a Sample for Sparc backend

[Bahram Yarahmadi]

Hello guys,
I want to generate code for different ISAs ( for example SPARC which is
currently in graal code base) before migrating to old revisions ( my main
target is PTX)
I have written a very simple program ,that is :
   RuntimeProvider runtimeProvider =
Graal.getRequiredCapability(RuntimeProvider.class);
   Backend backend = runtimeProvider.getBackend(SPARC.class);
   Providers providers=backend.getProviders();
   MetaAccess   metaAccess = providers.getMetaAccess();
   CodeCache  codeCache = providers.getCodeCache();
    ResolvedJavaMethod method = findMethod(ScrachTest.class,
"AddTwoNumbers"); //ScrachTest.class is a simple class with a method in it
    StructuredGraph graph = new StructuredGraph(method,
AllowAssumptions.YES);
    PhaseSuite<HighTierContext> graphBuilderSuite =
 backend.getSuites().getDefaultGraphBuilderSuite();
        Suites suites = backend.getSuites().getDefaultSuites();
        LIRSuites lirSuites = backend.getSuites().getDefaultLIRSuites();

        OptimisticOptimizations optimisticOpts =
OptimisticOptimizations.ALL;
        ProfilingInfo profilingInfo = graph.getProfilingInfo(method);
        CompilationResult compilationResult = new CompilationResult();
        CompilationResultBuilderFactory factory =
CompilationResultBuilderFactory.Default;
         GraalCompiler.compileGraph(graph, method, providers, backend,
graphBuilderSuite,
         optimisticOpts, profilingInfo, suites, lirSuites,
compilationResult, factory);
         CompiledCode compiledCode = backend.createCompiledCode(method,
compilationResult);
        InstalledCode installedCode = codeCache.addCode(method,
compiledCode, null, null);
When I want to test my program I get these Errors
(com.oracle.graal.compiler.test.tutorial.GraalTutorial)
java.lang.NullPointerException

Could you please tell me how can I generate code for different ISAs ?

Thanks
