What is the purpose of llvm::make_unique?
<p>In llvm's compiler implementation tutorial (e.g. <a href="https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/LangImpl02.html" rel="nofollow noreferrer">here</a>) <code>llvm::make_unique</code> is used. What is the reason they aren't using <code>std::make_unique</code>? I wasn't able to find any clear documentation on this.</p>
