890 destructors by name as collect2 does.
891 (generic_link_add_symbols): New function, like old
892 _bfd_generic_link_add_symbols but with collect argument.
893 (generic_link_add_object_symbols): Take collect argument.
894 (generic_link_check_archive_element_no_collect): New function.

903 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
905 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
906 for first character in an extended name.
907 (_bfd_write_archive_contents): If ar_padchar == '/', then use
908 "//" as the name of the special archive member holding the
911 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
913 Support for link_order types which generate relocs in order to
914 support -Ur in the linker.
915 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
916 from call to _bfd_generic_link_add_one_symbol.
917 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
918 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
919 instead of bitsize to add_to_set call back.
920 (_bfd_generic_final_link): Account for link_order relocs when
921 allocating space for relocations. Handle them in link_order loop.
922 (_bfd_generic_reloc_link_order): New function.
923 (_bfd_default_link_order): If a reloc_link_order is seen here,
925 (_bfd_count_link_order_relocs): New function.
926 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
927 argument from declaration.
928 (_bfd_generic_reloc_link_order): Declare.
929 (_bfd_count_link_order_relocs): Declare.

932 call to _bfd_generic_link_add_one_symbol.
933 (NAME(aout,final_link)): Account for link_order relocs when

936 (aout_link_reloc_link_order): New function.
937 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
938 call to _bfd_generic_link_add_one_symbol.
939 (ecoff_bfd_final_link): Account for link_order relocs when
940 allocating space for relocations. Handle them in link_order loop.
941 (ecoff_link_write_external): Set the storage class of a defined
942 linker created symbol based on the section it is in. Correct
943 bfd_link_hash_weak case to use .sc rather than .st.
944 (ecoff_reloc_link_order): New function.
945 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
947 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
949 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
952 * cisco-core.c (cisco_core_file_p): Only pass one argument to
953 bfd_zmalloc. Free a pointer, not a union.
954 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
956 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
958 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
960 * som.c (bfd_section_from_som_symbol): Only to do the value
961 comparison for function symbols within executables.
963 * som.c (bfd_section_from_som_symbol): Renamed from
964 som_section_from_subspace_index. Pass in a native SOM symbol.
965 For executables, iterate through the sections to find out
966 which contains the symbol's address rather than using the
967 symbol_info field. (symbol_info has a different meaning for
968 dynamicly linked executables.)
970 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
973 * som.c (som_begin_writing): Fix braino (one call to align
974 space/subspace data was done unconditionally rather than
975 just for executables.)
977 * som.c (som_begin_writing): Align text in all executables to
978 make HPUX kernel happy. Fixes strip/objcopy for shared
981 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
983 * som.c (som_begin_writing): Account for alignment needs of
984 subspaces too when writing executables. Never request a negative
985 bss size. Fixes some problems with demand paged executables,
986 still having problems with pure executables and shared executables.
988 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
990 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
991 bfd_zalloc for rawptr, because later on we may call free, not
994 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
995 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
996 * cisco-core.c: New file.
997 * Makefile.in: Change accordingly.
998 * configure.in: Recognize cisco_core_vec.
999 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1000 * targets.c: Add cisco_core_vec.
1001 * bfd-in2.h: Rebuilt.
1003 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1005 * som.h (som_copyable_section_data_struct): New structure
1006 containing all the private section information which needs
1007 to be copied from input section to output section during
1009 (som_section_data_struct): Remove several fields now in
1010 som_copyable_section_data_struct. Make the space and
1011 subspace dictionaries be pointers (to save space when
1012 only reading objects).
1014 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1015 some references changed. Allocate a copyable data stucture if
1016 none exists. Store info into the copyable data structure.
1017 (bfd_som_set_subsection_attributes): Likewise.
1018 (som_is_space, som_is_subspace, som_is_container): New functions.
1019 Use these instead of directly accessing private data.
1020 (som_prep_headers): Allocate space and subspace headers here.
1021 Fill in some fields in the space/subspace headers from the
1023 (som_bfd_copy_private_section_data): Only copy the stuff
1024 that we really need to make objcopy and strip work. Allocate
1025 the copy_data structure for the output bfd before copying.
1027 * som.h (struct som_exec_data): New structure to hold exec
1028 info that must be preserved when running objcopy/strip.
1029 (struct somdata): Add new "exec_data" field and accessor
1030 macro. Add some comments on how the various fields are used.
1031 (som_section_data_struct): Make is_space and is_subspace bitfields.
1032 Delete unused subspace_index. All references now use the
1033 target_index field within the section structure itself.
1035 * som.c (make_unique_section): Delete unused declaration.
1036 (som_bfd_copy_private_bfd_data): New function.
1037 (som_object_setup): Allocate space for and save exec information
1038 that needs to be copied during objcopy/strip.
1039 (som_mkobject): Do not allocate space for a file header here.
1040 It is not used when only reading SOM objects.
1041 (som_prep_headers): Allocate space for and attach a file header
1042 to the output bfd. For executables, use the saved system_id
1043 value rather than trying to guess the right value. Do not abort
1044 wwhen setting file_hdr->entry* for executables.
1045 (som_begin_writing): For executables, set the exec_entry and
1047 (som_copy_private_backend_section_data): Always return a value.
1049 * libhppa.h (PA_PAGESIZE): Define.
1051 * som.c (SOM_ALIGN): Define.
1052 (som_begin_writing): If writing an executable, initialize all
1053 fields in the exec header to zero. Update fields in the exec
1054 header as sizes of loadable subspaces are computed. Carefully
1055 preserve alignments when building executables. Actually write the
1056 exec after all the fields are filled in.
1058 * Better long-filename handling. Reads SOM ABI compliant extended
1059 names, but doesn't quite write compliant extended names yet.
1060 * som.c (som_slurp_extended_name_table): Delete function. The
1061 generic code will handle things correctly.
1062 (som_slurp_armap): Seek to the beginning of the next member.
1063 (normalize): New function.
1064 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1065 name table into account when computing the file offsets in the
1066 SOM dictionary. Make sure to align to an even boundary.
1067 (som_write_armap): Initialize the checksum to zero.
1068 (ar_maxchars): Fix. Opps.
1070 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1072 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1073 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

