public boolean isSuppressedFailure(CompilableTruffleAST compilable,
                                   Supplier<String> serializedException)
```
    Description copied from interface: TruffleCompilerRuntime
    
    Determines if the exception which happened during the compilation is suppressed and should be silent.
    
    Specified by:
    
    isSuppressedFailure in interface TruffleCompilerRuntime
  - isSuppressedTruffleRuntimeException
```
protected boolean isSuppressedTruffleRuntimeException(Throwable throwable)
```
    Allows GraalTruffleRuntime subclasses to suppress exceptions such as an exception thrown during VM exit. Unlike GraalTruffleRuntime.isSuppressedFailure(CompilableTruffleAST, Supplier) this method is called only for exceptions thrown on the Truffle runtime side, so it does not need to stringify the passed exception.
  - openCompilerThreadScope
```
protected AutoCloseable openCompilerThreadScope()
```
    Gets a closeable that will be used in a try-with-resources statement surrounding the run-loop of a Truffle compiler thread. In conjunction with GraalTruffleRuntime.getCompilerIdleDelay(OptimizedCallTarget), this can be used to release resources held by idle Truffle compiler threads. If a non-null value is returned, its AutoCloseable.close() must not throw an exception.
  - getCompilerIdleDelay
```
protected long getCompilerIdleDelay(OptimizedCallTarget callTarget)
```
    Gets the time in milliseconds an idle compiler thread will wait for new tasks before terminating. A value of <= 0 means that compiler threads block indefinitely waiting for a task and thus never terminate.
  - getOptionsForCompiler
```
public static Map<String,Object> getOptionsForCompiler(OptimizedCallTarget target)
```
    Returns OptimizedCallTarget's PolyglotCompilerOptions as a Map. The returned map can be passed as a options to the TruffleCompiler methods.
  - getObjectAlignment
```
protected int getObjectAlignment()
```
  - getArrayBaseOffset
```
protected int getArrayBaseOffset(Class<?> componentType)
```
  - getArrayIndexScale
```
protected int getArrayIndexScale(Class<?> componentType)
```
  - getBaseInstanceSize
```
protected int getBaseInstanceSize(Class<?> type)
```
  - getResolvedFields
```
protected Object[] getResolvedFields(Class<?> type,
                                     boolean includePrimitive,
                                     boolean includeSuperclasses)
```
  - getFieldValue
```
protected Object getFieldValue(ResolvedJavaField resolvedJavaField,

```
