889 (_bfd_generic_final_link): Account for link_order relocs when
890 allocating space for relocations. Handle them in link_order loop.
891 (_bfd_generic_reloc_link_order): New function.
892 (_bfd_default_link_order): If a reloc_link_order is seen here,
894 (_bfd_count_link_order_relocs): New function.
895 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
896 argument from declaration.
897 (_bfd_generic_reloc_link_order): Declare.
898 (_bfd_count_link_order_relocs): Declare.
900 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
901 call to _bfd_generic_link_add_one_symbol.
902 (NAME(aout,final_link)): Account for link_order relocs when
903 allocating space for relocations. Handle them after handling all
905 (aout_link_reloc_link_order): New function.
906 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
907 call to _bfd_generic_link_add_one_symbol.
908 (ecoff_bfd_final_link): Account for link_order relocs when
909 allocating space for relocations. Handle them in link_order loop.
910 (ecoff_link_write_external): Set the storage class of a defined
911 linker created symbol based on the section it is in. Correct
912 bfd_link_hash_weak case to use .sc rather than .st.
913 (ecoff_reloc_link_order): New function.
914 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
916 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
918 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
921 * cisco-core.c (cisco_core_file_p): Only pass one argument to
922 bfd_zmalloc. Free a pointer, not a union.
923 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
925 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
927 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
929 * som.c (bfd_section_from_som_symbol): Only to do the value
930 comparison for function symbols within executables.
932 * som.c (bfd_section_from_som_symbol): Renamed from
933 som_section_from_subspace_index. Pass in a native SOM symbol.
934 For executables, iterate through the sections to find out
935 which contains the symbol's address rather than using the
936 symbol_info field. (symbol_info has a different meaning for
937 dynamicly linked executables.)
939 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
942 * som.c (som_begin_writing): Fix braino (one call to align
943 space/subspace data was done unconditionally rather than
944 just for executables.)
946 * som.c (som_begin_writing): Align text in all executables to
947 make HPUX kernel happy. Fixes strip/objcopy for shared
950 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
952 * som.c (som_begin_writing): Account for alignment needs of
953 subspaces too when writing executables. Never request a negative
954 bss size. Fixes some problems with demand paged executables,
955 still having problems with pure executables and shared executables.
957 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
959 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
960 bfd_zalloc for rawptr, because later on we may call free, not
963 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
964 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
965 * cisco-core.c: New file.
966 * Makefile.in: Change accordingly.
967 * configure.in: Recognize cisco_core_vec.
968 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
969 * targets.c: Add cisco_core_vec.
970 * bfd-in2.h: Rebuilt.
972 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
974 * som.h (som_copyable_section_data_struct): New structure
975 containing all the private section information which needs
976 to be copied from input section to output section during
978 (som_section_data_struct): Remove several fields now in
979 som_copyable_section_data_struct. Make the space and
980 subspace dictionaries be pointers (to save space when
981 only reading objects).
983 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
984 some references changed. Allocate a copyable data stucture if
985 none exists. Store info into the copyable data structure.
986 (bfd_som_set_subsection_attributes): Likewise.
987 (som_is_space, som_is_subspace, som_is_container): New functions.
988 Use these instead of directly accessing private data.
989 (som_prep_headers): Allocate space and subspace headers here.
990 Fill in some fields in the space/subspace headers from the
992 (som_bfd_copy_private_section_data): Only copy the stuff
993 that we really need to make objcopy and strip work. Allocate
994 the copy_data structure for the output bfd before copying.
996 * som.h (struct som_exec_data): New structure to hold exec
997 info that must be preserved when running objcopy/strip.
998 (struct somdata): Add new "exec_data" field and accessor
999 macro. Add some comments on how the various fields are used.
1000 (som_section_data_struct): Make is_space and is_subspace bitfields.
1001 Delete unused subspace_index. All references now use the
1002 target_index field within the section structure itself.
1004 * som.c (make_unique_section): Delete unused declaration.
1005 (som_bfd_copy_private_bfd_data): New function.
1006 (som_object_setup): Allocate space for and save exec information
1007 that needs to be copied during objcopy/strip.
1008 (som_mkobject): Do not allocate space for a file header here.
