2570 an empty .plt section.
2571 (elf32_sparc_relocate_section): For a GOT reloc against a global
2572 symbol when no dynamic object was seen, initialize the contents of
2573 the .got section. For a GOT reloc against a local symbol, only

6112 relocs when allocating space for relocations. Set SEC_RELOC flag
6113 for any section which has relocs. Handle link_order relocs in
6114 link_order loop. Use _bfd_generic_link_add_symbols_collect for
6115 add_symbls entry point.
6117 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6118 counting relocs. Set SEC_RELOC flag for any section which has
6121 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
6123 * linker.c (_bfd_generic_link_add_symbols): Just call
6124 generic_link_add_symbols.
6125 (_bfd_generic_link_add_symbols_collect): New function, like
6126 _bfd_generic_link_add_symbols but also collect constructors and
6127 destructors by name as collect2 does.
6128 (generic_link_add_symbols): New function, like old
6129 _bfd_generic_link_add_symbols but with collect argument.
6130 (generic_link_add_object_symbols): Take collect argument.

6142 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
6143 for first character in an extended name.
6144 (_bfd_write_archive_contents): If ar_padchar == '/', then use
6145 "//" as the name of the special archive member holding the
6146 extended name table.
6148 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6150 Support for link_order types which generate relocs in order to
6151 support -Ur in the linker.
6152 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6153 from call to _bfd_generic_link_add_one_symbol.
6154 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6155 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6156 instead of bitsize to add_to_set call back.
6157 (_bfd_generic_final_link): Account for link_order relocs when
6158 allocating space for relocations. Handle them in link_order loop.
6159 (_bfd_generic_reloc_link_order): New function.
6160 (_bfd_default_link_order): If a reloc_link_order is seen here,
6162 (_bfd_count_link_order_relocs): New function.
6163 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
6164 argument from declaration.
6165 (_bfd_generic_reloc_link_order): Declare.
6166 (_bfd_count_link_order_relocs): Declare.
6167 * libbfd.h: Rebuilt.
6168 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
6169 call to _bfd_generic_link_add_one_symbol.
6170 (NAME(aout,final_link)): Account for link_order relocs when

