-// run-pass
-// This test deserializes an enum in-place by transmuting to a union that
-// should have the same layout, and manipulating the tag and payloads
-// independently. This verifies that `repr(some_int)` has a stable representation,
-// and that we don't miscompile these kinds of manipulations.
