903 * linker.c (generic_link_read_symbols): New function.
904 (generic_link_add_object_symbols): Use it. Use
905 _bfd_generic_link_get_symbols and _bfd_generic_link_get_symcount
906 to get the symbols from the BFD.
907 (generic_link_check_archive_element): Likewise.
908 (_bfd_generic_final_link): Likewise.

925 link_order loop. Use _bfd_generic_link_add_symbols_collect for
926 add_symbls entry point.
928 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
929 counting relocs. Set SEC_RELOC flag for any section which has
932 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
934 * linker.c (_bfd_generic_link_add_symbols): Just call
935 generic_link_add_symbols.
936 (_bfd_generic_link_add_symbols_collect): New function, like
937 _bfd_generic_link_add_symbols but also collect constructors and
938 destructors by name as collect2 does.
939 (generic_link_add_symbols): New function, like old

953 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
954 for first character in an extended name.
955 (_bfd_write_archive_contents): If ar_padchar == '/', then use
956 "//" as the name of the special archive member holding the
959 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
961 Support for link_order types which generate relocs in order to
962 support -Ur in the linker.
963 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
964 from call to _bfd_generic_link_add_one_symbol.
965 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
966 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
967 instead of bitsize to add_to_set call back.
968 (_bfd_generic_final_link): Account for link_order relocs when
969 allocating space for relocations. Handle them in link_order loop.
970 (_bfd_generic_reloc_link_order): New function.
971 (_bfd_default_link_order): If a reloc_link_order is seen here,
973 (_bfd_count_link_order_relocs): New function.
974 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
975 argument from declaration.

