889 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
891 Support for link_order types which generate relocs in order to
892 support -Ur in the linker.
893 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
894 from call to _bfd_generic_link_add_one_symbol.
895 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
896 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
897 instead of bitsize to add_to_set call back.
898 (_bfd_generic_final_link): Account for link_order relocs when
899 allocating space for relocations. Handle them in link_order loop.
900 (_bfd_generic_reloc_link_order): New function.
901 (_bfd_default_link_order): If a reloc_link_order is seen here,
903 (_bfd_count_link_order_relocs): New function.
904 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
905 argument from declaration.
906 (_bfd_generic_reloc_link_order): Declare.
907 (_bfd_count_link_order_relocs): Declare.
909 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
910 call to _bfd_generic_link_add_one_symbol.
911 (NAME(aout,final_link)): Account for link_order relocs when
912 allocating space for relocations. Handle them after handling all
914 (aout_link_reloc_link_order): New function.
915 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
916 call to _bfd_generic_link_add_one_symbol.
917 (ecoff_bfd_final_link): Account for link_order relocs when
918 allocating space for relocations. Handle them in link_order loop.
919 (ecoff_link_write_external): Set the storage class of a defined
920 linker created symbol based on the section it is in. Correct
921 bfd_link_hash_weak case to use .sc rather than .st.
922 (ecoff_reloc_link_order): New function.
923 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
925 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
927 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
930 * cisco-core.c (cisco_core_file_p): Only pass one argument to
931 bfd_zmalloc. Free a pointer, not a union.
932 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
934 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
936 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
938 * som.c (bfd_section_from_som_symbol): Only to do the value
939 comparison for function symbols within executables.
941 * som.c (bfd_section_from_som_symbol): Renamed from
942 som_section_from_subspace_index. Pass in a native SOM symbol.
943 For executables, iterate through the sections to find out
944 which contains the symbol's address rather than using the
945 symbol_info field. (symbol_info has a different meaning for
946 dynamicly linked executables.)
948 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
951 * som.c (som_begin_writing): Fix braino (one call to align
952 space/subspace data was done unconditionally rather than
953 just for executables.)
955 * som.c (som_begin_writing): Align text in all executables to
956 make HPUX kernel happy. Fixes strip/objcopy for shared
959 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
961 * som.c (som_begin_writing): Account for alignment needs of
962 subspaces too when writing executables. Never request a negative
963 bss size. Fixes some problems with demand paged executables,
964 still having problems with pure executables and shared executables.
966 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
968 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
969 bfd_zalloc for rawptr, because later on we may call free, not
972 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
973 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
974 * cisco-core.c: New file.
975 * Makefile.in: Change accordingly.
976 * configure.in: Recognize cisco_core_vec.
977 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
978 * targets.c: Add cisco_core_vec.
979 * bfd-in2.h: Rebuilt.
981 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
983 * som.h (som_copyable_section_data_struct): New structure
984 containing all the private section information which needs
985 to be copied from input section to output section during
987 (som_section_data_struct): Remove several fields now in
988 som_copyable_section_data_struct. Make the space and
989 subspace dictionaries be pointers (to save space when
990 only reading objects).
992 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
993 some references changed. Allocate a copyable data stucture if
994 none exists. Store info into the copyable data structure.
995 (bfd_som_set_subsection_attributes): Likewise.
996 (som_is_space, som_is_subspace, som_is_container): New functions.
997 Use these instead of directly accessing private data.
998 (som_prep_headers): Allocate space and subspace headers here.
999 Fill in some fields in the space/subspace headers from the
1001 (som_bfd_copy_private_section_data): Only copy the stuff
1002 that we really need to make objcopy and strip work. Allocate
1003 the copy_data structure for the output bfd before copying.
1005 * som.h (struct som_exec_data): New structure to hold exec
1006 info that must be preserved when running objcopy/strip.
1007 (struct somdata): Add new "exec_data" field and accessor
1008 macro. Add some comments on how the various fields are used.
1009 (som_section_data_struct): Make is_space and is_subspace bitfields.
1010 Delete unused subspace_index. All references now use the
1011 target_index field within the section structure itself.
1013 * som.c (make_unique_section): Delete unused declaration.
1014 (som_bfd_copy_private_bfd_data): New function.
1015 (som_object_setup): Allocate space for and save exec information
1016 that needs to be copied during objcopy/strip.
1017 (som_mkobject): Do not allocate space for a file header here.
1018 It is not used when only reading SOM objects.
1019 (som_prep_headers): Allocate space for and attach a file header
1020 to the output bfd. For executables, use the saved system_id
1021 value rather than trying to guess the right value. Do not abort
1022 wwhen setting file_hdr->entry* for executables.
