Generating protection barrier instructions for executable code

Provided are embodiments that include a system configured to generate executable code with protection barrier instructions. The system includes a storage medium, the storage medium being coupled to a processor. The processor is configured to analyze code, mark one or more potentially unsafe instructions in the code, and identify one or more unsafe instructions from the marked one or more potentially unsafe instructions in the code. The processor is also configured to insert a protection barrier instruction into the code based at least in part on identifying the one or more unsafe instructions, and translate the code, responsive to inserting the protection barrier instruction. Also provided are embodiments for a computer-implemented method and a computer program product for generating executable code with protection barrier instructions.
