2655 an empty .plt section.
2656 (elf32_sparc_relocate_section): For a GOT reloc against a global
2657 symbol when no dynamic object was seen, initialize the contents of
2658 the .got section. For a GOT reloc against a local symbol, only

6100 required by expansions. Set s and unset h when converting a reloc
6101 from undefined to section. Change handling of PC relative relocs:
6102 if against a section, they are correct in the object file, if
6103 against an external symbol they are pcrel_offset.

6233 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6235 Support for link_order types which generate relocs in order to
6236 support -Ur in the linker.
6237 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6238 from call to _bfd_generic_link_add_one_symbol.
6239 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6240 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6241 instead of bitsize to add_to_set call back.
6242 (_bfd_generic_final_link): Account for link_order relocs when
6243 allocating space for relocations. Handle them in link_order loop.
6244 (_bfd_generic_reloc_link_order): New function.

6262 allocating space for relocations. Handle them in link_order loop.
6263 (ecoff_link_write_external): Set the storage class of a defined
6264 linker created symbol based on the section it is in. Correct
6265 bfd_link_hash_weak case to use .sc rather than .st.

6283 comparison for function symbols within executables.
6285 * som.c (bfd_section_from_som_symbol): Renamed from
6286 som_section_from_subspace_index. Pass in a native SOM symbol.
6287 For executables, iterate through the sections to find out
6288 which contains the symbol's address rather than using the
6289 symbol_info field. (symbol_info has a different meaning for
6290 dynamicly linked executables.)
6292 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6295 * som.c (som_begin_writing): Fix braino (one call to align
6296 space/subspace data was done unconditionally rather than
6297 just for executables.)
6299 * som.c (som_begin_writing): Align text in all executables to
6300 make HPUX kernel happy. Fixes strip/objcopy for shared
6303 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6305 * som.c (som_begin_writing): Account for alignment needs of
6306 subspaces too when writing executables. Never request a negative
6307 bss size. Fixes some problems with demand paged executables,
6308 still having problems with pure executables and shared executables.
6310 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6312 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6313 bfd_zalloc for rawptr, because later on we may call free, not
6316 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6317 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6318 * cisco-core.c: New file.

6325 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6327 * som.h (som_copyable_section_data_struct): New structure
6328 containing all the private section information which needs
6329 to be copied from input section to output section during
6331 (som_section_data_struct): Remove several fields now in
6332 som_copyable_section_data_struct. Make the space and
6333 subspace dictionaries be pointers (to save space when
6334 only reading objects).
6336 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6337 some references changed. Allocate a copyable data stucture if
6338 none exists. Store info into the copyable data structure.
6339 (bfd_som_set_subsection_attributes): Likewise.
6340 (som_is_space, som_is_subspace, som_is_container): New functions.
6341 Use these instead of directly accessing private data.
6342 (som_prep_headers): Allocate space and subspace headers here.
6343 Fill in some fields in the space/subspace headers from the
6345 (som_bfd_copy_private_section_data): Only copy the stuff
6346 that we really need to make objcopy and strip work. Allocate
6347 the copy_data structure for the output bfd before copying.
6349 * som.h (struct som_exec_data): New structure to hold exec
6350 info that must be preserved when running objcopy/strip.
6351 (struct somdata): Add new "exec_data" field and accessor
6352 macro. Add some comments on how the various fields are used.
6353 (som_section_data_struct): Make is_space and is_subspace bitfields.
6354 Delete unused subspace_index. All references now use the
6355 target_index field within the section structure itself.
6357 * som.c (make_unique_section): Delete unused declaration.
6358 (som_bfd_copy_private_bfd_data): New function.
6359 (som_object_setup): Allocate space for and save exec information
6360 that needs to be copied during objcopy/strip.
6361 (som_mkobject): Do not allocate space for a file header here.
6362 It is not used when only reading SOM objects.
6363 (som_prep_headers): Allocate space for and attach a file header
6364 to the output bfd. For executables, use the saved system_id
6365 value rather than trying to guess the right value. Do not abort
6366 wwhen setting file_hdr->entry* for executables.
6367 (som_begin_writing): For executables, set the exec_entry and
6369 (som_copy_private_backend_section_data): Always return a value.
6371 * libhppa.h (PA_PAGESIZE): Define.
6373 * som.c (SOM_ALIGN): Define.
6374 (som_begin_writing): If writing an executable, initialize all
6375 fields in the exec header to zero. Update fields in the exec
6376 header as sizes of loadable subspaces are computed. Carefully
6377 preserve alignments when building executables. Actually write the
6378 exec after all the fields are filled in.
6380 * Better long-filename handling. Reads SOM ABI compliant extended
6381 names, but doesn't quite write compliant extended names yet.
6382 * som.c (som_slurp_extended_name_table): Delete function. The
6383 generic code will handle things correctly.
6384 (som_slurp_armap): Seek to the beginning of the next member.
6385 (normalize): New function.
6386 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6387 name table into account when computing the file offsets in the
6388 SOM dictionary. Make sure to align to an even boundary.
6389 (som_write_armap): Initialize the checksum to zero.
6390 (ar_maxchars): Fix. Opps.

