2204 from undefined to section. Change handling of PC relative relocs:
2205 if against a section, they are correct in the object file, if
2206 against an external symbol they are pcrel_offset.
2207 (mips_relax_section): New function.
2208 (mips_relax_pcrel16): New function.

2334 extended name table.
2336 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2338 Support for link_order types which generate relocs in order to
2339 support -Ur in the linker.
2340 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2341 from call to _bfd_generic_link_add_one_symbol.
2342 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2343 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2344 instead of bitsize to add_to_set call back.
2345 (_bfd_generic_final_link): Account for link_order relocs when
2346 allocating space for relocations. Handle them in link_order loop.
2347 (_bfd_generic_reloc_link_order): New function.

2365 allocating space for relocations. Handle them in link_order loop.
2366 (ecoff_link_write_external): Set the storage class of a defined
2367 linker created symbol based on the section it is in. Correct
2368 bfd_link_hash_weak case to use .sc rather than .st.
2369 (ecoff_reloc_link_order): New function.
2370 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2372 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2378 bfd_zmalloc. Free a pointer, not a union.
2379 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2381 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2383 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2385 * som.c (bfd_section_from_som_symbol): Only to do the value
2386 comparison for function symbols within executables.
2388 * som.c (bfd_section_from_som_symbol): Renamed from
2389 som_section_from_subspace_index. Pass in a native SOM symbol.
2390 For executables, iterate through the sections to find out
2391 which contains the symbol's address rather than using the
2392 symbol_info field. (symbol_info has a different meaning for
2393 dynamicly linked executables.)
2395 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2398 * som.c (som_begin_writing): Fix braino (one call to align
2399 space/subspace data was done unconditionally rather than
2400 just for executables.)
2402 * som.c (som_begin_writing): Align text in all executables to
2403 make HPUX kernel happy. Fixes strip/objcopy for shared
2406 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2408 * som.c (som_begin_writing): Account for alignment needs of
2409 subspaces too when writing executables. Never request a negative
2410 bss size. Fixes some problems with demand paged executables,
2411 still having problems with pure executables and shared executables.
2413 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2415 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2416 bfd_zalloc for rawptr, because later on we may call free, not
2419 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2420 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2421 * cisco-core.c: New file.
2422 * Makefile.in: Change accordingly.
2423 * configure.in: Recognize cisco_core_vec.
2424 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2425 * targets.c: Add cisco_core_vec.
2426 * bfd-in2.h: Rebuilt.
2428 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2430 * som.h (som_copyable_section_data_struct): New structure
2431 containing all the private section information which needs
2432 to be copied from input section to output section during
2434 (som_section_data_struct): Remove several fields now in
2435 som_copyable_section_data_struct. Make the space and
2436 subspace dictionaries be pointers (to save space when
2437 only reading objects).
2439 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2440 some references changed. Allocate a copyable data stucture if
2441 none exists. Store info into the copyable data structure.
2442 (bfd_som_set_subsection_attributes): Likewise.
2443 (som_is_space, som_is_subspace, som_is_container): New functions.
2444 Use these instead of directly accessing private data.
2445 (som_prep_headers): Allocate space and subspace headers here.
2446 Fill in some fields in the space/subspace headers from the
2448 (som_bfd_copy_private_section_data): Only copy the stuff
2449 that we really need to make objcopy and strip work. Allocate
2450 the copy_data structure for the output bfd before copying.
2452 * som.h (struct som_exec_data): New structure to hold exec
2453 info that must be preserved when running objcopy/strip.
2454 (struct somdata): Add new "exec_data" field and accessor
2455 macro. Add some comments on how the various fields are used.
2456 (som_section_data_struct): Make is_space and is_subspace bitfields.
2457 Delete unused subspace_index. All references now use the
2458 target_index field within the section structure itself.
2460 * som.c (make_unique_section): Delete unused declaration.
2461 (som_bfd_copy_private_bfd_data): New function.
2462 (som_object_setup): Allocate space for and save exec information
2463 that needs to be copied during objcopy/strip.
2464 (som_mkobject): Do not allocate space for a file header here.
2465 It is not used when only reading SOM objects.
2466 (som_prep_headers): Allocate space for and attach a file header
2467 to the output bfd. For executables, use the saved system_id
2468 value rather than trying to guess the right value. Do not abort
