6113 * som.c (som_begin_writing): New approach at dealing with holes
6114 in executables left by the HP linker. Does not rely on subspace
6115 alignments as subspaces are *NOT* guaranteed to be properly
6116 aligned in an executable (can you believe that!).
6118 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6120 * som.c (som_get_section_contents): New function. Do not try

6128 failing bfd_read, bfd_write, or bfd_seek. In a few places
6129 (like som_object_p) override the error status set by bfd_read.

6166 required by expansions. Set s and unset h when converting a reloc
6167 from undefined to section. Change handling of PC relative relocs:
6168 if against a section, they are correct in the object file, if
6169 against an external symbol they are pcrel_offset.
6170 (mips_relax_section): New function.
6171 (mips_relax_pcrel16): New function.

6256 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
6257 reloc, used in embedded PIC code.
6258 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
6259 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

6265 link_order loop. Use _bfd_generic_link_add_symbols_collect for
6266 add_symbls entry point.
6268 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
6269 counting relocs. Set SEC_RELOC flag for any section which has

6297 extended name table.
6299 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6301 Support for link_order types which generate relocs in order to
6302 support -Ur in the linker.
6303 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
6304 from call to _bfd_generic_link_add_one_symbol.
6305 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
6306 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
6307 instead of bitsize to add_to_set call back.
6308 (_bfd_generic_final_link): Account for link_order relocs when
6309 allocating space for relocations. Handle them in link_order loop.
6310 (_bfd_generic_reloc_link_order): New function.

6327 (ecoff_bfd_final_link): Account for link_order relocs when
6328 allocating space for relocations. Handle them in link_order loop.
6329 (ecoff_link_write_external): Set the storage class of a defined
6330 linker created symbol based on the section it is in. Correct
6331 bfd_link_hash_weak case to use .sc rather than .st.
6332 (ecoff_reloc_link_order): New function.
6333 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
6335 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

