      We recently got several reports of incorrect results of C2 compiled code since JDK-8237581 in JDK 15 b10. They all seem to have the same root cause, so I moved them to subtasks of this issue and closed them as duplicates. The regression tests provided in these reports should be added to the final fix.

      If investigation shows that some of the issues are independent, they should be converted to separate bugs again.
