969 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
971 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
972 reloc, used in embedded PIC code.

978 relocs when allocating space for relocations. Set SEC_RELOC flag
979 for any section which has relocs. Handle link_order relocs in
980 link_order loop. Use _bfd_generic_link_add_symbols_collect for
981 add_symbls entry point.

1014 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1016 Support for link_order types which generate relocs in order to
1017 support -Ur in the linker.
1018 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1019 from call to _bfd_generic_link_add_one_symbol.
1020 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1021 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1022 instead of bitsize to add_to_set call back.
1023 (_bfd_generic_final_link): Account for link_order relocs when
1024 allocating space for relocations. Handle them in link_order loop.
1025 (_bfd_generic_reloc_link_order): New function.

1044 (ecoff_link_write_external): Set the storage class of a defined
1045 linker created symbol based on the section it is in. Correct
1046 bfd_link_hash_weak case to use .sc rather than .st.
1047 (ecoff_reloc_link_order): New function.
1048 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

1059 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1061 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).

1064 comparison for function symbols within executables.
1066 * som.c (bfd_section_from_som_symbol): Renamed from
1067 som_section_from_subspace_index. Pass in a native SOM symbol.
1068 For executables, iterate through the sections to find out
1069 which contains the symbol's address rather than using the
1070 symbol_info field. (symbol_info has a different meaning for
1071 dynamicly linked executables.)
1073 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1076 * som.c (som_begin_writing): Fix braino (one call to align
1077 space/subspace data was done unconditionally rather than
1078 just for executables.)
1080 * som.c (som_begin_writing): Align text in all executables to
1081 make HPUX kernel happy. Fixes strip/objcopy for shared
1084 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1086 * som.c (som_begin_writing): Account for alignment needs of
1087 subspaces too when writing executables. Never request a negative
1088 bss size. Fixes some problems with demand paged executables,
1089 still having problems with pure executables and shared executables.
1091 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1093 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1094 bfd_zalloc for rawptr, because later on we may call free, not
1097 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1098 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1099 * cisco-core.c: New file.
1100 * Makefile.in: Change accordingly.
1101 * configure.in: Recognize cisco_core_vec.
1102 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1103 * targets.c: Add cisco_core_vec.
1104 * bfd-in2.h: Rebuilt.
1106 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1108 * som.h (som_copyable_section_data_struct): New structure
1109 containing all the private section information which needs
1110 to be copied from input section to output section during
1112 (som_section_data_struct): Remove several fields now in
1113 som_copyable_section_data_struct. Make the space and
1114 subspace dictionaries be pointers (to save space when
1115 only reading objects).
1117 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1118 some references changed. Allocate a copyable data stucture if
1119 none exists. Store info into the copyable data structure.
1120 (bfd_som_set_subsection_attributes): Likewise.
1121 (som_is_space, som_is_subspace, som_is_container): New functions.
1122 Use these instead of directly accessing private data.
1123 (som_prep_headers): Allocate space and subspace headers here.
1124 Fill in some fields in the space/subspace headers from the
1126 (som_bfd_copy_private_section_data): Only copy the stuff
1127 that we really need to make objcopy and strip work. Allocate
1128 the copy_data structure for the output bfd before copying.
1130 * som.h (struct som_exec_data): New structure to hold exec
1131 info that must be preserved when running objcopy/strip.
1132 (struct somdata): Add new "exec_data" field and accessor
1133 macro. Add some comments on how the various fields are used.
1134 (som_section_data_struct): Make is_space and is_subspace bitfields.
1135 Delete unused subspace_index. All references now use the
1136 target_index field within the section structure itself.
1138 * som.c (make_unique_section): Delete unused declaration.
1139 (som_bfd_copy_private_bfd_data): New function.
1140 (som_object_setup): Allocate space for and save exec information
1141 that needs to be copied during objcopy/strip.
1142 (som_mkobject): Do not allocate space for a file header here.
1143 It is not used when only reading SOM objects.
1144 (som_prep_headers): Allocate space for and attach a file header
1145 to the output bfd. For executables, use the saved system_id
1146 value rather than trying to guess the right value. Do not abort
1147 wwhen setting file_hdr->entry* for executables.
1148 (som_begin_writing): For executables, set the exec_entry and
1150 (som_copy_private_backend_section_data): Always return a value.
1152 * libhppa.h (PA_PAGESIZE): Define.
1154 * som.c (SOM_ALIGN): Define.
1155 (som_begin_writing): If writing an executable, initialize all
1156 fields in the exec header to zero. Update fields in the exec
1157 header as sizes of loadable subspaces are computed. Carefully
1158 preserve alignments when building executables. Actually write the
1159 exec after all the fields are filled in.
1161 * Better long-filename handling. Reads SOM ABI compliant extended
1162 names, but doesn't quite write compliant extended names yet.
1163 * som.c (som_slurp_extended_name_table): Delete function. The
1164 generic code will handle things correctly.
1165 (som_slurp_armap): Seek to the beginning of the next member.
1166 (normalize): New function.
1167 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1168 name table into account when computing the file offsets in the
1169 SOM dictionary. Make sure to align to an even boundary.
1170 (som_write_armap): Initialize the checksum to zero.
1171 (ar_maxchars): Fix. Opps.
1173 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1175 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1176 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1178 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1180 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1181 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1182 * bfd-in2.h: Regenerated.
