   6 // This test doesn't use -fdisable-module-hash and hence requires that
   7 // CompilerInvocation::getModuleHash() computes exactly the same hash
   8 // for c-index-test and clang, which in turn requires that the both use
   9 // exactly the same resource-dir, even without calling realpath() on it:
  10 // - a/../b/ and b/ are not considered the same
  11 // - on Windows, c:\ and C:\ (only different in case) are not the same
