- * \ingroup Utilities

- * Tests that the CPU and Operating System support the vector unit which was compiled for. This
- * function should be called before any other Vc functionality is used. It checks whether the program
- * will work. If this function returns \c false then the program should exit with a useful error
- * message before the OS has to kill it because of an invalid instruction exception.
- *
- * If the program continues and makes use of any vector features not supported by
- * hard- or software then the program will crash.
- *
- * Example:
- * \code
- * int main()
- * {
- *   if (!Vc::currentImplementationSupported()) {
- *     std::cerr << "CPU or OS requirements not met for the compiled in vector unit!\n";
- *     exit -1;
- *   }
- *   ...

- * \endcode
- *
- * \return \c true if the OS and hardware support execution of the currently selected SIMD
- *                 instructions.
