// Test that we don't remove transitive includes of public C++ headers in the library accidentally.
// When we remove a transitive public include, clients tend to break because they don't always
// properly include what they use. Note that we don't check which system (C) headers are
// included transitively, because that is too unstable across platforms, and hence difficult
// to test for.
//
// This is not meant to block libc++ from removing unused transitive includes
// forever, however we do try to group removals for a couple of releases
// to avoid breaking users at every release.

// This test doesn't support being run when some headers are not available, since we
// would need to add significant complexity to make that work.
// UNSUPPORTED: no-localization, no-threads, no-wide-characters, no-filesystem, libcpp-has-no-incomplete-format

// When built with modules, this test doesn't work because --trace-includes doesn't
// report the stack of includes correctly.
// UNSUPPORTED: modules-build

// This test uses --trace-includes, which is not supported by GCC.
// UNSUPPORTED: gcc

// This test is not supported when we remove the transitive includes provided for backwards
// compatibility. When we bulk-remove them, we'll adjust the includes that are expected by
// this test instead.
// UNSUPPORTED: transitive-includes-disabled

// Prevent <ext/hash_map> from generating deprecated warnings for this test.
