812 input BFDs.
813 (aout_link_reloc_link_order): New function.
814 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
815 call to _bfd_generic_link_add_one_symbol.
816 (ecoff_bfd_final_link): Account for link_order relocs when
817 allocating space for relocations. Handle them in link_order loop.
818 (ecoff_link_write_external): Set the storage class of a defined
819 linker created symbol based on the section it is in. Correct
820 bfd_link_hash_weak case to use .sc rather than .st.
821 (ecoff_reloc_link_order): New function.
822 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
823 BFD_RELOC_CTOR.
824 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
825
826 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
827 and buf.
828
829 * cisco-core.c (cisco_core_file_p): Only pass one argument to
830 bfd_zmalloc. Free a pointer, not a union.
831 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
832
833 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
834
835 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
836
837 * som.c (bfd_section_from_som_symbol): Only to do the value
838 comparison for function symbols within executables.
839
840 * som.c (bfd_section_from_som_symbol): Renamed from
841 som_section_from_subspace_index. Pass in a native SOM symbol.
842 For executables, iterate through the sections to find out
843 which contains the symbol's address rather than using the
844 symbol_info field. (symbol_info has a different meaning for
845 dynamicly linked executables.)
846
847 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
848 bfd_zmalloc.
849
850 * som.c (som_begin_writing): Fix braino (one call to align
851 space/subspace data was done unconditionally rather than
852 just for executables.)
853
854 * som.c (som_begin_writing): Align text in all executables to
855 make HPUX kernel happy. Fixes strip/objcopy for shared
856 executables.
857
858 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
859
860 * som.c (som_begin_writing): Account for alignment needs of
861 subspaces too when writing executables. Never request a negative
862 bss size. Fixes some problems with demand paged executables,
863 still having problems with pure executables and shared executables.
864
865 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
866
867 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
868 bfd_zalloc for rawptr, because later on we may call free, not
869 bfd_release, on it.
870
871 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
872 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
873 * cisco-core.c: New file.
874 * Makefile.in: Change accordingly.
875 * configure.in: Recognize cisco_core_vec.
876 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
877 * targets.c: Add cisco_core_vec.
878 * bfd-in2.h: Rebuilt.
879
880 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
881
882 * som.h (som_copyable_section_data_struct): New structure
883 containing all the private section information which needs
884 to be copied from input section to output section during
885 objcopy or strip.
886 (som_section_data_struct): Remove several fields now in
887 som_copyable_section_data_struct. Make the space and
888 subspace dictionaries be pointers (to save space when
889 only reading objects).
890
891 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
892 some references changed. Allocate a copyable data stucture if
893 none exists. Store info into the copyable data structure.
894 (bfd_som_set_subsection_attributes): Likewise.
895 (som_is_space, som_is_subspace, som_is_container): New functions.
896 Use these instead of directly accessing private data.
897 (som_prep_headers): Allocate space and subspace headers here.
898 Fill in some fields in the space/subspace headers from the
899 copyable data.
900 (som_bfd_copy_private_section_data): Only copy the stuff
901 that we really need to make objcopy and strip work. Allocate
902 the copy_data structure for the output bfd before copying.
903
904 * som.h (struct som_exec_data): New structure to hold exec
905 info that must be preserved when running objcopy/strip.
906 (struct somdata): Add new "exec_data" field and accessor
907 macro. Add some comments on how the various fields are used.
908 (som_section_data_struct): Make is_space and is_subspace bitfields.
909 Delete unused subspace_index. All references now use the
910 target_index field within the section structure itself.
911
912 * som.c (make_unique_section): Delete unused declaration.
913 (som_bfd_copy_private_bfd_data): New function.
914 (som_object_setup): Allocate space for and save exec information
915 that needs to be copied during objcopy/strip.
916 (som_mkobject): Do not allocate space for a file header here.
917 It is not used when only reading SOM objects.
918 (som_prep_headers): Allocate space for and attach a file header
919 to the output bfd. For executables, use the saved system_id
920 value rather than trying to guess the right value. Do not abort
921 wwhen setting file_hdr->entry* for executables.
922 (som_begin_writing): For executables, set the exec_entry and
923 exec_flags fields.
924 (som_copy_private_backend_section_data): Always return a value.
925
926 * libhppa.h (PA_PAGESIZE): Define.
927
928 * som.c (SOM_ALIGN): Define.
929 (som_begin_writing): If writing an executable, initialize all
930 fields in the exec header to zero. Update fields in the exec
931 header as sizes of loadable subspaces are computed. Carefully
932 preserve alignments when building executables. Actually write the
933 exec after all the fields are filled in.
934
935 * Better long-filename handling. Reads SOM ABI compliant extended
936 names, but doesn't quite write compliant extended names yet.
937 * som.c (som_slurp_extended_name_table): Delete function. The
938 generic code will handle things correctly.
939 (som_slurp_armap): Seek to the beginning of the next member.
940 (normalize): New function.
941 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
942 name table into account when computing the file offsets in the
