1/*  fptest.h
2 *
3 *  This include file contains the CPU dependent implementation
4 *  of the following routines needed to test RTEMS floating
5 *  point support:
6 *           FP_load( &context )
7 *           FP_check( &context )
8 *
9 *  FP_load   - loads the specified floating point context
10 *  FP_check  - checks the specified floating point context
11 *
12 *  NOTE:  These routines are VERY CPU dependent and are thus
13 *         located in in the CPU dependent include file
14 *         fptest.h.  These routines form the core of the
15 *         floating point context switch test.
