0007  *  point support:
0008  *           FP_load( &context )
0009  *           FP_check( &context )
0010  *
0011  *  FP_load   - loads the specified floating point context
0012  *  FP_check  - checks the specified floating point context
0013  *
0014  *  NOTE:  These routines are VERY CPU dependent and are thus
0015  *         located in in the CPU dependent include file
0016  *         fptest.h.  These routines form the core of the
