 * @brief Floating Point Register Pressure and Check
 *
 * This include file contains the implementation of the following
 * routines needed to test RTEMS floating point support:
 *
 *    FP_load( &context )
 *    FP_check( &context )
 *
 * FP_load   - loads the specified floating point context
 * FP_check  - checks the specified floating point context
 *
 * Whether the CPU model has hardware or software floating point,
 * these methods should put load on the floating point register set.
