@Override public boolean isSysCall(Instruction s){
  return s.operator() == PPC_BCTRL_SYS || s.operator() == PPC_BL_SYS;
}

@ Override public boolean isSysCall ( Instruction s ) { return s . operator ( ) == PPC_BCTRL_SYS || s . operator ( ) == PPC_BL_SYS ; }
is a particular instruction a system call ?
