This PR ensures that we use the same ordering to normalize linear `Int` terms and relations. This change affects `simp +arith` and `grind` normalizer. This consistency is important in the cutsat procedure. We want to avoid a situation where the cutsat state contains both "atoms": - `「(NatCast.natCast x + NatCast.natCast y) % 8」` - `「(NatCast.natCast y + NatCast.natCast x) % 8」` This was happening because we were using different orderings for (nested) terms and relations (`=`, `<=`). |
