2335 (_bfd_construct_extended_name_table): Check the name of an archive
2336 entry which is not being extended, and correct it if it is wrong.

2600 of the .plt section.
2601 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
2602 seen, skip most of this function, and force the size of the
2603 .rela.got section to zero. Strip empty reloc sections, and strip
2604 an empty .plt section.
2605 (elf32_sparc_relocate_section): For a GOT reloc against a global
2606 symbol when no dynamic object was seen, initialize the contents of
2607 the .got section. For a GOT reloc against a local symbol, only
2608 create a R_SPARC_RELATIVE reloc when generating a shared object.
2609 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
2610 create a PLT entry as a R_SPARC_WDISP30 reloc.
2611 (elf32_sparc_finish_dynamic_sections): Only fiddle with the

6135 in asymbol udata field.
6137 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6139 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
6140 reloc, used in embedded PIC code.
6141 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
6142 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

6148 link_order loop. Use _bfd_generic_link_add_symbols_collect for
6149 add_symbls entry point.
6151 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6152 counting relocs. Set SEC_RELOC flag for any section which has

6158 generic_link_add_symbols.
6159 (_bfd_generic_link_add_symbols_collect): New function, like
6160 _bfd_generic_link_add_symbols but also collect constructors and
6161 destructors by name as collect2 does.
6162 (generic_link_add_symbols): New function, like old
6163 _bfd_generic_link_add_symbols but with collect argument.
6164 (generic_link_add_object_symbols): Take collect argument.

6176 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
6177 for first character in an extended name.
6178 (_bfd_write_archive_contents): If ar_padchar == '/', then use
6179 "//" as the name of the special archive member holding the
6180 extended name table.
6182 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6184 Support for link_order types which generate relocs in order to
6185 support -Ur in the linker.
6186 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6187 from call to _bfd_generic_link_add_one_symbol.
6188 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6189 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6190 instead of bitsize to add_to_set call back.
6191 (_bfd_generic_final_link): Account for link_order relocs when
6192 allocating space for relocations. Handle them in link_order loop.
6193 (_bfd_generic_reloc_link_order): New function.
6194 (_bfd_default_link_order): If a reloc_link_order is seen here,
6196 (_bfd_count_link_order_relocs): New function.
6197 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
6198 argument from declaration.
6199 (_bfd_generic_reloc_link_order): Declare.
6200 (_bfd_count_link_order_relocs): Declare.

6202 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
6203 call to _bfd_generic_link_add_one_symbol.

6210 (ecoff_bfd_final_link): Account for link_order relocs when
6211 allocating space for relocations. Handle them in link_order loop.
6212 (ecoff_link_write_external): Set the storage class of a defined
6213 linker created symbol based on the section it is in. Correct
6214 bfd_link_hash_weak case to use .sc rather than .st.
6215 (ecoff_reloc_link_order): New function.
6216 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6218 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

