/*  fptest.h

 *

 *  This include file contains the CPU dependent 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

 *

 *  NOTE:  These routines are VERY CPU dependent and are thus

 *         located in in the CPU dependent include file

 *         fptest.h.  These routines form the core of the

 *         floating point context switch test.
