abstract class RefChecks extends SubComponent with Transform
Post-attribution checking and transformation.
This phase performs the following checks.
- All overrides conform to rules.
- All type arguments conform to bounds.
- All type variable uses conform to variance annotations.
- No forward reference to a term symbol extends beyond a value definition.
It performs the following transformations.
- Local modules are replaced by variables and classes
- Calls to case factory methods are replaced by new's.
- Eliminate branches in a conditional if the condition is a constant
