3 Fix the ELF linker to not require an interpreter if no dynamic
4 objects were seen, even when linking PIC code.
5 * libelf.h (ELF_LINK_HASH_NEEDS_PLT): Define.
6 (struct elf_link_hash_table): Add field dynamic_sections_created.
7 * elfcode.h (elf_link_record_dynamic_symbol): Create dynstr if it
9 (elf_link_add_object_symbols): Create dynamic sections based on
10 dynamic_sections_created field, not dynobj field. Don't bother to
12 (elf_link_create_dynamic_sections): If dynamic sections were
13 already created, don't do anything. If dynobj is already set, use
14 it; otherwise, set it to the bfd argument. Don't initialize
15 dynsymcount. Only create dynstr if it does not exist. Set
16 dynamic_sections_created to true.
17 (NAME(bfd_elf,size_dynamic_sections)): Skip most of this function
18 if no dynamic objects were seen.
19 (elf_adjust_dynamic_symbol): If a symbol has the
20 ELF_LINK_HASH_NEEDS_PLT flag set, let the backend adjust it.
21 (elf_bfd_final_link): Change most decisions based on dynobj to
22 check dynamic_sections_created instead.
23 (elf_link_output_extsym): Only handle dynamic symbols if a dynamic
25 * elf.c (_bfd_elf_link_hash_table_init): Initialize new field
26 dynamic_sections_created. Set dynsymcount to 1, not 0.
27 * elf32-i386.c (elf_i386_create_dynamic_sections): Call
28 elf_i386_create_got_section rather than creating the .got and
30 (elf_i386_create_got_section): New static function.
31 (elf_i386_check_relocs): Just call elf_i386_create_got_section if
32 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
33 Only create the .rel.got section, and only make space for a reloc,
34 for a global symbol or when generating a shared object. For a
35 R_386_PLT32 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
36 (elf_i386_adjust_dynamic_symbol): Rework initial assertion to
37 permit ELF_LINK_HASH_NEEDS_PLT non dynamic symbols. Create a
38 procedure linkage table entry for such symbols. But, if no
39 dynamic objects were seen, never create a PLT entry.
40 (elf_i386_size_dynamic_sections): If no dynamic objects were seen,
41 skip most of this function, and force the size of the .rel.got
43 (elf_i386_relocate_section): For a R_386_GOT32 reloc against a global
44 symbol when no dynamic object was seen, initialize the contents of
45 the .got section. For a R_386_GOT32 against a local symbol, only
46 create a R_386_RELATIVE reloc when generating a shared object.
47 Treat a R_386_PLT32 reloc against a symbol for which we did not
48 create a PLT entry as a R_386_PC32 reloc.
49 (elf_i386_finish_dynamic_sections): Only fiddle with the dynamic
50 entries and the PLT if we saw a dynamic object.
51 * elf32-sparc.c (elf_sparc_howto_table): Fix R_SPARC_PC22 by
52 setting rightshift to 10. Fix R_SPARC_WPLT20 by setting
53 rightshift to 2, size to 2, bitsize to 30, and dst_mask to
55 (elf32_sparc_create_dynamic_sections): Don't set the size of the
56 .plt section. Call elf32_sparc_create_got_section rather than
57 creating the .got section.
58 (elf32_sparc_check_relocs): Call elf32_sparc_create_got_section if
59 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
60 Only create the .rela.got section, and only make space for a
61 reloc, for a global symbol or when generating a shared object.
62 Set the alignment of the .rela.got section to 2. For a
63 R_SPARC_WPLT30 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
64 (elf32_sparc_adjust_dynamic_symbol): Rework initial assertion to
65 permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols. Create a
66 procedure linkage table for such symbols. But, if no dynamic
67 objects were seen, never create a PLT entry. Initialize the size
69 (elf32_sparc_size_dynamic_sections): If no dynamic objects were
70 seen, skip most of this function, and force the size of the
71 .rela.got section to zero. Strip empty reloc sections, and strip
72 an empty .plt section.
73 (elf32_sparc_relocate_section): For a GOT reloc against a global
74 symbol when no dynamic object was seen, initialize the contents of
75 the .got section. For a GOT reloc against a local symbol, only
76 create a R_SPARC_RELATIVE reloc when generating a shared object.
77 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
78 create a PLT entry as a R_SPARC_WDISP30 reloc.
79 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
80 dynamic entries and the PLT if we saw a dynamic object.

