Abstract
An embodiment generally pertains to a method of secure address handling in a processor. The method includes detecting an instruction that implicitly designates a target address and retrieving an encoded location associated with the target address. The method also includes decoding the encoded location to determine the target address. Another embodiment generally relates to detecting an instruction having an operand designating an encoded target address and determining a location of a target instruction associated with the target address. The method also includes determining a location of a subsequent instruction and encoding the location of the subsequent instruction. The method further includes storing the encoded location of the subsequent instruction.
