[cfe-dev] Generated function call

[Wei Pan]

Hi all,

I tried to twist a bit the AST by turning a very simple statement into a
function  and invoking in a statement as follows

void caller() { global_var++; }

===>

void _implicit_body() {  global_var++; }  // _implicit_body added into the
translation unit via addDecl

void _implicit_invoker(void *f) {
    void (*fptr)()  = (void(*)()) f;
    fptr();
}

void caller() {
   _implicit_invoker((void*)implicit_body); // CallExpr
}

The generated AST looks fine. However the generated code is broken since
there is *no* code generated for function _implict_body.  I am wondering if
there is a way to mark a function such that codegen always generates code
for this function.

Thanks,

Wei
