Presumably this branch should be removed since the store can't possibly write x2?

Good point. Definitely a cut and paste issue. I just removed the checks, since if the trigger didn't match then you end up with an unaligned exception which will cause the test to fail.

Same here. Or I guess if you're trying to make sure the store didn't write memory, you'd need to store a nonzero value and lb a byte of it back to see if it's still zero.
