* The l.lws instruction was omitted from Or1ksim originally. It is specified
|
|
* for ORBIS32, even though it is functionally equivalent to l.lwz.
|
|
*
|
|
* Having fixed the problem, this is (in good software engineering style), a
|
|
* regresison test to go with the fix.
|
|
*
|
|
* Of course what is really needed is a comprehensive instruction test...
