3455 relocs when allocating space for relocations. Set SEC_RELOC flag
3456 for any section which has relocs. Handle link_order relocs in
3457 link_order loop. Use _bfd_generic_link_add_symbols_collect for
3458 add_symbls entry point.
3460 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
3461 counting relocs. Set SEC_RELOC flag for any section which has
3464 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
3466 * linker.c (_bfd_generic_link_add_symbols): Just call
3467 generic_link_add_symbols.
3468 (_bfd_generic_link_add_symbols_collect): New function, like
3469 _bfd_generic_link_add_symbols but also collect constructors and
3470 destructors by name as collect2 does.
3471 (generic_link_add_symbols): New function, like old
3472 _bfd_generic_link_add_symbols but with collect argument.
3473 (generic_link_add_object_symbols): Take collect argument.

3485 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
3486 for first character in an extended name.
3487 (_bfd_write_archive_contents): If ar_padchar == '/', then use
3488 "//" as the name of the special archive member holding the
3489 extended name table.
3491 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3493 Support for link_order types which generate relocs in order to
3494 support -Ur in the linker.
3495 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3496 from call to _bfd_generic_link_add_one_symbol.
3497 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3498 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
3499 instead of bitsize to add_to_set call back.
3500 (_bfd_generic_final_link): Account for link_order relocs when
3501 allocating space for relocations. Handle them in link_order loop.
3502 (_bfd_generic_reloc_link_order): New function.
3503 (_bfd_default_link_order): If a reloc_link_order is seen here,
3505 (_bfd_count_link_order_relocs): New function.
3506 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
3507 argument from declaration.
3508 (_bfd_generic_reloc_link_order): Declare.
3509 (_bfd_count_link_order_relocs): Declare.
3510 * libbfd.h: Rebuilt.
3511 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
3512 call to _bfd_generic_link_add_one_symbol.
3513 (NAME(aout,final_link)): Account for link_order relocs when