6223 * cisco-core.c (cisco_core_file_p): Only pass one argument to
6224 bfd_zmalloc. Free a pointer, not a union.
6225 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6227 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6229 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6231 * som.c (bfd_section_from_som_symbol): Only to do the value
6232 comparison for function symbols within executables.
6234 * som.c (bfd_section_from_som_symbol): Renamed from
6235 som_section_from_subspace_index. Pass in a native SOM symbol.
6236 For executables, iterate through the sections to find out
6237 which contains the symbol's address rather than using the
6238 symbol_info field. (symbol_info has a different meaning for
6239 dynamicly linked executables.)
6241 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6244 * som.c (som_begin_writing): Fix braino (one call to align
6245 space/subspace data was done unconditionally rather than
6246 just for executables.)
6248 * som.c (som_begin_writing): Align text in all executables to
6249 make HPUX kernel happy. Fixes strip/objcopy for shared
6252 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6254 * som.c (som_begin_writing): Account for alignment needs of
6255 subspaces too when writing executables. Never request a negative
6256 bss size. Fixes some problems with demand paged executables,
6257 still having problems with pure executables and shared executables.
6259 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6261 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6262 bfd_zalloc for rawptr, because later on we may call free, not
6265 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6266 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6267 * cisco-core.c: New file.
6268 * Makefile.in: Change accordingly.
6269 * configure.in: Recognize cisco_core_vec.
6270 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6271 * targets.c: Add cisco_core_vec.
6272 * bfd-in2.h: Rebuilt.
6274 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6276 * som.h (som_copyable_section_data_struct): New structure
6277 containing all the private section information which needs
6278 to be copied from input section to output section during
6280 (som_section_data_struct): Remove several fields now in
6281 som_copyable_section_data_struct. Make the space and
6282 subspace dictionaries be pointers (to save space when
6283 only reading objects).
6285 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6286 some references changed. Allocate a copyable data stucture if
6287 none exists. Store info into the copyable data structure.
6288 (bfd_som_set_subsection_attributes): Likewise.
6289 (som_is_space, som_is_subspace, som_is_container): New functions.
6290 Use these instead of directly accessing private data.
6291 (som_prep_headers): Allocate space and subspace headers here.
6292 Fill in some fields in the space/subspace headers from the
6294 (som_bfd_copy_private_section_data): Only copy the stuff
6295 that we really need to make objcopy and strip work. Allocate
6296 the copy_data structure for the output bfd before copying.
6298 * som.h (struct som_exec_data): New structure to hold exec
6299 info that must be preserved when running objcopy/strip.
6300 (struct somdata): Add new "exec_data" field and accessor
6301 macro. Add some comments on how the various fields are used.
6302 (som_section_data_struct): Make is_space and is_subspace bitfields.
6303 Delete unused subspace_index. All references now use the
6304 target_index field within the section structure itself.
6306 * som.c (make_unique_section): Delete unused declaration.
6307 (som_bfd_copy_private_bfd_data): New function.
6308 (som_object_setup): Allocate space for and save exec information
6309 that needs to be copied during objcopy/strip.
6310 (som_mkobject): Do not allocate space for a file header here.
6311 It is not used when only reading SOM objects.
6312 (som_prep_headers): Allocate space for and attach a file header
6313 to the output bfd. For executables, use the saved system_id
6314 value rather than trying to guess the right value. Do not abort
6315 wwhen setting file_hdr->entry* for executables.
6316 (som_begin_writing): For executables, set the exec_entry and
6318 (som_copy_private_backend_section_data): Always return a value.
6320 * libhppa.h (PA_PAGESIZE): Define.
6322 * som.c (SOM_ALIGN): Define.
6323 (som_begin_writing): If writing an executable, initialize all
6324 fields in the exec header to zero. Update fields in the exec
6325 header as sizes of loadable subspaces are computed. Carefully
6326 preserve alignments when building executables. Actually write the
6327 exec after all the fields are filled in.
6329 * Better long-filename handling. Reads SOM ABI compliant extended
6330 names, but doesn't quite write compliant extended names yet.
6331 * som.c (som_slurp_extended_name_table): Delete function. The
6332 generic code will handle things correctly.
6333 (som_slurp_armap): Seek to the beginning of the next member.
6334 (normalize): New function.
6335 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6336 name table into account when computing the file offsets in the
6337 SOM dictionary. Make sure to align to an even boundary.
6338 (som_write_armap): Initialize the checksum to zero.
6339 (ar_maxchars): Fix. Opps.
6341 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6343 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6344 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6346 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6348 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6349 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6350 * bfd-in2.h: Regenerated.
6352 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6353 this was also named trad_unix_bfd_copy_private_bfd_data.
6355 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6357 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6358 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6359 returns NULL, it is not an error. It's possible that some of
6360 these checks are not necessary (because the size can never be
6361 zero), but putting in the checks is the conservative thing to do
6362 in light of the fact that some of these malloc calls replaced
6363 unchecked alloca calls, in which a zero argument would work fine.
6365 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6367 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6368 duplicate definition.
6369 (osf_core_bfd_is_local_label): Define.
6371 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6372 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6373 failure indication, it merely means there are no relocs.
6375 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6376 after NAME, since SunOS /bin/cc can't handle it.
6378 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6380 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6381 From sukes@glue.umd.edu (Tasuki Hirata).
6383 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6385 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6386 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6387 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6389 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6391 * som.c (som_prep_for_fixups): Detect section symbols based
6392 on either the lack of private data or the symbol flags. Do not
6393 munge section symbol names anymore -- they no longer confuse GDB.
6394 (som_begin_writing): Leave space for an exec header if writing
6396 (som_slurp_symbol_table): Recognize both forms of section symbol
6397 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6398 section symbols to be the name of the section they represent.
6399 Debugging symbols begin with "L$0\001", not just "L$".
6401 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6403 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6405 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6406 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6407 and bfd_is_local_label.
6409 * targets.c: Add new entries to the bfd_target structure.
6411 * bfd.c (bfd_copy_private_bfd_data): New definition.
6413 * section.c (bfd_copy_private_section_data): New definition.

