utilizing volatile variables of type long (and double)
[ https://issues.apache.org/jira/browse/HARMONY-2102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
George Timoshenko updated HARMONY-2102:
---------------------------------------
Attachment: Test.java
Here is a possible "benchmark".
It is based on Mikhail Fursov test from HARMONY-2092
Egor, do you think the test is suitable?
On this test Jrockit is about 2 times faster than DRLVM with CMPXCHG8B solution (see 2092)
