3447 Fill in some fields in the space/subspace headers from the
3449 (som_bfd_copy_private_section_data): Only copy the stuff
3450 that we really need to make objcopy and strip work. Allocate

3454 info that must be preserved when running objcopy/strip.

3464 that needs to be copied during objcopy/strip.
3465 (som_mkobject): Do not allocate space for a file header here.
3466 It is not used when only reading SOM objects.
3467 (som_prep_headers): Allocate space for and attach a file header
3468 to the output bfd. For executables, use the saved system_id
3469 value rather than trying to guess the right value. Do not abort
3470 wwhen setting file_hdr->entry* for executables.
3471 (som_begin_writing): For executables, set the exec_entry and
3473 (som_copy_private_backend_section_data): Always return a value.
3475 * libhppa.h (PA_PAGESIZE): Define.
3477 * som.c (SOM_ALIGN): Define.
3478 (som_begin_writing): If writing an executable, initialize all
3479 fields in the exec header to zero. Update fields in the exec
3480 header as sizes of loadable subspaces are computed. Carefully
3481 preserve alignments when building executables. Actually write the
3482 exec after all the fields are filled in.
3484 * Better long-filename handling. Reads SOM ABI compliant extended
3485 names, but doesn't quite write compliant extended names yet.
3486 * som.c (som_slurp_extended_name_table): Delete function. The
3487 generic code will handle things correctly.
3488 (som_slurp_armap): Seek to the beginning of the next member.
3489 (normalize): New function.
3490 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3491 name table into account when computing the file offsets in the
3492 SOM dictionary. Make sure to align to an even boundary.
3493 (som_write_armap): Initialize the checksum to zero.
3494 (ar_maxchars): Fix. Opps.
3496 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3498 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3499 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3501 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3503 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3504 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3505 * bfd-in2.h: Regenerated.
3507 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3508 this was also named trad_unix_bfd_copy_private_bfd_data.
3510 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3512 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3513 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3514 returns NULL, it is not an error. It's possible that some of
3515 these checks are not necessary (because the size can never be
3516 zero), but putting in the checks is the conservative thing to do
3517 in light of the fact that some of these malloc calls replaced
3518 unchecked alloca calls, in which a zero argument would work fine.
3520 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3522 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3523 duplicate definition.
3524 (osf_core_bfd_is_local_label): Define.
3526 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3527 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3528 failure indication, it merely means there are no relocs.
3530 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3531 after NAME, since SunOS /bin/cc can't handle it.
3533 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3535 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3536 From sukes@glue.umd.edu (Tasuki Hirata).
3538 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3540 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3541 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3542 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3544 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3546 * som.c (som_prep_for_fixups): Detect section symbols based
3547 on either the lack of private data or the symbol flags. Do not
3548 munge section symbol names anymore -- they no longer confuse GDB.
3549 (som_begin_writing): Leave space for an exec header if writing
3551 (som_slurp_symbol_table): Recognize both forms of section symbol
3552 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3553 section symbols to be the name of the section they represent.
3554 Debugging symbols begin with "L$0\001", not just "L$".
3556 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3558 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.

3561 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3562 and bfd_is_local_label.
3564 * targets.c: Add new entries to the bfd_target structure.

3577 the target vector which all point to bfd_false.
3579 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3580 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3581 Default new vectors for copying private backend data to bfd_true.
3582 Default new vector for determining if a symbol is a local label
3583 to bfd_generic_is_local_label.
3585 * som.c (som_bfd_copy_private_section_data): New function.
3586 (som_bfd_is_local_label): New function.
3587 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3589 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3591 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3593 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3595 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3598 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3599 Indent some of them to GNU standards.
3601 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3602 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3603 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3604 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3605 Update copyright years.
3607 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3609 * som.c (som_prep_for_fixups): A relocation involving the section
3610 symbol for the *ABS* section is really a relocation involving
3612 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3613 undefined symbols. Correctly distinguish between debugger symbols
3614 and section symbols.
3616 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3617 for spaces and subspaces.
3619 * som.c (som_bfd_count_ar_symbols): Fix typo.
3621 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3622 HAS_RELOC based on the object's magic number.
3623 (make_unique_section): Delete function. BFD and its users are
3624 prepared to handle multiple sections with the same name.
3625 (setup_sections): Allocate space on the BFD's obstack to hold
3626 section names. Use bfd_make_setion_anyway rather than the
3627 obsolete make_unique_section.
3628 (som_prep_headers): Choose the correct SOM magic number based
3630 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3650 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3652 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3653 cruft (like the #pragma alloca for AIX).
3654 In addition to that problem, the C alloca calls xmalloc, which
3655 means checking for being out of memory can't work right. The
3656 following changes remove all uses of alloca from BFD.
3657 * hosts/solaris2.h: Remove alloca cruft.
3658 * som.c: Replace alloca with a fixed size auto array.

