        (elf_link_create_dynamic_sections): If dynamic sections were
4628
        already created, don't do anything.  If dynobj is already set, use

        (elf_i386_create_got_section): New static function.
4646
        (elf_i386_check_relocs): Just call elf_i386_create_got_section if
4647
        a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
4648
        Only create the .rel.got section, and only make space for a reloc,
4649
        for a global symbol or when generating a shared object.  For a

4655
        (elf_i386_size_dynamic_sections): If no dynamic objects were seen,
4656
        skip most of this function, and force the size of the .rel.got

4669
        0x3fffffff.
4670
        (elf32_sparc_create_dynamic_sections): Don't set the size of the
4671
        .plt section.  Call elf32_sparc_create_got_section rather than

        creating the .got section.
4673
        (elf32_sparc_check_relocs): Call elf32_sparc_create_got_section if

        a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.

        Only create the .rela.got section, and only make space for a
4676
        reloc, for a global symbol or when generating a shared object.
4677
        Set the alignment of the .rela.got section to 2.  For a

        (elf32_sparc_adjust_dynamic_symbol): Rework initial assertion to
4680
        permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols.  Create a

4684
        (elf32_sparc_size_dynamic_sections): If no dynamic objects were
4685
        seen, skip most of this function, and force the size of the
4686
        .rela.got section to zero.  Strip empty reloc sections, and strip
4687
        an empty .plt section.
4688
        (elf32_sparc_relocate_section): For a GOT reloc against a global
4689
        symbol when no dynamic object was seen, initialize the contents of
4690
        the .got section.  For a GOT reloc against a local symbol, only
4691
        create a R_SPARC_RELATIVE reloc when generating a shared object.
4692
        Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not

4712
        both were abbreviated "sc" which is (IMHO) clearly unacceptable.

8284
        call to _bfd_generic_link_add_one_symbol.
8285
        (NAME(aout,final_link)): Account for link_order relocs when
8286
        allocating space for relocations.  Handle them after handling all
8287
        input BFDs.
8288
        (aout_link_reloc_link_order): New function.
8289
        * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
8290
        call to _bfd_generic_link_add_one_symbol.
8291
        (ecoff_bfd_final_link): Account for link_order relocs when
8292
        allocating space for relocations.  Handle them in link_order loop.
8293
        (ecoff_link_write_external): Set the storage class of a defined
8294
        linker created symbol based on the section it is in.  Correct
8295
        bfd_link_hash_weak case to use .sc rather than .st.
8296
        (ecoff_reloc_link_order): New function.

8302
        and buf.
8303
 
8304
        * cisco-core.c (cisco_core_file_p): Only pass one argument to

8309
 
8310
        * som.c (som_begin_writing): Fix thinko (off by one error).
8311
 
8312
        * som.c (bfd_section_from_som_symbol): Only to do the value
8313
        comparison for function symbols within executables.
8314
 
8315
        * som.c (bfd_section_from_som_symbol): Renamed from
8316
        som_section_from_subspace_index.  Pass in a native SOM symbol.
8317
        For executables, iterate through the sections to find out
8318
        which contains the symbol's address rather than using the
8319
        symbol_info field.  (symbol_info has a different meaning for
8320
        dynamicly linked executables.)
8321
 
8322
        * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
8323
        bfd_zmalloc.
8324
 
8325
        * som.c (som_begin_writing): Fix braino (one call to align
8326
        space/subspace data was done unconditionally rather than
8327
        just for executables.)
8328
 
8329
        * som.c (som_begin_writing): Align text in all executables to
8330
        make HPUX kernel happy.  Fixes strip/objcopy for shared
8331
        executables.

Sat Mar 19 07:06:59 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
8334
 
8335
        * som.c (som_begin_writing): Account for alignment needs of
8336
        subspaces too when writing executables.  Never request a negative
8337
        bss size.  Fixes some problems with demand paged executables,
8338
        still having problems with pure executables and shared executables.

