Event Timeline

I am not at all confident that this implementation is correct, and I've opened an upstream issue at https://github.com/libcxxrt/libcxxrt/issues/35

This has now been merged upstream to libcxxrt at https://github.com/libcxxrt/libcxxrt/pull/36. This is the last change needed to permit building amd64 with GCC 14.

This revision is now accepted and ready to land.Aug 20 2024, 8:49 PM