6175 call to _bfd_generic_link_add_one_symbol.
6176 (ecoff_bfd_final_link): Account for link_order relocs when
6177 allocating space for relocations. Handle them in link_order loop.
6178 (ecoff_link_write_external): Set the storage class of a defined
6179 linker created symbol based on the section it is in. Correct
6180 bfd_link_hash_weak case to use .sc rather than .st.
6181 (ecoff_reloc_link_order): New function.
6182 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6184 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
6186 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
6189 * cisco-core.c (cisco_core_file_p): Only pass one argument to
6190 bfd_zmalloc. Free a pointer, not a union.
6191 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6193 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6195 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6197 * som.c (bfd_section_from_som_symbol): Only to do the value
6198 comparison for function symbols within executables.
6200 * som.c (bfd_section_from_som_symbol): Renamed from
6201 som_section_from_subspace_index. Pass in a native SOM symbol.
6202 For executables, iterate through the sections to find out
6203 which contains the symbol's address rather than using the
6204 symbol_info field. (symbol_info has a different meaning for
6205 dynamicly linked executables.)
6207 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6210 * som.c (som_begin_writing): Fix braino (one call to align
6211 space/subspace data was done unconditionally rather than
6212 just for executables.)
6214 * som.c (som_begin_writing): Align text in all executables to
6215 make HPUX kernel happy. Fixes strip/objcopy for shared
6218 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6220 * som.c (som_begin_writing): Account for alignment needs of
6221 subspaces too when writing executables. Never request a negative
6222 bss size. Fixes some problems with demand paged executables,
6223 still having problems with pure executables and shared executables.
6225 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6227 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6228 bfd_zalloc for rawptr, because later on we may call free, not
6231 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6232 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6233 * cisco-core.c: New file.
6234 * Makefile.in: Change accordingly.
6235 * configure.in: Recognize cisco_core_vec.
6236 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6237 * targets.c: Add cisco_core_vec.
6238 * bfd-in2.h: Rebuilt.
6240 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6242 * som.h (som_copyable_section_data_struct): New structure
6243 containing all the private section information which needs
6244 to be copied from input section to output section during
6246 (som_section_data_struct): Remove several fields now in
6247 som_copyable_section_data_struct. Make the space and
6248 subspace dictionaries be pointers (to save space when
6249 only reading objects).
6251 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6252 some references changed. Allocate a copyable data stucture if
6253 none exists. Store info into the copyable data structure.
6254 (bfd_som_set_subsection_attributes): Likewise.
6255 (som_is_space, som_is_subspace, som_is_container): New functions.
6256 Use these instead of directly accessing private data.
6257 (som_prep_headers): Allocate space and subspace headers here.
6258 Fill in some fields in the space/subspace headers from the
6260 (som_bfd_copy_private_section_data): Only copy the stuff
6261 that we really need to make objcopy and strip work. Allocate
6262 the copy_data structure for the output bfd before copying.
6264 * som.h (struct som_exec_data): New structure to hold exec
6265 info that must be preserved when running objcopy/strip.
6266 (struct somdata): Add new "exec_data" field and accessor
6267 macro. Add some comments on how the various fields are used.
6268 (som_section_data_struct): Make is_space and is_subspace bitfields.
6269 Delete unused subspace_index. All references now use the
6270 target_index field within the section structure itself.
6272 * som.c (make_unique_section): Delete unused declaration.
6273 (som_bfd_copy_private_bfd_data): New function.
6274 (som_object_setup): Allocate space for and save exec information
6275 that needs to be copied during objcopy/strip.
6276 (som_mkobject): Do not allocate space for a file header here.
6277 It is not used when only reading SOM objects.
6278 (som_prep_headers): Allocate space for and attach a file header
6279 to the output bfd. For executables, use the saved system_id
6280 value rather than trying to guess the right value. Do not abort
6281 wwhen setting file_hdr->entry* for executables.
6282 (som_begin_writing): For executables, set the exec_entry and
6284 (som_copy_private_backend_section_data): Always return a value.
6286 * libhppa.h (PA_PAGESIZE): Define.
6288 * som.c (SOM_ALIGN): Define.
6289 (som_begin_writing): If writing an executable, initialize all
6290 fields in the exec header to zero. Update fields in the exec
6291 header as sizes of loadable subspaces are computed. Carefully
6292 preserve alignments when building executables. Actually write the
6293 exec after all the fields are filled in.
6295 * Better long-filename handling. Reads SOM ABI compliant extended
6296 names, but doesn't quite write compliant extended names yet.
6297 * som.c (som_slurp_extended_name_table): Delete function. The
6298 generic code will handle things correctly.
6299 (som_slurp_armap): Seek to the beginning of the next member.
6300 (normalize): New function.
6301 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6302 name table into account when computing the file offsets in the
6303 SOM dictionary. Make sure to align to an even boundary.
6304 (som_write_armap): Initialize the checksum to zero.
6305 (ar_maxchars): Fix. Opps.
6307 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6309 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6310 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6312 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6314 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6315 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6316 * bfd-in2.h: Regenerated.
6318 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6319 this was also named trad_unix_bfd_copy_private_bfd_data.
6321 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6323 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6324 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6325 returns NULL, it is not an error. It's possible that some of
6326 these checks are not necessary (because the size can never be
6327 zero), but putting in the checks is the conservative thing to do
6328 in light of the fact that some of these malloc calls replaced
6329 unchecked alloca calls, in which a zero argument would work fine.
6331 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6333 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6334 duplicate definition.
6335 (osf_core_bfd_is_local_label): Define.
6337 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6338 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6339 failure indication, it merely means there are no relocs.
6341 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6342 after NAME, since SunOS /bin/cc can't handle it.
6344 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6346 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6347 From sukes@glue.umd.edu (Tasuki Hirata).
6349 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6351 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6352 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6353 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6355 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6357 * som.c (som_prep_for_fixups): Detect section symbols based
6358 on either the lack of private data or the symbol flags. Do not
6359 munge section symbol names anymore -- they no longer confuse GDB.
6360 (som_begin_writing): Leave space for an exec header if writing
6362 (som_slurp_symbol_table): Recognize both forms of section symbol
6363 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6364 section symbols to be the name of the section they represent.
6365 Debugging symbols begin with "L$0\001", not just "L$".
6367 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6369 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6371 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6372 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6373 and bfd_is_local_label.
6375 * targets.c: Add new entries to the bfd_target structure.
6377 * bfd.c (bfd_copy_private_bfd_data): New definition.
6379 * section.c (bfd_copy_private_section_data): New definition.
6381 * syms.c (bfd_is_local_label): New definition.
6383 * libbfd-in.h (bfd_generic_is_local_label): Declare.
6385 * libbfd.c (bfd_generic_is_local_label): New function.
6387 * *-core.c: Provide default definitions for new functions in
6388 the target vector which all point to bfd_false.
6390 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6391 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6392 Default new vectors for copying private backend data to bfd_true.
6393 Default new vector for determining if a symbol is a local label
6394 to bfd_generic_is_local_label.
6396 * som.c (som_bfd_copy_private_section_data): New function.
6397 (som_bfd_is_local_label): New function.
6398 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6400 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6402 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6404 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6406 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6409 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6410 Indent some of them to GNU standards.
6412 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6413 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6414 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6415 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6416 Update copyright years.
6418 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6420 * som.c (som_prep_for_fixups): A relocation involving the section
6421 symbol for the *ABS* section is really a relocation involving
6423 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6424 undefined symbols. Correctly distinguish between debugger symbols
6425 and section symbols.
6427 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6428 for spaces and subspaces.
6430 * som.c (som_bfd_count_ar_symbols): Fix typo.
6432 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6433 HAS_RELOC based on the object's magic number.
6434 (make_unique_section): Delete function. BFD and its users are
6435 prepared to handle multiple sections with the same name.
6436 (setup_sections): Allocate space on the BFD's obstack to hold
6437 section names. Use bfd_make_setion_anyway rather than the
6438 obsolete make_unique_section.
6439 (som_prep_headers): Choose the correct SOM magic number based
6441 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6443 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6445 * elf32-ppc.c: Renamed from elf32-powerpc.c.