6394 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6395 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

6399 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6400 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6401 * bfd-in2.h: Regenerated.
6403 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6404 this was also named trad_unix_bfd_copy_private_bfd_data.
6406 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6408 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6409 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6410 returns NULL, it is not an error. It's possible that some of
6411 these checks are not necessary (because the size can never be
6412 zero), but putting in the checks is the conservative thing to do
6413 in light of the fact that some of these malloc calls replaced
6414 unchecked alloca calls, in which a zero argument would work fine.
6416 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6418 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6419 duplicate definition.
6420 (osf_core_bfd_is_local_label): Define.
6422 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6423 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6424 failure indication, it merely means there are no relocs.
6426 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6427 after NAME, since SunOS /bin/cc can't handle it.
6429 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6431 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6432 From sukes@glue.umd.edu (Tasuki Hirata).
6434 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6436 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6437 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6438 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6440 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6442 * som.c (som_prep_for_fixups): Detect section symbols based
6443 on either the lack of private data or the symbol flags. Do not
6444 munge section symbol names anymore -- they no longer confuse GDB.
6445 (som_begin_writing): Leave space for an exec header if writing
6447 (som_slurp_symbol_table): Recognize both forms of section symbol
6448 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6449 section symbols to be the name of the section they represent.
6450 Debugging symbols begin with "L$0\001", not just "L$".
6452 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6454 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.

6457 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6458 and bfd_is_local_label.

6476 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6477 Default new vectors for copying private backend data to bfd_true.
6478 Default new vector for determining if a symbol is a local label
6479 to bfd_generic_is_local_label.
6481 * som.c (som_bfd_copy_private_section_data): New function.
6482 (som_bfd_is_local_label): New function.
6483 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6485 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6487 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6489 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6491 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6494 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6495 Indent some of them to GNU standards.
6497 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6498 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

6500 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6501 Update copyright years.
6503 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6505 * som.c (som_prep_for_fixups): A relocation involving the section
6506 symbol for the *ABS* section is really a relocation involving
6508 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
6509 undefined symbols. Correctly distinguish between debugger symbols
6510 and section symbols.
6512 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
6513 for spaces and subspaces.
6515 * som.c (som_bfd_count_ar_symbols): Fix typo.
6517 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
6518 HAS_RELOC based on the object's magic number.
6519 (make_unique_section): Delete function. BFD and its users are
6520 prepared to handle multiple sections with the same name.
6521 (setup_sections): Allocate space on the BFD's obstack to hold
6522 section names. Use bfd_make_setion_anyway rather than the
6523 obsolete make_unique_section.
6524 (som_prep_headers): Choose the correct SOM magic number based
6526 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

6540 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
6541 is always located at the start of the data section to allow

6549 cruft (like the #pragma alloca for AIX).
6550 In addition to that problem, the C alloca calls xmalloc, which
6551 means checking for being out of memory can't work right. The
6552 following changes remove all uses of alloca from BFD.

6903 bother processing them.
6904 (b_out_get_relocated_section_contents): Set reloc_done. Assert
6905 that bfd_get_section_contents returns true. Check that relocs are

6988 Make all callers of malloc or realloc (including via obstacks)
6989 check the result for NULL. Most set bfd_error to no_memory and
6990 return in that case; a few are harder to fix, and are marked

6994 hppa_elf_build_long_branch_stub): Check bfd_make_empty_symbol return.

7607 The sparc (and possibly other?) NLM format requires a different
7608 way to write exports, so add a write_export field to the backend
7609 data (and set it to NULL for everything but the sparc).

7775 sym_filepos as well.
7776 (ecoff_get_extr): Use ifdmap instead of ifdbase.

7848 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

7851 * configure.in (nlm32_alpha_vec): Set target64 to true.
7853 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
7854 different, so there is no point to providing a generic one.
7855 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
7856 in the backend accessor macros; that should no longer be possible.
7857 * targets.c (target_vector): Removed nlm32_big_generic_vec,
