================
Comment at: clang/lib/Sema/SemaExpr.cpp:486
     if (UO->getOpcode() == UO_Deref &&
-        UO->getSubExpr()->IgnoreParenCasts()->
-          isNullPointerConstant(S.Context, Expr::NPC_ValueDependentIsNotNull) &&
+        !isTargetAddressSpace(
+            UO->getSubExpr()->getType()->getPointeeType().getAddressSpace()) &&
----------------
With this patch, we no longer warn for:

*(int __attribute__((address_space(0))) *) 0;

Worth to handle this case?
