Result

The primitive succeeded, and the result, if any, has been stored for subsequent use in the Interpreter.latestResult.

The primitive failed. The backup Avail code should be executed instead.

The continuation was replaced as a consequence of the primitive. This is a specific form of success, but no result can be produced due to the fact that the new continuation does not have a place to write it.

A primitive with Flag.CanInline and Flag.Invokes has set up the Interpreter.function and Interpreter.argsBuffer for a call, but has not called it because that's not permitted from within a Primitive.

The current fiber has been suspended as a consequence of this primitive executing, so the interpreter should switch processes now.

The CheckedField for this instance.
