Hi,<br>
<br>
Please review this patch to move code out from PSParallelCompact
into ParCompactionManager.<br>
<br>
There is a circular dependency between between PSParallelCompact and
ParCompactionManager that makes it hard to move
ParCompactionManager::push to psCompactionManager.inline.hpp,
something that we need for <a
href="https://bugs.openjdk.java.net/browse/JDK-8076177"
title="Remove usage of stack.inline.hpp functions from
taskqueue.hpp">JDK-8076177</a>.
<br>
<br>
The circular dependency can be seen with:
<br>
<the follow contents functions in psCompactionManager.cpp>
<br>
PSParallelCompact::mark_and_push
<br>
ParCompactionManager::push
<br>
<br>
The suggested fix is to make mark_and_push a member of
ParCompactionManager. The implementation already takes a
ParCompactionManager as the first argument and it's used by other
ParCompactionManager specific functions.
<br>
<br>
The fix also moves the rest of the follow_* functions so that all
marking code, which is done in multiple threads using separate
ParCompactionManagers, are held together.
<br>
