-                                         DVar.CKind != OMPC_private))) ||
-             ((isOpenMPWorksharingDirective(DKind) || DKind == OMPD_taskloop ||

-               DKind == OMPD_parallel_master_taskloop ||
-               isOpenMPDistributeDirective(DKind)) &&
-              !isOpenMPSimdDirective(DKind) && DVar.CKind != OMPC_unknown &&
-              DVar.CKind != OMPC_private && DVar.CKind != OMPC_lastprivate)) &&
-            (DVar.CKind != OMPC_private || DVar.RefExpr)) {
+            : DVar.CKind == OMPC_lastprivate ? OMPC_lastprivate
+                                             : OMPC_private;
----------------
Why need this change?


================
Comment at: clang/lib/Sema/SemaOpenMP.cpp:8662-8667
+        if (LangOpts.OpenMP > 45 && isOpenMPSimdDirective(DKind)) {
+          if (DVar.CKind == OMPC_lastprivate)
+            PredeterminedCKind = OMPC_lastprivate;
+          else if (DVar.CKind == OMPC_private)
+            PredeterminedCKind = OMPC_private;
+        }
----------------
Again, why do we need this?
