Hi Please review the following webrev which combines:
8161444 VarHandles should provide access bitwise atomics 8162107 Add acquire/release variants for getAndSet and getAndAdd http://cr.openjdk.java.net/~psandoz/jdk9/JDK-8161444-vhs-bitwise-atomics/webrev/ http://cr.openjdk.java.net/~psandoz/jdk9/JDK-8161444-vhs-bitwise-atomics/specdiff/overview-summary.html The set of access modes are expanded for support bitwise or/and/xor operations for volatile/acquire/release. Acquire/release getAndAdd and getAndSet access modes are also added (a future webrev will remove getAndAdd). This gets closer to parity with C++ atomics. As a follow on i will: - update the Hotspot Unsafe tests as a separate issue (the VarHandle tests implicitly test the Unsafe methods). - log HotSpot bugs for making the Unsafe bitwise atomics intrinsic for various platforms. Thanks, Paul.
