digitalmars.D - Dustmite for C++

I'm aware of that Dustmite, given infinite compute capacity, can 
minimize all languages if it's just fed the right compiler 
command. How much more efficient would Dustmite become if it, in 
the C++ case, was served a complete parse tree produced by Clang 
or GCC?

This is probably not very useful, but there are test-case 
reduction programs out there. Just search for "test case 
reduction" or "delta debugging"?

Here's one interesting project:

Yeah, I also found the approach they take in creduce sounds 
interesting. Did you get anything interesting out of it?
