[PATCH] D62736: [clang-tidy] Fix make-unique check to work in C++17 mode.

[Dmitri Gribenko via Phabricator via cfe-commits]

+        }
+        if (CEArg->isStdInitListInitialization())
----------------
So `Foo(Bar{1, 2})` is not problematic, it is just that we can't tell it apart from `Foo({1,2})`?


================
Comment at: clang-tools-extra/test/clang-tidy/modernize-make-unique.cpp:457
   // CHECK-MESSAGES: :[[@LINE-1]]:28: warning: use std::make_unique instead
-  // CHECK-FIXES: std::unique_ptr<J> PJ2 = std::make_unique<J>(E{1, 2}, 1);
+  // CHECK-FIXES: std::unique_ptr<J> PJ2 = std::unique_ptr<J>(new J(E{1, 2}, 1));
   PJ2.reset(new J(E{1, 2}, 1));

Sorry I don't understand -- so what the file used to say, `std::make_unique<J>(E{1, 2}, 1)`, is correct, and this patch introduces a regression?  Or is some other syntax necessary?

Please add FIXMEs anyway.
