2155 allocating space for relocations. Handle them in link_order loop.
2156 (_bfd_generic_reloc_link_order): New function.
2157 (_bfd_default_link_order): If a reloc_link_order is seen here,
2159 (_bfd_count_link_order_relocs): New function.
2160 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2161 argument from declaration.
2162 (_bfd_generic_reloc_link_order): Declare.
2163 (_bfd_count_link_order_relocs): Declare.
2164 * libbfd.h: Rebuilt.
2165 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2166 call to _bfd_generic_link_add_one_symbol.
2167 (NAME(aout,final_link)): Account for link_order relocs when
2168 allocating space for relocations. Handle them after handling all
2170 (aout_link_reloc_link_order): New function.
2171 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2172 call to _bfd_generic_link_add_one_symbol.
2173 (ecoff_bfd_final_link): Account for link_order relocs when
2174 allocating space for relocations. Handle them in link_order loop.
2175 (ecoff_link_write_external): Set the storage class of a defined
2176 linker created symbol based on the section it is in. Correct
2177 bfd_link_hash_weak case to use .sc rather than .st.
2178 (ecoff_reloc_link_order): New function.
2179 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2181 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2183 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2186 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2187 bfd_zmalloc. Free a pointer, not a union.
2188 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2190 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2192 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2194 * som.c (bfd_section_from_som_symbol): Only to do the value
2195 comparison for function symbols within executables.
2197 * som.c (bfd_section_from_som_symbol): Renamed from
2198 som_section_from_subspace_index. Pass in a native SOM symbol.
2199 For executables, iterate through the sections to find out
2200 which contains the symbol's address rather than using the
2201 symbol_info field. (symbol_info has a different meaning for
2202 dynamicly linked executables.)
2204 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2207 * som.c (som_begin_writing): Fix braino (one call to align
2208 space/subspace data was done unconditionally rather than
2209 just for executables.)
2211 * som.c (som_begin_writing): Align text in all executables to
2212 make HPUX kernel happy. Fixes strip/objcopy for shared
2215 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2217 * som.c (som_begin_writing): Account for alignment needs of
2218 subspaces too when writing executables. Never request a negative
2219 bss size. Fixes some problems with demand paged executables,
2220 still having problems with pure executables and shared executables.
2222 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2224 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2225 bfd_zalloc for rawptr, because later on we may call free, not
2228 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2229 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2230 * cisco-core.c: New file.
2231 * Makefile.in: Change accordingly.
2232 * configure.in: Recognize cisco_core_vec.
2233 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2234 * targets.c: Add cisco_core_vec.
2235 * bfd-in2.h: Rebuilt.
2237 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2239 * som.h (som_copyable_section_data_struct): New structure
2240 containing all the private section information which needs
2241 to be copied from input section to output section during
2243 (som_section_data_struct): Remove several fields now in
2244 som_copyable_section_data_struct. Make the space and
2245 subspace dictionaries be pointers (to save space when
2246 only reading objects).
2248 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2249 some references changed. Allocate a copyable data stucture if
2250 none exists. Store info into the copyable data structure.
2251 (bfd_som_set_subsection_attributes): Likewise.
2252 (som_is_space, som_is_subspace, som_is_container): New functions.
2253 Use these instead of directly accessing private data.
2254 (som_prep_headers): Allocate space and subspace headers here.
2255 Fill in some fields in the space/subspace headers from the
2257 (som_bfd_copy_private_section_data): Only copy the stuff
2258 that we really need to make objcopy and strip work. Allocate
2259 the copy_data structure for the output bfd before copying.
2261 * som.h (struct som_exec_data): New structure to hold exec
2262 info that must be preserved when running objcopy/strip.
2263 (struct somdata): Add new "exec_data" field and accessor
2264 macro. Add some comments on how the various fields are used.
2265 (som_section_data_struct): Make is_space and is_subspace bitfields.
2266 Delete unused subspace_index. All references now use the
2267 target_index field within the section structure itself.
2269 * som.c (make_unique_section): Delete unused declaration.
2270 (som_bfd_copy_private_bfd_data): New function.
2271 (som_object_setup): Allocate space for and save exec information
2272 that needs to be copied during objcopy/strip.
2273 (som_mkobject): Do not allocate space for a file header here.
2274 It is not used when only reading SOM objects.
2275 (som_prep_headers): Allocate space for and attach a file header
2276 to the output bfd. For executables, use the saved system_id
2277 value rather than trying to guess the right value. Do not abort
2278 wwhen setting file_hdr->entry* for executables.
2279 (som_begin_writing): For executables, set the exec_entry and
2281 (som_copy_private_backend_section_data): Always return a value.
2283 * libhppa.h (PA_PAGESIZE): Define.
2285 * som.c (SOM_ALIGN): Define.
2286 (som_begin_writing): If writing an executable, initialize all
2287 fields in the exec header to zero. Update fields in the exec
2288 header as sizes of loadable subspaces are computed. Carefully
2289 preserve alignments when building executables. Actually write the
2290 exec after all the fields are filled in.
2292 * Better long-filename handling. Reads SOM ABI compliant extended
2293 names, but doesn't quite write compliant extended names yet.
2294 * som.c (som_slurp_extended_name_table): Delete function. The
2295 generic code will handle things correctly.
2296 (som_slurp_armap): Seek to the beginning of the next member.
2297 (normalize): New function.
2298 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2299 name table into account when computing the file offsets in the
2300 SOM dictionary. Make sure to align to an even boundary.
2301 (som_write_armap): Initialize the checksum to zero.
2302 (ar_maxchars): Fix. Opps.
2304 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2306 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2307 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2309 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2311 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2312 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2313 * bfd-in2.h: Regenerated.
2315 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2316 this was also named trad_unix_bfd_copy_private_bfd_data.
2318 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2320 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2321 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2322 returns NULL, it is not an error. It's possible that some of
2323 these checks are not necessary (because the size can never be
2324 zero), but putting in the checks is the conservative thing to do
2325 in light of the fact that some of these malloc calls replaced
