894 required by expansions. Set s and unset h when converting a reloc
895 from undefined to section. Change handling of PC relative relocs:
896 if against a section, they are correct in the object file, if
897 against an external symbol they are pcrel_offset.

1027 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1029 Support for link_order types which generate relocs in order to
1030 support -Ur in the linker.
1031 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1032 from call to _bfd_generic_link_add_one_symbol.
1033 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1034 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1035 instead of bitsize to add_to_set call back.
1036 (_bfd_generic_final_link): Account for link_order relocs when
1037 allocating space for relocations. Handle them in link_order loop.
1038 (_bfd_generic_reloc_link_order): New function.

1057 (ecoff_link_write_external): Set the storage class of a defined
1058 linker created symbol based on the section it is in. Correct
1059 bfd_link_hash_weak case to use .sc rather than .st.

1077 comparison for function symbols within executables.
1079 * som.c (bfd_section_from_som_symbol): Renamed from
1080 som_section_from_subspace_index. Pass in a native SOM symbol.
1081 For executables, iterate through the sections to find out
1082 which contains the symbol's address rather than using the
1083 symbol_info field. (symbol_info has a different meaning for
1084 dynamicly linked executables.)
1086 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1089 * som.c (som_begin_writing): Fix braino (one call to align
1090 space/subspace data was done unconditionally rather than
1091 just for executables.)
1093 * som.c (som_begin_writing): Align text in all executables to
1094 make HPUX kernel happy. Fixes strip/objcopy for shared
1097 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1099 * som.c (som_begin_writing): Account for alignment needs of
1100 subspaces too when writing executables. Never request a negative
1101 bss size. Fixes some problems with demand paged executables,
1102 still having problems with pure executables and shared executables.
1104 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1106 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1107 bfd_zalloc for rawptr, because later on we may call free, not
1110 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1111 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1112 * cisco-core.c: New file.

1119 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1121 * som.h (som_copyable_section_data_struct): New structure
1122 containing all the private section information which needs
1123 to be copied from input section to output section during
1125 (som_section_data_struct): Remove several fields now in
1126 som_copyable_section_data_struct. Make the space and
1127 subspace dictionaries be pointers (to save space when
1128 only reading objects).
1130 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1131 some references changed. Allocate a copyable data stucture if
1132 none exists. Store info into the copyable data structure.
1133 (bfd_som_set_subsection_attributes): Likewise.
1134 (som_is_space, som_is_subspace, som_is_container): New functions.
1135 Use these instead of directly accessing private data.
1136 (som_prep_headers): Allocate space and subspace headers here.
1137 Fill in some fields in the space/subspace headers from the
1139 (som_bfd_copy_private_section_data): Only copy the stuff
1140 that we really need to make objcopy and strip work. Allocate
1141 the copy_data structure for the output bfd before copying.
1143 * som.h (struct som_exec_data): New structure to hold exec
1144 info that must be preserved when running objcopy/strip.
1145 (struct somdata): Add new "exec_data" field and accessor
1146 macro. Add some comments on how the various fields are used.
1147 (som_section_data_struct): Make is_space and is_subspace bitfields.
1148 Delete unused subspace_index. All references now use the
1149 target_index field within the section structure itself.
1151 * som.c (make_unique_section): Delete unused declaration.
1152 (som_bfd_copy_private_bfd_data): New function.
1153 (som_object_setup): Allocate space for and save exec information
1154 that needs to be copied during objcopy/strip.
1155 (som_mkobject): Do not allocate space for a file header here.
1156 It is not used when only reading SOM objects.
1157 (som_prep_headers): Allocate space for and attach a file header
1158 to the output bfd. For executables, use the saved system_id
1159 value rather than trying to guess the right value. Do not abort
1160 wwhen setting file_hdr->entry* for executables.
1161 (som_begin_writing): For executables, set the exec_entry and
1163 (som_copy_private_backend_section_data): Always return a value.
1165 * libhppa.h (PA_PAGESIZE): Define.
1167 * som.c (SOM_ALIGN): Define.
1168 (som_begin_writing): If writing an executable, initialize all
1169 fields in the exec header to zero. Update fields in the exec
1170 header as sizes of loadable subspaces are computed. Carefully
1171 preserve alignments when building executables. Actually write the
1172 exec after all the fields are filled in.
1174 * Better long-filename handling. Reads SOM ABI compliant extended
1175 names, but doesn't quite write compliant extended names yet.
1176 * som.c (som_slurp_extended_name_table): Delete function. The
1177 generic code will handle things correctly.
1178 (som_slurp_armap): Seek to the beginning of the next member.
1179 (normalize): New function.
1180 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1181 name table into account when computing the file offsets in the
1182 SOM dictionary. Make sure to align to an even boundary.
1183 (som_write_armap): Initialize the checksum to zero.
1184 (ar_maxchars): Fix. Opps.

