[libcxx-commits] [PATCH] D75156: Some fixes for open breaks on MacOS and UBSan

[Olivier Giroux via Phabricator via libcxx-commits]

__simt__ created this revision.
Herald added subscribers: libcxx-commits, ldionne.

In this patch:

1. Reduced the net of dependencies when platform semaphores are disabled.
2. Respect the signed range of ptrdiff_t in tests.
3. Construct the aligned member for the barrier algorithm properly.

Testing on this code is pretty light at this stage.
