             Bug #: 13287
           Summary: g++ -Wl,--as-needed -flto doesn't work with the BFD
                    linker, but with gold
           Product: binutils
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


seen with the 2.22 branch (and the fix for pr13250 applied), works with gold,
gcc is 4.6 from the branch.


$ cat foo.cc 
int main() {}

$ g++ -B/usr/lib/gold-ld/ -Wl,--as-needed -flto foo.cc
ok

$ $ gcc -Wl,--as-needed -flto foo.cc
ok

$ $ g++ -Wl,--as-needed -flto foo.cc
