There are also a ton of other bugs related to hard regs in reaching definitions
on df.c in mainline, i'm just guessing.
Try the df.c from the dataflow-branch, and see if it fixes the bug, because
honestly, i think you are barking up the wrong tree here.
Clobbers are most *certainly* not new definitions.
