            Bug ID: 21540
           Summary: The -object_path_lto option should support paths to
                    directories
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P

It's not always possible to modify invocations to the linker, especially when
you compile 3rd party projects or use some build system. Therefore it's often
quite hard to enable LTO because linker requires unique path to
"-object_path_lto" in order to make utils like dsymutil.

The solution should be fairly simple: allow to specify path to a directory and
create whatever unique files automatically.
