6128 required by expansions. Set s and unset h when converting a reloc
6129 from undefined to section. Change handling of PC relative relocs:
6130 if against a section, they are correct in the object file, if
6131 against an external symbol they are pcrel_offset.
6132 (mips_relax_section): New function.
6133 (mips_relax_pcrel16): New function.

6218 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
6219 reloc, used in embedded PIC code.
6220 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

6228 add_symbls entry point.
6230 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6231 counting relocs. Set SEC_RELOC flag for any section which has

6259 extended name table.
6261 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6263 Support for link_order types which generate relocs in order to
6264 support -Ur in the linker.
6265 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6266 from call to _bfd_generic_link_add_one_symbol.
6267 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6268 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6269 instead of bitsize to add_to_set call back.
6270 (_bfd_generic_final_link): Account for link_order relocs when
6271 allocating space for relocations. Handle them in link_order loop.
6272 (_bfd_generic_reloc_link_order): New function.

6289 (ecoff_bfd_final_link): Account for link_order relocs when
6290 allocating space for relocations. Handle them in link_order loop.
6291 (ecoff_link_write_external): Set the storage class of a defined
6292 linker created symbol based on the section it is in. Correct
6293 bfd_link_hash_weak case to use .sc rather than .st.
6294 (ecoff_reloc_link_order): New function.
6295 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6297 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

