2112 an empty .plt section.
2113 (elf32_sparc_relocate_section): For a GOT reloc against a global
2114 symbol when no dynamic object was seen, initialize the contents of
2115 the .got section. For a GOT reloc against a local symbol, only

2117 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2118 create a PLT entry as a R_SPARC_WDISP30 reloc.

5686 (_bfd_write_archive_contents): If ar_padchar == '/', then use
5687 "//" as the name of the special archive member holding the
5688 extended name table.
5690 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5692 Support for link_order types which generate relocs in order to
5693 support -Ur in the linker.
5694 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5695 from call to _bfd_generic_link_add_one_symbol.
5696 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5697 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5698 instead of bitsize to add_to_set call back.
5699 (_bfd_generic_final_link): Account for link_order relocs when
5700 allocating space for relocations. Handle them in link_order loop.
5701 (_bfd_generic_reloc_link_order): New function.
5702 (_bfd_default_link_order): If a reloc_link_order is seen here,
5704 (_bfd_count_link_order_relocs): New function.
5705 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
5706 argument from declaration.
5707 (_bfd_generic_reloc_link_order): Declare.
5708 (_bfd_count_link_order_relocs): Declare.
5709 * libbfd.h: Rebuilt.
5710 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
5711 call to _bfd_generic_link_add_one_symbol.
5712 (NAME(aout,final_link)): Account for link_order relocs when
5713 allocating space for relocations. Handle them after handling all
5715 (aout_link_reloc_link_order): New function.
5716 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
5717 call to _bfd_generic_link_add_one_symbol.
5718 (ecoff_bfd_final_link): Account for link_order relocs when
5719 allocating space for relocations. Handle them in link_order loop.
5720 (ecoff_link_write_external): Set the storage class of a defined
5721 linker created symbol based on the section it is in. Correct
5722 bfd_link_hash_weak case to use .sc rather than .st.
5723 (ecoff_reloc_link_order): New function.
5724 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5726 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
5728 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
5731 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5732 bfd_zmalloc. Free a pointer, not a union.
5733 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5735 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5737 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5739 * som.c (bfd_section_from_som_symbol): Only to do the value
5740 comparison for function symbols within executables.
5742 * som.c (bfd_section_from_som_symbol): Renamed from
5743 som_section_from_subspace_index. Pass in a native SOM symbol.
5744 For executables, iterate through the sections to find out
5745 which contains the symbol's address rather than using the
5746 symbol_info field. (symbol_info has a different meaning for
5747 dynamicly linked executables.)
5749 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5752 * som.c (som_begin_writing): Fix braino (one call to align
5753 space/subspace data was done unconditionally rather than
5754 just for executables.)
5756 * som.c (som_begin_writing): Align text in all executables to
5757 make HPUX kernel happy. Fixes strip/objcopy for shared
5760 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5762 * som.c (som_begin_writing): Account for alignment needs of
5763 subspaces too when writing executables. Never request a negative
5764 bss size. Fixes some problems with demand paged executables,
5765 still having problems with pure executables and shared executables.
5767 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5769 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5770 bfd_zalloc for rawptr, because later on we may call free, not
5773 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5774 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5775 * cisco-core.c: New file.
5776 * Makefile.in: Change accordingly.
5777 * configure.in: Recognize cisco_core_vec.
5778 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5779 * targets.c: Add cisco_core_vec.
5780 * bfd-in2.h: Rebuilt.
5782 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5784 * som.h (som_copyable_section_data_struct): New structure
5785 containing all the private section information which needs
5786 to be copied from input section to output section during
5788 (som_section_data_struct): Remove several fields now in
5789 som_copyable_section_data_struct. Make the space and
5790 subspace dictionaries be pointers (to save space when
5791 only reading objects).
5793 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5794 some references changed. Allocate a copyable data stucture if
5795 none exists. Store info into the copyable data structure.
5796 (bfd_som_set_subsection_attributes): Likewise.
5797 (som_is_space, som_is_subspace, som_is_container): New functions.
5798 Use these instead of directly accessing private data.
5799 (som_prep_headers): Allocate space and subspace headers here.
5800 Fill in some fields in the space/subspace headers from the
5802 (som_bfd_copy_private_section_data): Only copy the stuff
5803 that we really need to make objcopy and strip work. Allocate
5804 the copy_data structure for the output bfd before copying.
5806 * som.h (struct som_exec_data): New structure to hold exec
5807 info that must be preserved when running objcopy/strip.
5808 (struct somdata): Add new "exec_data" field and accessor
5809 macro. Add some comments on how the various fields are used.
5810 (som_section_data_struct): Make is_space and is_subspace bitfields.
5811 Delete unused subspace_index. All references now use the
5812 target_index field within the section structure itself.
