// TODO(hardening): remove in LLVM 20.
// This test ensures that enabling assertions with the legacy `_LIBCPP_ENABLE_ASSERTIONS` now enables the extensive
// hardening mode.

// `check_assertion.h` is only available starting from C++11 and requires Unix headers.
// UNSUPPORTED: c++03, !has-unix-headers
// The ability to set a custom abort message is required to compare the assertion message.
// XFAIL: availability-verbose_abort-missing
// Note that GCC doesn't support `-Wno-macro-redefined`.
// ADDITIONAL_COMPILE_FLAGS: -U_LIBCPP_HARDENING_MODE -D_LIBCPP_ENABLE_ASSERTIONS=1
