private_bfd_data.
3904 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3906 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3907 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3908 returns NULL, it is not an error. It's possible that some of
3909 these checks are not necessary (because the size can never be
3910 zero), but putting in the checks is the conservative thing to do
3911 in light of the fact that some of these malloc calls replaced
3912 unchecked alloca calls, in which a zero argument would work fine.
3914 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3916 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3917 duplicate definition.

3920 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3921 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3922 failure indication, it merely means there are no relocs.
3924 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3925 after NAME, since SunOS /bin/cc can't handle it.
3927 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3929 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3930 From sukes@glue.umd.edu (Tasuki Hirata).
3932 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3934 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3935 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3936 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3938 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3940 * som.c (som_prep_for_fixups): Detect section symbols based
3941 on either the lack of private data or the symbol flags. Do not
3942 munge section symbol names anymore -- they no longer confuse GDB.
3943 (som_begin_writing): Leave space for an exec header if writing
3945 (som_slurp_symbol_table): Recognize both forms of section symbol
3946 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3947 section symbols to be the name of the section they represent.
3948 Debugging symbols begin with "L$0\001", not just "L$".
3950 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3955 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3956 and bfd_is_local_label.
3958 * targets.c: Add new entries to the bfd_target structure.

3971 the target vector which all point to bfd_false.
3973 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3974 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3975 Default new vectors for copying private backend data to bfd_true.
3976 Default new vector for determining if a symbol is a local label
3977 to bfd_generic_is_local_label.
3979 * som.c (som_bfd_copy_private_section_data): New function.
3980 (som_bfd_is_local_label): New function.
3981 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3983 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3985 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3987 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3989 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3992 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3993 Indent some of them to GNU standards.
3995 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3996 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3997 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3998 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3999 Update copyright years.
4001 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4003 * som.c (som_prep_for_fixups): A relocation involving the section
4004 symbol for the *ABS* section is really a relocation involving
4006 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4007 undefined symbols. Correctly distinguish between debugger symbols
4008 and section symbols.
4010 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4011 for spaces and subspaces.
4013 * som.c (som_bfd_count_ar_symbols): Fix typo.
4015 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4016 HAS_RELOC based on the object's magic number.
4017 (make_unique_section): Delete function. BFD and its users are
4018 prepared to handle multiple sections with the same name.
4019 (setup_sections): Allocate space on the BFD's obstack to hold
4020 section names. Use bfd_make_setion_anyway rather than the
4021 obsolete make_unique_section.
4022 (som_prep_headers): Choose the correct SOM magic number based
4024 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4044 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4046 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4047 cruft (like the #pragma alloca for AIX).
4048 In addition to that problem, the C alloca calls xmalloc, which
4049 means checking for being out of memory can't work right. The
4050 following changes remove all uses of alloca from BFD.
4051 * hosts/solaris2.h: Remove alloca cruft.
4052 * som.c: Replace alloca with a fixed size auto array.

4065 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4067 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4068 Elf*_Off typedefs by their expansion, the typedefs have been
4069 removed from include/elf/internal.h.
4070 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4071 SHT_PROGBITS section.
4073 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4084 TRAD_CORE_STACK_OFFSET.
4085 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4086 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

4090 * som.[ch]: Do not include libhppa.h in som.c, instead include
4093 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4094 include it in elf32-hppa.h.
4096 * som.c (log2): Return -1 on error rather than aborting.
4097 (setup_sections): Bubble up an error from log2.
4099 * Changes to make HP C compiler happy in both traditional
4101 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4103 (bfd_som_set_section_attributes): Use unsigned int rather than
4104 unsigned char to avoid GNU-C extensions.
4105 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4106 or failure rather than aborting on failure.
4108 * som.h (bfd_som_set_section_attributes): Fix prototype to match

4149 Set reloc->sym_ptr_ptr appropriately.
4150 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4151 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4152 argument. Use the output symbols when canonicalizing the relocs,
4153 creating them if necessary.
4155 * linker.c (_bfd_generic_link_output_symbols): Do not
4156 rebuild/clobber the output symbols if they already exist.
4158 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4160 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4174 Add FIXMEs for unresolved problems. Use enums rather than
4175 #defines for lots of things. Merge two functions which build
4176 linker stubs into a single function (so they can easily share a
4177 ton of common code).
4179 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4181 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4182 avoid depending upon right shifts of signed numbers, and to
4183 correct handling of src_mask with lower bits zero.

4215 (elf_hppa_final_processing): Add extern decl.
4217 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4218 comments. PARAMize some static functions. Delete unused functions.

4222 each case separately. Abort for bad errors until we get error
4223 code propogation working. Work on spacing and indention problems.
4224 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4225 COMPLEX relocation support (it's never used anyway).
4226 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4227 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4228 (elf_hppa_tc_make_sections): Likewise.

4269 * elfcode.h (alloca): Delete declaration.
4271 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4272 number rather than HP9000S800_ID. Note som.c is careful
4273 to make sure CPU_PA_RISC1_0 is always defined.
4275 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
4277 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

4815 * srec.c (srec_write_record): Put CONST keyword for "src" before
4816 "unsigned", some compilers don't like it after "unsigned".
4817 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

4889 _bfd_generic_link_write_global_symbol): Don't require that all

4935 (only testing for m68k and vax at the moment); do verify that the
4936 preprocessor didn't trash the arch name inside the string version.

4967 bfd_som_set_subsection_attributes): Change parameters from char
4968 to int. Following a prototype with an old-style function definition

5075 use get_value to get the symbol value and check for undefined
5077 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5078 undefined, look it up in the linker hash table.
5080 * aoutx.h (translate_symbol_table): The string index 0 has a

5105 The sparc (and possibly other?) NLM format requires a different
5106 way to write exports, so add a write_export field to the backend
5107 data (and set it to NULL for everything but the sparc).

5157 read_dynamic_relocs fields.
5158 * aout-target.h (MY(backend_data)): Initialize
