2154 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2155 argument from declaration.
2156 (_bfd_generic_reloc_link_order): Declare.
2157 (_bfd_count_link_order_relocs): Declare.
2158 * libbfd.h: Rebuilt.
2159 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2160 call to _bfd_generic_link_add_one_symbol.
2161 (NAME(aout,final_link)): Account for link_order relocs when
2162 allocating space for relocations. Handle them after handling all
2164 (aout_link_reloc_link_order): New function.
2165 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2166 call to _bfd_generic_link_add_one_symbol.
2167 (ecoff_bfd_final_link): Account for link_order relocs when
2168 allocating space for relocations. Handle them in link_order loop.
2169 (ecoff_link_write_external): Set the storage class of a defined
2170 linker created symbol based on the section it is in. Correct
2171 bfd_link_hash_weak case to use .sc rather than .st.
2172 (ecoff_reloc_link_order): New function.
2173 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2175 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2177 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2180 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2181 bfd_zmalloc. Free a pointer, not a union.
2182 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2184 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2186 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2188 * som.c (bfd_section_from_som_symbol): Only to do the value
2189 comparison for function symbols within executables.
2191 * som.c (bfd_section_from_som_symbol): Renamed from
2192 som_section_from_subspace_index. Pass in a native SOM symbol.
2193 For executables, iterate through the sections to find out
2194 which contains the symbol's address rather than using the
2195 symbol_info field. (symbol_info has a different meaning for
2196 dynamicly linked executables.)
2198 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2201 * som.c (som_begin_writing): Fix braino (one call to align
2202 space/subspace data was done unconditionally rather than
2203 just for executables.)
2205 * som.c (som_begin_writing): Align text in all executables to
2206 make HPUX kernel happy. Fixes strip/objcopy for shared
2209 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2211 * som.c (som_begin_writing): Account for alignment needs of
2212 subspaces too when writing executables. Never request a negative
2213 bss size. Fixes some problems with demand paged executables,
2214 still having problems with pure executables and shared executables.
2216 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2218 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2219 bfd_zalloc for rawptr, because later on we may call free, not
2222 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2223 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2224 * cisco-core.c: New file.
2225 * Makefile.in: Change accordingly.
2226 * configure.in: Recognize cisco_core_vec.
2227 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2228 * targets.c: Add cisco_core_vec.
2229 * bfd-in2.h: Rebuilt.
2231 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2233 * som.h (som_copyable_section_data_struct): New structure
2234 containing all the private section information which needs
2235 to be copied from input section to output section during
2237 (som_section_data_struct): Remove several fields now in
2238 som_copyable_section_data_struct. Make the space and
2239 subspace dictionaries be pointers (to save space when
2240 only reading objects).
2242 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2243 some references changed. Allocate a copyable data stucture if
2244 none exists. Store info into the copyable data structure.
2245 (bfd_som_set_subsection_attributes): Likewise.
2246 (som_is_space, som_is_subspace, som_is_container): New functions.
2247 Use these instead of directly accessing private data.
2248 (som_prep_headers): Allocate space and subspace headers here.
2249 Fill in some fields in the space/subspace headers from the
2251 (som_bfd_copy_private_section_data): Only copy the stuff
2252 that we really need to make objcopy and strip work. Allocate
2253 the copy_data structure for the output bfd before copying.
2255 * som.h (struct som_exec_data): New structure to hold exec
2256 info that must be preserved when running objcopy/strip.
2257 (struct somdata): Add new "exec_data" field and accessor
2258 macro. Add some comments on how the various fields are used.
2259 (som_section_data_struct): Make is_space and is_subspace bitfields.
2260 Delete unused subspace_index. All references now use the
2261 target_index field within the section structure itself.
2263 * som.c (make_unique_section): Delete unused declaration.
2264 (som_bfd_copy_private_bfd_data): New function.
2265 (som_object_setup): Allocate space for and save exec information
2266 that needs to be copied during objcopy/strip.
2267 (som_mkobject): Do not allocate space for a file header here.
