一个JAVA编写的简单编译器

public class JSub {
  
  public static void main (String args[]) {
    util.Options.parseArgs (args);
    if (util.Options.getptestscan ()) {
      syntax.Scanner.scanAll (util.Options.getFileName ());
      return;
    }
    syntax.Parser p = new syntax.Parser (util.Options.getFileName ());
    if (!util.Options.getpnocodegen())
      codegen.WriteCode.setCodeFile (util.Options.getFileName ());
    p.parseClass ();
    if (util.Options.getpsymbol())
      p.dump ();
    if (!util.Options.getpnocodegen())
      p.codegen ();
    if (util.Options.getpgenxml())
      p.genXML (codegen.WriteCode.getXMLFile ());
  }