1023 (som_begin_writing): For executables, set the exec_entry and
1025 (som_copy_private_backend_section_data): Always return a value.
1027 * libhppa.h (PA_PAGESIZE): Define.
1029 * som.c (SOM_ALIGN): Define.
1030 (som_begin_writing): If writing an executable, initialize all
1031 fields in the exec header to zero. Update fields in the exec
1032 header as sizes of loadable subspaces are computed. Carefully
1033 preserve alignments when building executables. Actually write the
1034 exec after all the fields are filled in.
1036 * Better long-filename handling. Reads SOM ABI compliant extended
1037 names, but doesn't quite write compliant extended names yet.
1038 * som.c (som_slurp_extended_name_table): Delete function. The
1039 generic code will handle things correctly.
1040 (som_slurp_armap): Seek to the beginning of the next member.
1041 (normalize): New function.
1042 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1043 name table into account when computing the file offsets in the
1044 SOM dictionary. Make sure to align to an even boundary.
1045 (som_write_armap): Initialize the checksum to zero.
1046 (ar_maxchars): Fix. Opps.
1048 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1050 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1051 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1053 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1055 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1056 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1057 * bfd-in2.h: Regenerated.
1059 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1060 this was also named trad_unix_bfd_copy_private_bfd_data.
1062 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1064 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1065 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1066 returns NULL, it is not an error. It's possible that some of
1067 these checks are not necessary (because the size can never be
1068 zero), but putting in the checks is the conservative thing to do
1069 in light of the fact that some of these malloc calls replaced
1070 unchecked alloca calls, in which a zero argument would work fine.
1072 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1074 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1075 duplicate definition.
1076 (osf_core_bfd_is_local_label): Define.
1078 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1079 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1080 failure indication, it merely means there are no relocs.
1082 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1083 after NAME, since SunOS /bin/cc can't handle it.
1085 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1087 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1088 From sukes@glue.umd.edu (Tasuki Hirata).
1090 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1092 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1093 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1094 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1096 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1098 * som.c (som_prep_for_fixups): Detect section symbols based
1099 on either the lack of private data or the symbol flags. Do not
1100 munge section symbol names anymore -- they no longer confuse GDB.
1101 (som_begin_writing): Leave space for an exec header if writing
1103 (som_slurp_symbol_table): Recognize both forms of section symbol
1104 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1105 section symbols to be the name of the section they represent.
1106 Debugging symbols begin with "L$0\001", not just "L$".
1108 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1110 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1112 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1113 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1114 and bfd_is_local_label.
1116 * targets.c: Add new entries to the bfd_target structure.
1118 * bfd.c (bfd_copy_private_bfd_data): New definition.
1120 * section.c (bfd_copy_private_section_data): New definition.
1122 * syms.c (bfd_is_local_label): New definition.
1124 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1126 * libbfd.c (bfd_generic_is_local_label): New function.
1128 * *-core.c: Provide default definitions for new functions in
1129 the target vector which all point to bfd_false.
1131 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1132 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1133 Default new vectors for copying private backend data to bfd_true.
1134 Default new vector for determining if a symbol is a local label
1135 to bfd_generic_is_local_label.
1137 * som.c (som_bfd_copy_private_section_data): New function.
1138 (som_bfd_is_local_label): New function.
1139 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1141 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1143 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1145 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1147 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1150 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1151 Indent some of them to GNU standards.
1153 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1154 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1155 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1156 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1157 Update copyright years.
1159 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1161 * som.c (som_prep_for_fixups): A relocation involving the section
1162 symbol for the *ABS* section is really a relocation involving
1164 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1165 undefined symbols. Correctly distinguish between debugger symbols
1166 and section symbols.
1168 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1169 for spaces and subspaces.
1171 * som.c (som_bfd_count_ar_symbols): Fix typo.
1173 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1174 HAS_RELOC based on the object's magic number.
1175 (make_unique_section): Delete function. BFD and its users are
1176 prepared to handle multiple sections with the same name.
1177 (setup_sections): Allocate space on the BFD's obstack to hold
1178 section names. Use bfd_make_setion_anyway rather than the
1179 obsolete make_unique_section.
1180 (som_prep_headers): Choose the correct SOM magic number based
1182 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1184 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1186 * elf32-ppc.c: Renamed from elf32-powerpc.c.
1187 start-sanitize-powerpc-netware
1188 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
1189 end-sanitize-powerpc-netware
1190 * Makefile.in, configure.in: Corresponding changes.
