3286 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
3287 from call to _bfd_generic_link_add_one_symbol.
3288 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
3289 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR

3336 For executables, iterate through the sections to find out
3337 which contains the symbol's address rather than using the
3338 symbol_info field. (symbol_info has a different meaning for
3339 dynamicly linked executables.)
3341 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
3344 * som.c (som_begin_writing): Fix braino (one call to align
3345 space/subspace data was done unconditionally rather than
3346 just for executables.)
3348 * som.c (som_begin_writing): Align text in all executables to
3349 make HPUX kernel happy. Fixes strip/objcopy for shared
3352 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3354 * som.c (som_begin_writing): Account for alignment needs of
3355 subspaces too when writing executables. Never request a negative
3356 bss size. Fixes some problems with demand paged executables,

3359 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3361 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

3376 * som.h (som_copyable_section_data_struct): New structure
3377 containing all the private section information which needs
3378 to be copied from input section to output section during
3380 (som_section_data_struct): Remove several fields now in
3381 som_copyable_section_data_struct. Make the space and
3382 subspace dictionaries be pointers (to save space when
3383 only reading objects).
3385 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
3386 some references changed. Allocate a copyable data stucture if
3387 none exists. Store info into the copyable data structure.
3388 (bfd_som_set_subsection_attributes): Likewise.
3389 (som_is_space, som_is_subspace, som_is_container): New functions.
3390 Use these instead of directly accessing private data.
3391 (som_prep_headers): Allocate space and subspace headers here.
3392 Fill in some fields in the space/subspace headers from the
3394 (som_bfd_copy_private_section_data): Only copy the stuff
3395 that we really need to make objcopy and strip work. Allocate
3396 the copy_data structure for the output bfd before copying.
3398 * som.h (struct som_exec_data): New structure to hold exec
3399 info that must be preserved when running objcopy/strip.
3400 (struct somdata): Add new "exec_data" field and accessor
3401 macro. Add some comments on how the various fields are used.
3402 (som_section_data_struct): Make is_space and is_subspace bitfields.
3403 Delete unused subspace_index. All references now use the
3404 target_index field within the section structure itself.
3406 * som.c (make_unique_section): Delete unused declaration.
3407 (som_bfd_copy_private_bfd_data): New function.
3408 (som_object_setup): Allocate space for and save exec information
3409 that needs to be copied during objcopy/strip.
3410 (som_mkobject): Do not allocate space for a file header here.
3411 It is not used when only reading SOM objects.
3412 (som_prep_headers): Allocate space for and attach a file header
3413 to the output bfd. For executables, use the saved system_id
3414 value rather than trying to guess the right value. Do not abort
3415 wwhen setting file_hdr->entry* for executables.
3416 (som_begin_writing): For executables, set the exec_entry and
3418 (som_copy_private_backend_section_data): Always return a value.
3420 * libhppa.h (PA_PAGESIZE): Define.
3422 * som.c (SOM_ALIGN): Define.
3423 (som_begin_writing): If writing an executable, initialize all
3424 fields in the exec header to zero. Update fields in the exec
3425 header as sizes of loadable subspaces are computed. Carefully
3426 preserve alignments when building executables. Actually write the
3427 exec after all the fields are filled in.
3429 * Better long-filename handling. Reads SOM ABI compliant extended
3430 names, but doesn't quite write compliant extended names yet.
3431 * som.c (som_slurp_extended_name_table): Delete function. The
3432 generic code will handle things correctly.
3433 (som_slurp_armap): Seek to the beginning of the next member.
3434 (normalize): New function.
3435 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3436 name table into account when computing the file offsets in the
3437 SOM dictionary. Make sure to align to an even boundary.
3438 (som_write_armap): Initialize the checksum to zero.
3439 (ar_maxchars): Fix. Opps.
3441 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3443 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
3444 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
3446 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3448 * bfd-in.h (BFD_VERSION): Use @VERSION@.
3449 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3450 * bfd-in2.h: Regenerated.
3452 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3453 this was also named trad_unix_bfd_copy_private_bfd_data.
3455 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3457 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3458 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3459 returns NULL, it is not an error. It's possible that some of
3460 these checks are not necessary (because the size can never be
3461 zero), but putting in the checks is the conservative thing to do
3462 in light of the fact that some of these malloc calls replaced
3463 unchecked alloca calls, in which a zero argument would work fine.

3472 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3473 failure indication, it merely means there are no relocs.
3475 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3476 after NAME, since SunOS /bin/cc can't handle it.
3478 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3480 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

3485 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3486 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3487 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3489 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3491 * som.c (som_prep_for_fixups): Detect section symbols based
3492 on either the lack of private data or the symbol flags. Do not
3493 munge section symbol names anymore -- they no longer confuse GDB.

3496 (som_slurp_symbol_table): Recognize both forms of section symbol
3497 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3498 section symbols to be the name of the section they represent.
3499 Debugging symbols begin with "L$0\001", not just "L$".

3554 * som.c (som_prep_for_fixups): A relocation involving the section
3555 symbol for the *ABS* section is really a relocation involving
3557 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3558 undefined symbols. Correctly distinguish between debugger symbols
3559 and section symbols.
3561 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3562 for spaces and subspaces.
3564 * som.c (som_bfd_count_ar_symbols): Fix typo.

3569 prepared to handle multiple sections with the same name.
3570 (setup_sections): Allocate space on the BFD's obstack to hold
3571 section names. Use bfd_make_setion_anyway rather than the

3598 cruft (like the #pragma alloca for AIX).
3599 In addition to that problem, the C alloca calls xmalloc, which
3600 means checking for being out of memory can't work right. The
3601 following changes remove all uses of alloca from BFD.
3602 * hosts/solaris2.h: Remove alloca cruft.
3603 * som.c: Replace alloca with a fixed size auto array.

3644 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3645 include it in elf32-hppa.h.
3647 * som.c (log2): Return -1 on error rather than aborting.
3648 (setup_sections): Bubble up an error from log2.
3650 * Changes to make HP C compiler happy in both traditional
3652 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3776 COMPLEX relocation support (it's never used anyway).
3777 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3936 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3938 * section.c (bfd_get_section_contents): Since this function reads
3939 unrelocated contents, the section's raw size is always the one to
3940 use for bounds checking.

3943 link_order size field against cooked size, not raw size, of input
3946 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
3948 (aligncode): When shrinking, the addend should be set to the
3949 current offset in the section plus the number of bytes of padding
3950 that will actually be retained.
3951 (b_out_relax_section): If a section contains no relocations, don't
3952 bother processing them.
3953 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3956 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
3957 that reloc->addend falls between the current source offset and the
3958 raw size of the input section.
3960 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
3961 bout. Default with no version number is still bout. Support

4440 _bfd_generic_link_write_global_symbol): Don't require that all
4441 references to a common symbol be themselves common symbols.

4485 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
4486 (only testing for m68k and vax at the moment); do verify that the
4487 preprocessor didn't trash the arch name inside the string version.

4518 bfd_som_set_subsection_attributes): Change parameters from char
4519 to int. Following a prototype with an old-style function definition

4626 use get_value to get the symbol value and check for undefined
4628 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4629 undefined, look it up in the linker hash table.
4631 * aoutx.h (translate_symbol_table): The string index 0 has a

4656 The sparc (and possibly other?) NLM format requires a different
4657 way to write exports, so add a write_export field to the backend
4658 data (and set it to NULL for everything but the sparc).
