// REQUIRES: ondisk_cas
// This test checks that we correctly handle situations where a spurious modular
// dependency (1) turns otherwise textual dependency into modular (2).
//
// (1) For example #include <Spurious/Missing.h>, where the framework Spurious
// has an umbrella header that does not include Missing.h, making it a textual
// include instead.
//
// (2) For example when compiling the implementation file of a module Mod,
// #included headers belonging to Mod are treated textually, unless some other
// module already depends on Mod in its modular form.
// RUN: rm -rf %t
// RUN: split-file %s %t
