2154 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2155 add_symbls entry point.
2157 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2158 counting relocs. Set SEC_RELOC flag for any section which has

2163 * linker.c (_bfd_generic_link_add_symbols): Just call
2164 generic_link_add_symbols.
2165 (_bfd_generic_link_add_symbols_collect): New function, like
2166 _bfd_generic_link_add_symbols but also collect constructors and
2167 destructors by name as collect2 does.
2168 (generic_link_add_symbols): New function, like old
2169 _bfd_generic_link_add_symbols but with collect argument.
2170 (generic_link_add_object_symbols): Take collect argument.

2182 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2183 for first character in an extended name.
2184 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2185 "//" as the name of the special archive member holding the
2186 extended name table.
2188 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2190 Support for link_order types which generate relocs in order to
2191 support -Ur in the linker.
2192 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2193 from call to _bfd_generic_link_add_one_symbol.
2194 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2195 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2196 instead of bitsize to add_to_set call back.
2197 (_bfd_generic_final_link): Account for link_order relocs when
2198 allocating space for relocations. Handle them in link_order loop.
2199 (_bfd_generic_reloc_link_order): New function.
2200 (_bfd_default_link_order): If a reloc_link_order is seen here,
2202 (_bfd_count_link_order_relocs): New function.
2203 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2204 argument from declaration.
2205 (_bfd_generic_reloc_link_order): Declare.
2206 (_bfd_count_link_order_relocs): Declare.
2207 * libbfd.h: Rebuilt.
2208 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2209 call to _bfd_generic_link_add_one_symbol.
2210 (NAME(aout,final_link)): Account for link_order relocs when

