[PATCH] D88207: [ValueTracking] Check uses of Argument if it is given to isGuaranteedNotToBeUndefOrPoison

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:4889
+    if (programUndefinedIfUndefOrPoison(A, PoisonOnly))
+      return true;
   }
----------------
I would prefer to move the programUndefinedIfUndefOrPoison() call below outside the Instruction check, and  just return false from programUndefinedIfUndefOrPoison()  on non-Instruction/Argument (aka Constant).