3518 call to _bfd_generic_link_add_one_symbol.
3519 (ecoff_bfd_final_link): Account for link_order relocs when
3520 allocating space for relocations. Handle them in link_order loop.
3521 (ecoff_link_write_external): Set the storage class of a defined
3522 linker created symbol based on the section it is in. Correct
3523 bfd_link_hash_weak case to use .sc rather than .st.
3524 (ecoff_reloc_link_order): New function.
3525 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
3527 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
3529 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
3532 * cisco-core.c (cisco_core_file_p): Only pass one argument to
3533 bfd_zmalloc. Free a pointer, not a union.
3534 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
3536 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3538 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
3540 * som.c (bfd_section_from_som_symbol): Only to do the value
3541 comparison for function symbols within executables.
3543 * som.c (bfd_section_from_som_symbol): Renamed from
3544 som_section_from_subspace_index. Pass in a native SOM symbol.
3545 For executables, iterate through the sections to find out
3546 which contains the symbol's address rather than using the
3547 symbol_info field. (symbol_info has a different meaning for
3548 dynamicly linked executables.)
3550 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3553 * som.c (som_begin_writing): Fix braino (one call to align
3554 space/subspace data was done unconditionally rather than
3555 just for executables.)
3557 * som.c (som_begin_writing): Align text in all executables to
3558 make HPUX kernel happy. Fixes strip/objcopy for shared
3561 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3563 * som.c (som_begin_writing): Account for alignment needs of
3564 subspaces too when writing executables. Never request a negative
3565 bss size. Fixes some problems with demand paged executables,
3566 still having problems with pure executables and shared executables.
3568 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3570 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3571 bfd_zalloc for rawptr, because later on we may call free, not
3574 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3575 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3576 * cisco-core.c: New file.
3577 * Makefile.in: Change accordingly.
3578 * configure.in: Recognize cisco_core_vec.
3579 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3580 * targets.c: Add cisco_core_vec.
3581 * bfd-in2.h: Rebuilt.
3583 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3585 * som.h (som_copyable_section_data_struct): New structure
3586 containing all the private section information which needs
3587 to be copied from input section to output section during
3589 (som_section_data_struct): Remove several fields now in
3590 som_copyable_section_data_struct. Make the space and
3591 subspace dictionaries be pointers (to save space when
3592 only reading objects).
3594 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3595 some references changed. Allocate a copyable data stucture if
3596 none exists. Store info into the copyable data structure.
3597 (bfd_som_set_subsection_attributes): Likewise.
3598 (som_is_space, som_is_subspace, som_is_container): New functions.
3599 Use these instead of directly accessing private data.
3600 (som_prep_headers): Allocate space and subspace headers here.
3601 Fill in some fields in the space/subspace headers from the
3603 (som_bfd_copy_private_section_data): Only copy the stuff
3604 that we really need to make objcopy and strip work. Allocate
3605 the copy_data structure for the output bfd before copying.
3607 * som.h (struct som_exec_data): New structure to hold exec
3608 info that must be preserved when running objcopy/strip.
3609 (struct somdata): Add new "exec_data" field and accessor
3610 macro. Add some comments on how the various fields are used.
3611 (som_section_data_struct): Make is_space and is_subspace bitfields.
3612 Delete unused subspace_index. All references now use the
3613 target_index field within the section structure itself.
3615 * som.c (make_unique_section): Delete unused declaration.
3616 (som_bfd_copy_private_bfd_data): New function.
3617 (som_object_setup): Allocate space for and save exec information
3618 that needs to be copied during objcopy/strip.
3619 (som_mkobject): Do not allocate space for a file header here.
3620 It is not used when only reading SOM objects.
3621 (som_prep_headers): Allocate space for and attach a file header
3622 to the output bfd. For executables, use the saved system_id
3623 value rather than trying to guess the right value. Do not abort
3624 wwhen setting file_hdr->entry* for executables.
3625 (som_begin_writing): For executables, set the exec_entry and
3627 (som_copy_private_backend_section_data): Always return a value.
3629 * libhppa.h (PA_PAGESIZE): Define.
3631 * som.c (SOM_ALIGN): Define.
3632 (som_begin_writing): If writing an executable, initialize all
3633 fields in the exec header to zero. Update fields in the exec
3634 header as sizes of loadable subspaces are computed. Carefully
3635 preserve alignments when building executables. Actually write the
3636 exec after all the fields are filled in.
3638 * Better long-filename handling. Reads SOM ABI compliant extended
3639 names, but doesn't quite write compliant extended names yet.
3640 * som.c (som_slurp_extended_name_table): Delete function. The
3641 generic code will handle things correctly.
3642 (som_slurp_armap): Seek to the beginning of the next member.
3643 (normalize): New function.
3644 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3645 name table into account when computing the file offsets in the
3646 SOM dictionary. Make sure to align to an even boundary.
3647 (som_write_armap): Initialize the checksum to zero.
3648 (ar_maxchars): Fix. Opps.
3650 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3652 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3653 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3655 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3657 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3658 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3659 * bfd-in2.h: Regenerated.
3661 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3662 this was also named trad_unix_bfd_copy_private_bfd_data.
3664 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3666 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3667 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3668 returns NULL, it is not an error. It's possible that some of
3669 these checks are not necessary (because the size can never be
3670 zero), but putting in the checks is the conservative thing to do
3671 in light of the fact that some of these malloc calls replaced
3672 unchecked alloca calls, in which a zero argument would work fine.
3674 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3676 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3677 duplicate definition.
3678 (osf_core_bfd_is_local_label): Define.
3680 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3681 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3682 failure indication, it merely means there are no relocs.
3684 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3685 after NAME, since SunOS /bin/cc can't handle it.
3687 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3689 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3690 From sukes@glue.umd.edu (Tasuki Hirata).
3692 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3694 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3695 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3696 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3698 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3700 * som.c (som_prep_for_fixups): Detect section symbols based
3701 on either the lack of private data or the symbol flags. Do not
3702 munge section symbol names anymore -- they no longer confuse GDB.
3703 (som_begin_writing): Leave space for an exec header if writing
3705 (som_slurp_symbol_table): Recognize both forms of section symbol
3706 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3707 section symbols to be the name of the section they represent.
3708 Debugging symbols begin with "L$0\001", not just "L$".
3710 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3712 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3714 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3715 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3716 and bfd_is_local_label.
3718 * targets.c: Add new entries to the bfd_target structure.
3720 * bfd.c (bfd_copy_private_bfd_data): New definition.
3722 * section.c (bfd_copy_private_section_data): New definition.
3724 * syms.c (bfd_is_local_label): New definition.
3726 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3728 * libbfd.c (bfd_generic_is_local_label): New function.
3730 * *-core.c: Provide default definitions for new functions in
3731 the target vector which all point to bfd_false.
3733 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3734 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3735 Default new vectors for copying private backend data to bfd_true.
3736 Default new vector for determining if a symbol is a local label
3737 to bfd_generic_is_local_label.
3739 * som.c (som_bfd_copy_private_section_data): New function.
3740 (som_bfd_is_local_label): New function.
3741 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3743 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3745 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3747 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3749 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3752 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3753 Indent some of them to GNU standards.
3755 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3756 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3757 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3758 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3759 Update copyright years.
3761 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3763 * som.c (som_prep_for_fixups): A relocation involving the section
3764 symbol for the *ABS* section is really a relocation involving
3766 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3767 undefined symbols. Correctly distinguish between debugger symbols
3768 and section symbols.
3770 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3771 for spaces and subspaces.
3773 * som.c (som_bfd_count_ar_symbols): Fix typo.
3775 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3776 HAS_RELOC based on the object's magic number.
3777 (make_unique_section): Delete function. BFD and its users are
3778 prepared to handle multiple sections with the same name.
3779 (setup_sections): Allocate space on the BFD's obstack to hold
3780 section names. Use bfd_make_setion_anyway rather than the
3781 obsolete make_unique_section.
3782 (som_prep_headers): Choose the correct SOM magic number based
3784 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3786 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3788 * elf32-ppc.c: Renamed from elf32-powerpc.c.

