+// 2) Replace the value "-fdebug-compilation-dir" flag to "Output"
+//      (this is the temp directory used by lit).
+// 3) Manually run clang-cc1, objcopy and ld invocations.
+// 4) Copy the binary and .dwo file to the Inputs directory. Make sure the
+//    .dwo file will be available for symbolizer (use test RUN-lines to copy
+//    the .dwo file to a directory