2326 unchecked alloca calls, in which a zero argument would work fine.
2328 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2330 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2331 duplicate definition.
2332 (osf_core_bfd_is_local_label): Define.
2334 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2335 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2336 failure indication, it merely means there are no relocs.
2338 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2339 after NAME, since SunOS /bin/cc can't handle it.
2341 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2343 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2344 From sukes@glue.umd.edu (Tasuki Hirata).
2346 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2348 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2349 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2350 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2352 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2354 * som.c (som_prep_for_fixups): Detect section symbols based
2355 on either the lack of private data or the symbol flags. Do not
2356 munge section symbol names anymore -- they no longer confuse GDB.
2357 (som_begin_writing): Leave space for an exec header if writing
2359 (som_slurp_symbol_table): Recognize both forms of section symbol
2360 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2361 section symbols to be the name of the section they represent.
2362 Debugging symbols begin with "L$0\001", not just "L$".
2364 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2366 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2368 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2369 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2370 and bfd_is_local_label.
2372 * targets.c: Add new entries to the bfd_target structure.
2374 * bfd.c (bfd_copy_private_bfd_data): New definition.
2376 * section.c (bfd_copy_private_section_data): New definition.
2378 * syms.c (bfd_is_local_label): New definition.
2380 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2382 * libbfd.c (bfd_generic_is_local_label): New function.
2384 * *-core.c: Provide default definitions for new functions in
2385 the target vector which all point to bfd_false.
2387 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2388 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2389 Default new vectors for copying private backend data to bfd_true.
2390 Default new vector for determining if a symbol is a local label
2391 to bfd_generic_is_local_label.
2393 * som.c (som_bfd_copy_private_section_data): New function.
2394 (som_bfd_is_local_label): New function.
2395 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2397 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2399 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2401 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2403 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2406 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2407 Indent some of them to GNU standards.
2409 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2410 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2411 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2412 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2413 Update copyright years.
2415 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2417 * som.c (som_prep_for_fixups): A relocation involving the section
2418 symbol for the *ABS* section is really a relocation involving
2420 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2421 undefined symbols. Correctly distinguish between debugger symbols
2422 and section symbols.
2424 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2425 for spaces and subspaces.
2427 * som.c (som_bfd_count_ar_symbols): Fix typo.
2429 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2430 HAS_RELOC based on the object's magic number.
2431 (make_unique_section): Delete function. BFD and its users are
2432 prepared to handle multiple sections with the same name.
2433 (setup_sections): Allocate space on the BFD's obstack to hold
2434 section names. Use bfd_make_setion_anyway rather than the
2435 obsolete make_unique_section.
2436 (som_prep_headers): Choose the correct SOM magic number based
2438 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2440 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2442 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2443 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2444 * Makefile.in, configure.in: Corresponding changes.
2446 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2448 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2450 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2452 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2453 is always located at the start of the data section to allow
2454 recovery of the dynamic info from a stripped executable.
2455 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2458 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2460 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2461 cruft (like the #pragma alloca for AIX).
2462 In addition to that problem, the C alloca calls xmalloc, which
2463 means checking for being out of memory can't work right. The
2464 following changes remove all uses of alloca from BFD.
2465 * hosts/solaris2.h: Remove alloca cruft.
2466 * som.c: Replace alloca with a fixed size auto array.
2467 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2468 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2469 sunos.c: Replace alloca with malloc and appropriate error checking and
2471 * linker.c: Replace alloca with obstack_alloc.
2472 * libbfd.h: Rebuilt.
2474 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2476 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2479 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2481 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2482 Elf*_Off typedefs by their expansion, the typedefs have been
2483 removed from include/elf/internal.h.
2484 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2485 SHT_PROGBITS section.
2487 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2489 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2493 * configure.host: Recognize i[34]86-sequent-*.
2495 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2496 return from bfd_seek indicates an error.
2497 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2498 TRAD_CORE_STACK_OFFSET.
2499 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2500 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2502 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2504 * som.[ch]: Do not include libhppa.h in som.c, instead include
2507 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2508 include it in elf32-hppa.h.
2510 * som.c (log2): Return -1 on error rather than aborting.
2511 (setup_sections): Bubble up an error from log2.
2513 * Changes to make HP C compiler happy in both traditional
2515 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2517 (bfd_som_set_section_attributes): Use unsigned int rather than
2518 unsigned char to avoid GNU-C extensions.
2519 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2520 or failure rather than aborting on failure.
2522 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2524 (bfd_som_attach_aux_hdr): Add prototype.
2525 (hppa_som-gen_reloc_type): Likewise.
2527 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2528 (hppa_look_for_stubs_in_section): Do not return false on failure
2529 until rest of code is ready to handle it. Abort for now.

