tberghammer added a comment. My understanding (can be wrong) is that there IS a difference between not specifying a register in the unwind info versus specifying it as "is same" for volatile (caller saved) registers. I think for volatile registers not specifying them means that we can't access their current value in the parent frame (because they are lost) while specifying them as "is same" means we know that their value in the parent frame is the same as in the current one so we can display them.
If "is same" and "not specified" would be equivalent then we should just completely get rid of the "is same" case (as it is useless) but as far as I know they have subtle differences.