3798 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3799 is always located at the start of the data section to allow
3800 recovery of the dynamic info from a stripped executable.
3801 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3804 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3806 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3807 cruft (like the #pragma alloca for AIX).
3808 In addition to that problem, the C alloca calls xmalloc, which
3809 means checking for being out of memory can't work right. The
3810 following changes remove all uses of alloca from BFD.
3811 * hosts/solaris2.h: Remove alloca cruft.
3812 * som.c: Replace alloca with a fixed size auto array.

3820 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3822 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3825 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3827 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3828 Elf*_Off typedefs by their expansion, the typedefs have been
3829 removed from include/elf/internal.h.
3830 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3831 SHT_PROGBITS section.
3833 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3835 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3839 * configure.host: Recognize i[34]86-sequent-*.
3841 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3842 return from bfd_seek indicates an error.
3843 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3844 TRAD_CORE_STACK_OFFSET.
3845 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3846 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3848 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3850 * som.[ch]: Do not include libhppa.h in som.c, instead include
3853 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3854 include it in elf32-hppa.h.
3856 * som.c (log2): Return -1 on error rather than aborting.
3857 (setup_sections): Bubble up an error from log2.
3859 * Changes to make HP C compiler happy in both traditional
3861 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3863 (bfd_som_set_section_attributes): Use unsigned int rather than
3864 unsigned char to avoid GNU-C extensions.
3865 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3866 or failure rather than aborting on failure.
3868 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3870 (bfd_som_attach_aux_hdr): Add prototype.
3871 (hppa_som-gen_reloc_type): Likewise.

3874 (hppa_look_for_stubs_in_section): Do not return false on failure
3875 until rest of code is ready to handle it. Abort for now.
3877 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3879 * bfd-in2.h: Rebuilt.
3881 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

3900 action in case where caller specified no argument relocation.
3901 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3902 right in the original relocation and the stub's relocation.

3935 #defines for lots of things. Merge two functions which build
3936 linker stubs into a single function (so they can easily share a

3985 COMPLEX relocation support (it's never used anyway).
3986 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3987 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).

4160 (b_out_relax_section): If a section contains no relocations, don't
4161 bother processing them.
4162 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4866 way to write exports, so add a write_export field to the backend
4867 data (and set it to NULL for everything but the sparc).

6106 time though if output sections exist (fixes ld -r problems).
6108 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)
6110 * Makefile.in: Add .PHONY for check and installcheck rules.
6112 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
6114 * libbfd-in.h (artdata): Use long, not time_t for portability, at
6115 least to HPUX. File below is a derived file.

6119 * libbfd.h (artdata): Use long, not time_t for portability, at
6122 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
6124 * config.bfd: Use bigmips for mips*-*-bsd*.
6126 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6128 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
6129 Handle symbol number of zero.
6131 * reloc.c (enum bfd_reloc_code_real): Added
6132 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
6133 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
6134 * bfd-in2.h: Rebuilt.
6135 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
6136 BFD_RELOC_MIPS_LITERAL.
6137 * elf32-mips.c (mips_reloc_map): Handle new relocs.
6138 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
6141 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
6142 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
6143 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
6144 MY_bfd_seclet_link): Define.
6145 (MY_bfd_reloc_type_lookup): Rename from
6146 MY_reloc_howto_type_lookup.
6147 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
6148 (MY(vec)): Use JUMP_TABLE rather than listing functions.
6149 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
6150 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
6151 terms of MY, because that causes a recusive invocation of CAT when
6152 expanded within JUMP_TABLE, and ANSI compilers don't expand
6154 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6155 MY_reloc_howto_type_lookup, and don't define in terms of MY.
6156 (MY_canonicalize_reloc): Don't define in terms of MY.
6157 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
6158 than listing functions.
