2208 from undefined to section. Change handling of PC relative relocs:
2209 if against a section, they are correct in the object file, if
2210 against an external symbol they are pcrel_offset.
2211 (mips_relax_section): New function.
2212 (mips_relax_pcrel16): New function.

2338 extended name table.
2340 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2342 Support for link_order types which generate relocs in order to
2343 support -Ur in the linker.
2344 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2345 from call to _bfd_generic_link_add_one_symbol.
2346 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2347 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2348 instead of bitsize to add_to_set call back.
2349 (_bfd_generic_final_link): Account for link_order relocs when
2350 allocating space for relocations. Handle them in link_order loop.
2351 (_bfd_generic_reloc_link_order): New function.

2369 allocating space for relocations. Handle them in link_order loop.
2370 (ecoff_link_write_external): Set the storage class of a defined
2371 linker created symbol based on the section it is in. Correct
2372 bfd_link_hash_weak case to use .sc rather than .st.
2373 (ecoff_reloc_link_order): New function.
2374 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2376 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2382 bfd_zmalloc. Free a pointer, not a union.
2383 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2385 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2387 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2389 * som.c (bfd_section_from_som_symbol): Only to do the value
2390 comparison for function symbols within executables.
2392 * som.c (bfd_section_from_som_symbol): Renamed from
2393 som_section_from_subspace_index. Pass in a native SOM symbol.
2394 For executables, iterate through the sections to find out
2395 which contains the symbol's address rather than using the
2396 symbol_info field. (symbol_info has a different meaning for
2397 dynamicly linked executables.)
2399 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2402 * som.c (som_begin_writing): Fix braino (one call to align
2403 space/subspace data was done unconditionally rather than
2404 just for executables.)
2406 * som.c (som_begin_writing): Align text in all executables to
2407 make HPUX kernel happy. Fixes strip/objcopy for shared
2410 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2412 * som.c (som_begin_writing): Account for alignment needs of
2413 subspaces too when writing executables. Never request a negative
2414 bss size. Fixes some problems with demand paged executables,
2415 still having problems with pure executables and shared executables.
2417 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2419 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2420 bfd_zalloc for rawptr, because later on we may call free, not
2423 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2424 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2425 * cisco-core.c: New file.
2426 * Makefile.in: Change accordingly.
2427 * configure.in: Recognize cisco_core_vec.
2428 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

2432 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2434 * som.h (som_copyable_section_data_struct): New structure
2435 containing all the private section information which needs
2436 to be copied from input section to output section during
2438 (som_section_data_struct): Remove several fields now in
2439 som_copyable_section_data_struct. Make the space and
2440 subspace dictionaries be pointers (to save space when
2441 only reading objects).
2443 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2444 some references changed. Allocate a copyable data stucture if
2445 none exists. Store info into the copyable data structure.
2446 (bfd_som_set_subsection_attributes): Likewise.
2447 (som_is_space, som_is_subspace, som_is_container): New functions.
2448 Use these instead of directly accessing private data.
2449 (som_prep_headers): Allocate space and subspace headers here.
2450 Fill in some fields in the space/subspace headers from the
2452 (som_bfd_copy_private_section_data): Only copy the stuff
2453 that we really need to make objcopy and strip work. Allocate
2454 the copy_data structure for the output bfd before copying.
2456 * som.h (struct som_exec_data): New structure to hold exec
2457 info that must be preserved when running objcopy/strip.
2458 (struct somdata): Add new "exec_data" field and accessor
2459 macro. Add some comments on how the various fields are used.
2460 (som_section_data_struct): Make is_space and is_subspace bitfields.
2461 Delete unused subspace_index. All references now use the
2462 target_index field within the section structure itself.
2464 * som.c (make_unique_section): Delete unused declaration.
2465 (som_bfd_copy_private_bfd_data): New function.
2466 (som_object_setup): Allocate space for and save exec information
2467 that needs to be copied during objcopy/strip.
2468 (som_mkobject): Do not allocate space for a file header here.
2469 It is not used when only reading SOM objects.
2470 (som_prep_headers): Allocate space for and attach a file header
2471 to the output bfd. For executables, use the saved system_id
2472 value rather than trying to guess the right value. Do not abort
2473 wwhen setting file_hdr->entry* for executables.
2474 (som_begin_writing): For executables, set the exec_entry and
2476 (som_copy_private_backend_section_data): Always return a value.
2478 * libhppa.h (PA_PAGESIZE): Define.
2480 * som.c (SOM_ALIGN): Define.
2481 (som_begin_writing): If writing an executable, initialize all
2482 fields in the exec header to zero. Update fields in the exec
2483 header as sizes of loadable subspaces are computed. Carefully
2484 preserve alignments when building executables. Actually write the
2485 exec after all the fields are filled in.
2487 * Better long-filename handling. Reads SOM ABI compliant extended
2488 names, but doesn't quite write compliant extended names yet.
2489 * som.c (som_slurp_extended_name_table): Delete function. The
2490 generic code will handle things correctly.
2491 (som_slurp_armap): Seek to the beginning of the next member.
2492 (normalize): New function.
2493 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2494 name table into account when computing the file offsets in the
2495 SOM dictionary. Make sure to align to an even boundary.
2496 (som_write_armap): Initialize the checksum to zero.
2497 (ar_maxchars): Fix. Opps.
2499 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2501 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2502 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2504 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2506 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2507 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2508 * bfd-in2.h: Regenerated.
2510 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2511 this was also named trad_unix_bfd_copy_private_bfd_data.
2513 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2515 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2516 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2517 returns NULL, it is not an error. It's possible that some of
2518 these checks are not necessary (because the size can never be
2519 zero), but putting in the checks is the conservative thing to do
2520 in light of the fact that some of these malloc calls replaced
2521 unchecked alloca calls, in which a zero argument would work fine.
2523 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2525 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2526 duplicate definition.
2527 (osf_core_bfd_is_local_label): Define.
2529 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2530 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2531 failure indication, it merely means there are no relocs.
2533 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2534 after NAME, since SunOS /bin/cc can't handle it.
2536 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2538 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2539 From sukes@glue.umd.edu (Tasuki Hirata).
2541 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2543 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2544 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2545 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2547 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2549 * som.c (som_prep_for_fixups): Detect section symbols based
2550 on either the lack of private data or the symbol flags. Do not
2551 munge section symbol names anymore -- they no longer confuse GDB.
2552 (som_begin_writing): Leave space for an exec header if writing
2554 (som_slurp_symbol_table): Recognize both forms of section symbol
2555 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2556 section symbols to be the name of the section they represent.
2557 Debugging symbols begin with "L$0\001", not just "L$".
2559 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2561 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2563 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2564 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2565 and bfd_is_local_label.
2567 * targets.c: Add new entries to the bfd_target structure.

2580 the target vector which all point to bfd_false.
2582 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2583 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2584 Default new vectors for copying private backend data to bfd_true.
2585 Default new vector for determining if a symbol is a local label
2586 to bfd_generic_is_local_label.
2588 * som.c (som_bfd_copy_private_section_data): New function.
2589 (som_bfd_is_local_label): New function.
2590 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2592 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2594 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2596 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2598 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2601 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2602 Indent some of them to GNU standards.
2604 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,

2616 undefined symbols. Correctly distinguish between debugger symbols
2617 and section symbols.

2620 for spaces and subspaces.
2622 * som.c (som_bfd_count_ar_symbols): Fix typo.

2656 cruft (like the #pragma alloca for AIX).
2657 In addition to that problem, the C alloca calls xmalloc, which
