I think I've found the error:

The Buffer contains: include "../Target.td" and length is 23.
The file that tablegen is looking for is therefore: "../Target.td".

However, in the assertion you assert an empty buffer and that is not what 
you want, I suppose. If you change line 114 to != instead ==, then the 
assertion doesn't fail.

The next problem, on my system (Interix - you remember - Hey, some LLVM 
program is working :O ), is however, that it cannot find the ../Target.td 
file. At the moment I see some more bugs luring ahead in the TableGen code. 
More on that later.