986 call to _bfd_generic_link_add_one_symbol.
987 (ecoff_bfd_final_link): Account for link_order relocs when
988 allocating space for relocations. Handle them in link_order loop.
989 (ecoff_link_write_external): Set the storage class of a defined
990 linker created symbol based on the section it is in. Correct
991 bfd_link_hash_weak case to use .sc rather than .st.
992 (ecoff_reloc_link_order): New function.
993 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
995 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1004 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1006 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1008 * som.c (bfd_section_from_som_symbol): Only to do the value
1009 comparison for function symbols within executables.
1011 * som.c (bfd_section_from_som_symbol): Renamed from
1012 som_section_from_subspace_index. Pass in a native SOM symbol.
1013 For executables, iterate through the sections to find out
1014 which contains the symbol's address rather than using the
1015 symbol_info field. (symbol_info has a different meaning for
1016 dynamicly linked executables.)
1018 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1021 * som.c (som_begin_writing): Fix braino (one call to align
1022 space/subspace data was done unconditionally rather than
1023 just for executables.)
1025 * som.c (som_begin_writing): Align text in all executables to
1026 make HPUX kernel happy. Fixes strip/objcopy for shared
1029 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1031 * som.c (som_begin_writing): Account for alignment needs of
1032 subspaces too when writing executables. Never request a negative
1033 bss size. Fixes some problems with demand paged executables,
1034 still having problems with pure executables and shared executables.
1036 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1038 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1039 bfd_zalloc for rawptr, because later on we may call free, not
1042 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1043 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1044 * cisco-core.c: New file.
1045 * Makefile.in: Change accordingly.
1046 * configure.in: Recognize cisco_core_vec.
1047 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1048 * targets.c: Add cisco_core_vec.
1049 * bfd-in2.h: Rebuilt.
1051 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1053 * som.h (som_copyable_section_data_struct): New structure
1054 containing all the private section information which needs
1055 to be copied from input section to output section during
1057 (som_section_data_struct): Remove several fields now in
1058 som_copyable_section_data_struct. Make the space and
1059 subspace dictionaries be pointers (to save space when
1060 only reading objects).
1062 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1063 some references changed. Allocate a copyable data stucture if
1064 none exists. Store info into the copyable data structure.
1065 (bfd_som_set_subsection_attributes): Likewise.
1066 (som_is_space, som_is_subspace, som_is_container): New functions.
1067 Use these instead of directly accessing private data.
1068 (som_prep_headers): Allocate space and subspace headers here.
1069 Fill in some fields in the space/subspace headers from the
1071 (som_bfd_copy_private_section_data): Only copy the stuff
1072 that we really need to make objcopy and strip work. Allocate
1073 the copy_data structure for the output bfd before copying.
1075 * som.h (struct som_exec_data): New structure to hold exec
1076 info that must be preserved when running objcopy/strip.
1077 (struct somdata): Add new "exec_data" field and accessor
1078 macro. Add some comments on how the various fields are used.
1079 (som_section_data_struct): Make is_space and is_subspace bitfields.
1080 Delete unused subspace_index. All references now use the
1081 target_index field within the section structure itself.
1083 * som.c (make_unique_section): Delete unused declaration.
1084 (som_bfd_copy_private_bfd_data): New function.
1085 (som_object_setup): Allocate space for and save exec information
1086 that needs to be copied during objcopy/strip.
1087 (som_mkobject): Do not allocate space for a file header here.
1088 It is not used when only reading SOM objects.
1089 (som_prep_headers): Allocate space for and attach a file header
1090 to the output bfd. For executables, use the saved system_id
1091 value rather than trying to guess the right value. Do not abort
1092 wwhen setting file_hdr->entry* for executables.
1093 (som_begin_writing): For executables, set the exec_entry and
1095 (som_copy_private_backend_section_data): Always return a value.
1097 * libhppa.h (PA_PAGESIZE): Define.
1099 * som.c (SOM_ALIGN): Define.
1100 (som_begin_writing): If writing an executable, initialize all
1101 fields in the exec header to zero. Update fields in the exec
1102 header as sizes of loadable subspaces are computed. Carefully
1103 preserve alignments when building executables. Actually write the
1104 exec after all the fields are filled in.
1106 * Better long-filename handling. Reads SOM ABI compliant extended
1107 names, but doesn't quite write compliant extended names yet.
1108 * som.c (som_slurp_extended_name_table): Delete function. The
1109 generic code will handle things correctly.
1110 (som_slurp_armap): Seek to the beginning of the next member.
1111 (normalize): New function.
1112 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1113 name table into account when computing the file offsets in the
1114 SOM dictionary. Make sure to align to an even boundary.
1115 (som_write_armap): Initialize the checksum to zero.
1116 (ar_maxchars): Fix. Opps.
1118 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1120 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1121 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1123 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1125 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1126 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1127 * bfd-in2.h: Regenerated.
1129 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1130 this was also named trad_unix_bfd_copy_private_bfd_data.
1132 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1134 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1135 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1136 returns NULL, it is not an error. It's possible that some of
1137 these checks are not necessary (because the size can never be
1138 zero), but putting in the checks is the conservative thing to do
1139 in light of the fact that some of these malloc calls replaced
1140 unchecked alloca calls, in which a zero argument would work fine.
1142 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1144 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1145 duplicate definition.
1146 (osf_core_bfd_is_local_label): Define.
1148 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1149 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1150 failure indication, it merely means there are no relocs.
1152 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1153 after NAME, since SunOS /bin/cc can't handle it.
1155 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1157 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1158 From sukes@glue.umd.edu (Tasuki Hirata).
1160 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1162 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1163 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1164 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1166 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1168 * som.c (som_prep_for_fixups): Detect section symbols based
1169 on either the lack of private data or the symbol flags. Do not
1170 munge section symbol names anymore -- they no longer confuse GDB.
1171 (som_begin_writing): Leave space for an exec header if writing
1173 (som_slurp_symbol_table): Recognize both forms of section symbol
1174 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1175 section symbols to be the name of the section they represent.
1176 Debugging symbols begin with "L$0\001", not just "L$".
1178 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1180 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1182 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1183 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1184 and bfd_is_local_label.
1186 * targets.c: Add new entries to the bfd_target structure.
1188 * bfd.c (bfd_copy_private_bfd_data): New definition.
1190 * section.c (bfd_copy_private_section_data): New definition.
1192 * syms.c (bfd_is_local_label): New definition.

