Personally, I don't think this is a use case worth optimizing for. A match that open ended is bound to trip over other issues - reduce to the wrong crasher, etc. Anything vaguely precise enough to be useful probably isn't going to get tripped up by an attempt to use a calling convention incompatible with the target, I'd have thought?

What's the failure look like when you use a cc incompatible with the target? Does it fail in IR parsing?
