3344 which contains the symbol's address rather than using the
3345 symbol_info field. (symbol_info has a different meaning for
3346 dynamicly linked executables.)
3348 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3351 * som.c (som_begin_writing): Fix braino (one call to align

3388 som_copyable_section_data_struct. Make the space and
3389 subspace dictionaries be pointers (to save space when
3390 only reading objects).
3392 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3393 some references changed. Allocate a copyable data stucture if
3394 none exists. Store info into the copyable data structure.

3396 (som_is_space, som_is_subspace, som_is_container): New functions.
3397 Use these instead of directly accessing private data.
3398 (som_prep_headers): Allocate space and subspace headers here.
3399 Fill in some fields in the space/subspace headers from the
3401 (som_bfd_copy_private_section_data): Only copy the stuff
3402 that we really need to make objcopy and strip work. Allocate
3403 the copy_data structure for the output bfd before copying.
3405 * som.h (struct som_exec_data): New structure to hold exec
3406 info that must be preserved when running objcopy/strip.
3407 (struct somdata): Add new "exec_data" field and accessor
3408 macro. Add some comments on how the various fields are used.
3409 (som_section_data_struct): Make is_space and is_subspace bitfields.

3418 It is not used when only reading SOM objects.
3419 (som_prep_headers): Allocate space for and attach a file header
3420 to the output bfd. For executables, use the saved system_id
3421 value rather than trying to guess the right value. Do not abort
3422 wwhen setting file_hdr->entry* for executables.
3423 (som_begin_writing): For executables, set the exec_entry and
3425 (som_copy_private_backend_section_data): Always return a value.
3427 * libhppa.h (PA_PAGESIZE): Define.

3430 (som_begin_writing): If writing an executable, initialize all
3431 fields in the exec header to zero. Update fields in the exec
3432 header as sizes of loadable subspaces are computed. Carefully
3433 preserve alignments when building executables. Actually write the
3434 exec after all the fields are filled in.
3436 * Better long-filename handling. Reads SOM ABI compliant extended
3437 names, but doesn't quite write compliant extended names yet.
3438 * som.c (som_slurp_extended_name_table): Delete function. The
3439 generic code will handle things correctly.
3440 (som_slurp_armap): Seek to the beginning of the next member.
3441 (normalize): New function.
3442 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3443 name table into account when computing the file offsets in the
3444 SOM dictionary. Make sure to align to an even boundary.
3445 (som_write_armap): Initialize the checksum to zero.
3446 (ar_maxchars): Fix. Opps.

3464 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3465 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3466 returns NULL, it is not an error. It's possible that some of
3467 these checks are not necessary (because the size can never be
3468 zero), but putting in the checks is the conservative thing to do
3469 in light of the fact that some of these malloc calls replaced
3470 unchecked alloca calls, in which a zero argument would work fine.
3472 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3474 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3475 duplicate definition.

3478 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3479 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3480 failure indication, it merely means there are no relocs.
3482 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3483 after NAME, since SunOS /bin/cc can't handle it.
3485 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3487 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3488 From sukes@glue.umd.edu (Tasuki Hirata).
3490 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3492 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3493 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3494 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3496 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3498 * som.c (som_prep_for_fixups): Detect section symbols based
3499 on either the lack of private data or the symbol flags. Do not
3500 munge section symbol names anymore -- they no longer confuse GDB.
3501 (som_begin_writing): Leave space for an exec header if writing
3503 (som_slurp_symbol_table): Recognize both forms of section symbol
3504 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3505 section symbols to be the name of the section they represent.
3506 Debugging symbols begin with "L$0\001", not just "L$".

3532 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3533 Default new vectors for copying private backend data to bfd_true.

3535 to bfd_generic_is_local_label.
3537 * som.c (som_bfd_copy_private_section_data): New function.
3538 (som_bfd_is_local_label): New function.

3543 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3545 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3547 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3550 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3551 Indent some of them to GNU standards.
3553 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3554 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3556 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3557 Update copyright years.
3559 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3561 * som.c (som_prep_for_fixups): A relocation involving the section
3562 symbol for the *ABS* section is really a relocation involving
3564 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3565 undefined symbols. Correctly distinguish between debugger symbols
3566 and section symbols.
3568 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3569 for spaces and subspaces.
3571 * som.c (som_bfd_count_ar_symbols): Fix typo.
3573 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3574 HAS_RELOC based on the object's magic number.
3575 (make_unique_section): Delete function. BFD and its users are
3576 prepared to handle multiple sections with the same name.
3577 (setup_sections): Allocate space on the BFD's obstack to hold
3578 section names. Use bfd_make_setion_anyway rather than the
3579 obsolete make_unique_section.

3602 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3604 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3605 cruft (like the #pragma alloca for AIX).
3606 In addition to that problem, the C alloca calls xmalloc, which
3607 means checking for being out of memory can't work right. The
3608 following changes remove all uses of alloca from BFD.
3609 * hosts/solaris2.h: Remove alloca cruft.
3610 * som.c: Replace alloca with a fixed size auto array.

3625 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3626 Elf*_Off typedefs by their expansion, the typedefs have been
3627 removed from include/elf/internal.h.
3628 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3629 SHT_PROGBITS section.

3648 * som.[ch]: Do not include libhppa.h in som.c, instead include
3651 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3652 include it in elf32-hppa.h.
3654 * som.c (log2): Return -1 on error rather than aborting.
3655 (setup_sections): Bubble up an error from log2.
3657 * Changes to make HP C compiler happy in both traditional
3659 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3662 unsigned char to avoid GNU-C extensions.
3663 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3664 or failure rather than aborting on failure.
3666 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3709 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3710 argument. Use the output symbols when canonicalizing the relocs,
3711 creating them if necessary.
3713 * linker.c (_bfd_generic_link_output_symbols): Do not
3714 rebuild/clobber the output symbols if they already exist.

3733 #defines for lots of things. Merge two functions which build
3734 linker stubs into a single function (so they can easily share a
3735 ton of common code).

3783 COMPLEX relocation support (it's never used anyway).
3784 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3785 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3786 (elf_hppa_tc_make_sections): Likewise.

3958 (b_out_relax_section): If a section contains no relocations, don't
3959 bother processing them.
3960 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3964 that reloc->addend falls between the current source offset and the
3965 raw size of the input section.
3967 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
3968 bout. Default with no version number is still bout. Support

3988 * Finish basic read-write support for SOM archive libraries. Bugs
3989 surely remain as this hasn't been tested all that much.
3990 * som.c (SOM_LST_HASH_SIZE, SOM_LST_MODULE_LIMIT): Define.
3991 (struct som_misc_symbol_info): New structure to hold info necessary

4009 * coff-rs6000.c: Add Lynx core file support, use HOST_AIX, where
4011 * rs6000-core.c: Use HOST_AIX instead of COREFILES_PLEASE.

4044 Make all callers of malloc or realloc (including via obstacks)
4045 check the result for NULL. Most set bfd_error to no_memory and

4493 (only testing for m68k and vax at the moment); do verify that the
4494 preprocessor didn't trash the arch name inside the string version.

4525 bfd_som_set_subsection_attributes): Change parameters from char
4526 to int. Following a prototype with an old-style function definition

4633 use get_value to get the symbol value and check for undefined
4635 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4636 undefined, look it up in the linker hash table.
4638 * aoutx.h (translate_symbol_table): The string index 0 has a

4663 The sparc (and possibly other?) NLM format requires a different
4664 way to write exports, so add a write_export field to the backend
4665 data (and set it to NULL for everything but the sparc).
