public class PassException

extends java.lang.Exception

Various exceptions in passes.
When a compiler driver catches a PassException, it is expected that 1) the driver restores the contexts (i.e., HirRoot, LirRoot, etc.) in the state at prior to the beginning of the pass and restarts the compilation of the source file by going an alternative way, or 2) the driver abandons the source file, goes on the next source file and doesn't link object files.
PassException thrower must write an error message if it is required, because the compiler driver never writes it.
