            Bug ID: 22833
           Summary: gold: --print-symbol-counts incorrect output ?
           Product: binutils
           Version: 2.29
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2

command line output that shows the behavior

The cmd option --print-symbol-counts seems to show incorrect counts for
imported symbols. I'm not completely sure what the output should be, but it
seems to me to be incorrect.

Example

main.c:
---
extern int num_one;
int main() {return num_one;}
---

libnum.c:
---
int num_one = 1;
int num_two = 2;
---

clang -c main.c
clang -c libnum.c 
clang -fuse-ld=gold -Wl,--cref -Wl,--print-symbol-counts,symbol-count.txt -o
main main.o libnum.o

symbol-count.txt
---
symbols libnum.o 2 2
---

Expected output would be

symbols libnum.o 2 1

2 exported symbols (num_one and num_two) and 1 used symbol (num_one) instead of
2 2.

Cross Reference Table (--cref) shows it correctly:

...
num_one                                           libnum.o
                                                  main.o
num_two                                           libnum.o
