Zachary Turner ab480f45cd [Support] Add support for unique_ptr<> to Casting.h. ... Often you have a unique_ptr<T> where T supports LLVM's casting methods, and you wish to cast it to a unique_ptr<U>. Prior to this patch, this requires doing hacky things like: unique_ptr<U> Casted; if (isa<U>(Orig.get())) Casted.reset(cast<U>(Orig.release())); This is overly verbose, and it would be nice to just be able to use unique_ptr directly with cast and dyn_cast. To this end, this patch updates cast<> to work directly with unique_ptr<T>, so you can now write: auto Casted = cast<U>(std::move(Orig)); Since it's possible for dyn_cast<> to fail, however, we choose to use a slightly different API here, because it's awkward to write if (auto Casted = dyn_cast<U>(std::move(Orig))) {} when Orig may end up not having been moved at all. So the interface for dyn_cast is if (auto Casted = unique_dyn_cast<U>(Orig)) {} Where the inclusion of `unique` in the name of the cast operator re-affirms that regardless of success of or fail of the casting, exactly one of the input value and the return value will contain a non-null result.
