[PATCH] D153296: [AST] Stop evaluate constant expression if the condition expression which in switch statement contains errors

[Erich Keane via Phabricator via cfe-commits]

erichkeane added inline comments.


================
Comment at: clang/lib/AST/ExprConstant.cpp:4988
+      if (SS->getCond()->containsErrors() ||
+          !EvaluateDependentExpr(SS->getCond(), Info))
         return ESR_Failed;
----------------
It seems to me that the 'better' solution is to make EvaluateDependentExpr (or one of its children) be RecoveryExpr aware, and result in a failed value instead.  That way we get this 'fix' for more than just switch statements.