1188 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1189 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1191 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1193 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1194 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1195 * bfd-in2.h: Regenerated.
1197 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1198 this was also named trad_unix_bfd_copy_private_bfd_data.
1200 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1202 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1203 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1204 returns NULL, it is not an error. It's possible that some of
1205 these checks are not necessary (because the size can never be
1206 zero), but putting in the checks is the conservative thing to do
1207 in light of the fact that some of these malloc calls replaced
1208 unchecked alloca calls, in which a zero argument would work fine.
1210 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1212 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1213 duplicate definition.
1214 (osf_core_bfd_is_local_label): Define.
1216 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1217 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1218 failure indication, it merely means there are no relocs.
1220 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1221 after NAME, since SunOS /bin/cc can't handle it.
1223 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1225 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1226 From sukes@glue.umd.edu (Tasuki Hirata).
1228 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1230 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1231 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1232 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1234 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1236 * som.c (som_prep_for_fixups): Detect section symbols based
1237 on either the lack of private data or the symbol flags. Do not
1238 munge section symbol names anymore -- they no longer confuse GDB.
1239 (som_begin_writing): Leave space for an exec header if writing
1241 (som_slurp_symbol_table): Recognize both forms of section symbol
1242 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1243 section symbols to be the name of the section they represent.
1244 Debugging symbols begin with "L$0\001", not just "L$".
1246 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1248 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1250 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1251 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1252 and bfd_is_local_label.

1270 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1271 Default new vectors for copying private backend data to bfd_true.
1272 Default new vector for determining if a symbol is a local label
1273 to bfd_generic_is_local_label.
1275 * som.c (som_bfd_copy_private_section_data): New function.
1276 (som_bfd_is_local_label): New function.
1277 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1279 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1281 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1283 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1285 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1288 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1289 Indent some of them to GNU standards.
1291 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1292 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

1294 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1295 Update copyright years.
1297 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1299 * som.c (som_prep_for_fixups): A relocation involving the section
1300 symbol for the *ABS* section is really a relocation involving
1302 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1303 undefined symbols. Correctly distinguish between debugger symbols
1304 and section symbols.
1306 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1307 for spaces and subspaces.
1309 * som.c (som_bfd_count_ar_symbols): Fix typo.
1311 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1312 HAS_RELOC based on the object's magic number.
1313 (make_unique_section): Delete function. BFD and its users are
1314 prepared to handle multiple sections with the same name.
1315 (setup_sections): Allocate space on the BFD's obstack to hold
1316 section names. Use bfd_make_setion_anyway rather than the
1317 obsolete make_unique_section.
1318 (som_prep_headers): Choose the correct SOM magic number based
1320 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

1336 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1337 is always located at the start of the data section to allow
1338 recovery of the dynamic info from a stripped executable.
1339 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1342 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1344 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1345 cruft (like the #pragma alloca for AIX).
1346 In addition to that problem, the C alloca calls xmalloc, which
1347 means checking for being out of memory can't work right. The
1348 following changes remove all uses of alloca from BFD.
1349 * hosts/solaris2.h: Remove alloca cruft.
1350 * som.c: Replace alloca with a fixed size auto array.

1701 (b_out_relax_section): If a section contains no relocations, don't
1702 bother processing them.
1703 (b_out_get_relocated_section_contents): Set reloc_done. Assert

1787 Make all callers of malloc or realloc (including via obstacks)
1788 check the result for NULL. Most set bfd_error to no_memory and
1789 return in that case; a few are harder to fix, and are marked

2406 The sparc (and possibly other?) NLM format requires a different
2407 way to write exports, so add a write_export field to the backend
2408 data (and set it to NULL for everything but the sparc).

2574 sym_filepos as well.
2575 (ecoff_get_extr): Use ifdmap instead of ifdbase.

2647 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

2650 * configure.in (nlm32_alpha_vec): Set target64 to true.
2652 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
2653 different, so there is no point to providing a generic one.
2654 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
2655 in the backend accessor macros; that should no longer be possible.
2656 * targets.c (target_vector): Removed nlm32_big_generic_vec,
