#include "j9.h"

/* Stub methods called from files in the runtime/bcutil directory.
 *
 * These functions are called using the following macros which
 * 	* J9_VM_FUNCTION(currentThread, function)
 *	* J9_VM_FUNCTION_VIA_JAVAVM(javaVM, function)
 * allow them to be direct calls or indirect through the 
 * internalVMFunctions table.
 *
 * The bcutil directory is compiled as a static library with
 * `J9_INTERNAL_TO_VM` defined so the calls appear to be direct.
 *
 * cfdump needs to stub some of these functions to allow the
 * bcutil static library to be linked.  This avoids the following
 * link errors:
 *
 *
 * "_freeMemorySegment", referenced from:
 *    _internalDefineClass in libj9dyn.a(defineclass.o)
 * "_internalCreateRAMClassFromROMClass", referenced from:
 *    _internalDefineClass in libj9dyn.a(defineclass.o)
 * "_setCurrentException", referenced from:
 *    _internalDefineClass in libj9dyn.a(defineclass.o)
 * "_setCurrentExceptionUTF", referenced from:
 *    _internalDefineClass in libj9dyn.a(defineclass.o)
