…3357) This PR rewrites ``` varith.add %n, %n, %n, %x ``` as ``` %three arith.constant 3 %three_n = arith.mulx %n, %three // mulf or muli %varith.add %three_n, %x ``` This is useful in particular when operating on tensors, in order to avoid repeatedly adding a large tensor to itself (we have such a case). The number of repetitions minimally required to trigger fusion behaviour can be controlled via a flag (default=2). Co-authored-by: n-io <[email protected]>
