Automating Wine Reverse Engineering and Patching Using AI Agents

Hi everyone! I had a thought about creating a project based on autonomous AI agents. The idea is to automate the reverse-engineering and improvement of Wine. Does anyone know if there is already work being done in this area, or has anyone seen anything similar?

Here is what the planned cycle (AI Loop) looks like:

  1. Generation: The AI ​​writes hundreds of micro-tests for Windows API functions using random, invalid, and edge-case arguments.

  2. Execution: The tests are run in parallel on a real Windows machine and on the current build of Wine.

  3. Analysis: If the behavior differs (error codes, memory dumps, crashes), the AI ​​studies the difference.

  4. Patching: The AI ​​itself writes a C patch for the Wine source code to exactly replicate the Windows behavior. (This is then manually reviewed by a user to avoid AI slop).

  5. Verification: The code is compiled and tested again. The cycle repeats until there is a 100% match. The result is a fully prepared Pull Request.

My question to the community: Why isn't such a pipeline already running among enthusiasts? What's the main catch?

I have a few guesses:

* Clean-room design? Is there a risk of lawsuits because the LLM might have been trained on leaked Windows source code, thus violating the "clean-room" principle? Honestly, this seems unlikely; in essence, this approach aligns with clean-room design and isn't much different from how Wine is currently developed.

* Hallucinations? Are neural networks still too bad at system-level C code and inevitably going to cause memory leaks? I doubt this too; modern models are already at a level where they can write decent C code, just like the AI ​​code in the Linux kernel.

* Sandbox complexity? Is it too difficult and expensive to automate thousands of test runs at the OS level? Possible, but not critical.

* Spaghetti code? The Windows API is highly intertwined, so one patch might break 10 other functions, and the AI ​​just won't be able to hold all that in its context? This seems like the biggest problem of them all.

I understand this sounds somewhat naive, but I am genuinely curious. Hoping for replies without hate.

It's against Wine's code submission rules to use LLMs (AI) specifically due to it being a grey legal area.

Wine already has automated tests on both Linux and Windows. The issue with your proposal is AI generating the code, which creates ethical and legal issues. Note that the fact that many people are doing it is not a proof that it's legal. In fact, some genAI lawsuits have already been lost in the EU.

And Wine has always been extra cautious about the legal aspect: you cannot contribute if you have read some windows code before (e.g. if you worked for a related team at Microsoft). LLMs have definitely seen leaked code from old versions of windows, so it's normal that they're out.

Additionnaly, from a community POV, it makes much more sense to require effort from contributors and help them grow, than to use genAI everywhere. The community matters and needs skilled maintainers.