943 SOM dictionary. Make sure to align to an even boundary.
944 (som_write_armap): Initialize the checksum to zero.
945 (ar_maxchars): Fix. Opps.
946
947 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
948
949 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
950 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
951
952 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
953
954 * bfd-in.h (BFD_VERSION): Use @VERSION@.
955 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
956 * bfd-in2.h: Regenerated.
957
958 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
959 this was also named trad_unix_bfd_copy_private_bfd_data.
960
961 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
962
963 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
964 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
965 returns NULL, it is not an error. It's possible that some of
966 these checks are not necessary (because the size can never be
967 zero), but putting in the checks is the conservative thing to do
968 in light of the fact that some of these malloc calls replaced
969 unchecked alloca calls, in which a zero argument would work fine.
970
971 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
972
973 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
974 duplicate definition.
975 (osf_core_bfd_is_local_label): Define.
976
977 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
978 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
979 failure indication, it merely means there are no relocs.
980
981 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
982 after NAME, since SunOS /bin/cc can't handle it.
983
984 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
985
986 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
987 From sukes@glue.umd.edu (Tasuki Hirata).
988
989 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
990
991 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
992 all that convoluted stuff with NAME, CAT3, etc. The convoluted
993 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
994
995 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
996
997 * som.c (som_prep_for_fixups): Detect section symbols based
998 on either the lack of private data or the symbol flags. Do not
999 munge section symbol names anymore -- they no longer confuse GDB.
1000 (som_begin_writing): Leave space for an exec header if writing
1001 an executable.
1002 (som_slurp_symbol_table): Recognize both forms of section symbol
1003 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1004 section symbols to be the name of the section they represent.
1005 Debugging symbols begin with "L$0\001", not just "L$".
1006
1007 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1008
1009 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1010
1011 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1012 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1013 and bfd_is_local_label.
1014
1015 * targets.c: Add new entries to the bfd_target structure.
1016
1017 * bfd.c (bfd_copy_private_bfd_data): New definition.
1018
1019 * section.c (bfd_copy_private_section_data): New definition.
1020
1021 * syms.c (bfd_is_local_label): New definition.
1022
1023 * libbfd-in.h (bfd_generic_is_local_label): Declare.
1024
1025 * libbfd.c (bfd_generic_is_local_label): New function.
1026
1027 * *-core.c: Provide default definitions for new functions in
1028 the target vector which all point to bfd_false.
1029
1030 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1031 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1032 Default new vectors for copying private backend data to bfd_true.
1033 Default new vector for determining if a symbol is a local label
1034 to bfd_generic_is_local_label.
1035
1036 * som.c (som_bfd_copy_private_section_data): New function.
1037 (som_bfd_is_local_label): New function.
1038 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1039
1040 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1041
1042 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1043
1044 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1045
1046 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1047
1048 * Most files:
1049 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1050 Indent some of them to GNU standards.
1051
1052 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1053 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1054 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1055 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1056 Update copyright years.
1057
1058 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1059
1060 * som.c (som_prep_for_fixups): A relocation involving the section
1061 symbol for the *ABS* section is really a relocation involving
1062 no symbol.
1063 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1064 undefined symbols. Correctly distinguish between debugger symbols
1065 and section symbols.
1066
1067 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1068 for spaces and subspaces.
1069
1070 * som.c (som_bfd_count_ar_symbols): Fix typo.
1071
1072 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1073 HAS_RELOC based on the object's magic number.
1074 (make_unique_section): Delete function. BFD and its users are
1075 prepared to handle multiple sections with the same name.
1076 (setup_sections): Allocate space on the BFD's obstack to hold
1077 section names. Use bfd_make_setion_anyway rather than the
1078 obsolete make_unique_section.
1079 (som_prep_headers): Choose the correct SOM magic number based
1080 on the BFD's flags.
1081 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1082
1083 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1084
1085 * elf32-ppc.c: Renamed from elf32-powerpc.c.
1086 start-sanitize-powerpc-netware
1087 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
1088 end-sanitize-powerpc-netware
1089 * Makefile.in, configure.in: Corresponding changes.
1090
1091 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