2533 * bfd-in2.h: Rebuilt.
2535 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

2541 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
2543 * config.bfd : Add i386-os9k.
2544 * config/i386-os9k.mt : Newly add os9k target makefile.
2546 * i386os9k.c : new file to handle os9k format bfd.
2547 * Makefile.in : Handle new file i386os9k.c
2548 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2549 * cache.c : Initialize cache_sentinel to 0.

2553 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2554 action in case where caller specified no argument relocation.
2555 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2556 right in the original relocation and the stub's relocation.
2558 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2559 unused symbols argument.
2561 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2562 than asymbol * for original target symbol. All callers changed.
2563 Set reloc->sym_ptr_ptr appropriately.
2564 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2565 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2566 argument. Use the output symbols when canonicalizing the relocs,
2567 creating them if necessary.
2569 * linker.c (_bfd_generic_link_output_symbols): Do not
2570 rebuild/clobber the output symbols if they already exist.
2572 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2574 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2575 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2576 * bfd-in2.h: Rebuilt.
2578 * srec.c (hex_value): Always set to a size of 256 bytes.
2579 (srec_init): Cosmetic changes.
2581 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2583 * elf32-hppa.c: Second half of major cleanup. More comments,
2584 PARAMize and staticize rest of functions. Delete unused
2585 functions. Delete unused/unnecessary arguments to some functions.
2586 Group static vars together. Abort for bad errors until we have
2587 error code propogation working. Work on spacing and indention.
2588 Add FIXMEs for unresolved problems. Use enums rather than
2589 #defines for lots of things. Merge two functions which build
2590 linker stubs into a single function (so they can easily share a
2591 ton of common code).
2593 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2595 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2596 avoid depending upon right shifts of signed numbers, and to
2597 correct handling of src_mask with lower bits zero.
2599 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2600 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
2601 * elf32-i386.c: Likewise.
2602 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old

2815 bother processing them.

4805 terms of MY, because that causes a recusive invocation of CAT when
4806 expanded within JUMP_TABLE, and ANSI compilers don't expand
4808 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
4809 MY_reloc_howto_type_lookup, and don't define in terms of MY.
4810 (MY_canonicalize_reloc): Don't define in terms of MY.
4811 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
4812 than listing functions.
