Hi Florian, I think when you define an alias with repeated operands you need to additionally define checkEarlyTargetMatchPredicate in your target to make sure that a if you are trying to build an "orr" instruction coming from a "mov" instruction, the mov instruction coming in has the right tied operands. Otherwise you reject the match. This warning causes failure in an build with asserts enabled.
