Is your question why there are so many lines in the .tu dump?  The
answer to that is that all the intrinsic functions and builtin types are
included.

Yes, this was my question, but Generic will be transformed to Gimple after that, 
so, why there are no builtin types in Gimple as well ? 

if they ( intrinsic functions and builtin types) are not transfoemed in Gimple, 
CFG, SSA, ... did we realy need to inculde them in the generic form ?

thanks
