3 * nlmcode.h, liblnm.h, nlm32-alpha.c nlm32-i386.c nlm32-sparc.c:
4 The sparc (and possibly other?) NLM format requires a different
5 way to write exports, so add a write_export field to the backend
6 data (and set it to NULL for everything but the sparc).

1142 * elfcode.h (elf_object_p): Rather than looking through an array
1143 of architectures, get the ELF EM_xxx code from the backend
1144 information. Let the generic ELF target match any EM_xxx code not
1145 matched by another ELF target. Call elf_backend_object_p to let
1146 the backend do more checks and set global information.
1147 * libelf.h (struct elf_backend_data): Added elf_machine_code and
1148 elf_backend_object_p fields.
1149 (struct bfd_elf_arch_map): Removed.
1150 (bfd_elf_arch_map, bfd_elf_arch_map_size): Don't declare.
1151 * elf32-target.h, elf64-target.h: Initialize elf_machine_code
1152 field with ELF_MACHINE_CODE. Initialize elf_backend_object_p
1153 field with elf_backend_object_p (if it is defined).
1154 * elf32-gen.c, elf32-hppa.c, elf32-i386.c, elf32-i860.c,
1155 elf32-m68k.c, elf32-m88k.c, elf32-mips.c, elf32-sparc.c,
1156 elf64-gen.c (ELF_MACHINE_CODE): Defined.
1157 * elf32-mips.c: Include ecoffswap.h to get ECOFF swapping
1158 routines.
1159 (mips_elf_object_p): Set the right machine number.
1160 (mips_elf_ecoff_debug_swap): Defined.
1161 (elf_backend_object_p): Defined to be mips_elf_object_p.
1162 (elf_backend_ecoff_debug_swap): Defined to be
1163 mips_elf_ecoff_debug_swap.
1164 * elf.c (bfd_elf_arch_map, bfd_elf_arch_map_size): Removed.
1165
1166 * libbfd-in.h (target_vector, default_vector): Declare.
1167 * libbfd.h: Rebuilt.
1168 * format.c (target_vector, default_vector): Don't declare.
1169
1170 * elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
1171 for R_MIPS_26. Correct overflow detection requires matching the
1172 upper four bits of the destination against the PC. From Ted Lemon
1173 <mellon@pepper.ncd.com>.
1174
1175 * bout.c (b_out_reloc_type_lookup): Return type should point to
1176 const data.
1177 * coff-i960.c (coff_i960_reloc_type_lookup): Likewise.
1178 * elf32-hppa.c (elf_hppa_reloc_type_lookup): Likewise.
1179 * mipsbsd.c (MY(reloc_howto_type_lookup)): Likewise.
1180 * coff-i386.c (coff_i386_reloc): Made howto const.
1181 * oasys.c (oasys_write_data): Made how const.
1182

ILT
1183 * libelf.h: Added some comments.
1184 (struct elf_backend_data): Added elf_backend_ecoff_debug_swap
1185 field. Removed unused write_relocs field.
1186 * elf32-target.h: Adjusted elf_backend_data initialization
1187 accordingly.
1188 * elf64-target.h: Corrected elf_backend_data initialization to
1189 fill in all fields and to set elf_64_p to 1.
