893 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
895 * som.c (som_begin_writing): Account for alignment needs of
896 subspaces too when writing executables. Never request a negative
897 bss size. Fixes some problems with demand paged executables,
898 still having problems with pure executables and shared executables.
900 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
902 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
903 bfd_zalloc for rawptr, because later on we may call free, not
906 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
907 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
908 * cisco-core.c: New file.
909 * Makefile.in: Change accordingly.
910 * configure.in: Recognize cisco_core_vec.
911 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
912 * targets.c: Add cisco_core_vec.
913 * bfd-in2.h: Rebuilt.
915 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
917 * som.h (som_copyable_section_data_struct): New structure
918 containing all the private section information which needs
919 to be copied from input section to output section during
921 (som_section_data_struct): Remove several fields now in
922 som_copyable_section_data_struct. Make the space and
923 subspace dictionaries be pointers (to save space when
924 only reading objects).
926 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
927 some references changed. Allocate a copyable data stucture if
928 none exists. Store info into the copyable data structure.
929 (bfd_som_set_subsection_attributes): Likewise.
930 (som_is_space, som_is_subspace, som_is_container): New functions.
931 Use these instead of directly accessing private data.
932 (som_prep_headers): Allocate space and subspace headers here.
933 Fill in some fields in the space/subspace headers from the
935 (som_bfd_copy_private_section_data): Only copy the stuff
936 that we really need to make objcopy and strip work. Allocate
937 the copy_data structure for the output bfd before copying.
939 * som.h (struct som_exec_data): New structure to hold exec
940 info that must be preserved when running objcopy/strip.
941 (struct somdata): Add new "exec_data" field and accessor
942 macro. Add some comments on how the various fields are used.
943 (som_section_data_struct): Make is_space and is_subspace bitfields.
944 Delete unused subspace_index. All references now use the
945 target_index field within the section structure itself.
947 * som.c (make_unique_section): Delete unused declaration.
948 (som_bfd_copy_private_bfd_data): New function.
949 (som_object_setup): Allocate space for and save exec information
950 that needs to be copied during objcopy/strip.
951 (som_mkobject): Do not allocate space for a file header here.
952 It is not used when only reading SOM objects.
953 (som_prep_headers): Allocate space for and attach a file header
954 to the output bfd. For executables, use the saved system_id
955 value rather than trying to guess the right value. Do not abort
956 wwhen setting file_hdr->entry* for executables.
957 (som_begin_writing): For executables, set the exec_entry and
959 (som_copy_private_backend_section_data): Always return a value.
961 * libhppa.h (PA_PAGESIZE): Define.
963 * som.c (SOM_ALIGN): Define.
964 (som_begin_writing): If writing an executable, initialize all
965 fields in the exec header to zero. Update fields in the exec
966 header as sizes of loadable subspaces are computed. Carefully
967 preserve alignments when building executables. Actually write the
968 exec after all the fields are filled in.
970 * Better long-filename handling. Reads SOM ABI compliant extended
971 names, but doesn't quite write compliant extended names yet.
972 * som.c (som_slurp_extended_name_table): Delete function. The
973 generic code will handle things correctly.
974 (som_slurp_armap): Seek to the beginning of the next member.
975 (normalize): New function.
976 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
977 name table into account when computing the file offsets in the
978 SOM dictionary. Make sure to align to an even boundary.
979 (som_write_armap): Initialize the checksum to zero.
980 (ar_maxchars): Fix. Opps.
982 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
984 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
985 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
987 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
989 * bfd-in.h (BFD_VERSION): Use @VERSION@.
990 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
991 * bfd-in2.h: Regenerated.
993 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
994 this was also named trad_unix_bfd_copy_private_bfd_data.
996 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
998 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
999 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1000 returns NULL, it is not an error. It's possible that some of
1001 these checks are not necessary (because the size can never be
1002 zero), but putting in the checks is the conservative thing to do
1003 in light of the fact that some of these malloc calls replaced
1004 unchecked alloca calls, in which a zero argument would work fine.
1006 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1008 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1009 duplicate definition.
1010 (osf_core_bfd_is_local_label): Define.
1012 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1013 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1014 failure indication, it merely means there are no relocs.
1016 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1017 after NAME, since SunOS /bin/cc can't handle it.
1019 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1021 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1022 From sukes@glue.umd.edu (Tasuki Hirata).
1024 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1026 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1027 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1028 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1030 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1032 * som.c (som_prep_for_fixups): Detect section symbols based
1033 on either the lack of private data or the symbol flags. Do not
1034 munge section symbol names anymore -- they no longer confuse GDB.
1035 (som_begin_writing): Leave space for an exec header if writing
1037 (som_slurp_symbol_table): Recognize both forms of section symbol
1038 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1039 section symbols to be the name of the section they represent.
1040 Debugging symbols begin with "L$0\001", not just "L$".
1042 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1044 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1046 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1047 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1048 and bfd_is_local_label.
1050 * targets.c: Add new entries to the bfd_target structure.
1052 * bfd.c (bfd_copy_private_bfd_data): New definition.

