// Check that clang can use a PCH created from libclang.

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