[PATCH] D112579: Allow non-variadic functions to be attributed with `__attribute__((format))`

[Félix Cloutier via Phabricator via cfe-commits]

fcloutier added a comment.

I'm afraid that's also not possible: `D` is a `Decl`, so it doesn't have `getType()`. `Decl` is the tightest-fitting superclass of `BlockDecl`, `FunctionDecl` and `ObjCMethodDecl` (because `BlockDecl` is a direct subclass of it).

One option could be to cast the `Decl` to a `FunctionDecl` and then use `FDecl->isVariadic()`, similarly to how it goes for `BlockDecl` and `ObjCMethodDecl`. I'm not sure that it's equivalent, but if you believe it is and like it better, I can do that.
