...undesirable on my target. I wonder if there is any way to tell LSR to not duplicate the code in cases like this? Or could I perhaps run CSE after LSR again? What is the logic behind this transformation? It seems that a LSR pass should not insert a multiplication, generally..?

...c behind this is that on many targets these extra instructions are absorbed into the 'addressing mode' of the user instructions.
