BTW. I think it should also be possible to simply attach a DW_AT_encoding directly to the DW_TAG_enumeration_type. It seems a simple oversight that option isn't listed in the current DWARF spec. I filed an issue about it: http://dwarfstd.org/ShowIssue.php?issue=161130.2 I haven't heard back from the committee. But Todd Allen from Concurrent said their Ada compiler already does this when generating DWARF Cheers, Mark
