2173 required by expansions. Set s and unset h when converting a reloc
2174 from undefined to section. Change handling of PC relative relocs:
2175 if against a section, they are correct in the object file, if
2176 against an external symbol they are pcrel_offset.
2177 (mips_relax_section): New function.
2178 (mips_relax_pcrel16): New function.

2306 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2308 Support for link_order types which generate relocs in order to
2309 support -Ur in the linker.
2310 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2311 from call to _bfd_generic_link_add_one_symbol.
2312 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2313 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2314 instead of bitsize to add_to_set call back.
2315 (_bfd_generic_final_link): Account for link_order relocs when
2316 allocating space for relocations. Handle them in link_order loop.
2317 (_bfd_generic_reloc_link_order): New function.

2335 allocating space for relocations. Handle them in link_order loop.
2336 (ecoff_link_write_external): Set the storage class of a defined
2337 linker created symbol based on the section it is in. Correct
2338 bfd_link_hash_weak case to use .sc rather than .st.

2356 comparison for function symbols within executables.
2358 * som.c (bfd_section_from_som_symbol): Renamed from
2359 som_section_from_subspace_index. Pass in a native SOM symbol.
2360 For executables, iterate through the sections to find out
2361 which contains the symbol's address rather than using the
2362 symbol_info field. (symbol_info has a different meaning for
2363 dynamicly linked executables.)
2365 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2368 * som.c (som_begin_writing): Fix braino (one call to align
2369 space/subspace data was done unconditionally rather than
2370 just for executables.)
2372 * som.c (som_begin_writing): Align text in all executables to
2373 make HPUX kernel happy. Fixes strip/objcopy for shared
2376 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2378 * som.c (som_begin_writing): Account for alignment needs of
2379 subspaces too when writing executables. Never request a negative
2380 bss size. Fixes some problems with demand paged executables,
2381 still having problems with pure executables and shared executables.
2383 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2385 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2386 bfd_zalloc for rawptr, because later on we may call free, not
2389 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2390 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2391 * cisco-core.c: New file.

2398 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2400 * som.h (som_copyable_section_data_struct): New structure
2401 containing all the private section information which needs
2402 to be copied from input section to output section during
2404 (som_section_data_struct): Remove several fields now in
2405 som_copyable_section_data_struct. Make the space and
2406 subspace dictionaries be pointers (to save space when
2407 only reading objects).
2409 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2410 some references changed. Allocate a copyable data stucture if
2411 none exists. Store info into the copyable data structure.
2412 (bfd_som_set_subsection_attributes): Likewise.
2413 (som_is_space, som_is_subspace, som_is_container): New functions.
2414 Use these instead of directly accessing private data.
2415 (som_prep_headers): Allocate space and subspace headers here.
2416 Fill in some fields in the space/subspace headers from the
2418 (som_bfd_copy_private_section_data): Only copy the stuff
2419 that we really need to make objcopy and strip work. Allocate
2420 the copy_data structure for the output bfd before copying.
2422 * som.h (struct som_exec_data): New structure to hold exec
2423 info that must be preserved when running objcopy/strip.
2424 (struct somdata): Add new "exec_data" field and accessor
2425 macro. Add some comments on how the various fields are used.
2426 (som_section_data_struct): Make is_space and is_subspace bitfields.
2427 Delete unused subspace_index. All references now use the
2428 target_index field within the section structure itself.
2430 * som.c (make_unique_section): Delete unused declaration.
2431 (som_bfd_copy_private_bfd_data): New function.
2432 (som_object_setup): Allocate space for and save exec information
2433 that needs to be copied during objcopy/strip.
2434 (som_mkobject): Do not allocate space for a file header here.
2435 It is not used when only reading SOM objects.
2436 (som_prep_headers): Allocate space for and attach a file header
2437 to the output bfd. For executables, use the saved system_id
2438 value rather than trying to guess the right value. Do not abort
2439 wwhen setting file_hdr->entry* for executables.
2440 (som_begin_writing): For executables, set the exec_entry and
2442 (som_copy_private_backend_section_data): Always return a value.
2444 * libhppa.h (PA_PAGESIZE): Define.
2446 * som.c (SOM_ALIGN): Define.
2447 (som_begin_writing): If writing an executable, initialize all
2448 fields in the exec header to zero. Update fields in the exec
2449 header as sizes of loadable subspaces are computed. Carefully
2450 preserve alignments when building executables. Actually write the
2451 exec after all the fields are filled in.
2453 * Better long-filename handling. Reads SOM ABI compliant extended
2454 names, but doesn't quite write compliant extended names yet.
2455 * som.c (som_slurp_extended_name_table): Delete function. The
2456 generic code will handle things correctly.
2457 (som_slurp_armap): Seek to the beginning of the next member.
2458 (normalize): New function.
2459 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2460 name table into account when computing the file offsets in the
2461 SOM dictionary. Make sure to align to an even boundary.
2462 (som_write_armap): Initialize the checksum to zero.
2463 (ar_maxchars): Fix. Opps.