1077 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1078 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1079 * bfd-in2.h: Regenerated.
1081 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1082 this was also named trad_unix_bfd_copy_private_bfd_data.
1084 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1086 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1087 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1088 returns NULL, it is not an error. It's possible that some of
1089 these checks are not necessary (because the size can never be
1090 zero), but putting in the checks is the conservative thing to do
1091 in light of the fact that some of these malloc calls replaced
1092 unchecked alloca calls, in which a zero argument would work fine.
1094 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1096 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1097 duplicate definition.
1098 (osf_core_bfd_is_local_label): Define.
1100 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1101 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1102 failure indication, it merely means there are no relocs.
1104 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1105 after NAME, since SunOS /bin/cc can't handle it.
1107 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1109 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1110 From sukes@glue.umd.edu (Tasuki Hirata).
1112 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1114 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1115 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1116 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1118 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1120 * som.c (som_prep_for_fixups): Detect section symbols based
1121 on either the lack of private data or the symbol flags. Do not
1122 munge section symbol names anymore -- they no longer confuse GDB.
1123 (som_begin_writing): Leave space for an exec header if writing
1125 (som_slurp_symbol_table): Recognize both forms of section symbol
1126 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1127 section symbols to be the name of the section they represent.
1128 Debugging symbols begin with "L$0\001", not just "L$".
1130 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1132 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1134 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1135 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1136 and bfd_is_local_label.
1138 * targets.c: Add new entries to the bfd_target structure.
1140 * bfd.c (bfd_copy_private_bfd_data): New definition.
1142 * section.c (bfd_copy_private_section_data): New definition.
1144 * syms.c (bfd_is_local_label): New definition.
1146 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1148 * libbfd.c (bfd_generic_is_local_label): New function.
1150 * *-core.c: Provide default definitions for new functions in
1151 the target vector which all point to bfd_false.
1153 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1154 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1155 Default new vectors for copying private backend data to bfd_true.
1156 Default new vector for determining if a symbol is a local label
1157 to bfd_generic_is_local_label.
1159 * som.c (som_bfd_copy_private_section_data): New function.
1160 (som_bfd_is_local_label): New function.
1161 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1163 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1165 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1167 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1169 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1172 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1173 Indent some of them to GNU standards.
1175 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1176 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1177 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1178 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1179 Update copyright years.
1181 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1183 * som.c (som_prep_for_fixups): A relocation involving the section
1184 symbol for the *ABS* section is really a relocation involving
1186 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1187 undefined symbols. Correctly distinguish between debugger symbols
1188 and section symbols.
1190 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1191 for spaces and subspaces.
1193 * som.c (som_bfd_count_ar_symbols): Fix typo.
1195 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1196 HAS_RELOC based on the object's magic number.
1197 (make_unique_section): Delete function. BFD and its users are
1198 prepared to handle multiple sections with the same name.
1199 (setup_sections): Allocate space on the BFD's obstack to hold
1200 section names. Use bfd_make_setion_anyway rather than the
1201 obsolete make_unique_section.
1202 (som_prep_headers): Choose the correct SOM magic number based
1204 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1206 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

