2170 * aoutx.h (NAME(aout,find_nearest_line)): The caller expects
2171 functionname_ptr to be set to a symbol name, so prepend
2172 symbol_leading_char.

2246 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2248 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2249 reloc, used in embedded PIC code.
2250 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2269 _bfd_generic_link_add_symbols but also collect constructors and
2270 destructors by name as collect2 does.
2271 (generic_link_add_symbols): New function, like old
2272 _bfd_generic_link_add_symbols but with collect argument.

2289 extended name table.
2291 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2293 Support for link_order types which generate relocs in order to
2294 support -Ur in the linker.
2295 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2296 from call to _bfd_generic_link_add_one_symbol.
2297 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2298 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2299 instead of bitsize to add_to_set call back.
2300 (_bfd_generic_final_link): Account for link_order relocs when
2301 allocating space for relocations. Handle them in link_order loop.
2302 (_bfd_generic_reloc_link_order): New function.

2320 allocating space for relocations. Handle them in link_order loop.
2321 (ecoff_link_write_external): Set the storage class of a defined
2322 linker created symbol based on the section it is in. Correct
2323 bfd_link_hash_weak case to use .sc rather than .st.
2324 (ecoff_reloc_link_order): New function.
2325 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2327 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2336 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2338 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2340 * som.c (bfd_section_from_som_symbol): Only to do the value
2341 comparison for function symbols within executables.
2343 * som.c (bfd_section_from_som_symbol): Renamed from
2344 som_section_from_subspace_index. Pass in a native SOM symbol.
2345 For executables, iterate through the sections to find out
2346 which contains the symbol's address rather than using the
2347 symbol_info field. (symbol_info has a different meaning for
2348 dynamicly linked executables.)
2350 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2353 * som.c (som_begin_writing): Fix braino (one call to align
2354 space/subspace data was done unconditionally rather than
2355 just for executables.)
2357 * som.c (som_begin_writing): Align text in all executables to
2358 make HPUX kernel happy. Fixes strip/objcopy for shared
2361 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2363 * som.c (som_begin_writing): Account for alignment needs of
2364 subspaces too when writing executables. Never request a negative
2365 bss size. Fixes some problems with demand paged executables,
2366 still having problems with pure executables and shared executables.
2368 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2370 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2371 bfd_zalloc for rawptr, because later on we may call free, not
2374 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2375 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2376 * cisco-core.c: New file.
2377 * Makefile.in: Change accordingly.
2378 * configure.in: Recognize cisco_core_vec.
2379 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2380 * targets.c: Add cisco_core_vec.
2381 * bfd-in2.h: Rebuilt.
2383 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2385 * som.h (som_copyable_section_data_struct): New structure
2386 containing all the private section information which needs
2387 to be copied from input section to output section during
2389 (som_section_data_struct): Remove several fields now in
2390 som_copyable_section_data_struct. Make the space and
2391 subspace dictionaries be pointers (to save space when
2392 only reading objects).
2394 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2395 some references changed. Allocate a copyable data stucture if
2396 none exists. Store info into the copyable data structure.
2397 (bfd_som_set_subsection_attributes): Likewise.
2398 (som_is_space, som_is_subspace, som_is_container): New functions.
2399 Use these instead of directly accessing private data.
2400 (som_prep_headers): Allocate space and subspace headers here.
2401 Fill in some fields in the space/subspace headers from the
2403 (som_bfd_copy_private_section_data): Only copy the stuff
2404 that we really need to make objcopy and strip work. Allocate
2405 the copy_data structure for the output bfd before copying.
2407 * som.h (struct som_exec_data): New structure to hold exec
2408 info that must be preserved when running objcopy/strip.
2409 (struct somdata): Add new "exec_data" field and accessor
2410 macro. Add some comments on how the various fields are used.
2411 (som_section_data_struct): Make is_space and is_subspace bitfields.
2412 Delete unused subspace_index. All references now use the
2413 target_index field within the section structure itself.
2415 * som.c (make_unique_section): Delete unused declaration.
2416 (som_bfd_copy_private_bfd_data): New function.
2417 (som_object_setup): Allocate space for and save exec information
2418 that needs to be copied during objcopy/strip.
2419 (som_mkobject): Do not allocate space for a file header here.
2420 It is not used when only reading SOM objects.
2421 (som_prep_headers): Allocate space for and attach a file header
2422 to the output bfd. For executables, use the saved system_id
2423 value rather than trying to guess the right value. Do not abort
2424 wwhen setting file_hdr->entry* for executables.
2425 (som_begin_writing): For executables, set the exec_entry and
2427 (som_copy_private_backend_section_data): Always return a value.
2429 * libhppa.h (PA_PAGESIZE): Define.
2431 * som.c (SOM_ALIGN): Define.
2432 (som_begin_writing): If writing an executable, initialize all
2433 fields in the exec header to zero. Update fields in the exec
2434 header as sizes of loadable subspaces are computed. Carefully
2435 preserve alignments when building executables. Actually write the
2436 exec after all the fields are filled in.
2438 * Better long-filename handling. Reads SOM ABI compliant extended
2439 names, but doesn't quite write compliant extended names yet.
2440 * som.c (som_slurp_extended_name_table): Delete function. The
2441 generic code will handle things correctly.
2442 (som_slurp_armap): Seek to the beginning of the next member.
2443 (normalize): New function.
2444 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2445 name table into account when computing the file offsets in the
2446 SOM dictionary. Make sure to align to an even boundary.
2447 (som_write_armap): Initialize the checksum to zero.
2448 (ar_maxchars): Fix. Opps.
2450 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2452 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2453 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2455 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2457 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2458 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2459 * bfd-in2.h: Regenerated.
