2200 in executables left by the HP linker. Does not rely on subspace
2201 alignments as subspaces are *NOT* guaranteed to be properly

2204 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2206 * som.c (som_get_section_contents): New function. Do not try

2252 required by expansions. Set s and unset h when converting a reloc
2253 from undefined to section. Change handling of PC relative relocs:
2254 if against a section, they are correct in the object file, if
2255 against an external symbol they are pcrel_offset.
2256 (mips_relax_section): New function.
2257 (mips_relax_pcrel16): New function.
2258 (ecoff_bfd_relax_section): Define.

2343 reloc, used in embedded PIC code.
2344 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2352 add_symbls entry point.
2354 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2355 counting relocs. Set SEC_RELOC flag for any section which has

2383 extended name table.
2385 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2387 Support for link_order types which generate relocs in order to
2388 support -Ur in the linker.
2389 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2390 from call to _bfd_generic_link_add_one_symbol.
2391 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2392 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2393 instead of bitsize to add_to_set call back.
2394 (_bfd_generic_final_link): Account for link_order relocs when
2395 allocating space for relocations. Handle them in link_order loop.
2396 (_bfd_generic_reloc_link_order): New function.

2414 allocating space for relocations. Handle them in link_order loop.
2415 (ecoff_link_write_external): Set the storage class of a defined
2416 linker created symbol based on the section it is in. Correct
2417 bfd_link_hash_weak case to use .sc rather than .st.
2418 (ecoff_reloc_link_order): New function.
2419 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

2430 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2432 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2434 * som.c (bfd_section_from_som_symbol): Only to do the value
2435 comparison for function symbols within executables.
2437 * som.c (bfd_section_from_som_symbol): Renamed from
2438 som_section_from_subspace_index. Pass in a native SOM symbol.
2439 For executables, iterate through the sections to find out
2440 which contains the symbol's address rather than using the
2441 symbol_info field. (symbol_info has a different meaning for
2442 dynamicly linked executables.)
2444 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2447 * som.c (som_begin_writing): Fix braino (one call to align
2448 space/subspace data was done unconditionally rather than
2449 just for executables.)
2451 * som.c (som_begin_writing): Align text in all executables to
2452 make HPUX kernel happy. Fixes strip/objcopy for shared
2455 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2457 * som.c (som_begin_writing): Account for alignment needs of
2458 subspaces too when writing executables. Never request a negative
2459 bss size. Fixes some problems with demand paged executables,
2460 still having problems with pure executables and shared executables.
2462 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2464 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2465 bfd_zalloc for rawptr, because later on we may call free, not
2468 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2469 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2470 * cisco-core.c: New file.
2471 * Makefile.in: Change accordingly.
2472 * configure.in: Recognize cisco_core_vec.
2473 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2474 * targets.c: Add cisco_core_vec.
2475 * bfd-in2.h: Rebuilt.
2477 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2479 * som.h (som_copyable_section_data_struct): New structure
2480 containing all the private section information which needs
2481 to be copied from input section to output section during
2483 (som_section_data_struct): Remove several fields now in
2484 som_copyable_section_data_struct. Make the space and
2485 subspace dictionaries be pointers (to save space when
2486 only reading objects).
2488 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2489 some references changed. Allocate a copyable data stucture if
2490 none exists. Store info into the copyable data structure.
2491 (bfd_som_set_subsection_attributes): Likewise.
2492 (som_is_space, som_is_subspace, som_is_container): New functions.
2493 Use these instead of directly accessing private data.
2494 (som_prep_headers): Allocate space and subspace headers here.
2495 Fill in some fields in the space/subspace headers from the
2497 (som_bfd_copy_private_section_data): Only copy the stuff
2498 that we really need to make objcopy and strip work. Allocate
2499 the copy_data structure for the output bfd before copying.
2501 * som.h (struct som_exec_data): New structure to hold exec
2502 info that must be preserved when running objcopy/strip.
2503 (struct somdata): Add new "exec_data" field and accessor
2504 macro. Add some comments on how the various fields are used.
2505 (som_section_data_struct): Make is_space and is_subspace bitfields.
2506 Delete unused subspace_index. All references now use the
2507 target_index field within the section structure itself.
2509 * som.c (make_unique_section): Delete unused declaration.
2510 (som_bfd_copy_private_bfd_data): New function.
2511 (som_object_setup): Allocate space for and save exec information
2512 that needs to be copied during objcopy/strip.
2513 (som_mkobject): Do not allocate space for a file header here.
2514 It is not used when only reading SOM objects.
2515 (som_prep_headers): Allocate space for and attach a file header
2516 to the output bfd. For executables, use the saved system_id
2517 value rather than trying to guess the right value. Do not abort
2518 wwhen setting file_hdr->entry* for executables.
2519 (som_begin_writing): For executables, set the exec_entry and
2521 (som_copy_private_backend_section_data): Always return a value.
2523 * libhppa.h (PA_PAGESIZE): Define.
2525 * som.c (SOM_ALIGN): Define.
2526 (som_begin_writing): If writing an executable, initialize all
2527 fields in the exec header to zero. Update fields in the exec
2528 header as sizes of loadable subspaces are computed. Carefully
2529 preserve alignments when building executables. Actually write the
2530 exec after all the fields are filled in.
2532 * Better long-filename handling. Reads SOM ABI compliant extended
2533 names, but doesn't quite write compliant extended names yet.
2534 * som.c (som_slurp_extended_name_table): Delete function. The
2535 generic code will handle things correctly.
2536 (som_slurp_armap): Seek to the beginning of the next member.
2537 (normalize): New function.
2538 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2539 name table into account when computing the file offsets in the
2540 SOM dictionary. Make sure to align to an even boundary.
2541 (som_write_armap): Initialize the checksum to zero.
2542 (ar_maxchars): Fix. Opps.
2544 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2546 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2547 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2549 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2551 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2552 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2553 * bfd-in2.h: Regenerated.
2555 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2556 this was also named trad_unix_bfd_copy_private_bfd_data.
2558 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2560 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2561 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2562 returns NULL, it is not an error. It's possible that some of
2563 these checks are not necessary (because the size can never be
2564 zero), but putting in the checks is the conservative thing to do
2565 in light of the fact that some of these malloc calls replaced
2566 unchecked alloca calls, in which a zero argument would work fine.
2568 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2570 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2571 duplicate definition.
2572 (osf_core_bfd_is_local_label): Define.
2574 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2575 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2576 failure indication, it merely means there are no relocs.
2578 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2579 after NAME, since SunOS /bin/cc can't handle it.
2581 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2583 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2584 From sukes@glue.umd.edu (Tasuki Hirata).
2586 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2588 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2589 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2590 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2592 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2594 * som.c (som_prep_for_fixups): Detect section symbols based
2595 on either the lack of private data or the symbol flags. Do not
2596 munge section symbol names anymore -- they no longer confuse GDB.

3543 _bfd_generic_link_write_global_symbol): Don't require that all
3544 references to a common symbol be themselves common symbols.

3732 undefined, look it up in the linker hash table.
3734 * aoutx.h (translate_symbol_table): The string index 0 has a

3759 The sparc (and possibly other?) NLM format requires a different
3760 way to write exports, so add a write_export field to the backend
3761 data (and set it to NULL for everything but the sparc).