Fri Mar 18 19:12:47 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
8341
 
8342
        * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
8343
        bfd_zalloc for rawptr, because later on we may call free, not
8344
        bfd_release, on it.
8345
 
8346
        * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
8347
        * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
8348
        * cisco-core.c: New file.
8349
        * Makefile.in: Change accordingly.
8350
        * configure.in: Recognize cisco_core_vec.
8351
        * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

8356
 
8357
        * som.h (som_copyable_section_data_struct): New structure
8358
        containing all the private section information which needs
8359
        to be copied from input section to output section during
8360
        objcopy or strip.
8361
        (som_section_data_struct): Remove several fields now in
8362
        som_copyable_section_data_struct.  Make the space and
8363
        subspace dictionaries be pointers (to save space when
8364
        only reading objects).
8365
 
8366
        * som.c (bfd_som_set_section_attributes): Now returns a boolean;
8367
        some references changed.  Allocate a copyable data stucture if
8368
        none exists.  Store info into the copyable data structure.
8369
        (bfd_som_set_subsection_attributes): Likewise.
8370
        (som_is_space, som_is_subspace, som_is_container): New functions.
8371
        Use these instead of directly accessing private data.
8372
        (som_prep_headers): Allocate space and subspace headers here.
8373
        Fill in some fields in the space/subspace headers from the
8374
        copyable data.
8375
        (som_bfd_copy_private_section_data): Only copy the stuff
8376
        that we really need to make objcopy and strip work.  Allocate
8377
        the copy_data structure for the output bfd before copying.
8378
 
8379
        * som.h (struct som_exec_data): New structure to hold exec
8380
        info that must be preserved when running objcopy/strip.
8381
        (struct somdata): Add new "exec_data" field and accessor
8382
        macro.  Add some comments on how the various fields are used.
8383
        (som_section_data_struct): Make is_space and is_subspace bitfields.
8384
        Delete unused subspace_index.  All references now use the
8385
        target_index field within the section structure itself.
8386
 
8387
        * som.c (make_unique_section): Delete unused declaration.
8388
        (som_bfd_copy_private_bfd_data): New function.
8389
        (som_object_setup): Allocate space for and save exec information
8390
        that needs to be copied during objcopy/strip.
8391
        (som_mkobject): Do not allocate space for a file header here.
8392
        It is not used when only reading SOM objects.
8393
        (som_prep_headers): Allocate space for and attach a file header
8394
        to the output bfd.  For executables, use the saved system_id
8395
        value rather than trying to guess the right value.  Do not abort
8396
        wwhen setting file_hdr->entry* for executables.
8397
        (som_begin_writing): For executables, set the exec_entry and
8398
        exec_flags fields.
8399
        (som_copy_private_backend_section_data): Always return a value.
8400
 
8401
        * libhppa.h (PA_PAGESIZE): Define.
8402
 
8403
        * som.c (SOM_ALIGN): Define.
8404
        (som_begin_writing): If writing an executable, initialize all
8405
        fields in the exec header to zero.  Update fields in the exec
8406
        header as sizes of loadable subspaces are computed.  Carefully
8407
        preserve alignments when building executables.  Actually write the
8408
        exec after all the fields are filled in.
8409
 
8410
        * Better long-filename handling.  Reads SOM ABI compliant extended
8411
        names, but doesn't quite write compliant extended names yet.
8412
        * som.c (som_slurp_extended_name_table): Delete function.  The
8413
        generic code will handle things correctly.
8414
        (som_slurp_armap): Seek to the beginning of the next member.
8415
        (normalize): New function.
8416
        (som_bfd_ar_write_symbol_stuff): Take the size of the extended
8417
        name table into account when computing the file offsets in the
8418
        SOM dictionary.  Make sure to align to an even boundary.
8419
        (som_write_armap): Initialize the checksum to zero.
8420
        (ar_maxchars): Fix.  Opps.

