I don't mind dropping the patch, we can mitigate the problem in Wine. My understanding is that we could use "pedantic" logic similar to NSInteger in checkFormatExpr, please let me know if you'd like something like that.

With the solution for UWP, we don't have a use case .drectve change, so dropping that part sounds reasonable.

Yes, it works with your patch and Wine workaround reverted.

I can confirm that with a simple Wine change, its importlibs work fine.

Oh, I see. FWIW, it shouldn't be too hard to work around the problem in Wine. .def file is generated automatically, so we could just skip aliases for .def file used for importlibs. It seems like it would help a hypethetical Wine MSCV port anyway and it might be better for LLVM to be MSVC compatible in this case. I will experiment with it.

It looks like decoration is killed too aggressively now. If aliasee symbol has no decoration, aliased symbol is stripped. For example:

Thanks for doing that!

Thanks for review.

Thanks for reviews, I addressed comments.
