2575 an empty .plt section.
2576 (elf32_sparc_relocate_section): For a GOT reloc against a global
2577 symbol when no dynamic object was seen, initialize the contents of

6119 link_order loop. Use _bfd_generic_link_add_symbols_collect for
6120 add_symbls entry point.
6122 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6123 counting relocs. Set SEC_RELOC flag for any section which has

6128 * linker.c (_bfd_generic_link_add_symbols): Just call
6129 generic_link_add_symbols.
6130 (_bfd_generic_link_add_symbols_collect): New function, like
6131 _bfd_generic_link_add_symbols but also collect constructors and
6132 destructors by name as collect2 does.
6133 (generic_link_add_symbols): New function, like old
6134 _bfd_generic_link_add_symbols but with collect argument.
6135 (generic_link_add_object_symbols): Take collect argument.

6147 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
6148 for first character in an extended name.
6149 (_bfd_write_archive_contents): If ar_padchar == '/', then use
6150 "//" as the name of the special archive member holding the
6151 extended name table.
6153 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6155 Support for link_order types which generate relocs in order to
6156 support -Ur in the linker.
6157 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6158 from call to _bfd_generic_link_add_one_symbol.
6159 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6160 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6161 instead of bitsize to add_to_set call back.
6162 (_bfd_generic_final_link): Account for link_order relocs when
6163 allocating space for relocations. Handle them in link_order loop.
6164 (_bfd_generic_reloc_link_order): New function.
6165 (_bfd_default_link_order): If a reloc_link_order is seen here,
6167 (_bfd_count_link_order_relocs): New function.
6168 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
6169 argument from declaration.
6170 (_bfd_generic_reloc_link_order): Declare.
6171 (_bfd_count_link_order_relocs): Declare.
6172 * libbfd.h: Rebuilt.
6173 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
6174 call to _bfd_generic_link_add_one_symbol.
6175 (NAME(aout,final_link)): Account for link_order relocs when

