@johnregehr Found another tidbit about the PlayStation 3’s superoptimizer, if you’re interested https://news.ycombinator.com/item?id=21733922 …
Doesn’t sound fun :(

Replying to @pcwalton @johnregehr
I'm going to get a little salty at this idea that random search is "superoptimization". The whole point of someone inventing that silly word was to distinguish the bowdlerized "optimizers" (really improvers) from things that are going for actually optimal.

I always thought "superoptimizer" was kind of a misnomer already, since it's usually just "the shortest local inst. sequence", without even considering stuff like execution ports, etc. Adding more global effects like cache pressure/common input data makes "optimizing" hard

I know the word “superoptimizer” isn’t good terminology, but I use it anyway because people know what I mean. Same with “transpiler”.
