            Bug ID: 34826
           Summary: Duplicate data symbols don't report line numbers
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org
          Reporter: smeenai at fb.com

% cat /tmp/i.c
int i = 0;

% clang -g -o /tmp/i.o -c /tmp/i.c
% ld.lld /tmp/i.o /tmp/i.o
ld.lld: error: duplicate symbol: i
>>> defined at i.c
>>>            /tmp/i.o:(i)
>>> defined at i.c
>>>            /tmp/i.o:(.bss+0x0)

Note the lack of any line numbers in the error. For comparison, the error
message for a duplicate function symbol looks like

ld.lld: error: duplicate symbol: i
>>> defined at i.c:1 (/tmp/i.c:1)
>>>            /tmp/i.o:(i)
>>> defined at i.c:1 (/tmp/i.c:1)
>>>            /tmp/i.o:(.text+0x0)
