Well, the changes I asked for related to the example in comment 0 are: - drop the import - change the tag from DW_TAG_compile_unit to DW_TAG_partial unit. AFAIU the patch only removes the import, so in that sense I do not consider the test-case reported in comment 0 addressed. I have not tried out the patch. FWIW, I did try a quick dwarf-assembly experiment (not the ada one, which will cost more time I expect, but modified gdb testsuite test-case gdb.dwarf2/imported-unit.exp) and confirmed that neither only removing the import nor only changing the tag is sufficient to get only one entry in the symtab. Anyway, I understand the example is somewhat abstract, and I'll file the actual ada example.
