@compnerd, @vgvassilev this patch works-around a few LLVM unit tests that use internal interfaces by linking them statically with the LLVM component libraries they depend on instead of against the LLVM DLL. There are already a number of unit tests that were already building this way. The alternative solution is to annotate some headers under llvm/lib with `LLVM_ABI` even though they're not part of the public ABI. I think the approach in this PR is preferable, but I would appreciate your feedback. Thanks!