1009 It is not used when only reading SOM objects.
1010 (som_prep_headers): Allocate space for and attach a file header
1011 to the output bfd. For executables, use the saved system_id
1012 value rather than trying to guess the right value. Do not abort
1013 wwhen setting file_hdr->entry* for executables.
1014 (som_begin_writing): For executables, set the exec_entry and
1016 (som_copy_private_backend_section_data): Always return a value.
1018 * libhppa.h (PA_PAGESIZE): Define.
1020 * som.c (SOM_ALIGN): Define.
1021 (som_begin_writing): If writing an executable, initialize all
1022 fields in the exec header to zero. Update fields in the exec
1023 header as sizes of loadable subspaces are computed. Carefully
1024 preserve alignments when building executables. Actually write the
1025 exec after all the fields are filled in.
1027 * Better long-filename handling. Reads SOM ABI compliant extended
1028 names, but doesn't quite write compliant extended names yet.
1029 * som.c (som_slurp_extended_name_table): Delete function. The
1030 generic code will handle things correctly.
1031 (som_slurp_armap): Seek to the beginning of the next member.
1032 (normalize): New function.
1033 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1034 name table into account when computing the file offsets in the
1035 SOM dictionary. Make sure to align to an even boundary.
1036 (som_write_armap): Initialize the checksum to zero.
1037 (ar_maxchars): Fix. Opps.
1039 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1041 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1042 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1044 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1046 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1047 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1048 * bfd-in2.h: Regenerated.
1050 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1051 this was also named trad_unix_bfd_copy_private_bfd_data.
1053 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1055 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1056 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1057 returns NULL, it is not an error. It's possible that some of
1058 these checks are not necessary (because the size can never be
1059 zero), but putting in the checks is the conservative thing to do
1060 in light of the fact that some of these malloc calls replaced
1061 unchecked alloca calls, in which a zero argument would work fine.
1063 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1065 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1066 duplicate definition.
1067 (osf_core_bfd_is_local_label): Define.
1069 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1070 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1071 failure indication, it merely means there are no relocs.
1073 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1074 after NAME, since SunOS /bin/cc can't handle it.
1076 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1078 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1079 From sukes@glue.umd.edu (Tasuki Hirata).
1081 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1083 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1084 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1085 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1087 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1089 * som.c (som_prep_for_fixups): Detect section symbols based
1090 on either the lack of private data or the symbol flags. Do not
1091 munge section symbol names anymore -- they no longer confuse GDB.
1092 (som_begin_writing): Leave space for an exec header if writing
1094 (som_slurp_symbol_table): Recognize both forms of section symbol
1095 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1096 section symbols to be the name of the section they represent.
1097 Debugging symbols begin with "L$0\001", not just "L$".
1099 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1101 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1103 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1104 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1105 and bfd_is_local_label.
1107 * targets.c: Add new entries to the bfd_target structure.
1109 * bfd.c (bfd_copy_private_bfd_data): New definition.
1111 * section.c (bfd_copy_private_section_data): New definition.
1113 * syms.c (bfd_is_local_label): New definition.
1115 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1117 * libbfd.c (bfd_generic_is_local_label): New function.
1119 * *-core.c: Provide default definitions for new functions in
1120 the target vector which all point to bfd_false.
1122 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1123 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1124 Default new vectors for copying private backend data to bfd_true.
1125 Default new vector for determining if a symbol is a local label
1126 to bfd_generic_is_local_label.
1128 * som.c (som_bfd_copy_private_section_data): New function.
1129 (som_bfd_is_local_label): New function.
1130 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1132 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1134 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1136 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1138 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1141 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1142 Indent some of them to GNU standards.
1144 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1145 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1146 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1147 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1148 Update copyright years.
1150 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1152 * som.c (som_prep_for_fixups): A relocation involving the section
1153 symbol for the *ABS* section is really a relocation involving
1155 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1156 undefined symbols. Correctly distinguish between debugger symbols
1157 and section symbols.
1159 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1160 for spaces and subspaces.
1162 * som.c (som_bfd_count_ar_symbols): Fix typo.
1164 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1165 HAS_RELOC based on the object's magic number.
1166 (make_unique_section): Delete function. BFD and its users are
1167 prepared to handle multiple sections with the same name.
1168 (setup_sections): Allocate space on the BFD's obstack to hold
1169 section names. Use bfd_make_setion_anyway rather than the
1170 obsolete make_unique_section.
