2239 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2241 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2242 reloc, used in embedded PIC code.
2243 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2262 _bfd_generic_link_add_symbols but also collect constructors and
2263 destructors by name as collect2 does.
2264 (generic_link_add_symbols): New function, like old
2265 _bfd_generic_link_add_symbols but with collect argument.

2282 extended name table.
2284 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2286 Support for link_order types which generate relocs in order to
2287 support -Ur in the linker.
2288 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2289 from call to _bfd_generic_link_add_one_symbol.
2290 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2291 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2292 instead of bitsize to add_to_set call back.
2293 (_bfd_generic_final_link): Account for link_order relocs when
2294 allocating space for relocations. Handle them in link_order loop.
2295 (_bfd_generic_reloc_link_order): New function.

2313 allocating space for relocations. Handle them in link_order loop.
2314 (ecoff_link_write_external): Set the storage class of a defined
2315 linker created symbol based on the section it is in. Correct
2316 bfd_link_hash_weak case to use .sc rather than .st.
2317 (ecoff_reloc_link_order): New function.
2318 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2320 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2329 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2331 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2333 * som.c (bfd_section_from_som_symbol): Only to do the value
2334 comparison for function symbols within executables.
2336 * som.c (bfd_section_from_som_symbol): Renamed from
2337 som_section_from_subspace_index. Pass in a native SOM symbol.
2338 For executables, iterate through the sections to find out
2339 which contains the symbol's address rather than using the
2340 symbol_info field. (symbol_info has a different meaning for
2341 dynamicly linked executables.)
2343 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2346 * som.c (som_begin_writing): Fix braino (one call to align
2347 space/subspace data was done unconditionally rather than
2348 just for executables.)
2350 * som.c (som_begin_writing): Align text in all executables to
2351 make HPUX kernel happy. Fixes strip/objcopy for shared
2354 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2356 * som.c (som_begin_writing): Account for alignment needs of
2357 subspaces too when writing executables. Never request a negative
2358 bss size. Fixes some problems with demand paged executables,
2359 still having problems with pure executables and shared executables.
2361 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2363 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2364 bfd_zalloc for rawptr, because later on we may call free, not
2367 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2368 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2369 * cisco-core.c: New file.
2370 * Makefile.in: Change accordingly.
2371 * configure.in: Recognize cisco_core_vec.
2372 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2373 * targets.c: Add cisco_core_vec.
2374 * bfd-in2.h: Rebuilt.
2376 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2378 * som.h (som_copyable_section_data_struct): New structure
2379 containing all the private section information which needs
2380 to be copied from input section to output section during
2382 (som_section_data_struct): Remove several fields now in
2383 som_copyable_section_data_struct. Make the space and
2384 subspace dictionaries be pointers (to save space when
2385 only reading objects).
2387 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2388 some references changed. Allocate a copyable data stucture if
2389 none exists. Store info into the copyable data structure.
2390 (bfd_som_set_subsection_attributes): Likewise.
2391 (som_is_space, som_is_subspace, som_is_container): New functions.
2392 Use these instead of directly accessing private data.
2393 (som_prep_headers): Allocate space and subspace headers here.
2394 Fill in some fields in the space/subspace headers from the
2396 (som_bfd_copy_private_section_data): Only copy the stuff
2397 that we really need to make objcopy and strip work. Allocate
2398 the copy_data structure for the output bfd before copying.
2400 * som.h (struct som_exec_data): New structure to hold exec
2401 info that must be preserved when running objcopy/strip.
2402 (struct somdata): Add new "exec_data" field and accessor
2403 macro. Add some comments on how the various fields are used.
2404 (som_section_data_struct): Make is_space and is_subspace bitfields.
2405 Delete unused subspace_index. All references now use the
2406 target_index field within the section structure itself.
2408 * som.c (make_unique_section): Delete unused declaration.
2409 (som_bfd_copy_private_bfd_data): New function.
2410 (som_object_setup): Allocate space for and save exec information
2411 that needs to be copied during objcopy/strip.
2412 (som_mkobject): Do not allocate space for a file header here.
2413 It is not used when only reading SOM objects.
2414 (som_prep_headers): Allocate space for and attach a file header
2415 to the output bfd. For executables, use the saved system_id
2416 value rather than trying to guess the right value. Do not abort
2417 wwhen setting file_hdr->entry* for executables.
2418 (som_begin_writing): For executables, set the exec_entry and
2420 (som_copy_private_backend_section_data): Always return a value.
2422 * libhppa.h (PA_PAGESIZE): Define.
2424 * som.c (SOM_ALIGN): Define.
2425 (som_begin_writing): If writing an executable, initialize all
2426 fields in the exec header to zero. Update fields in the exec
2427 header as sizes of loadable subspaces are computed. Carefully
2428 preserve alignments when building executables. Actually write the
2429 exec after all the fields are filled in.
2431 * Better long-filename handling. Reads SOM ABI compliant extended
2432 names, but doesn't quite write compliant extended names yet.
2433 * som.c (som_slurp_extended_name_table): Delete function. The
2434 generic code will handle things correctly.
2435 (som_slurp_armap): Seek to the beginning of the next member.
2436 (normalize): New function.
2437 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2438 name table into account when computing the file offsets in the
2439 SOM dictionary. Make sure to align to an even boundary.
2440 (som_write_armap): Initialize the checksum to zero.
2441 (ar_maxchars): Fix. Opps.
