I'm looking into it right now.  I'm not sure about one thing: should "movmemhi" 
handle only constant block sizes, or variable block sizes too?  If variable - 
is it safe to assume nonzero?  (now 0 means 65536) 
 
Operand 2 (block size) has the "const_int_operand" predicate - doesn't this 
mean that (GET_CODE(operands[2]) == CONST_INT) is always true? 
 
Thanks, 
Marek
