if you are familiar with c/c++, you may notice the macro way of optimization sometimes should duplicate the same chunk of code for a function, like strlen() or something rather simple; a popular macro style "function" called from many places in your code may also produce such "chunks".

some people like to "#include" c/c++ source code into their parent files to build something, so that it also generates many "chunks" of function dups.

how do you call a function from outside if it is static ? i am afraid these static functions might also become "chunk" if they are linked from different object modules.
