C1 intrinsics for CompareAndExchange (x86)

    XMLWordPrintable

    Details

      Description

      Most new Unsafe methods delegate to stronger variants in Unsafe.java, with the exception of new CompareAndExchange methods. compareAndExchange cannot be emulated with existing APIs. We need to intrinsify compareAndExchange methods separately.
