Actually, not quite. objc_msg_lookup does not know that the returned function returns a struct. Thus the normal forwarding handler is returned instead of the stret forwarding handler. This is why my patch adds objc_msg_send_stret, which returns the correct forwarding handler for stret. The question now is if there is need on any architecture for a special fpret forwarding handler. I can't think of any (I know x86, amd64, ppc, arm and mips don't need one), thus the question is if there is any architecture out there that would need a different forwarding handler for fpret. -- Jonathan _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
