be examined more closely:

* A basic assembly parser is present now and seems to parse most things.

There are a few things that need to be looked at:
|

- There are some instructions that are not generated by the backend
|

and have not been tested as far as the parser is concerned.
|

- The assembly parser does not use any MicroBlaze specific directives.

I should investigate if there are MicroBlaze specific directive and,

if there are, add them.