1062 * *-core.c: Provide default definitions for new functions in
1063 the target vector which all point to bfd_false.
1065 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1066 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1067 Default new vectors for copying private backend data to bfd_true.
1068 Default new vector for determining if a symbol is a local label
1069 to bfd_generic_is_local_label.
1071 * som.c (som_bfd_copy_private_section_data): New function.
1072 (som_bfd_is_local_label): New function.
1073 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1075 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1077 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1079 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1081 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1084 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1085 Indent some of them to GNU standards.
1087 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1088 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1089 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1090 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1091 Update copyright years.
1093 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1095 * som.c (som_prep_for_fixups): A relocation involving the section
1096 symbol for the *ABS* section is really a relocation involving
1098 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1099 undefined symbols. Correctly distinguish between debugger symbols
1100 and section symbols.
1102 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1103 for spaces and subspaces.
1105 * som.c (som_bfd_count_ar_symbols): Fix typo.
1107 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1108 HAS_RELOC based on the object's magic number.
1109 (make_unique_section): Delete function. BFD and its users are
1110 prepared to handle multiple sections with the same name.
1111 (setup_sections): Allocate space on the BFD's obstack to hold
1112 section names. Use bfd_make_setion_anyway rather than the
1113 obsolete make_unique_section.
1114 (som_prep_headers): Choose the correct SOM magic number based
1116 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1118 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

1132 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1133 is always located at the start of the data section to allow
1134 recovery of the dynamic info from a stripped executable.

1138 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1140 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1141 cruft (like the #pragma alloca for AIX).
1142 In addition to that problem, the C alloca calls xmalloc, which
1143 means checking for being out of memory can't work right. The
1144 following changes remove all uses of alloca from BFD.
1145 * hosts/solaris2.h: Remove alloca cruft.
1146 * som.c: Replace alloca with a fixed size auto array.

1151 * linker.c: Replace alloca with obstack_alloc.
1152 * libbfd.h: Rebuilt.
1154 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1156 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1159 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1161 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1162 Elf*_Off typedefs by their expansion, the typedefs have been
1163 removed from include/elf/internal.h.
1164 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1165 SHT_PROGBITS section.

1176 return from bfd_seek indicates an error.
1177 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1178 TRAD_CORE_STACK_OFFSET.
1179 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1180 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1182 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1184 * som.[ch]: Do not include libhppa.h in som.c, instead include
1187 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1188 include it in elf32-hppa.h.
1190 * som.c (log2): Return -1 on error rather than aborting.
1191 (setup_sections): Bubble up an error from log2.
1193 * Changes to make HP C compiler happy in both traditional
1195 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1197 (bfd_som_set_section_attributes): Use unsigned int rather than
1198 unsigned char to avoid GNU-C extensions.
1199 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1200 or failure rather than aborting on failure.
1202 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1204 (bfd_som_attach_aux_hdr): Add prototype.
1205 (hppa_som-gen_reloc_type): Likewise.

1234 action in case where caller specified no argument relocation.
1235 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
1236 right in the original relocation and the stub's relocation.
1238 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
1239 unused symbols argument.
1241 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
1242 than asymbol * for original target symbol. All callers changed.
1243 Set reloc->sym_ptr_ptr appropriately.
1244 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
1245 (hppa_elf_look_for_stubs_in_section): No longer need symbols
1246 argument. Use the output symbols when canonicalizing the relocs,
1247 creating them if necessary.
1249 * linker.c (_bfd_generic_link_output_symbols): Do not
1250 rebuild/clobber the output symbols if they already exist.
1252 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
1254 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

1256 * bfd-in2.h: Rebuilt.
1258 * srec.c (hex_value): Always set to a size of 256 bytes.
1259 (srec_init): Cosmetic changes.

1264 PARAMize and staticize rest of functions. Delete unused
1265 functions. Delete unused/unnecessary arguments to some functions.
1266 Group static vars together. Abort for bad errors until we have
1267 error code propogation working. Work on spacing and indention.
1268 Add FIXMEs for unresolved problems. Use enums rather than
1269 #defines for lots of things. Merge two functions which build
1270 linker stubs into a single function (so they can easily share a
1271 ton of common code).
1273 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
1275 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
1276 avoid depending upon right shifts of signed numbers, and to
1277 correct handling of src_mask with lower bits zero.

1307 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
1308 (elf_hppa_tc_make_sections): Likewise.
1309 (elf_hppa_final_processing): Add extern decl.
1311 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
1312 comments. PARAMize some static functions. Delete unused functions.
1313 Delete unused/unnecessary arguments to many functions. Group
1314 static vars together. Collapse common case statements together
1315 in many places. Use default case when possible instead of listing
1316 each case separately. Abort for bad errors until we get error
1317 code propogation working. Work on spacing and indention problems.
1318 Add FIXMEs for some unresolved problems. Delete hopelessly broken
1319 COMPLEX relocation support (it's never used anyway).
1320 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
1321 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
1322 (elf_hppa_tc_make_sections): Likewise.

2172 use get_value to get the symbol value and check for undefined
2174 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
2175 undefined, look it up in the linker hash table.
2177 * aoutx.h (translate_symbol_table): The string index 0 has a

2202 The sparc (and possibly other?) NLM format requires a different
2203 way to write exports, so add a write_export field to the backend
2204 data (and set it to NULL for everything but the sparc).
