I may have listed more operations than necessary, but the important bit is that you need to form arbitrary addresses in the stack frame without touching flags. If for any const_int N, (plus reg N) is a valid address for moves to and from memory that doesn't touch flags, then I suppose you don't *need* an "add" that doesn't touch flags. brgds, H-P
