3463 * som.c (som_begin_writing): Align text in all executables to
3464 make HPUX kernel happy. Fixes strip/objcopy for shared
3467 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3469 * som.c (som_begin_writing): Account for alignment needs of
3470 subspaces too when writing executables. Never request a negative
3471 bss size. Fixes some problems with demand paged executables,
3472 still having problems with pure executables and shared executables.
3474 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3476 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
3477 bfd_zalloc for rawptr, because later on we may call free, not
3480 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
3481 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
3482 * cisco-core.c: New file.
3483 * Makefile.in: Change accordingly.
3484 * configure.in: Recognize cisco_core_vec.
3485 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
3486 * targets.c: Add cisco_core_vec.
3487 * bfd-in2.h: Rebuilt.
3489 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3491 * som.h (som_copyable_section_data_struct): New structure
3492 containing all the private section information which needs
3493 to be copied from input section to output section during
3495 (som_section_data_struct): Remove several fields now in
3496 som_copyable_section_data_struct. Make the space and
3497 subspace dictionaries be pointers (to save space when
3498 only reading objects).
3500 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3501 some references changed. Allocate a copyable data stucture if
3502 none exists. Store info into the copyable data structure.
3503 (bfd_som_set_subsection_attributes): Likewise.
3504 (som_is_space, som_is_subspace, som_is_container): New functions.
3505 Use these instead of directly accessing private data.
3506 (som_prep_headers): Allocate space and subspace headers here.
3507 Fill in some fields in the space/subspace headers from the
3509 (som_bfd_copy_private_section_data): Only copy the stuff
3510 that we really need to make objcopy and strip work. Allocate
3511 the copy_data structure for the output bfd before copying.
3513 * som.h (struct som_exec_data): New structure to hold exec
3514 info that must be preserved when running objcopy/strip.
3515 (struct somdata): Add new "exec_data" field and accessor
3516 macro. Add some comments on how the various fields are used.
3517 (som_section_data_struct): Make is_space and is_subspace bitfields.
3518 Delete unused subspace_index. All references now use the
3519 target_index field within the section structure itself.
3521 * som.c (make_unique_section): Delete unused declaration.
3522 (som_bfd_copy_private_bfd_data): New function.
3523 (som_object_setup): Allocate space for and save exec information
3524 that needs to be copied during objcopy/strip.
3525 (som_mkobject): Do not allocate space for a file header here.
3526 It is not used when only reading SOM objects.
3527 (som_prep_headers): Allocate space for and attach a file header
3528 to the output bfd. For executables, use the saved system_id
3529 value rather than trying to guess the right value. Do not abort
3530 wwhen setting file_hdr->entry* for executables.
3531 (som_begin_writing): For executables, set the exec_entry and
3533 (som_copy_private_backend_section_data): Always return a value.
3535 * libhppa.h (PA_PAGESIZE): Define.
3537 * som.c (SOM_ALIGN): Define.
3538 (som_begin_writing): If writing an executable, initialize all
3539 fields in the exec header to zero. Update fields in the exec
3540 header as sizes of loadable subspaces are computed. Carefully
3541 preserve alignments when building executables. Actually write the
3542 exec after all the fields are filled in.
3544 * Better long-filename handling. Reads SOM ABI compliant extended
3545 names, but doesn't quite write compliant extended names yet.
3546 * som.c (som_slurp_extended_name_table): Delete function. The
3547 generic code will handle things correctly.
3548 (som_slurp_armap): Seek to the beginning of the next member.
3549 (normalize): New function.
3550 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3551 name table into account when computing the file offsets in the
3552 SOM dictionary. Make sure to align to an even boundary.
3553 (som_write_armap): Initialize the checksum to zero.
3554 (ar_maxchars): Fix. Opps.
3556 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3558 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3559 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3561 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3563 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3564 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3565 * bfd-in2.h: Regenerated.
3567 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3568 this was also named trad_unix_bfd_copy_private_bfd_data.
3570 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3572 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3573 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3574 returns NULL, it is not an error. It's possible that some of
3575 these checks are not necessary (because the size can never be
3576 zero), but putting in the checks is the conservative thing to do
3577 in light of the fact that some of these malloc calls replaced
3578 unchecked alloca calls, in which a zero argument would work fine.
3580 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3582 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3583 duplicate definition.
3584 (osf_core_bfd_is_local_label): Define.
3586 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3587 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3588 failure indication, it merely means there are no relocs.
3590 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3591 after NAME, since SunOS /bin/cc can't handle it.
3593 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3595 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3596 From sukes@glue.umd.edu (Tasuki Hirata).
3598 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3600 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3601 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3602 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3604 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3606 * som.c (som_prep_for_fixups): Detect section symbols based
3607 on either the lack of private data or the symbol flags. Do not
3608 munge section symbol names anymore -- they no longer confuse GDB.
3609 (som_begin_writing): Leave space for an exec header if writing
3611 (som_slurp_symbol_table): Recognize both forms of section symbol
3612 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3613 section symbols to be the name of the section they represent.
3614 Debugging symbols begin with "L$0\001", not just "L$".
3616 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3618 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3620 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3621 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3622 and bfd_is_local_label.
3624 * targets.c: Add new entries to the bfd_target structure.
3626 * bfd.c (bfd_copy_private_bfd_data): New definition.
3628 * section.c (bfd_copy_private_section_data): New definition.
3630 * syms.c (bfd_is_local_label): New definition.
3632 * libbfd-in.h (bfd_generic_is_local_label): Declare.
3634 * libbfd.c (bfd_generic_is_local_label): New function.
3636 * *-core.c: Provide default definitions for new functions in
3637 the target vector which all point to bfd_false.
3639 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3640 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3641 Default new vectors for copying private backend data to bfd_true.
3642 Default new vector for determining if a symbol is a local label
3643 to bfd_generic_is_local_label.
3645 * som.c (som_bfd_copy_private_section_data): New function.
3646 (som_bfd_is_local_label): New function.
3647 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3649 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3651 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3653 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3655 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3658 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3659 Indent some of them to GNU standards.
3661 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3662 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3663 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3664 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3665 Update copyright years.
3667 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3669 * som.c (som_prep_for_fixups): A relocation involving the section
3670 symbol for the *ABS* section is really a relocation involving
3672 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3673 undefined symbols. Correctly distinguish between debugger symbols
3674 and section symbols.
3676 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3677 for spaces and subspaces.
3679 * som.c (som_bfd_count_ar_symbols): Fix typo.
3681 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3682 HAS_RELOC based on the object's magic number.
3683 (make_unique_section): Delete function. BFD and its users are
3684 prepared to handle multiple sections with the same name.
3685 (setup_sections): Allocate space on the BFD's obstack to hold
3686 section names. Use bfd_make_setion_anyway rather than the
3687 obsolete make_unique_section.
3688 (som_prep_headers): Choose the correct SOM magic number based
3690 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3692 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3694 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3695 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3696 * Makefile.in, configure.in: Corresponding changes.

