+ else if (N->getNumOperands() && isa<GlobalAddressSDNode>(BasePtr->getOperand(0)))
+ NumRegs = 3;
+ for (unsigned i = 3, e = N->getNumOperands(); i != e; ++i)
----------------
Why do we need to check `N->getNumOperands()`?

+ NumRegs = 3;
+ for (unsigned i = 3, e = N->getNumOperands(); i != e; ++i)
+ if (isa<RegisterSDNode>(N->getOperand(i)) && ( NumRegs-- == 0))
----------------
Should we add 2 more tests for the 2 `NumRegs = 3`?
