[Nick Desaulniers via Phabricator via cfe-commits]

nickdesaulniers added inline comments.


================
Comment at: clang/lib/CodeGen/CGExprConstant.cpp:1131-1132
+    case CK_NullToPointer: {
+      if (llvm::Constant *C = Visit(subExpr, destType))
+        if (C->isNullValue())
+          return CGM.EmitNullConstant(destType);
----------------
FWIW, I would have thought these might be unnecessary, but we do trip 2 tests without these guards IIRC.