1171 (som_prep_headers): Choose the correct SOM magic number based
1173 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1175 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1177 * elf32-ppc.c: Renamed from elf32-powerpc.c.
1178 start-sanitize-powerpc-netware
1179 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
1180 end-sanitize-powerpc-netware
1181 * Makefile.in, configure.in: Corresponding changes.
1183 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1185 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
1187 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1189 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1190 is always located at the start of the data section to allow
1191 recovery of the dynamic info from a stripped executable.
1192 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1195 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1197 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1198 cruft (like the #pragma alloca for AIX).
1199 In addition to that problem, the C alloca calls xmalloc, which
1200 means checking for being out of memory can't work right. The
1201 following changes remove all uses of alloca from BFD.
1202 * hosts/solaris2.h: Remove alloca cruft.
1203 * som.c: Replace alloca with a fixed size auto array.

1205 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
1206 sunos.c: Replace alloca with malloc and appropriate error checking and
1208 * linker.c: Replace alloca with obstack_alloc.
1209 * libbfd.h: Rebuilt.
1211 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1213 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1216 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1218 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1219 Elf*_Off typedefs by their expansion, the typedefs have been
1220 removed from include/elf/internal.h.
1221 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1222 SHT_PROGBITS section.
1224 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1226 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1232 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1233 return from bfd_seek indicates an error.
1234 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1235 TRAD_CORE_STACK_OFFSET.
1236 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1237 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1239 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1241 * som.[ch]: Do not include libhppa.h in som.c, instead include
1244 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1245 include it in elf32-hppa.h.
1247 * som.c (log2): Return -1 on error rather than aborting.
1248 (setup_sections): Bubble up an error from log2.
1250 * Changes to make HP C compiler happy in both traditional
1252 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1254 (bfd_som_set_section_attributes): Use unsigned int rather than
1255 unsigned char to avoid GNU-C extensions.
1256 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1257 or failure rather than aborting on failure.
1259 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1261 (bfd_som_attach_aux_hdr): Add prototype.
1262 (hppa_som-gen_reloc_type): Likewise.

1278 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
1280 * config.bfd : Add i386-os9k.
1281 * config/i386-os9k.mt : Newly add os9k target makefile.
1283 * i386os9k.c : new file to handle os9k format bfd.
1284 * Makefile.in : Handle new file i386os9k.c
1285 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
1286 * cache.c : Initialize cache_sentinel to 0.
1288 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1290 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
1291 action in case where caller specified no argument relocation.
1292 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
1293 right in the original relocation and the stub's relocation.
1295 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
1296 unused symbols argument.
1298 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
1299 than asymbol * for original target symbol. All callers changed.
1300 Set reloc->sym_ptr_ptr appropriately.
1301 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
1302 (hppa_elf_look_for_stubs_in_section): No longer need symbols
1303 argument. Use the output symbols when canonicalizing the relocs,
1304 creating them if necessary.
1306 * linker.c (_bfd_generic_link_output_symbols): Do not
1307 rebuild/clobber the output symbols if they already exist.
1309 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
1311 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
1312 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
1313 * bfd-in2.h: Rebuilt.
1315 * srec.c (hex_value): Always set to a size of 256 bytes.
1316 (srec_init): Cosmetic changes.
1318 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1320 * elf32-hppa.c: Second half of major cleanup. More comments,
1321 PARAMize and staticize rest of functions. Delete unused
1322 functions. Delete unused/unnecessary arguments to some functions.
1323 Group static vars together. Abort for bad errors until we have
1324 error code propogation working. Work on spacing and indention.
1325 Add FIXMEs for unresolved problems. Use enums rather than
1326 #defines for lots of things. Merge two functions which build
1327 linker stubs into a single function (so they can easily share a
1328 ton of common code).
1330 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
1332 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
1333 avoid depending upon right shifts of signed numbers, and to
1334 correct handling of src_mask with lower bits zero.
1336 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
1337 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3545 terms of MY, because that causes a recusive invocation of CAT when
3546 expanded within JUMP_TABLE, and ANSI compilers don't expand
3548 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
3549 MY_reloc_howto_type_lookup, and don't define in terms of MY.
3550 (MY_canonicalize_reloc): Don't define in terms of MY.
3551 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
3552 than listing functions.
