+                                             const GlobalValue *GV) {
+  if (!TM.shouldAssumeDSOLocal(M, GV))
+    return false;
+  // A weak reference can end up being 0. If the code can be more that 4g away
----------------
It seems to me that the bug is in `shouldAssumeDSOLocal`: we should not assume we can use a copy relocation for a variable that might not be defined.
