Hi Seb,

the code stays in symbol-db plugin, but it's an MVC pattern so they're 
quite decoupled, even if not at all.

well, no. I think what you're looking for is 
http://www.gnu.org/software/cflow/

I would use clang for the completion and symbol-db for static file analysis.

yes but we would have a really bad performance. That's because with 
ctags you have to use a top-down approach instead of a bottom-up with clang.
The top down approach requires high usage of regexes, data dictionaries 
and guessing. That's why its complexity soon becomes unmaintainable and 
error prone.
The bottom up approach is much more a low level parsing task, but we've 
already have it done with the clang compiler. Each C expression is then 
immediately solved with return type, members, etc.
