================
Comment at: llvm/lib/Transforms/IPO/AttributorAttributes.cpp:2050
+            isa<ConstantPointerNull>(*SimplifiedVal.getValue()))
+          KnownUBInsts.insert(&I);
       }
----------------
While you are here, move the `isa` into the conditional above. No need to create/query an AA if it's not a nullptr.
