Giv optimizations are just features which not
implemented yet in the new loop unroller, so I think
put it in bugzilla is not appropriate.
Bugzilla should be used more than just normal bugs but
also enhancements.
I test 171.swim on IA64 system with 1GHz itanium2 CPU.
Note you with -ftree-loop-linear you will most likely get
better performance out of swim than another other
optimization that is normally done as one of the loops in
swim is really reversed in transversing the array.
