[PATCH] D58035: [clang/DIVar] Emit flag for params that have unchanged values

[Adrian Prantl via Phabricator via cfe-commits]

aprantl added inline comments.


================
Comment at: lib/CodeGen/CGDebugInfo.cpp:3885
+  if (ArgNo) {
+    auto *PD = dyn_cast<ParmVarDecl>(VD);
+    ParmCache[PD].reset(D);
----------------
A `dyn_cast` followed by an unconditional use seems strange. I would expect either a `cast` or an `if (PD)` check.
