2152 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2153 bfd_zmalloc. Free a pointer, not a union.
2154 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2156 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2158 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2160 * som.c (bfd_section_from_som_symbol): Only to do the value
2161 comparison for function symbols within executables.
2163 * som.c (bfd_section_from_som_symbol): Renamed from
2164 som_section_from_subspace_index. Pass in a native SOM symbol.
2165 For executables, iterate through the sections to find out
2166 which contains the symbol's address rather than using the
2167 symbol_info field. (symbol_info has a different meaning for
2168 dynamicly linked executables.)
2170 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2173 * som.c (som_begin_writing): Fix braino (one call to align
2174 space/subspace data was done unconditionally rather than
2175 just for executables.)
2177 * som.c (som_begin_writing): Align text in all executables to
2178 make HPUX kernel happy. Fixes strip/objcopy for shared
2181 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2183 * som.c (som_begin_writing): Account for alignment needs of
2184 subspaces too when writing executables. Never request a negative
2185 bss size. Fixes some problems with demand paged executables,
2186 still having problems with pure executables and shared executables.
2188 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2190 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2191 bfd_zalloc for rawptr, because later on we may call free, not
2194 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2195 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2196 * cisco-core.c: New file.
2197 * Makefile.in: Change accordingly.
2198 * configure.in: Recognize cisco_core_vec.
2199 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2200 * targets.c: Add cisco_core_vec.
2201 * bfd-in2.h: Rebuilt.
2203 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2205 * som.h (som_copyable_section_data_struct): New structure
2206 containing all the private section information which needs
2207 to be copied from input section to output section during
2209 (som_section_data_struct): Remove several fields now in
2210 som_copyable_section_data_struct. Make the space and
2211 subspace dictionaries be pointers (to save space when
2212 only reading objects).
2214 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2215 some references changed. Allocate a copyable data stucture if
2216 none exists. Store info into the copyable data structure.
2217 (bfd_som_set_subsection_attributes): Likewise.
2218 (som_is_space, som_is_subspace, som_is_container): New functions.
2219 Use these instead of directly accessing private data.
2220 (som_prep_headers): Allocate space and subspace headers here.
2221 Fill in some fields in the space/subspace headers from the
2223 (som_bfd_copy_private_section_data): Only copy the stuff
2224 that we really need to make objcopy and strip work. Allocate
2225 the copy_data structure for the output bfd before copying.
2227 * som.h (struct som_exec_data): New structure to hold exec
2228 info that must be preserved when running objcopy/strip.
2229 (struct somdata): Add new "exec_data" field and accessor
2230 macro. Add some comments on how the various fields are used.
2231 (som_section_data_struct): Make is_space and is_subspace bitfields.
2232 Delete unused subspace_index. All references now use the
2233 target_index field within the section structure itself.
2235 * som.c (make_unique_section): Delete unused declaration.
2236 (som_bfd_copy_private_bfd_data): New function.
2237 (som_object_setup): Allocate space for and save exec information
2238 that needs to be copied during objcopy/strip.
2239 (som_mkobject): Do not allocate space for a file header here.
2240 It is not used when only reading SOM objects.
2241 (som_prep_headers): Allocate space for and attach a file header
2242 to the output bfd. For executables, use the saved system_id
2243 value rather than trying to guess the right value. Do not abort
2244 wwhen setting file_hdr->entry* for executables.
2245 (som_begin_writing): For executables, set the exec_entry and
2247 (som_copy_private_backend_section_data): Always return a value.
2249 * libhppa.h (PA_PAGESIZE): Define.
2251 * som.c (SOM_ALIGN): Define.
2252 (som_begin_writing): If writing an executable, initialize all
2253 fields in the exec header to zero. Update fields in the exec
2254 header as sizes of loadable subspaces are computed. Carefully
2255 preserve alignments when building executables. Actually write the
2256 exec after all the fields are filled in.
2258 * Better long-filename handling. Reads SOM ABI compliant extended
2259 names, but doesn't quite write compliant extended names yet.
2260 * som.c (som_slurp_extended_name_table): Delete function. The
2261 generic code will handle things correctly.
2262 (som_slurp_armap): Seek to the beginning of the next member.
2263 (normalize): New function.
2264 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2265 name table into account when computing the file offsets in the
2266 SOM dictionary. Make sure to align to an even boundary.
2267 (som_write_armap): Initialize the checksum to zero.
