I believe the backend would still need work to make sure this is supported, which has not been done yet. I was expecting it to fail more noisily, but it appears the strict nodes are lowered to generic nodes. That doesn't mean that strict-fp is supported by the Arm backend, as it might not handle the instructions correctly at the moment (moving instructions past one another, for example).