2467 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2468 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

2472 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2473 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2474 * bfd-in2.h: Regenerated.
2476 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2477 this was also named trad_unix_bfd_copy_private_bfd_data.
2479 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2481 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2482 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2483 returns NULL, it is not an error. It's possible that some of
2484 these checks are not necessary (because the size can never be
2485 zero), but putting in the checks is the conservative thing to do
2486 in light of the fact that some of these malloc calls replaced
2487 unchecked alloca calls, in which a zero argument would work fine.
2489 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2491 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2492 duplicate definition.
2493 (osf_core_bfd_is_local_label): Define.
2495 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2496 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2497 failure indication, it merely means there are no relocs.
2499 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2500 after NAME, since SunOS /bin/cc can't handle it.
2502 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2504 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2505 From sukes@glue.umd.edu (Tasuki Hirata).
2507 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2509 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2510 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2511 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2513 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2515 * som.c (som_prep_for_fixups): Detect section symbols based
2516 on either the lack of private data or the symbol flags. Do not
2517 munge section symbol names anymore -- they no longer confuse GDB.
2518 (som_begin_writing): Leave space for an exec header if writing
2520 (som_slurp_symbol_table): Recognize both forms of section symbol
2521 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2522 section symbols to be the name of the section they represent.
2523 Debugging symbols begin with "L$0\001", not just "L$".
2525 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2527 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2529 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2530 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2531 and bfd_is_local_label.

2549 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2550 Default new vectors for copying private backend data to bfd_true.
2551 Default new vector for determining if a symbol is a local label
2552 to bfd_generic_is_local_label.
2554 * som.c (som_bfd_copy_private_section_data): New function.
2555 (som_bfd_is_local_label): New function.
2556 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2558 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2560 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2562 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2564 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2567 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2568 Indent some of them to GNU standards.
2570 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2571 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2573 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2574 Update copyright years.
2576 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2578 * som.c (som_prep_for_fixups): A relocation involving the section
2579 symbol for the *ABS* section is really a relocation involving
2581 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2582 undefined symbols. Correctly distinguish between debugger symbols
2583 and section symbols.
2585 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2586 for spaces and subspaces.
2588 * som.c (som_bfd_count_ar_symbols): Fix typo.
2590 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2591 HAS_RELOC based on the object's magic number.
2592 (make_unique_section): Delete function. BFD and its users are
2593 prepared to handle multiple sections with the same name.
2594 (setup_sections): Allocate space on the BFD's obstack to hold
2595 section names. Use bfd_make_setion_anyway rather than the
2596 obsolete make_unique_section.
2597 (som_prep_headers): Choose the correct SOM magic number based
2599 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

2622 cruft (like the #pragma alloca for AIX).
2623 In addition to that problem, the C alloca calls xmalloc, which
2624 means checking for being out of memory can't work right. The
2625 following changes remove all uses of alloca from BFD.

2922 reasonably. Allocate x_symp using alloca.
2924 * elfcode.h (map_program_segments): ELF program header entries

2976 bother processing them.
2977 (b_out_get_relocated_section_contents): Set reloc_done. Assert
2978 that bfd_get_section_contents returns true. Check that relocs are
2980 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
2981 that reloc->addend falls between the current source offset and the
2982 raw size of the input section.
2984 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
2985 bout. Default with no version number is still bout. Support
2986 explicit i960-coff target too.

3059 Tue Feb 8 08:57:31 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3061 Make all callers of malloc or realloc (including via obstacks)
3062 check the result for NULL. Most set bfd_error to no_memory and

3510 (only testing for m68k and vax at the moment); do verify that the
3511 preprocessor didn't trash the arch name inside the string version.

3653 undefined, look it up in the linker hash table.
3655 * aoutx.h (translate_symbol_table): The string index 0 has a

3680 The sparc (and possibly other?) NLM format requires a different
3681 way to write exports, so add a write_export field to the backend
3682 data (and set it to NULL for everything but the sparc).

3848 sym_filepos as well.
3849 (ecoff_get_extr): Use ifdmap instead of ifdbase.

3921 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

3924 * configure.in (nlm32_alpha_vec): Set target64 to true.
3926 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
3927 different, so there is no point to providing a generic one.
3928 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
3929 in the backend accessor macros; that should no longer be possible.
3930 * targets.c (target_vector): Removed nlm32_big_generic_vec,
3931 nlm64_big_generic_vec, nlm64_little_generic_vec.

4818 * elfcode.h (elf_object_p): Rather than looking through an array
4819 of architectures, get the ELF EM_xxx code from the backend
4820 information. Let the generic ELF target match any EM_xxx code not
4821 matched by another ELF target. Call elf_backend_object_p to let
4822 the backend do more checks and set global information.
4823 * libelf.h (struct elf_backend_data): Added elf_machine_code and
4824 elf_backend_object_p fields.
4825 (struct bfd_elf_arch_map): Removed.

4846 * elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
4847 for R_MIPS_26. Correct overflow detection requires matching the
4848 upper four bits of the destination against the PC. From Ted Lemon
4849 <mellon@pepper.ncd.com>.
4851 * bout.c (b_out_reloc_type_lookup): Return type should point to
4853 * coff-i960.c (coff_i960_reloc_type_lookup): Likewise.

4861 field. Removed unused write_relocs field.
4862 * elf32-target.h: Adjusted elf_backend_data initialization
4864 * elf64-target.h: Corrected elf_backend_data initialization to
4865 fill in all fields and to set elf_64_p to 1.
4867 Mon Nov 8 18:13:14 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

4919 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
4920 in last change. Always rebuild symbol extension section the first
4921 time though if output sections exist (fixes ld -r problems).
4923 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)
4925 * Makefile.in: Add .PHONY for check and installcheck rules.