6180 call to _bfd_generic_link_add_one_symbol.
6181 (ecoff_bfd_final_link): Account for link_order relocs when
6182 allocating space for relocations. Handle them in link_order loop.
6183 (ecoff_link_write_external): Set the storage class of a defined
6184 linker created symbol based on the section it is in. Correct
6185 bfd_link_hash_weak case to use .sc rather than .st.
6186 (ecoff_reloc_link_order): New function.
6187 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6189 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
6191 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
6194 * cisco-core.c (cisco_core_file_p): Only pass one argument to
6195 bfd_zmalloc. Free a pointer, not a union.
6196 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6198 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6200 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6202 * som.c (bfd_section_from_som_symbol): Only to do the value
6203 comparison for function symbols within executables.
6205 * som.c (bfd_section_from_som_symbol): Renamed from
6206 som_section_from_subspace_index. Pass in a native SOM symbol.
6207 For executables, iterate through the sections to find out
6208 which contains the symbol's address rather than using the
6209 symbol_info field. (symbol_info has a different meaning for
6210 dynamicly linked executables.)
6212 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6215 * som.c (som_begin_writing): Fix braino (one call to align
6216 space/subspace data was done unconditionally rather than
6217 just for executables.)
6219 * som.c (som_begin_writing): Align text in all executables to
6220 make HPUX kernel happy. Fixes strip/objcopy for shared
6223 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6225 * som.c (som_begin_writing): Account for alignment needs of
6226 subspaces too when writing executables. Never request a negative
6227 bss size. Fixes some problems with demand paged executables,
6228 still having problems with pure executables and shared executables.
6230 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6232 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6233 bfd_zalloc for rawptr, because later on we may call free, not
6236 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6237 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6238 * cisco-core.c: New file.
6239 * Makefile.in: Change accordingly.
6240 * configure.in: Recognize cisco_core_vec.
6241 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6242 * targets.c: Add cisco_core_vec.
6243 * bfd-in2.h: Rebuilt.
6245 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6247 * som.h (som_copyable_section_data_struct): New structure
6248 containing all the private section information which needs
6249 to be copied from input section to output section during
6251 (som_section_data_struct): Remove several fields now in
6252 som_copyable_section_data_struct. Make the space and
6253 subspace dictionaries be pointers (to save space when
6254 only reading objects).
6256 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6257 some references changed. Allocate a copyable data stucture if
6258 none exists. Store info into the copyable data structure.
6259 (bfd_som_set_subsection_attributes): Likewise.
6260 (som_is_space, som_is_subspace, som_is_container): New functions.
6261 Use these instead of directly accessing private data.
6262 (som_prep_headers): Allocate space and subspace headers here.
6263 Fill in some fields in the space/subspace headers from the
6265 (som_bfd_copy_private_section_data): Only copy the stuff
6266 that we really need to make objcopy and strip work. Allocate
6267 the copy_data structure for the output bfd before copying.
6269 * som.h (struct som_exec_data): New structure to hold exec
6270 info that must be preserved when running objcopy/strip.
6271 (struct somdata): Add new "exec_data" field and accessor
6272 macro. Add some comments on how the various fields are used.
6273 (som_section_data_struct): Make is_space and is_subspace bitfields.
6274 Delete unused subspace_index. All references now use the
6275 target_index field within the section structure itself.
6277 * som.c (make_unique_section): Delete unused declaration.
6278 (som_bfd_copy_private_bfd_data): New function.
6279 (som_object_setup): Allocate space for and save exec information
6280 that needs to be copied during objcopy/strip.
6281 (som_mkobject): Do not allocate space for a file header here.
6282 It is not used when only reading SOM objects.
6283 (som_prep_headers): Allocate space for and attach a file header
6284 to the output bfd. For executables, use the saved system_id
6285 value rather than trying to guess the right value. Do not abort
6286 wwhen setting file_hdr->entry* for executables.
6287 (som_begin_writing): For executables, set the exec_entry and
6289 (som_copy_private_backend_section_data): Always return a value.
6291 * libhppa.h (PA_PAGESIZE): Define.
6293 * som.c (SOM_ALIGN): Define.
6294 (som_begin_writing): If writing an executable, initialize all
6295 fields in the exec header to zero. Update fields in the exec
6296 header as sizes of loadable subspaces are computed. Carefully
6297 preserve alignments when building executables. Actually write the
6298 exec after all the fields are filled in.
6300 * Better long-filename handling. Reads SOM ABI compliant extended
6301 names, but doesn't quite write compliant extended names yet.
6302 * som.c (som_slurp_extended_name_table): Delete function. The
6303 generic code will handle things correctly.
6304 (som_slurp_armap): Seek to the beginning of the next member.
6305 (normalize): New function.
6306 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6307 name table into account when computing the file offsets in the
6308 SOM dictionary. Make sure to align to an even boundary.
6309 (som_write_armap): Initialize the checksum to zero.
6310 (ar_maxchars): Fix. Opps.
6312 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6314 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6315 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6317 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6319 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6320 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6321 * bfd-in2.h: Regenerated.
6323 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6324 this was also named trad_unix_bfd_copy_private_bfd_data.
6326 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6328 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6329 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6330 returns NULL, it is not an error. It's possible that some of
6331 these checks are not necessary (because the size can never be
6332 zero), but putting in the checks is the conservative thing to do
6333 in light of the fact that some of these malloc calls replaced
6334 unchecked alloca calls, in which a zero argument would work fine.
6336 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6338 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6339 duplicate definition.
6340 (osf_core_bfd_is_local_label): Define.
6342 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6343 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6344 failure indication, it merely means there are no relocs.
6346 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6347 after NAME, since SunOS /bin/cc can't handle it.
6349 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6351 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6352 From sukes@glue.umd.edu (Tasuki Hirata).
6354 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6356 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6357 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6358 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6360 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6362 * som.c (som_prep_for_fixups): Detect section symbols based
6363 on either the lack of private data or the symbol flags. Do not
6364 munge section symbol names anymore -- they no longer confuse GDB.
6365 (som_begin_writing): Leave space for an exec header if writing
6367 (som_slurp_symbol_table): Recognize both forms of section symbol
6368 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6369 section symbols to be the name of the section they represent.
6370 Debugging symbols begin with "L$0\001", not just "L$".
6372 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6374 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6376 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6377 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6378 and bfd_is_local_label.
6380 * targets.c: Add new entries to the bfd_target structure.
6382 * bfd.c (bfd_copy_private_bfd_data): New definition.
6384 * section.c (bfd_copy_private_section_data): New definition.
6386 * syms.c (bfd_is_local_label): New definition.
6388 * libbfd-in.h (bfd_generic_is_local_label): Declare.
6390 * libbfd.c (bfd_generic_is_local_label): New function.
6392 * *-core.c: Provide default definitions for new functions in
6393 the target vector which all point to bfd_false.
6395 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6396 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6397 Default new vectors for copying private backend data to bfd_true.
6398 Default new vector for determining if a symbol is a local label
6399 to bfd_generic_is_local_label.
6401 * som.c (som_bfd_copy_private_section_data): New function.
6402 (som_bfd_is_local_label): New function.
6403 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6405 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6407 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6409 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6411 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6414 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6415 Indent some of them to GNU standards.
6417 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6418 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6419 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6420 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6421 Update copyright years.
6423 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6425 * som.c (som_prep_for_fixups): A relocation involving the section
6426 symbol for the *ABS* section is really a relocation involving
6428 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6429 undefined symbols. Correctly distinguish between debugger symbols
6430 and section symbols.
6432 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6433 for spaces and subspaces.
6435 * som.c (som_bfd_count_ar_symbols): Fix typo.
6437 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6438 HAS_RELOC based on the object's magic number.
6439 (make_unique_section): Delete function. BFD and its users are
6440 prepared to handle multiple sections with the same name.
6441 (setup_sections): Allocate space on the BFD's obstack to hold
6442 section names. Use bfd_make_setion_anyway rather than the
6443 obsolete make_unique_section.
6444 (som_prep_headers): Choose the correct SOM magic number based
6446 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

