[libcxx-commits] [PATCH] D72240: Implement C++20 std::atomic_ref and test

[Benjamin Trapani via Phabricator via libcxx-commits]

BenjaminTrapani updated this revision to Diff 237524.
BenjaminTrapani added a comment.

Get rid of duplication across __cxx_atomic_* functions by using a traits class and SFINAE to check types and select overrides when required. Static assert that template type is always lock free when built using builtin only mode.
