+ * Makefile.in (INSN_ATTR_H): New macro. Replace all dependencies
+ on insn-attr.h with it.
+ * genattr.c: Generate `#include "insn-addr.h"' if HAVE_ATTR_length.
+ * insn-addr.h: New header.
+ (insn_addresses_): Renamed from insn_addresses.
+ (INSN_ADDRESSES_DEFN, INSN_ADDRESSES, INSN_ADDRESSES_ALLOC,
