// Test if we build a mixed binary where one .o file has a .debug_names and
// another doesn't have one, that we save a full or partial index cache.
// Previous versions of LLDB would have ManualDWARFIndex.cpp that would save out
// an index cache to the same file regardless of wether the index cache was a
// full DWARF manual index, or just the CUs and TUs that were missing from any
// .debug_names tables. If the user had a .debug_names table and debugged once
// with index caching enabled, then debugged again but set the setting to ignore
// .debug_names ('settings set plugin.symbol-file.dwarf.ignore-file-indexes 1')
// this could cause LLDB to load the index cache from the previous run which
// was incomplete and it only contained the manually indexed DWARF from the run
// where we used .debug_names, but it would now load it as if it were the
// complete DWARF index.

// Test that if we don't have .debug_names, that we save a full DWARF index.