1094
1095 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1096
1097 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1098 is always located at the start of the data section to allow
1099 recovery of the dynamic info from a stripped executable.
1100 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1101 and STYP_COMMENT.
1102
1103 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1104
1105 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1106 cruft (like the #pragma alloca for AIX).
1107 In addition to that problem, the C alloca calls xmalloc, which
1108 means checking for being out of memory can't work right. The
1109 following changes remove all uses of alloca from BFD.
1110 * hosts/solaris2.h: Remove alloca cruft.
1111 * som.c: Replace alloca with a fixed size auto array.
1112 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
1113 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
1114 sunos.c: Replace alloca with malloc and appropriate error checking and
1115 freeing.
1116 * linker.c: Replace alloca with obstack_alloc.
1117 * libbfd.h: Rebuilt.
1118
1119 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1120
1121 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1122 MIPS_R_GPREL.
1123
1124 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1125
1126 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1127 Elf*_Off typedefs by their expansion, the typedefs have been
1128 removed from include/elf/internal.h.
1129 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1130 SHT_PROGBITS section.
1131
1132 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1133
1134 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
1135
1136 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1137
1138 * configure.host: Recognize i[34]86-sequent-*.
1139
1140 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1141 return from bfd_seek indicates an error.
1142 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1143 TRAD_CORE_STACK_OFFSET.
1144 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1145 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1146
1147 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1148
1149 * som.[ch]: Do not include libhppa.h in som.c, instead include
1150 it in som.h.
1151
1152 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1153 include it in elf32-hppa.h.
1154
1155 * som.c (log2): Return -1 on error rather than aborting.
1156 (setup_sections): Bubble up an error from log2.
1157
1158 * Changes to make HP C compiler happy in both traditional
1159 and ANSI mode.
1160 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1161 field parameter.
1162 (bfd_som_set_section_attributes): Use unsigned int rather than
1163 unsigned char to avoid GNU-C extensions.
1164 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1165 or failure rather than aborting on failure.
1166
1167 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1168 som.c changes.
1169 (bfd_som_attach_aux_hdr): Add prototype.
1170 (hppa_som-gen_reloc_type): Likewise.
1171
1172 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
1173 (hppa_look_for_stubs_in_section): Do not return false on failure
1174 until rest of code is ready to handle it. Abort for now.
1175
1176 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1177
1178 * bfd-in2.h: Rebuilt.
1179
1180 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
1181
1182 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
1183 * Makefile.in: delete an extra blank.
1184 * configure.in : Add i396os9k_vec.
1185
1186 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
1187
1188 * config.bfd : Add i386-os9k.
1189 * config/i386-os9k.mt : Newly add os9k target makefile.
1190
1191 * i386os9k.c : new file to handle os9k format bfd.
1192 * Makefile.in : Handle new file i386os9k.c
1193 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
1194 * cache.c : Initialize cache_sentinel to 0.
1195
1196 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1197
1198 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
1199 action in case where caller specified no argument relocation.
1200 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
1201 right in the original relocation and the stub's relocation.
1202
1203 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
1204 unused symbols argument.
1205
1206 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
1207 than asymbol * for original target symbol. All callers changed.
1208 Set reloc->sym_ptr_ptr appropriately.
1209 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
1210 (hppa_elf_look_for_stubs_in_section): No longer need symbols
1211 argument. Use the output symbols when canonicalizing the relocs,
1212 creating them if necessary.
1213
1214 * linker.c (_bfd_generic_link_output_symbols): Do not
1215 rebuild/clobber the output symbols if they already exist.
1216
1217 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
1218
1219 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
1220 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
1221 * bfd-in2.h: Rebuilt.

