3355 dynamicly linked executables.)
3357 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3360 * som.c (som_begin_writing): Fix braino (one call to align

3397 som_copyable_section_data_struct. Make the space and
3398 subspace dictionaries be pointers (to save space when
3399 only reading objects).
3401 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3402 some references changed. Allocate a copyable data stucture if
3403 none exists. Store info into the copyable data structure.

3405 (som_is_space, som_is_subspace, som_is_container): New functions.
3406 Use these instead of directly accessing private data.
3407 (som_prep_headers): Allocate space and subspace headers here.
3408 Fill in some fields in the space/subspace headers from the
3410 (som_bfd_copy_private_section_data): Only copy the stuff
3411 that we really need to make objcopy and strip work. Allocate
3412 the copy_data structure for the output bfd before copying.
3414 * som.h (struct som_exec_data): New structure to hold exec
3415 info that must be preserved when running objcopy/strip.
3416 (struct somdata): Add new "exec_data" field and accessor
3417 macro. Add some comments on how the various fields are used.
3418 (som_section_data_struct): Make is_space and is_subspace bitfields.

3427 It is not used when only reading SOM objects.
3428 (som_prep_headers): Allocate space for and attach a file header
3429 to the output bfd. For executables, use the saved system_id
3430 value rather than trying to guess the right value. Do not abort
3431 wwhen setting file_hdr->entry* for executables.
3432 (som_begin_writing): For executables, set the exec_entry and
3434 (som_copy_private_backend_section_data): Always return a value.
3436 * libhppa.h (PA_PAGESIZE): Define.

3439 (som_begin_writing): If writing an executable, initialize all
3440 fields in the exec header to zero. Update fields in the exec
3441 header as sizes of loadable subspaces are computed. Carefully
3442 preserve alignments when building executables. Actually write the
3443 exec after all the fields are filled in.
3445 * Better long-filename handling. Reads SOM ABI compliant extended
3446 names, but doesn't quite write compliant extended names yet.
3447 * som.c (som_slurp_extended_name_table): Delete function. The
3448 generic code will handle things correctly.
3449 (som_slurp_armap): Seek to the beginning of the next member.
3450 (normalize): New function.
3451 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3452 name table into account when computing the file offsets in the
3453 SOM dictionary. Make sure to align to an even boundary.
3454 (som_write_armap): Initialize the checksum to zero.

3468 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3469 this was also named trad_unix_bfd_copy_private_bfd_data.
3471 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3473 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3474 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3475 returns NULL, it is not an error. It's possible that some of
3476 these checks are not necessary (because the size can never be
3477 zero), but putting in the checks is the conservative thing to do
3478 in light of the fact that some of these malloc calls replaced
3479 unchecked alloca calls, in which a zero argument would work fine.
3481 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3483 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3484 duplicate definition.

3487 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3488 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3489 failure indication, it merely means there are no relocs.
3491 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3492 after NAME, since SunOS /bin/cc can't handle it.
3494 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3496 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3497 From sukes@glue.umd.edu (Tasuki Hirata).
3499 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3501 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3502 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3503 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3505 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3507 * som.c (som_prep_for_fixups): Detect section symbols based
3508 on either the lack of private data or the symbol flags. Do not
3509 munge section symbol names anymore -- they no longer confuse GDB.
3510 (som_begin_writing): Leave space for an exec header if writing
3512 (som_slurp_symbol_table): Recognize both forms of section symbol
3513 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3514 section symbols to be the name of the section they represent.
3515 Debugging symbols begin with "L$0\001", not just "L$".
3517 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3541 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3542 Default new vectors for copying private backend data to bfd_true.
3543 Default new vector for determining if a symbol is a local label
3544 to bfd_generic_is_local_label.
3546 * som.c (som_bfd_copy_private_section_data): New function.
3547 (som_bfd_is_local_label): New function.

3552 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3554 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3556 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3559 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3560 Indent some of them to GNU standards.
3562 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3563 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
3564 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
3565 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3566 Update copyright years.
3568 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3570 * som.c (som_prep_for_fixups): A relocation involving the section
3571 symbol for the *ABS* section is really a relocation involving
3573 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3574 undefined symbols. Correctly distinguish between debugger symbols
3575 and section symbols.
3577 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3578 for spaces and subspaces.
3580 * som.c (som_bfd_count_ar_symbols): Fix typo.
3582 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3583 HAS_RELOC based on the object's magic number.
3584 (make_unique_section): Delete function. BFD and its users are
3585 prepared to handle multiple sections with the same name.
3586 (setup_sections): Allocate space on the BFD's obstack to hold
3587 section names. Use bfd_make_setion_anyway rather than the
3588 obsolete make_unique_section.
3589 (som_prep_headers): Choose the correct SOM magic number based
3591 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3611 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3613 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3614 cruft (like the #pragma alloca for AIX).
3615 In addition to that problem, the C alloca calls xmalloc, which
3616 means checking for being out of memory can't work right. The
3617 following changes remove all uses of alloca from BFD.
3618 * hosts/solaris2.h: Remove alloca cruft.
3619 * som.c: Replace alloca with a fixed size auto array.

3632 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3634 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3635 Elf*_Off typedefs by their expansion, the typedefs have been
3636 removed from include/elf/internal.h.
3637 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3638 SHT_PROGBITS section.

3651 TRAD_CORE_STACK_OFFSET.
3652 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3653 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

3657 * som.[ch]: Do not include libhppa.h in som.c, instead include
3660 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3661 include it in elf32-hppa.h.
3663 * som.c (log2): Return -1 on error rather than aborting.
3664 (setup_sections): Bubble up an error from log2.
3666 * Changes to make HP C compiler happy in both traditional
3668 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3670 (bfd_som_set_section_attributes): Use unsigned int rather than
3671 unsigned char to avoid GNU-C extensions.
3672 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3673 or failure rather than aborting on failure.
3675 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3718 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3719 argument. Use the output symbols when canonicalizing the relocs,
3720 creating them if necessary.
3722 * linker.c (_bfd_generic_link_output_symbols): Do not
3723 rebuild/clobber the output symbols if they already exist.

3741 Add FIXMEs for unresolved problems. Use enums rather than
3742 #defines for lots of things. Merge two functions which build
3743 linker stubs into a single function (so they can easily share a
3744 ton of common code).

3748 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

3792 COMPLEX relocation support (it's never used anyway).
3793 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3794 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3795 (elf_hppa_tc_make_sections): Likewise.

3968 bother processing them.
3969 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4383 "unsigned", some compilers don't like it after "unsigned".
4384 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
4385 "val" in prototype declaration because some compilers don't like
4386 arguments whose names are the same as types.

4431 fields. If the string offset is 0, always use an empty string as
4433 (coff_make_empty_symbol): Zero out the symbol structure.

4456 _bfd_generic_link_write_global_symbol): Don't require that all
4457 references to a common symbol be themselves common symbols.

4501 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
4502 (only testing for m68k and vax at the moment); do verify that the
4503 preprocessor didn't trash the arch name inside the string version.

4534 bfd_som_set_subsection_attributes): Change parameters from char
4535 to int. Following a prototype with an old-style function definition

4642 use get_value to get the symbol value and check for undefined
4644 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4645 undefined, look it up in the linker hash table.
4647 * aoutx.h (translate_symbol_table): The string index 0 has a

4672 The sparc (and possibly other?) NLM format requires a different
4673 way to write exports, so add a write_export field to the backend
4674 data (and set it to NULL for everything but the sparc).
