Hi @Allen, the codegen for the tests looks good to me and the optimisation seems sensible. However, I think perhaps what @paulwalker-arm meant was that we should set all expand types for all integer combinations to be Expand, then selectively mark some as Legal. Can you confirm this is what you meant @paulwalker-arm?
