-; This test checks for proper handling of a condition where the greedy register
-; allocator encounters a very short interval that contains no uses but does
-; contain an EH pad unwind edge, which requires spilling.  Previously the
-; register allocator marked a interval like this as unspillable, resulting in
-; a compilation failure.
