813 rather than asymbol list. Only return false if an error occurred.
814 Set *again to false. Get symbols from BFD.
815 * coffcode.h (bfd_coff_backend_data): Change
816 _bfd_coff_reloc16_estimate to take BFD argument rather than
817 asymbol list.

842 in asymbol udata field.
843

850 MIPS_R_PCREL16.
851
852 * elf32-mips.c (mips_elf_final_link): Account for link_order
853 relocs when allocating space for relocations. Set SEC_RELOC flag
854 for any section which has relocs. Handle link_order relocs in
855 link_order loop. Use _bfd_generic_link_add_symbols_collect for
856 add_symbls entry point.
857
858 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
859 counting relocs. Set SEC_RELOC flag for any section which has
860 relocs.

863
864 * linker.c (_bfd_generic_link_add_symbols): Just call
865 generic_link_add_symbols.
866 (_bfd_generic_link_add_symbols_collect): New function, like
867 _bfd_generic_link_add_symbols but also collect constructors and
868 destructors by name as collect2 does.
869 (generic_link_add_symbols): New function, like old
870 _bfd_generic_link_add_symbols but with collect argument.
871 (generic_link_add_object_symbols): Take collect argument.
872 (generic_link_check_archive_element_no_collect): New function.

880
881 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
882
883 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
884 for first character in an extended name.
885 (_bfd_write_archive_contents): If ar_padchar == '/', then use
886 "//" as the name of the special archive member holding the
887 extended name table.
888
889 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
890
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,
902 abort.
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.
908 * libbfd.h: Rebuilt.
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

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

928 and buf.
929
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.
933
934 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
935
936 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
937
938 * som.c (bfd_section_from_som_symbol): Only to do the value
939 comparison for function symbols within executables.
940
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.)
947
948 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
949 bfd_zmalloc.
950
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.)
954
955 * som.c (som_begin_writing): Align text in all executables to
956 make HPUX kernel happy. Fixes strip/objcopy for shared
957 executables.
958
959 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
960
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.
965
966 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
967
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
970 bfd_release, on it.
971
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.
980
981 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
982
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
986 objcopy or strip.
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).
991
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
1000 copyable data.
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.
1004
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.
1012
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
1024 exec_flags fields.
1025 (som_copy_private_backend_section_data): Always return a value.
1026
1027 * libhppa.h (PA_PAGESIZE): Define.
1028
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.
1035
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.
1047
1048 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1049
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.
1052
1053 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1054
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.
1058
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.
1061
1062 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1063
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.
1071
1072 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1073
1074 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1075 duplicate definition.
1076 (osf_core_bfd_is_local_label): Define.
1077
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.
1081
1082 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1083 after NAME, since SunOS /bin/cc can't handle it.
1084
1085 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1086
1087 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1088 From sukes@glue.umd.edu (Tasuki Hirata).
1089
1090 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1091
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).
1095
1096 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1097
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
1102 an executable.
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$0\001", not just "L$".
1107
1108 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1109
1110 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1111
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.
1115
1116 * targets.c: Add new entries to the bfd_target structure.
1117
1118 * bfd.c (bfd_copy_private_bfd_data): New definition.

1120 * section.c (bfd_copy_private_section_data): New definition.
1121
1122 * syms.c (bfd_is_local_label): New definition.
1123
1124 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1125
1126 * libbfd.c (bfd_generic_is_local_label): New function.
1127
1128 * *-core.c: Provide default definitions for new functions in
1129 the target vector which all point to bfd_false.
1130
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.
1136
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.
1140
1141 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1142
1143 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1144
1145 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1146
1147 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1148
1149 * Most files:
1150 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1151 Indent some of them to GNU standards.
1152
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.
1158
1159 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1160
1161 * som.c (som_prep_for_fixups): A relocation involving the section
1162 symbol for the *ABS* section is really a relocation involving
1163 no symbol.
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.
1167
1168 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1169 for spaces and subspaces.
1170
1171 * som.c (som_bfd_count_ar_symbols): Fix typo.
1172
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
1181 on the BFD's flags.
1182 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1183
1184 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1185
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.
1191
1192 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1193
1194 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
1195
1196 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1197
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
1202 and STYP_COMMENT.
1203
1204 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1205
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
1216 freeing.
1217 * linker.c: Replace alloca with obstack_alloc.
1218 * libbfd.h: Rebuilt.
1219
1220 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1221
1222 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like

2508 BFD64.
2509 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

2512 * configure.in (nlm32_alpha_vec): Set target64 to true.
2513
2514 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