2443 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2445 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2446 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2448 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2450 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2451 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2452 * bfd-in2.h: Regenerated.
2454 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2455 this was also named trad_unix_bfd_copy_private_bfd_data.
2457 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2459 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2460 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2461 returns NULL, it is not an error. It's possible that some of
2462 these checks are not necessary (because the size can never be
2463 zero), but putting in the checks is the conservative thing to do
2464 in light of the fact that some of these malloc calls replaced
2465 unchecked alloca calls, in which a zero argument would work fine.
2467 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2469 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2470 duplicate definition.
2471 (osf_core_bfd_is_local_label): Define.
2473 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2474 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2475 failure indication, it merely means there are no relocs.
2477 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2478 after NAME, since SunOS /bin/cc can't handle it.
2480 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2482 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2483 From sukes@glue.umd.edu (Tasuki Hirata).
2485 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2487 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2488 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2489 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2491 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2493 * som.c (som_prep_for_fixups): Detect section symbols based
2494 on either the lack of private data or the symbol flags. Do not
2495 munge section symbol names anymore -- they no longer confuse GDB.
2496 (som_begin_writing): Leave space for an exec header if writing
2498 (som_slurp_symbol_table): Recognize both forms of section symbol
2499 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2500 section symbols to be the name of the section they represent.
2501 Debugging symbols begin with "L$0\001", not just "L$".
2503 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2505 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2507 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2508 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2509 and bfd_is_local_label.
2511 * targets.c: Add new entries to the bfd_target structure.
2513 * bfd.c (bfd_copy_private_bfd_data): New definition.
2515 * section.c (bfd_copy_private_section_data): New definition.
2517 * syms.c (bfd_is_local_label): New definition.
2519 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2521 * libbfd.c (bfd_generic_is_local_label): New function.
2523 * *-core.c: Provide default definitions for new functions in
2524 the target vector which all point to bfd_false.
2526 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2527 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2528 Default new vectors for copying private backend data to bfd_true.
2529 Default new vector for determining if a symbol is a local label
2530 to bfd_generic_is_local_label.
2532 * som.c (som_bfd_copy_private_section_data): New function.
2533 (som_bfd_is_local_label): New function.
2534 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2536 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2538 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2540 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2542 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2545 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2546 Indent some of them to GNU standards.
2548 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2549 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2550 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2551 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2552 Update copyright years.
2554 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2556 * som.c (som_prep_for_fixups): A relocation involving the section
2557 symbol for the *ABS* section is really a relocation involving
2559 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2560 undefined symbols. Correctly distinguish between debugger symbols
2561 and section symbols.
2563 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2564 for spaces and subspaces.
2566 * som.c (som_bfd_count_ar_symbols): Fix typo.
2568 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2569 HAS_RELOC based on the object's magic number.
2570 (make_unique_section): Delete function. BFD and its users are
2571 prepared to handle multiple sections with the same name.
2572 (setup_sections): Allocate space on the BFD's obstack to hold
2573 section names. Use bfd_make_setion_anyway rather than the
2574 obsolete make_unique_section.
2575 (som_prep_headers): Choose the correct SOM magic number based
2577 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2579 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2581 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2582 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2583 * Makefile.in, configure.in: Corresponding changes.

2587 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2589 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2591 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2592 is always located at the start of the data section to allow
2593 recovery of the dynamic info from a stripped executable.
2594 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2597 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2599 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2600 cruft (like the #pragma alloca for AIX).
2601 In addition to that problem, the C alloca calls xmalloc, which
2602 means checking for being out of memory can't work right. The
2603 following changes remove all uses of alloca from BFD.
2604 * hosts/solaris2.h: Remove alloca cruft.

2954 bother processing them.
2955 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3658 The sparc (and possibly other?) NLM format requires a different
3659 way to write exports, so add a write_export field to the backend
3660 data (and set it to NULL for everything but the sparc).

3826 sym_filepos as well.
3827 (ecoff_get_extr): Use ifdmap instead of ifdbase.

3899 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

3904 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
3905 different, so there is no point to providing a generic one.
3906 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
3907 in the backend accessor macros; that should no longer be possible.
