3374 dynamicly linked executables.)
3376 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3379 * som.c (som_begin_writing): Fix braino (one call to align

3416 som_copyable_section_data_struct. Make the space and
3417 subspace dictionaries be pointers (to save space when
3418 only reading objects).

3421 some references changed. Allocate a copyable data stucture if
3422 none exists. Store info into the copyable data structure.

3424 (som_is_space, som_is_subspace, som_is_container): New functions.
3425 Use these instead of directly accessing private data.

3427 Fill in some fields in the space/subspace headers from the
3429 (som_bfd_copy_private_section_data): Only copy the stuff
3430 that we really need to make objcopy and strip work. Allocate
3431 the copy_data structure for the output bfd before copying.
3433 * som.h (struct som_exec_data): New structure to hold exec
3434 info that must be preserved when running objcopy/strip.
3435 (struct somdata): Add new "exec_data" field and accessor
3436 macro. Add some comments on how the various fields are used.
3437 (som_section_data_struct): Make is_space and is_subspace bitfields.

3446 It is not used when only reading SOM objects.
3447 (som_prep_headers): Allocate space for and attach a file header
3448 to the output bfd. For executables, use the saved system_id
3449 value rather than trying to guess the right value. Do not abort
3450 wwhen setting file_hdr->entry* for executables.
3451 (som_begin_writing): For executables, set the exec_entry and
3453 (som_copy_private_backend_section_data): Always return a value.
3455 * libhppa.h (PA_PAGESIZE): Define.

3458 (som_begin_writing): If writing an executable, initialize all
3459 fields in the exec header to zero. Update fields in the exec
3460 header as sizes of loadable subspaces are computed. Carefully
3461 preserve alignments when building executables. Actually write the
3462 exec after all the fields are filled in.
3464 * Better long-filename handling. Reads SOM ABI compliant extended
3465 names, but doesn't quite write compliant extended names yet.
3466 * som.c (som_slurp_extended_name_table): Delete function. The
3467 generic code will handle things correctly.
3468 (som_slurp_armap): Seek to the beginning of the next member.
3469 (normalize): New function.
3470 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3471 name table into account when computing the file offsets in the
3472 SOM dictionary. Make sure to align to an even boundary.
3473 (som_write_armap): Initialize the checksum to zero.
3474 (ar_maxchars): Fix. Opps.
3476 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3478 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3479 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3481 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3483 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3484 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3485 * bfd-in2.h: Regenerated.
3487 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3488 this was also named trad_unix_bfd_copy_private_bfd_data.
3490 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3492 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3493 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3494 returns NULL, it is not an error. It's possible that some of
3495 these checks are not necessary (because the size can never be
3496 zero), but putting in the checks is the conservative thing to do
3497 in light of the fact that some of these malloc calls replaced
3498 unchecked alloca calls, in which a zero argument would work fine.
3500 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3502 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3503 duplicate definition.

3506 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3507 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3508 failure indication, it merely means there are no relocs.
3510 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3511 after NAME, since SunOS /bin/cc can't handle it.
3513 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3515 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3516 From sukes@glue.umd.edu (Tasuki Hirata).
3518 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3520 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3521 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3522 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3524 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3526 * som.c (som_prep_for_fixups): Detect section symbols based
3527 on either the lack of private data or the symbol flags. Do not
3528 munge section symbol names anymore -- they no longer confuse GDB.
3529 (som_begin_writing): Leave space for an exec header if writing
3531 (som_slurp_symbol_table): Recognize both forms of section symbol
3532 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3533 section symbols to be the name of the section they represent.
3534 Debugging symbols begin with "L$0\001", not just "L$".
3536 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3541 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3542 and bfd_is_local_label.

3560 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3561 Default new vectors for copying private backend data to bfd_true.
3562 Default new vector for determining if a symbol is a local label
3563 to bfd_generic_is_local_label.
3565 * som.c (som_bfd_copy_private_section_data): New function.
3566 (som_bfd_is_local_label): New function.
3567 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3569 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3571 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3573 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3575 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3578 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3579 Indent some of them to GNU standards.
3581 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3582 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3583 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3584 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3585 Update copyright years.
3587 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3589 * som.c (som_prep_for_fixups): A relocation involving the section
3590 symbol for the *ABS* section is really a relocation involving
3592 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3593 undefined symbols. Correctly distinguish between debugger symbols
3594 and section symbols.
3596 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3597 for spaces and subspaces.
3599 * som.c (som_bfd_count_ar_symbols): Fix typo.
3601 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3602 HAS_RELOC based on the object's magic number.
3603 (make_unique_section): Delete function. BFD and its users are
3604 prepared to handle multiple sections with the same name.
3605 (setup_sections): Allocate space on the BFD's obstack to hold
3606 section names. Use bfd_make_setion_anyway rather than the
3607 obsolete make_unique_section.
3608 (som_prep_headers): Choose the correct SOM magic number based
3610 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3630 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3632 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3633 cruft (like the #pragma alloca for AIX).
3634 In addition to that problem, the C alloca calls xmalloc, which
3635 means checking for being out of memory can't work right. The
3636 following changes remove all uses of alloca from BFD.
3637 * hosts/solaris2.h: Remove alloca cruft.
3638 * som.c: Replace alloca with a fixed size auto array.

3651 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3653 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3654 Elf*_Off typedefs by their expansion, the typedefs have been
3655 removed from include/elf/internal.h.
3656 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3657 SHT_PROGBITS section.

3670 TRAD_CORE_STACK_OFFSET.
3671 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3672 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

3676 * som.[ch]: Do not include libhppa.h in som.c, instead include
3679 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3680 include it in elf32-hppa.h.
3682 * som.c (log2): Return -1 on error rather than aborting.
3683 (setup_sections): Bubble up an error from log2.
3685 * Changes to make HP C compiler happy in both traditional
3687 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3690 unsigned char to avoid GNU-C extensions.
3691 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3692 or failure rather than aborting on failure.
3694 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3737 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3738 argument. Use the output symbols when canonicalizing the relocs,
3739 creating them if necessary.
3741 * linker.c (_bfd_generic_link_output_symbols): Do not
3742 rebuild/clobber the output symbols if they already exist.

3760 Add FIXMEs for unresolved problems. Use enums rather than
3761 #defines for lots of things. Merge two functions which build
3762 linker stubs into a single function (so they can easily share a
3763 ton of common code).
3765 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3767 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

3811 COMPLEX relocation support (it's never used anyway).
3812 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3859 to make sure CPU_PA_RISC1_0 is always defined.
3861 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
3863 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

4402 "unsigned", some compilers don't like it after "unsigned".
4403 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

4475 _bfd_generic_link_write_global_symbol): Don't require that all

4521 (only testing for m68k and vax at the moment); do verify that the
4522 preprocessor didn't trash the arch name inside the string version.

4553 bfd_som_set_subsection_attributes): Change parameters from char
4554 to int. Following a prototype with an old-style function definition

4661 use get_value to get the symbol value and check for undefined
4663 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4664 undefined, look it up in the linker hash table.
4666 * aoutx.h (translate_symbol_table): The string index 0 has a

4691 The sparc (and possibly other?) NLM format requires a different
4692 way to write exports, so add a write_export field to the backend
4693 data (and set it to NULL for everything but the sparc).

4743 read_dynamic_relocs fields.
4744 * aout-target.h (MY(backend_data)): Initialize
