/* 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.