2215 call to _bfd_generic_link_add_one_symbol.
2216 (ecoff_bfd_final_link): Account for link_order relocs when
2217 allocating space for relocations. Handle them in link_order loop.
2218 (ecoff_link_write_external): Set the storage class of a defined
2219 linker created symbol based on the section it is in. Correct
2220 bfd_link_hash_weak case to use .sc rather than .st.
2221 (ecoff_reloc_link_order): New function.
2222 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2224 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2226 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2229 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2230 bfd_zmalloc. Free a pointer, not a union.
2231 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2233 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2235 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2237 * som.c (bfd_section_from_som_symbol): Only to do the value
2238 comparison for function symbols within executables.
2240 * som.c (bfd_section_from_som_symbol): Renamed from
2241 som_section_from_subspace_index. Pass in a native SOM symbol.
2242 For executables, iterate through the sections to find out
2243 which contains the symbol's address rather than using the
2244 symbol_info field. (symbol_info has a different meaning for
2245 dynamicly linked executables.)
2247 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2250 * som.c (som_begin_writing): Fix braino (one call to align
2251 space/subspace data was done unconditionally rather than
2252 just for executables.)
2254 * som.c (som_begin_writing): Align text in all executables to
2255 make HPUX kernel happy. Fixes strip/objcopy for shared
2258 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2260 * som.c (som_begin_writing): Account for alignment needs of
2261 subspaces too when writing executables. Never request a negative
2262 bss size. Fixes some problems with demand paged executables,
2263 still having problems with pure executables and shared executables.
2265 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2267 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2268 bfd_zalloc for rawptr, because later on we may call free, not
2271 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2272 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2273 * cisco-core.c: New file.
2274 * Makefile.in: Change accordingly.
2275 * configure.in: Recognize cisco_core_vec.
2276 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2277 * targets.c: Add cisco_core_vec.
2278 * bfd-in2.h: Rebuilt.
2280 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2282 * som.h (som_copyable_section_data_struct): New structure
2283 containing all the private section information which needs
2284 to be copied from input section to output section during
2286 (som_section_data_struct): Remove several fields now in
2287 som_copyable_section_data_struct. Make the space and
2288 subspace dictionaries be pointers (to save space when
2289 only reading objects).
2291 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2292 some references changed. Allocate a copyable data stucture if
2293 none exists. Store info into the copyable data structure.
2294 (bfd_som_set_subsection_attributes): Likewise.
2295 (som_is_space, som_is_subspace, som_is_container): New functions.
2296 Use these instead of directly accessing private data.
2297 (som_prep_headers): Allocate space and subspace headers here.
2298 Fill in some fields in the space/subspace headers from the
2300 (som_bfd_copy_private_section_data): Only copy the stuff
2301 that we really need to make objcopy and strip work. Allocate
2302 the copy_data structure for the output bfd before copying.
2304 * som.h (struct som_exec_data): New structure to hold exec
2305 info that must be preserved when running objcopy/strip.
2306 (struct somdata): Add new "exec_data" field and accessor
2307 macro. Add some comments on how the various fields are used.
2308 (som_section_data_struct): Make is_space and is_subspace bitfields.
2309 Delete unused subspace_index. All references now use the
2310 target_index field within the section structure itself.
2312 * som.c (make_unique_section): Delete unused declaration.
2313 (som_bfd_copy_private_bfd_data): New function.
2314 (som_object_setup): Allocate space for and save exec information
2315 that needs to be copied during objcopy/strip.
2316 (som_mkobject): Do not allocate space for a file header here.
2317 It is not used when only reading SOM objects.
2318 (som_prep_headers): Allocate space for and attach a file header
2319 to the output bfd. For executables, use the saved system_id
2320 value rather than trying to guess the right value. Do not abort
2321 wwhen setting file_hdr->entry* for executables.
2322 (som_begin_writing): For executables, set the exec_entry and
2324 (som_copy_private_backend_section_data): Always return a value.
2326 * libhppa.h (PA_PAGESIZE): Define.
2328 * som.c (SOM_ALIGN): Define.
2329 (som_begin_writing): If writing an executable, initialize all
2330 fields in the exec header to zero. Update fields in the exec
2331 header as sizes of loadable subspaces are computed. Carefully
2332 preserve alignments when building executables. Actually write the
2333 exec after all the fields are filled in.
2335 * Better long-filename handling. Reads SOM ABI compliant extended
2336 names, but doesn't quite write compliant extended names yet.
2337 * som.c (som_slurp_extended_name_table): Delete function. The
2338 generic code will handle things correctly.
2339 (som_slurp_armap): Seek to the beginning of the next member.
2340 (normalize): New function.
2341 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2342 name table into account when computing the file offsets in the
2343 SOM dictionary. Make sure to align to an even boundary.
2344 (som_write_armap): Initialize the checksum to zero.
2345 (ar_maxchars): Fix. Opps.
2347 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2349 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2350 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2352 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2354 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2355 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2356 * bfd-in2.h: Regenerated.
2358 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2359 this was also named trad_unix_bfd_copy_private_bfd_data.
2361 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2363 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2364 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2365 returns NULL, it is not an error. It's possible that some of
2366 these checks are not necessary (because the size can never be
2367 zero), but putting in the checks is the conservative thing to do
2368 in light of the fact that some of these malloc calls replaced
2369 unchecked alloca calls, in which a zero argument would work fine.
2371 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2373 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2374 duplicate definition.
2375 (osf_core_bfd_is_local_label): Define.
2377 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2378 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2379 failure indication, it merely means there are no relocs.
2381 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2382 after NAME, since SunOS /bin/cc can't handle it.
2384 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2386 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2387 From sukes@glue.umd.edu (Tasuki Hirata).
2389 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2391 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2392 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2393 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2395 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2397 * som.c (som_prep_for_fixups): Detect section symbols based
2398 on either the lack of private data or the symbol flags. Do not
2399 munge section symbol names anymore -- they no longer confuse GDB.
2400 (som_begin_writing): Leave space for an exec header if writing
2402 (som_slurp_symbol_table): Recognize both forms of section symbol
2403 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2404 section symbols to be the name of the section they represent.
2405 Debugging symbols begin with "L$0\001", not just "L$".
2407 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2409 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2411 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2412 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2413 and bfd_is_local_label.
2415 * targets.c: Add new entries to the bfd_target structure.
2417 * bfd.c (bfd_copy_private_bfd_data): New definition.
2419 * section.c (bfd_copy_private_section_data): New definition.
2421 * syms.c (bfd_is_local_label): New definition.
2423 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2425 * libbfd.c (bfd_generic_is_local_label): New function.
2427 * *-core.c: Provide default definitions for new functions in
2428 the target vector which all point to bfd_false.
2430 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2431 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2432 Default new vectors for copying private backend data to bfd_true.
2433 Default new vector for determining if a symbol is a local label
2434 to bfd_generic_is_local_label.
2436 * som.c (som_bfd_copy_private_section_data): New function.
2437 (som_bfd_is_local_label): New function.
2438 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2440 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2442 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2444 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2446 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2449 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2450 Indent some of them to GNU standards.
2452 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2453 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2454 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2455 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2456 Update copyright years.
2458 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2460 * som.c (som_prep_for_fixups): A relocation involving the section
2461 symbol for the *ABS* section is really a relocation involving
2463 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2464 undefined symbols. Correctly distinguish between debugger symbols
2465 and section symbols.
2467 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2468 for spaces and subspaces.
2470 * som.c (som_bfd_count_ar_symbols): Fix typo.
2472 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2473 HAS_RELOC based on the object's magic number.
2474 (make_unique_section): Delete function. BFD and its users are
2475 prepared to handle multiple sections with the same name.
2476 (setup_sections): Allocate space on the BFD's obstack to hold
2477 section names. Use bfd_make_setion_anyway rather than the
2478 obsolete make_unique_section.
2479 (som_prep_headers): Choose the correct SOM magic number based
2481 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

