Do not run if compile progress has been cancelled

Can this transform change the base types of a type?

Can this transform create or delete non-private members?

Can this transform change the parents of a class?

Check what the phase achieves, to be called at any point after it is finished.

The sequence position of this phase in the given context where 0 is reserved for NoPhase and the first real phase is at position 1. -1 if the phase is not installed in the context.

Output should be checkable by TreeChecker

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).

Cancellable region, if not cancelled, run the body in the context of the current compilation unit. Enrich crash messages.

If set, allow missing or superfluous arguments in applications and type applications.

List of names of phases that should precede this phase

Convert a compilation unit's tree to a string; can be overridden

for purposes of progress tracking, overridden in TyperPhase

Returns a string representation of the object.

The default representation is platform dependent.

A name given to the Phase that can be used to debug the compiler. For instance, it is possible to print trees after a given phase using:

$ ./bin/scalac -Xprint:<phaseNameHere> sourceFile.scala
