// Intentionally no #include guard.  May be included multiple times for effect.

// The files vmassert_uninstall.hpp and vmassert_reinstall.hpp provide a
// workaround for the name collision between HotSpot's assert macro and the
// Standard Library's assert macro.  When including a 3rd-party header that
// uses (and so includes) the standard assert macro, wrap that inclusion with
// includes of these two files, e.g.
//
// #include "utilities/vmassert_uninstall.hpp"
// #include <header including standard assert macro>
// #include "utilities/vmassert_reinstall.hpp"
//
// This removes the HotSpot macro definition while pre-processing the
// 3rd-party header, then reinstates the HotSpot macro (if previously defined)
// for following code.

// Remove HotSpot's assert macro, if present.
#ifdef vmassert
#undef assert
#endif // vmassert
