[PATCH] D61838: [Sema] Suppress additional warnings for C's zero initializer

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added inline comments.


================
Comment at: clang/lib/AST/Expr.cpp:2092-2096
   const IntegerLiteral *Lit = dyn_cast<IntegerLiteral>(getInit(0));
+  if (!Lit) {
+    if (const ImplicitCastExpr *ICE = dyn_cast<ImplicitCastExpr>(getInit(0)))
+      Lit = dyn_cast<IntegerLiteral>(ICE->getSubExpr());
+  }
----------------
Use `Expr::IgnoreImplicit` rather than checking for an `ImplicitCastExpr` here:

```
const IntegerLiteral *Lit = dyn_cast<IntegerLiteral>(getInit(0)->IgnoreImplicit());
```
