You're thinking of L^, W^, B^ and S^ for qualifying the type of an
operand.  So you could see

   movl #L^^X12, r0
   movl #W^^X12, r0
   movl #B^^X12, r0
   movl #S^^X12, r0

These all do the same think, but the first argument gets encoded
differently each time (top-to-bottom is longest-to-shortest).