2268 (ar_maxchars): Fix. Opps.
2270 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2272 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2273 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2275 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2277 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2278 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2279 * bfd-in2.h: Regenerated.
2281 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2282 this was also named trad_unix_bfd_copy_private_bfd_data.
2284 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2286 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2287 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2288 returns NULL, it is not an error. It's possible that some of
2289 these checks are not necessary (because the size can never be
2290 zero), but putting in the checks is the conservative thing to do
2291 in light of the fact that some of these malloc calls replaced
2292 unchecked alloca calls, in which a zero argument would work fine.
2294 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2296 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2297 duplicate definition.
2298 (osf_core_bfd_is_local_label): Define.
2300 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2301 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2302 failure indication, it merely means there are no relocs.
2304 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2305 after NAME, since SunOS /bin/cc can't handle it.
2307 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2309 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2310 From sukes@glue.umd.edu (Tasuki Hirata).
2312 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2314 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2315 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2316 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2318 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2320 * som.c (som_prep_for_fixups): Detect section symbols based
2321 on either the lack of private data or the symbol flags. Do not
2322 munge section symbol names anymore -- they no longer confuse GDB.
2323 (som_begin_writing): Leave space for an exec header if writing
2325 (som_slurp_symbol_table): Recognize both forms of section symbol
2326 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2327 section symbols to be the name of the section they represent.
2328 Debugging symbols begin with "L$0\001", not just "L$".
2330 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2332 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2334 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2335 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2336 and bfd_is_local_label.
2338 * targets.c: Add new entries to the bfd_target structure.
2340 * bfd.c (bfd_copy_private_bfd_data): New definition.
2342 * section.c (bfd_copy_private_section_data): New definition.
2344 * syms.c (bfd_is_local_label): New definition.
2346 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2348 * libbfd.c (bfd_generic_is_local_label): New function.
2350 * *-core.c: Provide default definitions for new functions in
2351 the target vector which all point to bfd_false.
2353 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2354 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2355 Default new vectors for copying private backend data to bfd_true.
2356 Default new vector for determining if a symbol is a local label
2357 to bfd_generic_is_local_label.
2359 * som.c (som_bfd_copy_private_section_data): New function.
2360 (som_bfd_is_local_label): New function.
2361 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2363 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2365 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2367 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2369 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2372 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2373 Indent some of them to GNU standards.
2375 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2376 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2377 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2378 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2379 Update copyright years.
2381 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2383 * som.c (som_prep_for_fixups): A relocation involving the section
2384 symbol for the *ABS* section is really a relocation involving
2386 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2387 undefined symbols. Correctly distinguish between debugger symbols
2388 and section symbols.
2390 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2391 for spaces and subspaces.
2393 * som.c (som_bfd_count_ar_symbols): Fix typo.
2395 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2396 HAS_RELOC based on the object's magic number.
2397 (make_unique_section): Delete function. BFD and its users are
2398 prepared to handle multiple sections with the same name.
2399 (setup_sections): Allocate space on the BFD's obstack to hold
2400 section names. Use bfd_make_setion_anyway rather than the
2401 obsolete make_unique_section.
2402 (som_prep_headers): Choose the correct SOM magic number based
2404 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2406 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2408 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2409 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2410 * Makefile.in, configure.in: Corresponding changes.
2412 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2414 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2416 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2418 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2419 is always located at the start of the data section to allow
2420 recovery of the dynamic info from a stripped executable.
2421 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2424 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2426 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2427 cruft (like the #pragma alloca for AIX).
2428 In addition to that problem, the C alloca calls xmalloc, which
2429 means checking for being out of memory can't work right. The
2430 following changes remove all uses of alloca from BFD.
2431 * hosts/solaris2.h: Remove alloca cruft.
2432 * som.c: Replace alloca with a fixed size auto array.
2433 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2434 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2435 sunos.c: Replace alloca with malloc and appropriate error checking and
2437 * linker.c: Replace alloca with obstack_alloc.
2438 * libbfd.h: Rebuilt.
2440 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2442 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2445 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2447 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2448 Elf*_Off typedefs by their expansion, the typedefs have been
2449 removed from include/elf/internal.h.
2450 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2451 SHT_PROGBITS section.
2453 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2455 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2459 * configure.host: Recognize i[34]86-sequent-*.