6419 * libbfd.c (bfd_generic_is_local_label): New function.
6421 * *-core.c: Provide default definitions for new functions in
6422 the target vector which all point to bfd_false.
6424 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6425 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6426 Default new vectors for copying private backend data to bfd_true.
6427 Default new vector for determining if a symbol is a local label
6428 to bfd_generic_is_local_label.
6430 * som.c (som_bfd_copy_private_section_data): New function.
6431 (som_bfd_is_local_label): New function.
6432 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6434 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6436 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6438 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6440 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6443 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6444 Indent some of them to GNU standards.
6446 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6447 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6448 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6449 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6450 Update copyright years.
6452 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6454 * som.c (som_prep_for_fixups): A relocation involving the section
6455 symbol for the *ABS* section is really a relocation involving
6457 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6458 undefined symbols. Correctly distinguish between debugger symbols
6459 and section symbols.
6461 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6462 for spaces and subspaces.
6464 * som.c (som_bfd_count_ar_symbols): Fix typo.
6466 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6467 HAS_RELOC based on the object's magic number.
6468 (make_unique_section): Delete function. BFD and its users are
6469 prepared to handle multiple sections with the same name.
6470 (setup_sections): Allocate space on the BFD's obstack to hold
6471 section names. Use bfd_make_setion_anyway rather than the
6472 obsolete make_unique_section.
6473 (som_prep_headers): Choose the correct SOM magic number based
6475 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
6477 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
6479 * elf32-ppc.c: Renamed from elf32-powerpc.c.

6489 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6490 is always located at the start of the data section to allow
6491 recovery of the dynamic info from a stripped executable.
6492 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
6495 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6497 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
6498 cruft (like the #pragma alloca for AIX).
6499 In addition to that problem, the C alloca calls xmalloc, which
6500 means checking for being out of memory can't work right. The
6501 following changes remove all uses of alloca from BFD.
6502 * hosts/solaris2.h: Remove alloca cruft.
6503 * som.c: Replace alloca with a fixed size auto array.
6504 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

6508 * linker.c: Replace alloca with obstack_alloc.
6509 * libbfd.h: Rebuilt.
6511 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
6513 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
6516 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
6518 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
6519 Elf*_Off typedefs by their expansion, the typedefs have been
6520 removed from include/elf/internal.h.
6521 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
6522 SHT_PROGBITS section.
6524 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6526 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
6528 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
6530 * configure.host: Recognize i[34]86-sequent-*.
6532 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
6533 return from bfd_seek indicates an error.
6534 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
6535 TRAD_CORE_STACK_OFFSET.
6536 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
6537 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
6539 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6541 * som.[ch]: Do not include libhppa.h in som.c, instead include

6852 bother processing them.
6853 (b_out_get_relocated_section_contents): Set reloc_done. Assert

7556 The sparc (and possibly other?) NLM format requires a different
7557 way to write exports, so add a write_export field to the backend
7558 data (and set it to NULL for everything but the sparc).
