             Bug #: 13992
           Summary: -Wl strips empty options
           Product: clang
           Version: 3.1
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Driver
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: l.lunak at suse.cz
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


When using e.g. 'clang++ -Wl,rpath,' , the empty option at the end is skipped
and not passed to the linker, unlike with gcc, which does pass the option.

The difference can be observed e.g. by running 'strace -f -e execve -s 100
clang++ -Wl,-rpath,' and checking the options passed to ld.