2461 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2462 return from bfd_seek indicates an error.
2463 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2464 TRAD_CORE_STACK_OFFSET.
2465 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2466 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2468 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2470 * som.[ch]: Do not include libhppa.h in som.c, instead include
2473 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2474 include it in elf32-hppa.h.
2476 * som.c (log2): Return -1 on error rather than aborting.
2477 (setup_sections): Bubble up an error from log2.
2479 * Changes to make HP C compiler happy in both traditional
2481 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2483 (bfd_som_set_section_attributes): Use unsigned int rather than
2484 unsigned char to avoid GNU-C extensions.
2485 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2486 or failure rather than aborting on failure.
2488 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2490 (bfd_som_attach_aux_hdr): Add prototype.
2491 (hppa_som-gen_reloc_type): Likewise.
2493 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2494 (hppa_look_for_stubs_in_section): Do not return false on failure
2495 until rest of code is ready to handle it. Abort for now.
2497 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2499 * bfd-in2.h: Rebuilt.
2501 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
2503 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

2507 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
2509 * config.bfd : Add i386-os9k.
2510 * config/i386-os9k.mt : Newly add os9k target makefile.
2512 * i386os9k.c : new file to handle os9k format bfd.
2513 * Makefile.in : Handle new file i386os9k.c
2514 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2515 * cache.c : Initialize cache_sentinel to 0.

2519 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2520 action in case where caller specified no argument relocation.
2521 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2522 right in the original relocation and the stub's relocation.
2524 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2525 unused symbols argument.
2527 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2528 than asymbol * for original target symbol. All callers changed.
2529 Set reloc->sym_ptr_ptr appropriately.
2530 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2531 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2532 argument. Use the output symbols when canonicalizing the relocs,
2533 creating them if necessary.
2535 * linker.c (_bfd_generic_link_output_symbols): Do not
2536 rebuild/clobber the output symbols if they already exist.
2538 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2540 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2541 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2542 * bfd-in2.h: Rebuilt.
2544 * srec.c (hex_value): Always set to a size of 256 bytes.
2545 (srec_init): Cosmetic changes.
2547 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2549 * elf32-hppa.c: Second half of major cleanup. More comments,
2550 PARAMize and staticize rest of functions. Delete unused
2551 functions. Delete unused/unnecessary arguments to some functions.
2552 Group static vars together. Abort for bad errors until we have
2553 error code propogation working. Work on spacing and indention.
2554 Add FIXMEs for unresolved problems. Use enums rather than
2555 #defines for lots of things. Merge two functions which build
2556 linker stubs into a single function (so they can easily share a
2557 ton of common code).
2559 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2561 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2562 avoid depending upon right shifts of signed numbers, and to
2563 correct handling of src_mask with lower bits zero.
2565 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2566 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

2572 (assign_file_positions_except_relocs): Make i unsigned.
2573 (write_shdrs_and_ehdr): Make count unsigned.
2574 (assign_file_positions_for_relocs): Make i unsigned.
2575 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
2576 (section_from_elf_index): Make index argument unsigned.
2578 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
2580 * elfcode.h: Don't include assert.h.
2581 (swap_out_syms): Use BFD_ASSERT rather than assert.
2583 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
2586 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
2589 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2591 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
2593 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
2594 (elf_hppa_tc_make_sections): Likewise.
2595 (elf_hppa_final_processing): Add extern decl.
2597 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
2598 comments. PARAMize some static functions. Delete unused functions.
2599 Delete unused/unnecessary arguments to many functions. Group
2600 static vars together. Collapse common case statements together
2601 in many places. Use default case when possible instead of listing
2602 each case separately. Abort for bad errors until we get error
2603 code propogation working. Work on spacing and indention problems.
2604 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2605 COMPLEX relocation support (it's never used anyway).
2606 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3451 the symbol value and check for undefined symbols.
3452 (get_value): If the symbol is undefined, look it up in the linker
3454 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
3455 use get_value to get the symbol value and check for undefined
3457 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3458 undefined, look it up in the linker hash table.
3460 * aoutx.h (translate_symbol_table): The string index 0 has a

3485 The sparc (and possibly other?) NLM format requires a different
3486 way to write exports, so add a write_export field to the backend
3487 data (and set it to NULL for everything but the sparc).
