2179 required by expansions. Set s and unset h when converting a reloc
2180 from undefined to section. Change handling of PC relative relocs:
2181 if against a section, they are correct in the object file, if
2182 against an external symbol they are pcrel_offset.

2312 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2314 Support for link_order types which generate relocs in order to
2315 support -Ur in the linker.
2316 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2317 from call to _bfd_generic_link_add_one_symbol.
2318 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2319 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR

2321 (_bfd_generic_final_link): Account for link_order relocs when
2322 allocating space for relocations. Handle them in link_order loop.

2341 allocating space for relocations. Handle them in link_order loop.
2342 (ecoff_link_write_external): Set the storage class of a defined
2343 linker created symbol based on the section it is in. Correct
2344 bfd_link_hash_weak case to use .sc rather than .st.

2362 comparison for function symbols within executables.
2364 * som.c (bfd_section_from_som_symbol): Renamed from
2365 som_section_from_subspace_index. Pass in a native SOM symbol.
2366 For executables, iterate through the sections to find out
2367 which contains the symbol's address rather than using the
2368 symbol_info field. (symbol_info has a different meaning for
2369 dynamicly linked executables.)
2371 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2374 * som.c (som_begin_writing): Fix braino (one call to align
2375 space/subspace data was done unconditionally rather than
2376 just for executables.)
2378 * som.c (som_begin_writing): Align text in all executables to
2379 make HPUX kernel happy. Fixes strip/objcopy for shared
2382 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2384 * som.c (som_begin_writing): Account for alignment needs of
2385 subspaces too when writing executables. Never request a negative
2386 bss size. Fixes some problems with demand paged executables,
2387 still having problems with pure executables and shared executables.
2389 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2391 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2392 bfd_zalloc for rawptr, because later on we may call free, not
2395 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2396 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2397 * cisco-core.c: New file.

2406 * som.h (som_copyable_section_data_struct): New structure
2407 containing all the private section information which needs
2408 to be copied from input section to output section during
2410 (som_section_data_struct): Remove several fields now in
2411 som_copyable_section_data_struct. Make the space and
2412 subspace dictionaries be pointers (to save space when
2413 only reading objects).
2415 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2416 some references changed. Allocate a copyable data stucture if
2417 none exists. Store info into the copyable data structure.
2418 (bfd_som_set_subsection_attributes): Likewise.
2419 (som_is_space, som_is_subspace, som_is_container): New functions.
2420 Use these instead of directly accessing private data.
2421 (som_prep_headers): Allocate space and subspace headers here.
2422 Fill in some fields in the space/subspace headers from the
2424 (som_bfd_copy_private_section_data): Only copy the stuff
2425 that we really need to make objcopy and strip work. Allocate
2426 the copy_data structure for the output bfd before copying.
2428 * som.h (struct som_exec_data): New structure to hold exec
2429 info that must be preserved when running objcopy/strip.
2430 (struct somdata): Add new "exec_data" field and accessor
2431 macro. Add some comments on how the various fields are used.
2432 (som_section_data_struct): Make is_space and is_subspace bitfields.
2433 Delete unused subspace_index. All references now use the
2434 target_index field within the section structure itself.
2436 * som.c (make_unique_section): Delete unused declaration.
2437 (som_bfd_copy_private_bfd_data): New function.
2438 (som_object_setup): Allocate space for and save exec information
2439 that needs to be copied during objcopy/strip.
2440 (som_mkobject): Do not allocate space for a file header here.
2441 It is not used when only reading SOM objects.
2442 (som_prep_headers): Allocate space for and attach a file header
2443 to the output bfd. For executables, use the saved system_id
2444 value rather than trying to guess the right value. Do not abort
2445 wwhen setting file_hdr->entry* for executables.
2446 (som_begin_writing): For executables, set the exec_entry and
2448 (som_copy_private_backend_section_data): Always return a value.
2450 * libhppa.h (PA_PAGESIZE): Define.
2452 * som.c (SOM_ALIGN): Define.
2453 (som_begin_writing): If writing an executable, initialize all
2454 fields in the exec header to zero. Update fields in the exec
2455 header as sizes of loadable subspaces are computed. Carefully
2456 preserve alignments when building executables. Actually write the
2457 exec after all the fields are filled in.
2459 * Better long-filename handling. Reads SOM ABI compliant extended
2460 names, but doesn't quite write compliant extended names yet.
2461 * som.c (som_slurp_extended_name_table): Delete function. The
2462 generic code will handle things correctly.
2463 (som_slurp_armap): Seek to the beginning of the next member.
2464 (normalize): New function.
2465 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2466 name table into account when computing the file offsets in the
2467 SOM dictionary. Make sure to align to an even boundary.
2468 (som_write_armap): Initialize the checksum to zero.
2469 (ar_maxchars): Fix. Opps.