2495 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2496 is always located at the start of the data section to allow
2497 recovery of the dynamic info from a stripped executable.
2498 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2501 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2503 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2504 cruft (like the #pragma alloca for AIX).
2505 In addition to that problem, the C alloca calls xmalloc, which
2506 means checking for being out of memory can't work right. The
2507 following changes remove all uses of alloca from BFD.
2508 * hosts/solaris2.h: Remove alloca cruft.
2509 * som.c: Replace alloca with a fixed size auto array.

2514 * linker.c: Replace alloca with obstack_alloc.
2515 * libbfd.h: Rebuilt.
2517 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2519 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2522 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2524 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2525 Elf*_Off typedefs by their expansion, the typedefs have been
2526 removed from include/elf/internal.h.
2527 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2528 SHT_PROGBITS section.
2530 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2532 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2536 * configure.host: Recognize i[34]86-sequent-*.
2538 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2539 return from bfd_seek indicates an error.
2540 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2541 TRAD_CORE_STACK_OFFSET.
2542 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2543 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2545 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2547 * som.[ch]: Do not include libhppa.h in som.c, instead include
2550 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2551 include it in elf32-hppa.h.
2553 * som.c (log2): Return -1 on error rather than aborting.
2554 (setup_sections): Bubble up an error from log2.
2556 * Changes to make HP C compiler happy in both traditional
2558 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2560 (bfd_som_set_section_attributes): Use unsigned int rather than
2561 unsigned char to avoid GNU-C extensions.
2562 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2563 or failure rather than aborting on failure.
2565 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2567 (bfd_som_attach_aux_hdr): Add prototype.
2568 (hppa_som-gen_reloc_type): Likewise.
2570 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2571 (hppa_look_for_stubs_in_section): Do not return false on failure
2572 until rest of code is ready to handle it. Abort for now.
2574 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2576 * bfd-in2.h: Rebuilt.
2578 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

2682 COMPLEX relocation support (it's never used anyway).
2683 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2684 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).

2857 (b_out_relax_section): If a section contains no relocations, don't
2858 bother processing them.
2859 (b_out_get_relocated_section_contents): Set reloc_done. Assert
2860 that bfd_get_section_contents returns true. Check that relocs are

3562 The sparc (and possibly other?) NLM format requires a different
3563 way to write exports, so add a write_export field to the backend
3564 data (and set it to NULL for everything but the sparc).

4800 * From Pete Hoogenboom (hoogen@cs.utah.edu)
4801 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
4802 in last change. Always rebuild symbol extension section the first
4803 time though if output sections exist (fixes ld -r problems).
4805 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)

4816 * libbfd.h (artdata): Use long, not time_t for portability, at
4819 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
4821 * config.bfd: Use bigmips for mips*-*-bsd*.
4823 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4825 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
4826 Handle symbol number of zero.
4828 * reloc.c (enum bfd_reloc_code_real): Added
4829 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
4830 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
4831 * bfd-in2.h: Rebuilt.
4832 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
4833 BFD_RELOC_MIPS_LITERAL.
4834 * elf32-mips.c (mips_reloc_map): Handle new relocs.
4835 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
4838 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
4839 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
4840 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
4841 MY_bfd_seclet_link): Define.
4842 (MY_bfd_reloc_type_lookup): Rename from
4843 MY_reloc_howto_type_lookup.
4844 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
4845 (MY(vec)): Use JUMP_TABLE rather than listing functions.
4846 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
4847 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
4848 terms of MY, because that causes a recusive invocation of CAT when
4849 expanded within JUMP_TABLE, and ANSI compilers don't expand
4851 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
4852 MY_reloc_howto_type_lookup, and don't define in terms of MY.
4853 (MY_canonicalize_reloc): Don't define in terms of MY.
4854 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
4855 than listing functions.
