[LLVMdev] Bringing in the Nios2 code generator

[Richard Pennington]

Hi,

I have completed enough of the Nios2 code generator that I think it is 
appropriate to bring it into the source tree.

What is the best approach to take? It all sits in one directory, of 
course: lib/Targets/Nios2.

Besides that directory, the only other change I've made is to configure.

The code generator is complete, but requires more testing.

How should I proceed? Should I commit just the sources to the tree for 
review and not the changes to the configure system?

How extensive do I need to make the test cases?
