/*  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.
