At this point, I cannot determine whether current execution is in extreme or medium code mode, since I cannot obtain the next relocation record. So, as a workaround, I have chosen to convert the relocation type in both modes and then restore it(extreme code mode) or relax it(medium code mode) later in relocateAlloc.