6455 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6456 is always located at the start of the data section to allow
6457 recovery of the dynamic info from a stripped executable.
6458 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6461 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6463 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6464 cruft (like the #pragma alloca for AIX).
6465 In addition to that problem, the C alloca calls xmalloc, which
6466 means checking for being out of memory can't work right. The
6467 following changes remove all uses of alloca from BFD.
6468 * hosts/solaris2.h: Remove alloca cruft.
6469 * som.c: Replace alloca with a fixed size auto array.

6475 * libbfd.h: Rebuilt.
6477 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6479 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6482 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6484 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6485 Elf*_Off typedefs by their expansion, the typedefs have been
6486 removed from include/elf/internal.h.
6487 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6488 SHT_PROGBITS section.
6490 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6492 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6496 * configure.host: Recognize i[34]86-sequent-*.
6498 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6499 return from bfd_seek indicates an error.
6500 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6501 TRAD_CORE_STACK_OFFSET.
6502 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6503 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6505 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6507 * som.[ch]: Do not include libhppa.h in som.c, instead include
6510 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6511 include it in elf32-hppa.h.
6513 * som.c (log2): Return -1 on error rather than aborting.
6514 (setup_sections): Bubble up an error from log2.
6516 * Changes to make HP C compiler happy in both traditional
6518 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6520 (bfd_som_set_section_attributes): Use unsigned int rather than
6521 unsigned char to avoid GNU-C extensions.
6522 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6523 or failure rather than aborting on failure.
6525 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6527 (bfd_som_attach_aux_hdr): Add prototype.
6528 (hppa_som-gen_reloc_type): Likewise.
6530 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6531 (hppa_look_for_stubs_in_section): Do not return false on failure
6532 until rest of code is ready to handle it. Abort for now.
6534 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6536 * bfd-in2.h: Rebuilt.
6538 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

6557 action in case where caller specified no argument relocation.
6558 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
6559 right in the original relocation and the stub's relocation.

6592 #defines for lots of things. Merge two functions which build
6593 linker stubs into a single function (so they can easily share a

6642 COMPLEX relocation support (it's never used anyway).
6643 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

6818 bother processing them.
6819 (b_out_get_relocated_section_contents): Set reloc_done. Assert

8761 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
8762 in last change. Always rebuild symbol extension section the first
8763 time though if output sections exist (fixes ld -r problems).
8765 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)
8767 * Makefile.in: Add .PHONY for check and installcheck rules.
8769 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
8771 * libbfd-in.h (artdata): Use long, not time_t for portability, at
8772 least to HPUX. File below is a derived file.

8776 * libbfd.h (artdata): Use long, not time_t for portability, at
8779 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
8781 * config.bfd: Use bigmips for mips*-*-bsd*.
8783 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
8785 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
8786 Handle symbol number of zero.
8788 * reloc.c (enum bfd_reloc_code_real): Added
8789 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
8790 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
8791 * bfd-in2.h: Rebuilt.
8792 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
8793 BFD_RELOC_MIPS_LITERAL.
8794 * elf32-mips.c (mips_reloc_map): Handle new relocs.
8795 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
8798 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
8799 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
8800 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
8801 MY_bfd_seclet_link): Define.
8802 (MY_bfd_reloc_type_lookup): Rename from
8803 MY_reloc_howto_type_lookup.
8804 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
8805 (MY(vec)): Use JUMP_TABLE rather than listing functions.
8806 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
8807 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
8808 terms of MY, because that causes a recusive invocation of CAT when
8809 expanded within JUMP_TABLE, and ANSI compilers don't expand
8811 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
8812 MY_reloc_howto_type_lookup, and don't define in terms of MY.
8813 (MY_canonicalize_reloc): Don't define in terms of MY.
8814 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
8815 than listing functions.
8817 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
8819 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
