But hopefully > you mean something else? I realize we can't include the code for final release. But as a temporary measure I was hoping we would put in the code, we could allow somebody more familar with ccp to debug it. Then if there were changes needed in the PowerPC back end, we could make them, once ccp was fixed. But that is a moot point, ccp no longer dies with the code, so I have removed the comment and the no tree ccp option in the next set of patches. -- Michael Meissner, IBM PO Box 98, Ayer, Massachusetts, USA, 01432 email: meissner@linux.ibm.com
