efriedma added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/SROA.cpp:1709
+      return OldAS == NewAS ||
+             DL.getPointerSize(OldAS) == DL.getPointerSize(NewAS);
     }
----------------
Do you need to check isNonIntegralPointerType()?


================
Comment at: llvm/lib/Transforms/Scalar/SROA.cpp:1782
+    // checked convertible, i.e. they have the same pointer size), use a pair
+    // of no-op `ptrtoint`/`inttoptr` casts through an integer.
+    if (OldAS != NewAS) {
----------------
Probably this comment should be clarified to explain why this isn't an addrspacecast.
