relates to:

• SR-13827 LLDB not launching on Windows

Issue Description:

LLDB shipped with Swift Windows toolchain explicitly links against `python37.dll` or `python39.dll`, which is not forward-compatible with newer Python.

This is tracked by llvm/llvm-project#53738 in LLVM upstream project. We should follow once the change lands, and it will also enable us to use newer Python to build Swift.

The official builds use Python3.9 at this point (or should be using 3.9 as that is what the current version is in VS).

[stevapple]

I don’t think the problem has really been solved.

We should not fix Python to any specific version. Instead, moving to use stable interface and setting a minimal required version.

LLVM people have already taken the initiative to fix this on their side.

@stevapple this sounds really interesting. Do you have any pointers on this? It would be far better to avoid the specific version dependency. Do you think that you would have the time to help get us there?