87 backend routine. Check bfd_section and call the backend routine
88 even for a section not owned by any BFD.
89 * elf32-mips.c (mips_elf_section_from_bfd_section): Handle

94 * coffgen.c (coff_print_symbol): Make names for section number and
95 storage class slightly more verbose. It's not clear how many
96 characters I can justify using up, but before this change they
97 both were abbreviated "sc" which is (IMHO) clearly unacceptable.

3464 * som.c (som_begin_writing): New approach at dealing with holes
3465 in executables left by the HP linker. Does not rely on subspace
3466 alignments as subspaces are *NOT* guaranteed to be properly
3467 aligned in an executable (can you believe that!).
3469 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3471 * som.c (som_get_section_contents): New function. Do not try

3517 required by expansions. Set s and unset h when converting a reloc
3518 from undefined to section. Change handling of PC relative relocs:
3519 if against a section, they are correct in the object file, if
3520 against an external symbol they are pcrel_offset.
3521 (mips_relax_section): New function.
3522 (mips_relax_pcrel16): New function.
3523 (ecoff_bfd_relax_section): Define.

3608 reloc, used in embedded PIC code.
3609 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
3610 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

3616 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3617 add_symbls entry point.
3619 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3620 counting relocs. Set SEC_RELOC flag for any section which has

3648 extended name table.
3650 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3652 Support for link_order types which generate relocs in order to
3653 support -Ur in the linker.
3654 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3655 from call to _bfd_generic_link_add_one_symbol.
3656 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3657 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3658 instead of bitsize to add_to_set call back.
3659 (_bfd_generic_final_link): Account for link_order relocs when
3660 allocating space for relocations. Handle them in link_order loop.
3661 (_bfd_generic_reloc_link_order): New function.

3678 (ecoff_bfd_final_link): Account for link_order relocs when
3679 allocating space for relocations. Handle them in link_order loop.
3680 (ecoff_link_write_external): Set the storage class of a defined
3681 linker created symbol based on the section it is in. Correct
3682 bfd_link_hash_weak case to use .sc rather than .st.
3683 (ecoff_reloc_link_order): New function.
3684 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3686 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