6341 bfd_zmalloc. Free a pointer, not a union.
6342 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
6344 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6346 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
6348 * som.c (bfd_section_from_som_symbol): Only to do the value
6349 comparison for function symbols within executables.
6351 * som.c (bfd_section_from_som_symbol): Renamed from
6352 som_section_from_subspace_index. Pass in a native SOM symbol.
6353 For executables, iterate through the sections to find out
6354 which contains the symbol's address rather than using the
6355 symbol_info field. (symbol_info has a different meaning for
6356 dynamicly linked executables.)
6358 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
6361 * som.c (som_begin_writing): Fix braino (one call to align
6362 space/subspace data was done unconditionally rather than
6363 just for executables.)
6365 * som.c (som_begin_writing): Align text in all executables to
6366 make HPUX kernel happy. Fixes strip/objcopy for shared
6369 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6371 * som.c (som_begin_writing): Account for alignment needs of
6372 subspaces too when writing executables. Never request a negative
6373 bss size. Fixes some problems with demand paged executables,
6374 still having problems with pure executables and shared executables.
6376 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6378 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
6379 bfd_zalloc for rawptr, because later on we may call free, not
6382 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
6383 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
6384 * cisco-core.c: New file.
6385 * Makefile.in: Change accordingly.
6386 * configure.in: Recognize cisco_core_vec.
6387 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
6388 * targets.c: Add cisco_core_vec.
6389 * bfd-in2.h: Rebuilt.
6391 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6393 * som.h (som_copyable_section_data_struct): New structure
6394 containing all the private section information which needs
6395 to be copied from input section to output section during
6397 (som_section_data_struct): Remove several fields now in
6398 som_copyable_section_data_struct. Make the space and
6399 subspace dictionaries be pointers (to save space when
6400 only reading objects).
6402 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
6403 some references changed. Allocate a copyable data stucture if
6404 none exists. Store info into the copyable data structure.
6405 (bfd_som_set_subsection_attributes): Likewise.
6406 (som_is_space, som_is_subspace, som_is_container): New functions.
6407 Use these instead of directly accessing private data.
6408 (som_prep_headers): Allocate space and subspace headers here.
6409 Fill in some fields in the space/subspace headers from the
6411 (som_bfd_copy_private_section_data): Only copy the stuff
6412 that we really need to make objcopy and strip work. Allocate
6413 the copy_data structure for the output bfd before copying.
6415 * som.h (struct som_exec_data): New structure to hold exec
6416 info that must be preserved when running objcopy/strip.
6417 (struct somdata): Add new "exec_data" field and accessor
6418 macro. Add some comments on how the various fields are used.
6419 (som_section_data_struct): Make is_space and is_subspace bitfields.
6420 Delete unused subspace_index. All references now use the
6421 target_index field within the section structure itself.
6423 * som.c (make_unique_section): Delete unused declaration.
6424 (som_bfd_copy_private_bfd_data): New function.
6425 (som_object_setup): Allocate space for and save exec information
6426 that needs to be copied during objcopy/strip.
6427 (som_mkobject): Do not allocate space for a file header here.
6428 It is not used when only reading SOM objects.
6429 (som_prep_headers): Allocate space for and attach a file header
6430 to the output bfd. For executables, use the saved system_id
6431 value rather than trying to guess the right value. Do not abort
6432 wwhen setting file_hdr->entry* for executables.
6433 (som_begin_writing): For executables, set the exec_entry and
6435 (som_copy_private_backend_section_data): Always return a value.
6437 * libhppa.h (PA_PAGESIZE): Define.
6439 * som.c (SOM_ALIGN): Define.
6440 (som_begin_writing): If writing an executable, initialize all
6441 fields in the exec header to zero. Update fields in the exec
6442 header as sizes of loadable subspaces are computed. Carefully
6443 preserve alignments when building executables. Actually write the
6444 exec after all the fields are filled in.
6446 * Better long-filename handling. Reads SOM ABI compliant extended
6447 names, but doesn't quite write compliant extended names yet.
6448 * som.c (som_slurp_extended_name_table): Delete function. The
6449 generic code will handle things correctly.
6450 (som_slurp_armap): Seek to the beginning of the next member.
6451 (normalize): New function.
6452 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
6453 name table into account when computing the file offsets in the
6454 SOM dictionary. Make sure to align to an even boundary.
6455 (som_write_armap): Initialize the checksum to zero.
6456 (ar_maxchars): Fix. Opps.
6458 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6460 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
6461 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
6463 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
6465 * bfd-in.h (BFD_VERSION): Use @VERSION@.
6466 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
6467 * bfd-in2.h: Regenerated.
6469 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
6470 this was also named trad_unix_bfd_copy_private_bfd_data.
6472 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6474 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
6475 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
6476 returns NULL, it is not an error. It's possible that some of
6477 these checks are not necessary (because the size can never be
6478 zero), but putting in the checks is the conservative thing to do
6479 in light of the fact that some of these malloc calls replaced
6480 unchecked alloca calls, in which a zero argument would work fine.
6482 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6484 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
6485 duplicate definition.
6486 (osf_core_bfd_is_local_label): Define.
6488 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
6489 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
6490 failure indication, it merely means there are no relocs.
6492 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
6493 after NAME, since SunOS /bin/cc can't handle it.
6495 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
6497 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
6498 From sukes@glue.umd.edu (Tasuki Hirata).
6500 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
6502 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
6503 all that convoluted stuff with NAME, CAT3, etc. The convoluted
6504 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
6506 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6508 * som.c (som_prep_for_fixups): Detect section symbols based
6509 on either the lack of private data or the symbol flags. Do not
6510 munge section symbol names anymore -- they no longer confuse GDB.
6511 (som_begin_writing): Leave space for an exec header if writing
6513 (som_slurp_symbol_table): Recognize both forms of section symbol
6514 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
6515 section symbols to be the name of the section they represent.
6516 Debugging symbols begin with "L$0\001", not just "L$".
6518 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
6520 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
6522 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
6523 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
6524 and bfd_is_local_label.
6526 * targets.c: Add new entries to the bfd_target structure.

6539 the target vector which all point to bfd_false.
6541 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
6542 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
6543 Default new vectors for copying private backend data to bfd_true.
6544 Default new vector for determining if a symbol is a local label
6545 to bfd_generic_is_local_label.

6615 cruft (like the #pragma alloca for AIX).
6616 In addition to that problem, the C alloca calls xmalloc, which

7646 undefined, look it up in the linker hash table.
7648 * aoutx.h (translate_symbol_table): The string index 0 has a

7673 The sparc (and possibly other?) NLM format requires a different
7674 way to write exports, so add a write_export field to the backend
7675 data (and set it to NULL for everything but the sparc).
