| ## This tests dumping a .debug_str_offsets.dwo section in a DWP file when it is |
| ## referenced by units in different formats: one unit is DWARF32 and another |
| ## is DWARF64, thus the .debug_str_offsets.dwo section has contributions with |
| ## different sizes of offsets. |
| ## This also checks that attributes in the units which use the DW_FORM_strx form |
| ## are dumped correctly. |
