So, assuming stptr is zero based, this means my `analysis of the behaviour of negative shift counts is correct.
My question, though, is more to ask if this was intended by design, or if it is a 'feature'? Intuitively, I would have expected this: CDEF:y=s,-n,x,PREDICT to result in shifts of s, 2s, 3s, .... ns However, it actually results in shifts of 0, s, 2s, ... (n-1)s Either way, it can't be changed now as it would potentially alter existing behaviour...