6302 * cisco-core.c (cisco_core_file_p): Only pass one argument to
6303 bfd_zmalloc. Free a pointer, not a union.
6304 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6306 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6308 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6310 * som.c (bfd_section_from_som_symbol): Only to do the value
6311 comparison for function symbols within executables.
6313 * som.c (bfd_section_from_som_symbol): Renamed from
6314 som_section_from_subspace_index. Pass in a native SOM symbol.
6315 For executables, iterate through the sections to find out
6316 which contains the symbol's address rather than using the
6317 symbol_info field. (symbol_info has a different meaning for
6318 dynamicly linked executables.)
6320 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6323 * som.c (som_begin_writing): Fix braino (one call to align
6324 space/subspace data was done unconditionally rather than
6325 just for executables.)
6327 * som.c (som_begin_writing): Align text in all executables to
6328 make HPUX kernel happy. Fixes strip/objcopy for shared
6331 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6333 * som.c (som_begin_writing): Account for alignment needs of
6334 subspaces too when writing executables. Never request a negative
6335 bss size. Fixes some problems with demand paged executables,
6336 still having problems with pure executables and shared executables.
6338 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6340 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6341 bfd_zalloc for rawptr, because later on we may call free, not
6344 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6345 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6346 * cisco-core.c: New file.
6347 * Makefile.in: Change accordingly.
6348 * configure.in: Recognize cisco_core_vec.
6349 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6350 * targets.c: Add cisco_core_vec.
6351 * bfd-in2.h: Rebuilt.
6353 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6355 * som.h (som_copyable_section_data_struct): New structure
6356 containing all the private section information which needs
6357 to be copied from input section to output section during
6359 (som_section_data_struct): Remove several fields now in
6360 som_copyable_section_data_struct. Make the space and
6361 subspace dictionaries be pointers (to save space when
6362 only reading objects).
6364 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6365 some references changed. Allocate a copyable data stucture if
6366 none exists. Store info into the copyable data structure.
6367 (bfd_som_set_subsection_attributes): Likewise.
6368 (som_is_space, som_is_subspace, som_is_container): New functions.
6369 Use these instead of directly accessing private data.
6370 (som_prep_headers): Allocate space and subspace headers here.
6371 Fill in some fields in the space/subspace headers from the
6373 (som_bfd_copy_private_section_data): Only copy the stuff
6374 that we really need to make objcopy and strip work. Allocate
6375 the copy_data structure for the output bfd before copying.
6377 * som.h (struct som_exec_data): New structure to hold exec
6378 info that must be preserved when running objcopy/strip.
6379 (struct somdata): Add new "exec_data" field and accessor
6380 macro. Add some comments on how the various fields are used.
6381 (som_section_data_struct): Make is_space and is_subspace bitfields.
6382 Delete unused subspace_index. All references now use the
6383 target_index field within the section structure itself.
6385 * som.c (make_unique_section): Delete unused declaration.
6386 (som_bfd_copy_private_bfd_data): New function.
6387 (som_object_setup): Allocate space for and save exec information
6388 that needs to be copied during objcopy/strip.
6389 (som_mkobject): Do not allocate space for a file header here.
6390 It is not used when only reading SOM objects.
6391 (som_prep_headers): Allocate space for and attach a file header
6392 to the output bfd. For executables, use the saved system_id
6393 value rather than trying to guess the right value. Do not abort
6394 wwhen setting file_hdr->entry* for executables.
6395 (som_begin_writing): For executables, set the exec_entry and
6397 (som_copy_private_backend_section_data): Always return a value.
6399 * libhppa.h (PA_PAGESIZE): Define.
6401 * som.c (SOM_ALIGN): Define.
6402 (som_begin_writing): If writing an executable, initialize all
6403 fields in the exec header to zero. Update fields in the exec
6404 header as sizes of loadable subspaces are computed. Carefully
6405 preserve alignments when building executables. Actually write the
6406 exec after all the fields are filled in.
6408 * Better long-filename handling. Reads SOM ABI compliant extended
6409 names, but doesn't quite write compliant extended names yet.
6410 * som.c (som_slurp_extended_name_table): Delete function. The
6411 generic code will handle things correctly.
6412 (som_slurp_armap): Seek to the beginning of the next member.
6413 (normalize): New function.
6414 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6415 name table into account when computing the file offsets in the
6416 SOM dictionary. Make sure to align to an even boundary.
6417 (som_write_armap): Initialize the checksum to zero.
6418 (ar_maxchars): Fix. Opps.
6420 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6422 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6423 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6425 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6427 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6428 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6429 * bfd-in2.h: Regenerated.
6431 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6432 this was also named trad_unix_bfd_copy_private_bfd_data.
6434 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6436 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6437 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6438 returns NULL, it is not an error. It's possible that some of
6439 these checks are not necessary (because the size can never be
6440 zero), but putting in the checks is the conservative thing to do
6441 in light of the fact that some of these malloc calls replaced
6442 unchecked alloca calls, in which a zero argument would work fine.
6444 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6446 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6447 duplicate definition.
6448 (osf_core_bfd_is_local_label): Define.
6450 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6451 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6452 failure indication, it merely means there are no relocs.
6454 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6455 after NAME, since SunOS /bin/cc can't handle it.
6457 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6459 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6460 From sukes@glue.umd.edu (Tasuki Hirata).
6462 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6464 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6465 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6466 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6468 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6470 * som.c (som_prep_for_fixups): Detect section symbols based
6471 on either the lack of private data or the symbol flags. Do not
6472 munge section symbol names anymore -- they no longer confuse GDB.
6473 (som_begin_writing): Leave space for an exec header if writing
6475 (som_slurp_symbol_table): Recognize both forms of section symbol
6476 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6477 section symbols to be the name of the section they represent.
6478 Debugging symbols begin with "L$0\001", not just "L$".
6480 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6482 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6484 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6485 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6486 and bfd_is_local_label.
6488 * targets.c: Add new entries to the bfd_target structure.

6501 the target vector which all point to bfd_false.
6503 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6504 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6505 Default new vectors for copying private backend data to bfd_true.
6506 Default new vector for determining if a symbol is a local label
6507 to bfd_generic_is_local_label.
6509 * som.c (som_bfd_copy_private_section_data): New function.
6510 (som_bfd_is_local_label): New function.
6511 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
6513 * elf32-hppa.c (hppa_elf_is_local_label): New function.
6515 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6517 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
6519 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
6522 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
6523 Indent some of them to GNU standards.
6525 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
6526 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
6527 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
6528 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
6529 Update copyright years.
6531 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6533 * som.c (som_prep_for_fixups): A relocation involving the section
6534 symbol for the *ABS* section is really a relocation involving

6577 cruft (like the #pragma alloca for AIX).
6578 In addition to that problem, the C alloca calls xmalloc, which

7635 The sparc (and possibly other?) NLM format requires a different
7636 way to write exports, so add a write_export field to the backend
7637 data (and set it to NULL for everything but the sparc).

8773 * elfcode.h (elf_object_p): Rather than looking through an array
8774 of architectures, get the ELF EM_xxx code from the backend
