I'm not convinced at all. Isn't that a flavor of the same old "XML 
solves all your problems" argument again that was so popular ten years 
ago ? How do you express domain-specific semantics, such as C++ symbol 
lookup, in a generic querying language ?

As I mentioned, there is no reason not to scale Synopsis up to using a 
different backend to store its IR in (such as a database), if that will 
indeed improve performance. Let's cross that bridge when we come to it...

I'm afraid I'm not quite there yet, though it shouldn't be too long. 
(Still need to figure out how to configure system header search paths 
and system macros, etc.. Before clang, I used some heuristics from 
installed system compilers (GCC, MSVC). I'm not sure yet how clang is to 
be used in that respect, i.e. whether it figures any of this out on its 
own, or whether I need to feed all of those in explicitly.

That being said, by all means come and play with the code and provide 
feedback. Nothing will help more to get things done !
I'll gladly help you getting started...

Regards,
         Stefan
