For ARCompact, doloop loops in particular were interesting to
optimize, which is why I have a patch to loop-doloop.c in

2009-02-24  J"orn Rennecke  <joern.renne...@arc.com>

         * loop-doloop.c (doloop_valid_p): Rename to:
         (validize_doloop).  Try to fix up loops with conditons for 
infinite
         looping by enclosing them in an outer loop.
         Changed caller.
         (add_test): Add new parameter edgep.  Changed caller.

This looks interesting, but unless I read the svn log incorrectly, the 
arc branches have all patches applied in a single commit, which isn't 
exactly useful.  Do you have them broken-out somewhere?
