   1 // Ensure the path to the modulemap input is included in the module context hash
   2 // irrespective of other TU command-line arguments, as it effects the canonical
   3 // module build command. In this test we use the difference in spelling between
   4 // module.modulemap and module.map, but it also applies to situations such as
   5 // differences in case-insensitive paths if they are not canonicalized away.
