Nice -- I've been wanting to do that for a while, but I always thought it would be a lot harder. I see that you've based this on the infrastructure created for -feliminate-dwarf2-dups. I don't think that will play nice with -fdebug-types-section, though, since I basically made those two options incompatible with each other by unioning die_symbol with die_type_node.
I think it should be OK because I wait until after the debug_types processing is done, at which point limbo_die_list is empty. Or am I just not seeing the problem?
In the HP-UX compilers, we basically put a complete set of .debug_* sections in each COMDAT group, and treated the group as a compilation unit of its own (not a partial unit).
So you copy anything that the function refers to into the CU for the function?
wasteful in terms of object file size). Readelf and friends will need to be taught how to find the right auxiliary debug sections, though -- they currently have a built-in assumption that there's only one of each.
Good to know. Jason