1220 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1221 is always located at the start of the data section to allow
1222 recovery of the dynamic info from a stripped executable.
1223 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1226 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1228 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1229 cruft (like the #pragma alloca for AIX).
1230 In addition to that problem, the C alloca calls xmalloc, which
1231 means checking for being out of memory can't work right. The
1232 following changes remove all uses of alloca from BFD.
1233 * hosts/solaris2.h: Remove alloca cruft.
1234 * som.c: Replace alloca with a fixed size auto array.

1244 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1247 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1249 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1250 Elf*_Off typedefs by their expansion, the typedefs have been
1251 removed from include/elf/internal.h.
1252 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1253 SHT_PROGBITS section.

1263 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1264 return from bfd_seek indicates an error.
1265 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1266 TRAD_CORE_STACK_OFFSET.
1267 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1268 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1270 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1272 * som.[ch]: Do not include libhppa.h in som.c, instead include
1275 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1276 include it in elf32-hppa.h.
1278 * som.c (log2): Return -1 on error rather than aborting.
1279 (setup_sections): Bubble up an error from log2.
1281 * Changes to make HP C compiler happy in both traditional
1283 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1285 (bfd_som_set_section_attributes): Use unsigned int rather than
1286 unsigned char to avoid GNU-C extensions.
1287 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1288 or failure rather than aborting on failure.
1290 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1292 (bfd_som_attach_aux_hdr): Add prototype.
1293 (hppa_som-gen_reloc_type): Likewise.

1322 action in case where caller specified no argument relocation.
1323 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
1324 right in the original relocation and the stub's relocation.
1326 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
1327 unused symbols argument.
1329 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
1330 than asymbol * for original target symbol. All callers changed.
1331 Set reloc->sym_ptr_ptr appropriately.
1332 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
1333 (hppa_elf_look_for_stubs_in_section): No longer need symbols
1334 argument. Use the output symbols when canonicalizing the relocs,
1335 creating them if necessary.
1337 * linker.c (_bfd_generic_link_output_symbols): Do not
1338 rebuild/clobber the output symbols if they already exist.
1340 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
1342 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

1344 * bfd-in2.h: Rebuilt.
1346 * srec.c (hex_value): Always set to a size of 256 bytes.

1351 * elf32-hppa.c: Second half of major cleanup. More comments,
1352 PARAMize and staticize rest of functions. Delete unused
1353 functions. Delete unused/unnecessary arguments to some functions.
1354 Group static vars together. Abort for bad errors until we have
1355 error code propogation working. Work on spacing and indention.
1356 Add FIXMEs for unresolved problems. Use enums rather than
1357 #defines for lots of things. Merge two functions which build
1358 linker stubs into a single function (so they can easily share a
1359 ton of common code).

1585 (b_out_relax_section): If a section contains no relocations, don't
1586 bother processing them.
1587 (b_out_get_relocated_section_contents): Set reloc_done. Assert

1599 fixed some comments, removed some "#if 1" lines.

1671 Make all callers of malloc or realloc (including via obstacks)
1672 check the result for NULL. Most set bfd_error to no_memory and

3551 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3553 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
3554 Handle symbol number of zero.
3556 * reloc.c (enum bfd_reloc_code_real): Added
3557 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
3558 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
3559 * bfd-in2.h: Rebuilt.
3560 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
3561 BFD_RELOC_MIPS_LITERAL.
3562 * elf32-mips.c (mips_reloc_map): Handle new relocs.
3563 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
3566 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
3567 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
3568 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
3569 MY_bfd_seclet_link): Define.
3570 (MY_bfd_reloc_type_lookup): Rename from
3571 MY_reloc_howto_type_lookup.
3572 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
3573 (MY(vec)): Use JUMP_TABLE rather than listing functions.
3574 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
3575 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
3576 terms of MY, because that causes a recusive invocation of CAT when
3577 expanded within JUMP_TABLE, and ANSI compilers don't expand
3579 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
3580 MY_reloc_howto_type_lookup, and don't define in terms of MY.
3581 (MY_canonicalize_reloc): Don't define in terms of MY.
3582 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
3583 than listing functions.
3585 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
3587 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