3704 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3705 is always located at the start of the data section to allow
3706 recovery of the dynamic info from a stripped executable.
3707 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3710 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3712 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3713 cruft (like the #pragma alloca for AIX).
3714 In addition to that problem, the C alloca calls xmalloc, which
3715 means checking for being out of memory can't work right. The
3716 following changes remove all uses of alloca from BFD.
3717 * hosts/solaris2.h: Remove alloca cruft.
3718 * som.c: Replace alloca with a fixed size auto array.
3719 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3720 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3721 sunos.c: Replace alloca with malloc and appropriate error checking and
3723 * linker.c: Replace alloca with obstack_alloc.
3724 * libbfd.h: Rebuilt.
3726 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
3728 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
3731 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3733 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3734 Elf*_Off typedefs by their expansion, the typedefs have been
3735 removed from include/elf/internal.h.
3736 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3737 SHT_PROGBITS section.
3739 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3741 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3747 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3748 return from bfd_seek indicates an error.
3749 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3750 TRAD_CORE_STACK_OFFSET.
3751 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3752 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3754 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3756 * som.[ch]: Do not include libhppa.h in som.c, instead include
3759 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3760 include it in elf32-hppa.h.
3762 * som.c (log2): Return -1 on error rather than aborting.
3763 (setup_sections): Bubble up an error from log2.
3765 * Changes to make HP C compiler happy in both traditional
3767 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3769 (bfd_som_set_section_attributes): Use unsigned int rather than
3770 unsigned char to avoid GNU-C extensions.
3771 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3772 or failure rather than aborting on failure.
3774 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3776 (bfd_som_attach_aux_hdr): Add prototype.
3777 (hppa_som-gen_reloc_type): Likewise.
3779 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3780 (hppa_look_for_stubs_in_section): Do not return false on failure
3781 until rest of code is ready to handle it. Abort for now.

3806 action in case where caller specified no argument relocation.
3807 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
3808 right in the original relocation and the stub's relocation.
3810 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
3811 unused symbols argument.
3813 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3814 than asymbol * for original target symbol. All callers changed.
3815 Set reloc->sym_ptr_ptr appropriately.
3816 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3817 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3818 argument. Use the output symbols when canonicalizing the relocs,
3819 creating them if necessary.
3821 * linker.c (_bfd_generic_link_output_symbols): Do not
3822 rebuild/clobber the output symbols if they already exist.
3824 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3826 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3827 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3828 * bfd-in2.h: Rebuilt.
3830 * srec.c (hex_value): Always set to a size of 256 bytes.
3831 (srec_init): Cosmetic changes.
3833 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3835 * elf32-hppa.c: Second half of major cleanup. More comments,
3836 PARAMize and staticize rest of functions. Delete unused
3837 functions. Delete unused/unnecessary arguments to some functions.
3838 Group static vars together. Abort for bad errors until we have
3839 error code propogation working. Work on spacing and indention.
3840 Add FIXMEs for unresolved problems. Use enums rather than
3841 #defines for lots of things. Merge two functions which build
3842 linker stubs into a single function (so they can easily share a
3843 ton of common code).
3845 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3847 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3848 avoid depending upon right shifts of signed numbers, and to
3849 correct handling of src_mask with lower bits zero.
3851 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3852 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3877 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3879 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3880 (elf_hppa_tc_make_sections): Likewise.
3881 (elf_hppa_final_processing): Add extern decl.
3883 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3884 comments. PARAMize some static functions. Delete unused functions.
3885 Delete unused/unnecessary arguments to many functions. Group
3886 static vars together. Collapse common case statements together
3887 in many places. Use default case when possible instead of listing
3888 each case separately. Abort for bad errors until we get error
3889 code propogation working. Work on spacing and indention problems.
3890 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3891 COMPLEX relocation support (it's never used anyway).
3892 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3893 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3894 (elf_hppa_tc_make_sections): Likewise.
3896 * format.c (bfd_check_format_matches): Initialize matching_vector
3897 to keep gcc -Wall quiet.

3907 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3909 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4741 use get_value to get the symbol value and check for undefined
4743 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4744 undefined, look it up in the linker hash table.
4746 * aoutx.h (translate_symbol_table): The string index 0 has a

4771 The sparc (and possibly other?) NLM format requires a different
4772 way to write exports, so add a write_export field to the backend
4773 data (and set it to NULL for everything but the sparc).
