[David Majnemer via Phabricator via llvm-commits]

majnemer added inline comments.


================
Comment at: lib/Analysis/ConstantFolding.cpp:1779-1783
+    if (isa<ConstantPointerNull>(Operands[0])) {
+      if (IntrinsicID == Intrinsic::invariant_group_barrier)
         return Operands[0];
       return nullptr;
     }
----------------
Isn't this only valid if the address space is zero?
