[libcxx-commits] [PATCH] D68480: Implementation of C++20's P1135R6 for libcxx

[Olivier Giroux via Phabricator via libcxx-commits]

__simt__ updated this revision to Diff 245055.
__simt__ added a comment.

This revision addresses the outstanding comments, and incorporates Louis' recommended macros for ulock detection.

I also added missing max() members to barrier/latch that were added by NB comment resolution, and I implemented the normative encouragement for the lock-free types to match the ideal contention type, if there is one. I added tests for these things.

Finally, I further improved the ABI resilience of the barrier type so it's almost a full pimpl now.