3692 bfd_zmalloc. Free a pointer, not a union.
3693 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3695 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3697 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3699 * som.c (bfd_section_from_som_symbol): Only to do the value
3700 comparison for function symbols within executables.
3702 * som.c (bfd_section_from_som_symbol): Renamed from
3703 som_section_from_subspace_index. Pass in a native SOM symbol.
3704 For executables, iterate through the sections to find out
3705 which contains the symbol's address rather than using the
3706 symbol_info field. (symbol_info has a different meaning for
3707 dynamicly linked executables.)
3709 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3712 * som.c (som_begin_writing): Fix braino (one call to align
3713 space/subspace data was done unconditionally rather than
3714 just for executables.)
3716 * som.c (som_begin_writing): Align text in all executables to
3717 make HPUX kernel happy. Fixes strip/objcopy for shared
3720 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3722 * som.c (som_begin_writing): Account for alignment needs of
3723 subspaces too when writing executables. Never request a negative
3724 bss size. Fixes some problems with demand paged executables,
3725 still having problems with pure executables and shared executables.
3727 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3729 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3730 bfd_zalloc for rawptr, because later on we may call free, not
3733 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3734 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3735 * cisco-core.c: New file.
3736 * Makefile.in: Change accordingly.
3737 * configure.in: Recognize cisco_core_vec.
3738 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3739 * targets.c: Add cisco_core_vec.
3740 * bfd-in2.h: Rebuilt.
3742 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3744 * som.h (som_copyable_section_data_struct): New structure
3745 containing all the private section information which needs
3746 to be copied from input section to output section during
3748 (som_section_data_struct): Remove several fields now in
3749 som_copyable_section_data_struct. Make the space and
3750 subspace dictionaries be pointers (to save space when
3751 only reading objects).
3753 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3754 some references changed. Allocate a copyable data stucture if
3755 none exists. Store info into the copyable data structure.
3756 (bfd_som_set_subsection_attributes): Likewise.
3757 (som_is_space, som_is_subspace, som_is_container): New functions.
3758 Use these instead of directly accessing private data.
3759 (som_prep_headers): Allocate space and subspace headers here.
3760 Fill in some fields in the space/subspace headers from the
3762 (som_bfd_copy_private_section_data): Only copy the stuff
3763 that we really need to make objcopy and strip work. Allocate
3764 the copy_data structure for the output bfd before copying.
3766 * som.h (struct som_exec_data): New structure to hold exec
3767 info that must be preserved when running objcopy/strip.
3768 (struct somdata): Add new "exec_data" field and accessor
3769 macro. Add some comments on how the various fields are used.
3770 (som_section_data_struct): Make is_space and is_subspace bitfields.
3771 Delete unused subspace_index. All references now use the
3772 target_index field within the section structure itself.
3774 * som.c (make_unique_section): Delete unused declaration.
3775 (som_bfd_copy_private_bfd_data): New function.
3776 (som_object_setup): Allocate space for and save exec information
3777 that needs to be copied during objcopy/strip.
3778 (som_mkobject): Do not allocate space for a file header here.
3779 It is not used when only reading SOM objects.
3780 (som_prep_headers): Allocate space for and attach a file header
3781 to the output bfd. For executables, use the saved system_id
3782 value rather than trying to guess the right value. Do not abort
3783 wwhen setting file_hdr->entry* for executables.
3784 (som_begin_writing): For executables, set the exec_entry and
3786 (som_copy_private_backend_section_data): Always return a value.
3788 * libhppa.h (PA_PAGESIZE): Define.
3790 * som.c (SOM_ALIGN): Define.
3791 (som_begin_writing): If writing an executable, initialize all
3792 fields in the exec header to zero. Update fields in the exec
3793 header as sizes of loadable subspaces are computed. Carefully
3794 preserve alignments when building executables. Actually write the
3795 exec after all the fields are filled in.
3797 * Better long-filename handling. Reads SOM ABI compliant extended
3798 names, but doesn't quite write compliant extended names yet.
3799 * som.c (som_slurp_extended_name_table): Delete function. The
3800 generic code will handle things correctly.
3801 (som_slurp_armap): Seek to the beginning of the next member.
3802 (normalize): New function.
3803 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3804 name table into account when computing the file offsets in the
3805 SOM dictionary. Make sure to align to an even boundary.
3806 (som_write_armap): Initialize the checksum to zero.
3807 (ar_maxchars): Fix. Opps.
3809 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3811 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3812 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3814 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3816 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3817 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3818 * bfd-in2.h: Regenerated.
3820 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3821 this was also named trad_unix_bfd_copy_private_bfd_data.
3823 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3825 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3826 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3827 returns NULL, it is not an error. It's possible that some of
3828 these checks are not necessary (because the size can never be
3829 zero), but putting in the checks is the conservative thing to do
3830 in light of the fact that some of these malloc calls replaced
3831 unchecked alloca calls, in which a zero argument would work fine.
3833 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3835 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3836 duplicate definition.
3837 (osf_core_bfd_is_local_label): Define.
3839 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3840 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3841 failure indication, it merely means there are no relocs.
3843 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3844 after NAME, since SunOS /bin/cc can't handle it.
3846 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3848 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3849 From sukes@glue.umd.edu (Tasuki Hirata).
3851 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3853 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3854 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3855 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3857 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3859 * som.c (som_prep_for_fixups): Detect section symbols based
3860 on either the lack of private data or the symbol flags. Do not
3861 munge section symbol names anymore -- they no longer confuse GDB.
3862 (som_begin_writing): Leave space for an exec header if writing
3864 (som_slurp_symbol_table): Recognize both forms of section symbol
3865 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3866 section symbols to be the name of the section they represent.
3867 Debugging symbols begin with "L$0\001", not just "L$".
3869 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3871 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3873 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3874 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3875 and bfd_is_local_label.

3966 cruft (like the #pragma alloca for AIX).
3967 In addition to that problem, the C alloca calls xmalloc, which

4886 bfd_som_set_subsection_attributes): Change parameters from char
4887 to int. Following a prototype with an old-style function definition

4997 undefined, look it up in the linker hash table.
4999 * aoutx.h (translate_symbol_table): The string index 0 has a

5024 The sparc (and possibly other?) NLM format requires a different
5025 way to write exports, so add a write_export field to the backend
5026 data (and set it to NULL for everything but the sparc).
