Abstract
A method, computer program product and/or system is disclosed. According to an aspect of this invention, one or more processors receive an indirect jump instruction comprising a target address offset and a maximal offset value. One or more processors determine whether the target address offset is valid by comparison of the target address offset and the maximal offset value and one or more processors execute a jump operation based on whether the target address offset is valid. In some embodiments of the present invention, the jump operation comprises one or more processors executing an instruction located at a target address referenced by the target address offset if the target address offset is valid. In some embodiments, the jump operation further comprises one or more processors raising an exception if the target address offset is not valid.