2268 It is not used when only reading SOM objects.
2269 (som_prep_headers): Allocate space for and attach a file header
2270 to the output bfd. For executables, use the saved system_id
2271 value rather than trying to guess the right value. Do not abort
2272 wwhen setting file_hdr->entry* for executables.
2273 (som_begin_writing): For executables, set the exec_entry and
2275 (som_copy_private_backend_section_data): Always return a value.
2277 * libhppa.h (PA_PAGESIZE): Define.
2279 * som.c (SOM_ALIGN): Define.
2280 (som_begin_writing): If writing an executable, initialize all
2281 fields in the exec header to zero. Update fields in the exec
2282 header as sizes of loadable subspaces are computed. Carefully
2283 preserve alignments when building executables. Actually write the
2284 exec after all the fields are filled in.
2286 * Better long-filename handling. Reads SOM ABI compliant extended
2287 names, but doesn't quite write compliant extended names yet.
2288 * som.c (som_slurp_extended_name_table): Delete function. The
2289 generic code will handle things correctly.
2290 (som_slurp_armap): Seek to the beginning of the next member.
2291 (normalize): New function.
2292 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2293 name table into account when computing the file offsets in the
2294 SOM dictionary. Make sure to align to an even boundary.
2295 (som_write_armap): Initialize the checksum to zero.
2296 (ar_maxchars): Fix. Opps.
2298 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2300 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2301 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2303 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2305 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2306 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2307 * bfd-in2.h: Regenerated.
2309 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2310 this was also named trad_unix_bfd_copy_private_bfd_data.
2312 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2314 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2315 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2316 returns NULL, it is not an error. It's possible that some of
2317 these checks are not necessary (because the size can never be
2318 zero), but putting in the checks is the conservative thing to do
2319 in light of the fact that some of these malloc calls replaced
2320 unchecked alloca calls, in which a zero argument would work fine.
2322 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2324 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2325 duplicate definition.
2326 (osf_core_bfd_is_local_label): Define.
2328 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2329 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2330 failure indication, it merely means there are no relocs.
2332 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2333 after NAME, since SunOS /bin/cc can't handle it.
2335 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2337 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2338 From sukes@glue.umd.edu (Tasuki Hirata).
2340 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2342 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2343 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2344 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2346 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2348 * som.c (som_prep_for_fixups): Detect section symbols based
2349 on either the lack of private data or the symbol flags. Do not
2350 munge section symbol names anymore -- they no longer confuse GDB.
2351 (som_begin_writing): Leave space for an exec header if writing
2353 (som_slurp_symbol_table): Recognize both forms of section symbol
2354 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2355 section symbols to be the name of the section they represent.
2356 Debugging symbols begin with "L$0\001", not just "L$".
2358 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2360 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2362 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2363 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2364 and bfd_is_local_label.
2366 * targets.c: Add new entries to the bfd_target structure.
2368 * bfd.c (bfd_copy_private_bfd_data): New definition.
2370 * section.c (bfd_copy_private_section_data): New definition.
2372 * syms.c (bfd_is_local_label): New definition.
2374 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2376 * libbfd.c (bfd_generic_is_local_label): New function.
2378 * *-core.c: Provide default definitions for new functions in
2379 the target vector which all point to bfd_false.
2381 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2382 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2383 Default new vectors for copying private backend data to bfd_true.
2384 Default new vector for determining if a symbol is a local label
2385 to bfd_generic_is_local_label.
2387 * som.c (som_bfd_copy_private_section_data): New function.
2388 (som_bfd_is_local_label): New function.
2389 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2391 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2393 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2395 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2397 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2400 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2401 Indent some of them to GNU standards.
2403 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2404 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2405 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2406 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2407 Update copyright years.
2409 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2411 * som.c (som_prep_for_fixups): A relocation involving the section
2412 symbol for the *ABS* section is really a relocation involving
2414 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2415 undefined symbols. Correctly distinguish between debugger symbols
2416 and section symbols.
2418 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2419 for spaces and subspaces.
2421 * som.c (som_bfd_count_ar_symbols): Fix typo.
2423 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2424 HAS_RELOC based on the object's magic number.
2425 (make_unique_section): Delete function. BFD and its users are
2426 prepared to handle multiple sections with the same name.
