The interface changes look all right, to me at least. I'm not too familiar with generating split-file debug info, but I imagine it's possible to do so with some flags to GCC (if not Clang)? If so, can you add some tests that do that too? I'd love to see this functionality go in and stay unbroken :)<br>
<br>
In any case, it's probably best to have someone else with more object file experience review the patch too as my knowledge is somewhat limited in that dept. I'll post any comments I might come up with on phabricator.</div>

I'm building lldb with cmake+ninja, and debugserver with "xcodebuild -scheme debugserver", then I set LLDB_SERVER_PATH and everything is working a lot more consistently for me. I also got the tests to run and fixed a couple of Mac bugs. So the latest patch is updated here:</div>