2469 wwhen setting file_hdr->entry* for executables.
2470 (som_begin_writing): For executables, set the exec_entry and
2472 (som_copy_private_backend_section_data): Always return a value.
2474 * libhppa.h (PA_PAGESIZE): Define.
2476 * som.c (SOM_ALIGN): Define.
2477 (som_begin_writing): If writing an executable, initialize all
2478 fields in the exec header to zero. Update fields in the exec
2479 header as sizes of loadable subspaces are computed. Carefully
2480 preserve alignments when building executables. Actually write the
2481 exec after all the fields are filled in.
2483 * Better long-filename handling. Reads SOM ABI compliant extended
2484 names, but doesn't quite write compliant extended names yet.
2485 * som.c (som_slurp_extended_name_table): Delete function. The
2486 generic code will handle things correctly.
2487 (som_slurp_armap): Seek to the beginning of the next member.
2488 (normalize): New function.
2489 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2490 name table into account when computing the file offsets in the
2491 SOM dictionary. Make sure to align to an even boundary.
2492 (som_write_armap): Initialize the checksum to zero.
2493 (ar_maxchars): Fix. Opps.
2495 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2497 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2498 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2500 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2502 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2503 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2504 * bfd-in2.h: Regenerated.
2506 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2507 this was also named trad_unix_bfd_copy_private_bfd_data.
2509 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2511 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2512 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2513 returns NULL, it is not an error. It's possible that some of
2514 these checks are not necessary (because the size can never be
2515 zero), but putting in the checks is the conservative thing to do
2516 in light of the fact that some of these malloc calls replaced
2517 unchecked alloca calls, in which a zero argument would work fine.
2519 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2521 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2522 duplicate definition.
2523 (osf_core_bfd_is_local_label): Define.
2525 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2526 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2527 failure indication, it merely means there are no relocs.
2529 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2530 after NAME, since SunOS /bin/cc can't handle it.
2532 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2534 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2535 From sukes@glue.umd.edu (Tasuki Hirata).
2537 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2539 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2540 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2541 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2543 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2545 * som.c (som_prep_for_fixups): Detect section symbols based
2546 on either the lack of private data or the symbol flags. Do not
2547 munge section symbol names anymore -- they no longer confuse GDB.
2548 (som_begin_writing): Leave space for an exec header if writing
2550 (som_slurp_symbol_table): Recognize both forms of section symbol
2551 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2552 section symbols to be the name of the section they represent.
2553 Debugging symbols begin with "L$0\001", not just "L$".
2555 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2557 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2559 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2560 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2561 and bfd_is_local_label.
2563 * targets.c: Add new entries to the bfd_target structure.

2576 the target vector which all point to bfd_false.
2578 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2579 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2580 Default new vectors for copying private backend data to bfd_true.
2581 Default new vector for determining if a symbol is a local label
2582 to bfd_generic_is_local_label.
2584 * som.c (som_bfd_copy_private_section_data): New function.
2585 (som_bfd_is_local_label): New function.
2586 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2588 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2590 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2592 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2594 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2597 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2598 Indent some of them to GNU standards.
2600 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2601 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2603 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2604 Update copyright years.

2612 undefined symbols. Correctly distinguish between debugger symbols
2613 and section symbols.

2616 for spaces and subspaces.
2618 * som.c (som_bfd_count_ar_symbols): Fix typo.

2652 cruft (like the #pragma alloca for AIX).
2653 In addition to that problem, the C alloca calls xmalloc, which
