// If a struct has exactly two variants, one of them is empty, and the other one
|
|
// contains a non-nullable pointer, then this value is used as the discriminator.
|
|
// The test cases in this file make sure that something readable is generated for
|
|
// this kind of types.
|
|
// If the non-empty variant contains a single non-nullable pointer than the whole
|
|
// item is represented as just a pointer and not wrapped in a struct.
|
|
// Unfortunately (for these test cases) the content of the non-discriminant fields
|
|
// in the null-case is not defined. So we just read the discriminator field in
|
|
// this case (by casting the value to a memory-equivalent struct).
