Hello,
     I find DCE in sched2 is disabled for C6X backend. Is this a
performance consideration? Or a GCC BUG?
     And under what situations should we disable DCE in sched2?
     Can anyone explain this? Many thanks.
In general, if a port is disabling an optimization like this, then 
there's something wrong with the port.

As to this specific issue, git/svn blame ought to point you at whomever 
wrote this code and you can ping them directly.