1227
1228 * elf32-hppa.c: Second half of major cleanup. More comments,
1229 PARAMize and staticize rest of functions. Delete unused
1230 functions. Delete unused/unnecessary arguments to some functions.
1231 Group static vars together. Abort for bad errors until we have
1232 error code propogation working. Work on spacing and indention.
1233 Add FIXMEs for unresolved problems. Use enums rather than
1234 #defines for lots of things. Merge two functions which build
1235 linker stubs into a single function (so they can easily share a
1236 ton of common code).
1237

1239

1279 static vars together. Collapse common case statements together
1280 in many places. Use default case when possible instead of listing
1281 each case separately. Abort for bad errors until we get error
1282 code propogation working. Work on spacing and indention problems.
1283 Add FIXMEs for some unresolved problems. Delete hopelessly broken
1284 COMPLEX relocation support (it's never used anyway).
1285 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

1329
1330 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

1448
1449 * section.c (bfd_get_section_contents): Since this function reads
1450 unrelocated contents, the section's raw size is always the one to
1451 use for bounds checking.

1469 raw size of the input section.
1470
1471 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
1472 bout. Default with no version number is still bout. Support
1473 explicit i960-coff target too.

1548 Make all callers of malloc or realloc (including via obstacks)
1549 check the result for NULL. Most set bfd_error to no_memory and

2027
2028 * som.c, som.h (bfd_som_set_section_attributes,
2029 bfd_som_set_subsection_attributes): Change parameters from char
2030 to int. Following a prototype with an old-style function definition
2031 in the presence of widened parameters is a GCC-ism not supported
2032 by the HP compiler in ANSI mode.

2041
2042 * archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
2043 try to overlay the internal carsyms on the external symdefs. That

2115 get the index of a common section, rather than always using
2116 SHN_COMMON (MIPS has multiple common sections).
2117
2118 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).

2140 undefined, look it up in the linker hash table.
2141
2142 * aoutx.h (translate_symbol_table): The string index 0 has a
2143 special meaning for normal symbols, but not for dynamic symbols.

2213 return value.
2214 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
2215 out dynamic symbols or relocs against reloc symbols, since they
2216 are already in the .text section and we wouldn't know where to
2217 write them anyhow.
2218 (sunos4_aout_backend): Initialize read_dynamic_symbols and
2219 read_dynamic_relocs fields.
2220 * aout-target.h (MY(backend_data)): Initialize

2224
2225 * hosts/alphaosf.h (uint64e_type, uint64_type, int64_type): Delete

2277 the DYNAMIC flag for the BFD.
2278 (NAME(bfd_elf,write_object_contents)): Don't try to write out a
2279 BFD with the DYNAMIC flag set, since we don't generate the program
2280 header table correctly.
2281

2329
2330 * ecofflink.c: Extensive changes to compress and merge debugging

2401
2402 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
2403 count it as a wrong format error, not a system call error, since
2404 the object file might simply be too small.
2405
2406 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
2407 BFD64.
2408 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.
2409 (BFD64_BACKENDS): Add nlm32-alpha.o. It depends on 64 bit
2410 support, even though it is for an Alpha in 32 bit mode.
2411 * configure.in (nlm32_alpha_vec): Set target64 to true.
2412
2413 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are

2415 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
2416 in the backend accessor macros; that should no longer be possible.
