- This manifested as non-determinism in the .inc output in rare cases (when two distinct patterns ended up being equivalent, which is rather rare). That meant the pattern matching was non-deterministic, which could eventually mean the code generator selected different instructions based on the arch. - It's probably worth making the DAGISel ensure a total ordering (or force the user to), but the simple fix here is to totally order the Record* maps based on a unique ID. - PR4672, PR4711.
