[jdk17u-dev] RFR: 8293117: Add atomic bitset functions

Wed Dec 13 10:17:50 UTC 2023

Another clean backport to synchronize (pun intended) Atomics support across JDK releases, in order to simplify future backports and thus simplify maintenance. Nothing yet uses these atomics in 17u, so I did only the light testing for this patch.

Additional testing:
 - [x] macos-aarch64-fastdebug-server, new gtest passes