5814 * som.c (make_unique_section): Delete unused declaration.
5815 (som_bfd_copy_private_bfd_data): New function.
5816 (som_object_setup): Allocate space for and save exec information
5817 that needs to be copied during objcopy/strip.
5818 (som_mkobject): Do not allocate space for a file header here.
5819 It is not used when only reading SOM objects.
5820 (som_prep_headers): Allocate space for and attach a file header
5821 to the output bfd. For executables, use the saved system_id
5822 value rather than trying to guess the right value. Do not abort
5823 wwhen setting file_hdr->entry* for executables.
5824 (som_begin_writing): For executables, set the exec_entry and
5826 (som_copy_private_backend_section_data): Always return a value.
5828 * libhppa.h (PA_PAGESIZE): Define.
5830 * som.c (SOM_ALIGN): Define.
5831 (som_begin_writing): If writing an executable, initialize all
5832 fields in the exec header to zero. Update fields in the exec
5833 header as sizes of loadable subspaces are computed. Carefully
5834 preserve alignments when building executables. Actually write the
5835 exec after all the fields are filled in.
5837 * Better long-filename handling. Reads SOM ABI compliant extended
5838 names, but doesn't quite write compliant extended names yet.
5839 * som.c (som_slurp_extended_name_table): Delete function. The
5840 generic code will handle things correctly.
5841 (som_slurp_armap): Seek to the beginning of the next member.
5842 (normalize): New function.
5843 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5844 name table into account when computing the file offsets in the
5845 SOM dictionary. Make sure to align to an even boundary.
5846 (som_write_armap): Initialize the checksum to zero.
5847 (ar_maxchars): Fix. Opps.
5849 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5851 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5852 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5854 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5856 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5857 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5858 * bfd-in2.h: Regenerated.
5860 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5861 this was also named trad_unix_bfd_copy_private_bfd_data.
5863 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5865 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5866 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5867 returns NULL, it is not an error. It's possible that some of
5868 these checks are not necessary (because the size can never be
5869 zero), but putting in the checks is the conservative thing to do
5870 in light of the fact that some of these malloc calls replaced
5871 unchecked alloca calls, in which a zero argument would work fine.
5873 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5875 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5876 duplicate definition.
5877 (osf_core_bfd_is_local_label): Define.
5879 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5880 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5881 failure indication, it merely means there are no relocs.
5883 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5884 after NAME, since SunOS /bin/cc can't handle it.
5886 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5888 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5889 From sukes@glue.umd.edu (Tasuki Hirata).
5891 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5893 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5894 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5895 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5897 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5899 * som.c (som_prep_for_fixups): Detect section symbols based
5900 on either the lack of private data or the symbol flags. Do not
5901 munge section symbol names anymore -- they no longer confuse GDB.
5902 (som_begin_writing): Leave space for an exec header if writing
5904 (som_slurp_symbol_table): Recognize both forms of section symbol
5905 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5906 section symbols to be the name of the section they represent.
5907 Debugging symbols begin with "L$0\001", not just "L$".
5909 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5911 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5913 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5914 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5915 and bfd_is_local_label.
5917 * targets.c: Add new entries to the bfd_target structure.
5919 * bfd.c (bfd_copy_private_bfd_data): New definition.
5921 * section.c (bfd_copy_private_section_data): New definition.
5923 * syms.c (bfd_is_local_label): New definition.
5925 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5927 * libbfd.c (bfd_generic_is_local_label): New function.
5929 * *-core.c: Provide default definitions for new functions in
5930 the target vector which all point to bfd_false.
5932 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5933 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5934 Default new vectors for copying private backend data to bfd_true.
5935 Default new vector for determining if a symbol is a local label
5936 to bfd_generic_is_local_label.
5938 * som.c (som_bfd_copy_private_section_data): New function.
5939 (som_bfd_is_local_label): New function.
5940 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5942 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5944 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5946 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5948 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5951 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5952 Indent some of them to GNU standards.
5954 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5955 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5956 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5957 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5958 Update copyright years.
5960 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5962 * som.c (som_prep_for_fixups): A relocation involving the section
5963 symbol for the *ABS* section is really a relocation involving
5965 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5966 undefined symbols. Correctly distinguish between debugger symbols
5967 and section symbols.
5969 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5970 for spaces and subspaces.
5972 * som.c (som_bfd_count_ar_symbols): Fix typo.
5974 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5975 HAS_RELOC based on the object's magic number.
5976 (make_unique_section): Delete function. BFD and its users are
5977 prepared to handle multiple sections with the same name.
5978 (setup_sections): Allocate space on the BFD's obstack to hold
5979 section names. Use bfd_make_setion_anyway rather than the
5980 obsolete make_unique_section.
