Middle-End function/ function pointer generation

[Johannes Ziegenbalg <johannes.ziegenbalg@xxxxxxxxxxxxxx>]

Hi guys,

I hope I'm right here. Currently I'm developing a GCC plugin and 
therefore I need to generate some code which should looks like:

typedef void (bar_fn_t)(uint32_t *);

static bar_fn_t *
resolve_bar(void)
{
    return bar;
}

The function "bar" is defined in the same file. The typedef is not a big 
deal I think, it's something like: build_pointer_type(TREE_TYPE 
(current_function_decl))
But, I stuck at this function generation, especially the return part.

Thanks for your help!!

Regards
