Hi David,
patch is pretty straight-forward, but since you came up with the idea I thought I’d give you a chance to nitpick first :-)
I rolled the addition of the public flag and the optimization into one commit, because I’m not going to update all the testcases twice (first for adding [public] and then for removing all the structs again).
cheers,
adrian

>> Honestly, probably the right fix is to add another flag (FlagPublic) and then just emit DW_AT_accessibility if one of the three flags is set. This would allow the frontend to omit the flag even for members, if their accessibility is the default (eg: public members in structs, private members in classes) - it's something I've seen GCC do that Clang doesn't (could be a very minor DWARF size reduction benefit).