3671 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3673 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3674 Elf*_Off typedefs by their expansion, the typedefs have been
3675 removed from include/elf/internal.h.
3676 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3677 SHT_PROGBITS section.
3679 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3681 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

3690 TRAD_CORE_STACK_OFFSET.
3691 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3692 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3694 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3696 * som.[ch]: Do not include libhppa.h in som.c, instead include
3699 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3700 include it in elf32-hppa.h.
3702 * som.c (log2): Return -1 on error rather than aborting.
3703 (setup_sections): Bubble up an error from log2.
3705 * Changes to make HP C compiler happy in both traditional
3707 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3709 (bfd_som_set_section_attributes): Use unsigned int rather than
3710 unsigned char to avoid GNU-C extensions.
3711 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3712 or failure rather than aborting on failure.
3714 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3716 (bfd_som_attach_aux_hdr): Add prototype.
3717 (hppa_som-gen_reloc_type): Likewise.

3751 unused symbols argument.
3753 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

3755 Set reloc->sym_ptr_ptr appropriately.
3756 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3757 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3758 argument. Use the output symbols when canonicalizing the relocs,
3759 creating them if necessary.
3761 * linker.c (_bfd_generic_link_output_symbols): Do not
3762 rebuild/clobber the output symbols if they already exist.
3764 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)

3776 PARAMize and staticize rest of functions. Delete unused
3777 functions. Delete unused/unnecessary arguments to some functions.

3779 error code propogation working. Work on spacing and indention.
3780 Add FIXMEs for unresolved problems. Use enums rather than
3781 #defines for lots of things. Merge two functions which build
3782 linker stubs into a single function (so they can easily share a
3783 ton of common code).
3785 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3787 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3788 avoid depending upon right shifts of signed numbers, and to
3789 correct handling of src_mask with lower bits zero.

3821 (elf_hppa_final_processing): Add extern decl.
3823 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3824 comments. PARAMize some static functions. Delete unused functions.

3827 in many places. Use default case when possible instead of listing
3828 each case separately. Abort for bad errors until we get error
3829 code propogation working. Work on spacing and indention problems.
3830 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3831 COMPLEX relocation support (it's never used anyway).
3832 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3833 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3834 (elf_hppa_tc_make_sections): Likewise.

3875 * elfcode.h (alloca): Delete declaration.
3877 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
3878 number rather than HP9000S800_ID. Note som.c is careful
3879 to make sure CPU_PA_RISC1_0 is always defined.
3881 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
3883 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

3900 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
3901 operation to avoid OSF 1.3 cc bug.
3902 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
3903 and bss_size bfd_size_type instead of unsigned long. Make
3904 text_start and data_start bfd_vma instead of unsigned long.
3905 * ecofflink.c (ecoff_add_string): Remove incorrect cast of return
3908 Sun Feb 20 16:06:54 1994 Ian Lance Taylor (ian@lisa.cygnus.com)

4573 bfd_som_set_subsection_attributes): Change parameters from char
4574 to int. Following a prototype with an old-style function definition

4681 use get_value to get the symbol value and check for undefined
4683 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4684 undefined, look it up in the linker hash table.
4686 * aoutx.h (translate_symbol_table): The string index 0 has a

4711 The sparc (and possibly other?) NLM format requires a different
4712 way to write exports, so add a write_export field to the backend
4713 data (and set it to NULL for everything but the sparc).

4763 read_dynamic_relocs fields.
4764 * aout-target.h (MY(backend_data)): Initialize
