           Summary: Provide options in LTO to build a PIC object file for
                    linking into a shared library.
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: lto
        AssignedTo: chandlerc at gmail.com
        ReportedBy: chandlerc at gmail.com


One of the desirable things for a linker integrated with LLVM's LTO library to
provide is linking of shared libraries from bytecode. This requires (on some
platforms/OSes) building PIC in the object file with a special flag in the
assembly step of the LTO. Once PIC can be requested from the LTO library, GNU ld
(for example) should be able to check when it is generating a shared library,
and pass along the correct options.
