Abstract
A processor can be used to ensure that program code can only be used for a designed purpose and not exploited by malware. Embodiments of an illustrative processor can comprise logic operable to execute a program instruction and to distinguish whether the program instruction is a legitimate branch instruction or a non-legitimate branch instruction.
