tryPreempt

public static int tryPreempt(Target_java_lang_Continuation cont,
                             Thread thread)

isPinned

public static int isPinned(Target_java_lang_Thread thread,
                           Target_java_lang_ContinuationScope scope,

getSP

public static org.graalvm.word.Pointer getSP(Target_java_lang_Continuation cont)

getIP

public static org.graalvm.nativeimage.c.function.CodePointer getIP(Target_java_lang_Continuation cont)

setIP

public static void setIP(Target_java_lang_Continuation cont,