1192 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1194 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
1196 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1198 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1199 is always located at the start of the data section to allow
1200 recovery of the dynamic info from a stripped executable.
1201 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1204 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1206 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1207 cruft (like the #pragma alloca for AIX).
1208 In addition to that problem, the C alloca calls xmalloc, which
1209 means checking for being out of memory can't work right. The
1210 following changes remove all uses of alloca from BFD.
1211 * hosts/solaris2.h: Remove alloca cruft.
1212 * som.c: Replace alloca with a fixed size auto array.
1213 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
1214 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
1215 sunos.c: Replace alloca with malloc and appropriate error checking and
1217 * linker.c: Replace alloca with obstack_alloc.
1218 * libbfd.h: Rebuilt.
1220 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1222 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1225 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1227 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1228 Elf*_Off typedefs by their expansion, the typedefs have been
1229 removed from include/elf/internal.h.
1230 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1231 SHT_PROGBITS section.
1233 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1235 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1239 * configure.host: Recognize i[34]86-sequent-*.
1241 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1242 return from bfd_seek indicates an error.
1243 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1244 TRAD_CORE_STACK_OFFSET.
1245 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1246 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1248 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1250 * som.[ch]: Do not include libhppa.h in som.c, instead include
1253 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1254 include it in elf32-hppa.h.
1256 * som.c (log2): Return -1 on error rather than aborting.
1257 (setup_sections): Bubble up an error from log2.
1259 * Changes to make HP C compiler happy in both traditional
1261 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1263 (bfd_som_set_section_attributes): Use unsigned int rather than
1264 unsigned char to avoid GNU-C extensions.
1265 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1266 or failure rather than aborting on failure.
1268 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1270 (bfd_som_attach_aux_hdr): Add prototype.
1271 (hppa_som-gen_reloc_type): Likewise.
1273 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
1274 (hppa_look_for_stubs_in_section): Do not return false on failure
1275 until rest of code is ready to handle it. Abort for now.
1277 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1279 * bfd-in2.h: Rebuilt.
1281 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

1284 * Makefile.in: delete an extra blank.
1285 * configure.in : Add i396os9k_vec.
1287 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
1289 * config.bfd : Add i386-os9k.
1290 * config/i386-os9k.mt : Newly add os9k target makefile.
1292 * i386os9k.c : new file to handle os9k format bfd.
1293 * Makefile.in : Handle new file i386os9k.c
1294 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
1295 * cache.c : Initialize cache_sentinel to 0.
1297 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1299 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
1300 action in case where caller specified no argument relocation.
1301 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
1302 right in the original relocation and the stub's relocation.
1304 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
1305 unused symbols argument.
1307 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
1308 than asymbol * for original target symbol. All callers changed.
1309 Set reloc->sym_ptr_ptr appropriately.
1310 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
1311 (hppa_elf_look_for_stubs_in_section): No longer need symbols
1312 argument. Use the output symbols when canonicalizing the relocs,
1313 creating them if necessary.
1315 * linker.c (_bfd_generic_link_output_symbols): Do not
1316 rebuild/clobber the output symbols if they already exist.
1318 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
1320 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
1321 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
1322 * bfd-in2.h: Rebuilt.
1324 * srec.c (hex_value): Always set to a size of 256 bytes.
1325 (srec_init): Cosmetic changes.
1327 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1329 * elf32-hppa.c: Second half of major cleanup. More comments,
1330 PARAMize and staticize rest of functions. Delete unused
1331 functions. Delete unused/unnecessary arguments to some functions.
1332 Group static vars together. Abort for bad errors until we have
1333 error code propogation working. Work on spacing and indention.
1334 Add FIXMEs for unresolved problems. Use enums rather than
1335 #defines for lots of things. Merge two functions which build
1336 linker stubs into a single function (so they can easily share a
1337 ton of common code).
1339 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
1341 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
1342 avoid depending upon right shifts of signed numbers, and to
1343 correct handling of src_mask with lower bits zero.
1345 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

1564 bother processing them.

3546 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
3547 MY_bfd_seclet_link): Define.
3548 (MY_bfd_reloc_type_lookup): Rename from
3549 MY_reloc_howto_type_lookup.
3550 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
3551 (MY(vec)): Use JUMP_TABLE rather than listing functions.
3552 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
3553 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
3554 terms of MY, because that causes a recusive invocation of CAT when
3555 expanded within JUMP_TABLE, and ANSI compilers don't expand
3557 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
3558 MY_reloc_howto_type_lookup, and don't define in terms of MY.
3559 (MY_canonicalize_reloc): Don't define in terms of MY.
3560 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
3561 than listing functions.
