+  if (STI.useR7AsFramePointer())
+    PopFriendly.set(ARM::R7);
If you want exactly the set r0...r7, shouldn't you just set that, rather than getting the set of allocatable registers and adding back specific registers?  That would simplify the code a bit because findTemporariesForLR would be guaranteed to succeed.
