[PATCH] D142584: [CodeGen] Add a boolean flag to `Address::getPointer` and `Lvalue::getPointer` that indicates whether the pointer is known not to be null

[Akira Hatanaka via Phabricator via cfe-commits]

================
Comment at: clang/lib/CodeGen/CGExpr.cpp:1723
+      Addr =
+          Addr.withPointer(Builder.CreateThreadLocalAddress(GV), KnownNonNull);
 
----------------
`KnownNonNull` is being passed here because the address of a load must be 
non-null. Do we have to check that the function doesn't have 
`null_pointer_is_valid` here?
