[libcxx-commits] [PATCH] D75183: [libcxx] Guard C++20 atomic type aliases

[JF Bastien via Phabricator via libcxx-commits]

jfb added a comment.

Please add extensive tests, this will absolutely break in the future without them.



================
Comment at: libcxx/include/atomic:2756
     // No signed/unsigned lock-free types
+# define _LIBCPP_CANNOT_DEFINE_ATOMIC_LOCK_FREE_TYPE_ALIASES
 #endif
----------------
This should check that the configuration is indeed freestanding, and bail out if it's hosted.
