             Bug #: 55592

           Summary: linking with -flto always links in libgcc:s.so

    Classification: Unclassified

           Product: gcc

           Version: 4.8.0

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: lto

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: d...@gcc.gnu.org





$ cat foo.c 

int main() { }

$ gcc foo.c && ldd a.out |grep libgcc_s

$ gcc -flto foo.c && ldd a.out |grep libgcc_s

        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007fb214381000)



gcc.c (pass_through_libs_spec_func) doesn't pass the --as-needed/--no-as-needed

flags to the plugin. if these are passed, how should the plugin handle these?