1196 * libbfd.c (bfd_generic_is_local_label): New function.
1198 * *-core.c: Provide default definitions for new functions in
1199 the target vector which all point to bfd_false.
1201 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1202 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1203 Default new vectors for copying private backend data to bfd_true.
1204 Default new vector for determining if a symbol is a local label
1205 to bfd_generic_is_local_label.
1207 * som.c (som_bfd_copy_private_section_data): New function.
1208 (som_bfd_is_local_label): New function.
1209 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1211 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1213 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1215 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1217 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1220 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1221 Indent some of them to GNU standards.
1223 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1224 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1225 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1226 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1227 Update copyright years.
1229 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1231 * som.c (som_prep_for_fixups): A relocation involving the section
1232 symbol for the *ABS* section is really a relocation involving
1234 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1235 undefined symbols. Correctly distinguish between debugger symbols
1236 and section symbols.
1238 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1239 for spaces and subspaces.
1241 * som.c (som_bfd_count_ar_symbols): Fix typo.
1243 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1244 HAS_RELOC based on the object's magic number.
1245 (make_unique_section): Delete function. BFD and its users are
1246 prepared to handle multiple sections with the same name.
1247 (setup_sections): Allocate space on the BFD's obstack to hold
1248 section names. Use bfd_make_setion_anyway rather than the
1249 obsolete make_unique_section.
1250 (som_prep_headers): Choose the correct SOM magic number based
1252 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1254 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1256 * elf32-ppc.c: Renamed from elf32-powerpc.c.

1268 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1269 is always located at the start of the data section to allow
1270 recovery of the dynamic info from a stripped executable.
1271 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1274 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1276 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1277 cruft (like the #pragma alloca for AIX).
1278 In addition to that problem, the C alloca calls xmalloc, which
1279 means checking for being out of memory can't work right. The
1280 following changes remove all uses of alloca from BFD.
1281 * hosts/solaris2.h: Remove alloca cruft.
1282 * som.c: Replace alloca with a fixed size auto array.

1287 * linker.c: Replace alloca with obstack_alloc.
1288 * libbfd.h: Rebuilt.
1290 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1292 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1295 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1297 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1298 Elf*_Off typedefs by their expansion, the typedefs have been
1299 removed from include/elf/internal.h.
1300 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1301 SHT_PROGBITS section.
1303 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1305 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1309 * configure.host: Recognize i[34]86-sequent-*.
1311 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1312 return from bfd_seek indicates an error.
1313 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1314 TRAD_CORE_STACK_OFFSET.
1315 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1316 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1318 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1320 * som.[ch]: Do not include libhppa.h in som.c, instead include
1323 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1324 include it in elf32-hppa.h.
1326 * som.c (log2): Return -1 on error rather than aborting.
1327 (setup_sections): Bubble up an error from log2.
1329 * Changes to make HP C compiler happy in both traditional
1331 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1333 (bfd_som_set_section_attributes): Use unsigned int rather than
1334 unsigned char to avoid GNU-C extensions.
1335 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1336 or failure rather than aborting on failure.
1338 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1340 (bfd_som_attach_aux_hdr): Add prototype.
1341 (hppa_som-gen_reloc_type): Likewise.

1344 (hppa_look_for_stubs_in_section): Do not return false on failure
1345 until rest of code is ready to handle it. Abort for now.

1455 COMPLEX relocation support (it's never used anyway).
1456 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

1633 (b_out_relax_section): If a section contains no relocations, don't
1634 bother processing them.
1635 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2338 The sparc (and possibly other?) NLM format requires a different
2339 way to write exports, so add a write_export field to the backend
2340 data (and set it to NULL for everything but the sparc).
