| // 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. |
| |
