           Summary: Allow DW_FORM_GNU_addr_index in Fission skeleton CUs
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab

gdb currently flags an error for DW_FORM_GNU_addr_index appearing in Fission
skeleton CUs.
There's no need for this restriction.

        * dwarf2read.c (read_attribute_value): Allow DW_FORM_GNU_addr_index
