             Bug #: 14918
           Summary: linking with -flto always links in libgcc:s.so
           Product: binutils
           Version: 2.23
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


checked with the 2.23 branch (and gcc-4.7), original report at
http://gcc.gnu.org/PR55592

$ 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)

works with gold:
$ gcc -B /usr/lib/gold-ld -flto foo.c && ldd a.out |grep libgcc_s
$ 

libgcc is linked as:
-lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s
--no-as-needed
