I believe the `toString` output for bound and unbound instructions should be identical and it can composed solely from methods on the public instruction interface. There are some differences e.g. `Increment` and `Inc` for the unbound and bound increment instruction respectively. If those assumptions are correct i recommend placing a static `toString` method on all unbound instructions that also have bound instructions, accepting the public instruction interface as an argument. Then the overridden `Object::toString` method defers to those. Thereby there is no duplication. (Alas we cannot override `toString` on the instruction interface itself). ------------- PR: https://git.openjdk.org/jdk/pull/10982
