Hi Alex,
I think the 70% increase when recording all of the registers is too much, so we should continue with the change
to only record the link register. In my opinion a 5% - 10% increase by enabling LR recording by default wouldn't
be noticeable, so it's worth doing. But obviously we'll need other opinions too.
Do you also have the average stack lengths for these figures?