2461 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2462 this was also named trad_unix_bfd_copy_private_bfd_data.
2464 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2466 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2467 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2468 returns NULL, it is not an error. It's possible that some of
2469 these checks are not necessary (because the size can never be
2470 zero), but putting in the checks is the conservative thing to do
2471 in light of the fact that some of these malloc calls replaced
2472 unchecked alloca calls, in which a zero argument would work fine.
2474 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2476 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2477 duplicate definition.
2478 (osf_core_bfd_is_local_label): Define.
2480 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2481 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2482 failure indication, it merely means there are no relocs.
2484 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2485 after NAME, since SunOS /bin/cc can't handle it.
2487 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2489 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2490 From sukes@glue.umd.edu (Tasuki Hirata).
2492 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2494 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2495 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2496 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2498 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2500 * som.c (som_prep_for_fixups): Detect section symbols based
2501 on either the lack of private data or the symbol flags. Do not
2502 munge section symbol names anymore -- they no longer confuse GDB.
2503 (som_begin_writing): Leave space for an exec header if writing
2505 (som_slurp_symbol_table): Recognize both forms of section symbol
2506 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2507 section symbols to be the name of the section they represent.
2508 Debugging symbols begin with "L$0\001", not just "L$".
2510 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2512 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2514 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2515 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2516 and bfd_is_local_label.
2518 * targets.c: Add new entries to the bfd_target structure.
2520 * bfd.c (bfd_copy_private_bfd_data): New definition.
2522 * section.c (bfd_copy_private_section_data): New definition.
2524 * syms.c (bfd_is_local_label): New definition.
2526 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2528 * libbfd.c (bfd_generic_is_local_label): New function.
2530 * *-core.c: Provide default definitions for new functions in
2531 the target vector which all point to bfd_false.
2533 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2534 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2535 Default new vectors for copying private backend data to bfd_true.
2536 Default new vector for determining if a symbol is a local label
2537 to bfd_generic_is_local_label.
2539 * som.c (som_bfd_copy_private_section_data): New function.
2540 (som_bfd_is_local_label): New function.
2541 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2543 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2545 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2547 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2549 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2552 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2553 Indent some of them to GNU standards.
2555 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2556 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2557 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2558 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2559 Update copyright years.
2561 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2563 * som.c (som_prep_for_fixups): A relocation involving the section
2564 symbol for the *ABS* section is really a relocation involving
2566 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2567 undefined symbols. Correctly distinguish between debugger symbols
2568 and section symbols.
2570 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2571 for spaces and subspaces.
2573 * som.c (som_bfd_count_ar_symbols): Fix typo.
2575 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2576 HAS_RELOC based on the object's magic number.
2577 (make_unique_section): Delete function. BFD and its users are
2578 prepared to handle multiple sections with the same name.
2579 (setup_sections): Allocate space on the BFD's obstack to hold
2580 section names. Use bfd_make_setion_anyway rather than the
2581 obsolete make_unique_section.
2582 (som_prep_headers): Choose the correct SOM magic number based
2584 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2586 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2588 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2589 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2590 * Makefile.in, configure.in: Corresponding changes.
2592 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2594 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2596 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2598 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2599 is always located at the start of the data section to allow
2600 recovery of the dynamic info from a stripped executable.
2601 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2604 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2606 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2607 cruft (like the #pragma alloca for AIX).
2608 In addition to that problem, the C alloca calls xmalloc, which
2609 means checking for being out of memory can't work right. The

2961 bother processing them.
2962 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3046 Make all callers of malloc or realloc (including via obstacks)
3047 check the result for NULL. Most set bfd_error to no_memory and

3468 * coff-mips.c (mips_ecoff_backend_data), coff-alpha.c
3469 (alpha_ecoff_backend_data): Change casts of aux_in and aux_out

3490 new arguments to swap_aux functions.
3492 Sun Jan 30 15:14:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3494 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
3495 (only testing for m68k and vax at the moment); do verify that the

3665 The sparc (and possibly other?) NLM format requires a different
3666 way to write exports, so add a write_export field to the backend
3667 data (and set it to NULL for everything but the sparc).

3833 sym_filepos as well.
3834 (ecoff_get_extr): Use ifdmap instead of ifdbase.

3906 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

3911 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
3912 different, so there is no point to providing a generic one.
3913 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
3914 in the backend accessor macros; that should no longer be possible.
