How to handle ISD::STORE when both operands are FrameIndex?

return cast<MemSDNode>(N)->getAddressSpace() == 1;
}]>;
class StoreFrag<SDPatternOperator op> : PatFrag <

def store_stack : StackStore<store>;
def StoreStackF : InstRI<2, (outs), (ins IntRegs:$reg, i32imm:$i),
"storestackf $reg, [$i]", [(store_stack i32:$reg,
AddrFI:$i)]>;
I'm puzzled why...
