Here, all DLLs are expected to use the same ABI (either the implicit one based on the LLDB build). D127234 <https://reviews.llvm.org/D127234> is a follow-up that allows you to set a specific ABI choice per DLL. > 3.

It's possible to make heuristic guesses based on e.g. what DLLs they import, but it's all guesses, possibly brittle. Having an option allows you to get it right even for the cases where the default is wrong. > 4. What more information can we get from debug info in this case?

Exactly, one could use presence of DWARF as a heuristic hint for this, but it's not always right (you can use PDB for mingw uses too, and DWARF for msvc abi too in uncommon cases).
