// Header search of "Foo/Foo.h" follows this path:

// 2. Find "Foo/Foo.h" in "nonportable-hmaps/foo.hmap".
// 3. Look for "headers/foo/Foo.h".
// 4. Find "headers/foo/Foo.h" in "nonportable-hmaps".
// 5. Return.

// There is nothing nonportable; -Wnonportable-include-path should not fire.
#include "Foo/Foo.h" // no warning
// Verify files with absolute paths in the header map are handled too.
// "Bar.h" is included twice to make sure that when we see potentially
// nonportable path, the file has been already discovered through a relative
// path which triggers the file to be opened and `FileEntry::RealPathName`
// to be set.
#include "Bar.h"
#include "Foo/Bar.h" // no warning
// But the presence of the absolute path in the header map is not enough. If we
// didn't use it to discover a file, shouldn't suppress the warning.
#include "headers/Foo/Baz.h" // expected-warning {{non-portable path}}
