Well lets say this, we already support this to some extend, by using
__builtin_constant_p and then just inlining. Also there exists
already an optimization pass which does IPA constant prop.
Guess you are not well into GCC development after all.

Of course, i'm a novice because i like and i don't like the
GCC development's model.
How will it be the code using __builtin_constant_p that i don't know?
