Functional test of processor code modification operations

A computing system comprising:

• a memory;
• and
• a processor comprising a processor pipeline, the processor pipeline comprising one or more execution units configured to execute a first thread;
• and
• execute a second thread concurrently with the execution of the first thread, the second thread being executed to modify the first thread using a code modification operation;
• and
• a test module configured to validate a functionality of the code modification operation based on a result of the modified first thread.

A computer-implemented method comprising:

• executing, by a processor, a first thread;
• executing, by the processor, a second thread concurrently with the execution of the first thread, the second thread being executed to modify the first thread using a code modification operation;
• and
• validating, by the processor, a functionality of the code modification operation based on a result of the modified first thread.
