I guess I'm late but still. It might make sense to split instruction definitions and patterns. E.g. extract pattern for i32 load from L32I definition and put it here together with other patterns for loads.
This will make instruction definitions more readable and patterns grouped so that you don't have to look through the entire file when searching for them.