6460 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6461 is always located at the start of the data section to allow
6462 recovery of the dynamic info from a stripped executable.
6463 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6466 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6468 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6469 cruft (like the #pragma alloca for AIX).
6470 In addition to that problem, the C alloca calls xmalloc, which
6471 means checking for being out of memory can't work right. The
6472 following changes remove all uses of alloca from BFD.
6473 * hosts/solaris2.h: Remove alloca cruft.
6474 * som.c: Replace alloca with a fixed size auto array.

6480 * libbfd.h: Rebuilt.
6482 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6484 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6487 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6489 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6490 Elf*_Off typedefs by their expansion, the typedefs have been
6491 removed from include/elf/internal.h.
6492 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6493 SHT_PROGBITS section.
6495 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6497 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

6501 * configure.host: Recognize i[34]86-sequent-*.
6503 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6504 return from bfd_seek indicates an error.
6505 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6506 TRAD_CORE_STACK_OFFSET.
6507 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6508 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6510 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6512 * som.[ch]: Do not include libhppa.h in som.c, instead include
6515 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
6516 include it in elf32-hppa.h.
6518 * som.c (log2): Return -1 on error rather than aborting.
6519 (setup_sections): Bubble up an error from log2.
6521 * Changes to make HP C compiler happy in both traditional
6523 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
6525 (bfd_som_set_section_attributes): Use unsigned int rather than
6526 unsigned char to avoid GNU-C extensions.
6527 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
6528 or failure rather than aborting on failure.
6530 * som.h (bfd_som_set_section_attributes): Fix prototype to match
6532 (bfd_som_attach_aux_hdr): Add prototype.
6533 (hppa_som-gen_reloc_type): Likewise.
6535 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
6536 (hppa_look_for_stubs_in_section): Do not return false on failure
6537 until rest of code is ready to handle it. Abort for now.
6539 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6541 * bfd-in2.h: Rebuilt.
6543 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

6823 bother processing them.
6824 (b_out_get_relocated_section_contents): Set reloc_done. Assert

7527 The sparc (and possibly other?) NLM format requires a different
7528 way to write exports, so add a write_export field to the backend
7529 data (and set it to NULL for everything but the sparc).

8765 * From Pete Hoogenboom (hoogen@cs.utah.edu)
8766 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
8767 in last change. Always rebuild symbol extension section the first
8768 time though if output sections exist (fixes ld -r problems).
8770 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)

8781 * libbfd.h (artdata): Use long, not time_t for portability, at
8784 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
8786 * config.bfd: Use bigmips for mips*-*-bsd*.
8788 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
8790 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
8791 Handle symbol number of zero.
8793 * reloc.c (enum bfd_reloc_code_real): Added
8794 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
8795 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
8796 * bfd-in2.h: Rebuilt.
8797 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
8798 BFD_RELOC_MIPS_LITERAL.
8799 * elf32-mips.c (mips_reloc_map): Handle new relocs.
8800 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
8803 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
8804 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
8805 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
8806 MY_bfd_seclet_link): Define.
8807 (MY_bfd_reloc_type_lookup): Rename from
8808 MY_reloc_howto_type_lookup.
8809 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
8810 (MY(vec)): Use JUMP_TABLE rather than listing functions.
8811 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
8812 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
8813 terms of MY, because that causes a recusive invocation of CAT when
8814 expanded within JUMP_TABLE, and ANSI compilers don't expand
8816 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
8817 MY_reloc_howto_type_lookup, and don't define in terms of MY.
8818 (MY_canonicalize_reloc): Don't define in terms of MY.
8819 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
8820 than listing functions.
