--- Comment #4 from Kenneth Graunke <kenneth at whitecape.org> ---
Oh, interesting.  Basically the entire time is spent in
fs_copy_prop_dataflow::run().  There are 2600 basic blocks and 5000 values. 
About 40% of them are constants, which could probably be handled separately to
avoid the dataflow costs (who cares what block it came from, it's an immediate,
you can just reconstruct it).  Not sure about undefined values.
