It's not a stress test because it doesn't output lots of data and it's not a functional test because it only looks for raw trace output. It seems to imply that a program written in assembly influences whether trace would be generated by the CPU or not, but the CPU doesn't know what language the program is written in. We already have lots of Coresight tests that test the full pipeline including decoding, and in many more modes of operation than this one, so if no trace was collected they will already fail leaving this one redundant.
