> Hey @fhahn @nikic @mkazantsev can you please review this patch, I stumbled upon this while working on a bug in LSR, this patch does fail one of the unit test-case (scaling-factor-incompat-type.ll) in LSR. I believe that might be an effect of SCEV of this AShr pattern being computed, as LSR generally does do some optimizations based on the Shl + Add + AShr instructions.

ping ! Could you please take a look at this patch once.
