2216 required by expansions. Set s and unset h when converting a reloc
2217 from undefined to section. Change handling of PC relative relocs:
2218 if against a section, they are correct in the object file, if
2219 against an external symbol they are pcrel_offset.
2220 (mips_relax_section): New function.
2221 (mips_relax_pcrel16): New function.

2307 reloc, used in embedded PIC code.
2308 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
2309 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

2316 add_symbls entry point.
2318 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2319 counting relocs. Set SEC_RELOC flag for any section which has

2347 extended name table.
2349 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2351 Support for link_order types which generate relocs in order to
2352 support -Ur in the linker.
2353 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2354 from call to _bfd_generic_link_add_one_symbol.
2355 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2356 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2357 instead of bitsize to add_to_set call back.
2358 (_bfd_generic_final_link): Account for link_order relocs when
2359 allocating space for relocations. Handle them in link_order loop.
2360 (_bfd_generic_reloc_link_order): New function.

2378 allocating space for relocations. Handle them in link_order loop.
2379 (ecoff_link_write_external): Set the storage class of a defined
2380 linker created symbol based on the section it is in. Correct
2381 bfd_link_hash_weak case to use .sc rather than .st.
2382 (ecoff_reloc_link_order): New function.
2383 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2385 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2391 bfd_zmalloc. Free a pointer, not a union.
2392 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2394 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2396 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2398 * som.c (bfd_section_from_som_symbol): Only to do the value
2399 comparison for function symbols within executables.
2401 * som.c (bfd_section_from_som_symbol): Renamed from
2402 som_section_from_subspace_index. Pass in a native SOM symbol.
2403 For executables, iterate through the sections to find out
2404 which contains the symbol's address rather than using the
2405 symbol_info field. (symbol_info has a different meaning for
2406 dynamicly linked executables.)
2408 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2411 * som.c (som_begin_writing): Fix braino (one call to align
2412 space/subspace data was done unconditionally rather than
2413 just for executables.)
2415 * som.c (som_begin_writing): Align text in all executables to
2416 make HPUX kernel happy. Fixes strip/objcopy for shared
2419 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2421 * som.c (som_begin_writing): Account for alignment needs of
2422 subspaces too when writing executables. Never request a negative
2423 bss size. Fixes some problems with demand paged executables,
2424 still having problems with pure executables and shared executables.
2426 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2428 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2429 bfd_zalloc for rawptr, because later on we may call free, not
2432 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2433 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2434 * cisco-core.c: New file.

2436 * configure.in: Recognize cisco_core_vec.
2437 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

2441 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2443 * som.h (som_copyable_section_data_struct): New structure
2444 containing all the private section information which needs
2445 to be copied from input section to output section during
2447 (som_section_data_struct): Remove several fields now in
2448 som_copyable_section_data_struct. Make the space and
2449 subspace dictionaries be pointers (to save space when
2450 only reading objects).
2452 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2453 some references changed. Allocate a copyable data stucture if
2454 none exists. Store info into the copyable data structure.
2455 (bfd_som_set_subsection_attributes): Likewise.
2456 (som_is_space, som_is_subspace, som_is_container): New functions.
2457 Use these instead of directly accessing private data.
2458 (som_prep_headers): Allocate space and subspace headers here.
2459 Fill in some fields in the space/subspace headers from the
2461 (som_bfd_copy_private_section_data): Only copy the stuff
2462 that we really need to make objcopy and strip work. Allocate
2463 the copy_data structure for the output bfd before copying.
2465 * som.h (struct som_exec_data): New structure to hold exec
2466 info that must be preserved when running objcopy/strip.
2467 (struct somdata): Add new "exec_data" field and accessor
2468 macro. Add some comments on how the various fields are used.
2469 (som_section_data_struct): Make is_space and is_subspace bitfields.
2470 Delete unused subspace_index. All references now use the
2471 target_index field within the section structure itself.
2473 * som.c (make_unique_section): Delete unused declaration.
2474 (som_bfd_copy_private_bfd_data): New function.
2475 (som_object_setup): Allocate space for and save exec information
2476 that needs to be copied during objcopy/strip.
2477 (som_mkobject): Do not allocate space for a file header here.
2478 It is not used when only reading SOM objects.
2479 (som_prep_headers): Allocate space for and attach a file header
2480 to the output bfd. For executables, use the saved system_id
2481 value rather than trying to guess the right value. Do not abort
2482 wwhen setting file_hdr->entry* for executables.
2483 (som_begin_writing): For executables, set the exec_entry and
2485 (som_copy_private_backend_section_data): Always return a value.
2487 * libhppa.h (PA_PAGESIZE): Define.
2489 * som.c (SOM_ALIGN): Define.
2490 (som_begin_writing): If writing an executable, initialize all
2491 fields in the exec header to zero. Update fields in the exec
2492 header as sizes of loadable subspaces are computed. Carefully
2493 preserve alignments when building executables. Actually write the
2494 exec after all the fields are filled in.
2496 * Better long-filename handling. Reads SOM ABI compliant extended
2497 names, but doesn't quite write compliant extended names yet.
2498 * som.c (som_slurp_extended_name_table): Delete function. The
2499 generic code will handle things correctly.
2500 (som_slurp_armap): Seek to the beginning of the next member.
2501 (normalize): New function.
2502 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2503 name table into account when computing the file offsets in the
2504 SOM dictionary. Make sure to align to an even boundary.
2505 (som_write_armap): Initialize the checksum to zero.
2506 (ar_maxchars): Fix. Opps.
2508 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2510 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2511 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2513 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2515 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2516 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2517 * bfd-in2.h: Regenerated.
2519 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2520 this was also named trad_unix_bfd_copy_private_bfd_data.
2522 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2524 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2525 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2526 returns NULL, it is not an error. It's possible that some of
2527 these checks are not necessary (because the size can never be
2528 zero), but putting in the checks is the conservative thing to do
2529 in light of the fact that some of these malloc calls replaced
2530 unchecked alloca calls, in which a zero argument would work fine.
2532 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2534 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2535 duplicate definition.
2536 (osf_core_bfd_is_local_label): Define.
2538 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2539 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2540 failure indication, it merely means there are no relocs.
2542 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2543 after NAME, since SunOS /bin/cc can't handle it.
2545 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2547 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2548 From sukes@glue.umd.edu (Tasuki Hirata).
2550 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2552 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2553 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2554 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2556 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2558 * som.c (som_prep_for_fixups): Detect section symbols based
2559 on either the lack of private data or the symbol flags. Do not
2560 munge section symbol names anymore -- they no longer confuse GDB.
2561 (som_begin_writing): Leave space for an exec header if writing
2563 (som_slurp_symbol_table): Recognize both forms of section symbol
2564 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2565 section symbols to be the name of the section they represent.
2566 Debugging symbols begin with "L$0\001", not just "L$".
2568 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2570 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2572 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2573 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2574 and bfd_is_local_label.
2576 * targets.c: Add new entries to the bfd_target structure.

2589 the target vector which all point to bfd_false.
2591 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2592 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2593 Default new vectors for copying private backend data to bfd_true.
2594 Default new vector for determining if a symbol is a local label
2595 to bfd_generic_is_local_label.
2597 * som.c (som_bfd_copy_private_section_data): New function.
2598 (som_bfd_is_local_label): New function.
2599 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2601 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2603 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2605 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2607 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)

2665 cruft (like the #pragma alloca for AIX).
2666 In addition to that problem, the C alloca calls xmalloc, which
