here:

int
estimate_num_insns (gimple stmt, eni_weights *weights)
{
        /* Do not special case builtins where we see the body.
           This just confuse inliner.  */
...
        else if (!(decl = gimple_call_fndecl (stmt))
                 || !(node = cgraph_get_node (decl))
                 || node->definition)
          ;

a simple re-org will fix that.  I'll do that.
