How to resolve heap object`s virtual function call at compile time

[shark]

Hi, everyone,
    I`ve a question about inlining virtual functions.
    G++ could inline those object`s virtual function which are allocated
on stack because they have type informations,  but how about objects
allocated on the heap? Can i force add a type info to it and let g++
resolve the virtual function call at compile time (not through vtables
). I tried use static_cast, but this would make a implicit call to ctor
. And also, pattern crtp ask you to build the whole type which means you
have to resolve all the function calls yourself.
   Thanks for you help
Best Regards