1184 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1185 this was also named trad_unix_bfd_copy_private_bfd_data.
1187 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1189 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1190 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1191 returns NULL, it is not an error. It's possible that some of
1192 these checks are not necessary (because the size can never be
1193 zero), but putting in the checks is the conservative thing to do
1194 in light of the fact that some of these malloc calls replaced
1195 unchecked alloca calls, in which a zero argument would work fine.
1197 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1199 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1200 duplicate definition.
1201 (osf_core_bfd_is_local_label): Define.
1203 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1204 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1205 failure indication, it merely means there are no relocs.
1207 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1208 after NAME, since SunOS /bin/cc can't handle it.
1210 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1212 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1213 From sukes@glue.umd.edu (Tasuki Hirata).
1215 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1217 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1218 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1219 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1221 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1223 * som.c (som_prep_for_fixups): Detect section symbols based
1224 on either the lack of private data or the symbol flags. Do not
1225 munge section symbol names anymore -- they no longer confuse GDB.
1226 (som_begin_writing): Leave space for an exec header if writing
1228 (som_slurp_symbol_table): Recognize both forms of section symbol
1229 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1230 section symbols to be the name of the section they represent.
1231 Debugging symbols begin with "L$0\001", not just "L$".
1233 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1235 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1237 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1238 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1239 and bfd_is_local_label.
1241 * targets.c: Add new entries to the bfd_target structure.
1243 * bfd.c (bfd_copy_private_bfd_data): New definition.
1245 * section.c (bfd_copy_private_section_data): New definition.
1247 * syms.c (bfd_is_local_label): New definition.
1249 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1251 * libbfd.c (bfd_generic_is_local_label): New function.
1253 * *-core.c: Provide default definitions for new functions in
1254 the target vector which all point to bfd_false.
1256 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1257 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1258 Default new vectors for copying private backend data to bfd_true.
1259 Default new vector for determining if a symbol is a local label
1260 to bfd_generic_is_local_label.
1262 * som.c (som_bfd_copy_private_section_data): New function.
1263 (som_bfd_is_local_label): New function.
1264 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1266 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1268 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1270 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1272 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1275 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1276 Indent some of them to GNU standards.
1278 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1279 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1280 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1281 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1282 Update copyright years.
1284 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1286 * som.c (som_prep_for_fixups): A relocation involving the section
1287 symbol for the *ABS* section is really a relocation involving
1289 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1290 undefined symbols. Correctly distinguish between debugger symbols
1291 and section symbols.
1293 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1294 for spaces and subspaces.
1296 * som.c (som_bfd_count_ar_symbols): Fix typo.
1298 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1299 HAS_RELOC based on the object's magic number.
1300 (make_unique_section): Delete function. BFD and its users are
1301 prepared to handle multiple sections with the same name.
1302 (setup_sections): Allocate space on the BFD's obstack to hold
1303 section names. Use bfd_make_setion_anyway rather than the
1304 obsolete make_unique_section.
1305 (som_prep_headers): Choose the correct SOM magic number based
1307 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1309 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1311 * elf32-ppc.c: Renamed from elf32-powerpc.c.
1312 start-sanitize-powerpc-netware
1313 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
1314 end-sanitize-powerpc-netware
1315 * Makefile.in, configure.in: Corresponding changes.

1319 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
1321 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1323 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1324 is always located at the start of the data section to allow
1325 recovery of the dynamic info from a stripped executable.
1326 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1329 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1331 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1332 cruft (like the #pragma alloca for AIX).
1333 In addition to that problem, the C alloca calls xmalloc, which
1334 means checking for being out of memory can't work right. The
1335 following changes remove all uses of alloca from BFD.
1336 * hosts/solaris2.h: Remove alloca cruft.
1337 * som.c: Replace alloca with a fixed size auto array.

1689 bother processing them.
1690 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2393 The sparc (and possibly other?) NLM format requires a different
2394 way to write exports, so add a write_export field to the backend
2395 data (and set it to NULL for everything but the sparc).

2561 sym_filepos as well.
2562 (ecoff_get_extr): Use ifdmap instead of ifdbase.

2634 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

2639 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
2640 different, so there is no point to providing a generic one.
2641 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
2642 in the backend accessor macros; that should no longer be possible.
