   1 // Some command-line arguments used for compiling translation units are not
   2 // compatible with the semantics of modules or are likely to differ between
   3 // identical modules discovered from different translation units. This test
   4 // checks such arguments are removed from the command-lines: '-include',
   5 // '-dwarf-debug-flag' and '-main-file-name'. Similarly, several arguments
   6 // such as '-fmodules-cache-path=' are only relevant for implicit modules, and
   7 // are removed to better-canonicalize the compilation.
