            Bug ID: 59319
           Summary: gcc does not emit DW_AT_friend or DW_TAG_friend
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tromey at gcc dot gnu.org

I couldn't find a way to make GCC emit DW_TAG_friend
or DW_AT_friend.  A quick grep through dwarf2out.c
seems to confirm this.
I think these are needed for gdb to properly implement ADL,
though I don't have an example ready.
