| # This YAML file will create a .dwp file that has a DWARF32 compile unit whose |
| # .debug_str_offsets.dwo is in DWARF64 format. This test verifies that |
| # llvm-dwarfdump can read the strings correctly and dump the |
| # .debug_str_offsets.dwo info correctly. This paves the way for llvm-dwp to |
| # promote some .debug_str_offsets tables for .dwo files to be DWARF64 and will |
| # allow the .debug_str section to be larger than UINT32_MAX size in bytes |
| # without losing data. |