5981 (som_prep_headers): Choose the correct SOM magic number based
5983 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5985 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5987 * elf32-ppc.c: Renamed from elf32-powerpc.c.
5988 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
5989 * Makefile.in, configure.in: Corresponding changes.
5991 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5993 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
5995 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5997 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5998 is always located at the start of the data section to allow
5999 recovery of the dynamic info from a stripped executable.
6000 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6003 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6005 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6006 cruft (like the #pragma alloca for AIX).
6007 In addition to that problem, the C alloca calls xmalloc, which
6008 means checking for being out of memory can't work right. The
6009 following changes remove all uses of alloca from BFD.
6010 * hosts/solaris2.h: Remove alloca cruft.
6011 * som.c: Replace alloca with a fixed size auto array.
6012 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
6013 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
6014 sunos.c: Replace alloca with malloc and appropriate error checking and
6016 * linker.c: Replace alloca with obstack_alloc.
6017 * libbfd.h: Rebuilt.
6019 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6021 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6024 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6026 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6027 Elf*_Off typedefs by their expansion, the typedefs have been
6028 removed from include/elf/internal.h.
6029 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6030 SHT_PROGBITS section.
6032 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6034 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6038 * configure.host: Recognize i[34]86-sequent-*.
6040 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6041 return from bfd_seek indicates an error.
6042 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6043 TRAD_CORE_STACK_OFFSET.
6044 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6045 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6047 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6049 * som.[ch]: Do not include libhppa.h in som.c, instead include
6052 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6053 include it in elf32-hppa.h.
6055 * som.c (log2): Return -1 on error rather than aborting.
6056 (setup_sections): Bubble up an error from log2.
6058 * Changes to make HP C compiler happy in both traditional
6060 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6062 (bfd_som_set_section_attributes): Use unsigned int rather than
6063 unsigned char to avoid GNU-C extensions.
6064 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6065 or failure rather than aborting on failure.
6067 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6069 (bfd_som_attach_aux_hdr): Add prototype.
6070 (hppa_som-gen_reloc_type): Likewise.
6072 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6073 (hppa_look_for_stubs_in_section): Do not return false on failure
6074 until rest of code is ready to handle it. Abort for now.
6076 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6078 * bfd-in2.h: Rebuilt.
6080 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
6082 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
6083 * Makefile.in: delete an extra blank.
6084 * configure.in : Add i396os9k_vec.
6086 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
6088 * config.bfd : Add i386-os9k.
6089 * config/i386-os9k.mt : Newly add os9k target makefile.
6091 * i386os9k.c : new file to handle os9k format bfd.
6092 * Makefile.in : Handle new file i386os9k.c
6093 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
6094 * cache.c : Initialize cache_sentinel to 0.
6096 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6098 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
6099 action in case where caller specified no argument relocation.
6100 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6101 right in the original relocation and the stub's relocation.
6103 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
6104 unused symbols argument.
6106 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
6107 than asymbol * for original target symbol. All callers changed.
6108 Set reloc->sym_ptr_ptr appropriately.
6109 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
6110 (hppa_elf_look_for_stubs_in_section): No longer need symbols
6111 argument. Use the output symbols when canonicalizing the relocs,
6112 creating them if necessary.
6114 * linker.c (_bfd_generic_link_output_symbols): Do not
6115 rebuild/clobber the output symbols if they already exist.
6117 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
6119 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
6120 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
6121 * bfd-in2.h: Rebuilt.
6123 * srec.c (hex_value): Always set to a size of 256 bytes.
6124 (srec_init): Cosmetic changes.
6126 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6128 * elf32-hppa.c: Second half of major cleanup. More comments,
6129 PARAMize and staticize rest of functions. Delete unused
6130 functions. Delete unused/unnecessary arguments to some functions.
6131 Group static vars together. Abort for bad errors until we have
6132 error code propogation working. Work on spacing and indention.
6133 Add FIXMEs for unresolved problems. Use enums rather than
6134 #defines for lots of things. Merge two functions which build
6135 linker stubs into a single function (so they can easily share a
6136 ton of common code).

6360 bother processing them.

8337 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
8340 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
8341 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
8342 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
8343 MY_bfd_seclet_link): Define.
8344 (MY_bfd_reloc_type_lookup): Rename from
8345 MY_reloc_howto_type_lookup.
8346 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
8347 (MY(vec)): Use JUMP_TABLE rather than listing functions.
8348 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
8349 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
8350 terms of MY, because that causes a recusive invocation of CAT when
8351 expanded within JUMP_TABLE, and ANSI compilers don't expand
8353 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
8354 MY_reloc_howto_type_lookup, and don't define in terms of MY.
8355 (MY_canonicalize_reloc): Don't define in terms of MY.
8356 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
8357 than listing functions.
