So, I did some tests. I setup afl++ with a static seed and went through some minutes of fuzzing on both x86 and s390x. Results are as expected: - many tests(~50%) result in the same error message - others result in different error messages - I could not find a crash (note that i tested only a limited time) at this stage I am hesitating to go forward and try to fix all cases where hardware and software implementation generate different error messages. I think we are at a solid state here, as both implementations run with the same test suit. Investing more time to get a 100% error message overlap looks like a bigger effort. We know that the hardware state machine does not simply map the software, so I fear that it will result in very very cumbersome error handling code. > > > -- > Eduard Stefes <eduard.ste...@ibm.com>
