Re: standard intermediate representation for C/C++ ?

In his defense, Stroustrup (the designer of C++) has tried to invent
features that replace existing usages of macros and are syntactically
better-behaved. The most recent such feature is templates (generics).


The closest thing to a DIANA-like thing for C comes from ProCASE; I think
their product is called SmartSystem. They store a syntax tree, and they
also remember the mapping between macroexpansions and that syntax tree.
As far as I know this data structure is entirely proprietary and is not
directly accessible even to customers; they use it to drive their user
interface.
