Abstract
In one embodiment, after translating a plurality of target instructions from a target memory location into a plurality of host instructions, a write operation to a target memory portion which includes said target memory location is detected. In response to the detecting, a copy of the target instructions is stored in a host memory. In response to an attempt to execute the host instructions, the copy is compared with a plurality of current target instructions presently stored in the target memory location. Further, in response to a mismatch based on the comparison, the host instructions are disabled.
