Does this technique limit the LLM to correctness-preserving transforms?

I'm really excited about this, especially for games for which the source code was lost like Red Alert 2.

"Claude struggles with large functions and more or less gives up immediately on those exceeding 1,000 instructions." Well, yeah, that's the thing, an n64 game, that's C targetting an architecture where compiler optimizations are typically lacking, the idomatic style is lots of small tightly-scoped functions and the system architecture itself is a lot simpler than say a modern amd64 pc... These days I often just feel like, why is this person telling me how easy my job is now when they seemingly don't know much about it. I just find it arrogant and insulting... Perpetually demo season.
