/**
* @file
* @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.
