; This testcase contains a entire loop that should be removed. The only thing
|
|
; left is the store instruction in BB0. The problem this testcase was running
|
|
; into was that when the reg109 PHI was getting zero predecessors, it was
|
|
; removed even though there were uses still around. Now the uses are filled
|
|
; in with a dummy value before the PHI is deleted.
