            Bug ID: 16530
           Summary: --dynamic-list does not protect symbols from being
                    garbage collected
           Product: binutils
           Version: 2.25 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gold
          Assignee: ian at airs dot com
          Reporter: eugeni.stepanov at gmail dot com

$ cat z.cc
extern "C" void f() {}
int main() { return 0; }
$ cat z.syms 
{
  f;
};
$ g++ z.cc -o z -Wl,--dynamic-list,z.syms -Wl,--gc-sections -ffunction-sections
$ objdump -T z

With Gold linker (today's trunk), f is not exported from the executable. With
BFD linker, it is exported as a local(?) symbol.