2427 (setup_sections): Allocate space on the BFD's obstack to hold
2428 section names. Use bfd_make_setion_anyway rather than the
2429 obsolete make_unique_section.
2430 (som_prep_headers): Choose the correct SOM magic number based
2432 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2434 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2436 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2437 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2438 * Makefile.in, configure.in: Corresponding changes.
2440 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2442 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2444 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2446 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2447 is always located at the start of the data section to allow
2448 recovery of the dynamic info from a stripped executable.
2449 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2452 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2454 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2455 cruft (like the #pragma alloca for AIX).
2456 In addition to that problem, the C alloca calls xmalloc, which
2457 means checking for being out of memory can't work right. The
2458 following changes remove all uses of alloca from BFD.
2459 * hosts/solaris2.h: Remove alloca cruft.
2460 * som.c: Replace alloca with a fixed size auto array.
2461 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2462 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2463 sunos.c: Replace alloca with malloc and appropriate error checking and
2465 * linker.c: Replace alloca with obstack_alloc.
2466 * libbfd.h: Rebuilt.
2468 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2470 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2473 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2475 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2476 Elf*_Off typedefs by their expansion, the typedefs have been
2477 removed from include/elf/internal.h.
2478 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2479 SHT_PROGBITS section.
2481 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2483 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2487 * configure.host: Recognize i[34]86-sequent-*.
2489 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2490 return from bfd_seek indicates an error.
2491 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2492 TRAD_CORE_STACK_OFFSET.
2493 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2494 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2496 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2498 * som.[ch]: Do not include libhppa.h in som.c, instead include
2501 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2502 include it in elf32-hppa.h.
2504 * som.c (log2): Return -1 on error rather than aborting.
2505 (setup_sections): Bubble up an error from log2.
2507 * Changes to make HP C compiler happy in both traditional
2509 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2511 (bfd_som_set_section_attributes): Use unsigned int rather than
2512 unsigned char to avoid GNU-C extensions.
2513 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2514 or failure rather than aborting on failure.
2516 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2518 (bfd_som_attach_aux_hdr): Add prototype.
2519 (hppa_som-gen_reloc_type): Likewise.
2521 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2522 (hppa_look_for_stubs_in_section): Do not return false on failure
2523 until rest of code is ready to handle it. Abort for now.
2525 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2527 * bfd-in2.h: Rebuilt.
2529 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

2538 * config/i386-os9k.mt : Newly add os9k target makefile.
2540 * i386os9k.c : new file to handle os9k format bfd.
2541 * Makefile.in : Handle new file i386os9k.c
2542 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2543 * cache.c : Initialize cache_sentinel to 0.

2547 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2548 action in case where caller specified no argument relocation.
2549 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2550 right in the original relocation and the stub's relocation.
2552 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2553 unused symbols argument.
2555 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2556 than asymbol * for original target symbol. All callers changed.
2557 Set reloc->sym_ptr_ptr appropriately.
2558 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2559 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2560 argument. Use the output symbols when canonicalizing the relocs,
2561 creating them if necessary.
2563 * linker.c (_bfd_generic_link_output_symbols): Do not
2564 rebuild/clobber the output symbols if they already exist.
2566 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2568 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2569 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2570 * bfd-in2.h: Rebuilt.
2572 * srec.c (hex_value): Always set to a size of 256 bytes.
2573 (srec_init): Cosmetic changes.
2575 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2577 * elf32-hppa.c: Second half of major cleanup. More comments,
2578 PARAMize and staticize rest of functions. Delete unused
2579 functions. Delete unused/unnecessary arguments to some functions.
2580 Group static vars together. Abort for bad errors until we have
2581 error code propogation working. Work on spacing and indention.
2582 Add FIXMEs for unresolved problems. Use enums rather than
2583 #defines for lots of things. Merge two functions which build
2584 linker stubs into a single function (so they can easily share a
2585 ton of common code).
2587 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2589 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2590 avoid depending upon right shifts of signed numbers, and to
2591 correct handling of src_mask with lower bits zero.
2593 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2594 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

2809 bother processing them.
