+ * elf32-arc.c (arc_bfd_get_32): Becomes an alias for bfd_get_32.
+ (arc_bfd_put_32): Becomes an alias for bfd_put_32.
+ (arc_elf_howto_init): Added assert to validate relocations.
+ (get_middle_endian_relocation): Delete.
+ (middle_endian_convert): New function.
+ (ME): Redefine, now does nothing.
+ (IS_ME): New define.
+ (arc_do_relocation): Extend the attached 'ARC_RELOC_HOWTO'
+ definition to call middle_endian_convert. Add a new local
+ variable and make use of this throughout. Added call to
+ arc_bfd_get_8 and arc_bfd_put_8 for 8 bit relocations.