2478 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2479 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2480 * bfd-in2.h: Regenerated.
2482 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2483 this was also named trad_unix_bfd_copy_private_bfd_data.
2485 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2487 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2488 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2489 returns NULL, it is not an error. It's possible that some of
2490 these checks are not necessary (because the size can never be
2491 zero), but putting in the checks is the conservative thing to do
2492 in light of the fact that some of these malloc calls replaced
2493 unchecked alloca calls, in which a zero argument would work fine.
2495 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2497 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2498 duplicate definition.
2499 (osf_core_bfd_is_local_label): Define.
2501 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2502 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2503 failure indication, it merely means there are no relocs.
2505 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2506 after NAME, since SunOS /bin/cc can't handle it.
2508 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2510 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2511 From sukes@glue.umd.edu (Tasuki Hirata).
2513 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2515 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2516 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2517 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2519 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2521 * som.c (som_prep_for_fixups): Detect section symbols based
2522 on either the lack of private data or the symbol flags. Do not
2523 munge section symbol names anymore -- they no longer confuse GDB.
2524 (som_begin_writing): Leave space for an exec header if writing
2526 (som_slurp_symbol_table): Recognize both forms of section symbol
2527 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2528 section symbols to be the name of the section they represent.
2529 Debugging symbols begin with "L$0\001", not just "L$".
2531 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2533 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2535 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2536 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2537 and bfd_is_local_label.

2555 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2556 Default new vectors for copying private backend data to bfd_true.
2557 Default new vector for determining if a symbol is a local label
2558 to bfd_generic_is_local_label.
2560 * som.c (som_bfd_copy_private_section_data): New function.
2561 (som_bfd_is_local_label): New function.
2562 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2564 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2566 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2568 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2570 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2573 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2574 Indent some of them to GNU standards.
2576 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2577 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2579 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2580 Update copyright years.
2582 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2584 * som.c (som_prep_for_fixups): A relocation involving the section
2585 symbol for the *ABS* section is really a relocation involving
2587 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2588 undefined symbols. Correctly distinguish between debugger symbols
2589 and section symbols.
2591 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2592 for spaces and subspaces.
2594 * som.c (som_bfd_count_ar_symbols): Fix typo.
2596 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2597 HAS_RELOC based on the object's magic number.
2598 (make_unique_section): Delete function. BFD and its users are
2599 prepared to handle multiple sections with the same name.
2600 (setup_sections): Allocate space on the BFD's obstack to hold
2601 section names. Use bfd_make_setion_anyway rather than the
2602 obsolete make_unique_section.
2603 (som_prep_headers): Choose the correct SOM magic number based
2605 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

2628 cruft (like the #pragma alloca for AIX).
2629 In addition to that problem, the C alloca calls xmalloc, which

3516 (only testing for m68k and vax at the moment); do verify that the
3517 preprocessor didn't trash the arch name inside the string version.

3519 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
3521 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

3659 undefined, look it up in the linker hash table.
3661 * aoutx.h (translate_symbol_table): The string index 0 has a

3686 The sparc (and possibly other?) NLM format requires a different
3687 way to write exports, so add a write_export field to the backend
3688 data (and set it to NULL for everything but the sparc).

3854 sym_filepos as well.
3855 (ecoff_get_extr): Use ifdmap instead of ifdbase.

3925 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
3927 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

3930 * configure.in (nlm32_alpha_vec): Set target64 to true.
3932 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
3933 different, so there is no point to providing a generic one.
3934 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
3935 in the backend accessor macros; that should no longer be possible.
3936 * targets.c (target_vector): Removed nlm32_big_generic_vec,
3937 nlm64_big_generic_vec, nlm64_little_generic_vec.

4824 * elfcode.h (elf_object_p): Rather than looking through an array
4825 of architectures, get the ELF EM_xxx code from the backend
4826 information. Let the generic ELF target match any EM_xxx code not
