0006  *
0007  * This include file contains the implementation of the following
0008  * routines needed to test RTEMS floating point support:
0009  *
0010  *    FP_load( &context )
0011  *    FP_check( &context )
0012  *
0013  * FP_load   - loads the specified floating point context
0014  * FP_check  - checks the specified floating point context
0015  *
0016  * Whether the CPU model has hardware or software floating point,
0017  * these methods should put load on the floating point register set.
