// This class defines a simple subclass of User, which keeps a pointer to a
|
|
// Value, which automatically updates when Value::replaceAllUsesWith is called.
|
|
// This is useful when you have pointers to Value's in your pass, but the
|
|
// pointers get invalidated when some other portion of the algorithm is
|
|
// replacing Values with other Values.
