            Bug ID: 39274
           Summary: The combination of -static-libstdc++ and
                    -stdlib=libc++ links in both standard libraries
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org

The -static-libstdc++ option will blindly add a "-lstdc++" option, even if we
have -stdlib=libc++ and we're also getting a "-lc++" option from that.  This of
course leads to all kinds of entertaining fun.

One could argue that these two options conflict with each other, but if true,
that should be a diagnosed error.

Also, there's no -static-libc++ equivalent to -static-libstdc++, so it would be
nice if the -static-libstdc++ were repurposed to mean "whatever C++ standard
library we're using, link it statically" and then land something like 
https://reviews.llvm.org/D37726 that gives it an alias name that's more
appropriate for the non-libstdc++ case.