8423
 
8424
        * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
8425
        machine.  Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
8426

Thu Mar 17 18:26:46 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)
8428
 
8429
        * bfd-in.h (BFD_VERSION): Use @VERSION@.
8430
        * Makefile.in (bfd.h): Replace it with contents of VERSION file.
8431
        * bfd-in2.h: Regenerated.
8432
 
8433
        * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
8434
        this was also named trad_unix_bfd_copy_private_bfd_data.
8435
 
8436
Thu Mar 17 10:37:07 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
8437
 
8438
        * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
8439
        elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
8440
        returns NULL, it is not an error.  It's possible that some of
8441
        these checks are not necessary (because the size can never be
8442
        zero), but putting in the checks is the conservative thing to do
8443
        in light of the fact that some of these malloc calls replaced
8444
        unchecked alloca calls, in which a zero argument would work fine.
8445

Thu Mar 17 11:44:45 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

8449
        duplicate definition.
8450
        (osf_core_bfd_is_local_label): Define.
8451
 
8452
        * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
8453
        if malloc (0) fails.  bfd_canonicalize_reloc returning 0 is not a
8454
        failure indication, it merely means there are no relocs.
8455
 
8456
        * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
8457
        after NAME, since SunOS /bin/cc can't handle it.
8458

Wed Mar 16 07:55:54 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
8465
 
8466
        * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
8467
        all that convoluted stuff with NAME, CAT3, etc.  The convoluted
8468
        stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

8471
 
8472
        * som.c (som_prep_for_fixups): Detect section symbols based
8473
        on either the lack of private data or the symbol flags.  Do not
8474
        munge section symbol names anymore -- they no longer confuse GDB.
8475
        (som_begin_writing): Leave space for an exec header if writing
8476
        an executable.
8477
        (som_slurp_symbol_table): Recognize both forms of section symbol
8478
        names "L$0\002" and "$$".  Change the name of "L$0\002"
8479
        section symbols to be the name of the section they represent.
8480
        Debugging  symbols begin with "L$0\001", not just "L$".

8534
 
8535
        * som.c (som_prep_for_fixups): A relocation involving the section
8536
        symbol for the *ABS* section is really a relocation involving
8537
        no symbol.
8538
        (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
8539
        undefined symbols.  Correctly distinguish between debugger symbols
8540
        and section symbols.
8541
 
8542
        * som.c (setup_sections): Set SEC_DEBUGGING and the section attributes
8543
        for spaces and subspaces.
8544

        * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
8548
        HAS_RELOC based on the object's magic number.
8549
        (make_unique_section): Delete function.  BFD and its users are
8550
        prepared to handle multiple sections with the same name.
8551
        (setup_sections): Allocate space on the BFD's obstack to hold
8552
        section names.  Use bfd_make_setion_anyway rather than the
8553
        obsolete make_unique_section.
8554

8578
        * libbfd-in.h: Remove alloca cruft.  It was missing some necessary
8579
        cruft (like the #pragma alloca for AIX).
8580
        In addition to that problem, the C alloca calls xmalloc, which
8581
        means checking for being out of memory can't work right.  The
8582
        following changes remove all uses of alloca from BFD.

8614
        return from bfd_seek indicates an error.
8615
        New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
8616
        TRAD_CORE_STACK_OFFSET.
8617

8918
 
8919
        * section.c (bfd_get_section_contents): Since this function reads

8923
        * linker.c (default_indirect_link_order): In assertion, compare

        return 0.
8929
        (aligncode): When shrinking, the addend should be set to the
8930

        properly ordered.
8937
        (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
8938

        raw size of the input section.
8940
 
8941
        * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
8942
        bout.  Default with no version number is still bout.  Support
8943
        explicit i960-coff target too.
8944
 
8945
        * bout.c: Changed some indentation, deleted trailing whitespace,

9017
 
9018
        Make all callers of malloc or realloc (including via obstacks)
9019
        check the result for NULL.  Most set bfd_error to no_memory and
9020

9469
        Don't print out "pagesize =" line that prevents output from

        in the backend accessor macros; that should no longer be possible.

10021
        * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
10022
