I fear the covered check will hit us perf wise either way (+CC some people from our GPU team) and that we need to find a different solution long term (like the Targets announcing the saved registers themselfes instead of the generic code piecing together the information...).
Anyway if this works for you I'd be fine with this patch as a stopgap.
