test/VFS/real-path-found-first.m

// This test is for cases where we lookup a file by its 'real' path before we
// use its VFS-mapped path. If we accidentally use the real path in header
// search, we will not find a module for the headers.  To test that we
// intentionally rebuild modules, since the precompiled module file refers to
// the dependency files by real path.
