The whole routine/capability looks mighty suspect to me.

a) no real relationship to the the rest of objc-act.c - looks like it  
should be a separate configure-time tool.

b) out-of-date w.r.t what targets might return in registers (how about  
8*long long + 13* double) - somewhat in excess of 32 bytes.

but that's perhaps part of what's needed to be addressed with general  
forwarding/messaging etc. in 4.7.
