| // 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. | |
